Pick up a sunflower and count the florets running into its centre, or count the spiral scales of a pine cone or a pineapple, running from its bottom up its sides to the top, and you will find an extraordinary truth: recurring numbers, ratios and proportions.

The cell is a city of production centres, each part working away like mad, and it's co-ordinated. Six trillion cells in a body - you can't help but be moved.

Beautiful people are always with us, as evolutionary psychologists and a trip to the news-stand confirm.

Science is a victim of its own reductive metaphors: 'Big Bang,' 'selfish gene' and so on. Richard Dawkins' selfish gene fitted with the Thatcherite politics of the time. It should actually be the 'altruistic gene,' but he'd never have sold as many books with a title like that.

If you look at any leaf on any tree branch, it's similar to but not exactly a repetition of the previous branch. So the new science of complexity or showing how an architecture can be produced just as quickly, cheaply and efficiently by using computer production methods to get the slight variation, the self-similarity.

You have to believe in a placebo or it wont work, but if it works, its obviously working in some indirect way, through feedback in the immune system, let us say, or in the willpower of the patient to take a more strenuous exercise in their own therapy.
