A few weeks ago I had the privilege to attend a talk by Simon Singh at the Adler Planetarium. It was a engaging and entertaining talk. If you have the opportunity to see one of his presentations, I recommend it.
At the close of the presentation I found out that Dr. Singh was signing copies of his new book Big Bang: The Origin Of The Universe. I figured what the heck and I picked up a copy. If you have the slightest interest in the history of astronomy and cosmology then I high recommend this book. Dr. Singh has a great writing style and the book is a quick read.
