"TREE vs Graham's Number" is basically clickbait for mathematicians
I mean yeah it’s clickbate but in fairness they weren’t lying
TREE won by a landslide... A landslide of orders of infinities!
no coz if u know this its obvious whats bigger and u gain nothing new from the vid. but people who didnt knew can gain something
I'm not mathematically smart.......but i due enjoy learning about big numbers and I mean BIG numbers like the ones larger than the ones in this video. Like Fish number, etc

If each of my brain cells was a brain, lets just call that an omega brain, I still wouldn't understand this.
This makes my brain feel like it is a brain cell.
Yeah, but what if each of your brain cells contained as many brains, as your brain has brain cells? No, wait, what if each of your brain cells contained as many brains, as the number of possible permutations on the set of all brain cells in all of the brains in all universes real and imaginary? No, wait, what if all brains were like that, and then what if each of your brain cells could produce that many new brains per nanosecond, for each possible permutation on the set of all of the brain cells in all of those brains?
😂
If I had a TREE(g(Γ₀!))-brain for every 1/(TREE(g(Γ₀!))) Planck Volume within the known universe (let's just call that a Ж-brain), and then had Ж Ж-brains for every one of those,

Ps it should not be too hard to figure out the heights for whole numbers like 0,1,2,3,4... even if some of them you have to use a weird mathematical function to show the answer (Like even weirder than power towers.).
5:16 "You're giving the TREE more juice". This was the funniest, most succinct way to describe the same intuition I had!
I'm not sure what the term is for "rate expansion".
For now "rate expansion" = juice.
Juicing the equation
I thought of it like this. The tree function gives much larger values than the g function. So at the enormous scales that we're talking about, all that matters is what is inside the tree function. So tree(g64) is better than g(tree(64)) because you're giving a bigger number to tree. It doesn't even matter what g is doing at this point.
...in other words, giving the juice to TREE, not g 😉. Give that tree more juice!

So sure, Tree(Graham’s Number) is big. But I have just been exploring the harmonic series (1 + 1/2 + 1/3 + 1/4 + 1/5 …). It is divergent. It takes around 10^43 terms just to get it to sum to a hundred, and it gets way way slower after that.
So my number (‘Geoff’s Number’ if no one has claimed this before) is:
“The number of terms required for the harmonic series to sum to Tree (Graham’s Number)”.
Pin this comment
The amount of terms needed is approximately e^(Tree(Grahamsnumber)-gamma)
where gamma is the euler mascheroni constant
@@hybmnzz2658 I’ll have to take your word on that. Sounds big.
@@GeoffBeggswell 1+1/2+1/3+...+1/n approximately ln(n)+euler m constant and the approximation gets better and better the larger the n. Because tree(g(64)) is so massive, e^(tree(g(64)-euler m constant) number of term is super sccurate approximation
@@GeoffBeggs yes, it is the same size as TREE(Graham’s number). When you are dealing with numbers this big, raising them to a power doesn’t make much difference.

Is it me, or does 20 million suddenly sound like a pathetically small number
time to plant TREE(3) trees
Time to plant TREE(TREE(TREE(....tree(64) times...))) trees
120million digits sounds like nothing at all, given what they are looking at
That's basically a day's worth of disposable chopsticks in China.
Thanks internet, Now Chinese can enjoy eating for an extra day.
Actually first thing I thought when I heard about that project was:"20 million threes are not so much at all"
This is absolutely the best explanation I've seen of just how much more massive TREE(3) is than g64.
If you look at it through the levels of googology: level 0 is all the single digit and small numbers tending to zero; then level 1 goes from double-digits to a million; then level 2 goes beyond this all the way to a million digits (yes, googol and virtually every number we can practically deal with in our observable universe doesn't even get past level 2); level 3 starts entering the realms of tetration with googolplex and the likes; level 4 goes well beyond googolplexian and so on. You can see how going up just one level in the realms of googology gets to even greater magnitudes much further away than the levels before it. Well, G1 sits around level 6 or 7 and then G64 is much further at level 12, with fw(n) starting here or the level before it (11) let that sink in. So you can see that the difference between 12 levels is the difference between mere counting and shooting past G64 by iterating the number of arrows. Now you run through all the ordinals from omega through epsilon, zeta, eta until you reach the insane gamma-zero; the latter is all the way up to level 100 in the fast-growing hierarchy, meaning that counting to even G(G(...G(64))) [G64 iterations] would be much faster than using the G(n) function (or even f-epsilon0 for that matter) to reach the monsters produced by fgamma-zero(n). However, even then TREE(3) would laugh at this, as it's all the way up in level 120. That's right, an entire 20 levels ahead of fgamma-zero(n), which is insanely further apart than 0-1 and G64 which is merely 12 levels. This means even using fgamma-zero(n) to reach TREE(3) would be much slower (which is still an understatement) than merely counting to G64, even if you were to count in base 1/G64.
It's crazy that such a simple "game" to explain, like TREE(n), which you may easily explain to even a first grader, is so insanely more powerful than even Γ₀, which requires pretty advanced mathematics to even begin conceptualizing.
Mathematics is beautiful!
TREE(n) lies between the SVO and LVO in fast growing hierarchy. The SVO is lower bound and LVO the upper bound. It is much closer to the SVO but slightly faster than that
The SVO and LVO is just ridiculous just to let you know. If you want i can link a video to explain these ordinals. Then you will understand why Tony said in the video that anything beyond gamma gets messy😂😂

