Quantum Tunneling, An Explanation

http://www.encognitive.com
In quantum mechanics, quantum tunneling is a micro nanoscopic phenomenon in which a particle violates the principles of classical mechanics by penetrating or passing through a potential barrier or impedance higher than the kinetic energy of the particle.[1] A barrier, in terms of quantum tunnelling, may be a form of energy state analogous to a "hill" or incline in classical mechanics, which classically suggests that passage through or over such a barrier would be impossible without sufficient energy.

On the quantum scale, objects exhibit wave-like behaviour; in quantum theory, quanta moving against a potential energy "hill" can be described by their wave-function, which represents the probability amplitude of finding that particle in a certain location at either side of the "hill". If this function describes the particle as being on the other side of the "hill", then there is the probability that it has moved through, rather than over it, and has thus "tunnelled".

[red00devil]

is it false then that the fusion in the sun happens because of the immense gravitational forces due to the large mass of the sun? I'm not refuting anything... just curious...

@Mal1234567 orly? and what are these types you are talking about? ))

[Mal1234567]

@ActiveStorage Experiments over the last 2-3 years have shown that the type of detection equipment is irrelevant to the outcome.

[ActiveStorage]

@Mal1234567 thanks, i remember what i asked you and yes you dont know much about the detection technology)

otherwise you wouldnt make this post about "Piers Anthony's macroscope" and "Superman's super vision"

lol

[Mal1234567]

@ActiveStorage Clearly, you asked me if I watched a cartoon and then you stated that I don't know much about detectors and how they function. But it doesn' t matter if you use Piers Anthony's macroscope as the detector, it doesn't matter if you have Superman's super vision, the results are the same. Detection itself changes the particle smear.

@Mal1234567 clearly you are not reading my posts. im saying that the way we build detectors to detect elemental particles makes all the difference. not presence or absence of one.

[Mal1234567]

@ActiveStorage I've seen that cartoon, I've seen other videos on the net. The presence or absence of a detector makes all the difference.

@ActiveStorage well the existence of atoms were settled once and for all by einstein when he studied brownian motion. he said that the small grains moved like they have been hit by minute particles.

The duality is a bit hard to explain in this limited space that youtube provides. I suggest "In search of Schrodinger's Cat" for a start. Great book in my opinion.

[ActiveStorage]

@mignik01 yes we do treat atom as a probability cloud now. But weve been treating atoms as particles for thousands of years before that. Im simply saying that there is no real need for concept of duality. We treat atoms as particles cause it was the most simple and obvious thing human mind could think of and describe back then.

[ActiveStorage]

@mignik01 wrong. mass and spin have never been explained. theyve been observed and described. Not explained.

ps and the fact that matter is made of particles doesnt explain it anyway
