Okay, so I'm going to explain in this video a math and design phenomena called the Golden Ratio. It's

also referred to as "Phi." So what is the Golden Ratio? Well, to help explain it, I'm

going to put out the sequence of numbers called the Fibonacci sequence, which is

really just the Golden Ratio in a sequenced, numeric form. Now to arrive

at this Golden Ratio sequence of numbers, we just need to follow a basic math

formula. And I'm not a math person, so we're just going to keep this very

simple. Okay, so you just start with 0+1=1. And now to get to the

next number in the sequence, you take the sum of that simple equation and add it

to the last number in the equation. So 1+1=2

and then 1+2 = 3. And it's around this point that the ratio

actually starts showing up. As we continue to do this formula, we start

arriving at a set of numbers: 2, 3, 5, 8... and you see what we're doing-- we're

adding the sum of the equation to the last number in the equation, and we

arrive at this sequence of numbers. It's interesting that this sequence and

ratio actually remains consistent no matter how long you follow this

mathematical formula. And so this sequence continues to expand outward

around the rate and the ratio of 1 to 1.6. Now to help give you an idea of what

a 1 to 1.6 ratio is compare it to a 1 to 1 ratio so to make a 1 to 1.6 ratio, you just

envision a little more than half of the initial line added to the line of the

other side. Alright so this ratio 1 to 1.6

This is the ratio that's called the Golden Ratio a 1 to 1.6 ratio. So this

is what the Golden Ratio looks like as a rectangle 1 to 1.6. And if we were to start

making incremental Golden Ratio points within that, we can get an idea of what a

spiral looks like when it expands outward at the same measured sequence.

Now this is all well and good, but what does that have to do with everyday life?

Well, a lot actually. And that's because when we look to nature, we see that so

many things flourish when they go to the golden ratio design and when they follow

this sequence. Growing and expanding to the rate of the golden ratio spiral

allows the maximum amount of rain to be directed down to the roots of many

plants. And remarkably when you study nature, you see the golden Fibonacci

numbers like 3, 5, 8, 13, all of that again and again in the seed patterns and spirals

of plants, as well as in the number of petals.

Next time you're bored and have a sunflower, try counting the number of

seeds in the sunflower spiral-- the Golden Ratio! Or maybe try something else with a

spiral, like a pinecone or pineapple. So we can spend all day counting the seeds

of flowers, and plants, and fruit... I mean, you get the idea. But we don't just see

this Golden Ratio sequence on a small scale. This ratio is the mathematical

sequence in the spirals of our storms. Tornadoes, hurricanes-- these all spin in

this golden sequence 1 to 1.6! Even the waves can be measured using this ratio.

But it doesn't stop there-- modern technology continues to be mystified by

the far-reaching scope of the Golden Ratio. From the alignment of the planets

to the spirals of our Milky Way galaxy, as well as the spirals of other ratios

of planets. Now let's take this closer to home, I

want you to hold out your arm and look at the distance between your

elbow to your fingertips is "1.6." Pretty crazy huh? but doesn't stop

there. Now take that further the distance from

Keep it going-- from the furthest tip of your finger to the

is "1.6." Now check out the spacing of your knuckles 1 to 1.6. Are you

teeth are so much bigger? Golden ratio! The pupils of your eyes-- I mean, you name

it, your whole body is the symphony of the Golden Ratio! In fact, as you are

listening to this video, the sound waves are passing through your ear in a

perfect golden spiral. Scientists have discovered that the golden ratio pattern

is necessary for the human brain, the neural system, our sense organs, and our

lung system. The golden ratio sequence is even in the helix of our DNA, and it

forms the very rhythm of our heartbeat pattern!

This is pretty amazing if you ask me! The universe is an incredible place, and to

think that these beautiful intricacies of the world all hang on a stacked, razor

edge with the incomprehensible fine-tuning of all these precise

constants and quantities which allow the universe to begin to exist.

I mean it's unfathomable! No wonder we are a naturally bent to worship a higher

creative power. I mean, we are fearfully and wonderfully made, and we live in a

universe that is designed and hardwired to be life permitting. And speaking of

which, I think it's interesting that the Golden Ratio also comes up in the

ancient Biblical texts. Scholars have noted that wouldn't you consider

design measurements of things like Noah's Ark and the Ark of the Covenant,

the Golden Ratio is an exact match to the measurements. Pretty interesting... Okay,

so we've seen how the Golden Ratio is embedded into our life and even into our

own heartbeat. So naturally, it's going to affect our aesthetics and the arts.

It is believed that the Greeks used the Golden Ratio to achieve ideal acoustics,

and many instruments are actually designed with the ratio. When you look at

the amount of black keys and white keys on a piano,

it should be no surprise that you see the Golden Ratio. And that's because

the musical scales and notes align with the Fibonacci sequence. So

scientists, mathematicians, and artisans have been aware of the Golden Ratio and

have been incorporating it into their architectural and artistic designs

throughout history. For some reason, designs tend to look better when

composed and designed with the Golden Ratio. Look at iconic ideal Greek temples

like the Parthenon in Athens-- you can see that they use the ratio again and again.

Painters have also been incorporating the golden ratio into their artistic

designs because it gives the composition a "je ne sais croix" ("I don't know what.") Leonardo da Vinci was

obsessed with it, so was Michelangelo. Even in the 20th

century, you see the ratio being used in painting-- whether it be in the dimensions

of the canvas, or the placement of the focal point. And by the way, the Golden

Ratio is one of the reasons artists don't like to line everything up in the

center. But you don't have to go to Greece or to the Louvre to appreciate

the Golden Ratio in human design. I mean, just look around your house or go to the

grocery store. The golden ratio is used in product

design, logos, and in branding all the time. It's a ratio that, for some reason,

is pleasing on the eye, and it can be a great template for solving multiple

design problems. I remember when I first started learning about the golden ratio,

I began to see it everywhere, and it's really remarkable with how it comes up

in nature and in the design world, and and how artists can greatly improve

sequence that pops up again and again, now go out, and I want to challenge you

to go and look and find places where you see this ratio. You don't necessarily

have to take around a measuring stick, but but take pictures, and

notice where you see this ratio come up in design and in nature. And I think you

will be surprised-- and perhaps, even, this newfound awareness it might even change
