Fair enough, just hoping one of you retards at least could be half smart.

Uhhhh Andrew Dotson's vids are good

it's just a 4D matrix EZ

>function that takes two vectors
Vectors aren't tensors and vice versa. Vectors are generators of parallel transport, or directional derivatives.

>>11587060
>Vectors aren't tensors and vice versa
Your quote doesn't imply that

>>11586834
>but no real analysis yet

Learn that first. Priorities.

I fucking hate you so much you disgusting faggot nigger brainlet

>>11587060
Since the dual of a covector can be thought of as a vector, then a vector is essentially just a (0,1) tensor.

what ?

>>11588138
He's technically not wrong, since a (0,1) tensor is a map that takes a covector to scalar, whereas a vector is an element of a vector space, but it's so overly pedantic.

This doesnt matter if the content is good.

Seconded in theory, but if you don't know shit about topology, straight manifolds will be rougher going.

Please stop talking. Such a pathetic post.

I know it makes me a disgusting piece of shit, but it's worth it.

>>11588155
how about gay manifolds

Relax buddy, your post explained the idea of tensors to a high school student. You didn't really describe them at all.

>>11588234
yes, that's the point

>>11588183
Have you considered just not replying?

>>11588185
They use lube

Anyone knows some good books for applied instrumental engineering (electronics / chemistry)? Like building NMR and other analytical machines

jänich, vector analysis

>>11588249
I did consider it, but that didn't sound like fun.

>>11588249
Just curious, you're the same dude who's replying with Remilia Scarlet pics in this board, aren't you?

>>11588062
Ok, but how does that shit help me fix my car?

>>11588868
You mean the dude who posts Remimi in /sqt/?
Yes.
I don't post much outside of /sqt/, so you might be thinking of someone else.
