Artificial Gravity from Rotation

[e of pi]

Umm.... Could it be that John is joking, e of pi?

I suppose it could be though there's not emoticons or anything to show it. If he is, I retract the statement but recommend he be more clear in the future.

Also, if you keep accelerating at 1g, you will reach the speed of light in 354 days 

Actually, no. Its off topic though so take a look here:

On the topic of relativity (albeit of the other variety), you could generate artificial gravity through rotating super-dense masses too (gravitomagnetism). Mount them on the wall like clocks and there you go. Unfortunately the best we could do right now is something like 10^-14g with osmium disks...

Oh my everluvvin' garnêt.  Let me make one thing perfectly clear...[say it like Nixon]

I've suggested that there be a poll to remove the smiley thingies from the site.  It ain't funny if I have to explain it.

Y'know.  Like the dyslexic man who walked down the street and turned into a bra.  Or the dyslexic bluesman who went to the crossroads and sold his soul to Santa.  Never mind.

since space will likely use metric units

Not if I can help it.  We last discussed that issue in 1776, and chose imperial units of measurement.

I don't think you said what you think you said, since the metric system was only first adopted anywhere in France in 1791 so I doubt it was a huge issue at the Second Continental Congress. Also, as an engineering student in Ohio, I find that the metric system is much more sensible and easy to deal with, and that I actually groan when problems are assigned using Imperial units. I strongly believe that SI/metric is better for technical work, and I hope it dominates in space.

Certainly when one does calcs involving energy, SI is the way to go, being defined so that mass units are unambiguous.

But that's way different than suggesting that we try to convert the USA's entire industrial base for no particularly good reason.

Let's keep it on topic, friends.

There are many very good reasons to implement metric time.  Short term pain for long term gain.  btw.  I can't believe that the stimulous package you guys had didn't include going metric.  Trillions of dollars blowing around and it didn't even make the list???
