The numbers that make up π go on and on forever. And for centuries people have attempted to calculate and recite more and more digits of π. In 2016 a computer calculated 22,459,157,718,361 digits of π, the record so far. The current Guinness World Record for reciting π digits is held by Rajveer Meena who in 2015 and at the age of 21 recited 70,000 numbers in 9 hours and 27 minutes.
In reality scientific applications, even those that need a high level of precision, need no more than a few hundred digits when using π. Beyond that, knowing more digits is primarily for scientific curiosity or competition. Such competition is not limited to humans, though. The task of computing π to billions or trillions of decimal places is often given as a speed test for supercomputers.
How long can you stay interested in putting together the digits of π?
1. Using the list above, string the digits of π into a necklace (or bracelet) using the correct order.
2. Number beads or plastic number charms sold on the Internet can be used for this purpose. You can also make your own number beads by writing on wooden beads (often can be found at a dollar store) or on penne pasta. Thin, small wooden numbers can also be strung, especially if other beads are strung between each letter. You can also use color beads, designating a certain color for a certain number.
3. See how many π digit beads/pasta you are willing to string.

It struck me at some point a few years ago that parenting is a lot like running a country. There are many competing problems and interests and sometimes the best solutions aren’t the one you end up choosing to implement - because sometimes the best solutions are just not possible. Instead you end up choosing second- or third-best solutions. And guess what? Usually those solutions are still good, or at least better than their counterparts - no solution, or a bad solution.
So here are some things a few of our presidents learned during their terms of office, with a few anecdotes of how they relate to mine.
