Sarnoff was born in Uzlian, Russia, in 1891 (the year the electron was christened; he often bragged they were born the same year) and traveled steerage to New York nine years later with his family. Knowing no English, he helped support his family by selling newspapers and with other small jobs. At 15 he bought a telegraph key, learned Morse code and, after being hired as an office boy for the Marconi Wireless Telegraph Co. of America, became a junior operator...
Kohl's experiments initially focused on the electron, a relatively light subatomic particle, determining its temperature to be about 1 million degrees Celsius...
What is most remarkable about the spacecraft is how it gets from place to place. After being launched by an ordinary rocket, DS1 will be pushed through space by an engine that works by firing electrons into atoms of xenon gas, stripping each of an electron and giving the atoms an electric charge--ionizing them. The ions are then accelerated through an electric field and emitted from thrusters at 65,000 m.p.h. Despite that speed, the particles produce little thrust, comparable to the weight of a piece of paper...
...Have you seen the way they're slicing the salami?" asked Simpson, a former Republican senator from Wyoming. "You'll need an electron microscope to discern the slices here...
...textbooks at once. That's evidently what happened last week at a scientific conference in Japan. An international team of 120 physicists reported that the neutrino, a subatomic particle long thought to be utterly without mass, actually weighs in at a tiny fraction of the mass of the electron (until now, the lightest particle known). For elementary-particle physicists, that means their most basic theories will have to be rewritten; for astronomers, it means that the missing "dark matter" believed to pervade the cosmos and far outweigh the visible stars may no longer be missing...
