Quantum Physics and life by Ingemar Ehrnberg and others

About

This book is written for the general public so no math or too many technical terms.

As the title suggests this book is about quantum physics and explains it through how it intersects with biology. We only perceive a fraction of the world. The spectrum of visible light is only a fraction of the electromagnetic radiation that exist. The same is true for physics, the classical physics of gravitation and movement is only parts of the forces governing the world the rest is the weird mess that is quantum physics. 

But just because it's weird doesn't mean it doesn't affect us or that evolution cant use it. Like how geckos use nano-hairs under their feet to stick to walls and ceilings. How birds can see the earths magnetic field to find their way home. Or how chlorophyll catches light. 

My thoughts

It is a short book with only 150 pages. Actually less since each chapter has three pages just for the heading and a quote. A bit ridiculous especially for chapter 2 that's only 4 pages. It brings to mind the times I had to reach a specific page count but didn't have the text for it.

I've read books and watched documentaries about quantum physics before, so for me there were parts I already knew but also a lot of new information. Still I would have liked it to be slightly more advanced or maybe just have another 50 pages and try for a deeper explanation. A lot of the quantum physics parts are a bit glossed over, on the one hand I understand the decision these are difficult concepts that doesn't work the way anything else does. But I would like the opportunity to at least try to understand. 

But that's maybe just me in general it's a good first introduction for anyone who is interested. And relating it to familiar things is a nice addition rather than just using metaphors that never quite work.

If you have read it what did you think? Leave a comment. If you haven't read it you can check it out here quantum.
