Re: Examining the Slit Experiment

Kickass ....
Thanks for your kind words. Its true that my last post was my first and that I have read very little of yours, or others posts on this forum.

I am not a Scientist and I know very little about maths. I will try a little more detail

Quote:
..KickAss ..Consider a simple correspondence fact about the photon and electron. They both have mass-energy and thus are identified as forms of matter.
If you consider the electron as occupying an 'orbit' or 'blur' around a nucleus, then only certain 'orbits' are allowed. A raw description of allowable 'orbits' would be that the 'diameter' of the electron must divide into the circumference of the orbit exactly, whether it be 10, 20 or 11 times. if an allowable orbit had a circumference = (ten electron diameters) then the next larger allowable orbit would be a circumference = (11 electron diameters)

Of course this is an explanation that does not exist in reality.... but it is conceptual.

Each time an electron gains or loses energy it 'jumps' to the next available orbit. Remember this 'jump' is not really describable as it is part of the probability of all possible paths. However, each time the electron does this it gives of exactly one Photon.

Electrons are massive objects, while Photons have zero mass (at least zero invariant mass ... which for our purposes is the same).

This difference can not really be considered minor. The reason I suggested electrons in the double slit experiment is that they are 'heavy' and travel 'slow' whereas a Photon, having zero mass zips along at Light(-ening) speed. Electrons are very easy to keep track of, look at the example of your TV screen or computer monitor if you still have the CRT type. if there was no barrier at all and we fired a single electron at the target it will register.

The double slit experiment was first performed many years ago, 1801-2, I think. Since then many, many times it has been proven. it has been followed by the Delayed-Choice double slit experiment...... If you have a problem with the double slit then be prepared to be outraged by the delayed choice. The most shocking implication is that the past can effectively be altered by the future.

All this culminated in an alienation between two camps ... On the one side Einstein, Podolsky and Rosenberg, known as EPR ... and on the other, all the new hot, young quantum physicists.

The EPR side threw up a challenge that absolutely stymied the QM camp in their tracks. The best answer they could come up with was that 'in the world of the Quantum such questions are not allowed' .... pretty lame, but from a scientific viewpoint perfectly valid.

The along come an unknown guy called Bell. He suggested a way that the EPR Paradox could be tested ... up to this point it had been thought impossible to test. In the early 1960s (or possibly late 60s) this test was conducted and guess what .... it proved absolutely beyond doubt 100% that the universe is not local, and that Classical mathematics is no longer the most valid description of our Universe.... it also spawned many false religions and cults as people read mystical things into it.

Once you have a handle on Bell's Theorem you will never look at reality in the same way again. You can be assured that Bell and the other physicists that successfully bought his ideas to experimental conclusion are people of immense skill and integrity. They can easily detect particles used in experiments from amongst the particles making up the machinery of the experiment..

KickAss ..Here is a challenge. Give me two seperate theories of matter. One classical and one quantum. Preferably from the standard model.
I am afraid that it will take someone a lot better than me to do that.

From my own personal opinion, I believe that in the beginning there was a fundamental substance (matter) that was somehow put in motion (energy) ... The Universe is the result. Once you have matter in motion you only need a Newton to say F=MA, an Einstein to correct the absolutes by fixing the Speed of Light relative to all observers, then go on to say that Gravity is nothing more than Acceleration and it is also fixed relative to all observers.... but finding out what that bastard fundamental substance (matter) is ... you will need Quantum Mechanics .... and there goes the neighbourhood..!!

Hypography?

Hypography [n.]: A combination of "hyperlink" and "bibliography" - ie, a list of links to electronic documents. Comparable to discography and bibliography, but not cartography.

We have been online since May 2000, and aim to be the best place to find and share science-related content of all kinds.

Share the love!
