I love this explanation of entropy

I have always been confused about exactly what it means. I didn't understand what was the relationship between heat and disorder. I didn't get why this concept was explained in every Thermodynamics textbook so badly but now I get it. I'm a fucking mechanical engineer and I never understood this till now because of this video.

I feel ashamed I never understood it now because that relationship I realize now is so profound.
