Human physiology isn't a matter of how a particular atom is spin-polarized.

And when researching special relativity and quantum mechanics, you can leave logic far, far behind.

TIR only happens for light entering a medium of lower index, so it will never happen for light going from air to glass. It will occur if light tries to exit glass at certain angles, which is how multimode optical fiber works.

Use whatever, just not text-message shorthand. I find that quite annoying and have a hard time believing that anyone is typing posts on their phone keypad.

The atoms aren't being teleported. Data encoded in them is. So "this" technology is never going to advance to that point. The reason this is being done isn't to make a Star Trek transporter. It's because classically the fidelity is 0.5 - i.e. you lose half of the information about the states. Using quantum entanglement you can theoretically achieve 100% fidelity. Experiments have shown >0.5, demonstrating that the classical limit has been beaten.

True for me as well. Generally the only people I correct are people who should know better and address me as "Mr." anyway, rather than by my first name (I mean, if you're going to get formal on me all of the sudden, you might at least get it right) I also find that people who have degrees that they didn't really earn (honorary or purchased at a diploma mill or unaccredited school) are more likely to insist on being called "doctor." The people who are impressed by your title alone are invariably the ones you don't want to waste time impressing. People you'd like to impress aren't going to be impressed just by the title.

There is no radial force. It's an illusion because you are in a rotating reference frame when you look at it from the wire or bead's point of view. The force is always tangential in an inertial frame.

If there was any sulfuric acid in the water it would tend to turn yellow when the acid decomposed.

~10 keV X-rays aren't going to eject neutrons from Al. The energy required to eject a neutron from Al-27 is about 13 MeV. You are probably thinking of alpha scattering experiments. edit: used "alpha" instead of the tex. It worked in preview mode, though...

Specifically' date=' raise the current. If you raise the voltage you will get higher energy in the continuum but not in any transition-specific values. If you want more intensity you need more electrons. [sub']edit: spelling[/sub]

I tend to agree - I don't have much use for the willfully ignorant.

I'm not sure what you mean by 50% density.

Photon momentum is E/c. The have no rest mass.

Your question depends on what you are trying to shield - there's the current of the lightning stroke, and the EM radiation that it gives off. You can obviously be protected from the current by a properly grounded lightning rod. In that sense the lightning is basically a DC signal as far as understanding the dynamics. But the short duration of the stroke and the acceleration of the charges means that EM radiation will be given off. You car isn't going to protect you against that, since radio waves obviously can penetrate inside.

Under what assumptions? Do you have a link for this?

[math]1/r^2[/math] is from a classical gravity equation. Electron size is quantum mechanics. Danger, danger, Will Robinson!

If you move the source away from the observer it will redshift. Also there are crystals in which you can do nonlinear optics and get frequency doubling (the direction it's usually done) but you can also get difference frequencies, and go to lower values. So yes, it's possible.

Dirac theory has the electron as a point particle; no structure. Every experiment of which I am aware that measures the size is consistent with zero. You can't state that a dimensionless particle will create a singularity until you have come up with a theory of quantum gravity.
