I learned about three inventions and one inventor. The three inventions are Mersenne’s Law, Cartesian Coordinates, and Mechanical Calculator. The inventor’s name is Blaise Pascal. The first invention I learned is Mersenne’s Law. His laws tell how to tune a string instrument. Mersenne established the science of acoustics. The second invention I learned about is Cartesian Coordinates.  His Coordinate System allows the plotting of geometric shapes in algebraic notation 2x + 2x = 4. The Cartesian Coordinate System was vital for calculus. The third invention I learned about is the Mechanical Calculator. A mechanical calculator is a mechanical device used to automatically perform the basic operations of arithmetic. The first commercial success arose in 1851 and they were produced until the 1970s. Lastly, I learned about Blaise Pascal. He investigated the concept of the vacuum and he got involved with experiments associated with the invention of the barometer. He was an important contributor to science and his law produced important inventions. 

I learned about three inventors and one invention. The inventors’ names are Johannes Kepler, Galileo Galilei, and John Napier. The invention is the slide rule. First, I learned about Johannes Kepler. He viewed the universe as an analogy of the Trinity. He developed a problem that required a new tool to solve, which required calculus to solve it. Kepler’s work inspired Newton. Second, I learned about Galileo Galilei. He was a pioneer and also controversial. He improved the telescope in 1609 and he applied mathematics to physics. He advanced the scientific method. Third, I learned about the slide rule. It became a symbol for the engineering profession by the 1950. The slide rule made it possible to do engineering. Lastly, I learned about John Napier. His greatest achievement was inventing the logarithm. He is best known for the King James version of the bible.

I learned about three inventions and one inventor this week. The inventions are the compound microscope, the newspaper, and the telescope. The inventor’s name is Wiliam Gilbert. First, I learned about the compound microscope. Compound microscopes generate 1000 xt magnification. People use it to see blood cells in t-rex bones. Second, I learned about Wiliam Gilbert and his life. He resurrected scientific interest in magnetism and introduced the concept of attractive force. His book impacted the course of history. Third, I learned about the newspaper. Newspapers quickly transmit information. They also captured the universities, the churches and the courts. Finally, I learned about the telescope. They are used to magnify far away objects and improve our ability to see into the cosmos. They allow us to see waves invisible to our eyes.
