...institute's ultramodern equipment, Director John R. Green is proudest of the massive electron microscope. Magnifying 200,000 times, it can photograph bits of matter as small as a brain cell. "We can study changes in single cells in tumors and changes due to aging," says Dr. Green. "We see this machine as ten tons of hope...
...find rather easily, in fact, that Eddington's absolute constant of 137 began as 136. Eddington added a unit when that value became inconsistent with better experimental values of the electron charge and the speed of light. Max Born's Experiment and The-Physics gently dissects Eddington under an aegis that most critics want to share: evaluation of what seems reasonable and what seems unreasonable. I have the feeling that Newman, with his long experience mathematics, could also have something interesting to say about Eddington's attempt to fit the constants of nature to a Procrustean bed of positive integers...
...treated his chemical broth to moderate heat, pressure and other influences that were probably felt in the ancient ocean. Then he analyzed the product and found that it contained a simple nucleic acid. It met all chemical tests, and when its giant molecules were examined under a powerful electron microscope they showed evidence of the twisted, ropelike structure that is characteristic of natural nucleic acids...
...experiments will take place in huge underground experimental hall. The hall is 100 by 300 feet--the size of a football field--and is located at a tangent to the main accelerator ring. It is in this room that the electron pulses emerge to be directed at various targets...
This accelerator will overcome the most serious objection to a circular machine: the tremendous quantity of energy that is radiated as the electron revolves around the track. For a fixed orbit radius, the radiation losses increase with the fourth power of the particle energy. Eventually, the point is reached where most of the accelerating energy is lost immediately as radiation...
