    What causes the size of a cavity to change when a metal plate is heated?

    The metal on the edge of the hole expands. This causes the ring to expand. Think of it like this. You have a bunch of metal molecules. Think of them like balls. These balls are placed in a ring and then super glued together. As the balls expand they have to move outwards. Away from the...

    Is Chi an Actual Force in Our Bodies and Surroundings?

    Chimps, I think the point here is that people are claiming Chi is NOT supernatural, but rather an undefined natural phenomena. And, based on personal experience, I believe that he was told how to exercise the Chi, but not what he would experience/feel. His experiences were then confirmed as...

    Mythology/magical tradition question

    I would look into the Kung Fu and Yogi traditions. While not traditionally classified as 'Magical', the descriptions of what a true master it supposed to be able to do frequently fits into those catagories. Some of the shaman type traditions might fit also. Totems and such.

    Any good sites on pig dissection and animal skulls? For zoology class exam help.

    A quick Google search on Pig Dissection brought up this result. http://www.whitman.edu/biology/vpd/main.html Virtual pig dissection with study guides

    Is Chi an Actual Force in Our Bodies and Surroundings?

    I don't understand the animosity that I am getting from the non Chi believers. It seems that they are against the idea that there may be something there. I thought the whole point of science was to question our beliefs and test for the truth. And even when we had a 'truth' to be sceptical of...

    Exploring the Photon Belt and Our Solar System

    There is no reason it shouldn't. Sort of like the moon orbits around the Earth with the combined system orbiting around the sun. Unless coriolis force has some affect, but I would imagine it is weak enough that it wouldn't.

    Medical Does arteries / veins have nociceptors?

    I would guess you have a better chance of feeling the effects rather than the bots themselves. However, the real answer would have to do with how small the bots are and what they are designed to do. Your blood vessels are filled with little biological machines. You don't normally notice them...

    Help Design a Human-Powered Helicopter

    Interesting problem. I would suggest starting with something that already exists, like a gyrocopter. And yes, I know they require forward momentum to get moving, but they are light and run on low power. If you could get the blade moving fast enough, you could achieve lift off. Stability is...

    Can Silver Be Scientifically Harmful to Werewolves?

    Since werewolves are fictional, you can have any reason for silver to be poisonous to them. It doesn't have to be an alergy. Depending on the nature of, or cause of, werewolveism (Not sure that's a word) different reasons could be valid. It could be that werewolves are caused by an...

    Cloak of invisiblity , what kind of applications can it be usefull for

    Microwave only at this point. It would be useful in removing interference from receivers and transmitters. I understand that they used radar absorbing paint on the SanFrancisco bridge. Instead of seeing the bridge, ship radar now sees the other ships. Something similar would be usefull...

    Is magnetic flux possible through an open surface?

    Yes it is possible. Magnetic fields travel through space. They like to travel through some materials better than others(Ferric), so you can guide them with the right material. Definition/Summary Flux sometimes means total flow through a surface (a scalar), and sometimes means flow per...

    Is it possible to harness energy from the earths magneic field?

    The idea of wireless power - with a "working" range of 1 meter would be ideal for EV's. Why not put a coil around the outside of a house. The magnetic field generated by electricity traveling through that coil will be the same at any point inside that coil. This magnetic field can then be...

    Explaining Alternating Current: How Does it Work?

    Alternating Current is generated as Alternating Current. It could be generated as Direct Current, but Direct Current does not transmit as easly or for as far. Some points needed for understanding this. Electrical current is generated by moving a magnetic field through a conductor. The...

    Does every object have capacitance?

    My understanding is: capacitance is the ability to hold an electric potential different than the electic potential of objects near it. In that case, all objects have the potential to have capacitance, they just need to either; a) be non-conductive or b) be electrically issolated from the other...

    Magnetize a steel wire by rubbing against your head. (BS or ~BS)

    I'm not sure, but the movement of the wire across the hair should strip electrons off the hair, giving the wire a static charge. This charge may induce a magnetic field. Although I believe only moving electric fields generate magnetic fields. In this case the charging (Charge moving into the...
