My FIRST Ever Math Meme Review :0

[@DaFrancc]

29:30 So these guys are suggesting that math is racist based on statistics. Statistics is a field of mathematics, therefore they used racist and unethical means to reach this conclusion

[@vandel_]

Watching this video is way better than going on reddit and scrolling. It's way easier to listen to what Flammable Maths says than opening a new tab and searching stuff every time you don't understand something.

7:05 - Those are the fundamental operators. Addition, multiplication, exponentiation, tetration, pentation, hexation, etc. And in the case of 2{operator}2 it's always equal to 4. 27:25 - The graph is doing what drunk people do. Start doing something that they won't complete because they'll feel tired before they can even get going, they get hungry out of nowhere and they find others more attractive than usually.

He was very careful, it was very intentional.

[@denizgoksu9868]

28:10 If 1 and 2 are considered under their usual definition (1={ø} and 2={ø,{ø}} where ø is the empty set), then it is manifest that the set {1,2} contains two distinct elements, while {1} contains just one element, disallowing any surjections from {1} to {1,2}; this is no problem under constructivism. I believe the OP confused this with the statement-or a similar statement-that under constructivism, it is not provable that the set {a,b} is finite-let alone countable-for any two arbitrary sets a,b. This is because the proposition entails by a routine calculation that any pair of sets are either equal or not equal, which can be shown to be logically equivalent to the excluded middle

[@98danielray]

for the rearranging it has to be conditionally convergent. divergent series taking those values happen because they are misapplying properties (like the existence of an additive inverse), not because they go to those values.

[@martinshoosterman]

7:23 is a good meme. I think their notation is wrong though, it should be 2[n]2 not 2{n}2 But Bassically 2+2 = 2[1]2 2 × 2 = 2[2]2 2^2 = 2[3]2 It's a generalized notation for repeating the previous operation. For 2 though it's the same for any n.

[@dan-us6nk]

2 is mind blowing

[@mumujibirb]

Unless you use BEAF, which chooses {}.

[@louisrobitaille5810]

They're just operations and hyperoperations. In order, going anticlockwise: addition, multiplication, exponentiation, tetration, pentation, hexation. Afaik, exponentiation is noted as x[1]y, tetration as x[2]y, and so on though 🤔.

@@PapaFlammy69 should have said to your 7th grade class that "math is arbitrary and typically things are defined in a certain way because they are useful when defined that way. You could just as easily define it another way, but it might not work out logically with other parts of math, or simply be useless"

[@SunnyKimDev]

23:44 While this reasoning takes out Brinner, Dinfast is still valid because two given meals of a day can be different but congruent (modulo one day). There can be a meal *after* dinner, *before* breakfast. (which would typically be eaten around 2~3AM)

[@veliulvinen]

Also, if someone, potentially a hungover student, oversleeps and wakes up at dinnertime, that would be their breakfast i.e. brinner.

[@rautakoura5663]

Not sure if someone commented this already, but the series in 3:50 converges and all the operations make sense in the field of 2-adic numbers, so the end result should also be valid, and indeed S = -1 in 2-adics. This also explains why your factoring out 4 leads to the same (correct) result.

[@liweicai2796]

Or simply apply the same logic for 1+2+3+...=-1/12. 1/(1-z) is the analytic continuation of 1+z+z^2+... over C and it indeed equals to -1 when z=2.

[@98danielray]

also, the result he was referring to is for conditionally convergent series

[@AlcyonEldara]

Yep. And if your topology arises from an absolute value on Q, this serie is either divergent or converges to -1.

[@PunnamarajVinayakTejas]

@@liweicai2796 Does that agree with the epsilon-N definition of the sum of an infinite series though? Methinks not. There's that caveat that people tend to forget.

[@eig5203]

7:11 That notation is the beginning of BEAF used in googology. The way it works is: a*b = a+a+..+a with b 'a's a^b = a*a*..*a with b 'a's a{4}b = a^a^..^a with b 'a's a{5}b = a{4}a{4}..{4}a with b 'a's in general a{b+1}c = a{b}a{b}..{b}a with c 'a's It is just another way of representing hyperoperators/knuth's up arrows (but the BEAF notation goes further beyond just hyperoperators).

