- At 09:08 I say “1 in 110 trillion” when I meant to say “1 in 110 billion”. The number on the screen is correct, it was just a verbal slip-up.
- At 25:27 I showed the 118 craps record as “1 in 1.2 × 10^9” when it should be “1 in 2.2 × 10^9”. The voiceover says the correct number.
- I slip and “more likely” instead of “less likely” at 33:47 (I think I may have even been going for “more unlikely”). But everything in the screen is correct.
- Let me know if you spot any more mistakes!

I've send you an attempted proof of the collatz conjecture mind checking it out? I need your help with part of the proof.
It was just one take right? You just got lucky!
i assume it is close to 0010(in binary) multiplied by cubic root of parkers square. Right?
The missing bracket just means that the rest of the paper, and indeed the rest of all existence after you started reading the formula, is now part of the formula.

@@crypt5129 I really don’t think that video is as definitive as it presented itself to be. Don’t get me wrong, love karl and his work, but this topic is still heavily up for debate. It shed a lot of light on stuff not talked about often, but a lot of the evidence was FROM the guy being accused, hearsay, and inferences. Which is valid pieces of evidence, but there’s still room for plausible doubt
I think my biggest problem though is the defense of his reaction to the problem near the end. There is no excuse for how much of a manchild dream was, and the amount of neglect he had for the moderators well being and his fan base’s rabid attacks. He has way too much influence than he knows what to do with and he can’t responsibly handle it
Dream when he’s walking down the street and suddenly wins the lottery while simultaneously getting struck by lightning and then is eaten by a shark:
Funnily enough this has similar odds to what dream accomplished in his "speedruns"
Odds of Winning the Lottery: 1 in 302.5 Million
Odds of Getting killed by a Shark: 1 in 264.1 Million
Odds of Being struck by Lightning: 1 in 500,000
Multiplied Together: 1 in 2.5 * 10^23, which is just 1 order of Magnitude less likely than Dream's luck.
@arrsea not by much, it’s actually pretty damn close.
@@jasonlewis4438 Winning the lottery is definitely not "just" 1 in 302.5 Million, so you could easily pick a lottery with a more favorable chance of winning, making the original statement true. By doing that you would have made the joke better, instead of trying to ruin it :-(

I was playing it while watching the video. How likely was that?
Well, very.. I was playing while browsing my YT subscriptions.
My probability class did an exercise... they had one student flip a coin 100 times, and another student was told to just write down H&T randomly, without any props. Professor claimed that he could tell which was the true random series from the coin, because the student doing it by hand would be too shy to put in appropriate-length strings of heads (or tails) in a row. It was a neat game!
ZzZzz
thats really interesting!
@@baritonesax245 It's been a while, but as I remember, you expect a string of log base 2(# flips) of heads or tails in a row somewhere in the sequence. The fake random sequences never had more than 2 or 3 HHH or TTT, even for 100 flips.
Numberphile did a video on this called randomness is random.
Where the host does 20 flips in his head and writes the down and the other person tries to predict what he picked.

Thanks for the enlightenment
DAMN. That really put that in perspective.
For reference, the diameter of our solar system from one side of the oort cloud to the other is about 1.5 light years. Basically, you could select a millimeter at any point on a line drawn between the surface of the earth and another point hundreds, if not thousands of star systems away, leave a marker on it, and the odds of randomly picking that point out of any other point would be dream's luck.

I thought they were two different videos rotascoped together. Because you never see his complete arm. Both are hiding below the frame and then bam, a trick shot.
I love the unspoken fact throughout the video that so many shots were filmed in order to get those perfect odds-defying results, like the book throw, the consecutive ball hoops, the dice pairs falling in the results in the right order.
Subtle, yet entertainingly on point.
It's a beautiful illustration of the question. Because I note that no one sees this and thinks matt legitimately did all that in one go. But it's way more believable that matt did that than Dream's result.
how is that subtle? lol
This reminds me of a quote I saw online from a journalism class. “If one source says it’s sunny outside and another says it’s pouring. Your job is not to cite both sources, it’s to look out the f*cking window and find out which is right.”

