Da Vinci's Vitruvian Man of math - James Earle 

Despite the depressing narration, da Vinci is awesome.

But what if he just wanted to draw a man doing jumping jacks?

I can't believe I never really knew what the Vitruvian man was all about. I thought it was just some kind of iconic study in anatomy and some natural ratios (artists do love their ratios). But, of course, Leonardo was thinking about much more than that.

Leonardo da Vinci learned anatomy from actual human dissections. He was given permission by hospitals in Florence and Milan. His drawings were so detailed that they can still be found in anatomy text books.

Squidward did a great job narrating this video

Leonardo: It's just a fucking doodle...

See, I wish someone had told me this sooner. I always assumed it was just a study in anatomy and proportion.

TED do a video on why we gravitate towards some voices (some narrators) while being put off by others please :)

I feel like they should've named the series Ted-ucate.

Fascinating facts about the Vitruvian man. Unrelated but also incredibly useful as an element of the sketch - Leonardo marked out his proportions for each section fairly clearly, making it a good template to learn how to proportion the human figure. My first year in art school we actually used the Vitruvian Man as a point of reference for this reason.

Thank you, Mr. James. Wonderful explanation of one of the greatest works.

Had a wild, intense dream several months ago, where I saw the Vitruvian man image drawn big on my bedroom wall in red, and I felt connected to the whole universe, to everything, for about 7 seconds. I had nothing but unconditional love flowing through me. It was like a feeling of true power. I guess some of the explanations in this video explains the meaning behind my dream. The use of free will to learn about love, to grow and flow in the opposite direction of evil. The choice is ours. Nothing to do with religion (of which I am not any part of). I know that this experience had to have meant something powerful, because the Vitruvian man image is completely random to me and something I don't even think about. It was totally out of left field.

The content was fine but you sound so bored I almost fell asleep myself

"It's a simple pen and ink drawing right?" Yeah, it pretty much i---"WRONG".

I was wondering what the Vitruvian Man was about so it was a good thing to come across this, thank you.

Interesting topic bad narrator

Thanks Ted Ed. You're right, these are lessons worth sharing.

We're your biggest fans, James! Thank you so much for the hard work you put into this amazing Lesson. We encourage everyone to check out his channel for more great content.

When he asked the first question and answered "wrong" I felt offended somehow 😂

This is the most informative three minute timespan I've ever experienced.

Watch the Numberphile Video on Squaring the Circle. It's explained well there.

RU-vid at its best.. showing only the best things in recommend .

I have the Vitruvian man on tapestry. Love it. Love Leonardo Da Vinci. So accomplished.

awesome video... I always wanted to know what was so special about this painting and now mind=blown

If my voice isn't too boring for you, I have more art history videos on my channel similar to this.

Man can crawl down the chain and become like animals (shows criminal act) or can crawl up the chain and become like God (shows charity) That's great evangelism ❤️

Wonderfully thought out ,outstandingly well shown through sights and so bewitchingly told !!!

Thank you I’ve often pondered about that sketch. Now I understand kinda!

Its just a simple ink drawing r- *Wrong*

Do one on Golden Ratio

thanks for the video, very well made

Beautifully explained, thank you!

Beautifully done, sir. Thank you.

When nothing's going right in your life but you watch these videos and feel that there's still more to life.

Wow this was really enlightening. I knew the drawing comprised mathematical properties (phi), but I didn't know the philosophical background.

Explanation on point.

I'll never see the vitruvian man on the 1euro coin in the same way1

Ted-Ed videos can be created by anyone, willing to share their knowledge. Rather than bitching about narration, please support the creation. This will be a moral boost for others too. These videos do not have to be James Bond movies.

This was deeper than I had thought of.

Nicely done, James Earle. (In my college days, back in the 1960s, one of my favorite Engineering professors was named James (or "Jim") Earle. He was a great cartoonist, and drew a regular cartoon for the University newspaper.)

I just saw this image of a man within a square and a circle without knowing its meaning.......now........... mind blown.

for everyone wondering, yes he's a teacher, and happens to be my english teacher. all of you should avoid making these rude comments since you know nothing about him. he's a wonderful teacher, and despite his monotone voice he makes his lessons very intriguing. i always leave the class having learned something new. instead of speculating over how he "delivers" his lessons, you should learn how to be a kinder person. if you have nothing nice to say, don't say it at all. stop making fun of him, because you don't know how much your comments might hurt.

Nicely made, Sweet and simple I like it.

Thanks for letting us know there is more! I immediately subscribed to your channel.

Squaring a circle is perfectly possible. Take a square with side length square root of π, and a circle of radius 1. πx(1squared) is just π. And root π times root π is also π. QED.

