i is my favorite imaginary number.
brainzeat
I don't care an iota about this
whiskyandsteel
Thank you all the maths people who came here to explain this. It made no sense, but I'm glad at least someone enjoys those crazy numbers
yetipc
imaginary numbers *solve* problems.

not really interesting tbh

Until you find out VAR is a thing, induction my friends is real and uses imaginary numbers to quantify it.

All numbers are imaginary

Hilbert spaces hold the math for the universe
ChocoladeMelkSnor
The fact that we do math is proof of that we make our own problems and cry.
DavidBrooker
To be fair, imaginary numbers aren't more imaginary than real numbers, and real numbers aren't more real than imaginary numbers. The 1/2
DavidBrooker
names only separate conventions both equally of our own construction (or discovery). 2/2
WanderingMess
Well i does have enough uses by electricians that they have given it it's own symbol, j, for when they need to use it.
thetrout77
"i" don't know what you're talking about...
lostinamapfactory
The root of many imaginary problems can start with being negative
holyicon
Some might even say, The Square Root...
lostinamapfactory
"i" would agree!
SavagePatchKids
All numbers are imaginary. Some numbers are just more imaginary than others.

You can accomplish the same thing as complex numbers via 2×2 square matrices, but it's gross and if you try to diagonalize them, you get i.
igollum42
What’s the square root of negative one? While you can’t create it or break it down, it does show up in math. So we have to give it a name.
GoodBrotherGrimm
42 is the most important number.

Tesseract09
Imaginary numbers just add an abstract dimension to represent things not expressible in a single linear dimension. Like how we need four
PballQhead
The complex number plane, with imaginary numbers, is just the Cartesian x-y plane in drag.

Dimensions to properly represent 3 dimensional rotations.

The detailed physics of electricity in conductors and inductors literally can't be explained without the use of imaginary numbers.
MrMineHeads
I mean they can, but they are made much easier by taking it to the s-domain.
deadandbloated
Hell, Maxwell wrote down the eponymous equations without even using vectors. It's convenient and elegant, but not necessary. [Physics PhD]

There are several treatments that explain electromagnetics without complex numbers.

What do they use instead?

i=L*dv/dt, v=C*di/dt
ChilledOutEntertainer
This is incorrect. Imaginary numbers are an extremely useful mathematical device, but nothing is directly explained by them.
ZAPZAPMOTHAFUCKA
This is incorrect. reactive power on AC circuits is mathematically explained with complex and imaginary numbers.
ChilledOutEntertainer
My point was that complex numbers don't correspond to any physical entity, as is the case with complex reactive power.
ZAPZAPMOTHAFUCKA
But reactive power IS a physical entity. AC induction motors literally don't work without it.
ChilledOutEntertainer
In retrospect, I agree with you. I can't say i doesn't exist but minus 1 does.

They also make hard things easier to deal with, they're basically the best numbers.
MrMineHeads
Circuit analysis would be so much harder without them
SeriousCloud
That's why we imagined them.
Rawrihazshotgun
also we didn't invent mathmatics
asm80dfa8sdfj
Didn't we though? Mathematics is our way of measuring things that happen. Mathematics is a scale. The numbers and ideas existed and we made
asm80dfa8sdfj
a way to figure it out. Running with the scale idea, humans weighed numbers before we invented scales. Scales just made it understandable.
Rawrihazshotgun
We may have made the symbols and instruments to study math, however the process of things happening is natural. Math was discovered.

My wife has been working on financial math all week for a class and it’s utterly confusing. They have their own special set of rules
texasfoodman
It’s infuriating that you always have to have a positive and a negative with no logic of why
kickmyballsrealhard
As a data analyst student, I feel this
DavidBrooker
I didn't come across anything like that in my econ classes - what sort of unique rules?
texasfoodman
So it’s to do with having 5 things, but only 3 of them can be a negative number, and not being sure which.

AccidentalPhallacy
It's always bothered me that we say imaginary numbers but there's really only one.
DavidBrooker
If you're saying there's "one" imaginary number because there's one imaginary unit and infinite multiples thereof, its entirely 1/2
DavidBrooker
equivalent to the idea that there's only one "real" number - one, the unit number - and infinite multiples thereof. 2/2
AccidentalPhallacy
How? If there were only 1 there can't be multiples of 1 because 1x1 is one.
AccidentalPhallacy
The set of imaginary numbers is just the set of real numbers times i, that's what I mean by there's really only one imaginary number.
DavidBrooker
That's exactly my point. You just claimed that the multiple of a number is not a number. That is incorrect.
innagaddavidababy
Imaginary, complex, and real are very unfortunate names that have no relation to the underlying concepts.

Don't forget surreal and Boolean numbers they look beautiful (i have synthesia and see numbers as colours)

Right? I'm an electrical engineer, and imaginary numbers are used to quantity real things in my field.
dabomber60
That sounds cool, can you elaborate at all? I’d love to hear how those numbers get used in the world!

Complex solution which contains a real part and a imaginary part.

Ya, you could rename the "Real/Imaginary/Complex" number systems as "Regular/Cheesy/Regular-with-Cheese" numbers and be no worse off.

"Natural" and "Transcendental" numbers are other poorly named sets. "Rational" and "Irrational" sort of make sense given "ratios."

I’m just a junior mathematician, so I can only cosine off on it.
Sepulchrave12
Math PhD here: the names are singularly unhelpful in understanding what is happening with them.
deadandbloated
Let's get real: the ideas are complex but the understanding is natural. It might feel imaginary, but mastery is transcendental. Quaternions.
Sepulchrave12
Strong finish, there!
Wiznatts
I always thought they made sense if you start from the reals. With no real solution to root(-1) imaginary isn't a super weird name.
Sepulchrave12
But why start from the reals? The reals are the completion of Q wrt |x-y|. And why call Q "rationals", when they're "ratios"?
OtherEdgeworth
Cause it has ratio in the name
Wiznatts
Also I don't think they're any worse named than negative numbers, more people are just familiar with them.
Wiznatts
Then complex numbers are more complicated since they make up a plane rather than a line.
Wiznatts
The ones I didn't like were counting and whole vs the integers lol. □
Sepulchrave12
The reals also form a plane. It's R^2. Any field forms any dimension vector space you want through Cartesian products.
