Astronomer Bob Berman has created a delightfully easy-to-read, easy-to-comprehend book about our most revered celestial object in his book "The Sun's Heartbeat". But don't let this book's lighthearted simplicity fool you- it is absolutely packed full of the most fascinating information I'm sure you've never heard. For example, did you know that the sun reverses it's polarity every 22 years? Or that it loses 4 Million tons of itself every second? Berman manages to take a somewhat dry subject and make it leap out of the pages at you in astonishing brilliance. This bok is an absolute must-read- two thumbs up!
