It's Time for Pi
Pi is the number you get when you take any circle, measure the distance around it, and divide by the distance across it. Any circle. A dinner plate, the moon, a ring you draw in the sand. Always the same number. About 3.14159, and then it keeps going forever without repeating.
That last part is the part that gets people. It never ends. It never settles into a pattern. You can compute a trillion digits and you are no closer to the “end” than when you started, because there is no end. Pi is irrational (you can’t write it as a fraction) and transcendental (it isn’t the root of any nice polynomial), which are two math-flavored ways of saying it refuses to be pinned down.
Non-Symmetrical Dice: When Fairness Gets Weird
A fair die doesn’t have to be a cube. A fair die just needs each face to have equal probability of landing face-up. But how do you build one that isn’t symmetric?
I’ve been exploring this question computationally. The project is at early stage but the results are already counterintuitive. More details coming as I work through the geometry and the simulations.
Where Creativity Lives in Mathematics
Around 2004, during college, my mom told me that mathematics was creative.
She was a watercolor artist. She understood creativity as something you could point at: the choice of color, the decision to leave white space, the moment you stop adding paint. So when she said math was creative too, I took it seriously. But I couldn’t think of a good example. Math felt mechanical to me at the time. You follow the steps, you get the answer. Where’s the creativity in that?
