...theory was one of history's most imaginative and dramatic revisions of our concepts about the universe. It was, said Paul Dirac, the Nobel laureate pioneer of quantum mechanics, "probably the greatest scientific discovery ever made." Max Born, another giant of 20th century physics, called it "the greatest feat of human thinking about nature, the most amazing combination of philosophical penetration, physical intuition and mathematical skill...
Oppenheimer next embarked for his father’s native land of Germany, studying the still-developing field of quantum mechanics alongside future physics giants like Paul Dirac, Max Born, and Werner Heisenberg. But he never acquired the Europeans’ suave ways with womenfolk. Upon returning stateside to teach at Berkeley, Robert earned a small dose of worldwide notoriety for his romantic foibles. He drove a date to a scenic point up on a hill, and after she fell asleep, he whispered that he would walk back home and she should follow in the car. She did not hear...
Einstein continued to work on the quantum idea into the 1920s but was deeply disturbed by the work of Werner Heisenberg in Copenhagen, Paul Dirac in Cambridge and Erwin Schrodinger in Zurich, who developed a new picture of reality called quantum mechanics. No longer did tiny particles have a definite position and speed. On the contrary, the more accurately you determined the particle's position, the less accurately you could determine its speed, and vice versa...

...zero (minus 460° F). Current thus moved through it without resistance, allowing the slightest twitch in the current's flow to be recorded. At 1:53 p.m. on Feb. 14, the magnetic flux in Cabrera's device jumped eight steps, exactly what was expected if a Dirac monopole passed through. Cabrera, a little skeptical, hit his device with a screwdriver to see if that blow too would register a significant reading. It did not. After examining every possible explanation, Cabrera concluded that a monopole had moved through his equipment. "The event is striking," says Cabrera. "We have...
