Great minds

If you were to ask someone to describe how a park swing moves, you'd probably expect a fairly basic response. Something like "in a bit of a circle", "it swings back and forth", or possibly "like a pendulum".

Unless, of course, you asked two engineers. Not content with simply waving a hand back and forth and saying "a bit like that", an engineer would set about describing the motion mathematically.

That's not the sad bit though. The sad part is that even if an engineer cannot remember exactly what the formulae should be, they will attempt to work it out from first principles.
And if you've got two of them, each engineer only encourages the other to take it that little bit further.

Until you end up with this.
