Ptolemy made his first star observation. This encouraged him to start career as an astronomer.
-A.C. -
This geometric evidence was explaining how Ptolemy thought the universe worked. More specificly the sun, moon and stars.
-A.C. -
Ptolemy finished his first world map. It wasn't what we know as mordern day world but was on a curved globe. Later in 1492 Christopher Columbus used this map on his expedition.
-A.C. -
The Almagest is a book of astronmy and Ptolemy's observation of the universe. This book helped people learn about our universe or at least about what we thought it as like at the time.

In 1491-1495 copernicus attended Krakow University for a degree in astronomy and geography.
-JWH -
Over his life he wrote a total of three book. The first was "de revelutionibus orbium coelestium".The second was "on the revelutions".The last one was "on the revelutions of heavenly spheres

In 1514 copernicus created the heliocentric theory that states everything in the universe revolves around the sun.
JWH -
He worked to combine the Geometrical benefits of the benefits of the Copernican system with the benefits of the Ptolemaic system.

Tycho Brahe discovers the star named SN. He observed that the star is a fixed star. He also observed that the star was farther than all the planets in the atmosphere.

Tycho Brahe predicted a lunar eclipse on December 15th, 1573. He observed and found the perigee of the sun. Which is when the moon, earth, and sun are all in line.

Tycho built an observatory called Urraniborg in Huen. He used it for his work and discoveries. He also used it to help Johannes Kepler with his Kepler's Law of Planetary Motion.

Galieo works on the theory of motion and discovers many things about velocity, mass, motion, and speed. One example is he dropped a big and a small ball (motion).
-KJ -
He invints a pump driven by horses, and a year later he recived a patent from the Ventain Senate about his new invention.(A patent is a legal instrument that is published by a monarch or president).

Kepler left Tubingen and went to Graz. There he became an astronomy and math teacher.
-L.B. -
He dicovers a new theory wich is named "theory of uniform Acceleration wich in Grms that all bodies regardless of weight fall at an equal rate.
KJ -
Kepler invent's three laws of planetary motion.
1. the orbit of every planet is an ellipse with the sun at one of two foci. 2. a line joining a planet and the sun sweeps out equal areas during equal intervals of timen 3. The square of the orbital period of a planet is directly proportional to the cube of the semi-major axis of it's orbit

Johannes kepler improved a version of Galileo's version of the refracting telescope. He called it the Keplerian telescope.

Isaac Newton invents the reflecting telescope.
