God wanted to give man something to play with
It's interesting that everyone pays so much attention to magnets. If they payed that
much attention to electrons they'd really be amazed. Electrons are what we interact
with in our nature. Everything we touch, hear, taste, smell, see, involves interaction
between electrons (or photons and electrons). Magnets illustrate the amazing
properties of these things very nicely as we can then get a feel for what effect
their spin properties has on our experiences, but we experience that same thing
when we touch something, yet the distances involved are so much smaller they
dont even seem like they are really there at all so billions of people live out their
entire lives and never realize that they had been interacting with every single
object in their lives because of the electromagnetic force (ie magnets).
"The universe is just a pile of electrons and photons, and nothing else matters"
If you could learn to manipulate electrons, you could do almost anything.
I have to admit that i've always liked magnets too, and electricity. I think of magnets
and the electromagnetic force a bit differently than when i was a kid, but magnets
are still great to have. I use one small strong one in one of my flashlights to keep the
positive contact connected to the battery. It works great.
I think the thing that always got me was that a magnet seems to have some sort of
force without actually doing anything to get that force. Once it has that force,
it always has that force. The problem is that it is deceiving, in that a force doesnt
necessarily mean anything gets done. We could have a strong force but if it doesnt
move anything it doesnt do anything except maybe hold something in place.
When we want to generate energy, we have to have it move something, and then
that requires more input energy.
Similarly, we could squash a strong spring with some screw clamps and it would push
quite a bit on the screw clamps, but it wouldnt do that much for us that way.
Ok, i got a little off the subject here, but when you talk about magnets, you talk about
electrons, and when you talk about electrons, you talk about everything in existence
I saw a program on an invisibility scheme, where a scientist worked out a method to
make something invisible using a special kind of material. How does it really happen?
By a special manipulation of the electrons in the material. By manipulating the
electrons in this way they no longer react to light the same way, so they take on different
properties that we as humans experience.
LEDs vs Bulbs, LEDs are winning.
