If there is nothing special about the fluid, what happens? Two half reactions are possible. Do they "get together" somehow?

You mean the ions already present due to the copper sulfate? What happens if the solution is conductive but not specifically loaded with copper? My original question concerned the role of the solution to the ability to corrode.

What does this mean physically to this system? So the copper ions are totally replaced by nickle ions. Where does the copper go? You imply that the neutral copper atoms are not soluable. Do they drop out at the point where the nickle was picked up? Or join with the bulk copper samples...

I have some questions concerning the tendency of a system containing two different metals and water to corrode. This is coming from several similar discussions on another forum, concerning water cooling of computer components. There seems to be a lot of repeated dogma, which may include...

The result was surprising. Their "explanation" was nonsense. What is the reason that the boat is able to move forward? To those who haven't seen it, they put a fan and a sail on a model cart or boat, and as expected, it didn't move. They made the sail very small and it moved backwards...

You are mistaken. This is the line of thought that led to Einstein's "Doesn't play dice" quote. But since then we have learned that there is genuine randomness. It is unpredictable and unknowable even in principle, and "hidden variables" have been ruled out.

If there were any such that had any effect on matter at normal energy, or even at the energy of fusion within stars, we would have noticed already. There may be extra bosons associated with various Unification ideas, but they would be very massive and have extremely limited range. For example...

Well, p is momentum, which is mv. E=MC² is for an object at rest only. It's not counting kinetic energy ½Mv², for example. For a massless particle, you don't have M at all, and the only thing you measure against is p.

No, the families are layed out due to how they interact, forming various patterns of relationships. As mentioned, the "first generation" has neutrino, electron, up, and down. They are all "matter", not anti. The Weak interaction treats the first two in the same way as the second two. The...

The Doppler shift is one thing (changing latency of getting the signal), and time dilation due to velocity is something else. They both exist, but are not the same thing.

To give a specific example, an electron and a positron are both fundamental particles, and are different and distinct species. They are related via symmetry. For virtual particles, you could say some reaction was due to an electron going one way or a positron going the other way. That is why...

"mispelled" is pretty bad, too. Firefox has a spell checker that automatically shows red wavy lines. I thought all browsers did that now? My favorite explanation: See http://arxiv.org/abs/physics/0302045"

See http://en.wikipedia.org/wiki/Quasiparticle" , especially the introduction. What does that have to do with fractional charges being strange?

If you were playing cards and got dealt a blue ace, would you think that is strange? Huh?
