Over Our Heads explores the very big and delves into the very small in a way ordinary people can understand. James Sinclair takes us on a journey from the atom, through to the DNA from which we are formed, to the stars from which we came. This is one book you don't need a PhD in astrophysics or quantum physics to understand. If you've ever looked at the stars and had trouble thinking that they are just like our Sun, then this book is for you. It packs so much into just a few pages that will get you looking up at the night sky with new wonder and awe It's a book for all ages too. A 13 year old said about it, "Over our Heads is a very good book that is easy to understand, It gives a comprehensive insight to the galaxy yet doesn't confuse the reader. It is very useful for beginners in astronomy. I didn't now how interested I was in the galaxy until I read this book, and after I read it, it left me thirsting for more." And here's what an 89 year old said, "Astronomy is an ancient science with a huge bibliography. Most of this literature consists of books recording specific observations, data and speculation. The virtue of this book is that it describes and explains complex phenomena in simple terms and with analogies relating to our everyday experience. Facts become real, absorbable and easily understood."
