The Most Complex Language in the World 

Go ‘beyond the nutshell’ at brilliant.org/nutshell/ and dive deeper into these topics and more with a free 30-day trial! This video was sponsored by Brilliant. Thanks a lot for the support!

I’m in a college biochemistry class and we had to memorize the structures for the amino acids, I loved how the little animated pictures for each amino acid actually resembled the real structure for each, fantastic job on the artwork for this one!!

As a biologist I can only say that this video is a masterpiece! The animation work is done beautifully to show how complex "the language of life" really is.

This channel overall deserves an award for science communication. The complex topics that get broken down in a way so that nearly anyone can understand the basics of said topic is an amazing feat.

I'm a simple-minded translator and teacher. I have never seen a message conveyed more succintly and a topic explained more thoroughly yet plainly than this. Now I have a vivid image of how my cells communicates. Great work, guys! Thank you.

I'm a molecular biologist and this video explains complex mechanisms in an amazingly simple manner! The artstyle is visually stunning and narration is brief and simple.

looks like the art and animations reached yet another greater level, i cannot even understand just how much effort you guys put into this

Space and molecular biology, two of the most fascinating topics one can immerse himself into. Keep up the amazing work.

As a Med Student that has seen/studied most of this stuff, I find myself so happy and in awe at seeing this. Sometimes it's amazing to take a step back and see everything you know to prepare to the future. Thanks for the inspiration, Kurzgesagt!

You guys won't believe how valuable these videos are for us. Just remember we are so really grateful for you guys.

As a Microbiologist, this video is amazingly simplified with the essence untouched and with a clear understanding of how it works. Considering how extremly complex is this, it's an incredible work!

"....but if you look inside of what you really are, you just discover almost indescribable complexity, a beautiful language of life" This made me rethink things from a different perspective, thank you

Just finished third year of my analytical biochemistry undergrad degree. It has taken about that many years to understand these concepts to a sufficient level for my field. It always makes me a bit sad that this beautiful and important process will not get seen by most people. Obviously this is a simplified version but I really hope people appreciate this video and that it is a look into a mystery still being uncovered

This video allowed me to confirm the accuracy of this channel's content. I've studied molecular oncology for 13 years and have a PhD in Human Biology and Genetics and can say that this channel is the way to communicate science to everyone. Biology is unbelievably complex, and more I deepen knowledge into specific molecular mechanisms, and more I discover how much we don't know about it. This makes me appreciating the depths of other fields, incentivizing learning over creating superficial opinions. The superficiality by which COVID vaccines have been misjudged by the people not in the field, reminded me the importance of education and to teach critical thinking in schools.

If I was a high-school science teacher, I'd consider making my class preparation loading up Kurzgesagt videos and pressing play whenever possible. For years this channel has been expanding the art of making science thought-provoking, memorable and easily understood.

The animation is god tier but the music and sound effects are criminally underrated. Massive appreciation to all the team effort.

Am I the only person that cried a little bit because of how beautifully life was explained in this video?

As a normal person who breathes for living and not a biologist/doctor, this video is really very informative. Also i loved the animation.

This is the video that I've been waiting for so long. People just don't talk about Cell Biology enough when in fact, this is arguably the most diverse and fascinating field of biology. It underlies almost every thing in biology, from immunology to developmental biology to neuroscience. As a cell biologist, I feel incredibly proud to be part of this beautiful field.

watching this as a biomedical sciences student adds a layer to it really.Awesome work to simplify something so incredibly complex that we still don't know all about it.

I really needed this. Was feeling down and suicidal about personal issues, then stumble upon Film theory coma video and that sad story makes me appreciate life on a emotional sense, and this video helps me appreciate life on a technical and complex sense. Never thought about how billions of tiny robots are working endlessly to keep me alive. Can't let them down like that.

