Mathematicians Of The Day

9th May

On this day in 1831, during a dinner to celebrate his acquittal on a charge of attempting to overthrow the government, Évariste Galois raised his glass and with an open dagger in his hand appeared to make threats against the French king, Louis-Phillipe. The next day Galois was arrested and held in Sainte-Pélagie prison.

Quotation of the day

From Gaspard Monge
Descriptive geometry has two objects: the first is to establish methods to represent on drawing paper which has only two dimensions, -- namely, length and width, -- all solids of nature which have three dimensions, -- length, width, and depth, -- provided, however, that these solids are capable of rigorous definition.
The second object is to furnish means to recognize accordingly an exact description of the forms of solids and to derive thereby all truths which result from their forms and their respective positions.
