Watson and Crick

Watson and Crick
James Watson and Harry Crick won the 1962 Nobel Prize in Medicine. Their path-breaking work on DNA, the molecule of heredity, helped open exciting possibilities for gene-splicing and biological engineering (UPI /Bettmann Newsphoto)

A second, related change was the modern science became highly, even brutally, competitive. This competitiveness is well depicted in Noble Prize winner James Watson’s book “The Double Helix,” which tells how in 1953 Watson and an Englishman Francis Crick, discovered the structure of DNA, the molecule of heredity. A brash young American Ph.D. in his twenties, Watson seemed almost obsessed by the idea that some other research team would find the solution first and thereby deprive him of the fame and fortune he desperately wanted. With so many thousands of like-minded researchers in the wealthy countries of the world, it was hardly surprising that scientific and technical knowledge rushed toward in the postwar era. ~ Page 1000

“Genius” is a seductive term and slippery too -- used often, and frequently abused. Motivational speakers, magazine editors and authors of inspirational biographies have certainly grasped its appeal, to say nothing of the hopeful parents of tiny potentials Mozarts, Austens, and Einsteins. . . . The late French philosopher Kacques Derrida acknowledged as much when he dared to broach the subject at a formal gathering among scholars in 2003. “In according the least legitimacy to the word ‘genius’ he confessed, “one is considered to sign one’s resignation from all fields of knowledge… Thus noun “genius” he added, “makes us squirm.” Some academic observers have doubted whether a word so commonly used can possess genuine meaning or intellectual merit. Others have worried about its association with discredited theories of human superiority and inferiority. Social scientists and psychologists, meanwhile, respond by attempting to pin down the criteria of genius with greater rigor, hoping to defect its presence and understand its spread among populations for the benefit of humanity. As the psychologist Lewis Terman, a key architect of the IQ exam., put it in this landmark ‘Genetic Studies of Genius’ (1925), “The origins of genius, [and] the natural laws of its development are scientific problems of almost unequaled importance for human welfare” ~ Page 1

The fundamental biological is DNA. That is why Mendel’s defining of the gene was the unvarying bearer of hereditary traits, its chemical identification by Avery (confirmed by Hershey), and the elucidation by Watson and Crick of the structural basis of its replicative invariance, without any doubt constitute the most important discovery ever made in biology. To which of course must be added the theory of natural selection, whose certainty and full significance were established only those later discoveries. ~ Page 104

Whereas Pergamon and Ellsevier a ;has focused on expansion first and developing prestige second, the Nature publishing Group took the converse strategy -- they concentrated on building prestige ‘Nature’ first published in 1869, is one of the oldest scientific journals and built its reputation by wide recognition -- it was a journal that had a very wide “popular” readership with a large base of individual subscribers. In the 1960s it could still be found on the magazine racks of high street bookshops in the United Kingdom. It brought science to the attention of the very broad academic and lay audience with short, clear, focused articles. One of the most famous is Crick and Watson’s 1953 report of the structure of DNA -- a model of clear, concise prose, in a single page, with its unforgettably understated conclusion: “It has not escaped our notice that the specific pairing we have postulated immediately suggests a possible copying mechanism for the genetic material. ` Page 268
