%%%                        used the author name D. R. Hartree, and we

%%%                        difficult for a historian to create a book

%%%                        During World War I (1914--1918), Douglas
%%%                        Hartree interrupted his undergraduate studies
%%%                        at the University of Cambridge in 1915 to
%%%                        join his engineer father, William Hartree (8
%%%                        April 1870--27 April 1943), to work on
%%%                        numerical computations.  The two continued to
%%%                        collaborate until William Hartree's death.
%%%                        As Darwin's biographical memoir for Douglas

%%%
%%%                            ... the relationship, was an exceptional
%%%                            one, because the son was the leader and
%%%                            the father ranked as the junior in this
%%%                            work.
%%%
%%%                        Hartree's work during World War I was on
%%%                        modeling anti-aircraft gunnery and
%%%                        ballistics, and he was commissioned as a
%%%                        Lieutenant in the Royal Naval Volunteer
%%%                        Reserve.  Darwin's memoir reports on page 14:
%%%
%%%                            His [Douglas Hartree's] main activity was
%%%                            in the integration of the differential
%%%                            equations for trajectories, and in this
%%%                            at the age of 20 he introduced a reform
%%%                            which may not now seem very
%%%                            revolutionary, but which must have been
%%%                            rather disturbing for the older
%%%                            practitioners of the science. By
%%%                            tradition the angle of elevation of the
%%%                            trajectory had always been used as the
%%%                            independent variable, and the
%%%                            co-ordinates and the time were expressed
%%%                            in terms of it. He showed that there
%%%                            would be great advantages in using the
%%%                            time itself as the independent variable,
%%%                            and expressing all the other quantities
%%%                            in terms of that. He introduced this
%%%                            practice and it is now generally
%%%                            accepted.
%%%
%%%                        After the war, in 1919, Douglas Hartree
%%%                        resumed his undergraduate studies at
%%%                        Cambridge, earning in 1922 a Bachelor of Arts
%%%                        degree with First Class Honours in Part I of
%%%                        the Mathematical Tripos, and Second Class
%%%                        Honours in Part II of the Natural Sciences
%%%                        Tripos.  He remained at the University of
%%%                        Cambridge for graduate studies in physics
%%%                        under Ralph Howard Fowler, and completed his
%%%                        doctorate in 1926 under [then] Sir [later
%%%                        Lord] Ernest Rutherford (Nobel Prize in
%%%                        Chemistry in 1908), Fowler's father-in-law.
%%%

%%%                        doctoral advisor: some say Fowler, but the
%%%                        Mathematics Genealogy Project says
%%%                        Rutherford.]
%%%
%%%                        Hartree spent several months (late August,
%%%                        1928--spring, 1929) with Niels Bohr's group
%%%                        in Copenhagen, Denmark.  That was a
%%%                        productive visit, and he collaborated there
%%%                        with the Swedish physicist Ivar Waller on an
%%%                        important paper that we mention later.
%%%
%%%                        From October 1929 to 1937, Douglas Hartree
%%%                        held the Boyer Chair of Applied Mathematics
%%%                        in the University of Manchester.  He was
%%%                        elected as a Fellow of the Royal Society on 5
%%%                        May 1932, at the age of 35.  In 1937, he
%%%                        became Chair of Theoretical Physics at
%%%                        Manchester, but spent most of the period
%%%                        1940--1945 on leave, working with the
%%%                        Ministry of Supply on wartime projects.
%%%
%%%                        Douglas Hartree's activities at the Ministry
%%%                        of Supply included directing two groups, one
%%%                        solving differential equations with the
%%%                        differential analyzers (some of which was
%%%                        related to the development of nuclear
%%%                        weapons), and the other working on the theory
%%%                        and analysis of the magnetron, an important
%%%                        component in the new radar systems that were
%%%                        critical for air and naval operations.
%%%
%%%                        Douglas Hartree was elected President of the
%%%                        Manchester Literary and Philosophical Society
%%%                        in 1939, and in 1945, became Professor of
%%%                        Engineering Physics at the University of
%%%                        Manchester.  In 1946, he returned to the
%%%                        University of Cambridge as the Plummer
%%%                        Professor of Mathematical Physics, succeeding
%%%                        his graduate advisor, Ralph H. Fowler.  In
%%%                        1948, for several months, he was Acting
%%%                        Director of the Numerical Analysis Institute,
%%%                        National Bureau of Standards, UCLA, in Los
%%%                        Angeles, California.  Hartree held his
%%%                        position at Cambridge until his death on 12
%%%                        February 1958, at the age of just 61.  See
%%%                        entries Hartree:1958:NTP and
%%%                        SwirlesJeffreys:1987:DRH for reports of his
%%%                        death.
%%%
%%%                        Some quotes from Darwin's memoir about
%%%                        Hartree give a flavor of the significance of
%%%                        Hartree's work:
%%%
%%%                            [p. 104] In the work he undertook his
%%%                            unselfishness was outstanding in the
%%%                            sense that he was always ready to help
%%%                            people with their problems, even at the
%%%                            expense of his own work. Actually this
%%%                            was perhaps a good thing, because there
%%%                            were a number of other people attacking
%%%                            the same kinds of problem in atomic
%%%                            physics as he was, so that the work would
%%%                            have been done anyhow, whereas there was
%%%                            no one in the world with the same gift
%%%                            for putting into shape any problem that
%%%                            was susceptible to numerical analysis.
%%%
%%%                            [p. 104] He played the piano, but his
%%%                            main activity in music was in an
%%%                            orchestra where he played the drums, and
%%%                            sometimes acted as conductor. [Page 526
%%%                            of entry Simoes:2000:QCG reports that
%%%                            Hartree also founded the Faculty of Music
%%%                            at Manchester University, and was its
%%%                            first Dean].
%%%
%%%                            [p. 105] He considered later that the
%%%                            most important event in his scientific
%%%                            career was a visit to Cambridge paid by
%%%                            Niels Bohr in 1921, who gave a course of
%%%                            lectures on the [old] quantum theory.
%%%
%%%                            [p. 106] He also did work on various
%%%                            details of the Bohr atom model in the
%%%                            course of which he estimated the
%%%                            corrections that might be expected for
%%%                            various atomic energy levels on account
%%%                            of the inner shells of electrons. All
%%%                            this work was the germ that later
%%%                            flowered into one of his major
%%%                            contributions to physics, that of the
%%%                            self-consistent Field.
%%%
%%%                            [p. 107] Working in this manner he
%%%                            attacked problems very much more advanced
%%%                            than others had attempted. For example,
%%%                            sometimes working in conjunction with his
%%%                            father, he solved the problem for such
%%%                            elements as copper and even mercury. All
%%%                            this work was being done with pencil and
%%%                            paper, but the situation was changed
%%%                            about this time, when Vannevar Bush
%%%                            developed his differential analyzer in
%%%                            America. This immediately excited
%%%                            Hartree's interest.
%%%
%%%                            [p. 107] Hartree saw that this machine
%%%                            would much lighten the very heavy
%%%                            numerical work of his computations on
%%%                            self-consistent fields. He therefore made
%%%                            a journey to Boston to see the machine
%%%                            work, and on returning home he set up one
%%%                            for himself, the first model being made
%%%                            in 1934 of Meccano [a well-known British
%%%                            toy modeling system, similar to the
%%%                            American Erector sets] parts [see entry
%%%                            Hartree:1938:MID]. Starting from this,
%%%                            with the help of A. [Arthur] Porter, he
%%%                            obtained a number of results and later,
%%%                            again with his help and aided by a
%%%                            generous gift of 6000 pounds from Sir

