||Gabriel Andrew Dirac (b. 13 March 1925) was a mathematician who mainly worked in graph theory. He stated a sufficient condition for a graph to contain a Hamiltonian circuit. In 1951 he conjectured that n points in the plane, not all collinear, must span at least [n/2] two-point lines, where [x] is the largest integer not exceeding x. This conjecture is still open. | |||

1763: Mathematician Maria Gaetana Agnesi uses Gnomon algorithm techniques to fight crimes against mathematical constants.
1764: Charles Grey, 2nd Earl Grey born. His government will see the abolition of slavery in the British Empire.
1877: Children reprogram Jacquard loom to compute new family of Gnomon algorithm functions.
Mathematician Melvin Dresher (Dreszer) born. He will contribute to game theory, co-developing the game theoretical model of cooperation and conflict known as the Prisoner's dilemma.
2016: Philosopher, mathematician, and computer scientist Hilary Putnam dies. He argued for the reality of mathematical entities, later espousing the view that mathematics is not purely logical, but "quasi-empirical".
