π Day is here - 3rd month, 14th day.
I'm still loving this video:
And I'm happy Pi Day is on a Monday so I can share it with all my classes.
Here's what I found online today:
- My post from last year,
- Some 'political' arguments about changing from π to τ (tau). Vi Hart says she doesn't usually blog about politics, but makes an exception for this. I guess we're sort of opposites; I'm pretty political, but haven't gotten worked up about π versus τ,
- Some history,
- The sound of π,
- Probability and π,
- Finding π without a circle,
- A formula for the binary digits of π and an older formula,
- A trick and some puzzles,
- And of course more songs.