%%%                        and Douglas Hartree's strong background in

%%%                        solution.
%%%
%%%                        One of his first approaches expressed the

%%%                        one-particle functions, and he showed how to

%%%                        set of coupled differential equations, one
%%%                        for each particle, each of which could be
%%%                        solved in turn from a suitable starting
%%%                        guess, and the process iterated until
%%%                        acceptable numerical convergence was reached:
%%%                        a ``self-consistent field (SCF)''.  That now
%%%                        widely used term is often credited to Douglas
%%%                        Hartree, but he learned of the idea from an
%%%                        earlier visitor to the Bohr Institute, Robert
%%%                        Bruce Lindsay (see entries Lindsay:1924:U).
%%%
%%%                        It is not clear whether Hartree and Lindsay
%%%                        communicated in the 1920s via letter, or
%%%                        whether the SCF idea had become common lore
%%%                        at the Bohr Institute: their visits to
%%%                        Copenhagen were six years apart.  See entry
%%%                        Martinez:2016:HFM for a discussion.
%%%
%%%                        Lindsay's autobiography (entries

%%%                        suggests that Lindsay himself made little use
%%%                        of the idea, and that it was Douglas Hartree
%%%                        who made significant use of the SCF method,
%%%                        despite the enormous tedium of doing this
%%%                        with mechanical calculators.  Lindsay and
%%%                        Hartree had substantial letter correspondence
%%%                        in the 1930s, and were able to meet in person
%%%                        in Manchester in May 1937.

%%%                        ``Hartree's method'' in the chemistry and
%%%                        physics literature of the time.
%%%
%%%                        However, it was soon realized that a simple
%%%                        product of one-particle functions failed to
%%%                        guarantee a critical symmetry property of the
%%%                        N-particle wavefunction: it must be symmetric
%%%                        for particles of integer spin (known as
%%%                        bosons), and antisymmetric for particles of
%%%                        half-integer spin (known as fermions).
%%%                        Without that symmetry, it is not possible to
%%%                        guarantee computational bounds on the
%%%                        solution of the wave equation.
%%%
%%%                        The simplest way to supply that symmetry is
%%%                        to replace the product by a special form of a
%%%                        matrix: a permanent for bosons (particles of
%%%                        integral spin: 0, 1, 2, ...), and a
%%%                        determinant for fermions (particles of

%%%                        of atoms, molecules, and solids.  The need to

%%%                        of Legendre functions or spherical harmonics,
%%%                        are named after him: see entry

%%%                        Dirac discussed particle permutations, but
%%%                        did not use determinants, nor did he
%%%                        reference the Waller/Hartree paper.
%%%
%%%                        Slater referred to the Dirac and
%%%                        Waller/Hartree papers, but simplified their
%%%                        work, and also introduced the spin property
%%%                        into the computation.  According to page 192
%%%                        of entry SwirlesJeffreys:1987:DRH, Slater
%%%                        visited Hartree in early 1930 [in
%%%                        Manchester], and several sources suggest that
%%%                        they maintained extensive correspondence for
%%%                        many years.
%%%
%%%                        Fock mentioned the Waller/Hartree work, but
%%%                        without a literature citation.  He did not
%%%                        cite the Dirac and Slater work. See entry
%%%                        Martinez:2018:VFI for a dissertation on
%%%                        Fock's work.
%%%
%%%                        Slater determinants, as they are now widely
%%%                        known, are the building blocks for
%%%                        representing wavefunctions, and the
%%%                        computational algorithm that uses just a
%%%                        single determinant is called the
%%%                        ``Hartree--Fock method'', giving credit also
%%%                        to Fock.  Some authors since then also honor
%%%                        Slater, using the name
%%%                        ``Hartree--Fock--Slater method''.
%%%
%%%                        The first published mention of the phrase
%%%                        ``Hartree--Fock method'' is believed to be
%%%                        due to Igor Tamm and D. Blochinzev (entry
%%%                        Tamm:1932:AEM): see page 6 of entry
%%%                        Martinez:2016:HFM.  However, page 84 of entry
%%%                        Martinez:2018:VFI reports that the term did
%%%                        not become widespread until the 1950s.
%%%
%%%                        The qualifiers ``Hartree--Fock--Dirac'' and
%%%                        ``Dirac--Fock'' are also encountered, but
%%%                        generally refer to inclusion of relativistic
%%%                        effects, as introduced by Dirac in 1928.
%%%
%%%                        The building blocks of single-particle
%%%                        functions are often called ``Slater-type
%%%                        orbitals'' (STOs), implying use of
%%%                        exponentials of scaled radial distances.
%%%                        That choice is inspired by the exact
%%%                        solutions of the quantum mechanical wave
%%%                        equation for the hydrogen atom, which have
%%%                        the same exponential behavior.
%%%
%%%                        Later, in August 1949, Samuel Francis
%%%                        (`Frank') Boys in Cambridge (see entries
%%%                        Boys:1950:EWF and Coulson:1973:SFB) proposed
%%%                        instead the use of exponentials with squared
%%%                        distances, called ``Gaussian-type orbitals''
%%%                        (GTOs), because they enormously simplify the
%%%                        computation of two-, three-, and four-center
%%%                        integrals needed in molecular calculations,
%%%                        despite their incorrect limiting behavior for
%%%                        large distances.  That representational error
%%%                        is mitigated by the fact that the
%%%                        contributions to total energies, and most
%%%                        atomic and molecular properties, in that
%%%                        region are tiny.
%%%
%%%                        Recently, in an effort to further simplify
%%%                        the integral problem, B-spline
%%%                        representations of one-particle functions
%%%                        have been investigated for atomic
%%%                        Hartree--Fock calculations: see entry
%%%                        Waide:2020:BPS.
%%%
%%%                        Douglas Hartree was well aware of the
%%%                        problem of numerical solutions of the
%%%                        wave equation.  On the first page of
%%%                        entry Hartree:1947:CAS, he wrote:
%%%
%%%                            ``It has been said that the tabulation of
%%%                            a function of one variable requires a
%%%                            page, of two variables a volume, and of
%%%                            three variables a library; but the full
%%%                            specification of a single wave function
%%%                            of neutral Fe [iron]is a function of
%%%                            seventy-eight variables. It would be
%%%                            rather crude to restrict to ten the
%%%                            number of values of each variable at
%%%                            which to tabulate this function, but even
%%%                            so, full tabulation of it would require
%%%                            $10^{78}$ entries, and even if this
%%%                            number could be reduced somewhat from
%%%                            considerations of symmetry, there would
%%%                            still not be enough atoms in the whole
%%%                            solar system to provide the material for
%%%                            printing such a table.''
%%%
%%%                        In that paper, Hartree goes onto discuss
%%%                        wavefunctions antisymmetry via Slater
%%%                        determinants, problems of integral
%%%                        computations, configuration interaction (CI),
%%%                        polarization, relativistic effects,
%%%                        two-particle functions, ionization,
%%%                        excitation, stability of negative ions,
%%%                        highly excited states, and continuum states.
%%%                        That is a remarkably broad study that was
%%%                        done before electronic computers began to
%%%                        make such work feasible.
%%%
%%%                        In the 1930s and 1940s, Hartree was much
%%%                        involved in the design and use of
%%%                        differential analyzers for the numerical
%%%                        solution of differential equations arising in
%%%                        varies areas of engineering and science, and
%%%                        wrote books about them (see entries
%%%                        Hartree:1946:CMR, Hartree:1947:CMR,
%%%                        Hartree:1949:CIM, Hartree:1949:DAM,
%%%                        Hartree:1950:CIM, Hartree:1953:CIM,

