That'll do pig
Today I tried the flying pig practical with one of my first year classes. It took a lot more room that I had anticipated so I shortened the strings on a couple of the pigs so that they'd fly in smaller circles. Worked quite well I think. The only pair that managed to get the data processed in class got a value of 9ms-2 for g. Not bad for a pig of an experiment
I've been coughing all week so went to the doctor today to find out why. It turns out that I had swine flu. Thats what you get for spending to much time with pigs. That joke works much better if you speak Norwegian with an English accent because fly in norwegian is pronounced a bit like flu. Whilst I'm on a tenuous link I also noticed that πg is pig. The equation for the motion of the rotating pig actually has π and g in it, unfortunately they are not multiplied together. Shame
