I recall my painful schoolies, especially my maths class when Mrs K used to 'help' me (with a ruler on my knuckles, 'ouch') remember that 'you couldn't get something out of nothing', though of course I would dispute her teachings today, given the magical maths of UMNO.
Then delectable Miss L taught me about the 'conservation of energy', that P.E would be converted into K.E or even heat energy, or as I jumped off the springboard at the Penang Chinese Swimming Club, into one mighty big splash (and a chewing from the lifeguard), BUT the sum of all the (various forms of) energy should remain the same.
With this background maths philosophy, I worry about the current airline price war. I've blogged on this issue in Scorpion-like airline price war? over at BolehTalk. We know what the scorpion is like, don't we?
