"The Trouble with Physics" by Lee Smolin who is a theoretical physicist argues that physics has lost its way. Lee Smolin suggests that there are too many theories and no solid proof that these ideas of extra dimensions, multiple universes and strings actually can or do exist.

Speculations dominate the field of physics and Lee Smolin is concerned that it is suffocating the progress of science. What is needed is to move beyond the string theory and look for something new; question the theories and search out new big ideas.

While reading this book I had to have my iPhone with me and I was constantly looking terminology and theories up on the internet. My knowledge of physics did not allow me to read the book without a lot of help from Wikipedia. I was rewarded for my effort for I did learn more about the science of physics than I thought I would.

I got the general feeling from the book that Lee Smolin is bitter towards the string theory community and feels they dominate the world of physics and that this world needs to move onto new ideas. I found his attitude a bit supercilious and found it slightly agitating.
