Robert Hofstadter

Died 17 Nov 1990 at age 75 (born 5 Feb 1915).American scientist who was a joint recipient of the Nobel Prize for Physics in 1961 for his investigations in which he measured the sizes of the neutron and proton in the nuclei of atoms. He revealed the hitherto unknown structure of these particles and helped create an identifying order for subatomic particles. He also correctly predicted the existence of the omega-meson and rho-meson. He also studied controlled nuclear fission. Hofstadter was one of the driving forces behind the creation of the Stanford Linear Accelerator. He also made substantial contributions to gamma ray spectroscopy, leading to the use of radioactive tracers to locate tumors and other disorders. (He shared the prize with Rudolf Ludwig Mössbauer of Germany.)

The Password Is

I was in a couple’s home trying to fix their Internet connection. The husband called out to his wife in the other room for the computer password. “Start with a capital S, then 123,” she shouted back.
We tried S123 several times, but it didn’t work. So we called the wife in. As she input the password, she muttered, “I really don’t know what’s so difficult about typing Start123.”
