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.

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.

My favorite "one guy getting confused" paradox is the cheese paradox, similar to the temperature paradox: Cheese has holes The more cheese you have, the more holes you have The more holes you have, the less cheese you have Therefore the more cheese you have, the less cheese you have. It's pretty obvious what the problem is, like you don't even have to rephrase it, but I still like it for the split second before you realize it doesn't make sense

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
@accountid9681 Жыл бұрын
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.

Unfortunately did he explain how? I mean I heard him give a couple ideas but they did seem kinda silly plus I'm pretty sure the cat would land On their feet. However if you were to butter 4 small pieces of bread then butter side up stick the bread to that bottom of the cats feet; Then even if you were to drop the cat, from counter height feet down, I don't think the cat would want to land on his feet. I think the cat would try and throw itself sideways it would not want to land on that bread butter. I think that is the only way they might not land on their feet.

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.

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.

@@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”. Rules like all numbers are equal to itself that are just facts of reality. This doesn’t break the rule, because exceptions don’t break rules. In this case, a rule not having an exception further proves its own point.

I love when Douglas Adams encountered a proper Ship of Theseus (or rather, Building of Shinto) where he was in Japan and came across a Shinto Shrine that had been around for centuries but looked brand new, and when he asked a custodian about this the custodian revealed that the building had burned down multiple times over the years but had always been rebuilt to the same designs. When Douglas asked if it was still the same building then if it's been rebuilt over the years the custodian said that "It's always been the same building". Douglas concluded that one of them was missing the point but was willing to concede it was him.

similar to your example is the immutable fact that the ship of theseus ceased to be when the mast was replaced, as in that moment by law it required an inspection with relevant taxes paid to be a legally seaworthy vessel. the ship of theseus obviously cannot be a vessel which is not seaworthy: removing the mast irrevocably introduces a hole into the timelime before which the original may or may not exist, during and after which it does exist as it is not the ship of theseus (theseus' must always be seaworthy or it isn't his).

Well, this is also the og ship of Theseus According to Plutarch, ship of Theseus was preserved in Athens and was on display up to some point. And Athenians of course were replacing parts that were rotting away. Like, according to the sources it is not just thought experiment, but a thing that happened (of course the question is that is Plutarch record about it is true given he lived about 300 years after the ship got lost/destroyed/not there, according to him, and if it is true what is original origin of the ship given that Theseus was pretty much just a legendary figure)

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.

In this case the easiest way to show it is to already know that the 1/n^2 series converges, and 2^-n terms approach 0 way faster than 1/n^2 terms due to exponentials dominating polynomials, so the series converges way faster than the 1/n^2 series.

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.

Though it's relatively easy to answer- there is a fault in our language, and a bit of misunderstanding. Observation at a quantum level is very, very intimate. It's an action the observer takes. At the quantum lev3l, you have to get out a metaphorical sharp stick and metaphorically poke the particle in question and listen for its exclamation of "ouch!". The act of shining a light on something actively interacts with it, to extract information. The act of shining that light also fundamentally changes the something's properties, collapsing its superposition (if any). The machine doing the measurements is an observer, in this case.

35:49 They're basically talking about two different kinds of desires. "Wants" and "beliefs". A "want" is something that would make you happy if it happened, but that you wouldn't necessarily force to happen. The guy in this paradox WANTS their policy to be enacted; they might be happy if some corruption in the political system occurred and their policy was put into place, but they wouldn't choose to make that happen. A "belief" is something you think should happen. You would force it to happen, even if you don't "want" it to. This guy believes that whatever policy is democratically chosen, regardless of how much they like it, should be enacted. It's what they'd choose if presented with that choice. A belief is formed from a logic equivalent (such as justice or personal morals) whereas a want is purely the realm of emotions. So, basically, it's a paradox because someone's wants and beliefs are in conflict. The paradox is essentially stating "emotions aren't logical", which, like, yeah.

Most people oversimplify Occam's Razor. It doesn't say that the best explanation isn the simplest one, but that an explanation with fewer assumptions is preferred to one that has more assumptions if both have the same explanatory power.

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'. That's not how William himself used it, and when it's used that way today, it's being invoked erroneously.

