Kind of, but it's nothing special. In QM we consider literally any interaction to be an "obvservation". It's not some mystical "human consciousness changes the particle man" but more of a "literally anything we do will send some other particle to interact with the system, so we change its properties"

The cross product just produces a vector perpendicular to the others, not a volume. That's why I think the answer is the triple vector product.

In my uneducated opinion, I think string theory is on to something but needs to find some way to get discovered at reasonable energy scales to even start to matter.

>>767596731
Cross product gives a vector with magnitude equal to the area of the parallelogram formed by those two vectors. Then you need the magnitude of the component of the third vector that is perpendicular to your other two vectors (dot product). Luckily, you already have one vector that's perpendicular to them, because you just found the cross product. So take a dot product of the cross product and the third vector, multiply the magnitude of the cross product by the dot product, and you have your prism's volume.

Will just do this.

My problem is I have to translate everything from English and then try and understand it or use my shitty languages very incomplete books to try and comprehend it. When I calculate moments it always kicks my ass so its clear I am missing something but will follow the practice makes perfect thing.

>>767597065
Singularity in actual physics refers to a breakdown of the equations, which can lead to infinite predictions (no necessarily mass, which is never infinite in formal calculations). For instance, curvature or density of energy can blow up in general relativity. But sure you can shoot particles at a singularity to expand it. That's what happens with black holes--the particles reach a singularity and the black hole radius expands proportional to the square root of the total mass. However, this is what's called a "removable" or coordinate-dependend singularity (the "event horizon"). The "infinite curvature" singularity is singular in GR, where extra energy doesn't expand it but instead de-stabilizes the singularity (this is what probably happens in actual BHs, so there is no infinite density point when adding matter effects). There's antigravity ways to stop the singularity, in that antigravity balances gravity so the equations no longer blow up at a point, and I think this is more or less what you're getting at (wormholes, etc)
>>
>>767595366
Gauss, Euler, Newton or Cauchy?
>>
>>767595366
Why are you pretending you can answer questions about physics when you're an experimental physicist (who sounds like a fresh graduate student)? Your knowledge of physics is rudimentary and almost worthless for anything outside of your nuances research topic (which is why experimentalists usually aren't even asked to teach something as basic as intro grad courses). Waste of time board.

ah yeah that makes. follow up. at your level do cliques/politics come into play in terms of who gets recognized for work/ opportunities to take on something cool?
>>
>>767599315
That's a tough one. I want to say Newton since he started a lot of shit (yea yea leibniz was doing his thing but w/e) but Cauchy managed to stick is name in like every important theorem ever. Gauss also did some fantastic general stuff, and Euler was crucial in any sort of modern wave analysis, so I can't pick one. I might just say fourier because of how fucking powerful the fourier transform is though.
>>767599408

Well it's pretty obvious you have no idea what a singularity is, failing to identify them in black holes, in quasiparticle solutions in condensed matter systems, in potential topologically stable states in the early universe (domain walls etc).

>>767599760
It's really hard to seperate the bullshit memes from actual competent questions. I don't expect most people here to know what they are in terms of trivial/removable singularties and in actual cases of things like GR or astroparticle. I assume most people are thinking things like "infinite energy monopoles man". Before I start talking about something I want to make sure i'm answering the right question.
>>
>>767599692
Zero point energy, another name for physical vacuum energy manifestations like the Casimir Effect and its relativistically retarded brother, vanderwaals interactions. It's not just a meme but an important driver of interesting nanophysics such as frictionless gears (that take advantage of the geometrical dependence of the casimir effect in a situation where it leads to not dissipation)

Singularities, monopoles, and zero point energy aren't very complicated things, and lots of people have heard of them. If you can't say anything interesting about any of those based on the questions asked, it really seems more like you don't know more than anything. But that's okay, 90% of the physicists don't know physics anyway so I guess it's fine.

Did I ever say anything about telepathy? Nope. But I can speculate on anything I want because I know the underpinning theory. More importantly, I could dispel telepathy while pointing someone in the direction of actual interesting physics. That's what understanding should be requisite to start a post of the ama type.

