|
| ==Personal Life==
| |
|
| |
| Qian Xuesen was born in Hangzhou, the capital of Zhejiang province. He left Hangzhou at the age of three, when his father obtained a post in the Ministry of Education in Beijing. Qian graduated from jiaotongUniversity in Shanghai in 1934 and received a degree in mechanical engineering, with an emphasis on railroad administration; he then spent an internship at Nanchang Air Force Base. In August 1935 Qian left China on a Boxer Rebellion Indemnity Scholarship to study mechanical engineering at the Massachusetts Institute of Technology and earned a Master of Science degree from MIT a year later.

| ==Career in the United States==
| |
|
| |
| In 1943, Qian and two others in the Caltech rocketry group drafted the first document to use the name Jet Propulsion Laboratory; it was a proposal to the Army for developing missiles in response to Germany‘s V-2 rocket. This led to the Private A, which flew in 1944, and later the Corporal, the WAC Corporal, and other designs.

|
| |
| ===Theory of Relativity===
| |
|
| |
| Einstein's Theory of Relativity (sometimes known as the Theory of Special Relativity or Theory of General Relativity) determined that time and space are connected on a plane referred to as space-time. Massive objects create distortions in the space-time plane. Much as a heavy object on a piece of paper pulls the paper down, the impact of these massive objects on the space-time plane is what we feel as gravity.

| ===Worm Holes===
| |
|
| |
| Wormholes (often referred to as the Einstein-Rosen Bridge) are hypothetical passages between far off points across the universe. Though the Theory of Relativity predicts the existence of wormholes, one has yet to be discovered. The wormhole concept of a shortcut across the universe has engaged prospects of teleportation, though there are a number of issue ranging from size to stability that prevent the survival of anything travelling through a wormhole.

| ===Fun Facts===
| |
|
| |
| Einstein was offered the position of President of Israel, but refused stating his lack of "natural aptitude and the experience to deal properly with people"
| |
|
| |
| Einstein enjoyed sailing, playing violin, and smoking pipes.
| |
|
| |
| "Albert Einstein is an anagram of 'Ten elite brains'"

|
| |
| ===Myths Debunked===
| |
|
| |
| Despite popular belief, Albert Einstein did not work on the Manhattan Project. The US Army refused to provide him the necessary security clearance, likely due to his liberal political ideology. Nevertheless, Einstein had written President Franklin D. Roosevelt a letter outlining the development of a fission uranium bomb, a decision he is said to have later regretted. Einstein's letter helped spur the development of nuclear weaponry.
| |
|
| |
| The rumor that Einstein failed at mathematics in primary school is incorrect. By twelve, Einstein had already begun studying calculus and developing his own mathematical proofs!