%%%                        Hartree:1984:CMRb, Hartree:2012:CIM).
%%%
%%%                        Page 141 of entry Gavroglou:2011:DRH suggests
%%%                        that it was a letter from John C. Slater at
%%%                        MIT to Hartree that drew first attention to
%%%                        Vannevar Bush's machines (see entries
%%%                        Bush:1931:DAN and Owens:1986:VBD), and led to
%%%                        Hartree's visit in 1933 to MIT.  Hartree had
%%%                        written to Slater to express his pleasure
%%%                        with Slater's papers on exchange forces,
%%%                        determinantal wavefunctions, and the
%%%                        self-consistent field method (entries
%%%                        Slater:1929:TCS and Slater:1930:NHM).  As
%%%                        quoted earlier, on return to Manchester, in
%%%                        1934, Hartree built a model differential
%%%                        analyzer with Meccano parts, and in 1935, a
%%%                        full-scale one, that was later doubled in
%%%                        size, and used in World War II research.
%%%                        Hartree's successes inspired the construction
%%%                        in Britain of three more differential
%%%                        analyzers by 1940, at the University of
%%%                        Cambridge [by John Edward Lennard-Jones],
%%%                        Queen's University in Belfast, Northern
%%%                        Ireland [by H. S. W. Massey and others: see
%%%                        entry Massey:1938:SSD] and the Royal Aircraft
%%%                        Establishment in Farnborough (about 50km
%%%                        southwest of London).  A 12-integrator
%%%                        differential analyzer as built in Oslo,
%%%                        Norway in 1938 [see entries
%%%                        Rosseland:1937:ODN and Holst:1996:SRO], and
%%%                        was the world's largest until about 1942.
%%%                        Several more machines were built in Canada,
%%%                        Japan, and United States up to about 1951,
%%%                        when interest in early general-purpose
%%%                        digital computers began to grow, and interest
%%%                        in specialized analog devices waned.
%%%
%%%                        The famous trilogy by Per-Olov Lowdin
%%%                        (entries Lowdin:1955:QTM{a,b,c}) laid the
%%%                        groundwork for extensions and generalizations
%%%                        of the single-determinant Hartree--Fock
%%%                        methods.  Expansions of the wavefunction as
%%%                        sums of determinants with numerically
%%%                        optimized coefficients lead to a method
%%%                        that Hartree and Swirles (entry
%%%                        Hartree:1937:ECI) called ``configuration
%%%                        interaction (CI)''.  Importantly, it can be
%%%                        shown that this expansion, in exact
%%%                        arithmetic, provides rigorous upper bounds to
%%%                        the energy eigenvalues of the wave equations,
%%%                        and that the bounds are always improved by
%%%                        the addition of more terms in the sum.  This
%%%                        important result is known as the
%%%                        ``Rayleigh--Ritz variational principle''.
%%%
%%%                        A variant of CI, called ``multiconfiguration
%%%                        Hartree--Fock (MCHF)'' optimizes both the
%%%                        one-particle functions and the expansion
%%%                        coefficients, although usually with a much
%%%                        shorter CI expansion.  See entries
%%%                        Hibbert:2019:CFF and FroeseFischer:1997:CAS
%%%                        for an overview.
%%%
%%%                        Many computational methods derived since the
%%%                        work of Hartree and Lowdin attempt to
%%%                        minimize the CI term count by optimization of
%%%                        the one-particle functions (orbitals), and by
%%%                        summation to infinity of certain terms via
%%%                        rewriting similar to that found in the
%%%                        mathematical expansion of the reciprocal
%%%
%%%                            1 / (1 - x) = 1 + x + x**2 + x**3 + ...
%%%
%%%                        Such rewritings are often handled by the
%%%                        famous Feynman diagrams that help scientists
%%%                        identify, and visualize, the most important
%%%                        terms in the sum of a potentially infinite
%%%                        number of terms.
%%%
%%%                        Most subsequent numerical solutions of the
%%%                        quantum wave equation are based on models
%%%                        that use one or more Slater determinants.  To
%%%                        provide further simplifications, scientists
%%%                        may replace the complicated one- and
%%%                        two-particle integrals of products of
%%%                        one-particle functions, and associated
%%%                        operators, with simpler models that
%%%                        approximate the difficult integrals by
%%%                        numerical parameters whose values are
%%%                        adjusted to match solutions expected for
%%%                        certain atoms, molecules, or solids, and then
%%%                        used to predict solutions for related
%%%                        systems.  These techniques are often termed
%%%                        ``semi-empirical methods'', in comparison to
%%%                        ``ab initio methods'' that use accurate
%%%                        computations of integrals, and multiple
%%%                        determinants in wavefunction expansions.
%%%
%%%                        Thus, much numerical work towards solving the
%%%                        wave equations in quantum chemistry and
%%%                        quantum physics in the 20th Century has been
%%%                        rooted in the Hartree--Fock method, and that
%%%                        name consequently appears in a large number
%%%                        of titles of scientific articles in those
%%%                        fields.

%%%                        To give a flavor of the impact of Hartree's

%%%                        found more than 21,000 such titles.  The

%%%                        Part 3 of this bibliography supplies more

%%%                        Apart from his important contributions to
%%%                        quantum computations, Hartree was a leader in
%%%                        Britain in the introduction of numerical
%%%                        methods to many other areas of science and
%%%                        engineering, and was one of the pioneers in
%%%                        the use and promotion of early (analog and
%%%                        digital) mechanical and electronic computers.
%%%                        Hartree's influence on computing, and on the
%%%                        British computing industry, is vast.
%%%
%%%                        All of the 114 Hartree publications listed in
%%%                        the bibliography of the Darwin memoir are
%%%                        included in this bibliography.  That list is
%%%                        incomplete, because at version 1.05, there

%%%                        Fischer biography of Hartree lists 6 books
%%%                        and 113 articles: all of them have been

