Re: Wow, just wow

Mind-boggling stuff.

Re: Wow, just wow

Re: Wow, just wow

To think that it was first theorized in 1905! By some guy.

Re: Wow, just wow

hmmm, seems strange it's only in nature communications if it's so fancy... I'm gonna read the actual paper

Re: Wow, just wow

Don't need to read the paper, this is what it is

Re: Wow, just wow

That^, as simple as it may sound, is the postulate of Quantum Physics.

Re: Wow, just wow

really interesting, but can people actually apply quanum physics nowadays? as far as i know today all this is at the early experimental stages at best

Re: Wow, just wow

Scanning tunneling microscopy uses qm electron tunelling to image individual atoms every day in labs all over the world.

Re: Wow, just wow

Transistors are a consequence of QP.

This is not theory, they perform these experiments in undergrad physics classes to show this behavior. And the double-slit experiment highlights just the wave-particle duality of nature. There are other quantum mechanics principles which are witnessed and are being experimented on such as quantum entanglement are being used as a potential future for communications protocols.

Quantum physics as a whole has yielded a whole bunch of great inventions for humanity, the ones that immediately jump to mind are MRIs and FMRIs and are giving unprecedented views into the human body for medicinal purposes.

Read up even on Global Consciousness project, very interesting with what they are learning from it.

Of course and all things Sci-Fi / Star Trek will eventually become reality as more studies and discoveries are made in this field.

Re: Wow, just wow

From Wikipedia

[QUOTE]Applications of quantum mechanics include the laser, the transistor, the electron microscope, and magnetic resonance imaging. A special class of quantum mechanical applications is related to macroscopic quantum phenomena such as superfluid helium and superconductors. The study of semiconductors led to the invention of the diode and the transistor, which are indispensable for modern electronics.

In even the simple light switch, quantum tunnelling is absolutely vital, as otherwise the electrons in the electric current could not penetrate the potential barrier made up of a layer of oxide. Flash memory chips found in USB drives also use quantum tunnelling, to erase their memory cells[/QUOTE]

Re: Wow, just wow

All the crazy quantum phenomena have been recreated in a laboratory, even the ones that are REALLY crazy,like the Quantum Entanglement.

Re: Wow, just wow

thanks, will have to read more on the subject

Re: Wow, just wow

A fellow spaghetti is the lead researcher!

This is beautiful:

[QUOTE]A pulse of laser light is fired at a tiny metallic nanowire. The laser adds energy to the charged particles in the nanowire, causing them to vibrate. Light travels along this tiny wire in two possible directions, like cars on a highway. When waves traveling in opposite directions meet each other they form a new wave that looks like it is standing in place. Here, this standing wave becomes the source of light for the experiment, radiating around the nanowire[/QUOTE]

We once had a drunken discussion about this wave-particle duality thing for hours...you might have loved it, my wife certainly didn't. ..

Re: Wow, just wow

I certainly would have, I have these all the time with a couple of close friends here in town whenever we get together. And it becomes even more intriguing when you keep running into bizarre stuff like this

Re: Wow, just wow

so what is this wave thing, while I understand particles, I can't really wrap my head around the wave phenomenon (the wikipedia doesn't help that much, the language is a bit too technical for me)

but is it like time and space correlation?

whenever I think of energy I imagine a flock of microscopic charged particles, but looks like it has more to do with movement than the mass, am I on the right path here?

Re: Wow, just wow

the best way to think of this shit, in my opinion, is that things like light are neither particles or waves. They are something else entirely that can only really be described by quantum mechanical equations. Then, when we do an experiment to probe it's properties, what we see depends on the experiment we do. We can see it behave LIKE a particle, or LIKE a wave if we want. We then take our observations and relate it to something on a macroscopic scale that we have really well characterized, i.e. particles (i.e. projectiles like balls, bullets etc.) and waves (e.g. sound waves or waves on the sea).

Re: Wow, just wow

^^ what he said

Essentially, (if I have understood this right), when not observed (in the simplest way to describe setting up the experiment to see where an electron really is), an electron can actually exist in 2 or more places at the same time. When people read this, they don't think it's such a big deal but you have to realize, it would be similar to saying that when no one is looking, there are two of you sitting and reading this. The electron is a wave of potentiality in that it exists in multiple places at the same time.

But when the observation is setup to detect where the electron really is, you find that this wave of potentials (i.e. potential places where the electron could be) suddenly collapses and it ends up being exactly in one spot. But even then, you won't know where that spot is, until the electron were to collide with a detector and leave its imprint.

That's why quantum mechanics is so confusing because it could be anywhere to begin with and even when it's only in one spot, you can never determine where it will end up until you actually observe it there.

This is light years away from classical physics because even if you are blindfolded and you throw a baseball with a certain speed, you don't need to look at the baseball to detect where it will land. You can accurately calculate it without looking at it.

But quantum physics is nothing but probabilities. It will "probably" end up here, but no one can accurately say it will.

And this is just one of the mysterious properties of the quantum world.

so there are no actual particles and waves, then what are they? our imagination?

this is disturbing :oops:

Re: Wow, just wow

This stuff we are discussing is called the Copenhagen Interpretation. There are tonnes of "Copenhagen intepretation made simple" articles around. I would recommend reading a few until you find one written in a way you can get your head around

[QUOTE=yerg;1156356]so there are no actual particles and waves, then what are they? our imagination?

hmmm...this gets complicated pretty fast. The QM equations utilize something called the "wavefunction". This describes the thing we are interested in entirely, but it's not something we can measure directly. All we can do is do experiments which allow us to see some parts of it. It's a bit disturbing, i agree, but you get used to it :-)

Re: Wow, just wow

ok thanks, I'll read some more then

always interested in this topic.. thanks Kamal, looks like I have some reading to do :)

Strangely, Kamal hasn't posted about the quantic theory of the origins of the Universe, with NO Big Bang.
