It seems to me that the world is set up in such a way as to give men an unfair advantage. (Lucky me.) And not just because they are men — more because the world is set up so that certain kinds of behaviour are favoured, and those behaviours are more common in men than in women. There are behaviours that are thought of as typically masculine or feminine, but talking about them in those terms just reinforces the stereotypes that we should try to abolish. As soon as we say “men are like this”, someone else will reasonably say “not all men!” and we end up with an argument instead of progress.Continue reading

One of the great joys of mathematics is the incontrovertible feeling that you’ve understood something the right way, all the way down to the bottom.
This amazing book sets out a mathematical framework for describing and constructing numbers, and then generalises this to a way of analysing certain games. You probably need a postgraduate degree in mathematics to really understand all of it. I am not quite that qualified, but I know enough to be awed by what can be done by simply starting with nothing. Literally nothing: Conway starts with just an empty set, and proceeds to show how to spin this out into integers, rational numbers, real numbers, infinite numbers, infinitesimal numbers, and (believe it or not) more.
The whole class of numbers he constructs is called the Surreal numbers, and that’s a fair evocation of the way this book stretches my mind. I can generally understand the steps in the various derivations, but it takes some time and effort to develop the intuition to really understand the later constructions and to see where they are heading. Conway obviously had this intuition: after working on the ideas for some years, he wrote this book in just a week.
