Good guess but no, not an engineer. I write software, primarily on the mainframe. I don't expect it to be able to do it on one formula on a spreadsheet but that is OK. After I get every thing I want on there then I will begin making it look better and easier to use. Then I will hide all the interim results on another page or something. In the mean time, I use those results so that I can manually verify them.

That would be great if you look the formulas up. I know the rise in temperature formula was very simple. Seems to me it involved only the amount of kinetic energy to be absorbed and mass.

Thanks
