    Extractions: Alexander Dickson, who became Colonel of the 16th Regiment of Foot, was born in 1743, and was served heir to his three cousins, the ladies foresaid, on 11th July, 1794. He married Susanna Jane, daughter of Sir Henry Moore, Governor of New York, and afterwards divorced her. The old tower of Hartree was demolished by him, and he built the older part of the present house on an adjoining site. As he had no children, he intended a cousin, Major Andrew Douglas, who lived with him at Hartree, to be his heir, but he outlived him, and died in 1817, leaving his lands in Kilbucho to his relative, John Dickson of Kilbucho and Coulter, subject to a liferent in favour of Euphemia Helen Smeaton, the widow of Major Andrew Douglas. Sir Peter WEDDERBURN Admitted as advocate, rose to be clerk to the Privy Council, and a Lord of Session, under the title of Lord Gosford, which he took from the estate of Gosford, county of Lothian, purchased by him from Sir Alexander Auchmuthie in 1659.

    Extractions: Uma vez realizada a separação dos movimentos nucleares dos eletrônicos, serão feitas neste capítulo considerações apenas sobre a solução da equação de Schrödinger para a componente eletrônica, ou seja, a solução da eq.11. Pode-se imaginar que se a equação de Schrödinger pode ser resolvida exatamente para sistemas monoeletrônicos, o problema da solução exata para sistemas multieletrônicos está associado ao termo de repulsão intereletrônica (eq.6). Na verdade, se o termo de repulsão eletrônica pudesse ser subdividido em termos de componentes monoeletrônicas, a solução da equação de Schrödinger para um sistema contendo 2 n elétrons seria dada por uma série de equações semelhantes à eq.11, sendo uma equação para cada elétron. Em outras palavras, ter-se-ia um conjunto de 2 n equações do tipo: Equação (12) sendo o operador de energia cinética do i -ésimo elétron, o termo de atração de todos os N núcleos pelo i -ésimo elétron e corresponderia a um operador de repulsão eletrônica efetivo também do i -ésimo elétron.

    Extractions: For articles on related subjects see ANALOG COMPUTER; BUSH, VANNEVAR; DIGITAL COMPUTERS: HISTORY: EARLY; and HARTREE, DOUGLAS. In a paper published in the Journal of the Franklin Institute in 1931, Vannevar Bush described a machine (Fig. 1) that had been constructed under his direction at M.I.T. for the purpose of solving ordinary differential equations. He christened the machine a differential analyzer . This was what would now be called an "analog" computer, and was based on the use of mechanical integrators that could be interconnected in any desired manner. The integrator was in essence a variable-speed gear, and took the form of a rotating horizontal disk on which a small knife-edged wheel rested. The wheel was driven by friction, and the gear ratio was altered by varying the distance of the wheel from the axis of rotation of the disk. The principle is illustrated in Fig. 2. The use of mechanical integrators for solving differential equations had been suggested by Kelvin, and various special-purpose integrating devices were constructed at various times. Bush's differential analyzer was, however, the first device of sufficiently general application to meet a genuine need, and in the period immediately before and during World War II quite a number of these devices were constructed. The one shown in Fig. 4 was installed at the Mathematical Laboratory in Cambridge, England. The integrators and torque amplifiers can be clearly seen in Fig. 4, together with the system of shafting used for effecting the connections. Changing the problem was a job for someone who did not mind hands covered in oil. The output table on which the results were plotted directly in graphical form can be seen in Fig. 4, which also shows a number of similar tables that were used for input, an operator being employed to turn a handle so that a cursor followed a curve. It is a comment on the primitive state of automatic control in the period in question that automatic curve-following devices were not provided until later. The accuracy attainable in a single integrator was about one part in three thousand, but of course a lower accuracy was to be expected in the solution.

    At present the douglasKroll implementation can be used at all levels of theorywhereas Dyall's approach is currently available at the hartree-Fock level.

    Extractions: Subsections All methods which include treatment of relativistic effects are ultimately based on the Dirac equation, which has a four component wave function. The solutions to the Dirac equation describe both positrons (the ``negative energy'' states) and electrons (the ``positive energy'' states), as well as both spin orientations, hence the four components. The wave function may be broken down into two-component functions traditionally known as the large and small components; these may further be broken down into the spin components. The implementation of approximate all-electron relativistic methods in quantum chemical codes requires the removal of the negative energy states and the factoring out of the spin-free terms. Both of these may be achieved using a transformation of the Dirac Hamiltonian known in general as a Foldy-Wouthuysen transformation. Unfortunately this transformation cannot be represented in closed form for a general potential, and must be approximated. One popular approach is that originally formulated by Douglas and Kroll and developed by Hess . This approach decouples the positive and negative energy parts to second order in the external potential (and also fourth order in the fine structure constant

    http://www.applegate.co.uk/fam_his/272-280.htm
    
    Extractions: The earliest record we have of Glenholm is about 1200, when Gillecrist, the son of Daniel at Glenwhym, appears as a witness to the perambulation of the marches of Stobo. The lands were rated at £30 of old extent, and for a time their name was the surname of the family who were in possession. About the year 1233 Sir Nicholas 'Glenynwim,' who was rector in the church at Yetholm was a witness to charters of the lands of Stobo. Estuene de Glenwhym of the county of Peebles signed the Ragman Roll in 1296. and he appears a few years afterwards as a witness to charters by Sir Simon Fraser dealing with the lands of Kingledoors, Hopcarton and Happrew. Later, in 1451 there was 'Robert of Glenquhym,' who had a grant of the lands of Wrae, and in 1466 'Dene James Glenquham, who was a monk of Kelso. James of Douglas was seventh Earl of the great House of Douglas, and is well enough known in history as a man of violent and impetuous temperament. He murdered Sir David Fleming of Cumbernauld and Biggar in 1406, and the year before he burned the town of Berwick, perhaps a patriotic but undoubtedly a cruel act. In 1437 he was created Earl of Avondale, and made Justice-General of Scotland. His third daughter, Janet, married Robert, first Lord Fleming, which is interesting in view of the subsequent connection of that family with the parish.
