Superconductivity
Beginning of paper
INTRODUCTION
We've all heard about . But, do we all know what it is?
How it works and what are its uses? To start talking about , we
must try to understand the how "normal" conductivity works. This will make it
much easier to understand how the "super" part functions. In the following
paragraphs, I ....

.... called ions. Electrons occupy energy
states. Each level requires a certain amount of energy. For an electron to move
to a higher level, it will require the right amount of energy. Electrons can
move between different levels and between different materials but to do that,
they require the right amount of energy and an "empty" slot in the band they
enter. The metallic conductors have a lot of these slots and this is where the
free electrons will head when voltage (energy) is applied. A simpler ....