I am not exaggerating when I say this, I promise you. Kurzgesagt has changed how I view learning as a whole. When I was younger I couldn't care less about nature, space, biology, and anything that required learning. This was partially because of my ADHD. I found this youtube channel about a year or two ago and it has changed that entirely. Kurzgesagt sparked a certain curiosity towards the world I never really knew before. This may also be because I simply got older, but Kurzgesagt helped. I live life, space and the mystery of all of that as a whole. I mainly want to go to college for art stuff, but I am tempted to also dive into any kind of science. As stupid and overly ambitious as this sounds it's true. Kurzgesagt is an underrated, inspirational work of art.

I love how they are honest and confident enough to admit when they don't know a step or two. That attitude is incredibly important in science. Great video!

So grateful for the work you do, communicating and educating on such complex issues in an accessible way. When a video starts and I get the feeling that it's going to be a good one, I bounce excitedly in anticipation, and rock happily as I go through it, back and forth until I'm sure I got it. Nothing like understanding our existence a little better to make life more bearable and even more exciting. And this adds a joyous mindfck to the existential crisis playlist. You guys are my favorite channel. Thank you so much

Fantastic job in breaking down such complex concepts and principles of Chem and Biochem to the laymen. Finished Chemistry in Uni but currently working in business and this made me miss the magic of Science so much. Honestly it made me teary on the last bit while having goosebumps. Fantastic work as always guys!

"If you look outside at the incredible dimension and scale of space, a place where forever is a real thing, it is almost impossible not to feel a bit small. Not special. But if you look inside, into what you really are, you just discover almost indescribable complexity, the beautiful language of life." This quote is pure genius - it captures the contrast between feeling small in the universe, yet containing a world of complexity within ourselves. It's almost like it brings balance to these two perspectives that I've felt at different times. It's a perspective I've never heard before, and it feels almost groundbreaking. Whoever wrote this quote has captured something truly special.

I am a cellular and developmental biologist, taking masters developmental genetics and performing research on regenerative medicine. It took years of intense math, chemistry, physics, and genetics before we began discussing protein folding in 3d space, overall behavior in four dimensions, and how we can start to model them bioinformatically (6:23); however, the subject is introduced in 12 minutes flawlessly, and could be shown to middle school students. Well done!

“How dumb things are smart together” blew my mind, and the analogy with the ant and cells was perfect for someone like myself with a non-science background to understand. It would be great if you could cover complexity theory

Really great job making a concept thats too complex into something everyone can understand! I even love how transperant you guys are, showing the part thats "advertising". Great job guys, keep going! We appreciate all your efforts.

This channel has hands down some of the best explanations of science for all ages. Thank you to everyone who works on these videos. Planning, drawing, developing, recording, everyone. Thank you all

This animation is like music for my eyes. Kudos to the animators for creating these masterpieces

Kurzgesagt: "Although dumb individually, they become something greater together" 8:42 Also Kurzgesagt immediately after: Shows moving image of human traffic

"But if you look inside yourself you just discover indescribable complexity". We needed to hear this.

Biology teachers are going to be using this video for years and years to come, I'm certain of it. I have a bachelor's in biology and now I'm in med school - but you just explained what took me years to understand in less than 12 minutes. I'm blown away by how much love and thought went into this. Incredible as always

This is a wonderful coincidence. I just finished my semester finals on Human Genetics yesterday which had all the topics covered in this video from what amino acids are to how they are made from DNA and how they are responsoble for most of us. I enjoyed studying this with my friend because it is just beautiful. Kurzgesagt drops a video covering the same topic and illustrates it in a much more beautiful way than my prof. Definitely sharing this one. I loved this one especially because it means something to me.

as a geneticist, I'm never able to convey the sheer complexity of this field to anyone as well as this video managed to in 10 minutes

I have been watching for years, and this is definately one of the best videos yet! We need more videos around this area! Breaking down how to human body works in such a small scale is just mind-blowing. Thank you!

I rarely comment on anything on RU-vid, but I felt motivated to do so here. I used to be a Biology and Earth Science teacher and now I lead a small team of educators for a conservation organisation. I am the only one with secondary and tertiary teaching experience, so I'm currently running staff PDs to upskill my department. So far I've taken everyone through the very basics of organic chemistry, all the way up to rRNA and the beginning of cell structure. This video is beautiful, brilliantly written and so incredibly timely for me. I have used some of the very same metaphors myself. Two of my core staff are going on leave the day after tomorrow and we won't be able to do any PD for two weeks. I am showing them this tomorrow afternoon before they go on holiday. Thank you for making science awe-inspiring for millions of people.

