I wasn't serious when I came up with this idea, but you know how these things get out of hand. All right, listen up. Each of my fingers is a digit, but instead of a ones, tens, hundreds, thousands place, which are the powers of 10, try it again with 1's, 2's, 4's, 8's, 16's. Here I'm counting 1 to 8. Now, instead of 1's and 0's, just use your fingers, 1, 2, 3. This is how you count on your hands in binary. Going to make it easy. Write the place values on my fingertips. Count the ones you see. 4 plus 2, that's 6. 16 plus 2 is 18. You can do it up, or dance it down. Put those digits on the ground. Now do it with me. 1, 2, 3, 4, 5, 6, 7, 8. Dance it 1, 2, 3, 4, 5, 6, 7, 8. Now, pi and binary look something like this, 11.001001 dot dot dot. It's not what we're doing. We're taking the decimal version, putting each digit in binary. Now let's dance us some pi. We got 3, 1, 4. I got my bro doing 3, 1, 4. Got my mama doing 3, 1, 4. Even my grandma's doing 3, 1, 4. [MUSIC PLAYING] All right, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, oh. [MUSIC PLAYING]
