    Will a wet sheet become dry when hung outdoors on a freezing day?

    An interesting question. The thing is, yes it will freeze but then, ice also evaporates. When it does, it is called, sublimation. Of course, it doesn't sublimate at the same rate as if it was warm weather. Furthermore, the rate of sublimation will also depend on the relative humidity. If a cubic...

    what is the difference between air pressure and wind?

    The wind doesn't affect the air pressure, as such, but the difference of air pressure is what creates the wind.

    I can make the same predictions as the UK met office, but without a meteorology

    "there is a 50% possibility that this winter will be a cold one!" ... he, he! Very funny. Don't you see the humour in it? If it was American, I would wonder, but I find in that saying the typical British humour we've come tot love, on this side of the "little pond" (Norway, across the North...

    Air Pressure Quiz Tomorrow, Help?

    The air pressure is actually the weight of the air above us. On your finger tip (about a square centimeter of surface) the "weight" of the air is roughly one kilo. You don't feel it as such because the air being a fluid, you feel it also from the underside of your finger. The higher you get...

    If you had a completely enclosed truck with birds inside, would the truck

    You've already received answers saying yes, and others saying no. You must be confused. I'll add to that by saying: It depends on the type of bird! :-) A bird can be a colibri or an albatross. While they are both birds, the way they fly is entirely different. The colibri used the Newtonian...

    Nostradamus 2012 - What do you think?

    French is my mother tongue and medieval French is something I, unfortunately, had to learn at school. If you have any text from Michel de Nostredame (yes, that was his name) that talks about the year 2012, please send it to me. ... I am afraid you will never write! :-(

    Why is the shortest day the start of winter and not mid-winter?

    Goober has an interesting metaphore; me like it! :-) But, in more down to earth terms, two-third of the earth is water and that regulates the heat in such a way that there is a large delay on the seasons. But this varies also very much on where you live. A continental climate, far away from...

    why the human hunt gorillas?

    Because some hunters like to make ashtray from the hand of a dead gorilla. In turn, the gorillas make sure that the hunter dies of lung cancer and such get their revenge. Perhaps you may like this quote from "The Hitchhiker's Guide to the Galaxy," chapter 23, 1st paragraph. "Man had always...

    Infinity question?

    As Antons says, one has to differentiate between the abstract mathematical definition of infinity and physics. Can you say that the number zero has a physical existence? Your reasoning was already the point Planck made about light being a wave carrying energy. There is an infinite number of...
