A meme is an idea, behavior, or style that spreads by means of imitation from person to person within a culture and often carries symbolic meaning representing a particular phenomenon or theme.
An Internet meme or meme, is a cultural item that is spread via the Internet, often through social media platforms. The name is by the concept of memes proposed by Richard Dawkins in 1972. Internet memes can take various forms, such as images, videos, GIFs, and various other viral sensations.

Delete this image now, or in 5 years, Elon Musk will release the Tesla Rhombus, and force it upon Europe!
Make it higher so it could qualify
Shit you are right, it's just a parallelograyhound
Have you ever seen a square? Congrats, it's a type of rhombus.
A square is also a rectangle.
Indeed. And square is, by its definition, the only shape that is both.
oh they don't appear again, but its generalization, the parallelepiped, does:
it's used to calculate volumes of curved objects. basically you chop down the object into a lot of small parallelepipeds (mentally), and then calculate the volume of each of them small things and sum over them. Done.
to calculate the volume of a parallelepipede, there's a surprisingly simple mathematical formula. If you have the vectors for the three sides a, b, c, then the volume V = (a × b) · c, where × is the cross product and · is the dot product. it's very simple and an effective way to calculate volumes of curved / deformed objects.

where × is the cross product and · is the dot product
pardon my ignorance but what the fuck is a "cross product" or a "dot product"? I assumed at first this was multiplication, but then I saw the dot and realized this isn't anything I've ever been taught

sorry i am too tired to explain in full detail rn
that's fine, and thanks for the links! I just don't quite agree that this is suprisingly simple mathematics :P
yeah it's "surprisingly simple" in the sense that there's a well-defined algorithm to do it. a computer can do it easily, with very little time/effort. anyways, you don't need to think about every problem specifically. "now i got this parallelepiped, how do i calculate the volume?" you can just use the same formula every time.
Sometimes I think about parallelepipeds then when I reassociate I'm smiling and my fiance is visibly wondering what I'm thinking about. "Don't worry hun, parallelepipeds again"

Take a square. Lean it to the side. Rhombus. Take a diamond, let it fall on one of its sides. Rhombus. The world just keeps a-rhombusin, you just stopped a-noticin'
ILLUMINATI CONFIRMED!!1!one!!
clearly you didn't learn, since diamonds are a pretty common shape
In my culture, rhombus is the basis of a vagina pictogram. In my culture, rhombus is every schoolboy's favorite shape.

That one was great 🤣
This is amazing and thank you for sharing. The ability of the human race to come up with different yet universally understood yonic symbols is heartening. Like no matter what place or time, we're all in this together and we will be drawing genitalia.
Hell my dude there's a cave people deliberately carved to look like a vag and it's incredibly detailed.
Humans just seem to love genitals to an alarming but understandable degree
That's even better
This is the cave btw
sigh zip
Researchers believe that the entrance to the cave was a slit, which was then widened by humans.
😏
It is impossible to be mature about this.
Imagine my 14yr old mind seeing and reading about this for the first time
You weren't kidding they even got the cervix lol
Rhombussy
That's actually amazing I love that just a diamond with a line in the middle is shorthand for vagina, it's so universal too I bet if you showed that to any human they'd eventually guess the meaning.

Haven't you guys used a kite before?
Imagine living as a farmer in medieval Europe near a small village and you make MOST of your shit yourself or with help from the local blacksmith. You'd use all kinds of things and ideas that we don't use any more. You need to be creative to solve your daily problems and find ways to do stuff efficiently. Like imagine you'd need to dig out a bit of earth for an "almost square" and need to calculate the area and volume of earth you'll have to move.
I'm not sure what I'm trying to say, but I think modern education is wasted on the modern human.
We are not curious enough. Dopamine hit of figuring out a cool thing requires lots of time, meanwhle videogames and movies are guaranteed in short term.
We are not to blame tho, time to spend bored is simply not something we have; every other moment of our life will be either at work, preparing to go work, or driving to work, afterall.
I predict the farmer dug that square on snow instead of dirt. They certainly weren't farming during mid-winter. Must be boring. I will still be labeling amazon boxes this december.
Come across any rhombus shaped amazon boxes yet?
I will bend some into the shape of one before shipment, just for you <3
The point of the modern grade school education is to give any and every student enough of a education in any given topic to specialize in any field afterwards, depending on interest and opportunities, as well as create voting citizens that can understand at least the basics of any given social debate.
Modern education isn't wasted. Some people just waste it afterwards.
And some people who want to destroy it to keep everyone as ignorant as your medieval peasants pretend that they don't understand any of that.
Also smiths would literally just do that on vibes lmao.
do de ca heedron
Every square you ever met is a rhombus that gave up its art career and got a boring 9-5.
All shapes will be hunted down to extinction until the one and only remains.
Yeah, it's pretty good. But it's not a hexagon, which is the bestagon...

Jokes on you! We're currently in a rhomboid-shaped economy right now!
This person hasn't done math past elementary.
I went up to Calculus I in college (along with some physics and engineering), and I've done a bit of amateur math outside of school ... but the concept of a rhombus was still used exactly zero times.
The engineers prefer triangles, the physicists prefer circles, and the pure mathematicians are usually dealing with weird shapes that don't even have names. Who uses the rhombus?
Right there with you, I didn't use it in analytical geometry, calcs 1-3, diff eqs, or numerical methods. I don't think it would have shown up in my other math classes either. I'm pretty sure the rhombus is nothing more than a happy shape.

I think there's 1 building in Dubai that looks like that?
The word "rhomboidal" exists and you are allowed to use it as much as you like
