If you ask Rick Astley for a DVD of the movie “Up”, he will not give it to you because he is Never Gonna Give You Up. However by not giving you Up, even though you asked for it, he is letting you down. The Astley Paradox.

[@accountid9681]

This assumes that you would be legitimately distressed if you asked for a copy of the movie up from Rick Astley, and he did not give it to you, so by knowing about this paradox you have made it nearly impossible for you to act as it's inciting factor. (because any query would naturally be in jest, thus eliminating the emotional significance of the outcome) Thus we should maximize the number of people who know about the Astley paradox to prevent the universe from collapsing in on itself.

the "irresistable force" rephrasing of the "unstoppable force vs immovable object" paradox was made specifically for me because I thought I was so clever saying the unstoppable force would pass straight through the immovable object without moving it

[@darth_dan8886]

I've heard that answer a bit ago. Mind blown.

[@poudink5791]

How would it do that? By just phasing through it? Because if the unstoppable force had to make a hole or something, then it still had to move the immovable matter that was filling in that hole before it went through.

the actual problem is that 'unstoppable force' and 'immovable object' are fanciful statements. They're essentially infinite quantities. but also as long as entropy exists, by my understanding, nothing is unstoppable. And neither can anything be immovable! These are not rational terms. We can imagine them to exist, even write them down, but they don't, and can't. So woooo, they're paradoxical. so what.

I love that I know about the preface paradox now. Like without the context of, you know, how books get written and published, I could totally see how one could assume that "all errors in this book are my own" would mean "I checked all the errors in this book and confirmed that they were mine" (rather than what it actually means, which is "I fixed all the errors that I saw, so if any still remain, that's on me"), and then think "why would the author check all those errors but not fix them?" Wild. I love it.

[@globalincident694]

It's really intended to be a version of the lottery paradox but stated in slightly simpler terms. To put it a different way, if a particular page of a book has a 1% chance of containing an error, then it's rational to believe of each page that it is free from errors, but not rational to believe that every page is free of errors.

[@crumble2000]

The author would also need to check that everything in the book that is not from them is not an error

So if they had an editor that could potentially have made errors then it either is a different paradox, or just a white lie. Unless the editor highlighted every section they edited in which case the onus falls back on the author to verify that everything is correct.

@@lotarion it seems it would. But also, this is only if the rule was the only exception to the rule. there could be other rules that just don’t have exceptions, those being the exception to the rule of “all rules have exceptions”.

My favourite model for Schroedinger's cat is that, using a more general definition of "observe" as "have any interaction with", the cat is indeed an observer, and collapses the wavefunction, but now the state of cat + contraption is in a superposition. When we open the box, we ourselves enter a superposition relative to anyone who has not yet observed us, with our state being either "saw a dead cat" or "saw a cat that hadn't died yet" The only way to break an unobserved superposition is to interact with it and thus become entangled with it. Either the box is opaque or you're part of the box's universal wavefunction.

Interesting thing about the ship of Thesius is that it does technically have an answer. The "keel," that long piece on the underside of the ship which serves as the sort of backbone of the vessel, is the only part of a ship that is considered irreplaceable, as to do so would require you deconstruct the entire ship, and then reconstruct it onto the new keel and even then some things might have to be built differently. Thus, the ship of Thesius is the same boat, irregardless of how many parts or crew are replaced, until the moment the keel is replaced. Only then is it considered a different ship.

[@ovencake523]

but you've created a definition for a particular ship of Theseus, one where the rest of the boat must depend on the keel, in order to still be the ship of theseus what if someone comes along and cuts off the keel, but still leaves a single plank attached to the keel? Is the keel+plank the ship of Theseus?

[@otaku-chan4888]

tell me then- would _just_ the keel count as being the ship? if it doesn't, at what point do you stop adding new parts over the keel for it to 'become' a ship and hence be "the" ship? Until it can float? Until it can carry passengers? Until it "looks" like how the ship used to look? A core part of something's identity still can't define it.

