What French mathematician and philosopher, devised roulette while trying to attain perpetual motion, and also invented the hydraulic press and the syringe?
Roulette deflectors, and falls onto the wheel and into one of 37 (single zero French/European style roulette) or 38 (double zero American style roulette) colored and numbered pockets on the wheel. The first form of roulette was devised in 18th century France. Many historians believe Blaise Pascal introduced a primitive form of roulette in the 17th century in his search for a perpetual motion machine. The roulette mechanism is a hybrid of a gaming wheel invented in 1720 and the Italian game Biribi. The game has been played in its present form since as early as 1796 in Paris. An early
Hydraulic press Hydraulic press A hydraulic press is a machine press using a hydraulic cylinder to generate a compressive force. It uses the hydraulic equivalent of a mechanical lever, and was also known as a Bramah press after the inventor, Joseph Bramah, of England. He invented and was issued a patent on this press in 1795. As Bramah (who is also known for his development of the flush toilet) installed toilets, he studied the existing literature on the motion of fluids and put this knowledge into the development of the press. The hydraulic press depends on Pascal's principle-the pressure throughout a closed
