Physics Today, 1950
Until recently astronomy was restricted to the visual band of the electromagnetic spectrum, and to wavelengths near to the visual band. Our immense store of astronomical knowledge has been obtained from observations made in a band of about four octaves of the spectrum, although measuring techniques are available for about forty octaves.
