Salomon Bochner

Born 20 Aug 1899; died 2 May 1982 at age 82. Salomon Chaim Bochner was a Galician-American mathematician and educator who is remembered for his Bochner theorem of positive-definite functions and the Bochner integral. In the later development of abstract Fourier analysis, the Bochner theorem was basic to the theory of distributions. He started his academic career in Germany. In 1933, as a Jew, with the rise of the Nazism, he fled to the U.S., where he joined the faculty at Princeton. In addition to his life-long interest in harmonic analysis, in his prolific writings, Bochner also contributed significantly to complex analysis, differential geometry, probability and other pioneering work in pure mathematics. In his later years, he turned almost exclusively to the history and philosophy of science. His best-known book, The Role of Mathematics in the Rise of Science (1966), was translated into many languages.«

Greeting Card Quest

A little boy had been pawing over the stock of greeting cards at a stationery store.
After a few minutes the clerk became curious and asked, "Just what is it you're looking for, sonny? Birthday greeting? Message to a sick friend? Anniversary congratulations to your mom and dad?"
The boy shook his head, "No."
"Then what kind of card is it that you want?" asked the clerk.
The boy answered wistfully, "Got anything in the line of blank report cards?"
