July 10 is the birthday of Nikola Tesla, who would have been 161 years old today.
It's a good day to celebrate the life of the Serbian-American engineer and physicist: Without Tesla, you might not be able to affordably power your home, let alone read this sentence.
Tesla filed more than 300 patents during his 86 years of life, and his inventions helped pave the way for alternating current (AC), electric motors, radios, fluorescent lights, lasers, and remote controls, among many other things.
Some of his ideas later in life, however, seem strange even now. He once described plans for a death ray, for example, and eluded to another idea for an impenetrable "wall of force" to block and destroy foreign invasions.
Here's a glimpse into the remarkable life of one of history's most important — and eccentric — geniuses.
