That maths guy from the internet.

Sorry I stole someone’s sharpie! An audience member at Wednesday’s show brought it for me to sign their calculator and were too polite to say anything when I absentmindedly put it in my pocket. It’s mine now.

I don’t understand how not doing this is even an option, assuming trucks follow classical physics. Or maybe that is the problem and the sign was too small for “trucks - despite the name, please don’t quantum tunnel through the tunnel”.

Because 2025 = 45² and 45 is a triangle number, we get these lovely sums: 2025 = (1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9)² 2025 = 1³ + 2³ + 3³ + 4³ + 5³ + 6³ + 7³ + 8³ + 9³ Pleasingly the next triangle number 55 is 10 more, so get ready for a repeat of this fact in the year 3025.
