You might think that this book has received four stars, but if you know anything about quantum theory you will be aware that a quantum object can be in a superposition of states. And this quantum book is in a superposed state of 5 stars for the subject - which is fascinating and important - and 3 stars for the writing - which is disappointingly poor, given Jim Al-Khalili's expertise and experience. It might seem that the whole concept of 'quantum biology' is a truism that hardly needs exploring. When every chemical reaction or electrical activity in a living organism is based on the interaction of quantum particles, why would there be a need for a separate discipline? But the (still relatively few) workers in the field like quantum physicist Jim Al-Khalili and biologist Johnjoe McFadden are looking at special cases. Where quantum effects, like entanglement, have a direct impact on large scale systems. Whether it's the robin's ability to steer using a molecular mag...
