- In this video I am talking about Euler's work in the Saint Petersburg academy, Euler's constant, integrals and prime number product formula !
I recommend reading "Leonhard Euler: The First St. Petersburg Years (1727-1741)" by RONALD CALINGER to learn more about Euler.
(00:00) - Intro
(00:23) - Bernoulli family and Euler
(01:00) - Euler's famous formulas
(03:07) - Intercept method in cartography
(04:45) - What almost killed Euler

I am planning a video about Poincaré that will also surprise you. Please support by subscribing !
Any idea what actually caused his blindness? I have heard that he was going insane later on in his life, maybe it was this period. But that doesn't mean he can go blind. And doing math definitely doesn't make someone go blind. I have a feeling he worked almost every hour of the day for days at a time and that might be the reason why.
Bravo
Yeah keep going. We appreciate your efforts man. :)
ok here is a challenge
bring me one evidence from which you can prove there was a man named euler
only primary evidences are eligible i.e papers and evidences that were present during the time of so called euler not those paper which claim of euler after he was dead for 500 years ago
good luck for your search you will find amazing things but one one primary evidence of euler
Complex mathematics: it’s all fun and games until someone loses an i.
😌 My species.
How does Euler’s identity fit into all of this?
@@antman7673 was that a pun too
Can you *imagine?*
I'd rather lose an i than an eye though. Aye?
just imagine if Euler was alive today, the things he could've done with computers
To be honest I don't think computers would have helped him much. He was already a genius which could do huge computation by head. But the internet would probably speared his work much faster.
42 likes .. don't break it guys
@ modern LCD computers don't damage your sight
Or he would all of his time playing games and watching videos.
@@ishdx9374 why?!
He traded his i for an e
I think you win the comment section.
well done. you have given the funny. here is your like
Shut up and take my like.
OMG! I feel enlightened now.
This comment should get its own wikipedia article!
So next time if I catch you complaining about your trig homework...
e
Hello sir. You opened my eyes to the world of maths 😂😂😂
I was just happening to be feeling guilty about taking it easy on my math when I read this
lol
@@bagochips1208 Yes that's a number.
another reason to not do school work , you might go blind ! checkmate euler
Throughout his adult life, Euler published 800 pages of maths papers a year.
What a genius!!
thats more than 2 papers a day.
@@doriannamjesnik3007 More than two pages per day.
I could count myself lucky if I made one in my lifetime lmao
Actually, he published 800 works over the course of his WHOLE LIFE.
I thought he was winking or squinting to try and see the complex plane.
I used to think the same !
*Legend*
5th dimension! :-)
Giving an eye for knowledge...like Odin. Pretty rad.
Lost my testicule for nothing 😡
This is what great men do.
Knowledge has not price...
It sounds like hell to have to do even one trig problem by hand, let alone hundreds of complex ones.
@@whannabi so
He also smoked a pipe constantly. He in general didn't have the greatest health but still contributed so much to mathematics. It's like an alien monolith.
Makes me wonder if he suffered from tooth-ache, and the infection (fever) spread to his optical nerve.
I think I'll take up pipe-smoking...
His eye became imaginary.
But jokes aside, what an absolute legend of a man.
So his eye became i?
@@ThePC007 explaining jokes isn't funny

2:33 "...and each prize was worth around 2000 French livers"
Yikes! Were those Frenchmen okay?
That was painful to hear
I'm not french but I know french and that scarred me.
Livers was a currency of france idiot
@@Aakshi-cy4hb No LIVRE was a currency of France, not LIVER, livre is pronounced the same way as the word for 'book' in French is pronounced, which is also livre.
@@Aakshi-cy4hb Look out everyone! A French expert who doesn't speak French has entered the chat!
Next we will learn how the main unit of currency in Mexico is the paysoap
Great look into the legend. Really eye opening. Haven't seen such high quality from a small channel like yours in a long time. I envision a bright future for you.
But
seriously fantastic video! Condensing an intresting piece of history into a bite sized tidbit is a real skill. Thanks!
lol "eye opening", "envisage", "bright"
Quite eye opening
What they both already pointed out 👆lol
@@Nobddy I hate the three of you XD bc I wanted to do this.
"I used to be a mathematician like you..."
So you could say...that's the day Euler lost his Eyedentity
Your channel is a goldmine!
Can't wait for you to hit 1M!
He saw the beauty of mathematics then there is no need to see other beauties for him. Great mind , great life. Very inspirational for us , inexperienced mathematicians.
Great video! The Swiss academy did not induct him as a member but Kathrine the Great started a National Academy and Euler was the first inductee!
[upon losing the use of his right eye]
Now I will have less distraction.
Don't lose sight of what's important.
I see what you did there
wow, ive always wondered how they made maps back in the day. excellent video !