[@dvillines26]

The actual question is 'what is a 'ship' as a discrete object? Understanding atomic theory, in the end everything is just a collection of atoms anyway, so the relative continuity of objects is an illusion to begin with. This is also true of people. Our sense of ourselves as consistently the same is a comfortable fiction. It's merely that the change is usually tiny, and we only consider an abrupt change to be meaningful. Like an entire plank of a ship being replaced, or like losing your sense of smell. But the entire notion of the ship or of you, yourself, is not what you think it is. It's not as discrete as you think, and what the Ship of Theseus actually exposes is something terrifying that people generally don't want to think about because it claws at the underlying (incorrect but useful) assumptions about reality we all share. It's best to maintain this fiction of discrete objects because it works well enough for ordinary life. The Ship of Theseus honestly isn't that different from a sports team. The players change, the coaches change, the uniforms change, but people call it the same team. Why? It's an agreed upon fiction. Ask yourself - what is your personal 'change threshold' where the change makes the current object too different from the original to be considered the same? And why do you use that threshold as opposed to being more or less strict about it?

ah yes, the unibody/lower receiver answer. we just decide one part that contains the inherent thingness of the thing

Shrodinger's Cat made way more sense to me when I realized that observe in the scientific sense used for quantum particles doesn’t mean the particles know if a human is looking at them and more refers to the fact that to observe things we often have to bounce light or something else off of it, and quantum particles are small enough that photons are significant.

A really nice example of “some guy getting confused” that you didn’t mention is the barbershop paradox-not the barber paradox, but instead a situation where three barbers work at a barbershop, and one of them only ever leaves when another specific barber leaves. If the ship is open, then the “paradox” is that one specific barber can never leave. Of course, the problem is that the law of implication doesn’t work that way. Yet somehow Victorian logicians were convinced there was a contradiction here and couldn’t figure it out.

4:58 A version of this story is the etymology behind the Chinese word for paradox, 矛盾, literally meaning "spear-shield". There was once this vendor who was selling spears, which he claimed could pierce any shield, and also shields, which he claimed could block any spear. Some smartass asked him what would happen if he set his own spear against his own shield. Interestingly, the Chinese word has expanded in meaning outside of just "paradox", and could mean any "difficult problem to solve", regardless of whether it contradicts itself or not.

Good memories, great video.

[@TacoDude314]

You missed the "paradox" part of the twin paradox. It's not just that relativity does counterintuitive things with time (like slowing down for faster moving objects). The paradox is that both twins see the other moving away from them and returning so why should either of them be younger? After all relativity is based on the idea that there is no absolute velocity of an object, just *relative* velocities between two objects. From Rocket Twin's (R) perspective why shouldn't Earth Twin (E) be younger because they flew away on Earth and returned to the space ship (similar to how R flew away on a rocket and returned to Earth). The solution is (essentially) that R actually accelerates while turning around but E doesn't. In the math of relativity, all inertial observers agree that R accelerated and E did not. I think this would instead be a math prank paradox because it incorrectly implies that there is a symmetry between the twins.

[@memyselfishness]

Additionally, when the travelling twin returns the deceleration needed to not instantly crash into the planet has the opposite relativistic time effects and the twins will be the same age. Though, that's only exactly true if they return to the same starting point.

My favorite paradox as a kid was the Pinocchio one “My nose will now grow” bc he lied so his nose grows, but then he told the truth and it shouldn’t have grown Idk why I liked that one so much I just do

[@MrCmon113]

Because it demonstrates something quite unintuitive: that the property "grows if Pinocchio lies" isn't possible. And such it is the case with many things that seem to make perfect sense, but upon closer inspection are nonsense. Such as the continuum question or the question whether there is something rather than noting.

[@qcubic]

I was thinking that Pinocchio's nose isn't a lie detector in the normal sense, but rather a "faith" detector, in the sense that Pinocchio's nose grows when he consciously (i.e. he is aware of the subject matter) misinforms someone about a topic. This new definition means that if Pinocchio is well informed about a topic, you ask a question about said topic, and his nose doesn't grow after answering, he is one of three things: - Objectively correct - Unaware of an error in his answer - Lying by omission (which is sometimes possible if the question presented is open-ended) Resolving the "omission" problem is as easy as presenting a closed-ended question, such as "Are you omitting the truth?" As for self-referential lying, I propose they are dependent on context at hand, if not completely subject to Pinocchio's belief in his answer.

There's a Mythbusters episode where they test the buttered toast thing, turns out if you drop the toast from up high with no bias toward either side, it'll fall butter-up due to the slight dome that buttering the toast gives the toast. If you knocked the toast off of a surface about the height of a table, however, the toast will do a flip and consistently land butter-down.

[@FinetalPies]

Yep, the weight of butter on toast is pretty negligible

[@joeg451]

The thing is, the butter moves the center of mass toward the butter side, but it doesn't change the aerodynamics of the toast. The most stable orientation for an object in freefall is the one which maximises drag (this fact falls into the "unintuitive facts about the universe" category of paradox). Butter makes one side smoother and less porous, so it would actually reduce drag on that side. Think about the pores of the non-buttered side like little parachutes and it makes sense.

