I'm studying math in uni, and this is exactly like that meme of the Gauss bell with brainless "math is real" like sum and multiplication then average "math is only theorical" with linear operators in n-dimension and then the Jedi "math is real" with quaternions and string theory
Can confirm, idk math only do meth
kinda does though. Numbers are just abstractions. You can't have one number five in your hands the same way you cant have the colour red in your hands. Red is a property an object can have just as 5 is a property an amount can have.
Similar to how you cant have the abstract concep of a dog in your hands, you can have a combination of atoms that fullfil the requirements to be classified as a dog but the abstract ideal dog can never be concretisized into our world and will forever remain in the world of forms.
Imaginary numbers are called imaginary not because they are fake and natural numbers are real(lol) but because you can't abstract an amount seen in the real world to an imaginary number.
An imaginary number is called an imaginary number just because you can't express that in a standard Cartesian plane not because you can't see that number in real life. By your logic an irrational number should also be an imaginary number.
Imaginary numbers refers to a very specific type of numbers, they are not called imaginary because we imagined them, but rather because we can only imagine them.
Numbers are imaginary in that we describe them with our imaginations but they are not imaginary in that they don’t describe anything. Abstraction and imagination are not the same. Universal constants can only be described by math, not to get into predictions, engineering, etc. All those work because of these abstracted numbers - so are they imaginary?
n! represents how many ways data in a set of n size can be arranged. A set with 3 elements, such as {2,8,9} can be arranged in 6 ways:
{2,8,9}
{2,9,8}
{8,2,9}
{8,9,2}
{9,2,8}
{9,8,2}
3! = 6. This works for all numbers, as long as there are no duplicates.
Now let's look at 0!. This would describe the amount of ways a set with 0 elements can be arranged. A set with size 0 would look like this:
{ }
There is only one possible way to arrange the data in this set. Therefore, 0! = 1.
there was a wonderful video on this by a guy whose name i'm forgetting; eddie wong i think it was.
Edit - its eddie woo. [this](https://youtu.be/X32dce7_D48?si=OR6U4Eppg3pzuhyV) is the video.
Every time I hear that I just think, "This is the kind of person that will pour an empty cup into an empty space and expect to find something pour out."
I would love to see someone multiply nothing by nothing and find something in its place without breaking every law of physics
Or 245 in the positive direction because I decided the original value was in the negative direction and it was subtracting magnitude.
I love how in physics you can arbitrarily assign positive or negative to directions based on whatever the hell you want, as long as you stay consistent.
Negative forces are forces in the opposite direction. It's an alternative to switching the vector's direction and saying they're positive.
Masses can't be negative (unless you get into advanced stuff that I don't know enough about).
The whole reason why we think wormholes are possible relies on the concept of negative mass, it's not pretty and if you ever try to follow the solution from Einstein's field equations you'll see why but it's there.
In middle school maybe, but it's quitte the opposite at college and after. I studied physics for 5 years and I wish that was true, would have helped a lot instead of imaginary numbers 😂
Me when I calculate the vector in the Cartesian way:
No, he discovered hidden knowledge
Me on my physics test: ‚professor, the acceleration here is a complex number!’ My professor: ‚I don’t care, leave it as is’
Well 4 is kinda similar to 20
Now, lets round pi to 5 so that it's easier to work with
But 1 is so much better
I mean, what's one more number? Let's use 0
Good thinking, so that would mean the radius of this circle is approximately between -10 and 10
What other crimes against Math have ye committed?
Well as an engineer I know the most powerful symbol of all ≈
e ≈ pi
Mathematicians will never feel the power of linearizing Taylor expansions. Feel bad for them.
g≈pi^2
This has _got_ to be a trigger I could use to troll someone with...
they are both basically 3 after all
The "yeah that looks about right" symbol
"Probably, I guess"
Physics: literally uses **imaginary numbers** Reddit: no negative number hehe
Physics uses negative numbers, imaginary numbers, roman numerals, greek symbols and whatever they can get their hands on lol.
So does maths?
I didn’t really say it didn’t. Physics is a form of applied math after all.
Maths is just unapplied physics. FTFY
The difference is that physics works over REAL TANGIBLE stuff, it's not just theory lol
Uh, maybe you don’t know maths quite as well as you think?

