The hottest and coldest temperatures in our universe are rarely witnessed, but in these rare spots, our understanding of physics is challenged. Weird things happen at extreme hot and absolute cold.

I'd wear that T-shirt.

1:40 Heisenberg Uncertainty Principle is often confused with Observer Principle. Both are different

Please tell me you bought that insane jacket and tie just for that one "Freaky Physics" joke.

TL;DW:
Coldest cold: Just above absolute zero (because absolute zero is technically impossible because of quantum mechanics)
Hottest hot: the Planck Temperature

For the FREEEAKY PHYSICSS lovers- 0:51, 3:08, 3:33, 5:22

You know, I finished my engineering course last week and I've been watching your videos a lot. Around 15 videos, and I've attained more enlightenment than I ever got during my entire engineering years. Good job! Hope to see more.

Too much goofing around. I'm not high enough to watch this.

Scientists- '"We can't get any colder than absolute zero."
Me - Well, apparently you've never met my ex.
