I have done it! I have finally finished reading "The
Road to reality" by Roger Penrose. I probably started reading
the book about 5 years ago, but I thought I should finish it
before I move in August.
I now know that Roger really really likes complex numbers. It was interesting to read the work of someone who thinks geometrically.
Ok, so now I know Physics. Don't bother to ask me any questions about fibre bundles or twistors. I didn't do a very deep read.
