And maybe, well, I mean, if you go into almost any scientific field, you might even argue it's the single most important concept. And I've actually told people that it's kind of sad that they don't cover this in the core curriculum. Everyone should know about this, because it touches on every single aspect of our lives. And that's the normal distribution, or the Gaussian distribution, or the bell curve. And just to kind of give you a preview of what it is, and my preview will actually make it seem pretty strange, but as we go through this video, hopefully you'll get a little bit more intuition of what it's all about. But the Gaussian distribution, or the normal distribution, they're just two words for the same thing. It was actually Gauss who came up with it.
