π = 3 + a bit.
Going to use this in all of my code from now on.
π = 3;
π += a bit;
private double aBit = Math.random();
private double giveOrTake = Math.random();
if (giveOrTake > aBit) { aBit += giveOrTake; }
if (giveOrTake < aBit) { aBit -= giveOrTake; }
private final static double PI = 3 + aBit;
pi = pi + bit

so π will be either 6 or 7 depending on the value of that bit :P
This was one of the best Numberphile videos ever.
Ersen Couldn't agree more
I never liked the golden ratio because the way I learned it was:
1. greek dude came up with a series
2. divide 2 following numbers in it
3. WOW! flowers grow this way
4. the end
This was a very unsatisfying explanation, because the whole 'WHY?!?' was missing.
Thanks for giving me some love for the golden ratio.
I agree. This one is up there as a top candidate for the best one ever. (And I have of course seen every single one, as we all have. Surely.)
I was going to post the same thing. But I knew someone else already must have. So I found your comment, liked it, and...

@pyropulse You seem upset. You wanna talk about that?
pyropulse pretty rude for no reason
pyropulse I mean I found it interesting that this could be a way to visualize how closely can an irrational number be approximated by smaller numbers, and I think using the language he used to explain - “more or less irrational” is an easy way to express my thoughts in this context
This is the absolute best explanation of the Golden Ratio I have ever seen. Thank you!
For me it was the sound dinosaurs that did it.
The golden ratio is 1,618
Establishment is training Al to learn from revised/censored reality of mediiaa and internet (mostly peaceful 👍), manufactured by NewNormal agenda. Starting the systemic use of Al with special interest focus is pure corruption at the root,. thanks Sillyc0nVally
Nature is so precise. And yet many people still call themselves "atheists".
@@RaineriHakkarainenApproximately. It’s really 1,618…. Since it’s irrational (as indicated by its infinite continued fraction and its precise formula:
(1 + sqrt(5))/2 (which is just sqrt(5) with some rational tweaks); as 5 is not a square number, its square root has to be irrational), and a bunch of other things, I’m sure), it has an infinite, non-periodic decimal expansion. 1,618 is a rational number that can be expressed as a precise fraction: 809/500.
"I'll be there in a bit" = "I'll be there in a pi minus 3"

This is perhaps in the absolute TOP3 episodes of numberphile... everything is so great, I've watched it at least 4 times now over the past couple of years since I got into the channel. The content is fascinating, I love this dude, the animations and the music is soooo freaking perfect - even the little snaps when it pauses for a sec' ... just a wonderful peice of art created here
Why do they call it the golden ratio?
That was mind-blowing, watching that animation run. You could see the whole-number fractions passing as the animation proceeded. It's almost like watching some part of the universe that you can't normally see, but which was somehow exposed by this video. A bit unsettling, yet completely fascinating. I can't quite describe it.
Great. Glad you (sort of) liked it.
.
Is the code for the animation, or anything like it, available anywhere…maybe on GitHub?
AGREED! (and yes, that required caps.. lol)
yea but to me math is like super complicated but at the end of the day it seems to me its just like a never ending mandelbrot set. it seems we have came up with infinite amounts of knowledge to describe something we should have already known all along lol idk man im having one of those "bruh i just figured out how the universe works" moments.

Hadn't heard of the golden ratio being the "most irrational" number before, that's pretty cool.
Spectrally Mathologer did a video on this once. I think it was even titled "the most irrational number"
An unpublished interview with Steve Mould had him mentioning the Golden Ratio as the most irrational number.
It doesn't make lot of sense , if (1+sqr(5))/2 is the most irrational number , multiplying this number by 2 & substracting 1 shouldn't drasticly change it's properties , does it mean sqr(5) is extremely irrational ?
Sqrt(5) has the continued fraction 2+1/(4+1/(4+1/(4+1/(4+...
It's a similar beast in that it has a continuing fraction that repeats the same number over and over again. You can prove it in a similar way to the way he proved the all-1's continued fraction equals phi.
sqrt(5) = 2+1/(4+1/(4+1/(4+...), so according to this video, it would be more rational than sqrt(2) and sqrt(7). It has to do with proximity to a perfect square. sqrt(2) = 1+1/(2..., and sqrt(5) = 2+1/(4..., and sqrt(10) = 3+1/(6... If you look at the numbers, you get sqrt(1+x^2) = 1+1/(2x..., which means that when you take the square root of a number, the closer that number is to a perfect square, the more rational it will be (according to this video).
Glad to see that the steward of Gondor is alive and well!

