I was just after watching it, I guess you're subscribed to sixtysymbols too

All the science videos from the University of Nottingham's youtube channels are superb. I've watched nearly all of the sixtysymbols/ periodicvideos/ numberphile/ deepsky videos.

I am indeed! The videos are really great. I respect them a lot for making the subjects interesting through the way they present them. Other university videos are informative and sometimes interesting, but they lack the enthusiasm and effort that Nottingham Uni put into theirs.

Although not birefringence, I have always appreciated the explanations I have heard in explaining the below observation

Although not directly related to either birefringence, or that weird symmetry in the word dioxide.

Something I've been looking at

I've been looking at it, because I am dyslexic. Though as an adult, I have mostly overcome it, I still have problems. I have a pet theory, that if I learn to, and practice, reading upside down, and back to front, it may improve my general reading and maths. It's interesting to do. You get a reminder of how difficult it was to learn to read as a child - for me it was especially difficult.

Birefringence was always my favourite physical property
