    Newtonian vrs Relativity

    Ok my question is what did Relativity change about Newtonian physics? The way I see it, it didn’t really change much at all. It all has to deal with objects in motion or is there more? How does QM display both or only one of these styles?

    Can some one give a simple example of how Newtonian physics differs from relativity. I know of a few but I’d like to work with people here to expand my understanding. Thanks.

    Re: Newtonian vrs Relativity

    At low energies and low velocities, Relativity reduces to Newtonian Mechanics.

    It explains the changes from Newtonian models as you increase your mass/velocity as the interactions between the object in question, and a dynamic spacetime background.

    QM is built upon a Newtonian styled static and unchanging spacetime background.

    Re: Newtonian vrs Relativity

    So bent space-time cant be accurately described by QM?

    Also at what speeds or energies would you notice relativity changing Newtonian mechanics?

    Re: Newtonian vrs Relativity

    It isn't that it changes Newtonian Mechanics, it's that they start to diverge more and more as you increase the energies/velocities involved.

    QM doesn't deal with spacetime very well, at least as currently formulated, and it doesn't deal with resolving graviton > graviton interactions in a renormalizable manner either.

    Re: Newtonian vrs Relativity

    Thanks Max. So could I look at it as if Newtonian mechanics is just a fulcrum for a total relativistic view?

    (Supporting how one might..)

    That perhaps the quantum scale is still relativistic but the property of matter bending space-time distorts our results of the quantum scale. Just as gravity of galaxies in deep space distort our view of galaxies behind them. Every particle or location of matter would then change a result because of its vicinity, much like what is seen in the double slit experiment.

    Re: Newtonian vrs Relativity

    Newtonian physics was certainty until Hiesenberg proved him wrong. Einstien tried to grasp the certainty of measure too, with the movement of a train. He thought the speed of light was the only constant in the universe and his co-ordinate system the only way to measure nature. Quantum mechanics stole the show and sent us spiraling down the probable uncertain rabbit hole of the abiss. Beyond Newton and Einstien and QM is the truth of equality, someday all will see.

    I would say that I fear oneness, or total equality. Why because there would be no difference to measure and no division for evolution. God and the universe would be stagnant and that would just be boring. If you believe Hiesenberg then there is no complete measurement for equality because there would always be an outside, or perhaps inside, system that destroys, complicates or ruins equality. The same could be said about any type of measurement.

    Hiesenberg said a system is uncertain because there is always an out side system that changes it. However if you measure a buffer system constantly for changes from an outside system. Then the inside system will always be cretin, the buffer system will be probable and the outside system will always be chaotic.

    Re: Newtonian vrs Relativity

    I think Heisenberg hit upon a similar idea as I have, only he was looking at it from a different angle.

    Measurements are uncertain, because they can be affected both before and after you made/make them.

    You should have pointed out to him where he went wrong, after all, his results were uncertain.

    Is this your different angle ? Well .... at least we can do away with all those matrices.

    Uncertainty does not make something wrong, it just makes it uncertain...(no it's not an analytic proposition...).

    More like change the matrices to represent an extended temporal interaction period.
