Review: Life on the Edge: The Coming of Age of Quantum Biology
Johnjoe Mc Fadden and Jim Al-Khalili
Quantum biology? I had never seen those two words together before, so I had to read this book. And now I have and liked many parts of it. The authors try to explain quantum biology to the lay person, like me, and after reading this I understand at least some of it. Repeated warnings appear throughout the text that the subject is not really as simple as some of their examples, so there’s much more out there than they included in this book. Early portions of the book include a history of the development of quantum theory and many notable people related to that.
How do robins know where to go when it’s time to migrate? What does that have to do with quantum mechanics? And what has any of that to do with biology? It’s quite a task for the reader to keep up with all the dots that must be connected to draw the lines through the robin, quantum mechanics and biology. One that only the hardy will finish.
This is not an easy read. And in my opinion the first half of the book does not make the task any easier. It is uneven in its presentation, seemingly not able to maintain the level for the uninitiated reader. The back half makes their case most clearly that quantum stuff can happen in the world of biology. How the belief otherwise came to be is odd since quantum has to do with atomic, molecular stuff, but the biologic world was formerly off limits because of its squishy, warm environment which makes research much more complicated. As methods and tools improved in biology, chemistry, and physics, to say nothing of biology and physics actually communicating with each other, some began to look deeper and that is what this book is really about.
The ideas are challenging, and the applications fuel the stuff of science fiction. The attempt to define concepts like consciousness and life in a manner that makes them accessible to the science community is still up in the air. The authors seem to subscribe to a quote from Richard Feynman, “Everything that living things do can be understood in terms of the jiggling and wiggling of atoms…” (59) while they agree that livings things differ significantly from the inanimate. They practice the quantum idea of being in two places and states of being at once as they try to balance this presentation to the lay person.
I would recommend this book primarily to those that have done some reading about quantum ideas first and to those that are willing to stretch to grasp the idea of a living office building (315).
I received this book from the publisher in return for a review.
