In case you were curious about notable science events that have happened on April 11th…

Uh, Houston, we have a problem. On April 11th, 1970, NASA launched Apollo 13. The mission, which was to land on the moon, was cut short on the second day when an explosion crippled the spacecraft. Although the mission was aborted and the shuttle never landed on the moon, all three astronauts successfully returned home.

It’s all relative. On April 11th, 1905, Albert Einstein revealed his Theory of Relativity. His theory revealed many new and surprising possibilities. Einstein hypothesized that moving clocks are measured to tick more slowly than an observers “stationary” clock. This effect, known as time dilation, is a principle commonly associated with black holes, as any sci-fi or Stargate fan could tell you.

Einstein’s theory also explained the relativity of simultaneity (its a real word, I promise). This theory states that two events that appear simultaneous to a stationary observer will not appear simultaneous to a moving observer. Didn’t quite follow that? Me, either. Here’s a little video explaining it.

Steven never dreamed his first job out of college would be in public relations, and on top of that working for one of the top museums in the country. After all, he majored in History at Vassar College. Within three months of graduation, he landed a spot in the PR department and has not looked back since. He is fast becoming a communications fanatic, spending a tremendous amount of his time promoting the museum and all it has to offer.
