When you learn to count … 1, 2, 3, 4, 5, … you are increasing your number by one every time. Many number sequences are nothing more than always repeating the same algorithm. When a creature produces its shell, it is repeating the same simple building instructions as it grows, thereby creating a spiral (or one shell of a bivalve).
On a semi-humorous, semi-serious note, the idea of a day that kept repeating itself formed the basis for the entertaining movie, Groundhog Day.
In this part of the website I want to help you explore such repeating things.

Wow, how useful. … I always had a hard time with the chain rule, until I watched this video. The right presentation makes all the difference. Thank you very much. … These 20 second math videos you’ve graciously posted are excellent. I’m my little corner of the world, you’ve done great things.
