answer:Infinity in general is pretty grand. Sometimes, if you take a graph with an infinite area under the curve, revolve that curve around the x axis to get a three dimensional shape, and then calculate the volume of that shape, oddly enough you might get a finite volume. Dimensionality is WEIRD. Also, just the thought that some infinities are bigger than others. For instance, there’s an infinite number of even numbers, but there’s a larger infinite number of integers. Also a fan of Euler’s Identity though. I left my calculus lecture feeling all tingly the day we learned that one.
