It's somewhat unthinking of me to suggest you spend nearly 10 minutes watching this video about Nikola Tesla, but I offer it anyway. Tesla, as some of you know, lived in the first half of the 20th century and was a remarkable inventor whose revolutionary ideas have ushered in what some call the "Second Industrial Revolution."
His breakthroughs in electricity, magnetism and wireless technology were of world-changing magnitude. His ideas were so advanced and so revolutionary that powerful men stomped him into penniless obscurity. This video does a fair job of capturing Tesla's story, especially his undoing at the hands of Edison, the financier J.P. Morgan and even J. Edgar Hoover.
From his early years in Serbia, Tesla said his motivation was to make the world a better place for all people, and he dedicated his life to that goal. Here's a synopsis of genius and how it can be destroyed when it threatens the status quo.
