Hello! This Mr.Livinston assigned me to do this: Summarize each of the inventions you studied this week and how they impacted history. Also, explain the most interesting thing you learned this week, and why .

1. The Mercator Projection Map. The Mercator projection was originally developed in 1569 by the Flemish cartographer Gerardus Mercator. At this time, many of Europe’s top cartographers and explorers used elliptical projections derived from Ptolemy’s latitude and longitude grid.
2. Gerardus Mercator. Gerardus Mercator, original name Gerard De Cremer, or Kremer?, (born March 5, 1512, Rupelmonde, Flanders [now in Belgium]—died December 2, 1594, Duisburg, Duchy of Cleve [Germany]), Flemish cartographer whose most important innovation was a map, embodying what was later known as the Mercator projection.
3. Tycho Brahe. Tycho Brahe, (born December 14, 1546, Knudstrup, Scania, Denmark—died October 24, 1601, Prague), Danish astronomer whose work in developing astronomical instruments and in measuring and fixing the positions of stars paved the way for future discoveries.
4. The Backstaff. Backstaff is the name given to any instrument that measures the altitude of the sun by the projection of a shadow. Invented by John Davis in the 16th century, it became a useful tool for navigators at sea. The backstaff was a navigational tool that measured altitude using the sun.

My favorite was probably Gerardus Mercator because his name sound very familiar to my pepere’s name (pepere is grandpa in french). My pepere’s name is Gerard but the adults call him Jerry. My pepere is very funny and always makes jokes. Now pepere and me go to Sudbury (where the big Nickel is) and deliver the Click fork orders for my mom and we always have tons of fun. My mom business is an online farmers market that is basted for north-east of ontario. It’s technically our farms side business that lets us add an S to Dalew FarmS.

That’s it!

Hello! Here is my essay from Mr.Livingston: Summarize each of the inventions you studied this week and how they impacted history. Also, explain the most interesting thing you learned this week, and why.

The four inventors and inventions I learned about this week are: The Heliocentric Theory in lesson 86,
in Lesson 87 I learned about Nicolaus Copernicus,
in Lesson 88I learned about the great Andreas Vesalius,
and in Lesson 89 I probably learned about one of the greatest inventions of all time the pencil.

The Heliocentric Theory. In 1543, Nicolaus Copernicus detailed his radical theory of the Universe in which the Earth, along with the other planets, rotated around the Sun. … Galileo discovered evidence to support Copernicus’ heliocentric theory when he observed four moons in orbit around Jupiter.

Nicolaus Copernicus. Polish astronomer Copernicus is born. On February 19, 1473, Nicolaus Copernicus is born in Torun, a city in north-central Poland on the Vistula River. The father of modern astronomy, he was the first modern European scientist to propose that Earth and other planets revolve around the sun.

Andreas Vesalius. Andreas Vesalius (1514-1564) Andreas Vesalius was born on 31 December 1514 in Brussels, Belgium, then part of the Holy Roman Empire. He came from a family of physicians and both his father and grandfather had served the holy Roman emperor.

The Pencil. The modern pencil was invented in 1795 by Nicholas-Jacques Conte, a scientist serving in the army of Napoleon Bonaparte. The magic material that was so appropriate for the purpose was the form of pure carbon that we call graphite.

That’s it hope you enjoyed!
