What does a 24-hour clock look like? In our history reading, we were studying how time has been segmented and thought of for the past few thousand years. It was fascinating. I mean, a day is a day is a day, but someone randomly chose that time to be divided into 24 hours, which is made up of 60 minutes, which are made up of 60 seconds. And now our entire planet (okay, not the remote villagers) uses this system and liiiiivvvvves by it. Wow!
How is pi calculated? We've been on a bit of a "pi" kick ever since 3-14 of this year. Who knows why. So we've watched videos about pi, songs about pi (tau), used big ol' numbers and my scientific calculator to calculate pi... you get the idea. I was a math major (yes, I was) (seriously, I was) for two full semesters and *I* never learned the meaning of pi. So once again, my kids are making me smarter (which is not hard to do).