Fascinating that g and TREE are so fast growing that you need transfinite ordinals to put them in a hierarchy. This is probably the best way to convey their power.
It's amazing that even without the ordinal Mathematics, we can still tell that TREE function grows (way) more quickly than Graham's function. TREE(n) literally goes from 1 to 3 to something that is way way way way way bigger than Graham's number, while G(n) needs 64 layers to go from 3^^^^3 to Graham's number. It's absolutely safe to say that at least the numbers G(1) to G(64) are all within the gap between 3 and TREE(3). The jumping between G(n) is essentially stationary compared to that between TREE(n).
Exactly 👌🏻.
G(0) is also 4 so basically the entire graham sequence

These ordinals are beyond gamma. I can link a video to explain these ordinals if you want. You will then understand why Tony said in this video that anything beyond gamma gets messy😂
Things can start slowly then get really big later though. Tree is still a computable function. The Busy Beaver function has pretty reasonable values for small values, but it grows much faster than any computable function.

22:51 Yoooo that is actually scary. I knew TREE was big, but I did not expect that.
TREE(n) is believed to grow at least as fast as the Small Veblen Ordinal or SVO for short. SVO is beyond Gamma in strength
I love hoe much passion he has for numbers!!
The TREE function impresses me everytime. It's so simple yet it blows everything away.
Just wait, one day they'll finally explain the Busy Beaver function BB(n), which grows so fast there literally cannot exist a function that can compute any of its digits. It's insane just how fast it grows. I heard that even getting a lower bound on BB(20000) is impossible in ZFC. Of course, BB(n) is tiny compared to its relativized cousins. And we aren't even out of the lower attic yet. In the middle and upper attic, there are numbers so large that you need to add extra axioms to ZFC in order for them to exist.
@@knightoflambda what is the most faster growing fiction in googology?
@@knightoflambda I think they already did an episode on BB. Scott Aaronson proved that computing BB(~8000) requires proving the (in)consistency of ZFC (basically brute forces some statement that is true IFF ZFC is consistent).
@@knightoflambda they mentioned and explained some Busy Beaver stuff in the video about Rayo's number
@@knightoflambda actually it is true that BB(n)>TREE(n) for n>k for some k value. But my guess is that "k" is huge itself - I mean it may be bigger than Graham's number. So while it is true that BB is a faster growing function than TREE it doesn't mean that in the region of "normal" numbers BB(n) is bigger than TREE(n) :-)

Never thought transfinite ordinals could be useful with something finite like sequences of integers.
Amazing video!
Oh man. You should look up the proof of Goodsteins theorem, using trans finite ordinals.
Its a statement about sequences of numbers which is proven using ordinals.
All the ordinals that were mentioned in this video were still countable, i.e. they can be viewed as representing a (non-standard) ordering of the natural numbers. That is to say, the transfinite ordinals play the role of intrudcing jumps (in this case the jump is taking the diagonal in the constuction of f's). As such, the cardinalities of any of those ordinals is N, and thus all still smaller than that of the reals R.

the thing I dislike about numberphile is that they never explain how people figured out anything and so you're just left feeling as though you didn't really learn anything but instead just heard of something
I agree, but I understand why they don't.
Its pretty easy for folk like me with an IQ of 80 so these folks with IQ nearly fifty percent higher can understand these numbers and the growth rate by which numbers are made. That is true but the FGH they mention in this video is like addition compared to the highest ordinal they mentioned ok said video. This process goes on for infinity. So absolutely infinity can't exist since there is more than an infinite amount of such.