I'm a biologist and I was entranced and amazed at how you guys made this insanely dense topic accessible to everyone! Amazing animation and video! Great work!!

How elegant and simple this analogy is for such a complex topic. Not only I find Kurzgesagt videos amazingly educative but also deeply moving. More than teach your audience, I believe you inspire it.

Why I always cry at the end of these videos? So majestic, well edited, and animated. Beautiful.

As a biochemist I'm showing this video to my whole family so that they might understand a bit more what it is that I'm actually doing/researching! 😍😁

Never seen biology explained this way. Being able to explain something clearly using metaphors shows great understanding of the underlying concept and fundamental idea rather than just the subject specific knowledge. I love this video and there is too much to be said for the awesome animations. Well done Kurzgesagt team!

7:16 _Monke strong together_

This is in my view one of the best video's I watched from you all. Incredibly tough topic bordering on the philosophical "what is life" question described in an extremely accessible manner with enough detail and well made animations showing amino acids and such binding together and executing pathways.

Even though as a person who's currently in medschool and has thoroughly studied all these concepts, these videos truly make you look into our human biology in a different way than the usual. Astonishing video as always, love you guys!

As a biologist/biochemist this video is such a beautiful reminder of why biochemistry and microbiology captured my imagination - I have never seen the language of life explained so elegantly, clearly, accurately and beautifully as this video… it has to be the best video you’ve produced yet (and that is something given how high a bar your videos set!)

Does anybody see the audio and video desinchronized in this video? It also seems like the first part of the video was cut 😢 so sad. This is the best explaination of how life works ever

These video are so useful for understanding broader topics we could never hope to understand otherwise! These beautiful videos mean so much, thank you!

