Ah Maths standards are slipping!

Just did the bbc's math quizhttp://news.bbc.co.uk/1/hi/magazine/4263590.stmI am somewhat dismayed to discover 2 of the 20 questions where incorrect, the square of a negitive number is the same as the square of the positive number a basic fact anyone should know - giving one question two correct answers. And as a physist the idea that if you roll a ball with twice the force you will have twice the velocity over a greater distance worrie me a little might be true (I can't be bothered thinking about it too deeply, need to assume a constant deceleration due to friction I guess - not really a math quaestion in anycase).I am really looking forward to my up coming escape to cornwall, holiday yay. there are lots of touristy type things I'd quite like to do but a large part of my knows I am never going to get round to them will just slob out at my parents and do a few coastal walks.On the yay front have managed to get tickets for a bath-gloster rugby match so have a day trip to bath coming up, hopefully see a few of my uni compatriots.My coding is finally going quite well (I am just trying to restrain myself from a rewrite to use some nice new techniques I've found), may even get something publishable soon (which would be long over due and fabulous). So back to it.
