TL;DR Summary: Seeking good simulations to build my intuition Hi everyone, I am currently teaching myself classical mechanics, and am 3/4 of the way through "Vibrations and Waves," a textbook from 1971 which was used in the MIT course. It's going okay - I feel like I have a decent grasp of...

Hi,I'm a student in Romania and I want to know the steps for becoming a physics teacher. Do you need a master degree or can you teach with a bachelor's degree?

This trend is likely to drive a lot of misguided threads on science forums - IMO. Trend: https://www.cnn.com/style/article/multiverse-movies-newfound-popularity/index.html

Hi everyone! Merry christmas first and I hope you're getting great rest with close ones around :) Well, as title may suggest it, I will graduate soon in physics and I'm not sure of the next step in my academic curriculum. I like theoretical physics, I've touched upon most fondamental physics...

I have tried ChatGPT, an artificial intelligence system, to ask hard questions. Me: What's the best interpretation of quantum mechanics? ChatGPT: Quantum mechanics is a fundamental theory in physics that describes the behavior of matter and energy at the atomic and subatomic scale. It is a...

TL;DR Summary: Questions regarding the book "Modern Classical Physics" by Thorne/Blandford Hello, I'm going through this book and on pg. 127, regarding equations of state, there is a parameter, t (explicitly stated: "not to be confused with time"), that uses hyperbolic functions to relate the...

Hello everyone! Events in my current webnovel have reached the limit of confidence in my physics reasoning, so I'm here to ask for confirmation of my estimates of what would happen from experimentation with force fields. While the setting is fantasy/magic based rather than superscience, I still...

As a hobbyist, studying physics is deeply pleasurable. Yet, I never seem to find anyone discussing this? Discussions on the merits of learning physics always focus on its practical utilites. Are you aware of any books or articles where physicists discuss the deep pleasures that come from...

I'm confused after 2 minutes of this video on acceleration; It starts with telling us that a car acclerates at 8m/s/s for 5 seconds. Then it gives a data chart which includes the car's position at each time interval. The data is as follows. O seconds; O metres 1 second; 4 metres 2 seconds; 16...

This is a confusing subject for me. It's like only getting half of the story. Reading physics but not understanding how it works in chemistry makes it nonsense to me. Imagine we are creating a silicon-based semiconductor. They have covalent bonds between them, with each silicon atom having four...

I'm curious to get people's opinions about whether this is interesting enough to write up for submission. I arrived at a set of coordinate transformations that are different from the Lorentz transformations, but which produce a coherent mechanical framework. It gives a very beautiful physical...

Hi all, I've been working in healthcare in some capacity for 10+ years now and started school a little later than your average undergraduate (started at 26). I caught the math bug and did well in my lower-division mathematics and physics courses and I am currently finishing up Classical...

How did you find PF?: Google Search I am in 8th grade and 10 hours a day free time and i am highly motivated to learn some particle physics. What should i start with?

I am not sure if this is the right place to post this, so if not sorry in advance. I am a second-year physics major, thinking of switching to mathematics. I have always been interested in both, but I could never be sure whether I could become a mathematician. Understanding physics was...

Are they assuming that E = K in physics for scientists and engineers with modern physics, but I though E = K + U?Many thanks!

I'm completing College (Trig-based) Physics 1301 this week and enrolled in University (Calculus-based) Physics this January. I'm also taking Calculus 1 in parallel. My question is: How similar / different are the two classes, besides 2425 being Calculus based ? Will 2425 (University Physics 1)...

Hi! I am looking for a (recent - about 2020 or sooner but anything is welcome) meteorology textbook that actually explains things in detail. I am specifically interested in tornadoes like everyone else, but I have a solid physics background and want to actually learn about them. Does anyone know...

Hello, I am working on a theory for a Great Pyramid power plant and I need some help understanding if my current hypothesis is even possible and how to calculate how much water will fill the upper structure. I believe the water system to work as follows: An aqueduct delivers a steady flow of...

In my late twenties, currently working as a data scientist in the UK, looking to sit A level maths, further maths and physics as a private candidate (not going through a distance learning provider) and pursue a joint degree in physics and computer science (which I know both St Andrews and...

I've got no real physics education but I am interested in it from a popular science and layperson level. If anyone is able to help with this thought experiment. My question is, on a given microwave power setting and a fixed duration, is the heat transferred to the contents largely constant...

Greetings to all. I'm looking for the best textbook for introductory physics that has clear explanations and is problem-oriented. I'd also appreciate any recommendations for textbooks for the AP Physics 1 exam.

Hello everyone, I'm looking for The Feynman Lectures on Physics including Feynman's Tips on Physics: The Definitive and Extended Edition (2nd edition, 2005) for a discounted price. Any suggestions where I might look for one?

While studying motion of car on banked curve, I was wondering, what will be the vmax when theta is equal to 90 degrees or is close to 90 degrees as it happens in a well of death which is organised in a village fair. On a banked road with friction present, vmax is given by: if we put theta = 90...

