ABSTRACT
Historians tend to put the history of science in a compartment at the margin of 'real' history. The habit of historians has been to include the seventeenth-century scientific revolution in physics and astronomy in their European world history texts but to ignore the multiple scientific breakthroughs of the twentieth century. After the marriage of science and technology people in both areas interacted to produce new investigative technologies. In the early twentieth century geologists and paleontologists were familiar with many anomalous facts. Many geologists rejected Wegener's idea, in part because he was a meteorologist and had no credentials in geology. Geneticists have also revolutionized their discipline. Knowledge of genetics began to grow in 1900, when English-speaking scientists became interested in the work of the late Austrian monk Gregor Mendel. Now scientists are studying the genetics and biochemistry of the brain. The most radical changes have occurred in nuclear physics, astronomy, geology, biochemistry, and genetics.
