Okay, listen up, and stay unazn, because entropy is a hard to understand topic.
First, something you have to realize that, like temperature, entropy is something we defined. So if it seems vague, that's only because in its original form, nobody who didn't take a university level thermodynamics course will understand (and a lot of who did still don't).
Entropy, in its simplest explination, is the measure of chaos in systems. Think of it as thus, take a container and pour sand in there with two different colors, both on either side, no crossover. Now you shake that container. The chance that the sand will come out mixed, with chaotic patterns, is far greater than the sand splitting in the same equal sides as before. That chaos is the form of entropy in this system. Shaking the container will only increase the entropy, and, at the best, the entropy will stay the same. Shaking the container will never make the sand more ordened. Therefore the entropy in a closed system can only increase or stay the same.
My third point, I say an closed system because that is a very important thing in entropy calculations. Entropy is often connected to temperature. As chaos is entropy, and molecules are most steady at low temperature, you can see why. Newton's third law states that the entropy of a crystal with perfect ordening, at a temperature of 0 Kelvin, is zero, because you exactly where each molecule is at every time. The system is ordened.
Now you ask, but why can't entropy decrease? I can take away heat through a fridge. That is because how you define the system. If you take the fridge and the room it came in, the entropy will only increase as it uses electrical power. (entropy usually takes into account the decay of higher forms of energy (work, electrical, etc) into lower ones (heat))
If you take the system inside the fridge, it cannot be a closed system, and the entropy of an open system can decrease.
This was another episode of Dennis teaches. Now go away.
"Jesus did it" is easier so that's what I'm going with.
I didn't know where else to post this sorry
Don't disgrace physics with your gay tendensies.
I like magic. BTW before I read that as his super powers, I thought he was just able to do anything that is within the realm of physics. For example it is theoretically possible to change atoms to other atoms by adding and removing electrons (whatever shut up) - but it's not possible to reverse entropy or transfer energy outside of the system.
This thread is now about Dr Manhattan.
So how about that big, blue penis?
I'd make myself not blue, probably before anything else.
