Hi, I'm Tyco Brahe. I am Europe's best astronomer!
I discovered 720 stars and charted them. I used huge instruments to calculate the position of the stars and the use of my instrument help others chart stars accurately as well.
I also built Europe's best observatory. Not only was it one of the best observatories but I also proved Copernicus's theory that the sun is the center of the universe.
Hello, my name is Blaise Pascal. I invented what you call the calculator and created the foundation for the probability theory.
I invented what you now call the calculator. It used to be called the Pascaline. Not only the name is different from what it is now, but had a wheel with eight movable parts for dialing. Each part corresponded to a particular digit in a number.
I also created a foundation fro the theory of propability. I was inspired by my desire to help a friend who had some questions about gambling. I realized that events don't happen randomly, but actually depend on what happened just before the event.
