This video about Fibonacci numbers was as good as the last two combined!
not going to like because likes are at a fibonacci number
Underrated comment
It is so interesting how literally everything in math is connected and intertwined. This is really cool because if you don’t quite understand a certain topic or problem you can look at some things you do understand and connect it to what you are having trouble with.
That is the essence of what is known as the Langlands Program, named for Robert Langlands, who essentially created the whole schema...it relates to what are two entirely separate fields in mathematics, harmonic analysis and number theory, and the bridge that links them together.
EXACTLY! I also find fascinating how this figure is encoded in math and anywhere you go in the universe, the figure is still the same!
Kudos to the animator. The scuttling mandelbug was a delight.
David Wiley The sound and the animation cracked me up.
No it was in fact the very opposite of a delight .
Yusss. I came down here to find the comments about it. That made me so happy. 4:24
It's a Miyazaki Mandelbug!
It's a Scuttlebug jamboree.

Muhammad Mamoon 2+2 is 4, -1 is 3, quick maths
Well, you have the basics down.
Who thinks that’s funny?!!
Every time I’m feeling particularly sharp or intelligent, I click on one of these videos and it instantly puts me back in my place 😅
Still, for my limited understanding in advanced math, it was quite interesting.
7:20 Sometimes called the "naive sum" as well. It's also how you construct the Stern-Brocot tree, which enumerates all the positive rational numbers without repeating any.
Wow mind *BLOWN,* this is amazing
Who else just wanted it to keep on zooming in until infinity? [8:41]
You mean an infinitely long UA-cam video? No thanks.
Yeah. I wish it would've just kept doing numbers and faded out, to create the impression it could go on forever. Stopping makes it look like it fails at that number.
Nobody with half a brain thought it "failed" at that number

Everything about this video was great! The visuals were tuned perfectly. The explanation was thorough but succinct. And the enthusiasm of the presenter really brings it all together. Great work!
It's pretty cool, that these two things have such a connection
But not terribly surprising, Fibonacci numbers pop up just about anywhere.

@@albertb8999 I see what you did there, incorporating the sequence into your sentences.
Well played, Albert B, well played.
I used to hate Mathematics. Long story short I developed Arithmophobia since an early age. Until tonight I watched a video about Fibonacci Sequence that introduces me a total new prospective of Math into my life. And for the first time in a long time 33 years more or less (I'm actually 37) I understood Mathematics 😱🤯😍 And after that I found this video is like a double 🤯🤯 sorry I had to is literally mindblowing. I think I can start saying I HAD Arithmophobia. Thank you!
I would 'guess'? it usually happens because of how cumbersome it is to get used to it from such a young age and to basically drill math into your skull by brute force.
Maybe, for whatever reason you had a knack for math but never developed the skill to use it because of some bad experience learning it growing up, at a very critical time. But this here, this makes no sense. It's like finding a glitch in the matrix. That's why it's so fun.
The beauty of this math overwhelms me with emotion. Perhaps that seems strange, but the beauty of how all this works out makes me want to cry.
I thought I was the only one who feels this way! I completely agree! There is just so much order and beauty in all the world I don’t know how to take it all in emotionally.

What do you mean wrong, the limit of the nonconvergent sum of 1+2+3+4+5...+n where n=Alephnull-1 Does end up as -1*(1/12)
jawad mansoor YOU CANT JUST MAKE THAT CLAIM AND LEAVE
+jawad mansoor Riemann has done much more besides his hypothesis eg: introduced the term manifolds, riemann integrals, was one of the pioneers of non euclidian geometry (with gauss and some other russian guy), also physics and probably tons of things that im not aware of, he was one of the best mathematicians to ever live
Test question: In the Fibonacci sequence 1, 1, 2, 3, 5, 8, 13, what would be the next number?
Answer: So you take a point called c on the complex plane...
So is not a valid word with which to start a sentence except in very rare circumstances, for example explaining the purpose of doing something.
@@philpayton8965 It is valid for a joke though. The joke was that he's explaining a very easy concept in the most complex way imaginable using the most casual language possible.
@@nodezsh sorry man it was a bit pedantic of me it just used to be a pet hate of mine, probably fuelled by the fact I had a horrible micro-managing supervisor who started every sentence with "So...".
it was a me problem, not a you problem, just ignore me. was a long time ago now anyway.
Despite being quite familiar with both the Fibonacci sequence and the Mandelbrot set, my mind was indeed blown. It's even more amazing how "number games" like this can relate to the physical world (at least the one we can perceive).

