@pikilily , you just knew I'd have an answer, didn't you? Anyway, it's a mathematical representation of your energy levels (E), being equal to your MS energy level being reduced by 5%, when the temperature increases by 1ºC approximately. I'm not sure whether the ÷ 5% is a correct notation, or am I being picky? :wink: PS I was struggling with the division symbol, but not with the degree symbol!

There was always this equation explanation :- The angle of the dangle is inversely proportional to the heat of the meat, provided that the maxis of the axis, and the gravity of the cavity, remain constant. Also explained as :- In algebra, the angle of the dangle (x) is necessary to find y (the heat of the meat) provided that the maxis of the axis (graphing in y=mx+b) and the gravity of the cavity (solving inequalities) remain constant. If you use this in algebra and you have a dirty mind, I guarantee you will get an A*. It helped me pass Maths when I was at school (before they had calculators :???: ) !!