My kids are still young and not really good in English so I made a translation to Ukrainian for them and read it simultaneously with this video. Kids enjoyed it so I decided to share it here. It broke down to the same sequences as original English subtitles in the video. 1/2 Ви - клітини. Ваші м'язи, органи, шкіра та волосся. Вони в вашій крові та кістках. Клітини - це біологічні роботи. В них немає ані бажань, ані відчуттів. Вони ніколи не сумують, та й не розважаються. Вони просто є, саме тут, саме зараз. Вони так само притомні, як то каміння, стілець, або нейтрона зірка. Клітини всього лише виконують програму, яка еволюціонувала і змінювалась протягом мільярдів років, обумовлена природнім відбором. Вони неможливі машини, але ж ось вони, рухомі лишень самими фундаментальними силами всесвіту. Найменші одиниці життя, як раз на межі де фізика стає біологією. Іноді, для того, щоб по-справжньому осягнути те, на скільки дивовижним будь-що насправді є, вам необхідно затримати дихання і зануритись дуже глибоко. То що ж насправді таке ці клітини та й як вони працюють? КОРОТШЕ КАЖУЧИ Гляньте на кімнату в якій ви зараз знаходитесь. Давайте заповнимо її до самого верху трильйонами піщинок, мільярдами рисових зерняток, сотнями тисяч виноградинок, кількома тисячами яблук та дюжиною кавунів. Саме так виглядають з середини ваші клітини. Кількісно, вони майже цілковито складаються з молекул води - те, що пісок. Вода створює в клітині желеподібне середовище, що забезпечує можливість іншим частинкам вільно рухатись всередині. Майже всі інші частинки, як то рис і фрукти - це білки. Загально, декілька мільярдів, (Більшість речей показаних у цьому відео набагато складніші в реальному житті. Ми ілюструємо їх символічно, для ясності візуального оповідання.) більше 10,000 різновидів, в залежності від функції клітини. Ваші клітини в сутності - білкові роботи, так само і життя, як таке. Насправді, всі щільні, не жирові частини вашого тіла, майже цілковито збудовані з білків - навіть ваші кістки. Білки - це мертві частинки, які змушують життя відбуватися. Як же ж це працює? МОВА ЖИТТЯ Клітинам необхідно робити багато складних речей, щоб залишатися живими: Поглинати їжу та скидати відходи, зростати і будувати структури, уникати небезпеки або реагувати на стимули, робити копії самих себе і так далі. Все це відбувається завдяки використанню мови життя. Словами цієї мови є саме білки. Ось стисле пояснення того, як ця мова працює: Все це починається з імінокислот, дрібнесеньких органічних молекул. Вони є алфавітом мови життя. Існує 21 різна амінокислота, як різні букви. Амінокислота А, амінокислота Б, В і так далі. Якщо зберете разом 50 амінокислот, вони сформують білок, який в мові життя уособлює слово. А якщо ви зберете разом багато таких білкових слів, то вийде речення, яке зветься біологічний шлях. Давайте максимально спростимо і скажімо, наприклад, вашій клітині необхідно розчинити цукор за допомогою мови життя. Вона візьме амінокислоти відповідні до літер р, о, з, ч, и, н, и, т, та и, щоб сформувати білкове слово "розчинити". Далі, складе це слово з іншими білковими словами, щоб сформувати біологічний шлях "речення", яке означає "розчинити цукор". Насправді, ця мова життя настільки складна, що не піддається уяві. Вам необхідно знати приблизно 8000 слів для того щоб вправно розмовляти людською мовою. Але мова життя нараховує щонайменше 20,000. І в той момент, як українське слово має в середньому 7 літер, людські білки складаються в середньому з 375 амінокислот. А найдовший білок має більш ніж 30,000! Крім того, клітинам необхідно виконувати тисячі дій в кожний окремий момент! Якщо вони колись припиняють розмовляти мовою життя, то помирають. Добре. Але ж, як бездумні клітини розмовляють настільки складною мовою? Давайте зануримось ще трішки глибше. Існує 21 амінокислота, які можна складати, утворюючи білки. Та білки створені з десятків та сотень, та тисяч амінокислот. Для людського білка середньої довжини в 375 амінокислот, ви отримаєте приголомшливі 6.8 * 10⁴⁹⁵ ступені можливих варіантів, які здатна створити ваша клітина. В квадрильйон гугол, гугол, гугол, гугол разів більше ніж атомів у всесвіті. Більшість з цих можливих варіантів білків негодящі. Так само, як і в людській мові, переважна більшість випадкових комбінацій літер є звичайна тарабарщина. Таким чином вам необхідно знати які слова, які білки, є мовою, щоб розмовляти нею правильно. А це вже робота вашої ДНК - довгої послідовності інструкцій. Якщо розплутати ДНК окремої клітини, її довжина складе приблизно 2м. Всі ДНК вашого тіла, з'єднані в єдину довгу стрічку, дісталися б до Сонця і повернулися на Землю більш ніж 20 разів! Приблизно 1% вашої ДНК складається з генів, які в сутності білкові словники, що містять всі слова мови життя, якою розмовляють ваші клітини. Але в той самий час гени є інструкціями з будування для всіх білків, що необхідні вашій клітині для функціонування. Решта вашої ДНК скоріш за все не є непридатною, а у своїй основі, типу набір правил. Щось на кшталт книги з граматики мови життя: Які білки треба створити та в який момент? Як багато їх вам знадобиться? Які саме білкові слова використовуються разом, та чому? Добре. Літери, слова, речення, словник та граматика. Але ж звісно все це лише метафори для чогось приголомшливо складного. Давайте зануримось ще трішки глибше, щоб хоч злегка осягнути реальність.

As a geneticist in the pharmaceutical industry with a background in microbiology, I can't help but say The animation work is done beautifully to show how complex "the language of life" really is. Much more engaging than our teacher back at university :P Keep up the good work!

This is probably my favorite video about biology from this channel. The part about how protiens fold and connect based on the electromagnetic charge was mind blowing. Its like where physics meets biology! So incredible.

I had a period when I was interested in biochemistry and got all A's in biology but nothing I'd learned at that time made me awe as much as this video's explanation!

I wish all my lectures throughout college could’ve been this beautiful. It’s so useful to see these concepts animated like this!

