>>767595471 It all started when I was an impressionable highschool student. I thought all the cool kids would be experimenting with physics. Sadly my addiction got worse and worse and rehab didn't seem possible.
>>767595519 Probably because i'm kind of short sighted. I really do like math but I can't get into stuff with 0 application. I could have done applied math but that just seems no fun to me. >>767595563 Good question, I have to experiment more to find the answer. The band? Not much. I'm like a super hipster black metal kind of guy
>>767595366 where the fuck did you get a job.. how were the interviews?
>kk mr anon, here at HAL laboratories we need an extra scientist to research carbon nano tubes, what are your qualifications? >well you see mister faggot-san, i learned allo i know from NOVA and vsauce videos, >holy shit come right in...
>>767595366 > this shit show again from a retard that isn't an experimental physicist but thinks he can impress people with a title > so desperate for accolades over his made up title even needs to seek anonymous praise kys faggot
>>767595688 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" >>767595726 I think you can just use the vector triple product: a\dot(b x c) >>767595731 I did my masters degree, and was taken on as a contractor for a university because of my research experience >>767595756 I am the bbcnt >>767595758 No idea fam >>767595762 Yea I kinda do. I'm a bass player so I really respect Justin >>767595831 Tell me how I can prove it, or show me how you're better then me on this anonymous israeli wicker basket forum >>767595889 My main project is on building an all inclusive broadband cavity perturbation setup for determining unknown dielectrics. >>767595909 To stroke my ego, but i'm not lying about this
>>767596181 If you mean the band not really >>767596132 The measuring is the key part. To measure something is to perturb it and changes its state. >>767596203 What do you mean? What singularity? >>767596282 You need to find a way to cancel the strong and weak force, not the electromagnetic force. The best suggestion would be to stand in front of a particle accelerator for a while
>>767596513 In which universe? My waifu is Reki from HnA, but man that series is an awful shitshow. There are plenty of very good girls tho. >>767596548 Phis isn't bad by any standard it's just not my go to music. For jam heavy stuff I listen to a lot of post rock. I just like stuff that's a bit more aggressive, or on the other end of the spectrum like japanese lounge jazz. >>767596608 It's just a neat math thing, and I haven't seen it in what I work with >>767596627 define singularity. That's a really vague term
>>767596669 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. >>767596674 In some interpretations of the universe sure, I don't buy that though
>>767596796 I buy into whatever we can experimentally validate. I'm very much in the field of "shut up and calculate". If we prove alternate universes or extra dimensions sweet, but until then I'll just not think about that crap >>767596866 I appendix carry mine
>>767596991 I don't do high energy so I don't really know. I do condensed matter. I don't think about that shit very much. I have friends doing high energy theory and it seems fun but I couldn't take it seriously. >>767597065 Those don't exist, but if one did and the universe wasn't fucked sure you should be able to shoot shit into it I guess. >>767596992 What kind of moment do you mean? That term can be either simple or pretty darn complex if you're doing theoretical mechanics
>>767597368 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. I really like supersymmetric theories for simplicity and "beauty" but most of those keep getting pushed further and further back. I think that there is no clear consensus as to how or why we exist. >>767597404 It pays the bills.
>>767597494 No idea, never took GR or cosmology >>767597509 I think it has no experimental validation >>767597533 Can you give me an example of what moment you're talking about here? A lot of it would just be read whatever mechanics/statistic book you are using and get used to the formalism of it. The secret to getting good at physics is just doing more and more problems until you see patterns
>>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.
>>767597715 I wouldn't really classify myself as either, but I never think about metaphysics or the philosophy of science too much >>767597865 I'd say it's quantum computing. That shit is going nowhere but god people love throwing money at it >>767597878 Yea that's what I said earlier. My first response was to use the triple vector product, which is the dot of one vector and the cross of the other two
>>767597997 if you could find the index of refraction of mayo you could figure it out, i'm not sure >>767598094 probably not, could be due to a lot of social things though. You're not looking hard enough, need to take better care of yourself, need to find better people, etc
>>767597639 >A lot of it would just be read whatever mechanics/statistic book you are using and get used to the formalism of it. The secret to getting good at physics is just doing more and more problems until you see patterns
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.
>>767596346 Confirmed that you are not a physicist. Balance the strong and weak forces to eliminate EM forces? The scales and binding energies are so completely different that that comment is beyond autistic and irrelevant.
>>767598743 Just because I do experiment to pay the bills doesn't mean I can't do theory. If I could get an easy job working with 2D+1 Chern-Simmons topological theories with focus on non-abelian anyon braids I would. I just like playing with expensive toys. >>767598760 It's because it's wings don't do a standard "up down" motion, they move in a figure 8 pattern >>767598841 generic mixed white. I think it's irish and french >>767598896 You said you wanted to break apart atoms. EM isn't what holds the gluons together. >>767598925 Probably
>>767598760 >, and so I guess you don't believe in proper syntax either. >>767595366 are stem girls family oriented? the few Ive met seem to want to wait until theyre older and the others basically quit their career to be a mother, i dont see any part time physicists.
>>767599140 The people I see at the university I work at seem to be a mixed bag. I know a few fresh grad students who already have kids and are married, but normally it's to someone else in the department or another physicist somewhere. >>767599192 Could be a lot of reasons, probably do to socioeconomic factors and self-fulfilling prophecies
>>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 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.
>>767599267 >The people I see at the university I work at seem to be a mixed bag. I know a few fresh grad students who already have kids and are married, but normally it's to someone else in the department or another physicist somewhere. 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 What do you want me to explain? And trust me that's not specific to experimentalists. The amount of theory professors I had that refused to teach anything outside of what they do was frustrating as fuck. Tell me what i've said incorrectly and what you want me to prove better >>767599447 As far as I can tell not really no. If you're capable and can prove your shit you can do the cool stuff.
>>767599585 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). This is the type of basic shit you have to know to answer questions at a phd level.
>>767599721 he might have, but probably not on a regular basis. >>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)
>>767600004 Again, I know that zero point energy is a real thing , just look at any introduction to second quantization and you'll see that. I'm saying that if you're lumping together telepathy and the phrase zero point energy you probably have no idea what's being talked about.
>>767595366 Experimental means shit. If I throw a ball down a flight of stairs and record it's time traveled to hit the bottom I'm technically an experimental physicist. Now if I theorize what might happen before hand using math and shit, then is need credentials. Tldr op had a bullshit title, to justify a degree. It's like welding engineers.
>>767599922 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.
>>767600097 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
>>767600429 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)
>>767600370 I explore physical properties using experimental techniques and develop new equipment to probe undetected or new physics. >>767600328 I guess you got me >>767600445 Yea that's true, but why take out anger on someone else over something so trivial? Why waste time on this forum if you think i'm full of shit. If I'm that useless and beneath you why even dignify me with a response? >>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. >>767600655 Honestly I'm not sure. An associates doesn't seem like much to me
>>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. >>767602577 I don't think they have much impact on our day to day lives >>767602690 None luckily.
>>767603487 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.
>>767603581 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?
>>767604133 My bet would be on how big the universe is, but I don't have a hat in the ring in any sense. >>767604295 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.
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.
>>767605242 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. >>767605199 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.
