Sub i, sub j
isomorphismes: I hope I can say this in a way that makes sense. One kind of mathematical symbology your eyes eventually get used to is the “Σum over all individuals” concept: Yes, at first it’s painful, but eventually it looks no more confusing than the oddly-bent Phoenician-alphabet letters that make up English text. I believe there is a generally worthwhile pearl of thought-magic wrapped...

"To be the Bat, or not to be"
To Bat, or not to Bat, that is the question: Whether ‘tis Nobler in the mind to suffer The bombs and insanity of the Joker and Riddler, Or to kick their asses against a Sea of corruption, For who would bear the whips and scorns of a Catwoman,  Th’ Joker’s wrong, the Penguin’s contumely The pangs of a Killer Croc, the law’s delay, The insolence of Azrael, and the...

The Pokemon Field Guide →
POP QUIZ HOTSHOT So you’re trekkin’ like Charles Darwin and going out in the wild, untamed region of Kanto/Johto/Sinnoh/don’tcarewhere with no Pokedex (prolly because it doesn’t exist yet at this point a la Charles Darwin’s era, or won’t exist ever since you want to be realistic and stuff). What do you do? WHAT DO YOU DO? Take notes of course. (via Kotaku)

How to multiply matrices
isomorphismes: This is for my homies in math class. Mathematical matrices are blocks of numbers, arrayed in 2-D. (Higher-dimensional arrays are called tensors.) Left “times” right equals target. Each entry in the target is the result of a series of +’s and ×’s along the red and blue. A long sum of pairwise products. Your left hand goes across and your right hand goes up/down. where . There...

isomorphismes asked: > [Re eigenvectors] mind = blown. so that’s why these things are important (outside of rootfinding problems).

Root-finding problems end up corresponding to most of those applications (not including the SVD ones). =)
