Everyone should know who Nikola Tesla is. This video is a great overview of the facts.

Here are some more facts:

• Tesla didn’t agree with Einsteins Theory of Relativity.
• When he was 81 he created a “dynamic theory of gravity” which science still grapples with today. This theory was never published.
• He designed a ray gun in 1934, but could not find the investment needed to actually build it.
• Tesla wanted to build a flying machine that would fly without propellors, wings, an engine or fule. It would be shaped like a cigar or saucer (Sound familiar?).
• The impact of the technologies invented by Tesla had he been more successful is a recurring theme in several types of science fiction.
