RPC History 4 Lesson 95

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!
