In the 1640s, Pascal invented the syringe and the hydraulic press. These came about through his investigations into barometric pressure. Another of his inventions was the roulette machine. This invention came about by accident while he was trying to invent a perpetual-motion machine that could generate energy.

Blaise Pascal also made several contributions to the fields of physics, mathematics and philosophy. In mathematics he came up with what is now known as Pascal’s triangle. The triangle is formed by numbers called binomial coefficients. Each number is the sum of the two numbers directly above it. Pascal presented this information in written form in 1653.

In 1654 he formulated a probability theory. The idea behind the mathematical theory came about owing to his desire to help a friend who had questions on gambling.

In physical sciences, Pascal proved that atmospheric pressure could be measured using real weights. He also discovered that vacuums did exist, a theory that created conflict between him and other well-known and respected scientists, such as Descartes.