%%%                        Douglas Hartree worked on government projects
%%%                        in World Wars I and II, and although it is
%%%                        likely that there were reports written by him
%%%                        about that work, there is little record from
%%%                        those ten years, likely due to government and
%%%                        military secrecy restrictions.  There are 13
%%%                        article entries from 1939--1945, all from
%%%                        normal engineering and scientific journals,
%%%                        but none at all from 1914--1918, and only two
%%%                        before 1920, from his public school journals
%%%                        in 1912 and 1913.  Subsequent searches of the
%%%                        UK National Archives identified five
%%%                        technical reports by Hartree during World War
%%%                        II in the years 1941--1943: entries for them

%%%                        However, in writing the book, she was able to

                 Zeit. f{\"u}r Phys. 9, p. 1 (1922); The Theory of
                 Spectra and Atomic Constitution (Camb. Univ. Press,

                 Phys. 12, p. 342 (1923)] in a more or less qualitative
                 form. This theory is accepted completely in the present
                 paper, which deals with an attempt to make a more
                 quantitative application of it to the investigation of
                 the spectra and structure of certain atoms. The general
                 idea of this attempt is the determination of an
                 electric field such that the orbits specified by the
                 application of the quantum conditions to the motion of
                 an electron in this field shall have the energies
                 assigned to the different terms in the optical and
                 X-ray spectra. The dimensions of the orbits and
                 variation of time along them can then be

                 often carried out by the approximate method of Jeffreys
                 [10], which was developed independently with special
                 reference to wave mechanical applications by [Gregor]
                 Wentzel [(1898--1978)] [11], [Hendrik Anthony] Kramers
                 [(1894--1952)] [12], and [L{\'e}on] Brillouin
                 [(1889--1969)] [13], by whose names it is commonly
                 known in such applications. We have not used this
                 approximation, since it is probably not at all good for
                 the range of small energies in which the most
                 interesting part of the fine structure occurs,
                 \ldots{}''. Many physics publications refer to that
                 method as the ``WKB approximation'', published in three
                 papers in German and French physics journals in 1926,
                 but here Hartree credits H. (Harold) Jeffreys (22 April
                 1891--18 March 1989), ``On Certain Approximate
                 Solutions of Linear Differential Equations of the
                 Second Order'', Proc. Lond. Math. Soc. {\bf s2-23},
                 428--436 (not 420, as cited by Hartree), 1924 (doi:
                 10.1112/plms/s2-23.1.428). The paper was received 15
                 March 1923, read 26 April 1923, revised 17 April 1924.
                 It, plus two adjacent papers by Jeffreys, were
                 recommended for the Adams Prize of the University of
                 Cambridge. The volume year is 1924, but the running
                 page headers in the paper say April 26, 1923. Thus,
                 some later authors refer more properly to the JWKB
                 method. See further description in the article
                 https://en.wikipedia.org/wiki/WKB_approximation.",

                 seeing the photographs of Dr. Bush's machine was that
                 they looked as if some one had been enjoying himself
                 with an extra large Meccano set. This suggested the
                 possibility of trying to build, wholly or at least
                 mainly out of standard Meccano parts, a model version
                 of the machine which would serve as a demonstration
                 model to illustrate qualitatively the general
                 principles on which it works. The result was successful
                 beyond expectation; we found it possible to build,
                 almost entirely in Meccano, a model differential
                 analyser (10), which would work not only qualitatively
                 but quantitatively to an accuracy of about 2 per cent.,
                 which could be (and has been) improved by more
                 attention to details of design. \ldots{} I regard the
                 success of this model as a striking tribute to the
                 versatility and practical value of the Meccano
                 system.''",

                 Millard F. Manning, University of Pittsburgh,
                 Pittsburgh, Pennsylvania. Shortly after the outbreak of
                 the war in Europe, Mr. W. Hartree sent to this country
                 a set of the results of his recent unpublished
                 self-consistent field calculations with the request
                 that they be made available to interested physicists in
                 this country. Only the wave functions and not the
                 effective nuclear charges were received. The
                 undersigned has calculated these and supplied the
                 textual material. Professor Hartree has commented on
                 the manuscript but has not seen the proof.
                 Correspondence about this paper and requests for
                 reprints should be addressed to the undersigned. M. F.
                 M.''. According to \cite[pp.
                 128--129]{Simoes:2000:QCG}, Douglas Hartree had written
                 to John C. Slater in 1939, expressing his concern about
                 a coming war in Europe, and wanting to ensure that SCF
                 data for completed calculations should not be lost.
                 Slater responded that the results should be sent to him
                 at MIT, checked, and published in The Physical
                 Review.",

                 process of checking is necessary to ensure that any
                 results obtained are not vitiated by undetected
                 mistakes. A treatment of numerical methods which does
                 not pay some attention to this aspect of the subject
                 seems to me to be quite unrealistic. In some worked
                 examples I have deliberately introduced mistakes in
                 order to show how, by suitable checking procedure, they
                 can be detected, diagnosed, and corrected.''",

                 August 1976 is attached. It runs: 'In the Lent Term
                 1958, Hartree told me that he was about to go into the
                 Evelyn Nursing Home. He expected to be out in time to
                 give a course of lectures on P.D.E.s that he had
                 announced for the second half of the term, but that he
                 would, as a precaution, like to give me his notes so
                 that I could deputise for him if necessary.\par

                 Nursing Home and was taken to Addenbrooke's Hospital

                 provide a general introduction to contemporary
                 developments in the field of calculating instruments

                 historical side of the subject, with appreciation shown
                 for the vision and foresight of key pioneers Charles
                 Babbage and Lord Kelvin. This is a concise and

%%%   Part 2 (of 3): Publications about Douglas Hartree and his works
%%%
%%% Entries that refer to Hartree or his works (a large number of
%%% articles with Hartree or Hartree--Fock in the title appear in the
%%% physics literature, and have mostly been ignored here).  However,
%%% entries up to about 1960 with Hartree in titles ARE included here,
%%% because they laid the groundwork for the understanding of his
%%% methods.  From roughly that time, electronic computers became
%%% available to scientists, and the count of publications crediting
%%% Hartree increased dramatically.
%%%
%%% Several of the entries here that do not mention Hartree in their
%%% titles were returned by the Royal Society journal Web site in a
%%% search for ``Douglas Rayner Hartree''.

  abstract =     "In a recent communication to this Society Dr Hartree
                 has put forward a method for calculating the field of
                 anatom containing many electrons. Each orbit --- to
                 borrow a metaphor from the old quantum theory --- is
                 related to a wave-function $ \Psi $ which obeys
                 Schr{\"o}dinger's equation. The potential energy used
                 in this equation is due partly to the field of the
                 nucleus, and partly to the fields of the electrons in
                 the other orbits. The latter are calculated upon
                 Schr{\"o}dinger's interpretation of the wave-function,
                 that $ | \Psi |^2 $ is the density of charge, measured
                 in electronic charges per unit volume. It is not the
                 purpose of this paper to discuss the practical methods
                 of obtaining wave-functions which reproduce the fields
                 from which they are derived; but to relate these
                 wave-functions and their energy parameters to those of
                 the accepted theory.",

                 and the whole of chemistry are thus completely known,
                 and the difficulty is only that the exact application

                 configuration space. It is shown that the approach $

                 important special case of the complete degeneracy of
                 the term system, however, $ \Psi $ can be approximated
                 by a product of two determinants [formula (50) of the

