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.

i assume you meant your wedding ring, rather than your wedding...;P i've recently found myself contemplating the shape of my wedding ring & any inconsistancies in place of staring off into space. unfortunately it tends to happen at work, where i have no micrometer. but class starts on wednesday...i'll have to wander down to the projects lab & measure mine. now you've got me curious!

Ooops, just so. Fixed. What class?

Well there's no need to get all bent out of shape over it.

All kinds of activities, including shoving one's hands in one's pockets, can 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 :-)

ha ha ha.

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).

This icon is my first wedding ring after I landed on it in a fabulous flying header while rollerblading. Whee! My husband at that point was already on #2, as he had to cut #1 off his hand when he accidentally crushed it in a moving accident. We gave up and ordered half a dozen online. With enough lying around we can usually find one that isn't too damaged to wear out of the house. Eccentric and somewhat scruffy: just like our relationship.

Doesn't eccentricity imply that your ring is a perfect conic section (and therefore a perfect, mathematical ellipse)?

I'm thinking it probably just gets that way through years of wear. And it probably wasn't micrometer-level perfect when you got it anyway.

You are an awful person.

PS: where's the control data from vix's? :)

Only you, Fish. Only you. Maybe it's just normal wear.
Saturday, September 16th, 2006 06:06 pm (UTC)
I'm certainly hoping it's *abnormal* wear. Keeping up appearances and all...

If you want, fish, I have a ring mandrel and a couple leather/wooden/rubber hammers, very nice for rerounding rings without changing their size.

ordered half a dozen online

Love it.

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

Yes, but how eccentric are you? Inquiring minds want to know.
Sunday, September 17th, 2006 05:13 pm (UTC)
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.)

radio communications...finally, my last last last class for my bachelors degree. i've been taking the scenic route! ;P

one of these days i'll come up with something interesting enough to post, i promise! (it would help if i were more writing-oriented to begin with, i suppose...)

*giggle*

Having only just come across this post, I shall submit mine for verification this evening.

However, I find the second statement of the original post to be a bit suspect...
