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.

Quotation of the day
From August Crelle
The real purpose of mathematics is to be the means to illuminate reason and to exercise spiritual forces.
