About this ebook
Historically, the scientific method has been said to require proposing a theory, making a prediction of something not already known, testing the prediction, and giving up the theory (or substantially changing it) if it fails the test. A theory that leads to several successful predictions is more likely to be accepted than one that only explains what is already known but not understood. This process is widely treated as the conventional method of achieving scientific progress, and was used throughout the twentieth century as the standard route to discovery and experimentation. But does science really work this way? In Making 20th Century Science, Stephen G. Brush discusses this question, as it relates to the development of science throughout the last century. Answering this question requires both a philosophically and historically scientific approach, and Brush blends the two in order to take a close look at how scientific methodology has developed. Several cases from the history of modern physical and biological science are examined, including Mendeleev's Periodic Law, Kekule's structure for benzene, the light-quantum hypothesis, quantum mechanics, chromosome theory, and natural selection. In general it is found that theories are accepted for a combination of successful predictions and better explanations of old facts. Making 20th Century Science is a large-scale historical look at the implementation of the scientific method, and how scientific theories come to be accepted.
About the author
Stephen G. Brush studied chemistry and physics (at Harvard and Oxford) and did research in theoretical physics at the Lawrence Livermore Laboratory. His group at Livermore showed that a gas of electrons (ignoring quantum effects) could condense to a solid at low temperatures and high densities. Inspired by a graduate seminar with Thomas Kuhn at Harvard, he also conducted research in history of science, and switched to that field full-time in 1968. He has published historical works on the kinetic theory of gases, planetary physics, and other topics.
