Orlov, a prominent high-energy physicist and collaborator with Russian human rights leader Andrei Sakharov, is chief of the unofficial committee which monitors Soviet compliance with the individual civil rights provision in the 1975 Karl Strauch, professor of Physics and one of the signers of the February 18 telegram, said yesterday he hopes concern from so many prominent scientists will encourage Soviet officials to free Orlov and allow him to return to his work...
...look at the marvelously improbable tales of Arthur Conan Doyle and Agatha Christie. What distinguishes Cussler's attempt from a genuinely good mystery a la Holmes or Poirot is the author's singular inability to create any distinctively human characters. Cussler's figures are worse than wooden: the neurotic physicist, dashing American agent, villainous Russian spy and confused but loving heroine are all solid concrete stereotypes that wouldn't even pass muster in a remake of "The Adventures of Superman." And the dialogue, which seems borrowed from a 1952 State Department propaganda pamphlet, doesn't help--one hardly knows whether...
...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...
...attempt to bring some order to the unruly world of hadrons, Murray Gell-Mann, a physicist at the California Institute of Technology, proposed the quark theory. All hadrons, said Gell-Mann in 1963, can be composed of two or three quarks or their anti-particles. Quarks come in three "flavors"--up, down and sideways. Down quarks ('d') have an electric charge of -1/3, up quarks ('u') have charge + 2/3. And then there are sideways quarks ('s'). Sideways quarks are used to make "strange" particles, the ones with the long lifetimes, and are said to have "strangeness" 1. All other...
Finally the story moves to Glashow's contribution, which came in 1964. Motivated by considerations of grace and elegance in theories which combined the electromagnetic force and a force called the "weak force" (to distinguish it from the "strong force"), Glashow and another physicist, James D. Bjorken, postulated an additional flavor of quark, and named it the "charmed" quark. Glashow writes in a New York Times article...
