Died. Alfred Schild, 55, founder of the Center for Relativity Theory at the University of Texas whose work advanced understanding of such concepts as the formation of galaxies, alternative theories of gravitation, and quantum mechanics; of an apparent heart attack; in Downers Grove...
Smitty's evolution into the lord (or lady) of the cell does not work as well. But the blame does not go to George Elliot, whose only problem is a bit of stiffness and hesitancy in his delivery. The offender is the script, which tries to squeeze two quantum leaps in Smitty's development into two short acts. Initially, Elliot plays Smitty as a naive, slow-witted, very unhip rookie whose first revelation to the cell is that he plans to learn advanced auto mechanics while behind bars. Then suddenly Smitty becomes a sensitive, loyal friend to Mona. And finally...
Here a short digression is necessary. Modern quantum mechanics describes the forces between particles in terms of other, "mediating" particles. The mediating particle of gravity is called the graviton. The mediating particle of the electromagnetic force is called the photon. And the mediating particle of the "strong" force, proposed in 1934 by the Japanese physicist Hideki Yukawa, is called the "pion...
...Steven Weinberg, who is now Higgins Professor of Physics, and Gary Feinberg, now a professor of physics at Cornell. "We learned a great deal by talking and competing with one another. We'd ride the subway to school together. On the way, one of us would say something like 'Quantum mechanics isn't so hard--I learned it last night,' and then explain whatever he'd read," Glashow said. Not to be outdone, someone else would read about another topic that evening and explain it the following morning. "In this way, we certainly learned the language of physics, although nothing...
...contemporary physicists may eventually render physics a "complete" science in the same way that he considers chemistry a complete science, lacking any "interesting" questions. He laments the lack of great contradictions such as those evident in early 20th century physics. From such contradictions the theory of relativity and quantum mechanics grew. In the absence of such contradictions, physics proceeds too smoothly, Glashow reasons, and becomes less interesting...
