Symmetries of Culture

I have got to read this in more depth later - fascinating!

Especially in Chapter 2 - translations and reflections. It reminds me so much of when I was first wrapping my brain around the coordinate system in programming POV-Ray (by hand, not with a modeller), back say... 10 years ago now.

I also ordered this book today: 'The Universe Around Us' by James Hopwood Jeans (1929)

- it was highly reccommended in this article and I love old science books.. just love them. I got my copy on abebooks.com, which is celebrating its 10 year anniversary!
