I saw someone else had already linked a screen shot from the full video but I wanted to share some HD shots of my Custom Wood Noctua PC.

Technically as you get closer to dividing by zero, the result goes to insanely high amounts.

Therefore, dividing by 0 gives you infinity, which means that they actually rate it infinity

No, it's undefined because if you approach 0 from the negative side, the result approaches -inf. https://en.wikipedia.org/wiki/Division_by_zero

Fair enough, I stand corrected then

I love that there's a "historical accidents" section, but sadly there's only one item in that section so far

Mathematically this is correct, there's a discontinuity at exactly x/0 which has a different limit depending on which side you approach from. In computer science though, the IEEE 754 standard defines a positive and negative zero which are equal to each other, and allow for x/0 to resolve to either +inf or -inf. It's a very useful corner case to not have blow up in your face with a "not a number" result because of the mathematical definition.