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. And those responses seem to be consistent. So even if it is just a dream (illusion, whatever) there seem to be rules in that dream world. And so act accordantly.

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.)

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.

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.

Philosophical paradoxes like the Ship of Theseus are fun, because the "answer" to the question is "to what end are we determining what is defined as the ship of theseus" because on a pure thought-experiment level there isn't a single right answer, but if we are asking "which ship belonged to Theseus as per his last will passing it on to his children" then obviously we're thinking the Functioning Ship And Crew and arguing otherwise is bad faith, and if we're asking "what counts as the ship of theseus because we're a museum trying to display the ship" well then you mean both if you have both, but if you only have the repaired version it's still logically the ship of theseus. The design itself is overall kept in the repaired version, as the question normally doesn't posit "well what if during repairs Theseus chose to redesign some of pieces such that it technically counts as a different kind of ship" but if you've managed to get all the original pieces and can arrange them in the original shape then that has equal historical value as to prove the refurbished one is the real deal as well! And if you're asking "What's the original ship of theseus, I'm trying to learn all I can about boats and I heard that theseus' ship was the most long-lasting of all ships!" well you probably still want both, but it's now the original wood that may matter more, because if it lasted so well for so long that one only needed to replace a single piece at a time, the kind of wood the original was made of may be the focus of that durability, and if you can just find out what wood it was originally made of...! The paradox becomes one of philosophy, because all of these ARE right answers, and some of the interesting things to take away from it are "when considering the answer to a question, you most certainly should be considering *why* that answer is needed", as well as "if something similar happens in real life, how do you recognize it's happened" see the Alt-Right Playbook on the Ship of Theseus and how people can couch lies in truth.

It's a fun gateway to ontological conversations for me. Any object is only that object when we prescribe the label, and no natural law makes any given thing the thing we call it. Like the ship of Theseus, any object becomes that object when we say it is. My favorite demonstration of that is metals. In space stations, metals that will be exposed to the vacuum often need coatings. Metals have this fun property where they just ARE one solid piece when they touch. So you make a door on Earth, close it tight, shoot it to space, and it welds with whatever wall it was touching. The atoms in the metal don't know where the door starts and ends, so there is no start or end. The only reason this doesn't happen all the time on Earth is because that metal reacts with the air and forms a film.

@@Eclipsed_Archon Wait, really? Atmospheric oxidation is all that's preventing metals from self-welding on contact? Seems wrong to me, but I'm very interested-- like, it seems vaguely plausible due to the nature of metallic bonds, but I don't know much about it, and I wonder why this property isn't widely exploited in industry. Like, I know there is a phenomena with the gauge blocks used to calibrate machine tools, they call it 'wringing' and it lacks a robust mathematical model, but is generally assumed to be due to some combination of intermolecular forces and surface tension of residual fluids between the blocks. Aha! I just found the wikipedia entry for 'cold welding' and it seems like you're even more correct than you put forward-- apparently it isn't exclusively the electron structure of metallic solids that enables 'vacuum welding' -- it's observed in other crystalline solids as well, even moon dust!

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.

a heap is a structure wherein the root node has multiple children. these children may or may not have children or a child. the root and children are a or are many instantiations of a class. the heap is arranged accordingly. obviously it follows that the heap begins when it is instantiated (say, between zero and infinitely many grains of sand, inclusive) and ceases to be at cleanup (specifically zero non-grains of un/deallocated nothing), regardless of its size interim. qed the paradox is solved thank me later philisophers need not reply

not a real paradox. it's a natural language slip. "Unique' is used in two ways, implicitly. People are unique in that no two people are exactly alike, BUT they share the commonality of uniqueness as a shared quality everyone has. 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.

Is a sunken ship still a ship? How many pieces can you remove from the ship before it stops being a ship? So I guess most of our everyday words, e.g., only defined by aggregation or by usage, have a fuzzy meaning.

Range, Berrabah and Ewen released the group's seventh studio album, Sweet 7 (2010), after which they signed to RCA Records, before taking an indefinite hiatus in 2011. That year, the original lineup reformed as Mutya Keisha Siobhan and released the single "Flatline". The trio regained the name Sugababes in 2019, and recorded a rendition of the song "Flowers" with DJ Spoony.'

