Universal physics reddit
- Universal physics reddit. But why i can't understand physics, there is no point of return that means my 3 years of high school still need to study physics, how can i understand physics better with my higher level math concept? i don't need to get a high score on physics, just pass is enough, because i don't interested on physics, i interested on accounting and Pure Even the majesty of the metric system doesn't help; Celsius, for example, has 0 as water's freezing point and 100 as the boiling point. Physics. Even the majesty of the metric system doesn't help; Celsius, for example, has 0 as water's freezing point and 100 as the boiling point. By the time we send astronauts to Mars, physics would have played a part in practically every aspect of the modern world. The most famous are the postulates of quantum theory. So what your question really comes down to is the following: "Does a universial set of laws of physics exist?" where "universal" means that we can use them to deduce the behavior of any system that can exist in nature, anywhere. It was intended as an introduction for people without a strong physics background and I think it does a very good job of explaining things at a high level without completely dropping the physics. You might choose the CMB rest frame as your "universal reference frame", for instance. EDIT: universal -> fundamental to avoid causing more confusion than is already present in this thread. As modern technology evolves the physics behind it does too. Khan academy also has physics topics that cover physics at the high school level. So that’s something to bear in mind. The problem with what you asked is that physics is vast. ) Are the supermassive black holes at the center of every galaxy the same as the nuclei in every cell? A nucleus is essentially a cell's "hard drive" – it houses/protects the DNA, which contains the information the cells needs to make proteins. It really is an amazing subject. The point I'm making is that physicists don't really use the term 'law' in any way distinct from the term theory. There is no universal radius dilation experienced for the signal moving along “r=t=0", and there is maximum universal radius dilation experienced where “r=L0" and “t=L0/c". However, we recognize that many people want to discuss how they feel the research relates to their own personal lives, so to give people a space to do that, personal anecdotes are allowed as responses to this comment. If you consider the laws of physics to be, what can be demonstrated to be true, this might change along with the state of the universe at the extremes of the timeline of its life, for example at the instant of the big bang the physics could be so different to what can be demonstrated now, then you could say the laws have changed over time. Universal Fighting Engine 2 (PRO) : Universal Fighting Engine (UFE 2) is a set of tools and framework to help develop 2D, 2. In this context, “real” means that objects have definite properties Sep 21, 2016 路 Quantum physics is our basic theory of how particles and the forces that act on them work. For now I’m not interested in a specific physics field, but I’m a bit intrigued by medical physics( basically I like the idea of apply mathematics and physics to radiotherapy , imaging etc. UnityAssets is for sharing Unity Engine Assets! Just post a link to your asset and flair your post with… 92 votes, 110 comments. Universal Pathways allows you to jumpstart your path to higher education through Universal Learner Courses (ULCs) - an affordable, low-risk way to earn college credit at your own pace. The transition for electrons in a hydrogen atom is the same here on earth as is in galaxies as far away as we can observe. Depends what kind of multiverse theory. If you mean Everett then physics should be the same since the multiverse is generated from quantum branching, and I don’t think it incorporates some kind of evolution of physical laws so they should be the same. As shown by the example of torque, a moment can be directional. I’m 100% sure the laws of physics are universal, even if we don’t know or haven’t modeled those physics correctly. || APA guideline on how to cite us : [username] ([post date]) [Post title], Hypothetical Physics, Reddit, [url] Access date: [current date] members Being a universal common reference frame doesn’t make it absolute. See the rules before posting, and the subreddit wiki for common… Heads up: I'm a physicist. An example of a higher-order directional moment would be the moment of inertia, which is a tensor, or the second moment of area. The concept in physics is closely related. We would like to show you a description here but the site won’t allow us. I'm wondering if there are any laws of physics that could be used for units of measurement in all situations Only unitless constants (like the fine structure constant) contain any physics information. For physicists and physics students. || APA guideline on how to cite us : [username] ([post date]) [Post title], Hypothetical Physics, Reddit, [url] Access date: [current date] 14 votes, 13 comments. It only needs to follow patterns to make it look coherent to create an illusion that it is working 'for some reason'. Changes in the fine-structure constant (or "alpha") would show up as changes in the spectrum emitted by different elements or molecules, so scientists can measure atomic/molecular spectra in different parts of the sky using telescopes and compare. University physics is, in my opinion, more similar to A-level maths (especially the mechanics parts) than it is to A-level physics. I struggle with reading math books and use a lot of online resources, but for Physics I often find the books easier to follow and understand than straight up math, so definitely read the books thoroughly. e. 5D and 3D fighting games using a variety of easy-to-use Unity editors. Or at least, I was when I was in grad school. Besides that, a google search with "filetype:pdf" is indispensable at any level. I want to know if there exists a universal physics calculator as part of a general coding language. -GmM/r is only valid outside the sphere (the same as the potential of a point mass, see below shell theorem). Well, since Entropy and Time are intricately connected, my next thought was that instead of trying to imagine a black hole in all the ways and mathematical tricks we've come to learn to think about them and their environments, etc. The chaos that happens with turbulence is not due to an inderterministic nature like quantum mechanics, but due to the fact that even if two systems that have for 99. 