i got another one

Current does not flow or travel in wires or electronic components it is the electric charge that flows never the current.

Yep – I would agree with that.. Thanks for the line.

uhh… which science teacher thinks saturn is the only planet with rings? Deserves a firing

and mike – no, you are still wrong. you can not get a cold JUST from cold temperatures. It can influence getting a cold, but so many people here are just wrong.

I remember an argument about icebergs destroying ships being a myth because iron is stronger then ice. I wisely stayed out of it… i’m not sure what to do. Shut up and don’t say my misguided science, or speak up so everyone can follow my views.

You could get a cold just from low temperatures.
Actually, that has recently been disproven. You are more susceptible to viruses when you are out in the cold because the blood vessels in your nose and mouth contract, allowing viruses that already exist in your nostrils to enter your bloodstream.

As far as i remember the sky is blue because of nitrogen and oxigen particals scatters short wave length light more so than longer wave lengths. (blue violate ect) Watter haveing a simuler effect to a lesser degree as the original post states…..

And yes objects do sink relative to the density unlessssss the displace the liquid they are placed in, or do not break the surface tension.

Did they know that the earth was spherical !!! Off course they did. Look up Eratosthenes, not only did he know that the earth was round he calculated it’s radius to 4% accuracy, the developed longitude and latitude … and there were others.

So last I heard, the sky is blue because water is blue and the sky reflects the color of the water… which is almost always some shade of blue. I’ve never read a book that claims water is blue because of the sky.

[shrug] *I* found it interesting, particularily the ‘blue water’ bit. Intellectually, I knew the gist of it, and tried to explain it to someone the other day, but couldn’t find the words. Got em now, thanks:)

So raff, p=m/V.. last i checked iron has a pretty big density, but a ship does not because its displaced volume is effin huge.
