In March of this year, the average IQ of our entire planet dropped by a couple of digits. We lost one of the cleverest and most inspirational men who ever lived. Professor Stephen Hawking, the astrophysicist who published "The Theory of Everything" had left us, and we were all a little dumber for the loss.
The fact that Hawking survived as long as he did was incredible. He was diagnosed with ALS when he was just a student at Cambridge University, and the prognosis for his life expectancy wasn't good. Defying all the odds, he made it to the age of 76. He may have been restricted to a wheelchair, but his mind was sharp as a tack, and he was known for his wit, delivering withering put-downs in his distinctive 'voice' to comedian John Oliver during an interview in 2014.