This is one of the very best layouts of this fractal relationship with the Fibonacci sequence
Thanks for the incredibly fascinating video. The more I learn about the Mandelbrot set, the more I like it. Dr. Krieger is excellent as always.
Amazing.... please do more videos about the Mandelbrot set. It is the most interesiting mathematical object I know of, in my opinion...
Loving your videos!
*The reason I love mathematics*
"Is the universe a fractal that can be calculated in equation?
Is it Fibonaccis perfect golden spiral or is it just my imagination?"
From what I can tell, the world is defined by mathematics and patterns naturally. Math is the translation for the patterns that took the chaos or the earliest known parts of the universe up till as far as we can see. When Mathematics fails is the day I'm lost lol. @@microbuilder
Beautiful Ladies teaching us?🤫
Peng broads?
I wrote a program to generate the Mandelbrot set many years ago and the interesting part was outside the iconic shape - the colours are formed as visual representations of the number of iterations (like a contour map) with the iconic shape merely the set of values that kept on iterating. They were the boring bit! Thank you for showing me what I was missing. I'll have to revisit that code with these extra features to explore!
These inserted animations make all the difference - great thinking mr Haran!
Glad you liked them - they were done by Pete McPartlan
Next: how to cut a cake via prime numbers, Graham's number created by Conway's game of life, and the fractal dimensions inside Parker squares.
Do you want existential crisises? Anyway, cool subjects!
…while doing a dice trick represented by playing cards printed on the surface of a Klein bottle.
Great explanation, thanks. By this construction the numerators are also the Fibonacci sequence, two terms behind the denominators. Since the ratio of subsequent terms in the Fibonacci sequences approaches the Golden Ratio as n --> infinity, this means that the ratios that you are considering approach the Reciprocal of the Golden Ratio, Squared. [I think this is right - and surely pretty well known. I just realized it from your presentation.]
This channel never ceases to amaze me.
Glad to see her again!
2:12 even non-mathematicians love this for different reasons xD
Shubham Shinde
Yes it is fun. They kind of look down on us as children.
When you really uncover it, it is for the same reasons, it is a way to describe or show the nature of the universe and consciousness. Just mathematicians see it in numbers and other people see it more spiritual, but it dissolves into the same sensations one has.
@@pizeblu well.. except that the way mathematicians see it actually makes sense, the way you see it doesn't.. it really have nothing to do with consciousness, the nature of the universe... It's just math
As a non matematician myself I love it because it shows how something so complex and weird can come up from such a simple rule.. also because fractals are just weird, counterintuitive and fascinating.. but nobody who understand this even a tiny bit would say that it's connected with things like consciousness or the nature of the universe.. get your feet on the ground mate
@@raffaelepiccini3405 I just don't understand how so many people who had never communicated before are able to "figure out" fractals and how they relate to consciousness on their own.
Very interesting and well explained Holly as always. Thank you!
Numberphile really nails it by explaining math in an entertaining and lighthearted way.
I can see that nail and gear flag in the background :)

I would tell a joke about Fibonacci.
But it's as bad as the two previous jokes you heard combined.

I just saw this live at the Cambridge maths open day. So cool!
This is amazing. I'm sure that somebody can show that this connection is absolutely natural. But it definitely is not obvious and that makes it so beautiful and funny. Thumbs up!
The Mandelbrot Set will never be as beautiful as Dr. Holly.
I disagree :Ü™
Love you Dr Holly!
You could draw a straight line from 1/4 to the waist. Since the map is 1/2-sqrt(1/4-z), the straight line from 1/4 is still straight in the circle. And an arc subtends half the angle from a point on the circumference that it does from the center. So the bearing of the point on the circle from 0 is the same as the bearing of the point on the cardioid from 1/4.
Elegant, beautiful illustration of how math describes our universe. And, how most everything is connected. Thanks for the deep sense of awe I'm feeling right no.

