Wow... Got given a programming problem to solve looking at fibonacci's sequence, read the equation and could not see where the hell it came from. Spotting something about "The golden ratio", I decided to go searching for that, which in turn led me here... How the hell can such a simple idea of having a line with the ratio of "a to b" being the same as "a+b to a" produce something so fricking awesome!? Mind officially blown. Thanks muchly ;)
This is great! I'm frustrated though that math is being dumbed down in public school. Like the math in this video isn't that complex, but when I show it to my teacher in ninth grade HONORS its treated like some kind of disease and I'm being told that it's too "hard" to do in class. Like seriously we should be allowed to learn at our own pace and not be put down to learn simple formulas that we've learned in the sixth grade!

The Golden ratio is also found the our DNA helix, the bronchial tree structure of the lung, the heart valves, etc..... This is not just a ratio... It is nature's ratio. Very intriguing indeed.
Sal I love how excited you get about math and concepts like this. I feel like these things can be mind-blowing and it's so cool to have someone to share this with, even if it's just me at home watching your videos. So proud of everything Khan Academy has become
Very straight forward. Just look at the basic definition: φ = a/b. Thus if a = 10, φ = 10/b = 1.618, or b = 10/φ And that is even more fun if you remember that 1/φ = φ - 1, so you can do that in your head. φ - 1 = 0.618 times 10 = 6.18 units (cm for this case) So side A = 10, side B = 6.18... GREAT video!! PS, obviously I'm only using the first 3 digits of φ for calculations.
Having never studied them myself, I have to take Discovery Channel's word for it that the Golden Ratio was used extensively in ancient architecture; the Parthenon being one of them. Also as I understand it, there are a great number of archways with this ratio measuring from base to sides and up to just where it terminates with the arch its self. It’s also in the windows of some churches. (as I understand it)
I read 1/2 of the book about the golden ratio by Mario Livio, I gave up on it because I wasn't really grasping all that was said, but this video really cleared things up, I'll probably head back into it now, thanks so much for your time and effort, the way you use colors and simple explanations is very helpful and clear.
Cool timing for this video. I am preparing to build a door to my house, and was considering incorporating the golden ratio into the design for fun. You've explained some things here that I didn't know about it. Thanks!
I personally found this video very confusing. It didn't really explain what phi was in the beginning of the video and went right into some equation that was afterwards explained as the golden ratio. I was beyond confused. I also would like to see that the work is more organized, it looks like its written it all over the place.
you could go this way as well: a^2 -ba -b^2 = 0 and solve for a, choosing the positive answer: a= b(1+sqrt(5))/2. Then use this in a/b and get the golden ratio as (1+sqrt(5))/2
Because that is what the golden ratio is. 2 numbers in this ratio added together, divided by the bigger one, exactly equals the bigger one. Spend some time with it to understand it. The golden number, 1.6180339.... is the only number that you can square by adding 1, and find the reciprocal by subtracting 1. a over a does =1. b over a =.6180339, those added = golden number. To make the ratio to any desired accuracy, you can add any 2 numbers, add that result to th previous, and the more times>
Sal - I seem to recall the golden ratio has something to do with the sub-linear implementation of Fibonacci in programming. I never took the time to learn it. I'd love it if you can make a video about how to calculate Fibonacci numbers is sub-linear time based upon this. Awesome Video! Thanks!

>you do that, the more exactly 2 consecutive numbers will = phi. Ex: 1+2=3;2+3=5; 3+5=8; 5+8=13--and so on. The more u do that the more accurately the ratio of the last 2 numbers will = phi. Try it. If you do it around 20 times it will be to the accuracy of an 8 digit calculator. The fascination things about th ratio are endless.
shapes make it easier, single pointedness 1, eye or flame 2, triangle 3, square 4, pentagon 5, hexagon 6 ect all these shapes hold the triangle in them, and is easier to see when 3d :) its metatrons art and language of numbers :)
Pretty simple, since we know that phi^2 = phi + 1. then we multiply both sides by phi and we get: phi^3 = phi^2 + phi but we already know that phi^2 = phi + 1, so: phi^3 = phi + 1 + phi phi^3 = 2phi + 1
The number 4 is always used in the quadratic formula :) If you're still confused, just google the quadratic formula and plug the values in for a, b, and c.
φ² = φ + 1 φ = (√φ)² φ² = (√φ)² + 1² this is the Golden triangle (Kepler's triangle), written in Pythagorean form, so it is a right angle triangle, which hypotenuse is φ. By the way from here and the unit square we can see the connection between φ and the REAL VALUE of π. Thus π = 4 : √φ = 3.144...
@theterabyte Maybe you mean the fact that the quotient of two adjacent fibonacci number converges to the golden ratio? (quotient of 89/55 (10th/9th fib.nbr.) already is 1.618). You can use this fact in a way like this: f(n) = floor(phi^n / sqrt(5) + 1/2). btw. you can start with any two integers and apply the fibonacci algorithm and the quotient will still converge to the golden ratio! It really is somehow magical ;)
the number of solutions is the mass results of a ratio, which means the effort using numbers is more relative and has its educating spiral, if this inteligence itself is a manifestation, its the number of the golden ration, which makes the fibonacci numbers interesting, the missing fibonacci numbers are the skipped sections to speed up patterns :) this phi number is 3 if its cycling, trinity :P triangle is in any shape ;)
@Jeorney Dude, it's not that mystery actually. Since, 2cos(Pi/5) = 2cos(36deg) = Phi 666 = 36deg x 18.5 or you increase your circumference distance a multiple of 36 degree 6*6*6 = 36deg x 6 (same analogy) As a result, the sine and cosine of evil number will be associate with Phi. However, it's very cool and flashy when you got the number from the calculator ;-)
Nice lecture. The number of nuture itself ! I always feel strange when i hear greek words or letters pronounced in this weirdo english way... Fie and pie :| Its just φ=fi and π=pi
If this interests you at all, look up Metatron's Cube and the Flower of Life. It's almost scary how the Universe's patterns have been known for a while now.
Have you also noticed that u can raise phi to any positive odd integer power, find the reciprocal, and that equals the decimal part of the number. Example: 1/phi^1=1.618033....minus 1. (naturally!) But notice that 1/phi^7 exactly equals the decimal portion of phi^7. Hallelujah! Also one can find a (little more complicated) similar relationship with phi raised to even positive integer values, but i leave that to you.
I will always laugh how teachers always had a terrible answer for how math was ever going to be used in real life. Always "how u gonna calculate interest or be architect or something" not "look at a pinecone, if you count the points, it's the fibonacci sequence. Math is nature, its everywhere"
Thanks Sal! This is a really great video. But is it possible that you could not rely on colors so much? I think I speak on behalf of your colorblind audience when I say that it's quite difficult to notice when a line starts and ends. Once again, awesome video :)
I am only 3 minutes into this lesson but I am stopping the video here as I want to savor it. I think this video combined with Donald Duck in Mathemagical Land could easily account for a good creative semester!

