The Principia mathematica of See also:Sir See also:Isaac See also:Newton, which See also:chance threw in his way, caused him to prosecute his studies with vigour, and he soon became distinguished among first-See also:rate mathematicians .

But he has been more generally known by his See also:Doctrine of Chances, or Method of Calculating the Probabilities of Events at See also:Play . This See also:work was first printed in 1618, in 4to, and dedicated to Sir Isaac Newton . It was reprinted in 1738, with See also:great alterations and improvements; and a third edition was afterwards published with additions in 1756 .