The fact that this man actually went to the lengths to understand minecraft is just wonderful
I dont think he went out and "understood" minecraft in the sense you're suggesting. It's a childs game with a simple premise, not too difficult of a concept to grasp. Not only that he seemed to have only examined the loot tables thoroughly, as that was what was in question.
Understanding minecraft, as you seem to mean, isn't as easy as knowing it involves gathering resources and killing a dragon
I think it's ironic because the dude understands so much about math XD
@@sakikogookheng I getcha... but Minecraft wasn't intended to be a kids game. It's a game for everyone. Not even Notch expected so many kids to be constantly playing the game.
Eh... I don’t play it but “get pearls, kill dragon” isn’t exactly the hardest thing to grasp. A quick look at the loot tables and you are set. Come on.
@@sakikogookheng
You clearly have never gotten into redstone, automatic farms, nor sorting machines. Minecraft, on the surface, is simple... Factorio, is simple on its’ surface- you crash landed on a foreign planet, build factories, build a rocket, then you win. But when you actually get into, it’s incredibly complex and requires math.
As a Minecraft lover, hearing you describe the process to beat the game made me realize just how strange this game is.
It's like listening to your parents try to explain your hobbies to their friends
To be fair, as far as video games go, "get gear, go to hell, get item, make item, go to weird hell, kill dragon" is pretty straight forward. But i do get what you mean.

@@NickersonGeneral No, that's impossible.
@@grondlegger939 reread the comment 🤦♂️🤦♂️
We should be doxxing dream and trashing their home for this.
Weather he admitted it or not, the argument from probability is fallacious. If the video was about how he admitted it, it would be be a different story.
This video is basically a "Dude Perfect" video with less yelling.
an more math
*Binomial Distribution*
I came into the comments to see all the dream stans arguing before I watched the video and I was very confused when I saw this comment
Just imagine Dude perfect got his perfect shot... AND THEN start doing the maths how likley the stunt whatsoever was to happen. lmao.
And without the obnoxious music...
So using Math, he basically "confirmed" everyones suspicion...the odds of Dream getting pearls and rods that fast are not 0, but boy it's the closest thing to 0
Basically, not zero, but it might as well be
As close to the asymptote as possible
If every person on the planet lived for a thousand centuries, (that's like pre-development of homo sapiens, to 500,000 ad?) And all those billions of vampires did, in a constant purgatory, was speed running Minecraft over and over. we would expect that one of them would have the experience that dream did... Probably.
Lol.
I think this is a lot like intelligent life. It is incredibly rare (by what we know) so it would be extremely unlikely for us to be here. But since we ARE here that kind of messes everything up. If the odds are 1/100000000 then that would mean that us being here could look like “cheating” but since we are here no math could dispute the fact.
ε>0 is the closest thing to 0
just for perspective, for the 10 billion human second century thing, it would have to take roughly 650.22 centuries for just a SINGLE occurrence of what happened to dream.
How did you work that out? (just curious have yet to take a class in statistics)
@@tes-cl3ru it's actually just almost straight arithmetic at that point. The probability of getting Dream's result is about 1:2*10^22. The 10BHSC is about 3*10^19
By multiplying these two numbers (raw probability and number of attempts) you get a new expected value, which is something along the lines of 1:650 (1:666 with the numbers I just provided)
So you're going to need 650 of those centuries to expect it to happen once. Or alternately for attempts to be even faster. Or the population to be higher.
Well and if we factor in that it takes more than 1 second to do all the accounted livestreams it would take a couple trillion years for a single occurence. Considering the age of universe we still have a couple of trillion years to go.

I love the concept of the 10 billion human second century, it's a really great way to put kind of abstract seeming, difficult to comprehend odds into perspective
The 10 billion human second century is brilliant. Really illustrated the point so clearly and made it possible to conceptualist such extreme odds
"What I'm saying is, if every single human in existence was doing a speedrun of Minecraft every single second around the clock-- every human doing it!-- for a century, the odds are still you would never see a result anywhere near what Dream got."
That settles it then.
It would take a thousand centuries for us to be pretty reasonably confident that it would happen.

