Yep! :) This stuff kinda blew me away (in a good way lol) when I was in my EMC (Electromagnetic Compatibility) EE course, learning what was really happening. Finally I had a use for all those years of calculus classes! LoL

Summoning Cthulhu would be very much in character for The Twiggle.

@BigBuggyBastage  
This is the line of math that solves for the total force applied by the electric and magnetic field?
 
I named my oc after Hendrick Lorentz btw. I learned about the fathers of QED through PBS.

@Lawrence Alpaca  
Oh yes, very much so, when working at the ‘fundamental level’. As a former EE professor once said to me, “they explain everything.” :)
 
Lorentz laid the groundwork for Einstein’s theory of special relativity, just to put his “status” into perspective. But I know him best for the Lorentz force, better known today as the electromagnetic force. Some like to argue whether Maxwell or Lorentz derived the equation first, but OMG, that period of time had so many brilliant minds, it’s hard to pick a favorite. That equation is:
 
F = qE + qv ⨉ B

@BigBuggyBastage  
Are these used in electrical engineering? PBS space time keeps going back to the maxwell equations, they also frequent the work of Paul Dirac and Lorentz in electrodynamics.

Let me introduce you to my friends called Maxwell’s Equations…. ;)
 
Also ∇

@mathprofbrony  
I’m am architectural engineer, I mostly do polynomials, rates and ratios for mixing compounds, ohms law, deciding how many materials I’ll need etc.
 
All the math I know is pretty much entry level for a science major.
 
Don’t worry, i love people who know their shit and wear it.

@mathprofbrony
 
And just to make things as clear as I can without going into major detail:
 
₂ F ₁ (a,b,c;z) is just a certain four-variable function.
 
In this example, the arguments are given the values a = 1, b = 2/r, c = (2+r)/r, z = -e^{(v-V), where r, v, and V are some other quantities.
 
The first line asks for the derivative of this function, with those arguments, with respect to v, in the same way you might use the Chain Rule to get dy/dt if y = f(x) and x = g(t).
 
Okay, I’m done I promise. :})

@infinita est lux Solis
 
You guys can do it! Thoughtful practice really does lead to improvement, just like with any skill!
 
Don’t worry about not understanding this, this here is some seriously hard math. I wouldn’t expect any but a few senior-level students and up to understand what’s going on here.

@Lawrence Alpaca  
And I was born with dyscalculia, I can bearly do multiplication, and here I am at my last year of high school.

@mathprofbrony  
I have no clue man, thanks anyway.
 
I thought you meant the surface of shapes in more than 3 dimensions, which for all I know that’s what you’re talking about.
 
I’ll be lucky if I CAD math

@Lawrence Alpaca
 
They might get used for that, but without context it’s very hard to say.
 
stares a bit, checks Wikipedia
 
…ahah. I get it. This is taking the hypergeometric 2F1 with certain specific arguments as a function of v, and differentiating it with respect to v. The successive lines are equivalent expressions, so it’s giving an identity saying that the derivative of the first expression is the last expression.

@mathprofbrony  
You mean like the topology of extra dimensional shapes?

Huh. I never noticed, but the math here is apparently identities involving hypergeometric functions.
