NPR's Robert Krulwich on Intuitive Mathematics
creativelearningmsu: Last month, when Vi Hart’s math doodling video (below) was zooming around the internet, Robert Krulwich (NPR science correspondent and host of the fabulous Radiolab) made a wonderful connection. You may have noticed she’s a touch angry about how math is taught in America. She thinks it can be done better — more intuitively, joyously. So does Paul Lockhart, a math...
The awkward moment when your Algebra II teacher -
shahnaynay: is doing an unfathomable equation on the board, finishes, then walks away with more swagger than T-Pain. He’s all, “Get at me, brah.” And we’re like;

rmward: The complex math our brains are capable of is amazing, and the fact that it’s approximate and completely non-numerical makes it all the more fascinating to me. I’d love to understand how our brains can instinctively figure out the flight path of a thrown ball, but (most of us) can’t do relatively simple multiplication in our heads.
Sheldon: What is the best number? By the way, there's only one correct answer.
Sheldon: Wrong! The best number is 73. [Short silence] You're probably wondering why.
Leonard & Howard: No no, we're good.
Sheldon: 73, is the 21st prime number, it's mirror 37 is the 12th and it's mirror 21 is the product of multiplying, hang on to your hats, 7 and 3. Did I lie?
Leonard: We did it! 73 is the... Chuck Norris of numbers!
Sheldon: Chuck Norris wishes! In binary, 73 is a palindrome, 1001001, which backwards is 1001001, exactly the same. All Chuck Norris gets you backwards is Sirron Kcuhc!
Raj: Just for the record, when you enter 5,318,008 in a calculator, upside down it spells BOOBIES!

«Let’s imagine I’m throwing a party, a welcome reception for future time travellers. But there’s a twist. I’m not letting anyone know about it until after the party has happened. I’ve drawn up an invitation giving the exact coordinates in time and space. I am hoping copies of it, in one form or another, will be around for many thousands of years. Maybe one day someone living in the future will...

Wikipedia | Banach-Tarski paradox →
The Banach–Tarski paradox is a theorem in set theoretic geometry which states that a solid ball in 3-dimensional space can be split into a finite number of non-overlapping pieces, which can then be put back together in a different way to yield two identical copies of the original ball.
When my teacher hands back our Math exam:
itsforeverornever: At first I know I failed so I accept the fact that I’m a failure at life: Then I get it back and it’s not as bad as I thought it would be: Then I hear the bitch behind me crying because she got 95%: She makes me feel so sad about my mark so I just glare at her: But then I remember I’m better looking than her so I’m like: But really I turn around to her and I’m...
2011 in phi
fuckyeahfibonacci: The first occurrence of the digit sequence ‘2011’ occurs in the decimal expansion of phi (the Golden Ratio) at decimal place 7495. Interestingly, it is preceded by an additional 3 repetitions of the digit ‘2’ and followed by the sequence ‘62’ repeated twice. ‘2011’ does not reoccur in phi until decimal place 15192.
