You know, Darwin said through natural selection things go gradually, and he was talking about pigeon's evolution or horses evolving, getting faster. But in fact if you look at evolution on a bigger scale, cosmic evolution and you look at culture evolution you see it jumps, it goes through phase changes, and that's very exciting.

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.

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.

The rule seems to be that there are no absolutes, that what is rare is prized. Thus, in times of relative affluence, thin models become dominant.

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

Modern Architecture died in St. Louis, Missouri, on July 15, 1972, at 3.32 p.m. (or thereabouts), when the infamous Pruitt Igoe scheme, or rather several of its slab blocks, were given the final coup de grace by dynamite.

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.
