I wonder if the birds know the concepts of homeomorphically irreducible trees.

Here I am satisfied with Multivariable Calculus up my sleeve.

Electric field superposition, expressed in terms of a non explicitely defined charge, but rather densities of charge along vectors. The stylized RHO stands for E/q sub k and both the u and v stand for the function that defines the charges. That is why it could be decomposed into a difference of densities, and also why, at the end, Fluttershy wrote the generalization as a matricial system of linear equations…
 
I have discovered a truly marvelous proof of this, which this comment field is too narrow to contain.

Yup, looks like a Gauss’ Law problem to me.

1/4piepsilon ₀ and rho ₀ tells me this is electrostatics… and that’s about all I know about it

Looks like vector calculus to me.
 
I remember studying that shit when I was completing my BS degree in applied mathematics (BS in both senses of the term, that was before I picked accounting), but I’ve pretty much forgotten all of it now.

I know

And a reference to Dirty Harry

Mhm… According to my comprehensive knowledge and calculations… This is total hieroglyphs.

I wonder what this mathematical equation even means. Also…

This video reminds me of the opening scene of Wes Anderson’s Rushmore. And that reference from Regular Show.
