i wish i knew how to use gimp well
i would use photoshop if my subscription didn't run out
i'd just use paint.net
i forget paint.net is a thing
I've been using photoshop so long paint.net is like a blur to me now
I fell for the "do everything in a browser" meme
So I use https://pixlr.com/editor/
Where's your browser based video editor?
reggie became a cat
I just use the robust Youtube video editor Kappa
i should have used mspaint and just manually colored with inverted colors and a white background
Just freehand it next time, and scan it in
Not-so-rich art boi can do it definitely

mspaint is a professional tool
in browser video editor is wevideo
windows movie maker is also a professional tool
I prefer adobe premiere
The Real Mastermind
Holy fuck, that tutorial was more worthless than the fourier series one.
Russian dude I could not understand whos writting was unreadable. Good thing I already understand inner products and the Grahm-schmit procedure
The non mathphys people who did not take linalg 2 are fucked for quantum mechanics
why do you even need fourier series?
Waves
I assume
Until it turns out quantum particles were never waves to begin with
So, give or take 20 years
everything is a knot of quantum bands wrapped into 27 micro dimensions
Basically my phd thesis
Pika, I'm not looking for a "real" explanation
But how is it that fourier series are used in so many god damn places
Ask me when I am taught them
In 3 months
as a signal processing focus, i barely know what they are because we never use them
It's just weird to me, how that maths concept that we learned in HS is so integral to everything
I am expected to know them now, but not getting taught them until the end of calc 4
Leg, shouldn't that be all you learn in the signal processing world?
no i learned fourier TRANSFORMS
which are much more useful
We also need those
I mean, it's all related
All low frequency signals are essentially periodic after all
if i'm remembering correctly, the Fourier Series is a fourier transform but discretely sampled
Something like that
or is that the discrete fourier transform
Sounds not disimilar to what we did
Since we went from a sum to an integral
To get to transforms
series are for periodic signal and transforms are for not, but you can just take the transfomr of the periodic signal anyway
At the end of the semester, they'll teach you how typing "fft" on a computer is 100x more efficient than everything you've done all semester
Doubt iy.
Calc 4 is not computers
i learned the math behind fft in my last signal class
So hand worked out fourier series
It's a signals processing thing, it's just funny how fft works
Physics dhould just fuck off and let us learn the math needed first
Oh, I lowballed it by saying 100x
I forgot it was this big of a difference
you can actually take symbolic fourier transforms in matlab
no need for fft then
unless you are using real data of course
idk, I like it when data takes months to compile

i posted that at 3 am
no 2
i woke up really early
