DVDs arrived
Today’s a public holiday in England so there’s no in-depth Monday post from me. Instead here’s a picture of me with a two boxes of DVDs on teaching students to write mathematics.

I wish you and your co-authors (if that’s the word for those making a DVD) the best of luck with this project. I sometimes wonder just how many people going through the school system get away simply with memorising things. Some people (like my late father) seem gifted with a photographic memory for text – he could roll off lines and lines of Shakespeare, John Milton et al, and also (according to himself!) passed the exam for Signals Officer in World War Two mainly by memorising all the formulae for electrical theory! Such a tempting short-cut, especially the easier things like the basic formulae for differentiation and integration, or (related) the circle/sphere formulae (circumference, X-sectional area, surface area, volume to which I think you refer in your book). I guess though that memorisation might have its uses if you then go on to ask yourself just /why/ it’s such a convenient-looking and easy-to-remember formula – that’s when the fun begins.
Apologies if your system registered a ‘duplicate comment’ attempt just now – it was taking so long I thought the message hadn’t got through so re-sent.
