slightly eccentric

[gfish]

I just measured with a micrometer, and my wedding ring has developed an eccentricity of 0.3303 (24.4mm x 23.03mm). Which is rather odd, because I always take it off when I'm doing the kind of things that would tend to crush small loops of soft metal.

Okay, I pulled out my trusty old vernier calipers... I tend to not be so good about taking it off, but mine is only 0.04 mm eccentric. I guess that means you're almost an order of magnitude more eccentric than I :-)

An order and a half, by my calculations.

eccentricity is unitless and equal to sqrt(1-b^2/a^2), not a-b (where a is the semimajor axis and b is the semiminor axis).

Proving once again that I am clearly a moron at 1:35 AM.

Yes, but how eccentric are you? Inquiring minds want to know.

Apparently, not very. Only 0.05934. Now, I would call that less than one order of magnitude less eccentric, but I'm sure I'll get corrected on *that* too... (To be precise, 0.7455 orders of magnitude less eccentric than fish, but since orders of magnitude are typically integers, one whole order of magnitude less.)
