Yes. DrP is right: "quantum" means "discrete;" the alternative to quantum is continuum. My favorite Vizziniesque word/phrase (it doesn't mean what the user thinks it means), though, is "space age," as in "space age technology," which is still being bandied about. All that really means is that it's been around since the late 1950's, i.e. 50-60 year-old technology is still space-age. Eight track tapes are space-age technology.

I assume you've placated the margin lady

I wasn't saying that they are one and the same, just that opinions are within the set of subjective and internalized statements. And I was assuming that this is in the context of arguing in good faith, which excludes the possibility of lying. (Locally that is called trolling, and that's a no-no)

I refer you to the answer previously given by Atheist:

Yes, that's basically it, though I wouldn't say it's a new signal – it's the old signal but at a higher amplitude. Here's another wikipedia link http://en.wikipedia.org/wiki/Optical_amplifier We're using erbium-doped fiber amplifiers in our lab. You can frequency-double 1560 nm light and that gets you 780nm, which is where the D2 line of Rb is.

I agree with what Moo said, and I'll add this: I don't think you have to support your opinion. If it's truly an opinion, that is. We are all irrational, to some extent, and hold irrational beliefs. And some things are actually subjective. One of my big concerns is differentiating opinion from the assertion masquerading as opinion. I think this can be a difficult thing, and posters need to get get into the habit of clarifying their statements, because this can be a source of friction and confusion, when people interpret a statement in different ways. I think this is a true statement: opinions are internalized and subjective. I like vanilla. I think Carrot-top is funny. (to be clear, I don't necessarily hold these opinions — these are examples). Likes/dislikes, and funny/unfunny are subjective. Assertions are external and objective — something that can be verified or not. If the statement is objective, then you cannot hold an opinion about it — I can't think of an example where this doesn't hold, but it's early and I haven't been properly caffeinated.

I don't see the value in linking to another bulletin board where they all agree that your proposal is rubbish. Can we observe these "magnetic holes" now, before the LHC is turned on? Why haven't physicists observed them already?

If you are asked, "Is that a watermelon in your pocket, or are you just glad to see me?" for more than 4 hours straight, see a doctor.

This commentary is inappropriate

Is there a question here? You can define mass this way. Or you can use the rest/invariant mass. The equations you construct will be different, based on which definition you use. Which is why you must define which mass you are using; you did not do this in your original post. The default for "mass" is the rest mass, in most physics discussions.

I think the request was for support that aircraft design uses relativity in any way. There are a lot of models that use an "effective mass" (or similar terminology) because it makes the modeling easier, but that does not really seem to be this issue here. In SR, [math]E^2 = p^2c^2 + m^2c^4[/math] where m is the rest/invariant mass. One might choose to define mass as [math]m = \frac{E}{c^2}[/math], but that's not the same thing, as it is frame dependent — these equations will only give the same answer in the rest frame.

What science really hates are claims made without substantiation. If evidence is ambiguous, you do a different experiment to solve the problem. That removes the alternative point of view. Outrageous claims like yours are most easily explained by you being unaware of the massive amount of evidence already in existence. What we need to see from you is evidence. If you do not supply any, the thread will be closed

It has the same wavelength because the energy difference of the states dictates this. If it wasn't in phase, the states would be interfering, meaning less energy, and that violates conservation of energy.

No, it depends on the number of protons, because that directly affects the electrostatic interaction. To a much lesser extent it will depend on the number of neutrons, because that affects the charge distribution in the nucleus. (all of this without getting into QM)

A concept for Chuck Norris to understand is that even though the forces are equal in magnitude, they act on different objects. A force acts on you, and you accelerate. The reaction force acts on the other object, and it accelerates.

Could you please rephrase the objection? There's nothing wrong with what baxtonduglonn said.

Right. A probe of some sort is not going to know if the source of the field is a permanent magnet or a current in a wire — a moving charge is going to behave in accordance with F = qv X B. You might be able to deduce the source by looking at the whole "map" of the field.

It's not a physical mechanism. It's a consequence of the speed of light being constant. Merged post follows: Consecutive posts merged It doesn't? I can perceive and measure three spatial dimensions and a time dimension. As far as I'm concerned, they exist. (I'm not going to get into a discussion of what "exist" means.) I mean the length contracts, just as I mean time dilates. Items used to measure those dimensions will behave accordingly. The distance between two coordinate points (be it time or distance) will depend on the reference frame you are in.

Not all clocks are based on classical movement, though movement is a convenient way of building a clock.

What was ridiculous about my answer? My suggestion was not meant to humiliate you. Relativistic thermodynamics is still sort of an open area of physics. http://www.aip.org/pnu/2007/split/843-1.html Hoping to have an understanding of it without a good background in thermodynamics and statistical mechanics is going to be problematic. There are many different thermodynamic potentials, each applying to different situations. The problem here is that the statement of conservation of energy doesn't account for all of the energy terms. I don't know what happens to entropy in the new frame, but I'm not convinced that it would be the same, so the Gibbs Free Energy is probably the term you should be looking at here. G = U + pV - TS If you're intimidated by all of this, consider not blaming the messenger.

No, it's more like you've hit the conceptual speed-bump that trips up many beginning physics students. Think about ajb's post very carefully.

Laser pointers are cheap, but you can do it with even less sophisticated sources.

I think it would be helpful for you to take a course in thermodynamics and learn about thermodynamic potentials.

As insane_alien points out, this will tend to slow us down, which would add to the moon's tidal effect. Weather patterns and mass distributions affect the rotation rate, and since they are unpredictable over anything but an extremely short time, they are monitored — GPS doesn't work so well if you don't know where the satellites are with respect to the earth.

Weird Theory, posting "alternative" science outside of the speculations forum, and in response to a science question are both contrary to the rules you agreed to follow when you joined. Please review them and refrain from such behavior.

Yes. It follows the same laws of physics. The details of the field geometry will be the only possible variable, but in any case it will comply with Maxwell's equations.