Unless they say they got it on the first try, they could have had an infinite number of takes before hand.
This video is now mentioned on Dream's wikipedia page!
this video is older now but having the book land when you flip it behind you at 17:15 is SUCH a great touch when you just finished debunking the incredibly low possibilities of this being an honest speedrun lmaooo
And he continues with another minute of commentary without even a microexpression of excitement that he got the book to land.
And this friends is why you trust mathematicians who will put their name on their papers, rather than random, unnamed, and unknown astrophysicists.
Cause only one of them will willingly admit/defend when they bodge a paper.
^^^
this was a reason i gave to his rabid fans when i told them how research and finding reliable sources to work with is the best chance of dream being right
however it turned out dream literally just hired someone to do incredibly bad math and came from a wix website made a couple weeks prior to this event that still had its watermark of wix on it
Wrong. Never trust authority. Trust the rules of mathematics and read what they write, not who they are. Putting blind trust in people just because some university said they can put letters after their name is just stupid. And a cause of a lot of the issues we see in the world.
In the dream case , the mathematics is simple. You can work it out yourself with a calculator.
It's not enough for the scientist to put his name, considering all the potential conflict of interests in the real world, when it is not about Minecraft, but medical statistic justifying lockdowns or the lethality of a virus. In fact, I would say that only independend scientists are real scientists, everyone else is a scientific prostitute creating the numbers which are wanted by his clients. (the people who order the study to prove their ideology correctly)
Funnily enough, the scientist did redact the initial paper saying that there were alot of mistakes, mainly due to not understanding the game. Which makes sense. And btw he didn't want to put his name on the paper cause he didn't want to get public backlash from it, and lets face even if dream was innocent and the paper just proved it, he still would get alot of backlash. And in a time where having a job is so important and finding work is incredibly difficult think it's fair to want to stay anonymous to stop people calling for you to get fired, which does happen.
To put that kind of "luck" in perspective, flip a penny 13 times, and if it lands on heads on all 13 times, go buy 3 lottery tickets with 1/1000000 chances of winning, if you win all 3 lottery tickets, that's the kind of luck dream would have had to have to pull that off legitimately.
This comment needs more love. Jesus Christ the maths there.
@@binomial3837 No. 1 in 7.5 trillion was actually the upper bound on the chance that ANYONE would ever get Dream's luck on any set of runs. For just a random session of 6 livestreams, to get Dream's luck, it's closer to 1 in 10^22.

Just a note on the odds on those craps runs because your math ends up off because of it.
The 154 roll streak was without crapping out (losing) *not* without rolling a 7. There could (almost certainly were) 7's in that run. It could have even been literally all 7's. The number for the losing roll varies depending on the phase of the game you're in.
One "game" of craps consists of one or two phases. You start with a "coming out" roll. If you roll a 7 or 11 you win immediately. If you roll a 2, 3, or 12, you lose immediately. If you roll 4, 5, 6, 8, 9, or 10 that becomes your "point" and you enter the second phase. In the second phase, you win if you roll your point number before rolling a 7 and lose if you roll a 7.
Thanks for clearing that up. I remember trying to learn how to play craps once and couldnt get my head around it, but it definitely was more complex than how it was described in the video
Wait, so they were counted as 154 rolls, which would be less than 154 rounds, right? And it sounds like every roll has a smaller chance of making you lose immediately than just "not rolling 7", so the real chances would be slightly higher than what Matt calculated.
The fact that a physicist did the math for Dream should tell you everything you need to know.

so glad I read your comment! You're not alone...
Making this video might be the single smartest thing Matt's ever done on his TH-cam channel. It's only a year and a half old but it's his second-most popular video, second only to his Dr. Nim video which is 5 years older. And I'm sure it attracted a ton of newcomers from the Minecraft community.
It’s also perfectly placed in the timeline of events that happened, adding in a purely mathematical perspective to the equation. It served its purpose of helping explain the numbers further, and thats where it shall stay in history
Its like if you flip 15 coins, and they all get hit by different meteors.
If only this video came out about 8 years ago when I was trying to present my thesis on "Teaching Math with Minecraft"
hi anton :)