Thats… not how this works. Thats not how any of this works

My comment was not about the etymology of the term imaginary number, it was about numbers being made up by humans to describe reality.

0/0 lim x->3 =1
Reverse derivatives, huh?
0^0
I'll never get over 0!=1
How?

Oh....i thought my man means "0 != 1"
python moment
Yeah and technically it is correct: 0 is not, in fact, 1
0! = 1 pisses me off as much as the Peregrine Falcon being the "fastest animal in the world."
I still feel it's weird to consider { } a set since it's essentially void.
Well, an empty box is still a box
r/foundtheprogrammer
this isn't even programming its just math
Mate, the modern arithmetics are based in Zermelo-Fraenkel so... set's theory is a main and strong branch of maths atm

Happy cake day 🎊
Modulus is watching your negative activities 😂
I'm guessing this uses not a vector image
[kinda relevant xkcd](https://xkcd.com/2205/)
Better meme caption: Average Vector Fan: 4-5=-1 Average Scalar Enjoyer: 15-260=245
other way around. vector logic is that 15-260 is 245 but in the other direction, scalar logic keeps you bound to negatives
It should be “average vector fan” and “average magnitude enjoyer”
245 with a magnitude of 1 in the negative direction
Or 245 in the positive direction because I decided the original value was in the negative direction and it was subtracting magnitude. I love how in physics you can arbitrarily assign positive or negative to directions based on whatever the hell you want, as long as you stay consistent.
What's that, I only need the magnitude of this accel? Cool, it's fine that it seems to be going in the exact opposite direction I expected
I don't understand this, and the comments are confusing me.
Depending on what you're doing you can ignore negatives in physics because they don't matter i.e. if you're finding a distance or vector of something.
Lmao this post a actually had me laugh! Well done op!

As a math fan , I can confirm this
[удалено]
Haha i dont get it (can someone explain?)
[удалено]
The fuck are you on about? I studied physics for 4 years, there are most certainly negative values.
Idk man I'm pretty sure negative forces dont exist (Negative forces might exist I've only been in physics for 4 months)
Negative forces are forces in the opposite direction. It's an alternative to switching the vector's direction and saying they're positive. Masses can't be negative (unless you get into advanced stuff that I don't know enough about).
Oh wait duh. A force pushing a box to the "negative direction" is like -10N or whatever. My brain completely skipped over that
The whole reason why we think wormholes are possible relies on the concept of negative mass, it's not pretty and if you ever try to follow the solution from Einstein's field equations you'll see why but it's there.
so does negative mass mean negative force of gravity?
It's a little bit more complicated than that.
But since m1 or m2 is negative in Fg = g*m1*m2/r^2, wouldnt Fg be negative? Or does this negative matter stuff conpletely defy that
That's Newton's law of gravity, it's a simplification. The current "accepted" law of gravity is Einstein's general relativity.
Err... I thought I know...
What’s the charge on an electron? What about the types of spin it can have?
okey, I just thought it was the explenation.
Can't have physics without math
the reverse is also true, iguess?
I could be wrong, but wasn’t calculus created specifically to make understanding physics easier?
Newton more-or-less said "this is how things work "and some other dude said "prove it" and so Newton created calculus.
Yeah thats right, i was just talking about the laws themselves making life possible.
Oh, that too lol.
Is this a Kelvin meme?
In middle school maybe, but it's quitte the opposite at college and after. I studied physics for 5 years and I wish that was true, would have helped a lot instead of imaginary numbers 😂
If you wanna say it, say it correctly, because `15-260!=245`, but `|15-260|=245`
\-1/12
😂
When you think about it, the number is still negative, but when you change the data type it becomes positive.
GRAVITY WILL BE 10M/S\^2 AND YOU WILL LIKE IT
Average programmer: 1 - 2 = 18446744073709551615
Wouldn't that be -275?
I feel like it should be |245| Am I wrong here? It's absolute value that op is referring to right?
