THE INVENTIONS OF BLAISE PASCAL Blaise Pascal was a French mathematician, physicist, inventor, writer and Catholic philosopher. A child prodigy many might call him, he was a very intellectual man even from a young age. He was born on June 19, 1623 in Clermont-Ferrand, France. Blaise was educated by his father, a Tax Collector in Rouen. As a teenager and throughout his life he has made many advances in the fields of math and science especially in the fields of pressure and probability. Pascal was a very important figure in the history and science and without it many things we that have helped our society would not be here. PASCALINE

The Pascaline was one of Blaise’s more famous inventions. It was an early version of a calculator that he invented to help his father out with his job as a tax collector.The Pascaline had 8 moveable dials that could all add up to eight long sums and they used the base of ten. So pretty much how it worked was that you could move the first dial up 9 times and on the tenth time the second dial would move up one time and so forth. Each dial represented something different from tens to hundreds to thousands and so on. The format than this early calculator was built in was the format that helped develop other calculators until what we have today. So without this we would have never had calculators or anything that requires a calculator such as many engineering jobs, that’s how influential it is. Roulette Machine

In the 17th century Pascal made a primitive version of the roulette. It looked like an average roulette machine from nowadays with a few appearance differences. The way he created them was in his search for his perpetual motion machine. He was trying to build a machine that never stopped moving and ended with a roulette machine for one of his versions of the machine. The machine was what he had wanted as it eventually stopped moving but we now have put the machine to good purpose. The main purpose that we use it for nowadays is for a gambling game. This may not be such an important use for it but without Pascal many fans would not have the game they spend hours having fun with.

Wrist Watch

Pascal was one of the first people to use wrist watches; it was very primitive and not as technological. The watch was pretty much just his pocket watch attached to a string and tied around his wrist. He did this so it would be simpler to look at time and also much faster. Although it wasn’t so advanced it inspired a lot of people to make their own wrist watches. In our modern day the wrist watch is a very important part of many people’s lives and has revolutionized the convenience of reading time for humans.

Pressure

Pascal also made many advances in the field of studying pressure. He researched pressure a lot and made many experiments to discover more about it. His helped clarify topics and ideas with pressure and vacuum. Pascal’s most lasting effect on the both fields was a unit of measuring pressure known as Pascals. A Pascal is equal to 101,325 which is another measure of pressure. Pascals are still widely used more specifically Kilopascals. The unit of Pascals has helped many scientists quantify the measurement of pressure in a different way and has helped many fields of science.

FLUIDS

Along with studies with pressure he also helped with studies of fluid. Pascal even came up with his own law now called Pascal’s Law. Pascal Law states "pressure exerted anywhere in a confined incompressible fluid is transmitted equally in all directions throughout the fluid such that the pressure ratio (initial difference) remains same.” This is pretty much states that if you apply force into a confined fluid the force will be spread evenly throughout the whole liquid not just in one area. For example if you fill a balloon with water it will fill up the ballon evenly on all sides not just on corner of the balloon. This law has helped in the development of many other inventions by Pascal, one being the invention of the syringe. The syringes use this principle to suck up liquids and the same principle to throw them back out. Syringes have been really helpful for us, especially with all the diseases around in the world. Some may be painful but it is for a better health. Syringes provide a quick injection of a certain vaccine which helps spread health to many people. Math

In math he made many advances in the theory of probability. Probability is a branch of math that focused around random phenomenon and how to predict it. Pascal along with other great minds put in a lot of research toward this theory and have contributed a lot to it most of which is now taught at schools and universities. Many predictions and statistics have come from the fundamentals that he researched which now have built up many businesses.

These theories have revolutionized math especially with his invention of Pascal’s triangle. This triangle is pretty much an array of binomial coefficients that have helped out mathematicians over the years. The way the triangle works is that it starts off with 1 down two sides. Then numbers next to each other add up to form numbers below them and so on. I myself really enjoy math and I am really appreciative of his contributions and I am sure many scientists and mathematicians do too.