                 The equations aren't much more complicated than

                 Firstly, an account of the model machine is given in
                 the form of a published paper. Part I gives a
                 descriptive account of (i) the extension and
                 modification of the model, and (ii) the main points in
                 the construct ion and adjustment of the full-size
                 machine. Part II deals with a study of an automatic
                 control problem. Part III gives details of the
                 applications of the machine to other problems.",

                 after fleeing the Nazis in the 1930s and moving to
                 England. The thesis title and dates are from \cite[p.
                 9]{Meyer-Spasche:2016:PPO}. That title is not found in
                 the Library Hub Discover or Manchester University

                 but entry \cite{Bracewell:1993:OB} also says 1940. No
                 electronic copy is available. The year disagreement is
                 explained in \cite[pp. 9--10]{Meyer-Spasche:2016:PPO}:
                 ``OB submitted his thesis in April 1940, and on May 3,
                 the committee accepted an application to examine his
                 thesis `Solutions of the Spheroidal Wave Equation'
                 (Buneman 1940). The internal examiner was to be Dr
                 Squire [\cite{Gates:1962:HBS}]. \ldots{} As things
                 developed, his applications for a teaching post were
                 thwarted, because on June 3, 1940, Oscar Bunemann was
                 interned as an enemy alien. When the committee met for
                 his oral PhD examination on June 8 [1940], it noted
                 that Buneman had been interned and queried whether an
                 examiner could be sent to hold the oral at `the place
                 of internment' as it had been indicated that he would
                 not be released to attend the oral. The official
                 document for his doctoral degree is dated May 1, 1942.
                 In practice, though, the degree was granted to him in

                 self-consistent field solution of the many-electron

                 one-electron equation for the Schr{\"o}dinger
                 one-electron equation. It has been shown earlier that
                 in the solution without exchange the necessary
                 potential function can be found just as in the
                 nonrelativistic case. The numerical solution for the
                 inner shells of Cu$^+$ is outlined, and tables of the
                 resulting energy parameters and charge density
                 distribution are given. The corrections introduced into
                 the charge density distribution are small, except near
                 the nucleus, for this comparatively light ion. The
                 energy parameters are noticeably affected, and the
                 known splitting of the $ (p)$ and $ (d)$ energy
                 parameters is shown. Approximate calculations of the
                 magnetic interaction energies between two electrons

  abstract =     "This communication deals with the general theory of
                 obtaining numerical electronic wave functions for the
                 stationary states of atoms and molecules. It is shown
                 that by taking Gaussian functions, and functions
                 derived from these by differentiation with respect to
                 the parameters, complete systems of functions can be
                 constructed appropriate to any molecular problem, and
                 that all the necessary integrals can be explicitly
                 evaluated. These can be used in connexion with the
                 molecular orbital method, or localized bond method, or
                 the general method of treating linear combinations of
                 many Slater determinants by the variational procedure.
                 This general method of obtaining a sequence of
                 solutions converging to the accurate solution is
                 examined. It is shown that the only obstacle to the
                 evaluation of wave functions of any required degree of
                 accuracy is the labour of computation. A modification
                 of the general method applicable to atoms is discussed
                 and considered to be extremely practicable.",

                 \alpha $ method, an approximate method for solving the
                 Hartree--Fock equations where the complicated
                 two-electron Coulomb and exchange integral terms are
                 replaced by much simpler integrals involving a
                 one-particle scaled pseudopotential, with $ \alpha $
                 being the scale factor. Slater used $ \alpha = 1 $, but
                 later independent derivations of Slater's method found
                 $ \alpha = 2 / 3 $ (see
                 \cite{Gaspar:1954:AHF,Herman:1963:ASC,Kohn:1965:SCE,Slater:1972:SEC,Connolly:1977:XM}).
                 The method required computer solutions, and did not
                 become practical until the mid 1960s, but already in
                 1952, Pratt \cite{Pratt:1952:WFE} succeeded in using it
                 for a computation on the copper ion. According to Morse
                 \cite{Morse:1982:JCS}, it was made self-consistent
                 about 1965 (reference?? --- perhaps
                 \cite{Herman:1963:ASC}). However, it was considerably
                 faster than ab initio computations that handled all of
                 the difficult integrals properly, and allowed
                 computations on transition metal complexes that were
                 completely intractable in 1970 with the ab initio
                 approach. Keith Johnson at MIT, Frank Smith and Don
                 Ellis at Florida, and dozens of doctoral students at
                 Florida, MIT, Northwestern, and many other
                 universities, wrote hundreds of papers and
                 dissertations on computations with pseudopotential
                 methods, density functional methods, and discrete
                 variational methods, all of whose roots are in this
                 paper.",

                 field (s.c.f.) method, to take some account of
                 polarization interaction between two outer electrons,
                 is worked out numerically, up to a point, for H$^-$.
                 The two-electron wave function is a product of two
                 one-electron radial functions and a function X of the
                 angle between the two radii. Several integrals must be
                 calculated and a boundary value problem for X must be
                 solved prior to the stage of ordinary Hartree
                 calculations. These fundamental computations are made
                 here, but the routine solution of the radial Hartree
                 equations has been omitted; instead the Stevenson
                 corrections to the total energy are estimated by
                 perturbation methods. These corrections seem just about
                 large enough to yield an electron affinity for H$^-$
                 (something not achieved by s.c.f. or variation methods
                 without polarization). However, a good deal of labor is
                 involved beyond that required for s.c.f. solutions, and
                 it is not certain that this particular method of
                 including polarization effects is to be preferred to a
                 combination of variation and s.c.f. calculations.",

                 this process is shown to take place without effective
                 propagation. The `turbulent' flow pattern created,
                 eventually, under nonlinear conditions is calculated
                 numerically, demonstrating the tendency towards
                 randomization of the initial drift energy. The effect
                 stops `runaway' in about 100 plasma periods after which
                 there is `heating' by `collective collisions'

                 methods for treating an inhomogeneous system of
                 interacting electrons are developed. These methods are
                 exact for systems of slowly varying or high density.
                 For the ground state, they lead to self-consistent
                 equations analogous to the Hartree and Hartree--Fock
                 equations, respectively. In these equations the
                 exchange and correlation portions of the chemical
                 potential of a uniform electron gas appear as
                 additional effective potentials. (The exchange portion
                 of our effective potential differs from that due to
                 Slater by a factor of 2/3.) Electronic systems at
                 finite temperatures and in magnetic fields are also
                 treated by similar methods. An appendix deals with a

                 his contributions to biology were not negligible. Also,
                 during a good part of his life he devoted almost as
                 much attention to religion as to science and, yet
                 again, there was the public figure active in numerous
                 charitable pursuits. Many-sided as Charles Coulson's
                 life was, no picture of the man would be true that did
                 not convey the essential unity of everything he did ---
                 concern being perhaps the key word to describe the
                 common strand that ran through all his works. To
                 describe them and the man is thus not an easy task.",

