Liquid crystal physics, uniaxial nematics, do director and optical axis point in the same direction?
question relates to the physics of liquid crystals(tried to add liquid-crystal or soft matter physics tag but couldn't find one). Uniaxial nematics are a type of LC. It's easy and convenient to ...
At the seminar where the talk was about quasicrystals, I mentioned that some results on their properties remind the fractals. The person who gave the talk was not too fluent in a rigor mathematics ...
