Explaination of duality theory ?

    explaination of duality theory ?????

    relativity phenomenon is largely based on the duality principle . the davisson and germer experiment proved the wave nature of electrons . however i wish to understand the cause of it .

    Re: explaination of duality theory ?????

    Not that I'm aware of. Which duality principle are you talking about?
    Wave-particle duality perhaps? This is not particularly a relativity thing.
    Why does it have to have a cause?

    Wave-particle duality comes out of the way physics has historically been researched - the duality is in the physical models and not reality.
    [We are like the three blind men investigating the elephant - "it's a rope" cries one, holding the tail; "no it's a wall", cries another, patting it's flanks; "nonono it's a snake" cries another wrapped in the trunk; the first two getting together may decide that an elephant has rope-wall duality - but actually it's an elephant.[*]]

    In nature, an electron is an electron is an electron ... it is itself and not a wave or a particle. The wave and particle models are just a mistake we have realized we were making. So what causes mistakes?


    [*] in the corrollory - the wise man being investigated by three bind elephants - the elephants get a more consistent view of humans: all humans, they conclude, are flat.
