Universal physics reddit. Now I'm certainly no expert but I just can't understand the logic behind light being the same in all reference frames. 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. If you have your heart set on doing a Physics degree, please apply for credit transfer as I suspect the OU will exempt you from all level 1 courses, and at least 30 points at level 2, meaning you would only need 180 credits to complete a physics degree. Physics (actually, all natural sciences) work that way: see something, modelize that something, check it works, wait until something happens that your model predicts wrongly, repeat. 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. No HW, no career questions in top post. I am a physics major currently in my second year. We just don't have an answer that goes beyond conjecture. My advisor gave me the dean of science and math email to ask cause she had no idea. Solve 100-250 Questions per chapter depending upon the size of the chapter. University Physics is a three-volume collection that meets the scope and sequence requirements for two- and three-semester calculus-based physics courses. Errorless Physics books are written and recommended by top professionals and toppers. You're confusing the "laws" of the Universe with some grand adjudicator determining what is and isn't possible. e. Jun 2, 2024 路 Errorless Physics PDF 2025 (NEET/JEE) Universal Errorless Physics Books is a leading publishing house, which specializes in competitive exam books in India for medical And Engineering exams. Is this true… Both laypeople and physics scholars are welcomed here. ) However, there is no special or privileged inertial reference frame — in other words, physics works the same in all inertial reference frames. I hope Einstein will forgive me for my blasphemy. 2. Remember, this sub is not an excuse to not do a Google search first. You basically repeat high school physics but the problems are harder and you may begin to derive some of the equations. You also need to know what kind of process the gas is undergoing. . Get app Get the Reddit app Get the Reddit app 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 Yeah, the tricky bit here is that usually a freshman level astrophysics course is gen-ed so it'll lack the rigor a major expects. The Copenhagen interpretation isn't any more "physics" than the MWI, or Bohmian mechanics, or any other interpretation. || APA guideline on how to cite us : [username] ([post date]) [Post title], Hypothetical Physics, Reddit, [url] Access date: [current date] I want to know if there exists a universal physics calculator as part of a general coding language. My recollection is a little fuzzy but the idea is that the universal wavefunction in MWI should generally be written in the basis that corresponds to the o I went to college for aerospace engineering, and then, after failing Physics 1, I was told to just drop STEM altogether. Unitful constants are just conversion factors, and their value just depends on how we've chosen to define our units. As for your last paragraph, you’ve stumbled onto what’s known as the preferred basis problem. Get app When we analyzed median salary in the physics discipline acoss for-profit, government/military, and academic employers, this is what we found for avg median salary: - Physics for-profit: $101k - Physics gov/military: $53k - Physics academic: $66k We surveyed 5k+ optics and photonics workers from 100 countries, so it's pretty comprehensive. UBI is more like Social Security. 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. notice that the names of scientists in physics things like Ampere (I), Fahrenheit (F), Tesla (T), Newton (F), and others obviously are not translated. In other words, they describe the Universe. || APA guideline on how to cite us : [username] ([post date]) [Post title], Hypothetical Physics, Reddit, [url] Access date: [current date] r/Physics • The 2023 Nobel Prize in Physics is awarded to Pierre Augostini, Ferenc Krausz and Anne L'Huillier for experimental methods that generate attosecond pulses of light for the study of electron dynamics in matter Posted by u/deathstar3548 - No votes and 2 comments I found University Physics to be a little spoonfeed-y and overly simplified. In order to argue against universal truth one must make a proposition. , what if since entropy and time are "intimately" linked, one could think of a black Only unitless constants (like the fine structure constant) contain any physics information. Please read all of the rules before posting. 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. When a particle interacts with one another, it doesn't have any sort of internal programming telling it how it should be have (A good way to think about that is the hidden variables theory in Quantum Mechanics, which is proved wrong by Bell's Inequality), it just acts. What we have discovered is that our understanding of the laws of physics is incomplete. 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. 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. Besides that, a google search with "filetype:pdf" is indispensable at any level. There are many similar texts and lots of editions, any of them will pretty much do for a beginner. 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. 