I will describe von Neumann’s elegant idea for sampling from the exponential distribution, Forsythe’s generalization for sampling from a probability distribution whose density has the form exp(−G(x)), where G(x) is easy to compute (e.g. a polynomial), and my refinement of these ideas to give an efficient algorithm for generating pseudo-random numbers with a normal distribution. Later developmen...

those without environmental insults or behavioural problems, as suggested in Drs Newell and Green's algorithm, diagnoses would have been missed. The three studies quoted were performed more than 10 years ago. Subsequent refinements in techniques of chromosome analysis allow identification of minor chromosome abnormalities that might previously not have been recognised-for example, in our series...

trumpet of praise, and his enemies tried to give him a parting kick. We have nothing unkind to say of Sir George. True, lie once insulted the Calcutta doctors grievously by insinuating that they made false returns of their earnings. He was taken to book promptly and sharply on this account at the time. He was able to show that he was misled by statistics and made a frank and generous amende. Th...

George Klein, famous cancer biologist and acclaimed writer on matters of science, human responsibility, and the human condition, decorated by innumerable awards, honorary doctorates and other honors, elected member of this Academy and many other learned societies, including the Royal Swedish Academy of Sciences and the American Philosophical Society, and Member of the Nobel Assembly of Karolins...

George Buchanan was born in the year 1881 in Myddleton Square, Islington, where his father was in medical practice. He received his early education at University College School, and subsequently at the adjacent college. During this period he worked under T. H. Key and de Morgan; he acquired much fondness for classics, notably the English classics, and he was awarded medals in biology and chemis...

Recent work in philosophy of language has raised significant problems for the traditional theory of propositions, engendering serious skepticism about its general workability. These problems are, I believe, tied to fundamental misconceptions about how the theory should be developed. The goal of this paper is to show how to develop the traditional theory in a way which solves the problems and pu...
