The Oatmeal:

Over one hundred years ago, a Serbian-American inventor by the name of Nikola Tesla started fixing things that weren’t broken.

In a time when the majority of the world was still lit by candle power, an electrical system known as alternating current was invented and to this day is what powers every home on the planet.

Unquestionably the best thing posted on the internet today. There hasn’t been a person born who has had more impact on modern daily life than Nikola Tesla.
