The life of Johannes Kepler (dec 27, 1571 – nov 15, 1630)
Description:
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.
