Daughter: My fiancé said I could have whatever I wanted to be inscribed on his wedding ring. What should I put?
Mother: Put what I put on your father's wedding ring.
Daughter: What does it say. I've never seen daddy with it off.
Mother: Yes. It's worked very well over the years. It says, 'Put it back on!'
Ejnar HertzsprungDied 21 Oct 1967 at age 94 (born 8 Oct 1873). Danish astronomer who classified types of stars by relating their surface temperature (or colour) to their absolute brightness. A few years later Henry Russell illustrated this relationship graphically in what is now known as the Hertzsprung-Russell diagram, which has become fundamental to the study of stellar evolution. In 1913 he established the luminosity scale of Cepheid variable stars. |