5% in Physics 1, with the average grade of the 150 students taking it that semester being a D+. One of the most successful theories in physics to come out of the 20th century is Quantum Mechanics. Starting with the fundamental principles of modern physics, such as Einstein's Theory of Relativity, we learn Literally all of them. 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". My biggest issue with these classes was the lab took so much time that I had no time for any other classes. " Heck, time could even be an emergent phenomenon of the universe, rather than something fundamental, depending on what we learn while trying to solve quantum By no means a physicist, but I think it's probably important to note that we do not necessarily have equations "dedicated" to studying black holes. I had to withdraw the first time and it wasn’t much easier when I retook it, even though I had already been through 2/3 of it before. Volume 1 covers mechanics, sound, oscillations, and waves. I would recommend any of the standard beginner texts for university physics, Fundamentals of physics by Halliday, Resnick and Walker for instance. Good luck! /r/Statistics is going dark from June 12-14th as an act of protest against Reddit's treatment of 3rd party app developers. Edit: Lots of info I’m sorry, but either way good luck! I also agree with OP comment about starting to learn the material two weeks before, but I would start even earlier (like a month) and review all HS physics (Physics 1 AP reviews helped me). || APA guideline on how to cite us : [username] ([post date]) [Post title], Hypothetical Physics, Reddit, [url] Access date: [current date] Yeah, I've thought about this one a lot too, but I think one of the big problems is that most of these constants are irrational numbers. There's really no single resource on all of Physics, and all the resources are fairly deep in their specific fields. Read NCERT Line-by-Line of Each Chapter, even Physics and highlight the important stuff. ) via Youtube: 8. All about Quantum Information, Quantum Communication, Quantum Measurement, Quantum Metrology… Here's the part I struggle with, redirect the denser patches of this "Universe" (Keep in mind, this universal matter is a constant, passing through and wearing upon but not neccesarily impacting our matter) to the rear of the ship, acting much like the aero fins on the back of the semi truck to offer a bit of thrust and increase vehicle efficiency. It is at best irrelevant and at worst nothing but wishful thinking. Or check it out in the app stores Dreams, The 4th Wall, and the nature of universal physics and Being a universal common reference frame doesn’t make it absolute. Ask a science question, get a science answer. It describes everything going on in the sub-atomic world almost perfectly, but there is a catch. to sum it up, nearly 90% the classical physics is translated, and modern physics isn't usually. Effectively, this equation for length dilation behaves like a simple position equation. _This community will not grant access requests during the protest. We really only know the laws of physics as they exist right here on earth. 19M subscribers in the Futurology community. EDIT: universal -> fundamental to avoid causing more confusion than is already present in this thread. Physics for Scientists and Engineers by Tipler and Mosca. 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. UnityAssets is for sharing Unity Engine Assets! Just post a link to your asset and flair your post with… I was thinking about the increase of entropy as a black hole 馃暢 is approached. Newton's law of universal gravitation states that the gravitational force from one object to another is proportional to the opposite of the square of the distance 1/r^2 between the objects. Welcome to r/science!This is a heavily moderated subreddit in order to keep the discussion on science. The way I see it, mathematics is a human construct but physics is universal. Both college physics 1 and 2 use algebra and trig with college physics 1 requiring college algebra and trig or pre calc and college physics 2 just needs college physics 1. Also, you can check lectures by Prof. This mostly stems from the James Webb Space Telescope's most groundbreaking study that the universe is expanding at different rates. 01 Lecture Series (Classical Mechanics) 8. Fast forward to now where I have a degree in Astrophysics after completing 5 semesters in a row with a 4. This textbook emphasizes connections between between theory and application, making physics concepts interesting and accessible to students while maintaining the mathematical rigor 3. I’m 100% sure the laws of physics are universal, even if we don’t know or haven’t modeled those physics correctly. Physics IA Ideas: Quantum and Nuclear Physics. 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. See full list on thoughtco. Our universe has a universal speed limit, but i dont see why another universe with no absolute speed limit would not be possible, sure it would be different than ours with some parameters of the laws of physics tweked differently or some bigger changes but seems hard to prove that just because you dont have an absolute speed limit then no This theory proposes an integrative and comprehensive view that seeks to unify fundamental principles of physics, established scientific theories, and advanced concepts of computing to offer a unified explanation for the origin, evolution, and nature of the universe and life within it. some exceptions to that 90% are thermodynamics, energy, and entropy. 