Tried this once, didnt figure out ANYTHING, just stared at some spaceship in empty space while navigating some config menus I didnt understand at all. Ragequitted after half an hour cause nothing happened. But this trailer was pretty awesome.

Gravity still exists, and exerts exactly the same force on you independent of whether you are standing on solid ground or falling, and whether you are falling inside an elevator or in empty space. The difference is the opposite force exerted on you by the ground vs no opposite force (except the tiny force exerted by air if you're freefalling in the open air). It is this opposite force you 'feel', while acceleration due to gravity without any opposing force feels like floating.
So a man in a free-falling elevator in an atmosphere WOULD feel a tiny bit of gravity, because the outside air would slow the elevator to less than terminal velocity, so it would slow down slightly, unlike the mans descent, making him fall/float to the floor of the elevator eventually and then feel a microgravity exactly equal to the force exerted by the air.

I remember meditating as a teenager. I found my consciousness shrinking into a tiny sphere. My head was a vast empty space, miles in diameter. Did it make me a better person? Who knows.

I work in a CNC machine shop programming lathes. That isn't aluminum they are machining. It's definitely steel, probably 4340.

Carbide inserts are more than capable of cutting metal without coolant. Well formed chips absorb and carry most of the heat away. You start to run into problems with gummy materials (like aluminum) that form a built up edge on the cutter. In this case high pressure coolant can be used to help break the long stringy chips and keep them from sticking to the insert.

One case where using coolant can be detrimental to tool life is when machining a part with an interrupted cut. Think of sliding your finger over a surface with a bunch of holes in it. Your finger switches back and forth between making contact with the surface and gliding over empty space. In the machining world, this motion would cause abrupt transient temperature changes, and coolant can sometimes exacerbate the problem and cause the carbide insert to crack or chip.

(pedantry) I would hesitate to call that machine a mill. You can see the machine switching freely between rotating the part to provide the cutting force (turning) to rotating the tool (milling). It's more akin to a horizontal turning center with a milling spindle built in as well. Pretty awesome stuff! (/pedantry)

Actually,, atheism is the lack of theism, not the opposite. A good analogy was posted above, baldness is not the opposite of hair, or even the opposition of hair, it is simply the lack of hair. A semantic difference to be sure, but an important one if you wish to truly understand the terms.
edit: perhaps a better analogy would be 'the opposite of matter is not empty space, it's anti-matter'. Atheism is being empty of theism, not necessarily against it.

"Magnetic field ... with empty space between the tread and alloy wheel."

What!?! Because that wouldn't be excessively heavy/expensive/dangerous at all, oh no. I can't decide whether this should be in commercial, scifi, or parody.

This may already be mentioned (TL; DR) but when browsing on My Nexus 7 tablet, I don't see page controls allowing me to go to the next page. They show up on my Samsung Galaxy S3 though.

Also I get a bunch of empty space at the end of each page (after the content, but before the footers).

I submitted this video:
http://videosift.com/video/Tony-Kushner-Lincolns-Political-Battles
from MSNBC. In the olden days Vs expanded videos from this site it fill the whole Vs video box. This one is leaving empty space to the right and bottom.

Thanks lucky, better you than me.

I should add my congratulations to what must have been a huge effort to revamp the site.

BTW I just had an idea - I saw something neat on the revamped Basecamp application by 37Signals.

You can double-click on empty space to instantly jump to the beginning or end of a page. Might be useful for a site with long listings.

This vid isn't working for me.
The ad and the vid start at the same time. The ad is over the vid and the sound of each plays at the same time.

So I have to wait for the entire ad to end then when it disappears, I can hear the video but I only see a big black empty space.

Edit: found it on the CBS site: http://www.cbs.com/shows/late_show/video/2280813911/david-letterman-president-barack-obama

Complete tangent, but the "atoms are 99.99% empty space" always threw my head for a spin until I watched some PBS show with Stephen Hawking (Stephen Hawking's Universe perhaps?) that talked about strong and weak atomic/nuclear forces. Really answered the questions I had like why atoms can't just pass through each other if/since they are 99.99% empty space and therefore would be unlikely to physically collide. Cool stuff!

Just wanted to point out the mathematics of reducing the plate size from 12" to 10".

Measuring my own plates (which are 10") I noticed that the border for the plates is approx 1.5" wide, which reduces the effective area of the plate by 3" diameter.

A 10" plate will have a 7" effective diameter, and using pi*r^2 we have an area of approx 154.

A 12" plate would have a 9" effective diameter, and calculating it's area we get approx 254.

A 10" plate is 40% smaller in effective area than a 12" plate, so to me it's actually surprising that there is only a 22% reduction in food consumption (which can probably be explained by the psychology of perceived portion sizes and wanting to fill in the empty space of a plate).

....why didnt the big bang need a cause?

The theoretical physicist who most recently takes this question head on is Lawrence Krauss, you can see him do a lecture on this topic here
http://www.youtube.com/watch?v=7ImvlS8PLIo
He has also written a book about this subject since the video drew a lot of attention: http://ww
w.amazon.co.uk/Universe-Nothing-Lawrence-M-Krauss/dp/145162445X/ref=sr_1_1?s=books&ie=UTF8&qid=1337434114&sr=1-1


Quantum mechanics is still a cause, even if the universe itself was born from a quantum strangeness, its still SOMETHING. This is vastly different from no cause at all.

Krauss' talk is to lamen understanding of nothing....ie apparently empty space with still yet something there (the laws of nature have particles and anti particles popping in and out trillions of times a second!!!) This is still not nothing.

Still havnt explained it well enough to qualify that as saying - there was no need for a cause. QED is still a cause.

One of my first cars was a hand-me-down Toyota Camry that my parents bought close to the first year they were made. I remember that before it became my car, it broke its timing chain causing it to be dead in the water and required a tow to fix. I don't think that caused any collateral damage when it happened, it just died. Seems like that is likely to mean that it wasn't an "interference engine"?

It seems like having a non-"interfering" engine would be a very desirable thing, to limit the potential damage caused by a broken timing belt/chain. Why isn't that standard design? Takes up too much physical space? I remember when the hood of a car used to have a whole lot of cubic area of air/empty space inside, and now it seems like everything is designed to jam pack in there and fill it to the brim. Or is there some other major engineering or design challenge that makes that difficult/impossible?

Not to sound like a viral ad, but that early Toyota Camry served me real well. My family got 220,000 miles out of it before a CV joint died that it wasn't trivial to find a replacement for. We ended up handing it over to a junkyard at that point since we couldn't track down the part. A local Mexican handyman bought it from the junkyard and either found the part or homebrewed some other solution, and for all I know it could well still be running and up into the 300k+ miles.
