The Golden Ratio in 1150

[SHAWNWILD1]

Listen to this CodySchuyler, people with his "I don't give a fuck attitude for the value of human life" is absolutely unreal to level that everyone grows up desensitized and feels nothing for anyone, but when it comes down to it, they would selfishly save their own asses at the cost of someone else's. The simple answer to this is that good ol' Cody here is living in the egoic mind of duality-consciousness and needs to be living from the heart in UNITY-CONSCIOUSNESS, Watch Drunvalo Melchizedek

[XKLUSIF]

why do u think usa keeps attacking arab nations. the US does not want these people to foil their plot for the new world order.

[PUFFTHEMAGICMARMOT]

We are in the midst of a dark age in the west, it's just that we still have Iphones. The greeks were clear about the fact that they got their mathematical knowledge from the Egyptians, who also built structures beyond the capability of modern construction, so this knowledge has been passed on, probably from whatever created us. We tamper with genetics all the time, and could even impregnate a virgin... kind of makes you think. Or not?

[luvphysics2009]

To say that Greek mathematical knowledge came from the Egyptians is an incredible overstatement. The Greeks had a culture that valued creation of new knowledge, while for all their thousand plus years of rule, the Egyptians could find the volume of a pyramid, the area of a plot of land, make a right angle using the 3-4-5 triangle, and work in a limited way with fractions (but only those with a numerator of 1). Read their description of how to calculate and it's clear they didn't generalize.

[industrialsparky]

thank you for these videos, I'm learning alot!

[GeorgiosMICHALAKIS]

After having uploade a video containing music played by a synthesizer using GOLDEN RATIO  intervals, and decided to view this video: it's EXCELLENT! The language is nice and clear, and it brought back to my high school years. Many thanks to the teacher!

[mamaleone1]

I'm so glad I found this channel. It's great!

[oirambarr]

Tks!

[Lamp1n]

hmmm okay.. i'm very curious in this subject matter. I'm not very good with math. What does this all mean in simple terms?

[arthurbulan]

His face is so cartoony

[raoulhery]

@arthurbulan so true

[granuladet]

as a muslim. this period we have a lot of problem. my people cannot think about science and technology. because of everyday peoples thinks about money to look after their family.this capitalist system wants people like machine. no religion no science nothing. this is also western world too.they earn money and going pub drink alchol think about sex. ı saw it. education system is sucks.

[russellmantz]

How did you get that from this

[raoulhery]

such a waste because back in the past, arabs were the greatest matematicians

[klauwn17]

@raoulhery

yeah that's why we use arabian numbers. modern science is based on old muslim knowledge in many ways. especially medicine.

They were already doing operations on inner organs while the europeans didn't even know how to eat healthy.

[Wrath0fKhan]

You are talking nonsense, granuladet...

[infoherper]

@granuladet nonsense, your just too retarded to think about sicnece and technology. And im talking about you, as an individual because Muslim people still continue, as they have been, to make contributions to math and sicence. YOU are just too ignorant to care so you bullshit other people. Am I correct?

[TomBrooklyn]

@infoherper As an angry and vehement defender of Islam, are you a practitioner of the Jihad--and what the Western Infidels would call a terrorist?

[infoherper]

@TomBrooklyn No, I'm not. I'm an American and a far better one than you at that, you fucking redneck. This is the fucking reason we're in deep fucking shit. Because of rednecks like you. You know how I know your a redneck troll? Because your making a big ass religious affair on a video about an irrational mathematical constant. Now haul your ass back off to at least the second fucking grade.

[codyschuyler]

@infoherper i didnt know we were "in deep fucking shit", i thought we were fighting some farmers in the middle east not a superpower like russia

[infoherper]

@codyschuyler Where've you been? Last time I checked, I saw a shitload of national debt, our troops dying in the Middle East, and Bush taking a shit on the U.S. during his years in the office. And that's just scratching the surface of all our problems.

[codyschuyler]

@infoherper the war has nothing to do with the debt, infact the war is helping the economy by creating jobs and we are kicking their ass's, we only loose like 200 troops a year compared to them loosing a thousand each year.

[infoherper]

@codyschuyler Yeah but that's 200 too many

[enter08com]

Too simple... 1*!

[nillawafer96]

how is 5squareroot 5 equal the squre root of 125?

[1Mperios]

5 = sqrt 25

sqrt (25 x 5) = sqrt 125

[ladicius]

you break up the root125 into root25 x root5

whats the root of 25? (5)

root5 is simplified.

so 5(root5)= root125

[Kurtlane]

Why couldn't al-Samawal do what you just did here?

It's so simple.

[a1a2a2qwer]

@Kurtlane

it's the same thing just simplified lmao. and who said he couldn't?

not doing something doesn't mean you can't lol.

[jazzguitarlessonsnet]

Great teaching. Nicely paced. Thank you.

[FalseDirection]

your a great teacher .. Keep it Up !

[FahadKhan1988]

For more information, google: Islamic Golden Age

Thank you

[leporidus]

Around 8001100 CE, the intellectual center of the world was Baghdad. Neil deGrasse Tyson has given a great talk about this "particularly fertile period":

v=JQoLbPudHTE

"But in the 12th Century, disaster struck. Imam Hamid al-Ghazali declared that mathematics was the work of the devil, and he rejected rationalism and naturalism as valid ways to understand the world.

Revelation replaced investigation.

The intellectual foundation of Islam collapsed [...], and it has not recovered since."

[2daysNews]

simple algebra...

