• In 1641 Pascal published his work called Essay on Conic Sections. This work affected the field of projective geometry- it discussed the transfer of a 3D object onto a 2D field. 
• Pascaline. This calculator was able to add, subtract, multiply, and divide. The Pascaline never became popular and lasted less than a year in production. However, his invention led to computer scientist Nicklaus Wirth naming a computer language after Pascal.
  
• In the early 1650s, Pascal was focused on perpetual motion. He wanted to create something that created more energy than it used. He created a roulette machine, roulette being a word for “little wheel” in French.
  
• In 1653, Pascal invented the arithmetical triangle.
  
• Starting in 1654, Pascal teamed up with mathematician Pierre de Fermat and made a discovery that became the basis of probability. Through his own experiments he proved nothing happens randomly- there is a fixed probability for everything.
  
• Pascal studied a lot about binomial coefficients, which later influenced the discoveries made by Sir Isaac Newton.

Pascal passed in 1662 in Paris, France. He died of a malignant stomach tumor that had reached his brain. Hundreds of years later in the 1970s his name was given to the unit of pressure that refers to a single newton acting on a square-meter of surface- the Pascal unit.