@James R It felt natural. I skipped the actual math though because I'm on my phone.
This video is especially fun to watch after seeing the one with Hannah Fry on Bayesian statistics where Matt repeatedly fails to throw a ball onto a table. But now, he *very mysteriously* cannot miss a target! Also, the explanation of the math is superb.
I enjoy coming back to this one every so often because of how evergreen this video is.
Despite being focused on what is now a years-old, and largely resolved, controversy, the core of what he's teaching us about throughout the entire thing is just as relevant today as it was then. The inherently suspicious nature of maths chaff, a simple tool of comparison for how likely a thing is in our universe, even simple things like how to understand scientific notation. It's a true masterpiece of a video, and the level of effort that must have gone into it really shines through.
And not just because of the impossible shots he made in the background - though, every time I come back, I do wonder how the probabilities of the various shots he took match up to Dream's theoretical odds.
You know I was trying to understand why I keep coming back to this video. Now I know.
Same. :)
Hearing Matt say the words "Ender Pearl" and "Blaze Rods" is a strange phenomenon.

Tbf, he had some bad luck with the end portal. Before that, he was on WR pace.
@@danielf.7151 that's a shame, he should've set the portal's spawn to be closer

This is one of my favourites for the simple fact Matt came up with a human second century to make it easily understandable
You totally aced it, and you brought back the discussion to the level it belongs. Deep maths and statistics shall not be abused unless necessary.
One cheater made a full community to learn binomial distributions.
The truth is that he actually did this stunt in order to further maths education in the world. Dream is a true unrecognised saint!
@@Blobbyo25 the fame, glory and internet recognition was, of course, just a side effect. Not intended at all :)
@@Blobbyo25 ah yes of course
Dream is also Jesus's son
I was kinda on dream's side. But then I saw the parenthesis wasn't closed in the papers that sided with him. Unforgivable.
I kinda think he’s stupid
To be fair, even though in this specific context the missing parenthesis doesn't matter, a misplaced parenthesis could result in completely different equations.
@@tiredboard I would assume a professional doing analysis for a paying customer would be more focused on details like that when dealing with math. That's ignoring someone not willing to putting their name on their work.
@@erronblack308 who? Dream?
You saying that a world-renowned mathematician would seriously not remember to close a parenthesis? I mean if you dedicated your life to math you would pretty much not make this kind of mistake. Face it; Dream himself wrote it to look better or the "mathematician" does not know what he is talking about.
I really love the level of detail the speedrunning judges went into for the paper. You call it rambly, I call it Great Effort! genuinely really good work. you did it better but to be fair you are a famous mathematician lol
I failed maths GCSE in secondary school and had to redo it in college where I barely passed. I understand on an intellectual level that maths is genuinely beautiful in its order and magical in its ability to be strange and chaotic.
It is the backbone of science that I love and the lore behind scifi sometimes relies upon maths to backfill the details from the stuff made up on the fly to suit stories. I am talking here about how nerds know how warp drive works, how fast the different ships go in different eras and how many shuttles and torpedoes Voyager had and used. The maths isn't what you do but it's there as a background.
Then there's the maths of how games like Minecraft are coded. How you can enter the same seed and the world will generate in the same way (at least to a certain extent. I'm not sure if there comes a point where the generation has built on generation enough that two worlds with the same seed are different).
I have been watching videos from James Hoffman this past Christmas about coffee and that involves maths, videos about chemistry from Nile red and that involves maths.
On a more practical level I've been playing Fallout 4 with mods and had to come up against the mathematical limitations of the code and my machine.
All this to say I am bad at maths and while I respect its role in the things I love I hate it because I suck st it. The first time I can remember having a panic attack it was because I was in an advanced GCSE class about some kind of maths and my impression was that we were being told to divide in a way that made numbers bigger and my brain could not cope. In hindsight it was probably phrasing i.e. that if you cut a log in half say you end up with two bits of wood so it's phrasing as dividing but was actually multiplication. At the time my brain just melted down.
I came to this video for the Minecraft but not knowing or caring who Dream is and not liking maths. I loved the video and you explained it well. Though my idiot brain still says that it doesn't seem that unlikely to get drops that to my idiot brain don't feel that egregious. I am bad at maths so I know I am wrong but it's interesting that even after my video my brain is going "I don't know though..." Lol
i like what you said about it being the difference between deliberately throwing a dart from a plane to hit a bullseye and throwing a dart from the plane, it landing point down and you then drawing a bullseye around it because as someone bad about maths I only know about probability when it's improbable. Stories are not written about the predictable. Videos are not made talking about the usual so to my brain a once in a lifetime occurrence feels like it happens regularly. I've watched ocean liner and engineering disaster videos where the videos are made because the metaphorical dart from the plane landed face down where a bullseye could be drawn. They were random spikes in the broth of chaos that happens all the time but were singled out as different from the broth and my perception of plausibility comes from seeing so many of these rare spikes.
Tldr great video subscribed
I can't tell if the book-toss was:
1) Good enough to count, no more takes, just move on.
2) Better than intended, since it didn't slot into the others but it's upright and fully visible.
3) Exactly as intended.
I was wondering the same, im gonna go with 2 haha!
1. Definitely. It almost sloted perfectly: should that not be the objective, it should have had become the objective.

