    A Jewel at the Heart of Quantum Physics

    A Jewel at the Heart of Quantum Physics

    Artist’s rendering of the amplituhedron, a newly discovered mathematical object resembling a multifaceted jewel in higher dimensions. Encoded in its volume are the most basic features of reality that can be calculated — the probabilities of outcomes of particle interactions.


    Physicists have discovered a jewel-like geometric object that dramatically simplifies calculations of particle interactions and challenges the notion that space and time are fundamental components of reality.

    “This is completely new and very much simpler than anything that has been done before,” said Andrew Hodges, a mathematical physicist at Oxford University who has been following the work.

    The revelation that particle interactions, the most basic events in nature, may be consequences of geometry significantly advances a decades-long effort to reformulate quantum field theory, the body of laws describing elementary particles and their interactions. Interactions that were previously calculated with mathematical formulas thousands of terms long can now be described by computing the volume of the corresponding jewel-like “amplituhedron,” which yields an equivalent one-term expression.

    “The degree of efficiency is mind-boggling,” said Jacob Bourjaily, a theoretical physicist at Harvard University and one of the researchers who developed the new idea. “You can easily do, on paper, computations that were infeasible even with a computer before.”

    In fakt 20th century so-called physics haz no theory of particle interactions. And hencely some sort of new math trick iz of no help to real physics.

    "......The revelation that particle interactions, the most basic events in nature, may be consequences of geometry significantly advances a decades-long effort to reformulate quantum field theory, the body of laws describing elementary particles and their interactions.

    What a lot of krapp. The standard model of the atom iz krapp -- it iz mainly math -- and now mathematicians say that the physical world iz due to the existance of math geometry. They werent happy with just uncertainty and probability and tunneling and 11 dimensions etc.

    There are no standard laws describing standard elementary interactions.
    Mass?? -- u get that from a special particle.
    Gravity?? -- u get that from a very special particle.
    The strong force?? -- u get that from a special particle.
    Gravity?? -- duznt exist, it iz due to bending of nothing and bending of time.
    Particles?? -- theze arize from from very small stringlike equations.
    What a load of krappymathics.

    If u want to learn about real relativity and aether then google cahill and crothers.
    For the real universe and aether then google ranzan.
    For some interesting atomic theory google mathis (some iz silly, some iz good)(unfortunately mathis beleevs einstein).

    Yes, they would love to reformulate -- koz standard theory iz little more than formulas, the way to improov standard theory iz to improov the formulas.

    They say there iz no aether -- but they say there iz fields. And their fields are virtual fields -- ie imaginary math -- mythymatics.

    A body of laws describing hundreds of particles and their interactions?? Not really. None of their laws describe anything much at all -- mythymatical inventions of particles, with zero real description of any interactions.

    Today's scientists have substituted mathematics for experiments, and they wander off through equation after equation, and eventually build a structure which has no relation to reality. (Nikola Tesla)

    The skeptic will say: "It may well be true that this system of equations is reasonable from a logical standpoint. But this does not prove that it corresponds to nature." You are right, dear skeptic. Experience alone can decide on truth. ... Pure logical thinking cannot yield us any knowledge of the empirical world: all knowledge of reality starts from experience and ends in it.
    (Albert Einstein, 1954)

    Some things that satisfy the rules of algebra can be interesting to mathematicians even though they don't always represent a real situation. (Richard P. Feynman)

    It is inconceivable that inanimate brute matter should, without mediation of something else which is not matter, operate on and affect other matter without mutual contact. ... That gravity should be innate, inherent and essential to matter, so that one body may act upon another at-a-distance, through a vacuum, without the mediation of anything else by and through which their action may be conveyed from one to another, is to me so great an absurdity that I believe no man, who has in philosophical matters a competent faculty of thinking, can ever fall into it. So far I have explained the phenomena by the force of gravity, but I have not yet ascertained the cause of gravity itself. ... and I do not arbitrarily invent hypotheses. (Newton. Letter to Richard Bentley 25 Feb. 1693)

    One does not, by knowing all the physical laws as we know them today, immediately obtain an understanding of anything much.
    I love only nature, and I hate mathematicians. (Richard Feynman 1918-1988)

    ... the progress of science has itself shown that there can be no pictorial representation of the workings of nature of a kind that would be intelligible to our limited minds. The study of physics has driven us to the positivist conception of physics. We can never understand what events are, but must limit ourselves to describing the pattern of events in mathematical terms: no other aim is possible .... the final harvest will always be a sheaf of mathematical formulae. These will never describe nature itself, but only our observations on nature. (Sir James Jeans, 1942)

    One cannot escape the feeling that these mathematical formulas have an independent existence and an intelligence of their own, that they are wiser than we are, wiser even than their discoverers. (Heinrich Hertz)

    ... it would be better for the true physics if there were no mathematicians on earth. (Bernoulli)

    God forbid that Truth should be confined to Mathematical Demonstration! (Blake)
