Hi all, I'm doing undergraduate research this summer, and a few times I've been told to calculate a term with the following form: ∈abcdpaqbkcsd, where p,q,k and s are four vectors (four-momentum, spin, etc). Now I know this ends up calculating exactly like a 4x4 determinant, I'm just not quite...
Specifically this one:
I've been asking several question's about the weak force to my professors, and both on here and PhysicsSE and it seems impossible to get a consistent answer as to what weak hypercharge, weak isospin actually are with any degree of physical-ity.
So I suppose this thread...
Hi all, how much merit does this answer have on Quora? There also an identical answer on Physics Stack Exchange so it'd be nice to confirm or deny the validity of these.
Thanks!
Hi all, I'm just curious about the weak force and how it works.
If quarks and electrons both have weak iso-spin and are constantly whizzing about next to their neighbour's (especially so inside a nucleon), what prevents say, the up quarks from emitting a W- boson everytime they are near a down...
Hi all, so I'm not sure if what I'm asking is trivial or interesting, but is there any general or canonical way to interpret say, The follwing operator? (Specifically in the study of quantum mechanics):
A = 1/(d/dx) (I do not mean d-1/dx-1, which is the antiderivative operator )
How would...
Yes I understand orthoganality of functions. I'm just wondering if for any specific sets of functions there happens to be any interesting geometric properties of those functions as well.
Hi all. So to start I'll say I'm just dealing with functions of a real variable.
In my linear algebra courses one thing was drilled into my head: "Algebraic invariants are geometric objects"
So with that in mind, is there any geometric connection between two orthoganal functions on some...
Hi all! I'm currently working on a graphics/physics engine. The following Wikipedia page was extremely helpful in making rectilinear collisions look natural: https://en.wikipedia.org/wiki/Elastic_collision#Two-dimensional
Specifically, the very general vector form of the equation on the bottom...
Hi all! Sorry I didn't specify the degree of rigor of which I wish to understand the math required for the physics.
My goal is to understand these principles and domains of math for GR & QM analogous to how much I understand the relationship between Calculus and kinematics, or Linear algebra...
Hi all! Been a while since I was on PF and I greatly regret it. Forgot how great the community was. Anyways on to my point.
I'm going into my second ywar of post secondary and planning to major in physics, and have the eventual goal of understanding both General relativity, and Quantum...
I am currently writing a c++ program to calculate the Value of the Reimann Zeta Function, The problem is At the state its at, when you input a number a + bi it only gives the correct answer to values of a > 1. Can anyone show or link me Riemann's Analytic continuation of the Function so it...
Say the function f(x) is (off the top of my head): x^3/(1-n)^x
How would we go about finding the zeroes g(x) of the sum of From n=0 to +infinity? Or am I asking all the wrong questions?