GEOSQUARE S Q U A S H E D
This video aged very well given that he admitted to having an rng mod
He failed to gaslight his fans now he's force to admit it 😆
The look of pride and satisfaction when he looked to see if he hit the bullseye and saw he finally did is priceless. Plus keeping up the level of expressive narration after that many takes is impressive in and of itself. Just genuinely impressed with this channel especially because I know you do another channel that's way more serious but I can't place atm.
Dude holy crap. Like, I look at “getting 42/262 when 12/262 is the drop rate” and think “eh that’s lucky but doesn’t seem insane” until you actually do the math on it. That’s bonkers.
Yeah. The intuition that's important to have is that doubling the amount of trials obviously doubles the mean, but it doesn't double the standard deviation (how much we expect something to vary)
It only multiplies that by the *square root* of two.
So when if you have *four* times the amount of trials, you only get twice the deviation, even though the mean is four times as big. So suddenly this relatively small deviation (in absolute terms) becomes a completely unsurmountable mountain.
@@XCC23 I know you're right but intuitively it still feels like the odds should be similar to getting 4/26 when you expect 1/26.
Funny thing is, that same intuition is why we know about the cheating: the hacker knew they couldn't make things TOO lucky, but they used their intuition instead of crunching the numbers and they inadvertently made a change drastic enough to expose them.
What this makes me wonder about is how many other, smarter cheaters may be out there, manipulating game probabilities just by a standard deviation here and there, gaining an edge while maintaining plausible deniability.
@@Alec____ how many heads do you expect to get if you flip a coin once? 0.5
If you flip a coin 100 times? 50.
@@polendri4812 Well, you do have to keep in mind that for every game they play they need to make sure the standard deviation is going to even out. If Dream had used the hack for a small amount of runs, it easily could've been chalked down to luck.
Imagine cheating and still not breaking the record
Tbf the WR run is going to have the same luck, this just gives dream many more possible chances to have a run with the rng where he just has to do well
Not saying dream isn't in the wrong though screw him

