Jones came into the office an hour late for the third time in one week and found the boss waiting for him.
"What's the story this time, Jones?" he asked sarcastically. "Let's hear a good excuse for a change."
Jones sighed, "Everything went wrong this morning, Boss. The wife decided to drive me to the station. She got ready in ten minutes, but then the drawbridge got stuck. Rather than let you down, I swam across the river — look, my suit's still damp — ran out to the airport, got a ride on Mr. Thompson's helicopter, landed on top of Radio City Music Hall, and was carried here piggyback by one of the Rockettes."
"You'll have to do better than that, Jones," said the boss, obviously disappointed. "No woman can get ready in ten minutes."

Shiing-shen Chern

Died 3 Dec 2004 at age 93 (born 26 Oct 1911). Chinese-American mathematician and educator whose researches in differential geometry include the development of the Chern characteristic classes in fibre spaces, which play a major role in mathematics and in mathematical physics. “When Chern was working on differential geometry in the 1940s, this area of mathematics was at a low point. Global differential geometry was only beginning, even Morse theory was understood and used by a very small number of people. Today, differential geometry is a major subject in mathematics and a large share of the credit for this transformation goes to Professor Chern.”- C N Yang, quoted from the book, Chern, a great geometer of the twentieth century. (1992)