6:10 also, if you count the number of seeds on one of the 3 spirals starting at the center, then the 7th seed will always line up with one of the 22 spokes - and 22/7 is approximately pi, amazing!
I have heard nearly everything in here before, but I've never seen such a succinct, logical explanation for all of it. This was freaking amazing.

Same. I knew about most of the properties of the golden ratio that were shown here, but I was never quite able to put together _why_ it was the case. When he went from the continued fraction representation straight to "x = 1 + 1/x" it just blew my mind.

Wow!!! I already thought I knew a lot about the golden ratio, but I've never thought of one irrational number as being "more irrational than another". The way they calculated phi from that infinite fraction is something I've never seen before and it was absolutely awesome!
It's a different metric but I thought of transcendental numbers as the most irrational but things like "e" and pi are close to 3 so will make curly spokes if you try to use 1/e or 1/pi to space seeds.
I have spent years of academia studying the golden ratio and yet this is the best and clearest explanation I have ever seen on its irrationality! Incredible!

Slower. Imagine it spinning slowly with a hypnotyzing music as it crosses the milestones. (the larger fractions, the golden ratio, etc.)
Looping wouldn't really have much meaning.
Make it 10 hours.
This is, by far, the best explanation about how math helps to explain natural occurences. I am a high school geometry teacher with a degree in secondary mathematics education. I always feel that when I start to talk about Fibonacci numbers, the Golden Ratio, etc, I tend to lose people. Most high schools students, and students beyond high school, really sort of start to glaze over when talking about sequences. I absolutely love this explanation and animation. I feel like anyone could understand it because it's so beautifully done. Also, to be honest, I never thought about the fact that some irrational numbers are more irrational than others. This video was so cool! Thank you!

Considering that flowers have had about 250 million years of evolutionary trial and error to progressively find more and more efficient seed packing methods, is it any surprise that eventually they would get to the most perfect method mathematically possible?
Not even then, since flowers don't have any sort of "choice" about where they grow seeds anyway. That's all determined by the behavior of the proteins down at the molecular level.
Exactly. When I said flowers "found" the best solution, I didn't mean consciously. I meant in the sense that a repeating computer algorithm might "find" the best solution to something if it cycles through the problem enough times.
Then every plant should have this structure. But they dont.
@@SuperQuwertz not every plant has the same goal...
Other plants with different goals find other uncannily mathematical sequences.
Like how leaves grow on a tree for example.
@@brokenwave6125 the goal should be to survive. therefore after millions of years everything should be more or less equal. there is no need to be "beautiful". bees dont care about the perfect geometry of a flower. Or do you think the lotus is repelling dirt and is using perfect geometry in order to survive better?
Nature: *Exists*
Mathematicians: _That's Irrational_
Irrational in math means something else compared to irrational in reality. Rational typically means "in accordance with logic." In that sense it's latin root. Irrational in that sense means not according to logic. However, that is not the etymological root of mathematical rational and irrational. The english started using ratio, which has the same root at rational, to refer to a relationship(by division) between two numbers. Rational in that sense means able to be described in a ratio and irrational simply means unable to be described in a ratio, not that the number is illogical - since numbers kind of can't be illogical because of how they're defined.

Quite different to be taught something compared to be the one that figured it out. Uff, one part of me wants to study again since i never got much education. Now at older age knowledge interest me more :D
Mine was actually pretty easy it was simply a matter of all actions being compressed into a series of yes no and i do not know from there you simply compress the possible repetitive calculations down to a reasonable form like holographic in a particular way then no matter what question you have as long as the answer is yes or no you have a direct path from question and answer in the fractal patterns of that holographic that eventually themselves repeat and the world becomes yours. Took me less than a day to figure out and usually just takes a few seconds on paper.

"The words a bit are not mathematically recognized terminology"
Computer scientists: :/
Great video. I really dislike the rectangle explanation of the golden ratio, it makes it seem so arbitrarily. Saying "it's the least rational number" is a much better way of highlighting its importance.
I think that must be a legacy from the Ancient Greek mathematicians. For them, numbers were for quantifying lengths (and areas and volumes), so the shape or aspect ratio of a rectangle comes out naturally.
Continued fractions are always fun.
They make me wonder if a musical interval of 1/phi should be the harshest possible ratio, not the tritone (which is 1/sqrt(2)). But if you try to make 1/phi, what you hear is a sharp minor sixth, closely approximated by 8 semitones and 33 cents.
The next question is on the 36 tone scale, where would this golden interval resolve?