                 conference time to me to try to explain the
                 possibilities of the calculations he wanted me to do.
                 As a result of all this reading and discussion, there
                 began to dawn on me the notion of representing the
                 screening effect of the inner electron groups on the
                 outer ones in terms of continuous distributions of
                 negative charge calculated by solving the time equation
                 of the orbital motion, i.e., finding the average time
                 spent by each electron in any spherical shell at a
                 given distance from the nucleus. From this one was
                 rather naturally led to endeavor to find such
                 distributions of charge as would lead to quantized
                 orbits which in turn were consistent with the charge
                 distribution which produced them. Thus arose the
                 concept of self-consistency, which so far as I was
                 aware had not been suggested or used by any theoretical
                 atomic investigator at that time. It is of course
                 impossible to prove that Bohr did not himself suggest
                 it to me directly or indirectly. \ldots{} My scheme,
                 however, crude though it may have been, made no use of
                 empirical data from spectroscopy or any other source.
                 To me the matter is of some importance, since
                 ultimately D. R. Hartree applied the scheme to the
                 quantum mechanical evaluation of atomic fields under
                 the title ``self-consistent field'' method. In one of
                 his early papers on this subject Hartree gave me credit
                 for making calculations based fundamentally on the idea
                 adopted, and other writers since, notably J. C. Slater,
                 have mentioned my contribution, but have implied that
                 there was a lot of other work of similar description
                 going on at that time. I believe, however, that the
                 story as I have stated it is correct. The obvious
                 question to raise here is why I did not myself follow
                 up the self-consistent idea in quantum mechanics. I
                 shall wait to discuss this in connection with the
                 beginning of my professional academic career after I
                 returned to the United States in 1923.''",
  remark-2 =     "From pp. 86--87: ``I found the Heisenberg matrix
                 calculus puzzling, as my background in algebra did not
                 include much on this type of symbolism. I could
                 appreciate Schr{\"o}dinger's work better since it
                 involved the wave equation which I was probing in the
                 acoustics class. What I did not at all see was how this
                 new point of view could be applied to polyelectronic
                 atoms, and here of course I missed my golden
                 opportunity, for this was just waiting to fall into
                 someone's lap. What happened was that D. R. Hartree in
                 Manchester in England took it up and showed how the
                 self-consistent field idea could be translated into
                 quantum mechanical terms or more specifically into wave
                 mechanical language. In 1928 he began to publish a
                 series of elaborate papers which continued for many
                 years. The question arises, why had I not seized this
                 opportunity independently? \par

                 The answer is a relatively simple one. I did not know
                 enough about the manipulation of partial differential
                 equations to see how the Schrodinger wave equation
                 could be solved by numerical means for a potential
                 energy function represented only by a table of
                 numerical values. I realize that this is a poor excuse.
                 The natural thing would have been to go to an applied
                 mathematician to ask him how the problem should be
                 tackled and in particular how one could proceed to
                 match a numerical solution proceeding out from the
                 origin with a similar solution proceeding in from
                 infinity. The fact remains that there were few applied
                 mathematicians in the modern sense in the United States
                 at that time.''",

                 took me a long time really to understand how. the new

                 the eigenvalue problem pounded into me in any
                 mathematics course. Hartree with his Cambridge
                 mathematics training had this at his finger tips. Well,
                 these are vain regrets, but they are regrets all the
                 same and represent keen realization of my genuine
                 shortcomings as a physicist. As matters turned out and

                 most practical kind, qualified him to play a major role
                 at that critical moment. He had personal qualities of
                 no less value. He was entirely without any sense of his
                 own importance and could work, seemingly on equal
                 terms, with those much younger than himself. He never
                 attempted to lay down the law, and detested people who
                 did. The only time I saw him really angry was once when
                 he had just returned from a visit to the ACE project at
                 the National Physical Laboratory where he had
                 encountered such a person. It was, in no small measure,
                 due to Hartree that computer applications in Cambridge
                 got off to such a good start.''",

  abstract =     "The Quantum Universe is the first popular book to give
                 a non-mathematical pictorial account of quantum
                 physics, the foundation of our current understanding of
                 nature. For so long the province of mathematicians and
                 physicists alone, the beauty and significance of
                 quantum mechanics has remained hidden to the
                 nonspecialist. Yet its impact on technology has been
                 enormous. The modern electronics industry with the
                 silicon chip that has revolutionised so many aspects of
                 modern life owes its existence to an understanding of
                 the quantum nature of semiconductors. The text explains
                 exactly what quantum mechanics is in a simple
                 nonmathematical way, and is complemented throughout by
                 many superb colour and black-and-white photographs
                 illustrating the varied facets of quantum phenomena.
                 The Quantum Universe will provide a fascinating and
                 accessible introduction to one of the most important
                 scientific disciplines of the twentieth century.
                 Final-year students at school, general readers with an
                 interest in science, and undergraduates in science
                 subjects will all be able to enjoy and benefit from

  abstract =     "Douglas Hartree, who was a mathematical physicist at
                 the University of Manchester and the University of
                 Cambridge during the first half of this century,
                 examined the possibilities for numerical solutions of
                 the many-body problem in quantum mechanics which did
                 not permit analytic, closed-form results. In an attempt
                 to surmount the mathematical complexities associated
                 with multi-electron atoms, Hartree proposed the method
                 of self-consistent fields as an approximation scheme
                 which would give numerical forms of atomic wave
                 functions via iterative solution of the Schr{\"o}dinger
                 equation. Hartree was quick to recognize the need for
                 automatic computation, both analog and digital, for the
                 practical implementation of the technique. To this end,
                 he investigated the application of analog differential
                 analyzers to the problem before realizing the
                 superiority of digital computation. The question of the
                 first self-consistent field calculations to be run on
                 an electronic digital machine is addressed in an effort
                 to clarify misinformation in the existing literature
                 about the use of early computers to perform Hartree
                 computations.",

                 of renowned numerical analyst Douglas Hartree, Buneman
                 began using his computing abilities to simulate the
                 magnetron, a device for generating powerful radar
                 waves. He aided the understanding of it through
                 computation of its electron orbits and fields, and the
                 device became very important to Britain's
                 defense.\par

                 `The magnetron made airborne radar possible, which made
                 a big difference to the submarine war in the Atlantic
                 and also in night bombing and bombing through clouds,'
                 said Sidney Self, a professor emeritus of mechanical
                 engineering who first met Buneman in England in the
                 early 1950s.\par

                 `It has often been said that while the atomic bomb
                 ended the war, radar won it.'\par

                 After coming to Stanford first as a visiting professor
                 in 1957, he [Buneman] joined the Stanford faculty
                 permanently in 1960. He directed some of his energy
                 toward simulating space and fusion plasmas on the most
                 advanced computers available while working on
                 computational theory with Gene Golub, professor of
                 computer science, and others.\par

                 In the early 1970s, Buneman `showed how to solve
                 Poisson's equation in a very elegant and stable manner,
                 which had an enormous impact on the scientific
                 computing community,' Golub said.''",

