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 earliest manifestations, molecular biology—the name was coined by Warren Weaver of the Rockefeller Foundation in 1938 [1] —was an idea of physical and chemical explanations of life, rather than a coherent discipline.
Homochirality is an obvious characteristic of life on Earth, yet extraterrestrial samples contain largely racemic compounds. [7] 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.
The overall grade for the class is then typically weighted so that the final grade represents a stated proportion of different types of work. For example, daily homework may be counted as 50% of the final grade, chapter quizzes may count for 20%, the comprehensive final exam may count for 20%, [1] and a major project may count for the remaining ...
As the study of biology became increasingly specialized, specific codes were adopted for different types of organism. To an end-user who only deals with names of species, with some awareness that species are assignable to genera , families , and other taxa of higher ranks, it may not be noticeable that there is more than one code, but beyond ...
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.
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 ...
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.
