According to Livingston, the electron accelerator is not properly an "accelerator" in the normal sense of the word. An experiment may start with electrons at .99 the speed of light and increase the velocity to .99999 the speed of light--not too great a change in percentage terms. What does...

Meanwhile, the mass undergoes a similar increase: the rest mass of a proton is 1800 times as great as that of an electron; by the end of an accelerator experiment, says Livingston, an electron may become "over 6 times as heavy as a proton." In other words, the mass of...

The chief difference between the cyclotron and the Electron Accelerator, according to Preston, aside from the obvious fact that the former works with protons and the latter with electrons, is one of method. In the cyclotron the protons are subjected to a constant magnetic field and spiral out in ever...

...acceleration process in the cyclotron, the beam is directed into an experimental area. There are, however, no serious problems here of deflecting the particles: once the spiraling beam reaches the outer limit of the cyclotron chamber, it can be made to fly off on a tangential line into the experimental area. A typical experiment, Preston says, might involve a beam hitting a target of some element, perhaps carbon. Counters would be set up at various angles to the beam at the point of collision, and the data thus obtained--used with the laws of momentum--might give important information...

With many a TV set, viewers are still subject to double vision. Now both NBC and ABC are trying to add double sound. After a test run in seven cities, Lawrence Welk's Wednesday show (ABC) was broadcast nationwide in stereo, i.e., two different mikes feeding the schmalz into...
