Working with my Further Mathematics students on a work / energy question based on the Jack and Jill nursery rhyme started a lively discussion on what other stories and rhymes we could turn into Mechanics questions! We all immediately thought of Humpty Dumpty! I think the examiner was having fun with this one – the question carries on with poor Jack falling over and hurting himself. Jill seems to get off lightly unlike the original! If anyone is interested this is question 4 on the June 2007 MEI M2 paper.

Staying with the subject of Complex Numbers, with the same students, another discussion we had recently when looking at Complex Numbers was the need to write clearly, a z can look like a 2 for example. See Mathematical Handwriting on Mathematics for Students. Also on Mathematics for Students I have updated the page giving links to A Level Exam papersto include some really useful solutions resources such as David Smith’s worked solutions.

The inability of American kids to write a two-half-circles x has led to the introduction of the fat circle as a multiplication sign. Sad, in’t it.
