Randall forgot psychology, which has involved a ton of putting animals in boxes...
What about goats in circular pens? A goat is tied to the fence of a circular pen. How long does the rope need to be so that the goat can reach exactly half of the pen's area? What sounds like a high school math problem was eventually solved in 2020 via complex analysis.
Here's the answer:
I guess a key thought experiment doesn’t qualify as a reason, and also we are supposed to conveniently forget about putting spherical cows in a vacuum just because.
We have one for combinatorics: Ask Fibonacci about his rabbits.
I'm still trying to fill that hotel with infinite monkeys
I'd expect something around ~200 for n=9 and ~400 for n=10, but I imagine this is too big to be brute forced by raw computing
My combinatorics professor used gnomes!
In biology it’s less of a “thought” experiment
Either I'm misunderstanding the problem or a length of 8 is possible.
Edit: found my mistake, far left edge has two non-consecutive segments on adjacent corners. Leaving this up in case anyone else tries for a better score.
