h2g2 The Hitchhiker's Guide to the Galaxy: Earth Edition

The Open University have a Maths programme about this.
"Hotel Hilbert
Exploring the strange mathematical world of infinity at a hotel which is always full but still takes in guests."

Made in 1996 but still being shown (I watched it again this weekend). It's very unusual for an OU programme, being more of a comic drama, with Suzanna Doyle (Drop the Dead Donkey) and Patrick Barlow (theatre of Brent).

Its worse than that Jim, the very programme was on rather late forcing me to watch it and stay awake contemplating infinity. The end result was I decided infinity was a circular bucket and thus satisfied dozed off to sleep. A day later.

It's on again, in the early hours of course. 4am to 4.30 Sunday 16th October 2005, which could be called late Saturday night if you were staying awake.

It's a bit of a tradition in my house to tape it and watch it every time it's on and then spend our time discussing infinity. I will try and remember the circular bucket.
