  1. I'm not convinced. I don't think being forgetful whilst talking, especially in public, is a definite sign of cognitive decline. That video is nothing more than a blooper reel. And Walker Bragman is a journalist and cartoonist not a neurologist. Not what I would call a credible source of information.

  2. Sigh no you have to recognize that harmonic, inharmonic and anharmonic are descriptives of the characteristics of the oscillator. Here is how classical harmonic oscillator is described. A simple harmonic oscillator is a sinusoidal oscillations about the equilibrium point, with a constant amplitude and a constant frequency (which does not depend on the amplitude). https://en.m.wikipedia.org/wiki/Harmonic_oscillator Note what stays constant An anharmonic oscillator n classical mechanics, anharmonicity is the deviation of a system from being a harmonic oscillator.

  3. It's reasonable to assume reality will continue to baffle a reasonable explanation...

  4. Personally I think there is a great mathematical beauty in String Theory, and a number of important advances in both mathematics and theoretical physics have emerged from the study of this model. However, “it’s beautiful” is not a scientific argument, and no indicator as to its value as a valid model of quantum gravity. One of the main problems I see right now is this - String Theory doesn’t actually produce GR in the classical limit, it produces GR plus a large number of scalar fields. There is no evidence for any of these scalar particles in the real world, nor is there any known way t

  5. Well from a personal view, I find that the quantum regime isn't weird once you remove classical viewpoints. Entanglements and wavefunction collapses obviously involve probability functions but the mathematics are similar to statistical mechanics.

  8. Isn't it the other way around? What we observe in nature is the weird looking stuff. And QM is the, or at least one, explanation for it? I do not see how you can take the observations that we make about the universe to not reasonably represent how the universe is.

  9. No that isn't enough. Rather than try to latex all the steps I will link a lesson plan. https://www.google.com/url?sa=t&source=web&rct=j&url=http://physics.gmu.edu/~dmaria/590%20Web%20Page/public_html/qm_topics/harmonic/&ved=2ahUKEwit56aWkffnAhUiGTQIHdHNDK8QFjAmegQIBRAB&usg=AOvVaw0Xj29xXrtC_pZ9_IruaD_p If you look at this the solution will depend on the particles principle quantum numbers. If I were to get the eugenenergies and eugenstates using string theory or QFT the solutions will vary however in all three the principles are the same for orthogonality con
