Sheffield Festival of Science and Engineering

This year we decided a full weekend of Sheffield Festival of Science and Engineering.  The Sheffield Hallam's Science day is much better than Discovery night, for a start, it was less claustrophobic, and biscuits always help, lastly, I saw a very unusual demo, checksums!  Ultimately, it is meant to dazzle kids and get them interested in science, but takes a lot more to move me.

Then on Sunday, we sat in a few talks, which was quite good demo, a few new tricks.  I am quite Sheffielded out.
