Relativistic astrophysics—A report on the Second Texas Symposium

Scientists of 1965 see the universe with diverse eyes. They look with the two‐hundred‐inch pyrex mirror on top of Mount Palomar, with a hundred thousand gallons of cleaning fluid buried more than a mile underground, with scintillation counters flying in rockets and satellites, with a retina covering several square miles of the New Mexico desert at Volcano Ranch, with a steel bowl two hundred and ten feet across at Parkes in Australia, and with a gently swinging aluminum bar in Maryland, waiting patiently for the tremor of a gravitational wave.
