Vi Hart explains why some infinities are larger than others

If you need something to wake up your brain this morning, listen to the soothing sounds of Vi Hart talking about mathematical infinities.

Mathematical beauty activates the same portion of the brain as great art

Even though math and art are sometimes seen as being opposites, both activate the same part of the brain that appreciates beauty. So whether it’s the Mona Lisa or seeing someone compute the movement of subatomic particles, they both are interpreted by your brain as “damn that’s pretty”. And it is.

IHC After Dark short films: “Niels”

IHCer’s first short film looks mathematical…

"Brian’s brother is locked in a box comprised of mathematics. Brian is trying to find the key to get him out."

Morning mindfuckery: Why the sum of all positive integers is -1/12

It doesn’t make any god damn, but it’s a rock solid fact of mathematics— that if you add up every single positive integer out there, which is a lot, the sum will be -1/12. Why is that? If I could even begin to explain it on my own, I would’t be so bad at not being broke.

How To Always Win In Connect Four

In a nutshell: always go first, always drop it down the middle on your first move, and as long as you don’t play like an idiot the game’s all yours. Math.

And now, here’s a simple math puzzle that will melt your brain

1+1-1+1… etc sounds simple, but this video will show you there are actually three different answers.

Is math a feature of the universe or is it just something humans made up?

Mind blown.

Need your brain scrambled? Here’s a list of logical and mathematical paradoxes

I’m not exactly sure how I ended up on the Wikipedia page listing dozens of paradoxes of infinity, but I did. And I read the whole damn thing and it kind of hurt my brain a little, so I thought I’d share.

Know your awesome engineers of history: Charles Proteus Steinmetz
The great mathematician and engineer Charles Proteus Steinmetz, a contemporary of Albert Einstein, Nikola Tesla and Thomas Edison stood only four feet tall and was crippled and bent by kyphosis but was a giant in his field. One day, when Henry Ford’s, electrical engineers couldn’t solve a problems they were having with a gigant generator,Ford called Steinmetz. Upon arriving, Steinmetz rejected all assistance and asked only for a notebook, pencil and cot. Steinmetz listened to the generator and scribbled computations on the notepad for two straight days and nights. On the second night, he asked for a ladder, climbed up the generator and made a chalk mark on its side. Then he told Ford’s skeptical engineers to remove a plate at the mark and replace sixteen windings from the field coil. They did, and the generator performed to perfection.Henry Ford was thrilled until he got an invoice in the amount of $10,000. Ford acknowledged Steinmetz’s success but balked at the figure. He asked for an itemized bill.
Steinmetz responded personally to Ford’s request with the following:Making chalk mark on generator $1.
Knowing where to make mark $9,999.
Ford paid the bill.

It took one Japanese guy seven years to draw this “unsolvable” maze

Twitter user Kya7y recently posted a picture of a hand-drawn maze her dad made that took him seven years to complete. The maze has sparked interest from both the art world and the math world, because just look at it… it’s gorgeous and intriguing. Kya7y says her father claims the maze is unsolvable, but someone’s going to rig up some clever piece of technology that will solve it. Or not. Maybe a thousand years from now.

How tall can you build a Lego tower before it crushes itself?

In the last few years, there have been some pretty tall Lego towers built, each one claiming the title of “world’s tallest”. How tall could you build a Lego tower before it’s crushed under it’s own weight? Pretty damn tall, actually. If you’re talking 2x2 bricks, you could get a tower over two miles high before the bottom Lego is destroyed.
