I guess it was inevitable that in my wider reading on subjects such as astronomy and physics I would eventually bump into quantum mechanics. Where I have encountered it so far, I have admitted it went straight over my head. It might thus seem foolhardy for a biologist to try and tackle a book like this. Then again, the hallmark of good communicators is that they make complex topics understandable. And theoretical physicist Sean Carroll’s previous books have been lauded, some even winning prizes. Are you ready to get down and dirty with quantum mechanics?
