Physicists and astronomy—Will you join the dance?

NOV 01, 1981
Observational discovery comes on the heels of technological innovation, giving physics an increasingly dominant role in astronomy

Twenty‐five years ago when I was a graduate student in physics, I was drafted into the Army and sent to Eniwetok in the Marshall Islands. There was plenty of spare reading time for an army private on this tiny atoll, and I had taken along a paperback copy of Fred Hoyle’s Frontiers of Astronomy. Hoyle made astronomy exciting and I began to wonder whether I might find a way to enter the field.

    I am indebted to J. R. Pierce for forwarding to me a copy of a letter to him by David C. Hogg, dated 3 January 1979.
    Hogg, a participant of this project carried out at a 4 GHz frequency, calls attention to the roughly 2.5‐kelvin discrepancy between the measured noise of 17 K and all other calculated sources of noise, roughly 14.5 K, which included the by‐then‐known atmospheric contribution, as well as instrumental noise contributions.