3M subscribers in the Physics community. 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. Flashcards are very useful, but the maths that it does include can be fiddly, so once again practice is key. But sure, you can still call it relative. Posted by u/LordSt4rki113r - 12 votes and 25 comments Hey ur me! no, but I also study physics in Sweden at Chalmers/GU and I'm in my 2nd year. A proposition is itself a claim of universal truth. (I'm not sure what measuring something "with respect to space" is supposed to mean though. On the other hand, RH would explain as much was needed very lucidly but wouldn't overstep and let the student figure some stuff out for themselves through questions. Producing green hydrogen isn't anything new - we did it in physics class in school. For instance, both my undergrad and grad schools teach that class with The Cosmic Perspective, which is a perfectly acceptable text for that level of course but is not deep enough for the average physics major to bother keeping on the shelf. Those laws work great, but are incomplete. Relativity is a There are physics modules which make a lot of use of the Open Science Labs, an OU development which provides lab-like experience from your home, this includes both simulated and remote controlled experiments - for example there are remote controlled pendulums to experiment with SHM, waves, and resonance; there are remote telescopes in tenerife that you can control from your PC, there are Oct 6, 2022 路 They equally split the 2022 Nobel Prize in Physics “for experiments with entangled photons, establishing the violation of Bell inequalities and pioneering quantum information science The standard books we used for university physics are Sears and Zemansky University Physics with Modern Physics. Determine the spacing between the planes in the atomic lattice of graphite, using the de Broglie Relationship Determine the work function of a given metal Physics IA Ideas: Engineering Physics It can be done. || APA guideline on how to cite us : [username] ([post date]) [Post title], Hypothetical Physics, Reddit, [url] Access date: [current date] Open menu Open navigation Go to Reddit Home. 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. It is the approach that led Albert Einstein to his theories of relativity. || APA guideline on how to cite us : [username] ([post date]) [Post title], Hypothetical Physics, Reddit, [url] Access date: [current date] University physics 2 requiring calc 2. com University Physics Volume 1. I don't know if this belongs here, but this article states 'Alpha', a constant in nature, varies in different areas of the universe. Semiconductor / electron transport physics barely existed back then, and now it's the biggest field. There are universal truths. It only needs to follow patterns to make it look coherent to create an illusion that it is working 'for some reason'. Everybody partakes in it, rich and poor. ScienceUncensored is a place for anyone to post any interesting science or technology related… There are not more hours in a week now than 50 years ago, but physics has expanded enormously. god looking at me looking at someone in a truck throw a ball vs the person in the truck Scientists have indeed looked for this, in particular with the fine-structure constant, which is important in atomic theory. Should observable repeated phenomena break our current "laws" of physics, then the laws would need revision. Please do not message asking to be added to the subreddit. Water would boil and freeze at different atmospheric pressures, though, so even that isn't universal. || APA guideline on how to cite us : [username] ([post date]) [Post title], Hypothetical Physics, Reddit, [url] Access date: [current date] I answer that, Universal truth is the assumption of any argument. Received a 99. 02 Lecture Series (Electricity and Magnetism) This semester (spring 2020) I took PHYS 206 with Kocharovsky. For physicists and physics students. I ended up passing physics 1 and dropping introductory physics 2. Both laypeople and physics scholars are welcomed here. r/Futurology has gone private in protest of Reddit's recent behavior and planned changes to the API… The laws of Physics are so complex, essentially they aren't the same anywhere else. We have equations based on our understanding of universal physics that can be directly applied to studying black holes (and everything else). Not by a large margin, mind you, but by a slight detectable amount. The problem with what you asked is that physics is vast. Physics 2 was the hardest class I’ve had to take. Vixra Review A (VRA) presents significant scientific and philosophical developments whilst remaining… Physics underlies many of the basic functions of heating, lighting, transportation, even cooking! Understanding basic physics will help you with using energy wisely, making decisions about what appliances to buy and why, how to best cool your home, etc. 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. I felt that I was good at science and physics in general before taking these classes. _ Hope this helps, and I hope you have a great time in intro physics. r/AskPhysics A chip A close button. I’m 100% sure the sun will rise tomorrow. Well closest I've found to the science that Walter Russell taught is from a person called Ernest Norman. You might choose the CMB rest frame as your "universal reference frame", for instance. This is like universal physics so it's the same everywhere. 