## Tycho Brahe and Johannes Kepler

He convinced himself that, given the uncertainties of observation at the time, this picture might be the right one. However, that was before Tycho's results were used.

Kepler realized that Tycho's work could settle the question one way or the other, so he went to work with Tycho in Tycho died the next year, Kepler stole the data, and worked with it for nine years. He reluctantly concluded that his geometric scheme was wrong.

In its place, he found his three laws of planetary motion: I The planets move in elliptical orbits with the sun at a focus. II In their orbits around the sun, the planets sweep out equal areas in equal times. III The squares of the times to complete one orbit are proportional to the cubes of the average distances from the sun.

These are the laws that Newton was able to use to establish universal gravitation. Kepler was the first to state clearly that the way to understand the motion of the planets was in terms of some kind of force from the sun. However, in contrast to Galileo, Kepler thought that a continuous force was necessary to maintain motion, so he visualized the force from the sun like a rotating spoke pushing the planet around its orbit.

On the other hand, Kepler did get right that the tides were caused by the Moon's gravity.

Galileo mocked him for this suggestion. InBrahe invited Kepler to come work with him. Brahe, however, soon became suspicious and unwilling to share his notes with his assistant.

Instead, he assigned Kepler to solve the mystery of Mars, one of the most puzzling problems in astronomy at the time. Ironically, the detailed records of the planet were the tools Kepler needed to understand how the solar system functioned. The Martian problem, which Kepler said he would solve in eight days, took nearly eight years. Astronomers had long struggled to figure out why Mars appeared periodically to walk backward across the night sky.

Some planets, such as Earth, had an orbit that was very close to a circle, but the orbit of Mars was one of the most eccentric, or widely stretched. Mars appeared to move backward when Earth, on an inner orbit, came from behind the red planet, then caught up and passed it.

Copernicus had suggested that observations made from a moving Earth could be a cause of the retrograde motion, but the perfect circular orbits he proposed still required epicycles to account for the paths of the planets. Kepler also struggled with changes in the velocities of the planets.

He realized that a planet moved slower when it was farther away from the sun than it did when nearby. Once he understood that planets traveled in ellipses, he determined that an invisible line connecting the sun to a planet covered an equal amount of area over the same amount of time.

He posited this, his Second Law, along with his first, which he published in Specifically, the square of the ratio of the period of two plants is equal to the cube of the ratio of their radius. He was the first to determine that refraction drives vision in the eye, and that using two eyes enables depth perception.
