A little fun fact.
Rub your hands together.
They're getting warm, aren't they? You've just changed the electron's energy state and the quantum number for each of those electrons.
But, the Pauli Exclusion Principle states that no 2 electrons can have the same quantum number. So that means you've just changed all the electrons around you, and eventually you changed the electrons from different galaxies.
Just by rubbing your hands. You've changed something light years away!

What's a quantum number?
User avatar #11 to #10 - hollyisthebest (07/09/2013) [-]
It's complicated to explain, so I won't bother trying. Just go Google quantum mechanics.
It's pretty interesting, if I do say so myself.

Basically describes a certain state of a particular quantity of that of an atomic entity whether it be spin, momentum or energy level. The values are typically either discrete integers or half-integers (basically nothing inbetween as opposed to continuous figures).

i tried rubbing my hands together but they kept sounding like they were farting

no, you'll just make the molecules vibrate.
but in replacement. I can tell you that in an interpretation of quantum mechanics, space is filled with negative energy electrons. under some circumstances these electrons jump to positive energy levels and leave a hole behind. the hole is called a positron!!

Also, any high school teen can tell you that if you add energy to an atom, an electron will shoot up to a higher orbital. A change in energy state, changes the quantum number, and Pauli Exclusion Principal states that no 2 electrons can have the same quantum number.

your hands are made of molecules, not any single atoms so let's start there. While adding energy to a molecule *does* result in an increase in energy level, it's unlikely to be an increase in the Electronic energy level as you described. This is because the energy gaps between electronic energy levels are quite large, and require more energy than rubbing for the promotion. Suddenfury is right, the relaxation from an electronic excited state would likely cause visible light emission too. But there are two other main types of energy levels besides electronic. Rotational energy levels have smaller gaps, but can't be considered here since the solid molecules in your hand aren't free to rotate (although the liquid water molecules might). What's more likely is that there's a excitation of Vibrational energy levels. An increase in vibrational energy level means the average speed of particles' motion increases as they vibrate faster, which is the same as saying increasing temperature. This agrees with the observed result: hand warms up.
TL;DR: Warming by friction is not from electrons or quantum numbers.

He used some incorrect terms. But the idea is still correct.
User avatar #19 to #16 - suddenfury (07/09/2013) [-]
not really, firstly you wont be raising any energy levels of the electrons that easily, otherwise you would be seeing light flashes from your hand. Secondly Paulis principle is about quantum states, the position is part of the state. so seperated electrons can have the same energy level. at least in QM, don't know about Quantum Field Theory.
still, entanglement could do some fascinating things
User avatar #20 to #19 - hollyisthebest (07/09/2013) [-]
First of all, it's a thought experiment. We didn't observe anything other than the diamond getting warm.
Second, he used energy state instead of quantum state to get people to understand the basics of quantum mechanics. You see, everyone automatically assumes that quantum mechanics is some super difficult thing that they should never ever try. Using energy state, people would be like "Isn't that Chemistry? Hey, this isn't so hard! I should learn more about this and impress someone."
And third of all, entanglement is pretty damn awesome.

Philosophy major here to make you doubt your free will.
Doing what you want to do is not the same as libertarian free will. You do what you most want to do invariably. But who or what determines what you desire? This is a particularly troubling question because you cannot be the thing that determines your strongest desires. For you must desire to change your desires if you could change your desires, which means that desire had to already be set inside you without your action being involved at all.
What, then, decides your desires?
If materialism is true and all there is to reality is the physical, then you're desires are decided by chemical reactions which were decided by your genes which were determined by evolution. Your desires are controlled and thus your actions are controlled.
"But I'm still committing these actions!" you say. Consider this: when you come to an opportunity for a decision to be made, you must act. You have no choice but to act. Not acting or making a choice is a choice in itself. In any set of circumstances you are propelled, outside of your free will, into making a decision. This decision, as already discussed, is determined by your strongest desire which is determined by your body.

If there is only material reality, you are no free. You are physically determined to do every action you have ever done just as a foot is destined to bounce by reflex after the knee is struck.

I think the fact that we are just a speck in the enormous Universe makes us incredibly significant, there are so many millions of planets without life and then here we are.

Look at these people, these human beings. Consider their potential! From the day they arrive on the planet, blinking, step into the sun, there is more to see than can ever be seen, more to do than— no, hold on. Sorry, that's The Lion King. - The Doctor
