Highest level of Physics you are knowledgeable about?

Physics ranges from the older, more basic theories to more modern, advanced ones:

Classical Newtonian mechanics/Kinematics (Study of things like Force, Work, and Kinetic and Potential Energy)
Classical Optics (study of how light moves)
Classical Thermodynamics (Ideal Gas Law, Zeroth, First and Second Laws of Thermodynamics)
Maxwellian Electromagnetism (Electromagnetic theory)
Special Relativity (Study of things traveling at light speed, a more general version of Classical Mechanics)
Quantum Mechanics (Study of subatomic scales, also a more general version of CM)
Quantum Field Theory (QM at relativistic speeds)
General Relativity (Further generalized theory of relativity which explains gravitation)
Particle Physics (Study of fundamental particles)
Speculative Physics (String Theory and Quantum Gravity theories, other theories which are just speculation at this time)

What's the highest level of Physics you feel you are comfortable saying you are knowledgeable about?

I'd say the highest Physics I'm knowledgeable about are Special Relativity and the very basics of Quantum Mechanics.

Nearly all of it, but like you, just the basics on the quantum level. I am big on string theory and am developing an "expanded string theory" that models with fewer dimensions instead of adding them. It's pretty neat.

I would like to know more in depth on electromagnetism, though. I have an idea about that, something interesting.

Advanced understanding of Quantum Field Theory and Particle Physics

String theory is a cult and I wouldn't waste a single braincell on it

[–] Frogarama (12942) 7 years ago

The problem with String Theory is that the math works well but no one knows what the math is describing.

The reason for that goes back to the 1880's and some basic, flawed experiments that are still canon. My Expanded String Theory is an actual functional model, so far. I didn't even consider classic String Theory until I found it in my model, so clearly shown. That's when I named mine with Expanded in the front.

I know that if you have two Nvidia graphics cards you can set one as a dedicated Physx card.

Whats your definition of the Universe? - My claim in that it is infinite and eternal. Although some say I cant make that claim without proof. My only real argument is that you cant create or destroy space, so 1 - the space that is here has always been here. and 2 - space can not end at some point, just like a number line, there is no largest number - you can always add 1. Meaning that you can always go deeper into space.

Whats your opinion?

[–] aliensalmon (5607) 7 years ago

Hmm...you make good points. I'd love to give you a good reply but I need to really think of a good one. It will take some time for me to process it.

[–] gater (199) 7 years ago

Alright, I grew up believing that the Universe was infinite and eternal. I was shocked to learn that this wasn't accepted fact. I did some checking and some scientists think the Universe is finite.
Einstein said he thought it was infinite but later claimed he wasn't sure.

I can not comprehend of a Universe that isn't infinite and eternal. But I need proof. Thanks

[–] gater (199) 7 years ago

Aristotle and Einstein believed in an infinite universe - at least im in good company.

[–] TexasJack (12516) 7 years ago

You're right -- definitions are everything. The current evidence is that the observable universe had a definite beginning and will eventually completely burn out and die. But the "multiverse" model holds that this universe is just one of many, so if you define "universe" to encompass ALL universes, your claim may be right.

Personally, I think there is an endless multiverse and that every black hole singularity in one universe represents a "Big Bang" event in a new universe.

[–] gater (199) 7 years ago

There is one Universe. It means all of space and matter. Eternal and Infinite. The Big Bang just explains how the galaxies that we can see got there, but that was a relatively recent event is the scope of eternity.

I don't get the question. Who determines which area of Physics is higher than the nother?

[–] aliensalmon (5607) 7 years ago

Sorry for the vagueness. Generally the "higher" Physics involves more complex mathematics, and those tend to be more modern than older theories.

Are you trying to brag?!

[–] Greyere (77) 7 years ago

✔ Classical Newtonian mechanics
✔ Classical Optics
✔ Classical Thermodynamics
✔ Maxwellian Electromagnetism
✔ Special Relativity

You don't even know the diff between Special & General Relativity! Former is limited to non-accelerating ref frames.

Both are concerned with space-time distortion near massive objects or at near light speeds.

[–] aliensalmon (5607) 7 years ago

Well, I worded my description kinda vaguely, but I am still correct about GR being a more generalized version of SR, which as you say, applies to all reference frames. I am aware of both theories' concern with space-time distortion. I just wanted to explain the general subject matter in layman's terms.
