semiconductors have the property of a decrese in their resistance levels when they are subjected to high temparatures. so i think we can use this property and we can attain superconduction in semiconductors by increasing the temparatures. because, superconductivity using low temparature is a very expensive method and it cannot be implemented for general purposes.

Is there a theory for how the information about a changed state gets transmitted "instantaneously" from one particle to another?

I was told by my college professor that that there are an infinite number of points in any given area. A given area is finite. How can you have infinity in a finite area. I was told that a point has no size so there is infinity. If it has no size, It does not exist. The smallest thing known to man, and atom?? a photon?? has size. Some body please help my to logical pea brain.

I have been working on a theroy abouut a constantly repleneshing energy source. If you hooked up an electric motor and a turbine to a go kart, and used the spinning motion of the turbine to power the motor which would, in turn, make the turbine spin, would you be able make the go kart move with a single push?

We think of a 'thing' as existing based on the fact that it is made up of smaller 'things'. For example an apple exists because it is made up of atoms, the atoms exist because they are made up of protons electrons quarks etc, they in turn exist because (most probably) they are made of superstrings, that is about as far as we have got up till now, eventually however you must reach a point whereby there is a basic fundamental building block which exists just 'because it does' yes? and not because it is made of anything smaller. What do you think?

I'm sorry, I realize how elementary this is and I'm pretty sure of the answer but I just need to be positive.

Someone asked a similar question here and the answers were all contradicting, so please answer ONLY factually.