That was excellent and I just came from another Leonardo video (see below link) where they went further with its proportions and chambers of the Great Pyramid and spiritual energy, etc. For myself, about Humans "Being" in the center and able to move up and down the chain; it has great meaning to me. Since my awakening and experiences of "multidimensional'" realms and Selves and such things; this makes great sense to how they thought or what they knew and did themselves; Leonardo, the other guy in the video and the ancients. Spirit-Science is physical and non physical, its sacred math, vibration, sound and light frequencies and overall its the Macro in the Micro and vice versa. For myself, I dont always know the details, math and so on, but I do know from experiences how things are and work to great extents. Like a guy says in another video I will leave for all you who feel it and get inspired, "Wayseers have an unexplainable knack for just knowing the Way. They sense it in their very being. They can't tell you why or how they arrived at the right answer. They just know it in their core. They can't show their work. So don't ask. Their minds simply resonate with the Way. When the Way is present, so are they." Anyway when Humans have their own experiences inner and outer, here and beyond, their will be no more "hidden/coded" anything and new terms will be the norm, like energy centers, multi-d, Star Beings, densities, dimensions-consciousness and so on. Enjoy the two vids below and lots of love to you all. Love Christopher

Ok kinda off topic but Sometimes I feel like I know to much yet I still watch these kind of videos...

thnk u sir it was very informative.

The narration is really not that bad. When one person commented that, 500 others followed suit.

The concept of pie in formula of circle being indeterminate tells us why suare cannot equal a circle

This is why I like TedEd's Vids it has "Simplicity".

I love what you guys do ! :)

These lessons are so interesting sometimes I forget to give a like😭

Jimmy Hendrix used this picture in one of his albums, this could lead to another question, what would Leonardo have thought of Jimmy's guitar playing?

Thanks, James! A little enlightenment for me(and I’m sure, a few others.) Fun!

I like the narration.

*Looks like I'm not the the only one bored with my job*

"wrong!" At 0:25 is so funny idk why

I once drew a picture which I felt symbolized life, the universe and everything quite nicely. It was of a samwich eating a smaller samwich. ...am I famous now?

Quão bom é meditar em pessoas boas e coisas boas!

The narrator voice kinda reminded me of Joey Tribbiani's award accepting speech. Not interested to do it, but is doing it anyway.

BROTHER you narrate so fast .

loved the video, more than any other Ted-Ed video......

In the era with so less to offer these people gave so much for us!!!

I like Addison Anderson's narration more :/

Well this is interesting.

Great video. Thanks!

Excellent, you guys! Beautifully and splendidly explained 👏❤!! Gregg Oreo long Beach Ca

I'm from Italy

Its a long and very optimistic stretch to think he draw it to combine math, philosophical, religion and architecture into one. a very long streeeeeetch imo.

This was a brilliant video!

i liked your narration

Man talk slowly... Damn it!!!!

a picture does speak a thousand words,so next time don't ask "how do we use math in real life" ,we don't use it,it is the language of the universe... Leornardo is a polymath indeed

Vitruvian man was first described by a hatch ranking officer in Caesars army-Vetruvius. He listed those attributes that would make the perfect man. Including the naval and circle, and the outstretched arms equaling the height of a man. He listed approximately 20 different attributes. Leading up to DaVinci, there were several poor attempts at illustrating the list. DaVinci was the closest accomplishing that feat.

The way it was layed out it is a perfect proportional man.

The drawing is perfect except for the absence of underwear.

did anyone else cringe when the compass was placed on the naval?!

Formula for man's forearm is: (height in meters : root 3,645) :2 = forearm in meters Forearm measurement is from elbow to the longest finger

Great explanation !

I don't like this narrator...

Why is the narrator so depressed, someone needs to pay him more 😂

It's amazing video because It contains a lot of impressive and useful information

Stories worth sharing indeed

I feel like its a symbol from a 4th dimension.. time. You see different versions of yourself like trying to make a stick man walk or run through a series of flipping pages..

Boring narrator But the content is great

Mind blown, thanks...

the idea behind this picture interests me so much.

This narrator is so bad.

Da Vincky?

Great video!

I liked the narration.

Maybe he just drew it for no purpose :)

n u d e d u d e

Short but brilliant ❤️

why this excellent video has less like???it deserve more view and like than other videos of this channel.

they depicted God as a woman :)

What if this nigga Leo just drew some naked dude in a box with a circle just because he had been sipping on lean all day. I mean i do shit like this all the time when im hammered, perhaps ill save some of my work and years later ill get the recognition i deserve!

this is amazing!

A rational explanation, thanks for sharing it with us.