Also it entirely depends on how you model the arrow.

Love this video and I find the classification of "paradox" not just good but quite useful and comprehensive. Also it is great to be introduced to more "paradoxes" in each cathegory. I do want to comment a bit on the math related ones as those are the ones I understand best, and first as a bit of a correction, "this sentence is false" doesn't prove that the system is inconsistent, but that either the system is inconsistent or incomplete, which is Godel's result and differs from "the set of all sets that don't contain themselves" which is a problem of set theory which can and is solved axiomatically. On the other hand, Zeno's paradox is a normal impossible question rather than a counterintuitive fact: the question is not on whether a line is made up of infinitely many points, but rather about how you can go through them in order, which leaves you with either Cantor's argument and you just can't, or the distance you're considering isn't actually infinitely subdivisible (minimum length). Zeno's argument wants to prove that movement is impossible, and indeed there's no way of mathematically arguing for an infinitesimal succession becoming finite in finite time (if needed, by applying the argument to time rather than distance). So maybe movement is impossible (philosophically, means that movement is an illusion), maybe nothing in the universe in infinitely subdivisible. On the Wollheim paradox, I do think there's value to it: you can't be both in favor of a law that wasn't approved being enacted and to respect the democratic system. However, I still consider it a "one guy getting confused", because if rephrased, the paradox becomes like this: 1) A person believes a law that wasn't yet voted on should be enacted in the future if it passes 2) The law doesn't pass 3) The person doesn't believe the law should be enacted after it didn't pass. The apparent contradiction is that the person in the past wanted the law to be enacted, but they don't anymore, even if they agree with the law. The statement "the person believes the law should be enacted" is therefore time-dependent. To finish this, my favorite math prank which I use to explain that square root is not as well-defined/well-behaved on the complex plane goes as follows: assume that we use sqrt(-a)=i x sqrt(a), with i x i=-1, which is actually fine. Then consider: sqrt(2)=sqrt(-1x-2)=sqrt(-1)xsqrt(-2)=i x sqrt(1) x i x sqrt(2) = i x i x sqrt(1x2) = -sqrt(2). Therefore sqrt(2) = 0. The trick is really hidden here: sqrt(axb)=sqrt(a)xsqrt(b) is not true for a and b not positive, real numbers. As a side note, this video gave me the idea of stating the monty hall problem as "behind two of the doors there are old, useless, boring cars, but behind the other one there's a COOL GOAT that you do want"

[@christianstonecipher1547]

I have to say your explanation for the monty hall problem made it so much more intuitive for me. Also I have to say my favorite example of the "unstoppable force meets immovable object paradox" has to be the myth of the Teumessian Fox and Laelaps from Greek mythology. In it the Teumessian fox is a fox that was destined to never be caught and Laelaps was a magical dog that never failed to catch what it was hunting. So as can be assumed Laelaps started hunting the Teumessian Fox thus causing a paradox. The end result was that when Zeus realized what was happening he just turned them both into stone.

[@RichardHarlos]

True. Also, many unconventional explanations that happen to be true get dismissed by the presumed implication from Occam's Razor (simpler is better, more likely to be true, etc.). Unfortunately, many of these dismissed ideas (that also happen to be true despite being unconventional) aren't vindicated until some time has passed and the person, people, population, group, etc., that initially dismissed the idea as a conspiracy theory -- well, they don't realize that their heuristic led to an incorrect conclusion. So, they continue to apply the heuristic, thinking that they must be correct and, typically, never realizing that they're putting too much confidence in a heuristic -- as if it was a rule rather than a rule of thumb. This perpetuates the practice of dismissing things simply because they're unconventional. Not a bad rule of thumb, but a terrible rule.

In short: many people who invoke the razor don't actually understand it correctly; their understanding is 'contaminated' by personal interests rather than by historical accuracy. _"Occam's razor is used to adjudicate between theories that have already passed "theoretical scrutiny" tests and are equally well-supported by evidence."_ When considered along with the previous insight, we see that *until* the theories under consideration have been scrutinized, none of them are to be preferred or rejected. It's only *after* such scrutiny occurs that Occam's razor finds relevance. To use it before qualification of each idea is to misuse it as a 'blanket dismissal'.

