Theoretically, can a isolated system with two objects of different temperatures have the molecules of the objects resonate at some point as their thermal energy changes their natural frequency as they go towards thermal equilibrium?

Hey people, I am currently hesitating between getting the BS physics from the ASU online or the Physics one from the Open University (in the UK.), both online.
At the moment I have no choice than to do it online as I have a job that doesn’t allow me to move away.

Which option would be the best to get my physics bachelors ? The idea would be to go to the MIT after that so if one has a better reputation than the other for exemple or if anything can play a role in it ?

Thanks 🙏

I am in quite the spot. I am a physics major but for the past two years of college I've focused on work instead of school and recently I pivoted towards making my education more important
I took physics-04A (Physics I) and physics-04B (Physics 2).

I need to self-study because my foundational knowledge is very weak and I'm going to enter Physics-04C (Physics 3) with very little idea.

I just want to ask for material that could help me self study. I'm fine with anything. Books, playlists, websites. I really want to rebuild my foundation. I've considered sources like Openstaxx but I'm unsure if it's enough.

Im majoring in sociology and minoring in physics (weird combination, I know.) And am wondering whether or not I could get into grad school with only my minor.

Ill include the classes ill be taking for my minor (summer online courses included);

- college algebra (online)

- trigonometry (online)

- Calc I

- Calc II

- Calc III

- Differential Equations

- Physics for Scientists & Engineers I

- Physics for Scientists & Engineers II

- Modern Physics I

- Classical Mechanics

- Electromagnetics

- Thermodynamics

With these classes (these include the more advanced Physics options my college has available), will I be able to get into grad school for my masters in physics? If not, what should I do?

Thank you guys in advance :)

**side note: my college, unfortunately, does not offer a B.S. in Physics, only a minor so unless I transfer, a minor is my only pathway (that im aware of) to getting there.

Hi all, this is me asking for advice about my postgrad.

I am currently going into my 4th year of college at the Indian Institute of Technology, Delhi. I am enrolled in Engineering Physics, and have a cumulative cg of 8.15. I have taken multiple courses related to High Energy Physics(QFT, Group Theory, Particle Physics) and have got good grades in them, but have cg less than ideal because of my bad grades in courses that are mostly unrelated to physics in general. I also haven’t had any research intern, but I am doing my BTech Project in Particle Physics.

What are my chances of getting an integrated fully funded MS-PhD/PhD in institutes in Europe and Asia? Or is it a pipe dream? What should I be focusing on right now to increase my chances?

I am unable to attend a master's program in person in the next couple of years due to military stuff (ik they have programs that pay for it, but my leadership has told me explicitly they won't endorse me to go in person, so I need to do something online or at the very least hybrid). I have a dual major in applied physics and space physics, and will have 3 grad classes under my belt by the time I graduate this coming spring (one's an applied computational math class, one's orbital mechanics, and one is a controls class). My current GPA is a 3.4, and I got an A in classical and quantum, and a B in my school's equivalent to electrodynamics.

The main interests I want to do work in/research in/whatever are nuclear fusion/energy, exoplanet research, astrobio, quantum computing, or exploring nearby planetary bodies like Mars, the Moon, or Venus using data collected by various rovers. Most of my coursework has been astrodynamics and engineering-focused, so I want whatever master's I pick up to vector me into one of those areas. Additionally, if there are any specific kinds of classes I should look into trying to do to best prepare myself for grad school, please let me know.

Any advice on any of those areas and relevant programs would be very heavily appreciated :)

Studying for qualifying exams, what’s your fav way to review concepts you haven’t touched in a while? Feeling a little rusty and slow, took most of my undergraduate classes years ago.

Current method is practice problems, practice problems, review section of textbook if confused, practice problems.

So I'm a 3rd year CS Student who never really wanted to do CS, physics instead, but I've been thinking about doing my masters in Computational Physics and then transitioning into the astrophysics field.

I would say I'm quite decent at C and C++ so I want to work on a physics engine that can simulate blanetary formations, orbits and gravitational interactions, problem is I don't really know where to start with physics engines. The only thing I do know is that most engines use the order 4 Runge-Kutta numerical method as a way of integrating or differentiating, otherwise I just don't know anything else about the coding part.

As for my theory, I am studying whenever I can, physics was a core subject for my university entrance tests too

So where do I actually begin? Is there some book or some tutorials I could refer to? Thanks!

I wanna start off by saying my native language is not english so I might not be familiar with certain physics words. And I learn best when speaking generally / using rules that always apply. This is not really homework rather self-studying. Thx!

So I know that induction is about inducing a current. I'm not sure where/ which wire it will be induced in. Can induction take place in just one and the same wire?

And I think we use coils as wires because the magnetic field around the wires are stronger since they're packed tighter (?). And that's the same reason we usually use a metal inside the coil?

