The Story of 1

Terry Jones (of Monty Python’s Flying Circus) goes on a humor-filled journey to recount the amazing tale behind the world’s simplest number. Using computer graphics, “One” is brought to life, in all his various guises. One’s story reveals how celebrated civilizations in history were achieved, where our modern numbers came from and how the invention of zero changed the world forever; and saved us from having to use Roman numerals today.

The Klein Bottle

The Klein Bottle is a surface on which you can move from outside to inside without crossing an edge. This shows that inside and outside are not universal concepts.In this movie Klein’s Bottle is constructed by gluing an rectangle along the edges. Then the bottle is cut up again to yield a Moebius-strip.This video was produced for a topology seminar at the Leibniz Universitaet Hannover.

What’s this all about?

I have a rather large list of ‘websites to check‘ in my favourites, lots of ideas gleaned from tweets, a pile of pages to ‘read later’ in my Readitlater account, even more in my Bloglines account and I really need to start organising them into one place I can easily access and share.  Hence this blog!

So far I have just imported some videos from a blog I use with my pupils and also uploaded most of the resources I used to share via my mathsroom.co.uk website.

Why ‘H tends 2 Zero‘?  My nickname is ‘H’ and it’s a maths phrase.

Well, here goes….

I love Maths!
