You are super cool. I love living in a time where I can go on youtube and have brilliant people explain things to me that I would once have had to devote my entire education to in order to hear. The internet is awesome, 2011 is awesome, this guy is awesome.

coooooool ,man Im so high!!!! i got it all!!! im a step closer to M theory dude!

Thank you! I'm going to raid your channel. I'm a music student studying transformation theory (an application of set/group theory) and I want to beef up my math background.

@lekoman You're very welcome :) This channel is one of those places, and I love that too ;)

@DaTux91 Thank you! I love the part of YouTube where the thoughtful people hang out. ;)

@lekoman The study of all solids has a lot to do with these kinds of groups. Geometrical symmetry is present in almost every crystal and even general solid. For example, the conductivity and optical diffraction properties of any material are closely related to its internal structure and symmetry. If we know that structure, we can predict these properties and take advantage of them. Semiconductivity and superfluidity are two examples of this. Piezoelectricity is another. All very interesting :)

@singingbanana I have a question, I am interested in group theory that analyzes the crystal structure (space group, etc). What are some group theories that are involved when analyzing crystal structure?
