Mathematicians Of The Day
11th March
On this day in 1574, using his various instruments, Egnation Danti detected the 11 day error in the calendar when he calculated the vernal equinox to have fallen on 11 March rather than on 22 March as it should for the calendar to be in step with the seasons. From that time on Danti became a leading figure in pressing for calendar reform.
The postage stamp of one of today's mathematicians at THIS LINK was issued in 1958.

Quotation of the day
From Mary Everest Boole
The mathematical formulae which some people speak of contemptuously as "dry" are in reality as beautiful as microscopes, or any other well-adjusted and well-finished machinery intended to extend the scope of men's powers; and as for mathematical ideas themselves, they are as grand as any expressed in poetry.
