Comment Tablemate II (Score 1) 276

I have used a Tablemate 2 with my laptop for a few years now... yes, you may have seen the infomercials, and i believe they have them for sale at BB&B... The height and desktop angle are adjustable, and there are two front legs configured so you can pull it up to you on the couch with the feet going under the couch. I find it pretty comfortable to use, although in a few years i think the heat of my laptop has caused the plastic desktop to warp a little... Check one out, you might like it!

Comment Density (Score 1) 682

Something being "real easy to test" does not make the test accurate or significant.

In your discussion, you're talking about volume. However, the relevant topics are not volume, but density and mass. Objects 'float' when they displace an amount of the fluid (water) with a mass equal to their own. In other words, a 100 ton iceberg floats when it raises the water level by whatever volume 100 tons of water is.

So, the iceberg in a solid state will raise the water level by 100 tons of water (divided by the area of the pool and all that). When you melt the iceberg, you have 100 extra tons of water... so an equal rise.

It should be noted that this is primarily applicable on the north pole, where the ice is actually floating. Antarctica, being an actual land mass, has ice that is not currently displacing sufficient water to float.
