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?"

Jacques-Salomon Hadamard

Died 17 Oct 1963 at age 97 (born 8 Dec 1865).French mathematician who proved the prime-number theorem (as n approaches infinity, the limit of the ratio of (n) and n/ln n is 1, where (n) is the number of positive prime numbers not greater than n). Conjectured in the 18th century, this theorem was not proved until 1896, when Hadamard and also Charles de la Vallée Poussin, used complex analysis. Hadamard's work includes the theory of integral functions and singularities of functions represented by Taylor series. His work on the partial differential equations of mathematical physics is important. He introduced the concept of a well-posed initial value and boundary value problem. In considering boundary value problems he introduced a generalisation of Green's functions (1932).
