In retrospect

On a Saturday evening, I was watching a film with harsh organ music on the TV when I screamed, "Nooo! Do not enter that church, you stupid man!"

My wife came running from the kitchen and asked, "What are you watching?"

I replied, "Video of our marriage!"

Thomas Gold

Born 22 May 1920; died 22 Jun 2004 at age 84. Austrian-British-American astronomer known for a steady-state theory of the universe, explaining pulsars, and naming the magnetosphere. In 1948, as a graduate student at Cambridge, he (together with Hermann Bondi and Fred Hoyle) proposed that, a continuous creation of matter in space is gradually forming new galaxies, maintaining the average number of galaxies in any part of the universe, despite its expansion. This is not accepted, as there is more evidence for the Big Bang theory. In 1967, Gold presented his theory on the nature of pulsars (objects in deep space that produce regularly pulsing radio waves). He suggested that they were rotating neutron stars - tiny, extraordinarily massive stars - which emit waves as they spin.
