MAGNIFY - CENT!
At research laboratories in New Jersey, U.S.A., the Radio Corporation of America has been developing a microscope which opens up whole new worlds that are invisible to light and which shows promise of extending the boundaries of knowledge in the study of human disease and other fields of research. The instrument works with elec-trons-a stream of electrons directed on to a magnetic field bend in the same way as light bends when directed on to glass lens. Bacteria or other minute particles to be examined can be magnified by 25,000 diameters. The sharpness of definition of the new electron microscope is so great, however, that useful magnification may be increased up to 100,000 diameters by photographic enlargement. Many objects cannot be seen with light because they are much smaller than light waves (shades of Mr. Wells’s Invisible Man’). However, as an electron beam measures only one-one-hundred-thousandth of the wavelength of light, far more intricate research than has hitherto been possible now becomes easy. Yet, as nothing is without its opposite, this instrument to see the smallest things devised by God jis one of the largest microscopes devised by man.