Well put Koala. I do get annoyed when people get this wrong. I do not mind too much when people just use the shorthand of this. But when they get it wrong, we get a lot of bad assumptions about the world. Turns out it is not simpler at all. Though again this has a lot to do with what people mean by simple. And so a more formal way of putting it like you did work better. One can view it from a pragmatic perspective too and use that as an argument for using Occam's razor. If you have two models that has the same explanatory power, then using the one that use the least amount of assumptions is preferable as it is easy to use a model with less assumption. And we are all lazy here. We are pragmatists, after all. ;) The video do put forth a good explanation for why one should actually see the world as real, even if you can not be 100% certain it is. (I mean, this sort of thinking that the world might just be an illusion is one that existed before Boltzmann's brain. Look up Descartes demon, but Plato allegory of the caves touches a little on this, as well as the concept of Maya in Hinduism. They explore it all from a different perspective. But they all question the notion of reality.) Again, a Pragmatist view on reality is that it does not really matter. Your actions seem to have a response when you act.

27:43 "Even though it looks like this infinite process keeps getting closer to the line we're trying to measure, the end result isn't really a line at all; it's a weird, infinitely zigzagy thing" (Funny, we actually just talked about this paradox/prank in my real analysis class!) This is actually a common misconception of the staircase paradox - the prank is even more devious than it appears! The limit of the zigzagy curves _really and truly is_ the straight diagonal line, in the exact same way that 0.9999.... = 1. The gap between the zigzag and the straight line gets smaller and smaller as the zigzags get closer and closer, and in the limit, they are equal. So - what's the flaw in the "proof" that sqrt(2)=2? (Especially considering Archimedes' famous approximation of π! He approximated the circumference of a circle by the perimeter of polygons with more-and-more sides. It's basically the same thing! We're approximating one curve with a series of other curves, such that the limit of the approximations is the true curve. So why does one set of approximations let us figure out the length, and the other doesn't? What on Earth is the difference? And in fact, that style of idea is sorta the key to calculus - we analyze something complicated with a sequence of better-and-better approximations. So fundamentally, this sort of thing often works. Why does the staircase break things?) Since I can't draw pictures in a youtube comment: let Dₙ refer to the curve with n zigzags. And let D be the perfectly straight diagonal line. We know these three facts are true: (a) You showed that the length of each Dₙ is 2; (b) I claim that the limit of the sequence of Dₙ's is D; and (c) we know that the length of D is sqrt(2). Summing it all up, here's the core of the prank: lim(Length(Dₙ)) = lim([2,2,2,2,...]) = 2 Length(lim(Dₙ)) = Length(D) = sqrt(2) (First line is: Take the length of each Dₙ. You get 2 each time. Now take the limit of that sequence of 2's; you get 2. Second line is: Take the limit of the sequence of Dₙ's. You get the straight diagonal. Now take the length. You get sqrt(2).) So, the prank is that the limit of the lengths doesn't necessarily equal the length of the limit: lim(Length(Dₙ)) ≠ Length(lim(Dₙ))! That's why the proof that sqrt(2)=2 is flawed: it implicitly assumed that the limit of the lengths equals the length of the limits. It might feel intuitive that that's always true (which is how you can slip it into a "proof" without people noticing the first time they see it) - but _a priori,_ there's no particular reason why it has to be the case. Sometimes it's true (eg Archimedean approximation), but sometimes it's false (eg the staircase)! So how can you tell in advance whether that hidden assumption - that lim(Length(Dₙ)) = Length(lim(Dₙ)) - is valid? How could you tell in advance that the Archimedean π approximation will work and the staircase one won't? When is it valid to swap "lim()" and "Length()"? Briefly, the answer is - it's not enough for the limit of the staircases to be the line; you need the the limit of the *derivatives* of the staircases to be the *derivative* of the line. Why? Well unfortunately explaining that in full detail requires some real analysis and is best done in person, and youtube comment boxes don't come with chalkboards. The closest I can get over the internet is a couple of interactive Desmos graphs I whipped up: www.desmos.com/calculator/5sufafga3w. The explanation continues there if you're curious! I don't rigorously prove anything but I try to communicate the visual picture explaining why the staircase doesn't work but the polygons do. (It'd make more sense if I could explain it with realtime two-way communication, but I tried to get across the key result anyway.)

[@emilyrln]

This is how I (a lay person who never went further into math than AP calculus) distinguish between the two approximations: When approximating a circle with polygons of an increasing number of sides, each step does get physically closer to the circle, so you're making progress toward reaching it. When approximating a diagonal line with right-angled zigzags, each step looks exactly the same if you zoom in, so you aren't making progress toward the diagonal line.

