Sir Maurice Wilkes, going strong at 91 Peter Davidson, Information Age In the days when the Cambridge Mathematical Laboratory, birthplace of the world's first stored program computer (EDSAC), was an appropriated anatomy dissecting room redolent with formalin, entry was by an otherwise nondescript green wooden door. These days, entry to the engineering department of what is now the Cambridge Computer Laboratory, in a new high-tech building on the northern outskirts of the leafy university town, is guarded by sophisticated electronic and biometric technology. Emeritus professor Sir Maurice Wilkes, father of EDSAC (Electronic Delay Storage Automatic Calculator), submits to its security scrutiny without demur every day as he goes to his office.

91. Lady Jeffrey Obituary douglas hartree at Manchester was extremely sorry to lose such a valued colleaguewhen she returned to Cambridge in 1938, to an Official Fellowship and http://cwp.library.ucla.edu/articles/jeffreys/jeffreys-obituary.html

The Independent (London) December 22, 1999, Wednesday HEADLINE: OBITUARY: BERTHA JEFFREYS BYLINE: R M Williams BERTHA SWIRLES, Lady Jeffreys, did important research on quantum theory, particularly in its early days, and her association with Girton College, Cambridge, as student and Fellow, spanned more than 70 years. Born in Northampton in 1903, she was involved in the world of education from her earliest days. Her widowed mother was a primary-school teacher and various aunts were also teachers. She attended Northampton School for Girls and then went up to Girton, in 1921, to read Mathematics, graduating with first class Honours. She became a research student of R.H. Fowler, one of a distinguished company of his students which included several Nobel prizewinners such as P.A.M. Dirac and Subrahmanyan Chandrasekhar. She spent the winter semester of 1927-28 in Gottingen, where she worked under Max Born and Werner Heisenberg and interacted with many of the other leading continental workers in the relatively new field of quantum mechanics; it was an exciting time. By the time she was awarded her PhD in 1929, she was already an Assistant Lecturer in Manchester. This was followed by similar appointments in Bristol and at Imperial College, London, and then in 1933 she returned to Manchester as a Lecturer in Applied Mathematics. Douglas Hartree at Manchester was extremely sorry to lose such a valued colleague when she returned to Cambridge in 1938, to an Official Fellowship and Lectureship in Mathematics at Girton.

Green York University christo@yorku.ca Charles Babbage (1791-1871) is widely-known today as the inventor of several machines that were mechanical precursors of the modern electronic digital computer. He frequently receives mention in introductory computer science texts, and is often called the "inventor of the computer," or the "first computer scientist." Alongside of such celebratory blurbs about Babbage , one can often find brief accounts of Ada Lovelace (1815-1852), who is known primarily for having published a series of notes about one of Babbage's machines the Analytical Engine. In recent years, both figures have expanded their range from computer science textbooks to cognitive science textbooks as well. They are typically described as having foreshadowed the foundational article of faith of cognitive science

Relativistic effects are of the same size as correlation contributions although small compared to the non-relativistic Hartree-Fock limit (9.14 au). The accurate determination of atomic and molecular dynamic and static polarizabilities and hyperpolarizabilities is an active and challenging field of research. The polarizabilities are important in the treatment of weakly interacting systems, atomic scattering processes, optical and dielectric properties of ionic substances and for core-polarization and core-valence correlation effects (Bonin and Kresin 1997, Shanker et al et al 1984). As a second-order response property to the externally applied electric field, the static dipole polarizability

100. O Método De Hartree Translate this page Em um trabalho pioneiro, douglas R. hartree sugeriu que a equação de Schrödingerpoderia ser resolvida adequada e aproximadamente da maneira sugerida acima. http://www.chemkeys.com/bra/md/tdqq_4/metlca_1/omdh_3/omdh_3.htm

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. As funções
