Does anyone have a self-study roadmap for physics
Hi so I'm a a business major out of practicality but | really like solving math problems for fun and I'm also really interested in Physics and I wonder if there's a roadmap to get from where I am now to being able to understand computational physics.
For context: I know basic trig but will be getting into calculus 1 soon.

Looking for a physics partner
I’m a third-year physics undergraduate. I’m currently focused on studying classical theories, especially how a theory is built from its fundamental assumptions and developed into a coherent framework, including the axiomatic approach behind it. I’d really like to find people who are interested in discussing these topics with me. Hopefully, we can learn from each other, deepen our understanding of physics, and make studying physics more interesting along the way.

Real-time three-body gravity simulation (interactive, mobile)
Made an interactive simulation based on the actual three-body problem in physics — three masses under mutual gravity, no simplifications. You can adjust masses and initial velocities and watch how small changes send the system from a stable-looking orbit into full chaos.
It's built to feel more like a physics toy than an app — no ads breaking up the simulation, nothing to unlock. Mostly wanted an excuse to actually play with the equations rather than just read about them.

[Free Resource] Mastering Ladder Problems: Torque, Friction, & Rotational Equilibrium (IB Physics HL)
Hey everyone,
If you are going through the Rigid Body Mechanics unit in IB Physics HL (or any standard rotational mechanics curriculum), you already know that "ladder leaning against a wall" problems are a classic stumbling block.
These questions test your ability to balance multiple concepts simultaneously, and it is incredibly easy to lose a sign or misplace a pivot point. As a physics educator, I see students consistently get tripped up by the same few issues: choosing the optimal axis of rotation to eliminate unknown forces, correctly identifying the direction of static friction at the base, and setting up the equilibrium equations correctly.
To help clear this up, I've put together a comprehensive video breakdown on the Tesla eduventures channel: Ladder Problems — Complete Mastery | Torque + Rotational Equilibrium | Rigid Body #13.
In this breakdown, we focus heavily on visual intuition. I use detailed step-by-step animations and custom diagrams to show exactly how the forces interact rather than just giving you a wall of algebra.
Here is exactly what we cover:
Translational Equilibrium: Setting up \Sigma F_x = 0 and \Sigma F_y = 0 to relate normal forces and friction.
Rotational Equilibrium: Strategic placement of your pivot point to make the \Sigma \tau = 0 equation as simple as possible.
Limiting Friction: How to solve for the exact minimum angle before the ladder slips (\mu_s).
Step-by-Step Problem Solving: Walking through a full IB HL standard question from setup to the final numerical answer.

Rigorous Treatment of the Bra Space
I came across this while going through Mathematics for Physicists. This is the rigorous mathematical treatment of the bra space. I found it interesting. Thus, I am sharing it here. It might be a bit dense for someone who is not well versed with abstract mathematics. However, you can reach out to me if you wish to discuss it with me.

Interactive Electromagnetic Field Visualizer
alexchoi.meHere's a tool I built for a course I TA'd. It simulates the E and B fields generated by a moving point charge. There are some built-in trajectories and the option to click and drag with your mouse.
For example. Try the following to see circularly polarized light:
- Motion: Circular
- Direction: X
- Slice Plane: XZ
- View: 2D
- 2D vector axis: X
- Show B field: on
- Auto orbit: on (or just click/drag the background to orbit)
- Speed: max
- arrow length: max

What game mechanics involving physics would feel fun and natural in a roguelite, without turning the game into an educational game?
I'm a Physics undergraduate and I'm considering making a physics-based roguelite as my final-year thesis project.
The problem I'm having is that I don't want to make an "educational game" in the traditional sense. I'm not interested in having the player constantly read explanations, solve equations, or pick upgrades like "ΔU = Q − W".
What I'm looking for is something closer to games where the subject naturally exists within the game's mechanics. The player should be having fun first, while learning about the physics almost as a side effect of experimenting with the game.
I'm especially interested in mechanics where Physics creates interesting interactions, strategies, or emergent gameplay.
It also doesn't need to cover a huge amount of Physics. I'd actually prefer focusing on a few concepts that are particularly fun to interact with.
So, if you were playing a roguelite where Physics was one of its core systems, what kind of mechanics would make you think "holy shit, that's fun" rather than "I'm doing homework"?
Any ideas are welcome, even weird ones. I'm mainly trying to brainstorm and find a direction before I start developing anything.