9:30 - It depends what you mean when you say the original ship. This gets into why we have names or categories for things in the first place, and the answer to that is: it depends why you need them. If you're organising the shipyard or ship logistics, the one with replaced parts is the original, because it is the object you've kept track of the entire time, whereas the newly assembled ship (even if from the original parts) is a new entity as far as you're concerned. If you're one of the old crew and have attributed sentimental value, then the maybe the original parts are what make it the original ship. Asking someone who has no involvement with the ship is like asking someone where to put a chair in your new apartment, without giving any information about its layout. There actually is no correct answer... for them.

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.

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)

In Spanish, for example, we have "ser" meaning to be something, and "estar" meaning to be doing something ( and a couple more things) this means, the statement would not make sense in Spanish, since we would say "la temperatura ES 90 grados" but the second one would be "la temperatura ESTÁ subiendo".

For example, “if 3+5=0, then 4 is an odd number” is actually a true statement, though it certainly doesn’t feel like one.

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.

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?

The Irresistible Force paradox has been documented in a chinese written poem written in 200BC which consists of a lance and a shield and the explanation that both can't exist at the same time. Because of this poem the kanji symbols for lance (矛) and shield (盾) together (矛盾) mean contradiction to the present day in both Chinese and Japanese writing (there are other possible spellings of contradiction which do not use the symbols for lance and shield). So if you try to confuse a Chinese person with the liar paradox he might know the origin of 矛盾 and deduct that the answer is that the underlying logic of the liar paradox is flawed and from falsehood follows anything (Ex falso quodlibet aka Principle of explosion).

But irl no object is locked to only ever have 0 acceleration, so the question isn't a paradox but a question of what will win, the stationary and high inertia object or the moving and high inertia object like a run away semi truck vs a concrete wall.

My preferred solution to the Ship of Theseus question is to follow the continuity of the ship. Just like how we consider adults to be the same person as the one in their own baby photos, even if not a single atom in their body has been retained from the moment of that picture. But if someone were to magically assemble all those atoms back into the same shape, that baby wouldn’t be the same person, it would be a perfect replica of what that person once was. And a replica is not the original. If, at any point, the ship ceases to be a ship (for example, if it was disassembled, then reassembled), continuity breaks and it would not be the same ship, but a recreation/reconstruction/replica.

There was an error in the twin paradox. The real confusion with the twin paradox is that each twin sees the other twin moving away from themselves at the same speed, so when they reconvene, which twin is meant to be older? The answer is that for the twins to reconvene, at least one of them must turn around. To turn around they have to accelerate. It is the acceleration which causes the twin to experience less time, so the twin that accelerated will be younger.

@@Spock149 TL;DR talking about "how observers see eahother" is very tricky in relativity because observers are local beings. This is safe to do when talking about constant speed observers because transformations between the frames of these observers is a symmetry of flat spacetime, but its more complicated for accelerating observers, and we should avoid doing it if we can. The reason the twin paradox is solved is because the accelerating twin took a detour through space to get to the same point in spacetime that the stationary twin moved straight towards. The acceleration is then the curvature of this detour. This is a very reasonable and common confusion about special relativity. What you're talking about is going into the natural frame of reference, or coordinate system, of the accelerating twin. In that coordinate system, the other twin will be accelerating, so we should get the same paradox. This doesn't work for a couple reasons. Firstly, the natural coordinate system for the accelerating twin is actually curved, meaning spacetime separations aren't measured as -c^2t^2 + x^2, as is the case for the stationary twin. In the natural coordinate system of a constantly accelerating observer, separations are some complicated integral. This is quite technical, but the point is that the accelerating twin is naturally working in a curved coordinate system, so the passage of time for observers accelerating relative to them are distorted. Secondly, "natural coordinate systems" (and now I will invalidate my previous point) for particular observers don't actually make any sense! Everyone is confined to a local region of the spacetime, so how can a coordinate system, which covers the entire spacetime, capture how a single observer sees the whole spacetime, if that observer can't ever see the whole spacetime at once? The answer is that it can't! It turns out that "natural coordinate systems" are only useful to understand the physics in simple cases like for constant speed frames, or if you have many observers all recording the spacetime at the same time, and comparing notes at some point in the distant future. So how does the acceleration solve the twin paradox? This is easy to see on a spacetime diagram. The stationary twin goes straightforward in time from point A to point B. But the accelerating twin takes a detour through space. As I mentioned before, in the natural coordinate system of the stationary twin, distances are measured as -c^2t^2 + x^2. If this were just pythagoras, then the straightest path from point A to point B would be the shortest. But, because of that minus sign, the straightest path is actually the longest. The length of the path of the observer through spacetime is the proper time they experience, so the accelerated twin takes is aged less! In a sense, you are right though. Saying the twin aged less because they accelerated is perhaps misleading. It would be like saying that an L shaped path is longer than a straight path because of the angle. Also, if you want to understand this stuff better, minutephysics has a good video series on SR.

