i In the frame: Eileen Cooper accuses the art world of failing women

Paul Erdos was one of the most brilliant and probably the most remarkable of mathematicians of this century. He greatly influenced many branches of mathematics and was the prime mover in the rapid growth of combinatorics, an area of mathematics fundamental to computer science.

A-Z of the digital world

Z is for Zeroth. With a neat circularity that should please the true hacker - the last item in our catalogue means "first". For software designers working in C and the artificial intelligence language Lisp, the first item in a list is always the "zeroth" (zee-rowth). Hardware people also tend to start counting at 0 instead of 1 - a natural result of the fact that the 256 states of 8 bits correspond to the binary numbers 0, 1, ..., 255 and the digital devices known as "counters" count in this way.

THEATRE / The Fringe: Rising from the ashes

There's so much new writing on the fringe that you might be forgiven for thinking a new play festival was gilding the lily. But one great advantage of the London New Play Festival is that it gives the work a clear context and allows audiences to compare how very differently young writers are using the stage. So far, this year's festival has done this ingeniously, launching plays in pairs that have themes in common, but whose styles contrast enormously.