@@xrefed True true.
@@xrefed - Karl Jobst
Funny you say that, because when Dream got to the stronghold he WAS in world record pace. The reason he placed 4th was because he lost considerable time finding the ended portal. Had he gotten lucky in the portal spawn, he could’ve placed much higher. Maybe even first place!
as a cuber, I cant stop looking at the conjoined megaminx in the background
I appreciated how you made your points without wading into speculation or assigning blame. The human-second-century is a nice way to get some intuition in a very unintuitive range of probabilities. Thanks!
One of the beautiful and frustrating things about probability is that everything can look familiar and be strange or look strange and be familiar or look strange and be strange. All you can do is calculate to understand.
This is what would’ve happened if Dream actually hired a statistics expert.
Well maybe a few before told them, no way bro ;)
He likely didn't hire a statistics expert, but an expert in obfuscating statistics. Those are very useful when you're trying to hide that you are cheating.
@@Taeerom Yes in the interview with DarkViperAU he himself admits during the interview the statistics person he hired was not even well enough informed, and did not really understand exactly what this was, but helped anyways. He said the professor or whoever he talked to wanted to actually do a lot more work now that he knows what's going on, and was a bit upset at dream for kinda making him look bad. I can't remember everything that was said. IT was a lot of hiding a lot of the facts though.
@@lunova6165 Thank god his name wasn't in there then.
Honestly? I wouldn't be surprised if he tried. They proved him wrong, and he had to go to someone else.

Me: I'm here for Minecraft and for the math, what then?
Matt's Method is phenomenal. At least to me as a non mathematician it seems so elegant. Upper bounds are standart in maths I know, but used like this it shows why its useful.
There is a fairly brutal dunk in here as well, one that Matt is too nice to go for, but it is completely mercieless.
This is too lucky to be true, one person cannot expect to have results anywhere close to this - Well but there is a lot of people trying to get this, maybe if... - No. All of humanity trying wouldn't make this plausible. - But What if people were really dedicated and spent a lot of time trying it? - No, all of humanity wouldn't get this if they spent the next century trying - But speedrunners are really good, they know when a run is not gonna make it, they will just reset, what if Dream was just incredible at optimizing? - No, the model assumes all of humanity is absolutely insane at speedrunning and takes on average a second per run. They aren't taking breaks either btw, not to eat, drink, sleep or work, this is all they do for a full century, and they still only have odds of one in a thousand
It is a fantastically elegant method. But we've gotta remember, it only works because Dream's claimed result is ludicrous. So ludicrous that if we set the upper bound millions of times above the rarest observed event in a game of chance, we still don't catch Dream's result.
For anything that's a little bit more reasonable, this method's not going to help.
putting the odds in terms of craps and roulette actually made it way easier to comprehend
I feel like Matt severely underestimates how much of his audience associates themselves with Minecraft.
Jupp. Just set up a server with friends after the server we played on turned out to have been run by someone who was a total boomer about security.
I think you overestimate how much his audience does.
@@Ebani You're saying the same thing as op. Overastimating the number of people that do NOT play minecraft means that more people than previously thought do play it.
@@katacutie You're right, wrote it fast and didn't check as i was actually gonna write a longer sentence

The "10 Billion Human Second Century" is one of the funniest things I've ever heard in mathematics. Also genius in how easy it is to convey to the public at large.

Hell, I'm a mathematician and it's really conveying to me.

I love how indepth your efforts are in explaining this while managing to keep the over all ideas in layman's terms. Brilliant. I want to make two comments because of it. (Appologize if my first thought isn't well explained but I will attempt to do my best.)
1) It reminds me about highschool math and how if is often harder to add ideas/areas together is often harder than trying to take the larger shape/upper bound and substract from that to prove your result. Your method reminds me of that because I remember always forgeting to think about that option in working an idea out.
2) It makes me wonder what is the LUCKIEST EVER event an individual has achieved (both proven and/or unproven) to have existed.
Anyways, thank you for the video.

The odds don't mean anything and don't matter since he did the run and it happened.(actual quote from a dream stan)
I love the 2x10^22 probability when looking at a "History of the universe dartboard"
If you were to throw a dart at a random second on a timeline that spanned between the moment the universe came into existence to today (13.7 billion years), the probability of hitting any particular second of time is 4.3x10^17.... which is still a significantly better odds than the drop rate he got.
How much better? well, take the length of the universe and multiply it 50,000 times and throw the same dart. He would have had to hit a specific second of time in a timeline that is 685 TRILLION years long.
Another way to look at it, is to pick a grain of sand on the entire globe. There is estimated 7.5x10^21 grains of sand in the world.... Now, double the size of the world and do it again. It's still a better chance to pick that single grain of sand in a world that is twice as large as Earth.