This channel is a hidden gem.
I really loved that video, that I'm watching it again.
May you make a video series like this video?
This was dope af. Thanks for posting
Fun fact:
I started online school and every day since...my eye sight gets worst.
Like i cant even read a book on my lap or a laptop anymore + i have ghost vision on top of that which is seeing more than one of the same object. I cant read menus bcs i gave it all up for school.😀
Sounds like you've got what prisoners and submariners have, get outside more and focus on stuff far away and it should right itself in no time
Fascinating!
Thanks for the video.
Sounds like he got connected to some Borg equipment in order to solve all those map calculations in 3 days. It explains the eye trouble too.
This type of content easily deserves million subs
Extremely nice, informative video about a man who made life much better on this planet. Thanks.
Thank you too
Amazing video, directly subbed
I also created a theorem yesterday, Its formula for sum of square of first n numbes, The formula is I simplifed to 1 summation, so its: SUMMATION[i=0...n] (n-i)(2i+1) Thats it. Lets say 4. Summation[0...4], lets start with For i=0 (4-0) (For i=3) (4-1) + (4-1)+ (4-1) For i=2 (4-2)+(4-2)+(4-2)+(4-2)+(4-2) For i=3 (4-3)+(4-3)+(4-3)+(4-3)+(4-3)+(4-3)+(4-3) For i=4 (4-4) This become: 4 + 9 + 8 + 7 + 0 = 30 Now do it in normal way, you will get 30.
Amazing take on Euler’s biography !
Wait, this is Manim! Nicely done!

OMG i was just solving a math problem and I googled what e meant on the calculator. It showed showed the Euler's decimal and what I was looking for. And i come to CZcams to see this in my reccomended.
I always thought about that eye! I love Euler!
Great video !!! :)
I think Cauchy wrote even more papers than Euler. His lifetime of work was published in 27 volumes.
Euler 89
But Newton is still greatest for calculus due to which other mathematician became popular
Also
Euclid is the most greatest for making geometry or Elements (his book) , but Euclid is not so famous like Newton ,
In my opinion Ramanujan is great mathematician as he has just a simple education , and a book named Synopsis in pure mathematics (which book is contained 6000 theorem , and all of them are simple) but Ramanujan stiil makes impossible looking formulas in which most of them are still unpredictable and unproved and much work is lost
Euclid 🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥
I read once that it is customary to keep functions (e.g. "ln", "sin") and some other special characters (like the "d" in "dx") in maths in roman letters and pretty much only italicise variables. The readability of 1:26 for example would be improved if you adhered to that practice.
Loved this story
1:03 Isn't that Lagrange's four-square theorem? Please correct me if I'm wrong.
The greatest mathematician ever.

4:23 I surprised when I saw math article on my native language on this channel)
The only language wikipedia has this article in !
I heard he was part of a secret society. One eye, or hiding the hand, is a form to identify themselves.
But yes. he got blind...
Wait _why_ did he lose his eye? Did he have a genetic condition? Was the instrument he used to measure the stars leaded? Did the light from the stars burn his retina?
Oh, boy. Only if I can reach his level of mind, I am more than ready to give my one eye.
If he had followed in Tycho Brahe's footsteps, he would have lost the other eye in a duel :)
Such a great Mathematician
He loses i and we're still finding x
No I never wondered why his right eye was squinted because I never got past wondering what he is wearing on his head
May I ask what software you are using to make nice animations, like that at 1:09?
It is called Manim. You do it with Python.
Euler: I lost my eye to find the i.
sounds like he had some other conditions resulting in blindness, or a retinal detatchment
Eye for an i, as I believe the famous quote goes
Told ya! You are great...
u can lose eyes to cortisol stress, but I don't think its possible for that to happen just by working hard for 3 days. I think there was something else in Euler's life that was causing him a great amount of stress at the time, and he tried to use his work to take his mind off that stress. My guess would be he was madly in love with a young woman but the relationship didn't work, or didn't get started.
I suppose he was a chain smoker and also, he travelled extensively because of his cartography.
Euler has a mangekyo sharingan that does math.
My favorite mathematiation ❤
I thought he was going to put sticks in his eye socket to touch the outside of his eyeball and calculate based on the visualization of the pressure points... I'm weird.
*sighs
So is senior year math exam prep along with quarintine time screen staring deteriorating ma eyes.
He is a msster.
I can't still understand how he figured out that e^ipi = -1
He managed to prove that e^i(theta)= cos(theta)+iSin(theta)
If theta = pi, e^i(pi)= cos(pi) + iSin(pi)
= -1
3:46 the inclination of the earth's' rotation axis is known as 23degrees from elementary school
3:59 das ist mir neu. damals hatten die seefahrer noch kein gps, aber die Zeitzonen gab es schon immer und die Lage des Polarsterns über dem Horizont war aufschlussreich
the angle of the polarstar above the horizon tells something about the viewer's latitude.
if euler did not have a gift for calculating (think about the gauss, guldin's or kepler formulae) he would have had a problem.