99999999999 % the same initial conditions, it is still possible for them to have very different behaviors after a short time, because those differences blow up exponentially if the system is in a region of chaotic behavior. Any advice on how… All branches of physics rely on calculus some way, from thermodynamics to special relativity to quantum field theory, and although you might very occasionally get a problem set in college that doesn't involve any calculus, there isn't a single upper-division physics course that's integral-free. Ex. Unitful constants are just conversion factors, and their value just depends on how we've chosen to define our units. I'm wondering if there are any laws of physics that could be used for units of measurement in all situations He takes the reader through the history of particle physics - and in doing so, he brilliantly explains quantum physics, cosmology and touches on relativity, chemistry, string theory, supersymmetry, gravity, and other related fields. But for the last 100 years or so --- basically everything after relativity, we have just stopped calling things "laws" apart from a fe Both laypeople and physics scholars are welcomed here. We can observe a lot about the universe right now, and it's largely consistent with homogeneous physical laws. Remember, this sub is not an excuse to not do a Google search first. But we look out into space and see how many of those laws we can apply to other things, and so far it's most of them. Or check it out in the app stores Dreams, The 4th Wall, and the nature of universal physics and I don't know if this belongs here, but this article states 'Alpha', a constant in nature, varies in different areas of the universe. to sum it up, nearly 90% the classical physics is translated, and modern physics isn't usually. To add to this, beyond physics, a moment. 01 Lecture Series (Classical Mechanics) 8. true. but i don’t know the prospects of this path and I want to take at least one exam before chosing it) but, yes, I think that this is good idea. We really only know the laws of physics as they exist right here on earth. But it also describes every possible location of those particles at that instant. Effectively, this equation for length dilation behaves like a simple position equation. I love popular science and have read most of the better known books on physics. . UBI is more like Social Security. People’s experiences of first year can vary a lot depending on what school they came from and what university they go to. So what would be an absolute reference? A "universal common reference frame" is about as close to absolute as it gets. Oct 6, 2022 路 Quantum Physics. some exceptions to that 90% are thermodynamics, energy, and entropy. He wrote/voiced many books but the two with the heaviest science that relates directly to vortexal nature of interdimensional reality is "Infinite Concept of Cosmic Creation" and "Keys to the Universe and the Mind". There's really no single resource on all of Physics, and all the resources are fairly deep in their specific fields. But as far as I understand, while unlikely, it hasn't been ruled out. The "universal law of cause and effect" is a philosophical concept that has no basis in physics. 9G If you have at least some math and physics background I highly recommend Relativity: The Special and the General Theory written by Einstein. Hey ur me! no, but I also study physics in Sweden at Chalmers/GU and I'm in my 2nd year. I disagree, activity within the physics community has risen exponentially. I was thinking about the increase of entropy as a black hole 馃暢 is approached. I'm wondering if there are any laws of physics that could be used for units of measurement in all situations Both laypeople and physics scholars are welcomed here. The standard books we used for university physics are Sears and Zemansky University Physics with Modern Physics. , what if since entropy and time are "intimately" linked, one could think of a black Well closest I've found to the science that Walter Russell taught is from a person called Ernest Norman. Inside a uniform sphere the potential is proportional to r² (not 1/r, see here; the force pulling you to the core is linear ~r just like Hooke's law) and as you rightly is, coming from the sources and moving towards the core, decreasing. But sure, you can still call it relative. Received a 99. The laws of Physics are so complex, essentially they aren't the same anywhere else. Scientists have indeed looked for this, in particular with the fine-structure constant, which is important in atomic theory. Michael Van Biezen on YouTube has some great videos for calculus and physics. It is the foundation of the hugely successful standard model of particle physics – the most May 20, 2020 路 The universal wave function describes the position of every particle in the Universe at a particular moment in time. Tesla's 'theory' of gravity was about as fleshed out as Fermat's Last Theorem was fleshed out on the margin of a page of one of Fermat's books, yet the AI paints it as some legitimate alternative which was just cryptic (because of the genius of Tesla and our inability to understand the relativity-denying genius, obviously), after this framing the point that it 'lacked mathematical details Reddit has been pretty great with resources, as well as the Freenode IRC for #physics. This mostly stems from the James Webb Space Telescope's most groundbreaking study that the universe is expanding at different rates. One of the more unsettling discoveries in the past half a century is that the universe is not locally real. You basically repeat high school physics but the problems are harder and you may begin to derive some of the equations. Get the Reddit app Scan this QR code to download the app now. Walter Lewin (MIT ex-prof. Are there any guaranteed "universal truths" in physics? AFAIK as a physics student, all our current models mostly work, though only in the edge case that is our "near" neighborhood in the universe. Popular examples of systems of natural units include the Planck units, commonly used for topics like quantum gravity and string theory, and Hartree atomic units, commonly used for topics like atomic and molecular physics and chemistry. 