The life of Johannes Kepler (27 Dez 1571 Jahr – 15 Nov 1630 Jahr)

Beschreibung:

His greatest accomplishments included making his laws of planetary motion, which were used by Isaac Newton. These laws include;
1) every planet’s orbit is an ellipse with the Sun at a focus; 2) a line joining the Sun and a planet sweeps out equal areas in equal times; and 3) the square of a planet’s orbital period is proportional to the cube of the semi-major axis of its orbit. We think his greatest discovery would be creating the Keplerian Telescope, because it improved magnification.
