Solutions were offered by , , ,and others; Pascal, under the pseudonym Amos Dettonville, published hisown solution. Controversy and heated argument followed after Pascalannounced himself the winner.

In addition to the childhood marvels previously mentioned, Pascalcontinued to influence mathematics throughout his life. In 1653, Pascalwrote his ("Treatise on the Arithmetical Triangle") in which he described a convenient tabular presentation for , now called . In 1654, prompted by a friend interested in gambling problems, he corresponded with on the subject, and from that collaboration was born the mathematical theory of . The friend was the ,and the specific problem was that of two players who want to finish agame early and, given the current circumstances of the game, want to , based on the chance each has of winning the game from that point. From this discussion, the notion of was introduced. Pascal later (in the ) used a probabilistic argument, , to justify belief in and a virtuous life.

Pascal was credited with the invention of the barometer and certain mathematical formulations which "heralded the invention of the differential calculus." It was, in 1654, that Pascal was to have a mental crises and broke completely with his circle, and, claiming to have had religious revelations, went to join and live with his sister in the religious community in which she had belonged.

By 1646, Pascal had learned of 's experimentation with .Having replicated an experiment which involved placing a tube filledwith mercury upside down in a bowl of mercury, Pascal questioned whatforce kept some mercury in the tube and what filled the space above themercury in the tube. At the time, most scientists contended that,rather than a ,some invisible matter was present. This was based on the Aristoteliannotion that creation was a thing of substance, whether visible orinvisible; and this substance was forever in motion. Furthermore,"Everything that is in motion must be moved by something," declared.^{}Therefore, to the Aristotelian trained scientists of Pascal's time, avacuum was an impossibility. How so? As proof it was pointed out:
