RPC History Lesson 105

Hello! Here is what Mr.Livingston wanted me to do today: Summarize each of the inventions you studied this week and how they impacted history.

So here is the essay!

I learned about Johannes Kepler, Galileo Galilei, The Slide Rule, and John Napier.

Johannes Kepler was born on December 27, 1571, in Weil der Stadt, Württemberg, in the Holy Roman Empire of German Nationality. He was a sickly child and his parents were poor. But his evident intelligence earned him a scholarship to the University of Tübingen to study for the Lutheran ministry. He became very interested in astronomy when his professor encouraged him.

Galileo Galilei was born in Pisa in 1564, the first of six children of Vincenzo Galilei, a musician and scholar. In 1581 he entered the University of Pisa at age 16 to study medicine, but was soon sidetracked by mathematics. He left without finishing his degree. Galileo was best known for all of his time spent through a telescope that caused him to make plenty of discoveries. Like he discovered the moons orbiting Jupiter.

The slide rule was invented around 1620–1630, shortly after John Napier’s publication of the concept of the logarithm. In 1620 Edmund Gunter of Oxford developed a calculating device with a single logarithmic scale; with additional measuring tools it could be used to multiply and divide.

John Napier, Napier also spelled Neper, born 1550, Merchiston Castle, near Edinburgh, Scotland died April 4, 1617, Merchiston Castle, Scottish mathematician and theological writer who originated the concept of logarithms as a mathematical device to aid in calculations. logarithms also spared a lot of time to people who used this invention to multiply.

That’s it!