yes. it is the result of Fibonacci numbers being added to the previous numeral in the sequence. then dividing it

This video is so elegant!
This isn't only amazing to mathematicians, it's amazing towards everyone!
Pretty simple, since we know that phi^2 = phi + 1.
then we multiply both sides by phi and we get:
phi^3 = phi^2 + phi
but we already know that phi^2 = phi + 1, so:
phi^3 = phi + 1 + phi
phi^3 = 2phi + 1
This is awesome... I saw the same thing in wiki and I didnt get it until I watched this.

Maybe you mean the fact that the quotient of two adjacent fibonacci number converges to the golden ratio? (quotient of 89/55 (10th/9th fib.nbr.) already is 1.618). You can use this fact in a way like this: f(n) = floor(phi^n / sqrt(5) + 1/2).
btw. you can start with any two integers and apply the fibonacci algorithm and the quotient will still converge to the golden ratio! It really is somehow magical ;)
Genius, damn you have so much knowledge.
A cool way to find phi with any starting number other than 1.
Let: x be a number not equal to 1.

@Jeorney Dude, it's not that mystery actually. Since, 2cos(Pi/5) = 2cos(36deg) = Phi
666 = 36deg x 18.5 or you increase your circumference distance a multiple of 36 degree
6*6*6 = 36deg x 6 (same analogy)
As a result, the sine and cosine of evil number will be associate with Phi. However, it's very cool and flashy when you got the number from the calculator ;-)
this helped me so much thank you
I will have to watch this again sir.. too much information like this makes my head hurt and makes me cry sometimes
What mic do you use? It's amazing.
Thanks 😀
GENIUS AT WORK !! :D
Thanks !!!
THIS GUY IS BOSS
Nice lecture. The number of nuture itself ! I always feel strange when i hear greek words or letters pronounced in this weirdo english way... Fie and pie :| Its just φ=fi and π=pi
You're suggesting that we know of a propper way to pronounce them?
actually it sounds like π = pee and φ = fee. Its just that natives will always notice the differences :p
If this interests you at all, look up Metatron's Cube and the Flower of Life. It's almost scary how the Universe's patterns have been known for a while now.
Beautiful ❤️ mathematics
Have you also noticed that u can raise phi to any positive odd integer power, find the reciprocal, and that equals the decimal part of the number. Example: 1/phi^1=1.618033....minus 1. (naturally!) But notice that 1/phi^7 exactly equals the decimal portion of phi^7. Hallelujah!
Also one can find a (little more complicated) similar relationship with phi raised to even positive integer values, but i leave that to you.
Thank you so much!
Mind= AMAZED
I will always laugh how teachers always had a terrible answer for how math was ever going to be used in real life. Always "how u gonna calculate interest or be architect or something" not "look at a pinecone, if you count the points, it's the fibonacci sequence. Math is nature, its everywhere"
The best! :) I liked it :)
Thanks for the explanation! Really nice video!
Thanks Sal! This is a really great video. But is it possible that you could not rely on colors so much? I think I speak on behalf of your colorblind audience when I say that it's quite difficult to notice when a line starts and ends. Once again, awesome video :)
Awesome video
I am only 3 minutes into this lesson but I am stopping the video here as I want to savor it. I think this video combined with Donald Duck in Mathemagical Land could easily account for a good creative semester!
Thanks. Succinct and entertaining, and understandable.
Recursive and phi is so cursive looking. Once again my mind is blown
love it, thx