It generally can only complete 1/2 spin from the average table height before it lands.

I'm really confused why anyone would say 99 lbs, but I'm even more confused why anyone would think they weigh 50 lbs. Assuming the water that dries is completely converted to solid matter (none escapes), then the final weight would still be the same. The only issue is some density (and volume) change would occur, not a mass change. If some water evaporated away, then the final weight would be the initial total minus the evaporated water. That is, the case where the total mass has declined such that the final RATIO of water to solid is 98:2 (or 49:1) where the initial mix was 99:1. In this case, you are actually saying that A LOT (a somewhat absurd amount, actually) of water has evaporated, but you still cannot reach the final conclusion without knowing what water weight is vs solid weight. That is: In any case, to get an answer, we'd need at least a rough ratio of the water weight vs the solid weight.

A remark regarding Xeno's Paradox: the ancient Greeks didn't employ the same mathematics as we did today. They didn't have algebra - they were a lot more geometrically minded. The only numbers they could really work with were numbers derived from using a straight edge and protractor. You may have heard the expression 'squaring the circle' to mean attempting an impossible task - it refers to trying to generate a square with the same area as a circle. This was impossible for the Greeks because pi is not a constructable number, but algebraically we can do it today. The Xeno paradox stems from the Greeks assuming that the sum of an infinite series must also be infinite (because you can imagine adding more and more to a straight line will cause it to increase forever). Algebraically we can demonstrate this not to be the case: deapite being able to decompose a trajectory into infinitely many segments, we know the time taken to traverse it is finite.

I think two of the "guy gets confused" paradoxes are legitimate paradoxes, at least as legitimate as the 'math pranks', but they deal with formal semantics, which is intuitive to anyone who speaks a language but is difficult to explain. The white horse paradox explains why every (one place) predicate needs an extension (and that an extension is a set), and the temperature paradox explains why the equivalency relation only holds between two referring expressions. When the copula is used between lexical items that are not referring expressions (like ninety or rising), the relation it is predicating is not equivalency. Again, both of these things are intuitive to a speaker of a natural language, but they are useful thought experiments in explaining semantic concepts. Just like how the math pranks are useful in explaining mathematical concepts. It is conceivable for a student to ask the question "why do predicates need extensions?" and then getting the white horse 'paradox' as an answer, just like how it is conceivable for a student to ask "why can't we divide by zero?", and getting the algebraic math prank as an answer. the elevator one though that one's rough

Another "paradox" that always bugged me was: "If it was zero degrees yesterday, and it's twice as cold today, then what's the temperature?" This is one where the writer just got confused about the words, because "cold" is subjective relative to what you consider comfortable. The assumption is that twice anything zero is still zero, but since the question doesn't specify whether we're talking about Fahrenheit, Celsius or Kelvin, calling it "zero degrees" is arbitrary.

The thing about this one is that it's incorrect to assume doubling zero is the same as doubling "cold". After all, temperature is (in layman's terms) a measurement of heat. A temperature of zero is certainly cold, but zero isn't the measure of *how* cold it is, and therefore is not the data which should be doubled to determine the current temperature.

