8:33 the matrix is a 45° rotation matrix, so if you rotate the '×' by 45° you get a '+'
Thanks!
oh my fucking god that's what it is
i was so uncomfortable...

Wooow so smart! I didn't understand how apply the rotation... small brain
Damnnn, that's a good one oh my god!

everything is calculated
Because of maths
What clock?

Why am I even here, im a pretty shit math student and not even far enough to be able to understand 90% of this. I like it tho xd
Truer words were never said for me, by a stranger
I get about half of it. All of the analysis stuff is beyond me but I still find it funny somehow.
When you realize that papa flammy looked at his own memes in a video supported by his own shop lol

18:21 It looks counter-intuitive, but (A->B) V (B->A) is always true in Classical logic, hence the "T". :)
Edit: truth table.
ohhhhhh, damn! :D
I might be dumb, or misunderstanding what exactly classical logic is, but that can't possibly be true, right? If A and B are mutually exclusive, then (A->B) v (B->A) is false.
WARNING: I am no expert, and this is just my own understanding. Also long comment.
TL;DR: I think the "counter-intuitiveness" creeps in when we defined implication in Classical Logic as an operation (like addition, etc.), but it doesn't feel like that intuitively.
By "Classical Logic", I meant "Boolean philosophy" (proposition letters A,B,C,... are assigned TRUE or FALSE, but not both, bla bla bla). If you are familiar with truth tables, another thing you'll realize in (Propositional) Classical Logic is that in truth table semantics, logical connectives are interpreted as operations (on the set {False,True}).
Since you mentioned mutual exclusive, let's have a "set-theoretic" semantics (semi-rigorous):
Let U be the universal set. Then all propositional formulas correspond to subsets of U. Now, "A∨B" is "true" exactly when A∪B=U, "A∧B" true when A∩B=U, and "¬A" true when U\A=U or in short, A=∅. I hope you see the pattern.
Now what about "A→B"? Intuitively, we'll say that "A→B" is true when A⊆B. However, A⊆B doesn't "lead" to either U or ∅ or any other set ⊆U. This is B-A-D because compound formulas with implications like "(A∧(A→B))→A" will not make sense wrt interpretations for other connectives. This is where the "Boolean" interpretation of implication comes in: instead of A⊆B, we have "A→B" true when (U\A)∪B=U (and when translated back, it's "¬A∨B"). Silly suggestion, but convince yourself through examples that A⊆B and (U\A)∪B=U "say the same thing" as long as A,B⊆U.
Now that implication "is" the operation (U\A)∪B, establishing ((U\A)∪B)∪((U\B)∪A) = U is left as an exerc...
What I "feel" about it: honestly, it's still not intuitive to me. The thing is, usually when mathematicians deal with implication (and other connectives), they just use the "useful proof rules" offered (ex: deduction theorem, modus ponens/tollens, contra-positive, etc.). Then, all about semantics and proof rules are usually dealt by logic gang, logic gang, logic gan
If A and B is true, then "if A is true then B is true" is true. If A or B is false then one side of the OR statement is vacuously true. If they are both false than both sides are vacuously true.
@@mattermonkey5204 it's a Or statement, not a xOr
9:40 You know you are a mathematician when you laugh at a scatter plot
6:31
Or as Professor Gilbert Strang said, "jimaginary" 😂😎😎
9:22 Astronomy data in nutshell
Oh no, is this my future? I'm still in time to switch to particle physics!
Most data outside undergraduate laboratories. There's literally nothing wrong with that regression. Of course you would need to check for statistical significance...

It took me a while to realise that the clock is a joke. I was like, wait, thats not right 😂