HELLO ALL, First off, my apologies if this topic is redundant, but I was wondering which programming language is widely applicable to a physics career. What positions in a Physics related career use what specific languages? What is one's best option if one is pursuing a research position versus...

We are seeking to design a project where we use a simple pendulum and a motion sensor (that will give us velocity) in order to study centripetal acceleration by essentially changing the length of the pendulum for each trial. This felt simple enough, however our professor insists that we would...

Is it a good or bad idea to mention that I am a full-time physics student while simultaneously a full-time data scientist employee while doing physics research too in my SOP for grad school? Is it seen as too confident or bragging? Or it helps me to say this? Does it make it sound bad if I...

I was reading about the FTX CEO, and it turns out that he has a degree in physics from MIT - and evidently there are a lot of folks that have taken this same education-career path. Is physics a degree a good path from quarks to quants?

I want to watch and learn more n more physics concepts with the help of animations, please tell me where can i get more n more videos like this. Such as bernoulli's theorem

What I have already attempted is on my Ipad and I don't know how to upload it on here. With hope of help DJ

What I have done is on my Ipad that I cant upload or at least don't know how to... :/ With hope of help DJ

Basically the air works like a spring, it always tries to get back to its resting state. And it's like Hooke's law, the more it deforms the more elastic potential energy it has. That's why the faster you are, the air resistance is greater. Thinking in this way, I imagine that in fluid mechanics...

Whenever I am posting anything related to "life" it got deleted! Does life not related to physics??

As QP says it is uncertain that where you found electron. But its not the same phenomena that one fan blade running so fast that you cant see where the blade is. You can only see the blade on a particular position if you use high resulation camera and its position depend on when you take the...

In 2017 I graduated with a B.S. in physics and went on to a physics Ph.D. program in the fall. After six months, though, because of mental health problems I left grad school on a "medical leave of absence" from which I chose not to return in fall 2018. After job-searching for a while, I settled...

An example of physical applications for the gamma (or beta) function(s) is http://sces.phys.utk.edu/~moreo/mm08/Riddi.pdf (I refer to the beta function related to the gamma function, not the other functions with this name) The applications in Wikipedia...

TL;DR Summary: Using the surrounding airflow to deduce the physics around UAP/UFO Now that NASA is in the mix for investigating UAP/UFOs - I started wondering at what their approach might be. I'm thinking they might be able to work from the outside in, toward the object/sensor(y) artifact...

Hello. I have been a member on this forum for quite some time and I came here because I've always had an interest in science, particularly physics. When I was in Junior High, I did very well in my science class but by the time I got to college, I wanted to make money. However, I realized that...

I'm taking AP Physics C Mechanics in school. And I have spent the most time studying for physics than any of my other classes or extracurriculars. I study by doing reading the book, working out sample problems, doing homework problems my teacher assigns us, the concept questions at the end...

Hi everyone, I finished M.Sc Physics by "Research" at a UK university during the academic year of 2015. I am an international student from India. As I did not do well in my oral presentation defending my M.Sc thesis (but it was not worst), as a result, I got a pass degree. Before the day or...

If we noticed, when we released wind from our mouth with a constant velocity ,Why is the speed of the close part of our mouth is maximum speed and while gradually moving away is also gradually weakened until it is zero? How it can be resolved using in mathematical expression?

A V-shaped tube with a cross-section A contains a perfect liquid with mass density and length L plus and the angles between the horizontal plane and the tube arms as shown in the attached figure. We displace the liquid from its equilibrium position with a distance and without any initial...

Hi, I am a senior at a large research public university in the US (UC Davis). I really want to go to grad school but I am not sure if I should apply this year. I am only 19 years old (I graduated high school with an associates in physics) so this is only my second real year of college and I...

Hi All, I am currently a third-year Ph.D. student working on PET image processing and tracer kinetic modeling, and about to graduate in two years. After three years study, I developed a high interest in clinical-related projects and found medical physics path is very suitable for me. I wish...

We did a lab in class on how to calculate it but he collected it and its days later, can't remember how to attempt it.

I'm not sure where to start, I feel like I'm missing the mass but it is not listed.

I 'v worked as a physics teacher in a famous senior school since I got my degree in 1996. And, reading is one of my loves.

I'm currently a freshman physics major coming into university from an early college high school, so I was lucky enough to have some experience taking college level physics courses before I came to university. I didn't think that those courses were rigorous enough in comparison to what I've heard...

Is there any use for this concept in classical branches of physics? Can it be of any help for a physicist in resolving problems (or, at least, in resolving them more efficiently when compared with traditional methods)? The word «classical» means exactly that, i. e. mechanics, hydrodynamics...

I am not cooking up a torture device or a weapon. In fact, I have been spending time with skeletal models. I just want to be able to create the ability to perceive pain. Even if I were to try to work this out myself and get some kind of answer that relates to physics, how would I know for sure...

Summary: For anyone that might have started off in physics but for their head turned by engineering I am just wondering if there’s many out there that started off in physics before discovering engineering was more for them, what made you switch? My degree is in engineering & physics and I...
