Hey JesseM, I see your point with 2. but I think 1. is closest to my answer. 3D spacetime of a 2D flatland universe is exactly what got me stuck. But I don't quite understand what your saying with 1. Can you please elaborate? And if I ask you how many dimensions we live in, how will you...

Thanks belliott4488, I did have a GR undergrad class with Hartle's book, Gravity, but we never did anything with imaginary time. I've thought about that before as it's easy to see how that can accommodate the minus sign in the line element. But then this seems to state that the 4th dimension...

Thanks, it did. But can't we argue that same picture with Newtonian mechanics? We draw worldlines the same way with Newtonian mechanics, but the total displacement is different. With light, how can the total displacement be zero in such a flat plane that moves through a higher dimension...

I'm confused about how to understand the ct dimension. I cannot get passed thinking that physically real dimensions mean more degrees of motion. If a flatlander went to the store to buy a can of Coke, the closed container would be a circle. The container is closed simply because there...

Uppercase psi, which is the full wavefunction, including the spinor, is symmetric when your dealing with bosons. Cooper pairs are coupled electrons that form a boson state. Covalent bonding is not Cooper pairing but the exchange force.

The quantum mechanical exchange force from the overlap of wavefunctions establishes the covalent bond. The expectation value of the square of the separation distance between two particles for identical particles is different than distinguishable particles. Identical particles can have an...

I researched this slightly and found this Nimtz has been at this for at least 10 years! G. Nimtz: www.public.asu.edu/~strato/Internet/Evanescent modes G Nimtz.pdf His only collaborators. Notice the title. www.public.asu.edu/~strato/Internet/Photonic tunneling Z Wang.pdf I don't...

I only made it to about 10 minutes into that video. It's too MTVish with a lot of sloppy statements. :)

I meant to come out swinging and show that the Minkowski metric is one “event arena” for GR, not the sole one. Thus, him claiming GR is irrelevant and therefore the photon doesn’t exist. ? I didn’t think I was making bold statements with my examples and I didn’t mean to imply the Minkowski...

There is no metric for the Universe. And certainly, the perihelion of Mercury was not calculated with the Minkowski metric. And unquestionably, GPS systems do not use the Minkowski metric. The Minkowski metric is GR’s special case in which one has Newton’s Laws and a finite speed limit theory...

muh, Since QM has wave solutions, like analyzing any properties of a wave, there are relations. The Uncertainty Principle is taking those universal properties of waves and applying it to matter and energy. It is not a result of imperfection in equipment or interaction of particles, is has to...

I think of it as a localized wave. Imagine the waves in a pool combining in such a way that there is a big bump in the middle of the pool that smooths out to the boundaries of the pool. A bump, that is a localized standing wave. Pool waves never do this, because the wavenumbers are pretty...

Well, the Schrodinger Equation is not Lorentz invariant. While your question seems simple enough, I don't believe there is a consensus on how to correctly do it.

Well, in QM, the particle can have less energy then the potential barrier and still pass through it. Only the infinite well DOES NOT have barrier penetration. Thats one thing that makes QM non-classical. Albeit, the lower the energy of the particle, the less chance for penetration.

It may seem obvious now, but why in the World would one choose a "pilot" wave to represent a particle? I sense a Bohmian. :smile: I would argue that Max Planck, recognized by the Nobel Prize Organization as the father of QM, is the father of QM. :rolleyes: He was the first to...
