Dreams of a final theory.

An understanding of nature's final laws may be within our grasp - a way of explaining forces and symmetries and articles that does not require further explanation. 'This starting point, to which all explanations can be traced, is what I mean by a final theory', says Steven Weinberg in this extraordinary book.

In it he discusses beauty, the weakness of philosophy, the best ideas in physics and the honour of accepting a world without god.
