Random facts that you will never need to know: but you know now.

From a physics perspective, decelerate and accelerate are the same thing.

Acceleration is the rate of change of velocity of an object with respect to time. That includes positive and negative velocity.

Wrong, you can't have a negative velocity. Velocity is a vector. Acceleration is the rate of change, and that rate can be positive or negative. Velocity itself can only have a magnitude.

Vectors can be negative too.

edit: Unless your point is that reference points and coordinates are all arbitrary anyway?

People may choose to call it negative or positive based on direction, but in all of the many years of physics I took, we never once called a velocity negative. You can have negative direction, but velocity is the magnitude of the vector and it doesn't make sense to change its sign based on direction. Someone driving from Houston to Dallas doesn't say I drove 60 MPH there and -60 MPH back. It would be nonsense.

Speed is the magnitude of the vector. Velocity is the vector itself.

Warwick Davis plays Professor Filius Flitwick in the Harry Potter film series, as well as the goblin Griphook in The Deathly Hallows, but in The Sorcerosipher's Stone he only voices the goblin. Verne Troyer played Griphook's body. I don't know why.
Warwick Davis has portrayed nine Star Wars characters, eight of those live-action. He's one of a few actors that are given a cameo in just about every Star Wars movie, sometimes more than once in a film. Sam Witwer's another, after getting his start in the franchise by starring in The Force Unleashed (and Galen Marek/Starkiller was even modeled after him). Since then, he's also voiced every major appearance of Darth Maul and Emperor Palpatine.

Colin Creevey only appeared in one Harry Potter movie, Chamber of Secrets, and his younger brother Dennis appeared in none. Instead, they were made into a compound character in The Goblet of Fire with Nigel Wolpert, who continued to appear in every subsequent film. He's also the youngest wizard to have fought in the battle of Hogwarts, being fourteen at the time, though in the books the youngest were Colin and Ginny (both sixteen). He actually died in the Deathly Hallows Part II's script, being carried into the Great Hall in the same fashion as Colin was, but he'd grown too much for it to look all that great, so it was never shot. Whether or not he died in the final film is unconfirmed.

Roddy McDowall played Cornelius, Caesar, and Galen in the original screen adaptations of Planet of the Apes. Except in Beneath the Planet of the Apes--he was busy directing another film, so David Watson took the role of Cornelius.

The Double (2011) and Enemy (2011) were released a day apart from each other at TIFF. They both share the similar premise of a man meeting his exact doppelganger, and are adapted from separate novel(la)s titled The Double.

Stephen dubbed the genre of his new EP as "future nature."

Men having an attraction to traps is gay. But that's okay. Maybe we should just be comfortable with love being love and lust being lust, and not worry about the terms applied. I won't judge so long as you aren't causing harm to anyone else.

I’m sure a lot of people know this but it gets me every time. The button on an iPhone makes a clicking noise that tricks your brain into thinking the button presses in but it is just a sound effect. If you turn your phone off and press the button it won’t play the sound effect and you will notice it is absolutely solid.

Funny thing - I feel the button (actually it's also a vibration) but my wife doesn't.

If bees were to go extinct, so would humans.

Or at the very least, we would be incredibly fucked but maybe just scrap through.

Cleopatra is believed to have potentially had the world's first vibrator when historians found a hollowed out "phallic" gourd that was filled with the corpses of dead bees...

Buzz buzz

That’s dirty and now I’m going to spend half a day reading if it’s true or not. (hopefully with videos)

one of history's greatest minds, Isaac Newton, stuck a needle between his eye and eye socket, pushing it as far as it could go to see what would happen (nothing too drastic).

Unless anyone knows otherwise, the word you can use the most in a row (even with periods) is "had". 11 times to be exact. Imagine a scenario where two boys are writing an essay and are unsure on whether you should use "had" or "had had" in a sentence.

John, where Jack had had "had", had had "had had". "had had" had had the teacher's permission.

spoil the party by correcting misconceptions.

This is always fun. The great wall of China cannot be seen from space. Red doesn't make bulls angry, bats aren't blind and lemmings don't commit mass suicide. Twinkies don't stay fresh for years and fortune cookies were invented by the Japanese. Vikings didn't have horns on their helmets and no-one in Salem was burnt at the stake.

There's so many of these but those are the ones I can remember off the top of my head.

Meryl Streep did the voice of Jessica Lovejoy from the Simpsons.