he's actually pretty intelligent - watch some of his philosophy book reviews and explanations of math to his dog
Pretty much what I see him as
9:23 you think this is a joke until you read psychology/sociology journals
You could definitely outegral a function on a sphere and that would be finite. I think it would be interesting to take the set of all spaces where there is a function with an outegral(whatever that means) and that would have interesting properties.
I honestly don't know why am I enjoying this channel so much but please, keep doing what you do!
18:20 The T stands for True, as it is a tautology.
"High IQ meme" is about rotation. Matrix before the multiplication sign rotates it and you get a plus sign.
Dammmmmn
I still dont understand
@@Sasukej2004 The matrix shown at 8:40 represents a 45 degree counterclockwise rotation. If you rotate x by 45 degrees you get +, and + =
@@louishildebrand9080 cool but how is that a joke?
I don’t remember rotation matrix.
5:00 the noun "water" has the same cardinality as R. It is uncountable.
How come? That makes no sense. R has a cardinality of infinity. Water is just a word...
@@tcadityaa grammatically uncountable vs mathematically uncountable
@@li5516 He means that the word water is classified as an uncountable noun. Even if it can be 'counted' in some sense we don't use numbers alone to specify a quantity of it. Like rice.
12:47 And the cross product is when a train leaves from one person's house and another train leaves from the other person's house and they both meet in the park.
When they say I do not have a good humor, I'm going to show them dis. It's a gem. Papa knows🙈
Omg I made the meme at 12:50 like three years ago how did it get here hahaha glad you liked it
:D
smol world.
glad to see u reach 130k subs :DD
been subbed frm the day u had 20 to 30k n hve watched this channel grow up!!! gr8 wrk dude!! XDDDDDDD
Ayyy this is the first meme review I’ve seen as a subscriber lmao
6:00 that reaction lol
6:30 python uses j for complex numbers
also, the secret codes work :))))
i love how you have persona 3 music in the background
I thought I was the only who've heard it
I study medicine, I don't know how I ended here but I'm laughing af right now
0:53 the clock ticking in time with the clap.
*S A T I S F Y I N G*
the outegral is just the additive inverse to the integral because if you add them together you have the plane above and below y = 0 filled entirely such that they cancel out.
7:54
That's why we use scalar multiplication sign for multiplying in Norway.
3:20
Yet you used MATH in the title. Not maths. Outrageous!
If there’s anything that brings me a smile, it’s Jens’s smile in the thumbnail
One time in a physics lab, I had to fit polynomial curves to my data, and my best correlation was for an upside-down parabola lmao, ohhhh physics....
The uncomfortably cursed math memes is the same person as flammable maths............
Or is he *vsauce music plays*🤨🤨🤨🧐🧐🧐🤔🤔🤔🙄🙄🙄
Jens, Fehlau here
Yeahhh he kept referring to the page as himself
8:41 we're rotating the multiplication sign by pi/4 to get a plus sign. Very funny.
How can I hope to become a good mathematician when I can't even figure out the "high IQ memes"?
9:22 reminds me of a capillary zone electrophoresis I did, where my calibration series had an R^2 of 0.105 .... yeah ...
i have seriously not even started high school math and yet i am here even though i don't understand ANYTHING but you're so fucking entertaining
18:19 The 'T' is there because "if or only if" is a tautology.
A if B: B→A
A only if B: A→B
A if or only if B: (B→A) ∨ (A→B)
If you write out the truth table for that last expression, you'll see it's a tautology.
Last time I came this early she was mad at me.

If I ever write a multiplication symbol, I either use a dot, like I was taught (in america). Or I might write an asterisk '*' to distinguish it from a regular 'x'
Lol I was a high school student but I remember many people forgot to linearize their data before putting them into linreg and it was painful
Is that persona music i hear in the background?!?! Just found your channel and this is another reason to like it.
I have just realised that his clap and the ticking of the clock are in synced
number of memes I don't understand in this video: ITS OVER 9000!
Man are reddit's memes really cringy.
Yes
*Proof by contradiction*
Step 1: Assume reddit's memes are actually funny
Step 2: no they're not
q . e . d .
@@steventhijs6921 prof by induction:
1. The first meme on reddit is cringy
2. We assume all memes already posted on reddit are cringy.
Let m a meme newly posted on reddit
Since m is a repost of a previous reddit meme (by the fundamental axiom of reddit), m is cringy
Q.e.d.
In order for an outegral to be finite, you would need to specify boundary values for y as well.
Lmao this meme review was e🅱️ic indeed. Also I am already looking at the store, particularly at the phone cases, but I have a moto phone😢 ..maybe I'll check out the science toys or shirts tho
18:20 it's not a T, it's the opposite of the falsum, which is an upside down T. it represents a tautology.
0:52 clapping in sync with second-hand movement on clock
I feel the "jes" one so deeply. I study computer scienece and we have to choose a secondary-subject. I chose electrical engineering and was so confused what all the j was in the beginning xD
Now that's how you do a meme review 👍🔥
Whoa, you were clapping exactly in time with your Papa Flammy's Engineering C(l)ock, TM, at the beginning of the video
Loved your engineering clock!
The high IQ meme took me several minutes I have to admit. It was a pleasure though 😁
About the multiplication symbol in the US: we learn to use the dot for multiplication as soon as we reach basic pre-algebra.

