Merenne’s Laws

Mersenne was born in 1558 in France and corresponded with prominent scholars after 1620. He was interested in protecting against occult influences. Merenne pursued the mathematical basis of acoustics without getting confused. Audible sound vibrates at a certain frequency. Mersenne’s laws tell how to tune a string instrument. Longer strings play lower notes, tighter strings play higher notes and heavier strings play lower notes. Mersenn gets the credit even though he didn’t come up with the idea. Galileo had the idea but didn’t think they could be proven but since Mersenne published his findings he got the credit. He spread them using the large network he had built over time. 

Cartesian Coordinates 

Descartes was born in France in 1596. He was educated by jesuits.  He joined the Duthch army and developed a thirst to systematize mathematical physics. He was a chistian who believed our reason was founded on God’s existence. His coordinate system was published in 1637. Cartesian coordinates let you graph coordinates on a plane. Descartes invented the modern algebraic notation. His coordinate system allows the platting of geometric shapes in algebraic notation: x2+y2=4 (circle.) Cartesian coordinates united algebra and geometry. Electrical quantities can be represented. Mathematics are man-made. Symbols and rules that incredibly conrespond. Descartes wasn’t the only person to invent the idea but the credit goes to Descartes because he published the idea. Mersenne’s scholarly not work helped spread Descartes ideas. Descartes’ system was initially a single axis. The Duch added the second axis when translating the book. 

Mechanical Calculator

Blaise pascal was born in France in 1623. His family’s wealth suffered ups and downs. His father became a tax collector for the king of France. Paslal observed the repetitive calculations he had to do. Pascal wanted to alleviate his dad’s burdes. He designed a special “carry” mechanism. His sautor linked wheels together automatically as one turned over from 9 to 0. It consisted of input wheels and display windows. Pascal’s machine wasn’t the first built but he gets the credit.

Blaise Pascal

  Blaise pascal was born in France in 1623 Pascal was a child prodigy gifted in math. His father took him to Mersenne’s meeting. He invented the mechanical calculator to help his father. He experienced a kind of religious conversion when he was 23. Pascal is best known for pascal’s law. He investigated the concept of the vacuum. He got involved with experiments associated with the invention of the barometer. Pascal laid the foundations of probabilistic theory. He wrote influential books. Pascal’s influence spread throughout Mersenne’s network. He died when he was just 39