                 Astrophysics. It was built by a Norwegian instrument
                 firm, borrowing much of its details from the famous MIT
                 design by Vannevar Bush. For a few years this
                 mechanical analytical tool ranked as the world's
                 foremost differential equation solver. The Oslo
                 analyzer was technically advanced, highly accurate,
                 and, surprisingly, it was the most accessible large
                 computational resource available to theoretical
                 physicists in the world. Its success was primarily due
                 to Professor Svein Rosseland. He was a bright, young
                 astrophysicist who had impressed his fellow physicists

                 practical terms it was substantially undocumented and
                 unfinished. Its design had evolved by iterating each
                 important function through trials and refinement.
                 \ldots{} There is good reason to believe Rosseland's
                 was the first complete and thorough documentation of
                 the design (see Fig. 3). His extensive notes and
                 sketches would later come in handy for Bush when other
                 analyzers were to be made. (The first copy was made for
                 the Moore School of Electrical Engineering in
                 Philadelphia, Pennsylvania. The second was built by the
                 Metropolitan-Vickers Company for Douglas R. Hartree in
                 Manchester, England. A third was built in Boston some
                 years later and used by the U.S. Army's Aberdeen
                 Proving Grounds. Rosseland's carefully prepared

                 with the field of computational atomic structure,

                 (MCHF) approach and the manner in which this approach
                 is used in modern physics. Beginning with an
                 introduction to computational algorithms and procedures
                 for atomic physics, the book describes the theory
                 underlying nonrelativistic atomic structure
                 calculations (making use of Brett--Pauli corrections
                 for relativistic effects) and details how the MCHF
                 atomic structure software package can be used to this
                 end. The book concludes with a treatment of atomic
                 properties, such as energy levels, electron affinities,
                 transition probabilities, specific mass shift, fine
                 structure, hyperfine-structure, and autoionization.

                 differential analyzers were scientists working at
                 universities in the fields of quantum mechanics,
                 theoretical chemistry and mathematics. The first and

                 to given an accuracy of 2 percent (lower than a
                 full-scale machine that was accurate to 0.1 percent).
                 The success of this model got funding for a bigger
                 machine that was built for Manchester University by
                 Metropolitan-Vickers Electrical Company Ltd., using
                 drawings supplied by Vannevar Bush, and delivered in
                 1935. It had 4 integrators, and was smaller than the
                 Bush's 6-integrator machine at MIT in Cambridge, MA,
                 USA. Further success with the new machine in Manchester
                 generated funding to expand it to 8 integrators. During
                 World War II, Hartree's differential analyzer was taken
                 over by the Ministry of Supply, and from pp. 48--49:

                 calculations relating to the development of the radar
                 cavity magnetron, the study of anti-aircraft gun

                 from the point of view of modern chemistry. This
                 detailed and unique historical narrative is fascinating

  remark =       "From pp. 1275--1277: ``Although Inga Fischer was not
                 on the patent of Xylocaine [Lidocaine in the USA], it
                 has been said that she synthesized this particular
                 compound for the very first time. \ldots{} After some
                 time, L{\"o}fgren managed to secure 50g of
                 2,6-xylidine, which was enough to make a single batch
                 of Xylocaine for further tests. Failure was not an
                 option, so L{\"o}fgren wanted the synthesis to be
                 performed by someone he trusted. Since Inga had a
                 reputation of being very skillful and precautious in
                 the laboratory, it fell on her fate to make the first
                 synthesis of Xylocaine on a larger scale. Xylocaine is
                 one of the most successful commercialized scientific
                 advances ever made in Sweden, and to participate in
                 such project as a young scientist gave Inga a good
                 start in her career. \ldots{} The practical usefulness
                 of Xylocaine made local anesthesia an attractive
                 alternative to narcosis in many cases of light surgery
                 and it also became very popular among dentists. For
                 these two reasons, the world market for local
                 anesthetics increased dramatically after the release of
                 Xylocaine in 1948. \ldots{} During the conference [in
                 1948 in Paris, France], Inga Fischer was introduced to
                 Charles Coulson, which resulted in Inga spending the
                 winter of 1948--1949 doing research at King's College
                 in London. \ldots{} The paper \cite{Coulson:1949:XNM}
                 pointed out which way the development of more accurate
                 methods had to take, which a few years later resulted
                 in the development of the unrestricted Hartree--Fock
                 (UHF) formalism. Furthermore, this was one of the
                 earliest papers showing that the VB and MO methods are
                 two different approximations of the more general method
                 of configuration interaction (CI). It seems fair to say
                 that the Coulson--Fischer paper is a milestone in the
                 development of quantum chemistry.''",

                 full-scale differential analyser, and a copy of the
                 machine constructed for Manchester University was
                 ordered from Metropolitan--Vickers. This necessitated
                 Wilkes making a trip to Manchester, where he met
                 Douglas Hartree in person for the first time. Hartree
                 collected Wilkes from the railway station in his motor
                 car, and put him up in his home. It was the beginning
                 of a lasting friendship. When Hartree moved to the
                 University of Cambridge after World War II, he became a
                 kind of godfather to the Laboratory. However, no sooner
                 was the differential analyser delivered than Britain
                 was at war. The facilities of the Laboratory were taken
                 over by the Ministry of Supply, and Wilkes was enlisted
                 in the scientific war effort.''",

                 Addison-Wesley, and the book appeared in 1951 under the
                 title The preparation of programs for an electronic
                 digital computer (18). The book was essentially the
                 same as the September 1950 report, with the addition of
                 a foreword by Hartree and Americanized spelling. Wilkes
                 included as co-authors Wheeler and Gill (the latter had
                 developed ground-breaking debugging techniques), and
                 the book became known as Wilkes, Wheeler and Gill, or
                 WWG for short. It was the first textbook on
                 programming, and because it was published at a time
                 when the first computers were just coming into
                 operation it rushed in to fill the vacuum of knowledge
                 about programming. The book influenced programming
                 techniques almost everywhere (indeed, the subroutine
                 library, organized in the manner invented by Wheeler,
                 remains a fundamental principle of most programming
                 systems up to the present day). WWG was perhaps the
                 single most important outcome of the EDSAC.''",

                 writing this program he made one of the most profound
                 discoveries in computing: that getting programs right
                 was very difficult. His was a short program of 126
                 instructions, but it contained about 20 errors. It was
                 only after at least a dozen attempts that he finally
                 coaxed the correct results out of the machine. \ldots{}
                 the realization came over me with full force that a
                 good part of the remainder of my life was going to be

                 remarkable instinct for doing history, and in another
                 life that is the path his academic career might have
                 taken. His special interest was Charles Babbage, of
                 whom he first learned from Hartree in 1946. It says
                 much of Wilkes's commitment that in May 1949 --- the
                 month in which EDSAC began to work --- he found time to
                 visit the Science Museum in London to study Babbage's
                 scientific manuscripts. He was the first person of the
                 computer era to go back to the primary sources. In 1971
                 he gave the principal address (33) at a memorial

  abstract =     "The German student Oscar B{\"u}nemann, in trouble with
                 the Nazi authorities in the mid-1930s, chose to
                 emigrate to Britain and pursue a PhD there. After
                 emigration, his surname appears as Buneman. On the
                 verge of completing his degree in 1940, he was detained
                 as an enemy alien and spent almost a year in
                 internment. Upon release, he found work as an atomic
                 scientist in England, and went on to lead a post-war
                 career as a pioneering plasma physicist in the
                 USA.\par