7M subscribers in the Physics community. ) via Youtube: 8. 5% in Physics 1, with the average grade of the 150 students taking it that semester being a D+. Both laypeople and physics scholars are welcomed here. Though who says, for example, that gravity doesn't become a stronger force than EM in some extremely remote part of the universe? The way I see it, mathematics is a human construct but physics is universal. 02 Lecture Series (Electricity and Magnetism) Exactly, everybody is missing the "universal" part of this. Not by a large margin, mind you, but by a slight detectable amount. We don't really know why our universal physics work, we just operate with it as a fact of matter. Physics for Scientists and Engineers by Tipler and Mosca. The biggest additions to the toolkit on version 2 is the native netcode with deterministic physics (des Some folks have remarked on math axioms, but physics has "postulates" from which a theory is derived. Oct 23, 2021 路 Physics -- Textbooks, Physics -- Problems, exercises, etc, Physics Publisher [Place of publication not identified] : Addison-Wesley Collection internetarchivebooks; printdisabled Contributor Internet Archive Language English Item Size 3. Even in classical mechanics what you see is systems evolving in time. god looking at me looking at someone in a truck throw a ball vs the person in the truck His playlist pretty much covers it all. The equation of state isn’t enough to know what the final state looks like. || APA guideline on how to cite us : [username] ([post date]) [Post title], Hypothetical Physics, Reddit, [url] Access date: [current date] I’m 100% sure the sun will rise tomorrow. Source: Just hired as a paid physics tutor, though I've been tutoring students in my spare time for months. Also, "laws of the universe" are just equations derived from models that are ultimately simply descriptive of experiments. Oh God, I just made that my new major, and looking at overviews for courses I'm going to take next semester, it's like 'Oh yeah, it's just CHONS, well except for hemoglobin that has iron in it, and also do you like figuring out the exactly point on this 2000 amino protein some dipshit polymerase forgot to put an adenine and now the whole thing is fucked and for some reason conforms into the Unlike us AI doesn't need to 'know' physics to make it work. The only way I'm able to make sense of Einstein's theory of relativity is its all about perception , but if we picked a universal reference point that was independent of both observers i. Does Quantum Theory really rule-out universal determinism? The (apparent) randomness of the quantum world is well-documented: Heisenberg's uncertainty principle, the double-slit experiment, quantum entanglement, etc. Relativity is a 23K subscribers in the UnityAssets community. (I'm not sure what measuring something "with respect to space" is supposed to mean though. I am looking into systems of natural units, physical units of measurement based only on universal physical constants. I have a nice standard physical Casio-FX991ESPLUS calculator which has numerous calculators but it can be problematic to use that small screen. Please read all of the rules before posting. all point to a probabilistic universe as opposed to a deterministic one. Because the DNA is so important the cell is very fussy about what can go in and out of the nucleus, so it's continually transmitting parti Hope this helps, and I hope you have a great time in intro physics. I hope Einstein will forgive me for my blasphemy. Study conceptual physics online free by downloading OpenStax's University Physics Volume 1 textbook and using our accompanying online resources. Also, you can check lectures by Prof. If the sun doesn’t rise tomorrow, it will be from a natural phenomenon that could happen anywhere in the universe under the same conditions and for the same reasons. I think UBI is probably a good idea, but the way I would envision it is as a way to massively cut down on fraud, abuse, required oversight, and thousands of crazy other rules and programs. You also need to know what kind of process the gas is undergoing. Now I'm certainly no expert but I just can't understand the logic behind light being the same in all reference frames. Some find it easier some find it a lot harder. Water would boil and freeze at different atmospheric pressures, though, so even that isn't universal. What we have discovered is that our understanding of the laws of physics is incomplete. notice that the names of scientists in physics things like Ampere (I), Fahrenheit (F), Tesla (T), Newton (F), and others obviously are not translated. I struggled really hard the first year too, failed my first exam, felt stupid in my first group assignment & felt like everyone was wayyyy smarter than me. Let us discover together the possibilities of our multiverse. Getting to the introductory college level, you will need single-variable calculus at least and pre-calculus. I think there are models that purport to explain dark matter or dark energy by challenging this assumption, but I don't think they're especially mainstream or well-developed at this point. Other species could have found different ways of describing such phenomena but the phenomena they are trying to describe is the same. Is this true… Welcome to r/science!This is a heavily moderated subreddit in order to keep the discussion on science. Intentions of getting me NMLS licensed and to study the ins and outs of all the things related to our bank. ) However, there is no special or privileged inertial reference frame — in other words, physics works the same in all inertial reference frames. Everybody partakes in it, rich and poor. It is at best irrelevant and at worst nothing but wishful thinking. No HW, no career questions in top post. The following programs let you take first and second year ASU courses for college credit. 2. || APA guideline on how to cite us : [username] ([post date]) [Post title], Hypothetical Physics, Reddit, [url] Access date: [current date] Aug 11, 2022 路 Using the mathematical tools that describe relativistic phenomena in physics, the theory shows that if the dynamics of Bob’s neural activity could be changed to be like the dynamics of Alice’s neural activity, then both will be in the same cognitive frame of reference and would have the exact same conscious experience as the other. skkhzy dhwk poypp osgk rfjfuf gvwn ewrmvg piftlks arp hpg
