Mar 17, 2009: Roundest Thing, Evah

xoxoxoBruce · 03-17-2009, 01:00 AM

Wolf came up with this item. It's a ball of fused quartz, and the most perfectly spherical object ever made by man.

Quote:

It’s only the size of a ping pong ball, but its surfaces are so smooth that were it blown up to the size of Earth, the tallest mountain would be only eight feet high.

Actually it's one of four.
Four? I'll buy making one to, you know, see if you can, but making four means they must have a use for them.
Yes, they go in a space probe.

Not the kind of space probe they used on Burt Campbell.

They're used in "Gravity Probe B", which has been up there a couple years now.

Quote:

Einstein's theory of General Relativity predicts that Earth, by rotating, twists space and time around with it, forming a mild vortex in the fabric of spacetime around our planet. Researchers call this "frame dragging." Most physicists believe the spacetime vortex is real, but no experiment to date has been sensitive enough to detect it unequivocally.

Enter Gravity Probe B.

They've wanted to test this since the 50s, but nobody had the balls.

Quote:

It was originally proposed 47 years ago (!!) — but was delayed for decades waiting for funding, waiting for the shuttles to be built to get it aloft, then discovering that, whoops, the shuttles couldn’t actually handle that sort of payload, then designing a rocket to finally get it aloft. They also had wait for all manner of engineering breakthroughs to make those spheres. But what a metaphorically lovely finale: The most perfectly round objects ever made by humanity, flying through the void on one of the purest scientific quests ever.

The whole complicated story can be found here, and here, where they explain all about the Gravity Probe B project...

EXCEPT, how they made the damn balls.

So round...

So firm...

So fully packed...

SPUCK · 03-17-2009, 05:49 AM

Wow.. They have a lot of balls!

I thought for a minute they had captured the terminator and cut his nuts off.

Hee hee.

This was a cool IotD. Thanks Bruce and wolf!

Bah! You want to see something REALLY round, check out my stomach the day after Thanksgiving.

Gravdigr · 03-17-2009, 12:20 PM

Probably the most expensive balls evah...

Read the wiki for a current timeline. What I read from the ending is that the results, although indicative of proving the space-time warp, will be too inaccurate to determine definitive results.

Nerdgasm.

Clodfobble · 03-17-2009, 09:29 PM

I want to touch it. What do you think something that smooth feels like?

Sperlock · 03-17-2009, 09:53 PM

Pinball, anyone?

Yes they do.

They're in the process of making the worlds fastest marathon runner.

Ball bearings and a stick shift
old, old joke

Make your own, instructions are here.

Requires four slightly wobbly sewing machine motors

Ah, thanks Beest. A ball grinder, I should have known, after all I married one.
