We start with looking at your body in the mirror. Usually you might think 'I need to lose a few pounds.' But that's not the point. Really look. What you see in front of you is one of the most amazing things in the universe. I wanted to start from your body and use that to explore science, both the direct science of what is in there and everything that contributes to making that body you.
So we explore the brain - using optical illusions amongst a whole range of experiments, and all the unexpected science in your body, like the amazing zoo of bacteria - you have 10 times as many bacterial cells as human in there. But also we get a chance to see how the science of the universe impinges on your body. We see how light from the Andromeda galaxy 2.5 million light years away stimulates your eyes. Those photons of light have been on their way for 2.5 million years, long before humans existed. Or taking a rollercoaster ride we discover how we have many more than 5 senses, detecting things like acceleration and heat - and how our bodies experience the warps in space and time that Einstein showed were the cause of gravity. That's not just a body, it's a lab to explore the wonders of the universe.
I can't remember when I last enjoyed writing a book so much - I suppose in the end because it's hard not to be interested in your own body, but more so because of all that you discover along the way.
The book has an accompanying website which includes a range of experiments, some involving the brain, for the reader to try out. Do take a look at www.universeinsideyou.com and see what you think.
As I write this, but not for long, you can get the Kindle ebook for just 99p in the UK and $1.57 in the US.
