Pray let us indulge in a random images bread
If one of these had to happen to you, which do you choose?
A visualization of some of the most common linear transformations (basically what a matrix does to a vector). If you're interested, this guy has a great series of short videos on the topic that start from scratch and provide great visualization:
i sort of know what a matrix is (ive forgotten matrix manipulation, or at least the little i didnt, only basic sum of two and figuring out missing things). but how does a vector and a matrix even work together?
Are you familiar with functions in general?
Like say, y = f(x) = sin(x)
or y = f(x) = x^2?
Well, I matrix is actually a function, except instead of taking in x as an input, it takes in vectors, and instead of spitting out y, the output is a new vector
The simplest example is the identity matrix as in pic related. It takes in a vector (in this case, a length 3 vector) and the spits out that same vector. It's sort of analogous to the function f(x) = x.
Interesting question. I assume you mean, how does it keep the vectors in the same direction after you apply it? Well in most cases it does not; the vector is pointing in an entirely different direction. But most matrices (iirc) have a set of special vectors that still point in the same direction after applying the matrix, called the matrix's eigen vectors. I'll see if I have an image illustrating this

do you suppose the mooses had anything to do with the fire?
Maybe some one else has never seen it you selfish prick. And how does that define random? When he said random image thread he likely meant scroll through your folders and choose a random image.
did you just greentext a phantom kek?
a cinder block is vastly different than concrete, rats can scratch their way through cinder blocks because they are loosely glued together. modern concrete would probably take years to be scratched through, and that's if the teeth and claws were able to last that long under the abrasive and alkali nature of portland cement and aggregates.
Bill Nye the Social Justice Warrior guy, he abandoned science to pursue a divisive, anti-science, anti-reason, anti-empiricism, anti-male, anti-white, corporate, consumer culture, social and political ideology.
Bill Nye went from being cool, with a great legacy to a complete human piece of shit for lighting his legacy on fire in ONE EPISODE.
He should kill himself.
