Mathematicians Of The Day
23rd November
On this day in 1823, Janos Bolyai wrote to his father, I have made such wonderful discoveries that I am myself lost in astonishment. He was referring to his discovery of non-Euclidean geometry that was published in 1833.

Quotation of the day
From John Wallis
Dr. Wallis defines mechanicks to be the geometry of motion, a mathematical science, which shews the effects of powers, or moving forces, so far as they are applied to engines, and demonstrates the laws of motion.
