Any engineer could answer this question because physics is mandatory.

High school physics is actually enough to answer this question if you paid attention. For me thermodynamics was the third physics course, so first year of Highschool.

This is like asking what is the square root of -1 and then someone claiming you need a doctorate in maths to answer this. Anyone who has read calculus knows the answer by heart and most who were awake in Highschool knows it too.

How hard was it to make the hubble corrections in space, such as the "contact lens" or the gyroscopes? I mean, it's super-sensitive stuff.