                 We study forced migration of European scientists before
                 and during the Second World War, and scientific
                 patronage in the host countries. Buneman's case is
                 interesting from several points of view. Being a
                 non-Jewish, non-communist, anti-Nazi activist, he
                 belongs to a group not much investigated by historians.
                 His emigration from Germany was facilitated by his
                 family's business contacts in Britain. Being caught up
                 in the wave of detainments of enemy aliens in 1940, he
                 was assisted in pleading for release by the Society for
                 the Protection of Science and Learning, the archives of
                 which abound with information about refugee scientists
                 from Nazi Germany. We have also had access to material
                 not available to previous investigators, kindly

                 fa{\c{c}}on trop partielle en histoire des sciences.
                 Plus sp{\'e}cifiquement, nous nous penchons sur les

                 r{\'e}aliste scientifique de sa discipline. Cette base

                 debate on the interpretation of these two major
                 theories of the XXth century, following an approach
                 that clearly claims dialectical materialism --- an
                 ideology then largely imposed by the Soviet authorities
                 in the USSR --- as fundamental. Our work mostly focuses
                 on this aspect of Fock's career, explored too partially
                 in the history of science. More specifically, we
                 reconsider the scientific and philosophical roots of
                 the non-orthodox interpretations of quantum mechanics
                 and general relativity developed by Fock. By
                 reconstructing his epistemological approach we put
                 forward that the physicist was guided by an
                 antireductionist and a scientific realist conception of
                 his discipline. This basis gives us the possibility to
                 discuss the reasons why dialectical materialism was a
                 real influence on the scientist thought. Thus, by
                 following the observation of the sincere adoption by
                 Fock of the Soviet ideology, we put back the question
                 of the interpretation of the theories of modern physics
                 in its socio-cultural context. We observe Fock's
                 trajectory as a defender of quantum mechanics and
                 relativity theory against the different ideological and
                 political attacks they may undergo in Soviet Union. We
                 also study the influence of context on the actual
                 wording of their interpretations and finally we develop
                 the issues related to their diffusion in the local and
                 worldwide community of physicists. To summarize, this
                 thesis helps to reconsider the interest of Fock's
                 thought in the history of modern physics",

%%% ====================================================================
%%%   Part 3 (of 3): Publications on the large scale eigenproblem
%%%
%%% This problem occurs in the configuration interaction (CI) method
%%% introduced by Douglas Hartree in 1937 (entry Hartree:1937:ECI),
%%% where the matrices are sparse, and usually randomly so, but also
%%% often diagonally dominant (i.e., the (i,i) diagonal element is
%%% larger in magnitude than other elements in row or column i).
%%%
%%% When symmetry requirements produce blocking of the matrices,
%%% algorithmic tuning can produce substantial speedups.
%%%
%%% In configuration interaction calculations, often only a few of the
%%% lowest eigenvalues, and usually, corresponding eigenvectors, are
%%% required.  The Krylov, Lanczos, and Arnoldi algorithms appear to be
%%% first methods for this problem, and several later refinements are
%%% named after Davidson and Jacobi--Davidson.
%%%
%%% Feler's method can be used to find eigenvalues near an arbitrarily
%%% chosen value, instead of just extremal eigenvalues.
%%%
%%% The need for eigensolutions of large matrices occurs in many other
%%% areas of engineering and science than quantum-mechanical CI
%%% calculations, so these methods are of broad interest.
%%%
%%% A distinguishing feature of these algorithms is that they do NOT
%%% require the full matrix $A$ in the eigenproblem $A x = \lambda x$ to
%%% be held in the computer's central memory.  Instead, they only need
%%% the ability to carry out a dot product of a row of the matrix with a
%%% given column vector.  That permits, for example, the matrix to be
%%% fetched by rows from external storage.  In some applications, I/O
%%% activity can be minimized by reconstruction in memory of the matrix
%%% row on each iteration.
%%%
%%% Entry Olsen:1990:POB reports what is believed to be the world's
%%% largest CI expansion up to that time: $10^9$ terms.  The computation
%%% time in 1989 on an IBM 3090/VF mainframe with 64MB of central memory
%%% at the Utah Supercomputing Institude [in the next building to that
%%% of the office of the bibliographer] is reported to be about 1 CPU
%%% day per iteration, but each such iteration took one wall-clock week
%%% because of I/O between central memory and external storage.
%%% Importantly, the authors did the calculations for several different
%%% CI expansion lengths to confirm the convergence predicted by the
%%% Rayleigh--Ritz variational principle.
%%%
%%% The recent entry Zbikowski:2023:BBL describes computations using CI
%%% expansions with $2 \times 10^{10}$ terms.

                 optimization procedure for solving $ A x = b $, where
                 $A$ is a real symmetric, positive definite matrix, is
                 well known. We demonstrate that a relaxed equivalence
                 is valid in the presence of errors. Specifically we
                 demonstrate that local var epsilon-orthonormality of
                 the Lanczos vectors guarantees local $ \varepsilon
                 $-$A$-conjugacy of the direction vectors in the
                 associated conjugate gradient procedure. Moreover we
                 demonstrate that all the conjugate gradient
                 relationships are satisfied approximately. Therefore,
                 any statements valid for the conjugate gradient
                 optimization procedure, which we show converges under
                 very weak conditions, apply directly to the Lanczos
                 procedure. We then use this equivalence to obtain an
                 explanation of the Lanczos phenomenon: the empirically
                 observed ``convergence'' of Lanczos eigenvalue
                 procedures despite total loss of the global
                 orthogonality of the Lanczos vectors.",

                 real, symmetric matrix eigenproblem and a version of
                 the Lanczos method obtained by removing the
                 perturbation theory `corrections' from Davidson's
                 algorithm. It is found that the convergence of
                 Davidson's method is superior to that of Lanczos only
                 if the matrix is quite strongly diagonally dominant.
                 Applications to typical matrices from nuclear structure
                 calculations, which are not very diagonally dominant,
                 show no essential difference between the convergence
                 rates. The Davidson-Lanczos method as used here is
                 capable, unlike the usual versions of the Lanczos
                 method, of direct application to the generalised
                 eigenproblem $ A x = \lambda B x $. The author shows
                 how this can be implemented and gives some examples
                 that illustrate the convergence properties.",

                 placed not only on ``what'' this pioneer of
                 computational plasma physics contributed but, of equal
                 importance, on ``how'' he made his contributions.
                 Therein lies the difference between technical
                 competence and scientific greatness. The picture which
                 emerges illustrates the open-mindedness, enthusiasm,
                 intellectual\slash physical stamina, imagination,
                 intellectual integrity, interdisciplinary curiosity,
                 and deep humanity that made this individual unique. As
                 a gentleman and a scholar, he had mastered the art of
                 making cold technical facts ``come to life.'' Oscar
                 Buneman died peacefully at his home near Stanford
                 University on Sunday, January 24th, 1993. The profound
