Top half is one of those graphics that makes a uni term feel like time simply lost since you could unserstand the concept in 5sec.

Do convolution now!

So simple it's mind-blowing, whoever came up with the way to represent it visually like this deserves a round of applause and a nice plaque in college campus gardens everywhere.

If your package looks like that after shipping, you didn't use enough packing material.

10: pack your box
20: close box then shake
30: If contents of box rattle around add more packing material go to 20 else go to 40
40: tape box on seams and apply shipping label on box but not on box seams
50: give box to courier

What are you packing your boxes with that a shitty delivery company couldn't still make it look like the meme? Reinforced steel?

[–] [email protected] 3 points 3 months ago

It's put into a semi truck trailer where other, many times heavier packages are most certainly placed on top of it. Those packages along with the beating it'll take from the road that desperately need to never be paved with concrete as it goes cross country, it will take some dings. The only way to be sure it's to make sure your package has adequate packing material.

Otherwise your cardboard box will turn into a cardboard sack.

I once worked a stint for UPS doing package sorting. I definitely used that time to take some mental notes for any future shipping of mine. One big thing to pay attention to is keeping the weight/center of balance FIXED. Preferably low to the bottom and centered, but definitely fixed fixed fixed. Packing peanuts might still let something heavy shift around. Some folded up cardboard to keep heavy stuff fixed in one spot can go a long way to keep that box together.

The reason comes down to the belts in the sorting facilities. Some conveyor belts will suddenly tilt up at like 35°. If your contents shift the right way at that moment, the contents will start to use your box like a hamster wheel, counteracting the movement of the belt, and it will stay there doing flips until another package takes a beating helping it, or the jam is cleared. Even worse, it could climb that 35° incline and instead wobble wrong all the way at the top, and come tumbling down 30ft. You grow to learn the sound of a tumbling package, because immediately after the tumble it hits a small metal lip 2 ft from your head, shoots across your work area, and lands where you just grabbed it from. I think the max limit on that belt was 60lb packages.

Auto mechanics, this is specifically why your alternators are always beat to shit after UPS ships them.

This was also 10+ years ago, maybe they addressed the careening packages of death

Why 10, 20, 30, 40, 50 instead of 1, 2, 3, 4, 5?

[–] [email protected] 5 points 3 months ago

Because it's basic.

[–] [email protected] 3 points 3 months ago

if you want to add a line in between. And don't have a fancy text editor

[–] [email protected] 10 points 3 months ago

Because it's been so long since I've done any programming. I don't remember syntax other than BASIC and I'm 80% sure my if statement is done incorrectly.

So you can revise and insert new steps.

Oh no, I ordered something and they're shipping FedEx. This meme is my future.

Haha, sorry, the site bugged out. I meant to say: And thank you for a response to my group chat!! lmao.

[–] [email protected] 8 points 3 months ago (1 children)

they barely fit on my screen lol

[–] [email protected] 8 points 3 months ago

Never before has a meme been more relevant and targeted directly towards me.

[–] [email protected] 4 points 3 months ago

This is so weirdly relevant to me, I used to work as a courier and now I work on radar (which uses Fourier transform to display info)

Once i got an entire toaster delivered on my mail box in an appartment complex, the thing was so crammed in there that to get it out we had to disarm the entire thing

[–] [email protected] 35 points 3 months ago (1 children)

Oh wow I've not had to do a Fourier transform for years but that top graphic is actually incredibly helpful for visualising what it is

[–] [email protected] 13 points 3 months ago (2 children)

Also this: https://www.andreinc.net/2024/04/24/from-the-circle-to-epicycles these illustrations are so helpful, theres a few about halfway though and things just make more sense. i need visual math lol

[–] [email protected] 7 points 3 months ago

You lured me in with the nice gif of circles mapping to sine waves and then suddenly repressed memories of forbidden mathemagicks were returning to me

[–] [email protected] 2 points 3 months ago

Thank you for sharing. This is a great source of you already have a solid background of the basics. The visualisations are great but man, the pace from "what is a circle" to Euler's identity... Whoof! Still looking for a Fourier for Dummies

One is a reversible operation