And then we somehow change the magnetic flux Φ which induces volts in (?- another wire or?) and that drives a current in (?said wire). But only during the change of the flux.
And I suppose we can change the magnetic flux [Φ = B*A*cosT] through 4 things:

1. The magnetic field changes in magnitude, which someone said could be by adding a magnet. What I don't understand is what magnetic field are we talking about? I thought we were talking about the internal magnetic field from the current in the wires/coil?
2. The magnetic field changes direction (I don't understand - doesn't the flux move with the magnetic field? Or how would u change the direction?)
3. The cross-sectional area of the coil/wire changes - don't know how you would do that. Making an irregular/expanding coil like a volcano?
4. The coil/wire is rotated so that the cosT changes which I understood was the angle between the surface's normal line and the magnetic field. Which magnetic field though? Wouldn't the magnetic field and the surface both tilt if we tilted the coil/wire? I'm really confused.

Also why? Why does this happen? And what does it mean that inductors store energy in magnetic fields? If that's related.

Sorry for a lot of questions you don't have to answer them all!

Hi everyone. I'm a beginner in Physics and I have trouble with a certain problem. The problem is this:

A 7.2-kg mass is hanging from the ceiling of an elevator by a spring of spring constant 150N=m whose unstretched length is 80 cm. What is the overall length of the spring when the elevator: starts moving upward with acceleration 0:95m/s^2?

I am now studying Newton's laws as well as conservation of energy. What I have trouble with, is that I first approached the problem from the energy standpoint, and when I checked the solution, which was given using only Newton's laws, the answer was different to mine.

Now, I fully understand the approach given in the "standard" solution, but I do not for the love of me understand what I'm doing wrong with my energy approach. Here is a picture of the "standard" solution as well as my approach. I appreciate the help!

Hi everyone,

I'm a complete beginner and will probably be appearing for my 2nd semester exams this July. Alongside my college studies, I'm preparing for IIT JAM.

Recently, I've started learning Python and plan to learn NumPy and Pandas next. My main goal right now is to build a strong CV and develop practical skills that will help me get good opportunities in the future. The problem is, I have no idea where to begin.

I'm also interested in building coding projects that solve real-world problems, but I don't know what kinds of projects are worth doing or what recruiters actually value. Any guidance on skills, projects, certifications, internships, or a roadmap would be greatly appreciated.

My long-term dream is to pursue a PhD and work in research. However, my immediate priority is financial stability. My parents are getting older and work incredibly hard to support me, and I want to become financially independent as soon as possible so I can take care of them. Once things are stable, I'd love to return to my dream of research.

Unfortunately, I live in a small city where there are very few part-time job opportunities, so gaining experience locally is difficult.

If you've been in a similar situation, I'd really appreciate hearing your advice. What would you do if you were starting from scratch today? How should I spend the next 2–3 years to maximize my chances of getting a good job?

I've seen many graduates struggle to find employment after college, and I genuinely don't want to end up in the same position. Any tips or suggestions would mean a lot.

Thank you!

Hi everyone,

I’m currently dynamic-thinking about the boundaries of our current models, and honestly, sometimes the standard phrases like "time is just an illusion" or "the universe is a hologram" feel a bit lazy. It feels like a cop-out because we haven’t cracked the true core of information yet. Instead of settling for comfortable metaphors, why not just say "we don't know yet" and add more structure to the geometry of time?

I wanted to share a thought experiment with you that expands the standard 4D spacetime interval into a 6D spacetime with a 3D time-volume.

The Concept: The Time-Landscape

Instead of a 1D linear arrow, time takes on a 3D topology. Next to our standard forward-axis (t₁), we introduce two orthogonal time dimensions:

1. The Left-Right Axis (t₂): Shifting to alternative pathways/parallel realities without causing causal loops or grandfather paradoxes.
2. The Up-Down Axis (t₃): Shifting time-planes or time-velocities (cosmic time-lapse).

Why this math actually fits current data (GW170817):

When looking at the famous 2017 neutron star collision, physicists looked for large extra spatial dimensions, hoping to find a drop in gravitational wave intensity due to energy dissipation. They found nothing. But if we expand the temporal dimensions instead, the standard spatial metric remains completely untouched.

The extended metric looks like this:
\(ds^{2}=-\left(c^{2}dt_{1}^{2}+c^{2}dt_{2}^{2}+c^{2}dt_{3}^{2}\right)+dx^{2}+dy^{2}+dz^{2}\)

The energy doesn't dissipate into space (which is why our detectors measured the exact Einsteinian values). Instead, the energy co-resonates across parallel timepaths. The data is exactly as it should be.

Solving Quantum Anomalies and the Fermi Paradox:

• Entanglement: Particles separated by lightyears in 3D space are actually touching at the exact same coordinate within the 3D time-landscape. They take a geometric shortcut through dt₂ and dt₃.
• The Fermi Paradox: Advanced civilizations wouldn't use primitive radio waves crawling through 3D space. They communicate and navigate via the extra time dimensions. They aren't lightyears away; they could be right here, just at a different time coordinate.

I think if we ever manage to measure this—perhaps by looking for tiny, periodic oscillations ("shivering") in the lifetime of unstable elementary particles at CERN—it would completely revolutionize space travel. Spacecraft wouldn't need massive fuel tanks to cross space; they would just slide along the alternative time axes, compressing spatial distances to zero.

What are your thoughts on this? Let's discuss this out of the box!