[arthritismutilans]

An unfair maths algebra question in one of the scholarship exams asked,

Prove that the cube gives the greatest volume to surface area ratio of all 6 sided rectangular/ square hedrons. Can you help

[44Beats]

he only lost me when he factored the 2's at the end. how did 4 divided by 2 became 2.2? was it because the division of the numerator was not 2 but 2 +2 square root 5? WTF how did i lose it on the last calculation?

[cameronc76504]

it is not 2.2 it was 2*2  which 2*2=4

[dcedilotte]

2.2 is actually 2 x 2 it's another way to write multiplications.

[thejodesta]

Wow i actually remember that process. My dad use to go on and on just like this guy did on the white board. I remember my dad doing similar stuff when i was in year 9.

[radiatr99]

nice! :D

[zacko325]

This is crazy but im sure ill learn someday i dont know wat he just said.

[sataviah93]

I did not understand a word he just said, but I am determined to learn more about radicals. I wish he was my teacher when I went to school.

[vladika07]

Another way is to start with the sequence (Fibonnaci) 1,1,2,3,5,8,13 21 etc - the next number would be the sum of the last two etc (34) Divide the larger number by the smaller one and you get the golden ratio (21/13 = 1.61) This sequence is sometimes called the fingerprint of god. It is used in architecture and our bodies are built like that and so is the nature and cosmos

[McrueProductions]

did not under stand a single word. but when watching this on my wide screen monitor i noticed you tube is also a golden mean when scrolled to the top

[UroborosComplex]

you are freaking awesome! I hope one day I can be as good as you!

[Darkgravx12]

HUMAN DNA III Principals of immortality by Dan Winter 1

also has to do with the golden mean, how nature is perfect. might even have u believe in god by learning about this lol.

good channel, this MathTV, too bad kids dont watch this, would learn a lot

[rs2calc]

I thought the golden ratio had something to do with rectangles

[DICKDICKASSVAGHOLE]

i can be, it can also be triangles, or plants, or dna, or the human body or a whole whack of other things

[0103303]

wow~ 역시 수학은 재밌어

[LTF85199]

I am anxiously awaiting differential equations tutorial -your faithful subscriber

[ICgraFX]

I love your clips and you are great. I guess there would be no problems if there were more teachers like you. I wish you and your project the very best and hope that many people can see that math isn't meant to be anything but a nice way to describe everything.

[irfaanfr]

Islamic mathematician!!

[kenbatosai]

Its due to Muslim mathematicians and scholars that Europe witnessed Renaissance. Muslims developed on the knowledge of Greeks theologians in essence preserving it when Europe was in dark ages.

[kk2death]

@kenbatosai but remember that Mesopotamian Civilization is older than ancient Greek .

[adeadlysniper]

Yeah from about 800-1100 AD Baghdad was the intellectual capital of the world. If you look at the names of observable stars in the night sky, many have Arabic names. The word "algebra" is in fact arabic as well, since algebra was invented around that time period.

Funny, though, since today it has shifted 180 degrees; the Islamic middle east is now the intellectual black hole of the world, considering how developed the countries are. It's so sad that new ideas in these countries are suppressed.

[ednakazuya12]

@adeadlysniper You don't mind asking you weird question?

[missionaryoffaith]

@adeadlysniper

sometime new ideas come to greed as well so it might be a very fine line

[DjDedan]

@adeadlysniper aren't our numbers arabic as well???

[jmaioran]

@DjDedan Actually, our numbers are indian, not arabic. A fun documentary is (and you watch it online.. google it), The story of one by terry jones. Indian numbers travelled to the middle east sometime around 980 ad which is when al-gebra .. happened. The indians were pretty clever back then, and in fact invented the number zero also.

[DjDedan]

@jmaioran ah i see, cool... mayans also figured zero as well i thought??? i'll check the documentary as well - thanks!

[IBMua]

@adeadlysniper It's all about religion.

[FlaiteOne]

@IBMua its all about the elite mantaining us in ignorance, in fact the bible as an example, posseses the golden ratio expressed in many versicles for example in the lenghts of noah's ark, so the word of god wants us to know all of this...

[longanddeadly]

@adeadlysniper problem is too many people dont give a shit ...also information and new ideas are suppressed everywhere around the world, just in different ways.

[G0ttaBeFresh]

@adeadlysniper I think there is a reversal taking place lol. America used to be number 1 for education, science, math and engineering. Now developing countries are beating the shit out of us.

[Teh48Finn]

wow i can't believe he was right, when did we figure this out?

[bobbysmilesok]

honk honk, what a donk

[greger333]

... instead of actually talking about the golden ratio and all its wonderful properties, he spend 4 minutes on a trivial simplification.

totally worthless

[beornborg]

Since this ratio was found independently, it reinforces the value of the golden ratio.

[greger333]

but still, it has nothing to do with the actual number. nothing about partial fractions, rabbits behaviour and so on. u

[snakeguy76]

this is actually a continuation (sort of). he does talk about the golden ratio in other videos

[Alfaris]

this guy posts videos for those that need to hone their math skills or for those that are just interested in math. If the viewer was interested, the viewer would've researched the golden ration on his own. Besides, he said he might do a video about it later.

[beornborg]

There's only so much he can show in one short video. You may want to consider reading a book or a longer form video from The Teaching Company.

[rogermoore27]

this is fantastic. I never knew I would enjoy Math before this video.

[fistylo]

i smile because i feel that american people don't know anything about for example Al-Khawarizmi.

[zahidayar]

thanks 4 the video :) it was very enlightening

[CousinoMacul]

Rationalizing the denominator by multiplying by the conjugate is really a neat trick.

[zahidayar]

yes, its a cool way to simplify an expression
