It is well known by everybody else that if you repeatedly make the same mesurement on the same test piece with the same equipment you will obtain a range of results.

That is why you have been advised to study the statistics of measurement.

Following your reasoning that would mean that the physical object being measured is not the same object at each measurement.

This is false reasoning.

That is why the following conclusions are not justified by the premises.

1 + 1 = 3 for sufficiently large values of 1.

That seems to sum things up.

I once knew a physics major who dropped his trousers to count to 11 ... his girlfriends were always impressed.

I knew one that had "SWAN" tattooed on #11.
When 11 increased, the tattoo became "SASKATCHEWAN"...

Jeez.. I can't even imagine putting a ton of work into a thesis for it to fail. Must be tough to get back onto the horse. Interesting story though with a good lesson.

You are completely ignoring manufacturing tolerances. In other words, your "cylinders" aren't cylinders.

It gets worse. I've recently been looking into it again (just for the review) and found out I did the calculation wrong. The answer is still "no" but apparently no one checked. Including my mentor! Still, I'm going back through it and I'm getting some good education about where and why my work was wrong.

Once I am satisfied I can do the problem correctly I'm going to use a new method (well, new for me anyway) using "background fields." It should give me an answer in a matter of days, whereas before I had to work a solid year on it.

Hey, I'm learning. That's all I care about.
