Nick is one of those original thinkers who makes you say: More people should know about this guy’s work. He is trying to right a scientific wrong by getting people to fully appreciate the role that energy plays in all living things. He argues that we can only understand how life began, and how living things got so complex, by understanding how energy works. It’s not just theoretical; mitochondria (the power plants in our cells) could play a role in fighting cancer and malnutrition. Even if the details of Nick’s work turn out to be wrong, I suspect his focus on energy will be seen as an important contribution to our understanding of where we come from.
