re: #367 LudwigVanQuixote

Luckily, I went to Engineering school back when calculators were first getting very powerful so many of the professors banned calculators altogether from the exams rather than try to figure out who was using them to look up saved formulas or example problems. If you made the right assumptions and figured out the equations correctly, the math at the end was typically easy enough to do in your head. If the equations yielded some difficult math, you just knew something was wrong upstream.
