On 14 March 1964 Richard Feynman, one of the greatest scientific thinkers of the 20th Century, delivered a lecture entitled ‘The Motion of the Planets Around the Sun‘. The talk covered Johannes Kepler’s first law of planetary motion in a way no other lecture has done. For thirty years this remarkable lecture was believed to […]

So planets travel around the Sun in elliptical orbits with the Sun at one focus – Ok, a line from the planet to the Sun sweeps out equal areas in equal times, Gotcha and the square of a planet’s period in years and its distance cubed are proportional. Okey Dokey! But what does it all mean?

Kepler put our feet on the road to modern astronomy. But ask yourself: Why were the planets spaced as they were in order of distance from the Sun? Had God arranged the Universe in accordance with the perfect precepts of geometry? And could we discover a true cosmic harmony designed by the almighty for us, and others to discover?

In 1611, Kepler proposed that the closest sphere packing has a maximum density of pi/(3sqrt(2)) approx 74%), this became known as Kepler conjecture. Sure Buckminster Fuller (1975) claimed to have a proof, but…

The early 17th century was a tumultuous time for scientists in Europe. Explore the process that Johannes Kepler undertook when he formulated his three laws of planetary motion. Kepler’s laws were crucial in the understanding of our solar system dynamics. This video presents the story of Johannes Kepler and Tycho Brahe, who worked together at […]
