Hans Einstein He finished high school at Eerde, a boarding school in the Netherlands at age 16 and moved to the United States as an exchange student. He attended Furman University in Greenville, South Carolina. One of the first things he did upon arriving was look up his last name in the phone book. The only Einstein he found was a relative: Albert Einstein's son, Hans Albert Einstein. They became friends and he was often invited over whenever Albert visited. He earned his medical degree from New York Medical College in 1946 and did his internship at Paterson General Hospital in Paterson,
Albert Einstein may be derived from the Einstein equations. Since the equations of general relativity are non-linear, a lump of energy made out of pure gravitational fields, like a black hole, would move on a trajectory which is determined by the Einstein equations themselves, not by a new law. So Einstein proposed that the path of a singular solution, like a black hole, would be determined to be a geodesic from general relativity itself. This was established by Einstein, Infeld, and Hoffmann for pointlike objects without angular momentum, and by Roy Kerr for spinning objects. In a 1905 paper, Einstein postulated that