This was a lovely and very interesting experience, thank you for putting it all together friend

[@stevenglowacki8576]

@@emilyrln That doesn't help things, because you're proving the very fact that the diagonal line has the same length as the stepped line, so of course you aren't making progress! The real key to understanding here is that you can't always two different mathematical operations that are swappable in certain circumstances. The length of the limit is not always the limit of the length, even if it is most of the time. Part of real analysis is learning when you CAN swap two operations like this.

My answer to the heap paradox: A "heap" is not about the number of constituents, but their arrangement (piled on top of eachother in a disorderly manner). So, to make the heap of sand not a heap, you don't need to remove any sand at all. Spreading it out one grain thick over a large area would eliminate the heap too. But if you want to do it by removing grains, then it stops being a heap the moment there are not enough grains for them to pile up without deliberate arrangement.

I personally never considered the name of the paradox to be a statement of fact or an endorsement of one view over others. To me, its name could just as easily be about the idea of what that phrase means in the context of the paradox, if the Ship of Theseus is no longer around, or in the case where the old parts are made into a different ship, which one is the "original." The paradox is mainly because the ship fails certain criteria most people have unconsciously gathered about what makes something be the same object or an original, which means it's in a weird state of having some elements of it. Those being "serves the same function," "has largely remained the same materially," and "owned by the same people (when ownership changes hands, it's now the same item but someone else's)." Since it fails the second requirement outright, some have difficulty reconciling the fact it upholds most of the criteria except for the one many consider crucial to be considered the same item, while others straight up don't believe it's the same because they personally value the material component most when it comes to what an object is. One explanation I've heard from someone in the latter camp is that anyone on the ship would know it's a different vessel altogether, especially if they constructed one out of the old parts, as sailors can tell the differences between ships, even if they're the same make, because all wood has noticeably different qualities. So, to them, it's a ship of Theseus, but not the same one as before, despite having been used the same and the use never altered. For example, If you lose a spatula and buy the same one of the same brand, you don't then consider that the same spatula you had before. The paradox takes advantage of that idea, but instead makes it be a result of small alterations over time, which is more difficult to reject. TL;DR: The paradox just makes people think about some qualities they think are inherent and must be achieved for something to be the same object and some people value material over functionality or are just unable to give a confident answer since it contradicts what they knew earlier.

[@fulana_de_tal]

I'd argue that the fixed ship is still the same ship as the original, but none of them are the original ship. The fixed one changed too much to be considered the original ship, but it just changed over time, it wasn't replaced (just like adult me visibly isn't baby me, but both are the same person). The reassembled ship is made of the same materials as the original ship, but it isn't the same ship at all, it was made at a different time, under different circumstances (just like if someone were to sample my dna and make a clone of me that is currently a baby, that wouldn't be baby me, wouldn't be me at all, and while i'm also not baby me anymore, i'm still me)

[@jaydenholloway-sh8ti]

i love normal impossible questions because they can usually be chalked up to lack of definition (something you touched on in the paradox of the heap). just like how a “heap” of sand isn’t a definite quantity the way a “couple” or a “dozen” are, neither is a Ship (capitalized to show individuality, like Theseus’ Ship is different from a ship). a ship is a collection of matter organized into a form resembling and functioning like what we call a ship. in the same vein as the heap, the Ship is less of an object and more an idea. “Theseus’ Ship” is a sort of tag, a name we give to the matter that makes up the sailing vessel owned by Theseus. therefore, “the Ship of Theseus” refers to the matter Theseus owns and uses to sail across bodies of water, fitting the definition of a ship. by that logic, the “correct” answer to the Ship of Theseus question is that the new ship *is* the Ship of Theseus due to the fact that the term Ship of Theseus refers to the “tag” we give the matter rather than the matter itself. so much fun to think about

The propositions Everyone is unique There are traits everyone shares are not contradictory. Right? Because 'unique' doesn't have to imply that every aspect of someone is different from every other aspect of someone else. That couldn't possibly be true to begin with, because 'everyone' implicitly refers to humans, and all humans need to breathe, are born, die, are made up of cells containing DNA and mitochondria, consume things and drink water or water based liquids to replenish lost water from sweat and urination, etc. Those are commonalities generally agreed to be true. You could say 'everyone' also includes 'people' that don't share any of these traits, but first of all, those people don't exist as far as we know and are purely in the realm of conjecture, and second, people that read the initial statement are likely going to assume it refers to humans, and it's dishonest to claim afterwards that no, it can refer to other entities as well.
