Electron Microscope Advances INSTRUMENT DEVELOPED BY RCA LABORATORIES. DOING IMPORTANT WAR WORK, BRINGS ABOUT SUDDEN SPURT IN PROGRESS OF SCIENCE: NEW DESK-SIZE MODEL ANNOUNCED. By M. Charles Banca RCA Victor Division, Radio Corporafion of America IN 1942, the RCA Electron Micro- scope's usefulness to science in general and to the war effort in particular was preatly increased. The instrument itself was substan- tially improved in design and oper- ational simplicity, and the tech- nique of applying it to the varied problems of scientific research was considerably advanced. So great is the knowledge-gather- ing potentiality of this new tool of the research worker — an instru- ment that penetrates far into the ultra-microscopic mysteries of na- ture—that Dr. V. K. Zworykin, As- sociate Director, RCA Laboratories at Princeton. N. .J., declared re- cently that it already has brought about a sudden acceleration in the progress of science. At present, the RCA Electron Microscope is rated at from 50 to 100 times more powerful than the best light microscope. There is rea- son to believe, according to Dr. Zworykin. under whose supervision the microscope was developed, that — eventually — further improve- ments in electron microscope lenses will extend this ratio to something liks 1.000 to 1. When these improvements occur, some time in the future, atoms and molecules and the more intimate structures of large molecules and viruses will become visible to re- search workers. The transition be- tween the realms of living and non- living can be closely observed. Fur- thermore, the gap between the elemental building blocks of matter and the gross structures of every day life will then be completely filled. Meanwhile, research is going for- ward in more than two score lab- oratories with the standard RCA Electron Microscope introduced two years ago. Scientists agree that their new-found ability to resolve fRADIO AGE 15]
