Discuss about Quantum Physics here. *Start up* Yes, I created this because I am ridiculously bored...Hopefully it will last... or even GET alive.

IDK T^T I SHALL GUESS..... Q = charge e = electronic charge (a constant) n = number of electrons in whatever you want the charge of IDK :( :( :( -

I'm with Einstein so I say it's kinda lame

You want to discuss Quantum Physics yet you have no idea about Quantum Physics? Let me use this thread to promote my new book "The 3rd trimester and what to expect".

I think we first must establish the abstract vector space in which we will be working in for this discussion first. http://en.wikipedia.org/wiki/Hilbert_space I found the fact that there was no mention of this in my quantum course a bit disturbing. It quickly turned into a regurgitate a bunch of equations with no chance of discussion.

The experiment that started it all was one where a charged metal piece was exposed to higher intensities of light and the charge before and after the exposure was measured. Because you could see that the charge went down significantly, Einstein assumed that light was not only a wave, but also showed characteristics of a particle. So Einstein postulated the photon, a massless very small concentration of energy that interacted with the electrons, pushing them out of the metal and thus reducing the charge.

Quantum mechanics finds its origins in explaining spectra of elements. http://en.wikipedia.org/wiki/Balmer_series This was proposed when Einstein was only 6... Einstein is known for general and special relativity not quantum mechanics itself, although his theories helped develop it a lot. -

Everyone who posted in this thread should really Google 'D-wave' and take a look at that shit! :jawdrop:

Ok pardon me what I meant to express is that the dualism is the first important discovery to be made. -

Is it really? It's hard to say any discovery was the most important to be made in the development of quantum theory. :dunno: Think about: -Scientific method -Discovery of the elements -Principia Mathematica -Opticks :dunno: -

Going to start with QM next year, keep the discussion going.

Anyone who has dealt with quantum physics knows that the dualism is pretty much the most important discovery there. It's the one thing that makes the difference between macro-physics and macro-physcs. -

But where does that story begin? Or, where is the most important point in that story? :hmm: -

You stupid or something? I already wrote that the dualism is pretty much the one discovery that makes the huge difference between macro and micro-pysics.

The fact that things behave in quanta is the major defining point. Furthermore the fact that things aren't continuous is what gives rise to that duality stuff. Its kinda ridiculous to say that dualism is more important then the postulates that its founded on. Its called [B]quantum[/B] mechanics for a reason. -

Yes, but you didn't write why. I think there's a better argument for what Awesome is saying. The discovery that light is made up of photons, which are discreet packages of energy is far more important than duality. -

You stupid or something? Dualism means that particles also have wave-character or waves also have particle-character under certain circumstances. Dual -> two Dualism -> two states It's not called dualism anymore for some stupid fuckreasons, but it's meaning should still be clear.
