Just finished God and the New Physics by Paul Davies.
Probably many people on this forum have read this book and digested it easily. For me, it was a case of mental callisthenics! I now understand how infinity can be found in the area of any given circle!
Have now just started on The 33 Strategies of War by Robert Greene.
Having previously read his 48 Principles of Power, and The Art of Seduction (not a book about scoring with the opposite sex

) ,I'm looking forward to a good read with this.
In the first 50 pages he quotes from Shakespere, Napoleon Bonaparte, Friedrich Nietzsche, Aesop, Abraham Lincoln, Miyamoto Mushashi, and the I Ching, amongst others.
A random quote - More life may trickle out of men through thought than through a gaping wound - Thomas Hardy.
A different sort of callisthenics!