Mandelbrot set is amazing. It's incredible how quite simple definition leads to infinitively complex structure.
i was obsessed with the fibonacci sequence when i was little and i'm obsessed with the mandelbrot set now, seems like a perfect video for me lol
Not only is the maths in this really cool, but I also loved the cheeky Nail and Gear hiding in the background :)
Math is amazing. Who even discovers this stuff?!
Soumil Sahu mathematicians
+Cellkist obviously, but who goes out of their way to say, "today im gonna pull out the Fibonacci sequence out of a weird shape"
Soumil Sahu They don't. They explore a weird shape and say "Wow! Fibonacci sequence relates to it!"
How do they find the weird shape to being with? Well, mathematicians make random problems up and hope they lead to something interesting. The Mandelbrot set was a lucky discovery!
Soumil Sahu sometimes it's a Mathematician, sometimes a "non- Mathematician" notices a pattern and wants to know: "does this 'thing' ever stop or does it go on forever?" They may get bored of it, or keep studying it, or even become obsessed with it (especially if their pattern appears to present itself everywhere; it's a constant reminder.)
People who think it's amazing
So I guess it's time to fall in love again...

Hi
Ha ha ha - he may be a math geek and be on about that !
I love how Brady has the Nail & Gear in the background.
I was wondering if Farey sums would come up! I loved that other video on them, too. :)
Person: "what the heck happened to your mind?!"
Me: "oh dont worry it was just blown"
Hey, thanks as always
my mind is blown off right now.
I am amazed and mesmerised
almost ecstatic to find out the relation between Julia, Mendelbrot and Fibonacci
Thanks a lot
Gorgeous illuminating presentation :) thanks
You had me at Fibona..wow those eyes...
ik i dont understand what they are saying on numberphile but i still like to watch the videos
We also have the start of the Fibonacci numbers 0,1,1... in the complex plane. The zero in the centre can represent t=0 the moment of now in an individual reference frame. We also have negative 1 and positive 1 with a rotation 2π that is a constant represented by ħ=h/2π. Therefore we even have the start of the Fibonacci numbers 0,1,1,2,3,5,8,13,21... forming spiral on all levels of creation!
Mind blown. Again. These videos are so amazing.
Because we keep going between two fractions, does the fraction approach something?
trekky0623 I believe it approaches 1 - 1/φ, where φ is the golden ratio (1 + sqrt(5))/2.
So when do we get a zoom in at the golden ratio?
Approaches 1
zoom in infinitely and you will get the golden ratio.
But why should the Mandelbrot set have tendrils that coincide with their Fibonacci position?! I feel like I was told I’d get an answer and all I got was an amazing new mystery
Rick Weber Isn't that all what answers are?
That explanation just made me more confused. The explanation seems like an even crazier way for numbers to function.
Could you do a follow-up video on why the bulbs at those median points always have that number of antennas equal to the denominator?
Fractal sets and the Fibonacci sequence seem to be a base geography of our world. In this video you seem to show that the Fibonacci sequence auto-magically flows out of the Mandelbrot set. Extremely fascinating, thanks.

SHE BLINDED ME WITH SCIENCE!!
This is math, you’re even blinded by vocabulary.
Thomas Dolby......luv science
OK, I see the Fibonacci series in the hyperbolic components along your circular transformation, but I still don't understand what it has to do with the number of antenna branches. Did I miss that, or did you forget to explain it?
Just noticed that at 6:07, the hyperbolic component labeled as 1/5 is actually the 1/4 component and the next largest one the right is actually the 1/5 component.

