New broom...

A woman was waiting in the check-out line at a shopping center. Her basket was filled with a mop and broom and other cleaning supplies. By her actions and deep sighs, it was obvious that she was in a hurry and not happy about the slowness of the line.

When the cashier called for yet another price check on a box of soap, the woman remarked, indignantly, "Well, at this rate, I'll be lucky to get out of here and home before Christmas!"

"Don't worry, Ma'am," replied the clerk. "With all that wind kicking up over there and that brand new broom you have in your basket, you'll be home in no time."

Otto Struve

Born 12 Aug 1897; died 6 Apr 1963 at age 65. Russian-American astronomer who was a fourth generation astronomer, the great-grandson of Friedrich Struve. He made detailed spectroscopic investigations of stars, especially close binaries and peculiar stars, the interstellar medium (where he discovered H II regions), and gaseous nebulae. He contributed to the understanding of the broadening of spectral lines due to stellar rotation, electric fields, and turbulence and worked to separate these effects from each other and from chemical abundances. He was a pioneer in the study of mass transfer in closely interacting binary stars. Struve emigrated to the USA (1921) and joined the Yerkes Observatory, Wisconsin, becoming its director in 1932.«