flower seem to be better at math than me.
They use an evolutionary algorithm. They do not know that they are solving a maths problem, but nature put in the constraints and they just blasted out that optimum.
Maybe there were Root Two seeder sunflowers kicking around for a while before their Golden Ratio cousins took over.
+Thumper Maybe you're right. But if it's the Root Two seeders followed by the Golden Ratios, who's next? Maybe the Eulers? (Check out the evolution at 1/e, or around 0.36788, where the seeding looks maybe even more random than at 0.618...)
Its biology whose smarter then u
idling dove nice thinking on evolution, poor thinking mathematically. Did you even watch the video the Golden ratio was the ultimate randomness factor because it is the 1/(1+1/(1+...)))... so 1/e would be less 'irrational'. On the other hand their could have been 1/e sunflowers already that also got beaten out by the Golden Ratio ones. Also maybe some sunflowers are closer to the golden ratio than others and they are still evolving towards that perfect design (only to go extinct due to completely unrelated climate or ecological changes).
I believe there are still some plants that use a slightly less irrational number in the angular spacing of their branches. Maybe evolution is satisfied or is still busy optimising

I first came across this property of phi in golden angle-based MRI approaches as part of my doctoral studies. The basic idea is that when you're scanning, the thing you're scanning is evolving with time, but you can only scan one point in k-space at a time. (k-space is a spatial frequency space, but you could think of it as real/image space without losing the take-home here.) If you want to get the "most uncorrelated" data and therefore use your scan time most wisely, or if you want to be able to bin your scans and create a timeseries that "shares" data in a window as it evolves, you should scan in golden angle spirals.
I want an app that will let me do that spirally thing.

Thank you, finally this is explained easily! They always mention this in math classes and nature shows, and I've always seen this explanation of cutting golden rectangles into pieces forming a spiral that looks nothing like a flower, and then some sort of a half-assed explanation of, "see, you can form a spiral with the golden rectangle, so spirals in nature contain golden ratios and fibonacci sequences," always leaving me thinking the golden spiral looks nothing like the spirals in sunflowers, and that any rectangle can be cut into a spiral, thus a totally useless explantion.

Andy serkis talking about golden ratio is my favorite thing about this channel
We tend to think in decimals, that's why it seems so weird to us. But just by reinterpreting the value (here by presenting it by fractions within fractions) it suddenly makes much more sense. It's just there, it's natural and intuitive. We just don't use the perfectly intuitive number system. I wonder if there is one that would allow us to advance the mathematics faster, but I guess, we already have the knowledge to experiment on other systems and it has already been done for some time now,

Who named it the golden ratio?
I've just finished a sculpture design which relies on spirals consisting of sequential fibonacci numbers. It was a massive challenge because of the fact that the seed positions are so irrational. I got a bit of a shock when I figured out the lowest common denominator of 8,13 and 21! The completed sculpture will be worth the effort.
Maximum packing density and maximum space between each seed to distribute effectively.
any time there is a pressure field on evenly spaced or dense objects, it forces them into a golden ratio pattern. thtats why its visible from subatomic particles to galaxies. the entire universe is an infinite golden ratio fractal on all scales, caused by internal pressure.

Ben is my favourite contributor to this channel. All his videos are fantastic
Any way the flower seeds design emulator can be used publicly? Like through an app or downloaded or coded? I loved the way it represents any turn!
I have never found the golden ratio interesting before (hence not watching this video for over a year).
This status as the number that's worst approximated by any fraction, IE the most irrational number suddenly makes me care. Very cool.
I also absolutely love the relationship with root 2.
I have a pic of a sunflower that demonstrates the golden ratio extraordinarily well... Just looks really amazing. Started noticing the other flowers in that batch had some of that also.
Who named it the golden ratio?
Now I feel like I need to plant my garden in a Fibonacci spiral ♥
The golden rectangle as well :D
@@drippylad3973 Indeed!!! That's what I wound up doing ♥
Very well explained. It seems the seeds are most densely packed when they go around with this ratio. Nature knows how to maximise its efficiency! I forgot it was symbolized with a phi (capital or lower case?) and what its value was, but then it's not a number I have used for anything else other than as a curiosity to occasionally look up.
so basically, being irrational means being efficient, complex, and beautiful.
Want to try myself ! Any tips for using GeoGebra?
First time I've seen a use of continued infinite fraction that I remember. Cool.
Zhu Bajie check out the Mathologer video on contiued fractions if you liked this one.
THANK YOU for that snap frame, it made it a lot easier to stop on the frame to study it a bit
what a time to be alive!! thank you for this video, it actually helps my eyes understand what I been seeing...
I've been seeing the spirals but my eyes used to readjust focus (which hurts), but this model lets me know my eyes weren't broken
