The convenience of electrical power is all around us. Like many things it is so much the background to our lives that we take it utterly for granted. Yet, in this case as in so many others, we are standing on the shoulders of giants. One giant to whom we should be grateful is Michael Faraday […]
The intuition that ‘all is one’ dates back at least to the early Greeks. This sense that there is a fundamental unity to all existence is expressed in Parmenides(https://en.wikipedia.org/wiki/Parmenides), and is found in much of the ancient religious tradition of the Far East.

As I write on 19 December 2015 people across the world are preparing to put an organ in their bodies through an assault course. This annual ritual is known as ‘Christmas’. The organ in question is not much discussed in polite conversation, and preferably not at a sacred time of the year. It is the

The terms ‘gene’, ‘genetics’, ‘genetic engineering’, ‘gene therapy’, ‘GM crops’ etc. have been current in the media and everyday conversation for a good while now. They are bandied around more than the science behind them is understood. Fortunately, there is a good crop of books for the general reader to gain some understanding. Examples are Matt
Have you ever been baffled or intimidated by what physicists tell us about the fundamental structures of the universe? Well, snap. Without a very sophisticated understanding of mathematics most of it is over our heads. Some leading physicists have tried to offer books for the general reader. One was Richard Feynman with his celebrated best-seller Six

All human cultures that we know of, literate and non-literate, have constructed stories about their own origins. It’s a perfectly natural thing to do. At an individual level the child asks ‘Where did I come from, Mummy?’ So, it’s equally compelling for a tribe or civilisation to ask ‘Where did we come from? The answers,

Ever wonder what happens to your mortal remains after your spirit has taken the celestial elevator? Journalist and author Mary Roach (http://www.maryroach.net/) offers us this informative and humorous study of the human corpse. Human beings continue to die with alarming frequency: about 6,350 every hour at the last estimate (http://www.ecology.com/birth-death-rates/). That’s an awful lot of solid
