Get smarter: Go down the Pascal’s Triangle rabbit hole

It's been called the Staircase to Mount Meru and the Khayyam Triangle, but many people know it as Pascal's Triangle. It's an infinite triangle of numbers with ones on both risers, the positive integers at the next diagonal, and then it just goes crazy from there. There are formulas for developing a row or a diagonal. You can black out the odd numbers and make fractals. Watch the video above, read more about the triangle, and then check out the Sierpinski triangle, which is the equilateral triangle fractal you can make from Pascal's triangle.

Careful, you might need a nap afterward to process all of it.
