When the moon hits your eye with a big piece of \( \pi \)…

We do these things, not because they are difficult, but because they are ridiculous– Matt Parker, probably Matt Parker is going to the moon. I mean, not literally. Everyone’s favourite Stand-Up Mathematician is the sort of person who’s more likely to go to hyperspace than to space. However, when Matt was approached to do “something…