401 subscribers in the viXra_revA community. 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. I am looking into systems of natural units, physical units of measurement based only on universal physical constants. See the rules before posting, and the subreddit wiki for common… Posted by u/Megabobster - 82 votes and 15 comments The universe is a stage, the particles are the actors and the laws is the script. Mark and analyse the difficult/ incorrectly solved Questions. I have a nice standard physical Casio-FX991ESPLUS calculator which has numerous calculators but it can be problematic to use that small screen. It really is an amazing subject. Hence, the elliptic or hyperbolic trajectories. 25M subscribers in the askscience community. I've tried taking introductory mechanics, as well as introductory physics 1 and 2. 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. 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. Getting to the introductory college level, you will need single-variable calculus at least and pre-calculus. 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. Source: Just hired as a paid physics tutor, though I've been tutoring students in my spare time for months. The MWI is conjecture. It says simply what happens in a descriptive way but says nothing about why it happens. So what would be an absolute reference? A "universal common reference frame" is about as close to absolute as it gets. For the math to work, things cannot be real. Study conceptual physics online free by downloading OpenStax's University Physics Volume 1 textbook and using our accompanying online resources. 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 Open navigation Go to Reddit Home. His playlist pretty much covers it all. It is available in English and Hindi medium. The laws of physics were noticed by observation.

Other species could have found different ways of describing such phenomena but the phenomena they are trying to describe is the same. 5M subscribers in the Physics community. First, when you're talking about "number systems" and "bases" they're just a representation of a number, like Roman Numerals are also a representation of a number. On the other hand, there are "laws of nature" which, by definition, are prescriptive and which are "obeyed Posted by u/amygdala73 - 9 votes and 9 comments Unlike us AI doesn't need to 'know' physics to make it work. Apr 29, 2021 路 The goal of constructor theory is to rewrite the laws of physics in terms of general principles that take the form of counterfactuals — statements, that is, about what’s possible and what’s impossible. 0 GPA, even after taking quantum mechanics, stellar radiative transfer physics, atomic nuclear physics, and particle 2. The grading breakdown (which is mostly universal across the university physics sections) was 80% exams, 5% recitations, 5% online homework, 5% pre-lectures and bridge assignments, and 5% clicker quizzes. -GmM/r is only valid outside the sphere (the same as the potential of a point mass, see below shell theorem). 101K subscribers in the ScienceUncensored community. Even in classical mechanics what you see is systems evolving in time. The physics classes im taking now is one focused on oscillations and waves, and the other is intermediate mechanics, where this week we’re going to move on to Lagrangian mechanics (as opposed to Newtonian, which we studied in physics 1). 5K subscribers in the QuantumInformation community. The quintessential example is Newton's law of universal gravitation. Michael Van Biezen on YouTube has some great videos for calculus and physics. 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". The equation of state isn’t enough to know what the final state looks like. 469 votes, 42 comments.

Computational physics has also become huge, and these two field are probably the biggest two non-academic fields for physics graduates. And yes, Hydrogen-powered, Rocket-propelled space flight is absolutely a thing, but it doesn't have a lot in common with commercial passenger flight as we It's certainly not something that flows linearly from past to future without beginning or end, and special relativity tells us there is no such thing as a universal, objective "present. The Copenhagen interpretation isn't conjecture, it is physics. Nope. 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. Is the statement, “there are no universal truths” a universal truth? If it is universal then it is a contradiction and cannot Reddit has been pretty great with resources, as well as the Freenode IRC for #physics. 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. 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. yeah you pretty much hit the nail on the head, as far as I can tell you’re understanding the interpretation correctly. - Nuclear Physics is a bit like the Particles topic, as there isn't too much maths involved. Maximizing efficiency isn't a new idea either, but there isn't a lot of gains on the front in the horizon. I suppose I can seek out the physics professors emails. We don't really know why our universal physics work, we just operate with it as a fact of matter. They might be redundant at times but usually each question is approaching the concept from another angle. Physics. Walter Lewin (MIT ex-prof. There are "laws of physics" which, almost by definition, are purely descriptive. Let us discover together the possibilities of our multiverse.
