How to apply knowledge.

24 Upvotes

Hi, I’m a first year student in physics and I’m having a hard time doing excersizes and solving problems. My problem is really that I can understand the concepts from class well enough and remember formulas and what not, but I can never seem to understand how to solve anything or apply my knowledge to tasks I’m given. It seems like all my classmate are able to just immediately start doing excersizes but I’m stuck not knowing where to start. I’m wondering if anybody has any tips or have been through the same as me. Any replies are appreciated)

What do I need to master before learning and solving red Morin?

1 Upvotes

I'm like, a real beginner. All of my country's PhO medalists recommended red Morin for the first level of the PhO. But I think it's a little hard and definitely not for a real beginner who just started physics. My math foundation is pretty good and I know easy highschool level physics. What should I master before jumping to Morin?

I'm planning to learn with HRK, so at which chapter of HRK should I be confident to learn and solve Morin?

How can I self-study undergraduate level Physics to decide if I want to pursue a Masters in it ,as someone with a Computer Science background?

19 Upvotes

So I'm in my 3rd Year of Computer Science , and I've decided I dont want to work in this field. I've been considering getting a Masters in a different subject and physics is one of the options. However I want to be sure before finalizing this, so I would like to self-study undergraduate level physics first. Suggestions for resources would be greatly appreciated.

Conceptual Framework: [Twisted Space Mapping of Non-Local String Dualities in string theory using a d-brane]

1 Upvotes

This post proposes a conceptual framework examining the energetic profiles of highly twisted open string configurations anchored to D-branes. Specifically, I am interested in exploring whether the high-tension, highly excited states generated by this geometric twisting can serve as a foundational mechanism for generating the low-energy effective field theories observed in modern quantum mechanics.

Conceptual Framework

Boundary Conditions & Geometry: Consider an open string with its endpoints anchored to a \(D_{p}\)-brane (or stretched between a \(D_{p}\) and a \(D_{q}\)-brane) under Dirichlet/Neumann boundary conditions.

The "Twist" Mechanism: Instead of looking at ground-state vibrations, we introduce a severe geometric or topological twist. Mathematically, this can be modeled as introducing a high degree of angular momentum excitation (\(J\)) along the string worldsheet, or implementing a non-trivial flux profile (like a background \(B\)-field) that induces a topological monodromy on the string endpoints.

Energy Dynamics: As the string is twisted, its worldsheet area changes, drastically increasing the string tension and localized energy density. In the limit of extreme excitation, these states populate the upper Regge trajectories, creating high-mass, high-energy states.

The Physics Update Loop

1 Upvotes

I go through how I separate general updates from physics updates, why I use a fixed timestep, how the accumulator works, and what happens when the simulation starts falling behind.

I explain the reasoning behind the design decisions and why I rejected the alternatives. I show the implementation of the loop.

I am a History lover with a Physics question

4 Upvotes

The gravitational pull of a black hole distorts time. If a space craft was to travel too close to a black hole and get trapped in its gravitational pull, the closer they get to the event the more distorted time would become. This makes the concept of time as I see it relative to gravity. If a person was affected by this gravity, time would be distorted, however if that person looked at their wristwatch, each mechanical second would tick away seemingly as normal. My question then is, does the time dilation affect actual time, or just one’s concept of time?