[@orisphera]

5:20 I know 4 meanings of x=x+1 in normal programming languages: - In Pacsal, this is a comparison. It is always false for integer types of x, but it is true for large enough real x's - In many languages, including Python, this is an assignment. It can be thought of as “x after this = x before this + 1”. However, it usually can be also written as “x += 1” and, in some languages, “++x” - In Python, if passed to a function, it is a keyword argument. If the function has an argument called x, it means “x inside the function = x in the scope where it is called from + 1” - Also in Python, if specified as an argument for a function when defining it, it is a default argument, meaning “x in this function if not given = x in the scope where it is defined + 1”. The addition is done when defining the function

[@kensmusic1134]

3:50 yes, the series is not absolutely convergent, therefore not every rearrangement of the series converges to the same value

[@Kurushimi1729]

No arrangement of this series converges at all

[@kensmusic1134]

​@@Kurushimi1729 Yeah, that's true. if the series over (an) doesn't converge, then |(an)| doesn't either. But if (an) converged, |(an)| would need to converge, so that every rearrangement had the same limit. Absolute convergence was just the term he was looking for.

[@Gretchaninov]

The value of -1 does make sense in some contexts, like the continuation of y = 1/(1-x). It's not a completely invalid result, it just depends on what you mean.

[@ДмитроПрищепа-д3я]

@@Gretchaninov it has an even deeper meaning if one would apply exponential regularization or something like that.

[@Quasarbooster]

7:15 Those are the hyperoperators (albeit a weird notation for them). They all equal 4.

[@rubixtheslime]

I think if they used knuth up arrows it would've made more sense, also probably make it so that you don't naturally read ellipsis second

[@Quasarbooster]

@@rubixtheslime I agree. Or they could've just used 4 guys for 2+2, 2*2, 2(n arrows)2 (for all n>=1), and ellipses. That way it wouldn't stop at hexation.

[@riccardoredigolo7802]

At 3:56 I think you are referring to Riemann's Theorem for simply convergent (convergent but not absolutely convergent) series. To get that result you need the general term of the series to go to 0 tho. In that way you are able to rearrange the terms of the series to get whatever number you want. So that series would not work even if you were to consider Sum_{n in N} (-1)^n 2^n.o

Yes, exactly! :)

[@cosmicvoidtree]

3:33 for this one, it actually doesn’t matter where you start factoring, that method will always be -1. As a quick sketch, you start with S=1+2+4+8+…, then wherever you start factoring, the terms before will be a sum of n-1 powers of two which is trivially 2^n-1 (the proof of which is left as an exercise to the reader) then you factor out a 2^n from the remaining terms. Using these, they yield S=2^n-1+S*2^n. This can be rearranged, to S(2^n-1)=-(2^n-1), which reduces to S=-1 for any factor point. Alternatively, one of 3blue1brown’s oldest videos actually covers this sum: kzbin.info/www/bejne/jnenfmSfpZp7mrc

[@dudono1744]

fun fact: x=x+1 would also upset computer scientists, they use x++

[@McNether]

02:49 following this logic you also cant have a disk in real life because there are also dimensions in which a disk got no expansion. In reallife we can only cut out a cylinder (at least approximatly). 03:46 When a series is not absolutely convergent but convergent you can get every real number as a limit by rearranging the summands. But i feel like for this sum there should be some other values we can reach by doing simmilar stuff. 22:52 I had to like there

[@stopwatcher8930]

Would you call a cd disk a cd cylinder then?

[@emilio2864]

Probably not so crucial for your content, but I think I heard a famous paradox that helps explain the cardinality of N, Z and Q, it has something to do with an hotel with infinite rooms. Maybe you could use it to help your students understand. Anyway love your content Papa Flammy, keep it up!😁