Also, your mention of "dur intro to 2nd quantization" pretty much establishes to me that you're either a 2nd year grad student or someone who doesn't know the theory outside of your specific research. That's such an overly technical, non-informative, wiki-way to talk about it that I've never heard it outside of self proclaimed intellectuals. You have yet to communicate a depth of understanding for anything beyond the first 3 sentences of wikipedia. keep trying though, im out

If you could cum out something similar to monopoles, in theory, their local energy density could change the local topology of your region of space, changing the eventual fate of your surrounding spatial universe. There was a vague paper about this type of thing (they never said the word cum but I'm sure they meant it) in '92, but is ruled out for boring things like canonical monopoles (but not cum monopoles so keep trying op)

>>767600614
I didn't say you did, but the person who first brought up zero point energy did in terms of asking how telepathy works. I never tried to say I was a genius or any of that shit. I mentioned my field is not in theory or HE or AP, and yea I don't know those very well. But seeing as how you do understand these things I think mentioning zero point energy in terms of introductory QFT is perfectly valid. I could bring it up the same ways you did but you would probably say that's intro drivel as well. Solving the QHE gives it to you, it shows up all over the place. I'm not trying to look like some badass, and I admit that theorists are smarter than me, in the sense that they spend more time doing the math and working on that part of it. But I don't understand how you can get past the PhD level and still have this petty "only X is the best everyone else is retarded" mentality. Experimental work isn't hard in the way theory is, but it's hard in ways theory isn't. Each branch is important if we every want to get shit done. Without experiment theory is just math, and without theory experiment is just engineering.

How does electricity work?

>>767602505
This is a good and pretty damn complicated question. Where electrons come from in general requires something called quantum field theory, but understanding where they come from in terms of electricity is a bit easier to think about. For most electrical systems, there is something called a ground, that (as the name implies) grounds the system to the earth. The earth is fucking massive, and has a lot of electrons to spare should the need arise. The common analogy is to think of voltage as a slide, where the electrons want to slide down from a high potential to a low potential. If I apply a voltage across a wire, I can detect a current flow, and a resistance, because I am "pushing" the electrons from one side to the other.

That's normally with 1 photon exiting 1 electron at a time, though.
I'm talking about trying to break off all the electrons on the plasmon at once. Not sure if it'd have the same mechanism.

Experimental physicists are just people who're smart enough to make the rest of is look bad, but not smart enough to be wizards.

I don't remember much about my studies with SPP's much, but I think Ibach and Lueth had a decent section it. I assume if you over energize it since it's a collective oscillation it would just scatter and become decoherent, kind of like excition decoherence in FWM, but I don't remember much

Do you think the absence of extraterrestrial "intelligent" life is due to the nature of evolution favoring "greedy" lifeforms and thereby causing their extinction before creating deep space travel, or is it because of the vastness of the Universe, or something else?

Makes sense, I figured as much.
Well, not to that level of thinking, but yeah.

My bet would be on how big the universe is, but I don't have a hat in the ring in any sense.

I assume you could just write down the dispersion relation for a surface plasmon polarition, and play with some perturbation theory to find out what should happen to the state.

Is there a solution to the paradox:

The statement below is true.
The statement above is false.
>>
>>767604503
Not that I can think of at the moment.
>>
>>767604409
Gotcha.
Thanks anon
>>
>>767604503
The statement above is false and the statement below is true. There.
>>
>>767604503
Yes there is a solution.
Both sentences taken together is true.
>>
>>767604817
Does that mean I should do the second statement ?

Why do physicists continue to claim time slows down when you approach the speed of light as seen from a viewers FoR when both people would be viewing the same thing, and the only reason it appears as though time slows down is because the time it take light to traverse the distance grows continually. And that if you returned to the viewer both would be the same age because the expanded time turns around to compressed time on the return trip.

Could the broadband cavity perturbation your working on be used in an early version of a medical tricorder ?
>>

Probably not, since it doesn't have much use in directo biomedical application. It's primary goal is in determining the dielectric function of new semiconducting materials. If you want something like that, I would look into CNT based biomedical sensors.

Time dilation falls out nicely if you start with Galilean transformations and move towards lorentz transformations. It's also an experimentally validated thing. Look at any work done with atomic clocks or even how GPS works.
