The Edison and Marconi situations. Marconi in particular. Tesla invented the radio, and published diagrams for it in a magazine. Marconi took those diagrams, built a radio using Tesla's patents, and pawned it off as his own, claiming to be the inventor of the radio, to which is is widely given credit for to this day. Even though the Supreme Court ruled that the patents properly belonged to Tesla as the inventor of the radio, and smacked down Marconi, Marconi is still taught in schools as the "inventor" of the radio, with scant mention of Tesla. Without Tesla, we wouldn't have any type of modern electronics. Every piece of electronics uses high frequency coils which make them possible. Without his work pioneering the use of radio frequency, we wouldn't have any type of wireless communications. We wouldn't have florecsent lights either. He developed so many things, and had such revolutionary concepts for his time, that he scared the living sh*t out of most people. Yet, with his massive contributions to science and technology, he's hardly mentioned in science textbooks. He's barely given any credit in school science classes. I've always been a big fan of his work, and am impressed with how frighteningly revolutionary his ideas were. As a matter of fact, I recently read a news article about how some computer companies are developing wireless chargers and power systems for small devices like laptops, iPods and cell phones. They talked about it like it was new. This was technology Tesla pioneered and patented 100 years ago! Yet, no mention of him in the article. That's it in a nutshell.
