H tends to zero

Engrade

Engrade is a free online grade book service where you can record and securely share grades and assignments.

I am going to try the service out with a couple of classes this term. I am interested to see whether the pupils and parents would use it and find it useful.

I don’t intend to use the built in grading system, e.g. 80-100% = A, etc. You can modify the grading options to suit and I aim to use our department’s traffic light system.

Hopefully I will be able to post an update at the end of the term.

The Story of 1

Mr H — Sun, 14 Aug 2011 14:20:22 +0000

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.
