    Syllabus development

    You seem to be saying that teachers should just accept a substandard syllabus and if good students want to learn pure maths they should give up on Australia and go to the US or Europe. Some schools won't accept this. We already have several schools teaching the IB for example. As for uni's...

    Syllabus development

    It's a case of the uni's, governments and the BOS having to get used to being publicly exposed for the amateurs that they are - and a case of teachers ignoring them and doing it properly instead. Many schools advertise themselves as striving for excellence. Can they do this with a substandard...

    Syllabus development

    It has previously been suggested to the BOS that they bring back the 2-year Level 1 course, and that they should include Number Theory if they did that. It seems they won't be doing that. Instead their writing brief seems to be obsessed with the utility of maths and pays scant regard to the...

    Syllabus development

    If you ask mathematicians what they do, you always get the same answer; they think. They are trying to solve difficult and novel problems. They never think about ordinary problems. - M. Evgrafov, Literaturnaya Gazeta, no. 49 (1979) 12. So the BOS should not only keep Harder 3 Unit and...

    Cubics and quartics

    Here's an alternative way to do last year's 4 unit question on cubics. I bet you thought the answer was x<sup>3</sup>-20x+24. But that's too boring. Of course, a better question would be that if two distinct points on E: y<sup>2</sup>=x<sup>3</sup>-5x+3 are A(x<sub>1</sub>, y<sub>1</sub>)...

    Molecular Möbius Strip

    Analogous to cutting a paper Möbius strip is to break the double bonds with ozone. This picture is from a 1982 article in C&EN: http://4unitmaths.com/cen1982.pdf Note however that this must be done under carefully controlled conditions. First it has to be dissolved in dichloromethane and...

    Are you referring to e=&sum;1/n!? I agree that this can be done with Taylors series. However, it can also be done without it - again within 2 unit. I prefer however not to dwell on this point in the 2 unit proof of the irrationality of e. I also prefer not to make excuses for mediocrity ..........

    Syllabus development

    Fighting against philistines in the teaching profession often makes maths interesting. Philistine teachers make excuses for not doing interesting maths - which goes something like this: - it's not in the syllabus or - you'll have to wait till uni to do it For example for many...
