I am a German mathematician, astronomer, and astrologer. I am a key figure in this century's scientific revolution. I am best known for my laws of planetary motion, based on my works Astronomia nova, Harmonices Mundi, and Epitome of Copernican Astronomy.
I was the first to determine that refraction drives vision in the eye, and that using two eyes enables depth perception.
So basically in simple language I discovered how planets rotate and orbit
