What biochemistry and cellular biology tell us

We have seen how the universe grew from a tiny point to become the enormous – probably infinite – place we see about us. We have focused on a small part of this huge entity and have seen how our solar system has formed and then our planet; how the Earth evolved to reach its current – but temporary – state of support of life; when life was born and how it evolved from bacteria to plants and marine creatures, then land creatures like dinosaurs, then mammals and primates and – currently – us.

So now what? Well, there’s us. But a complete study of that subject is well beyond the domain of this document, so let’s concentrate on a limited subset of it. As a former physicist and informaticien, and so naturally interested in energy and communications, I will emphasize those two threads in studying the human body. That, at least, is the goal. This route should lead to the ultimate and most subjective-seeming domain, cognitive science – the study of the brain.

We must start small, though, with cells, as all else follows from them. And in order to understand them, we need to know
