...speed atomic particles or ions. The cyclotron affords a method of achieving these high speeds through a combination of electric and magnetic forces acting on the ions which have their origin at the center of a large vacuum chamber. These forces cause the atomic particles to travel in a spiral, receiving a "push" of many thousand volts at each half revolution...
...Heinz sample counter, fell-or jumped-into Fountain Lake, leaped on the revolving platform in the Glass Center patio for a merry-go-round, scrambled up the rigging of the clipper ship Yankee, exchanged black eyes, rushed across flower beds, awed barkers, frightened monkeys in Jungleland, slid down a spiral staircase in the Street of Tomorrow, wrote their names on every virgin wall, on the base of the Perisphere, and George Washington's feet...
...Tons? Ernest Orlando Lawrence, the jovial University of California physicist who invented the cyclotron (spiral atom-smasher), recently completed a new 220-ton cyclotron, so far the world's biggest, most powerful. Last week he gave a progress report on this monster in operation. With a power input of only 50 kilowatts (more than enough to run a good-sized radio station), he and his crew have obtained beams of 16-million-volt heavy hydrogen particles and 32-million-volt helium particles. With the 32-million-volt beam, new radioactive substances throwing off electrified helium gas have been discovered...
Among the newly discovered objects reported were two spiral nebulae, un-usual in that they possess no concentrated nuclei; and a Magellanic Cloud in the constellation Cetus, a new member of a class of irregularly shaped, conglomerate stellar systems...
...heavy carbon apparatus is a tall glass cylinder with glass spirals inside. Heavy carbon can be separated from light carbon because it dissolves in hydrogen cyanide and sodium cyanide at slightly different rates. When sodium cyanide in water solution runs down the spiral and hydrogen cyanide as a gas flows upward, heavy carbon collects at the top of the apparatus. There were no leaks and the canaries warbled serenely...
