...Breaks." Lawrence conceived the basic idea of the cyclotron in 1929 when he read a paper by an obscure German on the behavior of ions in a magnetic field. Next year he and three co-workers -Niels Edlefsen, M. Stanley Livingston and David Sloan-built the first cyclotron with a tank six inches across and a small magnet. It worked, but Lawrence pined for a bigger magnet...
When Dr. Leonard Fuller, head of electrical engineering at the university, heard of this he asked Lawrence how an 85-ton magnet would suit him. Lawrence gasped. Dr. Fuller also happened to be vice-president of Federal Telegraph Co., which had built four 85-ton magnets for round-the-world radio transmission during the War. Peace came before this particular magnet could be shipped to China and ever since it had lain idle at Palo Alto. Dr. Fuller and Dr. Lawrence jumped into an automobile and roared down to Palo Alto. Soon the big magnet was installed at Berkeley...
...have also created a small trace of Radium E-not a temporarily radioactive substance but actual radium. The Lawrence cyclotron technique has in the past five years come to be recognized as the most efficient atom-smashing device in the world. Eleven cyclotrons are either in operation or being built in the U. S., one in Canada, eleven in Europe and the Orient. And many of these projects are directed or staffed by men who learned their cyclotron technique as research fellows under Ernest Lawrence at Berkeley...
...favorites as Millet's Man With a Hoe, such modern equivalents of September Morn as Duchamp's Nude Descending the Stairs. So great a glut of masterpieces overtaxed the capacity of the Art Association's gallery (an annex to the Town House on Wilshire Boulevard, originally built for San Francisco's Gumps). The pictures have to be shown in two shifts: Old Masters the first month, Modern Masters the second...

Pilots who fail in flight tests must accumulate 15 additional hours flying time before presenting themselves for reexamination. No private pilot may ply for hire. Stunting near airways, airports or built-up areas is forbidden...