I read his name in my fluid mechanics book
Stroke?
But why did he wear a newspaper on his head??
😄
Like Odin, Euler lost his eye to the Giant.
so what, so many kids lost their CHILDHOOD to mathematics, Euler is the lucky one XD
An accurate timepiece is necessary for accurate celestial navigation and cartography.
That's why any mathematician has Euler in the highest regard. Also telling stories about still having kids being an old man ha.
I love how you first give him all the respect he deserves then mock him.
Mathematicians that told me those stories considered that a feat (me too)
@@PiezasdeAjedrez yeah obviously it is, but, I feel that his personal 'achievements' should not be mentioned with his intelligence, wisdom and greatness in the field of his work.
good video
Norse mythology certainly has an impact to Germanic people
He lost an eye for mathematics, but literally.
legend
Or was it all his nights looking at Venus leading to a lifetime with Mercury?
Woah that was deep
But some stories says that his brother was the one who found out most of those calculations !!!
2:12 Euclid's proof a child can understand. This?
Thank God no need to rely on SponsorBlock!
I still don't understand the cause of his blindness. How does a mere fever have such an effect? There must have been other undocumented medical conditions.
Imagine working 72 hours straight, writing scribbles on a piece of paper. Euler was a workaholic and not everyone’ s body can cope with such stress. He turned completely blind eventually.
Stress and overworking can cause all sorts of issues in the body, and onna molecular level chemicals that are stable at one tempurature can become slightly less stable at another, and vise versa, so if your whole body is running just a little too hot, some chemical reaction that needs to run at a specific rate to repair or prevent damage can fail. I don't know the exact mechanism that caused him to go blind but it may be something like this
@@MetaMaths Might have a different cause still. Like an infection seems much more plausible.
@@IsomerSoma A healthy and well rested body can deal without problems regular infections, not so much if you overwork yourself for 72 hours!
@@txorimorea3869 that's right. happened to my left eye to some degree many years ago; like having a cataract blocking the pupil.
finally an answer
How does mapmaking cause you to go blind? That's impossible.
All those numbers did a number on his once 20/20 vision
He wrote 2 pages of maths papers per day... I would be content if I wrote one page in my life, of course a maths problem that's already been done many times
Euler is the top tier mathematician.
5:24 2000 French Livers 😧
Foreach i in eyes
{
Debug.Log(Look.i);
}
// Result: left eye is online.
// Result: null reference exception, i cannot be faund.
So wicked he finished in 3days what was he involved in ? Witchcraft or what
Imaginary alternative title: "Euler lost an i to mathematics"
Lol imaginary
That includes your profile pic
Omg 😯
How many of us would go blind for our career?
Depending on how happy it makes us of course!
Euler lost his eye but also found an i
The most name that I’ve encountered in science is Euler
This is misinformation. Euler didn't lose his eye to mathematics.
He lost his left eye to botched eye surgery in 1771, but the underlying cause of blindness in his right eye is unknown. However, there is no reason to believe that the intense astronomical calculations were the main causative factor in Euler's blindness (or even that they contributed significantly to the underlying pathophysiology). It's a mere coincidence.
It's understandable, however, that a layperson with no medical training would make the connection. Even more understandable when considering how poorly developed our understanding of disease was in the 18th century -- the germ theory didn't become widely accepted until the late 19th century. In the 18th century physicians believed infectious disease to be caused by miasma "bad air", and Nicholas Fuss wasn't even a physician. I wouldn't take Fuss's hypothesis (calculations -> blindness) too seriously.
The reason for Euler losing his eyesight in his right eye is unknown, but very probably unrelated to doing mathematics. It might've been an infection in a large blood vessel in his brain or a brain aneurysm, either of which could have caused damage to a certain nerve (oculomotor nerve) making his right eye's muscles lazy and eventually causing his brain to "abandon" the eye (through atrophy of the optic nerve) after years and years. The drooping eyelid is caused by damage to the oculomotor nerve (can't use certain muscles), but doesn't signify blindness -- the blindness came after the droopy eyelid. He lost his other eye when a surgeon tried to remove cataracts from Euler's eye (but the eye was bad even years before the surgery): academic.oup.com/cid/article/57/1/158/278749.
Thank you.
Real chad
Would you give your I's to see infinity? That's what Euler did.
Maybe he wa watching Sabine.
Odin is proud
He maybe lost an eye, but we lost too many brain cells
Now Euler won’t be able to find his x because he last an i
So "e" means "eye". Interesting 🙃
