comment Is there any thing other than time that “triggers” a radioactive atom to decay?
Thanks, Helder. It's too bad that this website doesn't promote more discussion. I feel like after the first day or two, the topics just disappear from the radar.

comment How does scattering work?
I find it disturbing that people are upvoting this answer. Surely the scattering of sunlight by molecules in the air has nothing to do with coulomb potentials. And there is no attempt to address the question of why the sky is blue.

comment Tidal force on far side
Yes, the electrostatic case is the same as gravity. The immobility condition however is problematic. An important aspect of the tidal system is that the earth and moon are in free-fall about each other. That's why the average field has no visible effect, and only the distortional component is at work. Also, I question Nick's asymmetry. In my analysis, the quadrupole force is symmetric.

comment Angular Momentum of Diatomic Molecules
Yes, that's the same bond length I'm using; I've expressed it as 2.2 Bohr radii, using a value of 53 picometers.

comment Does a wing in a potential flow have lift?
Mike, you have posted the link to the only website anyone should ever consult when it comes to airfoils and lift. Well done. It's amazing that you got downvoted. I will refrain from upvoting your answer because I want the record to show the quality of voting that goes on here.

comment Wave/particle duality
I really posted my link because it specifically addressed your point about the photographic film. I wonder why it is necessary for you to bring up the photoelectric effect to counter my reasoning? My article deals with the photographic plate, not the photoelectric effect.

comment Wave/particle duality
I'm going to challenge the suggestionn that absorption of light works by the interaction of single photons with single molecules. In my blog article on Quantum Siphoning, I show how you can understand the process as the interaction of a classical e-m wave with an ensemble of atoms in the photosensitive crystal. You can read the article here: marty-green.blogspot.ca/2010/03/quantum-siphoning.html

comment Distinguishing identical particles
Nicely done, Pedro. I can't believe how much nonsense other people are posting in response to this very straightforward question.

comment Quantum Mechanics- Antenna emitting electromagnetic radiation
Vladimir, I'm quite sure that's not the intention of the question. There's no such thing as the minimum or maximum power of an antenna. The power received is always proportional to the incident power. I'm quite sure the person who designed the question chose a very small power in a misguided attempt to demonstrate that quantum effects can be demonstrated in a classical situation. In fact, even if we accept the numbers given, there is no way to detect the supposed granularity of the received power by measuring the antenna current.

comment Quantum Mechanics- Antenna emitting electromagnetic radiation
Technically yes, but again, it's not a physically realistic problem. A real antenna receives more power depending on what the transmitter puts out, but in this problem it only says the antenna is "capable" or receiving so and so many watts, without regard to the transmitted power. That's not physically realistic.

comment Is it theoretically possible to reach 0 kelvin?
Ron, you haven't addressed my point about the measurement postulate. Isn't the act of measurement supposed to force the system into a definite eigenstate?
