oh... super... super super super :) thanks .... "things are going to get exciting.." oh boy ..they are exciting from the beginning ;) because i knew something about that subject but i did not understand it .. but right from the begining of your videos i started to connect things and began to understand! eventually! so ... thanks :)
Is it possible to have a crystal system where the lengths of a b and c are not equal, but only one angle is 90°? This wouldnt be monoclinic, so would it be triclinic?
For any geology or mineralogy students watching, there are lots and lots of triclinic and monoclinic crystals in real life, including some of the most common minerals in the Earth's crust. (eg. monoclinic = clinopyroxene, phlogopite, sanidine, orthoclase, and many more; triclinic = microcline, albite, anorthite, turquoise, and many more). These videos are great otherwise!
When describing orthorhombic crystals you forgot to put a does not equal sign between b and c, I got a little confused because I didn't hear you say not equal at first. Maybe you should point it out with an annotation?

Also you missed a few modulus signs, that's fairly minor though.
