Warren Weaver (July 17, 1894 – November 24, 1978) [1] was an American scientist, mathematician, and science administrator. [2] He is widely recognized as one of the pioneers of machine translation and as an important figure in creating support for science in the United States.
In its modern sense, molecular biology attempts to explain the phenomena of life starting from the macromolecular properties that generate them. Two categories of macromolecules in particular are the focus of the molecular biologist: 1) nucleic acids , among which the most famous is deoxyribonucleic acid (or DNA), the constituent of genes , and ...
The starting point, that is the time from which these codes are in effect (usually retroactively), varies from group to group, and sometimes from rank to rank. [7] In botany and mycology, the starting point is often 1 May 1753 (Linnaeus, Species plantarum). In zoology, it is 1 January 1758 (Linnaeus, Systema Naturae, 10th Edition).
In Weaver's view, disorganized complexity results from the particular system having a very large number of parts, say millions of parts, or many more. Though the interactions of the parts in a "disorganized complexity" situation can be seen as largely random, the properties of the system as a whole can be understood by using probability and ...
It is not known whether homochirality existed before life, whether the building blocks of life must have this particular chirality, or whether life must be homochiral at all. [8] [9] What do all the unknown proteins do? Two decades since the first eukaryotes were sequenced, the "biological role" of around 20% of proteins are still unknown. [10]
The idea of using digital computers for translation of natural languages was proposed as early as 1947 by England's A. D. Booth [5] and Warren Weaver at Rockefeller Foundation in the same year. "The memorandum written by Warren Weaver in 1949 is perhaps the single most influential publication in the earliest days of machine translation."
The Applied Mathematics Panel (AMP) was created at the end of 1942 as a division of the National Defense Research Committee (NDRC) within the Office of Scientific Research and Development (OSRD) in order to solve mathematical problems related to the military effort in World War II, particularly those of the other NDRC divisions.
Life, by David E. Sadava et al., is a 1983 biological science textbook, under continual revision, used at many colleges and universities around the United States of America. [1] As of 2024, it is in its twelfth edition. It is published by W.H. Freeman through MacMillan Learning.