Actually, toast does not fall butter side up because it's heavier, it falls down because when you push it off the table (more than half way), it gains rotational velocity and slides away (because the part off the table falls and the part on the table get brought up due to the pivot point on the edge of the table) and the toast spins while falling ! Then, most table are just the right height to allow a half (I think) rotation of the object before touching the floor, so the top side hits the floor. This basically works with any object that is the shape of toast, and is not impacted by the buttered side being heavier (besides, the butter would just shift the center of gravity of the toast, effectively making a thicker toast since the density of butter is close to the one of bread) Also, (and this accounts for the times you drop a piece of toast while standing up), there is some form of suviviorship bias, you are more likely to remember the times the toast fell butter side down. But cats really can contort their body to land on their feet, the way they change their angular position without changing their angular momentum is really cool

For the "unstoppable force" meets an "immovable object" paradox, there is an answer. It is that both objects pass through each other. That way the immovable object doesn't "move" and the unstoppable object doesn't "stop". Think about it, by definition "unstoppable" means that once moved, that object's velocity cannot be changed. Therefore anything movable can be pushed at the same velocity as the unstoppable object (without slowing it down). But if there is an object is immovable, that means that its velocity cannot be changed whatsoever at the time of its conception. Therefore the only logical conclusion for both objects meeting is that both objects pass through each other without changing each other's velocity (not PHYSICALLY possible, considering an unstoppable force even existing literally breaks the first law of thermodynamics, but logically in this context it is). The blade and shield example is a paradox though, as a shield that can "block any blade" by definition needs to stop the blade AND not be cut so it doesn't go through the shield. The stopping the blade part is what makes it a logical contradiction, as it gets rid of the "moving through each other" possibility.

@@pyropulseIXXI It is a solution in formal logic, just not one that immediately makes sense intuitively. Written out formally, it would be equivalent to p => q p => not q where p is "Bill and Ted will fight" and q is "Bill will win the fight". Combining these statements shows that they are logically equivalent to "not p", which you can show pretty easily with a truth table, or just by using a few simple axioms. Therefore, both of these statements being true _does_ logically imply that Bill and Ted will never fight. Obviously in the real world, the actual conclusion would be that these statements can't both be true, because in real life it would be absurd for it to be _impossible_ for 2 people to ever get into a fight. That doesn't make this line of reasoning incorrect though, we are simply adding in _another_ premise that wasn't present in the original problem. It's important to remember that, in formal mathematical logic, you don't add in "common sense" that isn't given in the problem. If you have a logic problem expressed in words, you accept _only_ the facts stated in the problem and see where that takes you.

The actual answer to the unstoppable force/immovable object paradox is that it's a math prank. An immovable object implies infinite inertia, which requires infinite mass, which can't exist in our universe as far as we know. Conversely, *all* forces are unstoppable, because every force affects every object it's applied to in some minute way, even if it's mostly imperceptible. To assume an immovable object could exist means we're not talking about our universe with it's laws of physics as they function, therefore you can make up anything you want about the universe you are talking about.

The 'set of all sets' one drives me mad because it's not a paradox. It's a mangling of the question "Does the set of all sets that do not contain themselves contain itself". The set of all sets does contain itself, because the set of all sets contains all sets, and is a set, therefore it must contain itself- and given that 'sets' are merely conceptual devices for grouping concepts, this isn't contradictory.

18:22 isn't actually the twin paradox. The paradox arises from the fact that motion is relative (that's why it's called relativity) - from the astronaut's point of view, they're motionless, and the twin on Earth (along with, you know, the entire Earth), is the one moving at nearly the speed of light, and should experience time dilation. So when the twins finally meet, does each one sees the other as younger than themself? This is in fact more of a mathematical prank type of paradox. Special relativity tells us that inertial motion is relative, and indeed, when the astronaut is moving at constant speed, they would experience their twin ad younger (but in order to experience each other, the twins must send signals to each other at the speed of light, which would add delay, so in order to know that the other one is actually younger, and not just appear this way because of the delay, they would have to do a bunch of math). However, for the twins to meet in person again, the astronaut must turn and fly back to Earth, which means they must accelerate, at which point they are no longer inertial, and are not equivalent to the twin that stayed on Earth.
