Edison got tons of stuff named after him, including corporations and high schools. All Tesla got was a crappy rock band from Sacramento.
Though it wasn't all sour grapes for Tesla--while Edison invented some pretty common place items like light bulbs and record players, Tesla excelled in awesome invention like robots, wireless electricity and death rays. He predicted the Internet 80 years before its existence. Also, he was played by David Bowie in a movie.

"Immediately, I rule harder than any scientist ever."

One thing Edison and Tesla did have in common was batcrap lunacy. In Tesla's case, it was a pocket-sized earthquake generator. In 1898, Tesla conducted an experiment in mechanical resonance in his New York lab, which basically measures the tendency of something to absorb more energy from a vibration if said vibration matches its own natural frequency. In other words, everything has its own musical pitch that, if matched, will break the object, not unlike opera singers breaking crystal glasses with just their voices. Except in this case Tesla's crystal glasses were buildings.

Allegedly while testing his electro-mechanical oscillator (or earthquake machine), many buildings began to shake. Once the very building he stood in began to tremble, Tesla took a sledgehammer to the device, destroying it and likely saving everyone in the city.

"Crap, I've gotta break this damn thing."

It's not really clear why Tesla was developing a portable earthquake machine, other than the fact that he could use it to get virtually whatever he wanted, for the rest of his life. There is no further record of Tesla using or trying to market the device, though we presume he kept a working version of it in his home in case he ever caught Edison combing through his garbage.

Tesla wouldn't hesitate to murder you with science.

(bi tasarrof) And i know systa will just love this article
your right , but i still didnt get how the earth quake machine worked.
problems of performance appraisal is that it sucks to memorize them