The Joke of freezing water Had been invented by my physics teacher decades ago. The funny Experiment Here is: If you Put a Glass of water in a closed Environment and remove the water IT will Boile, If you Take a only a drop of water IT will Go directly from boiling to freezing.
papa please adopt dark mode... der Teufel sieht dein Licht! Verdunkeln!
the schrÖdinger meme is so hillarious :P
This is the stuff I wish I remembered and/or went back to school for. Seeing as one of my degrees is philosophy, I love the intersection of (some) forms of logic and (some) forms of math.
Anyone have any resources that are useful, but enjoyable that I could dabble in during my free time to refresh and enlighten myself with?
Just wait until every mathematicians on youtube decide to visit this
12:02 Me when i first saw vectors 😂
Does anyone here know in what topics can that generalised work equation with all those lagrangians and tensors at 4:07 be found?
Where is the playlist of these
I had an electric engineer friend in my first year and it blew my mind that they use j as the imaginary unit. Like... How can you confuse that with current? Smol brain
The transpose meme needs some snoring zzz's above the 'A'
The integral would actually be finite due to the parts above and beneath the x-axis having opposite sign and canceling each other. In that meme's case it would be equal to 0.
Not so fast! The same reasoning could be applied to the integral on the left but we all know that the integral over the sine function is indefinite.
Another tought: Would't the outegral of a given function just equal the integral over the inverse function? Because x and y axis are simply flipped around...
I'm not sure this logic can be applied for infinite areas. After all, the integral of 1/x from -a to a is divergent, despite the fact one could argue the negative area "cancels" the positive area
I don't know if it's true formally. I agree my reasoning sounds a little iffy, but I think it sounds convincing given that the function is even as opposed to for instance 1/x.
@@InToTheNetherMc I still don't see it. I mean, if you just look at the normal integral of cosx from -∞ to ∞, it also diverges
@@gamerdio2503 Yeah, that makes sense. This logic does indeed seem incomplete.
There cant be a finite outegral, since a function can be either 0, greater than 0 or smaller than 0 in an arbitrarily small interval. The outegral in this interval has to be infinite sine if the function is 0 the outegral will be infinite, if the function is greater than 0 the outegral will be infinite since for y
18:29 I think the point is that "If AND only if" is A=>B AND B=>A, so "If OR only if" would be A=>B OR B=>A, which is true in all cases, because A=>B is only false when A=T and B=F and B=>A is only false when A=F and B=T
Hey it’s the guy that was in the video about teachers with the guy that was in the video with Flammable Math!
8:16 Yep, I do that kind of x all the time. My grade 9 math teacher did it, and I liked how she wrote it, so I copied it. Ever since then I've written it like that.
12:06
Ah, I get it, cause vector notation with coordinates x1, x2.
but there is a scalar on the right and a vector on the left, could you elaborate what you "get"?
The broken coffee cup is now topologically equivalent to a disc 😔
In my calc class taught by engineer professor, he usedto write his X's weird....
NOW I KNOW WHY!!!!!!!!!!!!!!!!!!!!!!!
OMG YES FINALLY!!! Thank you so much!!
Edit: I think an outagral can either be infinity or zero
ye :)
12:06 seen that one before, hasnt gotten better
I took the AP calc AB exam today and these memes are so much funnier right after taking an exam
10:42 At my school some people are so afraid of the "engrineering" notation j=imaginary unit, that they use dotless i instead. Little do they know it's just primitive function of i.
For me, a math i without a dot is literally just a c lmao
i needed to reach the Schrodinger meme to laugh loud
Took me a while to get why you get the imaginary unit when you differentiate Yoda with respect to t...
If there exists a outgral that is finite? For continuous not, cos these functions are limited under intervals... well assuming that you are just worried about areas and not the function values sign. The problem about giving positive sign for positive values of x and negative sign for negatives is that you need to thind a what that this sums makes sense to calculate.
WAIT at 18:02 it took me a few seconds to realize the test tube liquid is green. At first I thought it was invisible because I have never seen the template before...

Hey flammy, when you will review your collection. I see you re a man of culture
The "a water" part is a meme itself based on adding "a"s around to make a text sound italian
Integrate over a torus or a compact space with finite measure
Are you an electrical engineer ?
J am
Maybe an outegral in some non-euclidian space would be finite, if you don't allow for overlap.
He doesn't realize that the identity theft one stated what the meme creator did as well
Sad.
"Assume the Multiverse, ..."
I hate to think about time as a vector. It's not even constant everywhere.

(Laughs in broken logic)
as a high schooler who doesn't know what integrating, or half of the symbols in this video means its still kinda funny
Got reccomended to me today, i understood almost nothing
:D
The clock hurts me. Especially the 12 being 12pi/e
7:28, I divided it with 3 and it gave me a whole number: 14023. How is 42069 a primenumber?
Yeah, kinda ruins the meme.
its obviously devisable by 3, you can check by doing 4+2+0+6+9=21 -> 21 is devisible by 3 so is 42069. That is the joke here.