Dr Holly Krieger and the Mandelbrot Set, name a more iconic duo... I'll wait.
Is this a reupload? I already knew Fibonacci could be found in the Mandelbrot set and I really feel like I learned it from this channel, also from Dr Krieger, around the same time as you made the videos about the Julia set? Maybe I'm just confused..
Either way great video as always ^^
edit: definitely a different video
*Brady always asks some great questions.* Correct me if im wrong but his qualifications are in engineering and not math(s)? He obviously has some math skills or at the very least a good math instinct, but how good are his actual math skills? Has he done any papers and if he has has he been cited much?
he is a journalist
Bengineer8 He is but im pretty sure ive heard before that he has a qualification in engineering. And most journalists dont know anything about maths. It got me wonderin
Dr. Haran really makes great questions
He is not a doctor.
Wise Guy he is indeed
Am I allowed to say that you look amazing and I just love to watch and hear you explaining very intelligent things I don't understand :-)
The sound of the marker pen gave me goosebumps
I'm watching this on high, sounds awesome
Math never ceases to amaze me.
I had a computer generate the Fibonacci sequence in college and at a certain window size, the arrangement of the numbers made that double spiral pattern you see in flowers. I've long forgotten the details but thought it was cool.
2:10, they found us
Interest in fractals from those sources did cause me to pursue the higher maths and actually learn a bunch of cooler things too in college. I don’t doubt a math focused documentary on visuals would contribute to greater interest in pure math.
This was very interesting and well presented 👍🏻
Gotta love that 9:59
A very simple and elegant explanation.
That was really well explained... thanks!
Ah, Dr. Krieger! Must be my lucky day!
@TheronQRamacharaka jeez chill haha
We should all be so lucky.
Nail and Gear!
What happens if you apply the digital root of the numbers in the fibonacci sequence instead?
(which happens to be a set of 24 repeating numbers? the first 12 being a 'reflection' of the second set of 12, where 1st and 13th (and therfore 25th and 38th), 2 and 14, 3 and 15 etc always add up to 9)
1-1-2-3-5-8-4-3-7-1-8-9- (1st to 12th Fibonacci numbers)
8-8-7-6-4-1-5-6-2-8-1-9 (13th to 24th)
Would you find that there is indeed a repeating cycle in the mandlebrot too?
That's what I call a satisfactory video. Simply beautiful.
gurl, you made me accutally understand it
But does 0 count as a fibonacci number?
By definition, the first two Fibonacci numbers are 0 and 1, and each remaining number is the sum of the previous two. Some sources omit the initial 0, instead beginning the sequence with two 1s
there are 2 definitions,one says that F1=1 F2=1,the other says that F0=0 F1=1 F2=1.But i don't think that F0 makes any impact,so it's usually omitted
In fact, there is an often-forgotten version of the Fibonacci sequence made up entirely of 0's. You start with 0 + 0 = 0, then you add the last two numbers together to get 0 + 0 = 0, then again, 0 + 0 = 0, and so on. You end up with a series (0, 0, 0, 0, 0, 0, 0, 0, 0...) that looks boring but is actually found all the time in nature. For example, once somebody ate all my cookies, so I had 0 cookies, but the weird thing is, the next day I still had 0 cookies, and then the next day 0, and then 0... cool, right? Who says maths has no application to real life?
Madder Sky; F0 = the inertial plane, before perturbation.
Can you imagine how blown away Fibonacci would be if he could see the Mandelbrot set...
Such an amazingly explained. liked it
0:45 What's up with the up-arrow-paper appearing in all the videos lately? Oh, and 7:32 should be 1/2 + 1/2 = 2/4.
MasterHigure, That's funny, do more arithmetic.
Freshman Sum Freshman Sum!
Baaahahahahahahahahajahahahahahahajajaja
I mean, you messed up a Freshman sum. That's basically a Parker freshman sum right there.
Yeah, you said that Freshman Sum was in a certain way and showed it differently.
So, where is zero component?
Krowwweee presumably 0/0ths the way 'round the circle. :)
NWRIBronco6 0/0ths is indeterminate form. I doesn't exists as any number or exists as all numbers. I think you mean 0th way around
Final Spartan I meant what I said and I said what I meant. Trace back the rotations to 0% and you'll find your Fib value still one in the norm. So I suggest, in jest, indeterminant form. :D
You see where things aren't, in the Mandelbrot set? It's right there.
0 is not included in the fibonacci sequence
I like how all these videos are done in sharpie on cardboard. It's a nice touch. Very satisfying, but I wonder how often they mess up?
Starting with 2/5 and moving against 1/2 I will find /7, /9, /11 and so on. Going clockwise moving against 1/3 I get /8, /11, /14 and so on.
It seems any fraction can be found, not only fibonacci fractions. It all depends on the direction pattern. The fib pattern is left, right, left,...
The pattern I found is just left all the time. Or right.
