...measuring wave lengths, one angstrom - 100-millionth of a centimeter. Visible light ranges between 3,900 A. (violet...
...into the green band of the spectrum. If they were bright enough to be seen in color, human eyes would actually see them as green instead of blue. This means that the motion of the nebula has lengthened the wave length of its blue light by more than 800 angstroms (.000003 in.). "It's a tremendous shift," says Dr. Hubble. "In our own stellar system, the average shift is only a fraction of one angstrom...

Excluding the sun, there is no star known nearer than three thousand million million million million Angstroms. (One Angstrom = .00000001 centimetre...
Last week plump-cheeked Dr. Zworykin announced that his iconoscope was ready for use as the "eye" of a powerful ultramicroscope. Its field of operation extends on both sides of the visible light spectrum -up to 10,000 angstrom units on the infra-red range, down to 1,000 on the ultra-violet.* This point on the ultraviolet side is 2,000 units lower than in other ultramicroscopes. If organisms never seen by human eye do exist in the filtrable viruses of common colds and infantile paralysis, they might be detected by light of such short wavelength. Light of longer...