This could be perfectly fine in the context of the quote, as tai lung thought he would defeat the dragon warrior, but in fact got stomped as if he was nothing.
Later in the fight: “The Wu Shi finger hold?!?!?! Shi Fu didn’t teach you that!!!!!!!”
“Nah, I figured it out. Scadoosh!!”
@@jolez_4869 Even TREE(TREE(3)) won't match SSCG(3). SSCG is for 'simple sub-cubic graph,' and it works similarly to the tree problem and resulting function, except there are fewer rules for simple sub-cubic graphs, making more graphs possible, and therefore (much, much, much...) longer sequences. SSCG(n) forms a similar sequence to TREE(n) (in that it describes maximum lengths of non-repeating sequences for a given number of tags, and in starting small and exploding by n=3), but outpaces it easily -- SSCG(3) is greater than TREE(TREE(TREE(TREE(TREE(...TREE(3)))))) -- if you nested that TREE(3) layers deep.
TM,DR (Too math, didn't read) -- there's always a bigger function.
@@isaacwebb7918 Wow damn. Thats interesting!
This channel is 100x more interesting than any math class I have ever had
Numberphile: Donate for Trees!
Also Numberphile: USES TREMENDUS AMOUNT OF PAPER
Entirely logical. They need many MANY moar trees for all their paper. So they ask people to fund more trees. Makes eminent sense to me!
I remember the VSauce video on Ordinal Numbers and Infinities; I was prepared for this one. Still amazing that TREE grows even faster than that!
People: there's no way Numberphile can join the #teamtrees thing
Numberphile: hold my beer
Hold my Klein bottle.
@@masterimbecile darn it should have seen that joke
With the amount of paper used in these videos I'd be shocked if they didn't
Well he did use paper...
Hold my juice
I read a cool description of Graham's number somewhere, in terms of trying to picture it in universal physical terms. If my memory serves me, it went like this: It said that even the integer describing the number of digits in Grahams number could not be represented if you made every particle in the universe a digit, and the same would be true for the number of digits in THAT number, and even if you went down that "number-of-digits-in-the-previous number" scale, with each level down being represented by a single particle in the universe, you still would not able able to fit it into the known universe. I wish I could find that again.
In fact, g(1) itself, defined as 3↑↑↑↑3, is bigger than googolplexplex...plexplex (with googolplex 'plex'es)
In fact, the number of digits in Graham's number is approximately Graham's number...
its on wikipedia
LOVED this video.
Making all these videos Brady practically became a mathematician.
Ah the iconic “Paper Change” music returns
These videos are fascinating.
15:20 *THAT ESCALATED QUICKLY* XD
I remember being outside his office when they were filming this 😂
Andrew Dawson Truth or lie 🤔
This really exceeds my ability to comprehend.
Don't worry, it exceeds the physical universe's ability to comprehend too.
i love in a video about combining graham's number and TREE(3), just the integer 3 on its own is described as a "big number" also
Just the fact that no finite f(n) hierarchy could describe the growth rate of Graham's number, let alone TREE(n), blows mind mind. Truly shows how unimaginably large those numbers are.
I love the hint of fear that trickles through his enthusiasm when discussing the functions over Gamma-Naught: "We must tread lightly here, lest we disturb the Old Ones who dwell in these regions..."
Oh, I’ve missed the “Brown Paper Chronicles”. Thank you for this 😚
15:19 "that escalated quickly"
best use of that idiom ever.
It's been nice knowing you guys. My head is going to explode now.
And as everyone knows we get Omega-3 from fish. So this video is telling me: plant Trees using fish.
a herring!
@@DFPercush *jarring chord*
i hate this joke
At this point my entire subscription feed has been replaced by trees. I guess I'm okay with that.
Understanding the math sequence is beyond me. But watching Tony get excited about math is so entertaining.