It's crazy how such complex tasks make simple things happen, and it is barely noticeable because of how quick it happens Edit: Actually should be complex tasks coming from simple things occurring instead of "complex tasks make simple things happen".

I'm studying Bioinformatics at college and this video helped me soo much. Biochemistry is really complex for me since i had little to no chemistry classes in my engineering high school and these animations made everything so much clearer, thanks❤️

"If you look outside the incredable dimensions and scale of space, a place where forever is a real thing, its almost impossible not to feel an bit small, but if you look inside into what you really are, you discover almost indescribable complexity. The beautiful Language of Life." This can be summarised into 1 word : Equilibrium

People need to understand that it takes a lot of time to get this understanding of biology and "language of life" even while studying biology, biochemistry, medicine etc. As a med student I think this video should be in the curiculum for the first years (premed first year). Even though I knew all about that, seeing it with this animation and explanation made me understand better. I thought it was because of my lack of knowledge but seeing all the great biologist and biochemist also commenting on that really shows how great this video is. Thank you Kurzgesagt!

As a computer science major, this video truly made it seem like our billions or trillions transistors still couldn’t replicate this language of life.

It's a freaking miracle that most people's cells, their bodies, just work. It would be like if you threw a million Legos onto the floor, it assembled itself and got a job without your input.

Not only it was very educational, but made me emotional as well. Thank you so much for this amazing work

As a biologist, this was wonderful to watch. Much more engaging than our teacher back at university :P Keep up the good work!

God, not only was the video astonishing, it was a true nostalgia trip. I loved how the metaphor was implemented, as well as the visual media used. It looked as if I was watching a program made for kids, while not be talked down like one. Great Job!

"What's your first language?" *the language of life* "What-" **protein noises**

This video is incredible. Thank you for all your hard work to communicate these concepts in a way that's meaningful, easy to grasp, and mind blowing all at the same time. I want to show this video to all the people who struggle to understand how unanimated molecules could lead to whole, conscious, living beings; in other words, how a dog could have evolved from a rock (their words) over billions of years.

"If you look outside the incredible dimension and scale of space, a place where forever is a real thing - it is almost impossible not to feel a bit small, not special. But if you look inside into what you really are, you just discover almost indescribable complexity, The beautiful language of life" Blissful true words✨✨

Im 32 and just started college after not being in school in 11 years. I've gone back to be an RN and just finished my first exam in anatomy and physiology. Chapter 2 and 3 were about microbiology and some chemistry (which I can't get enough of). I'm highly considering a life long career in microbiology or biochemistry. I can sit around trees watching birds pass by myself while in complete awe as i see the world like i've never seen before. This video is really speaking to me right now. As always, great video!

I have seen almost every video of yours, and this one might be my favourite. You are doing the best work on the internet, no joke.

A truly stunning video, I loved the visuals on this one!! Great work, thanks for creating this interesting videos!

The animation is so smooth. I’ve watched this channel for years and the progress with each video always put me in awe.

Damn, all the space videos made me feel like nothing when compared to everything out there, and somehow but unsurprisingly this video made me feel as big as the entire universe. I love how you guys always manage to make stuff I normally overlook actually interesting to learn. I’m glad I found this channel all that while back when I did, for all of this content is completely worth it.

Wow this was very helpful I was just learning about transcription and translation. This video helped me understand how that process makes the proteins

This channel brings me from the biggest things observable by mankind, to the smallest things observable by mankind. Makes me feels really insignificant but also mind numbingly unique. Really great contents to inspire society in the time when information is dominated with just gibberish and numbing mind kind of information.

It astounds me how you guys always manage to explain mind-breakingly complex things in a simple way with fun and useful graphics, such that even a kid can thoroughly enjoy it - all without it ever feeling unnatural or like you're talking down. Videos like these make me wish we prioritized education so, so much more than we currently do. I can't even imagine what the world would look like if we taught our kids using engaging and fun materials that are easy to understand like these videos are. Instead of boring them to tears and stiflng any desire to explore interesting topics, it'd be amazing if the resources were there to really engage with each kid - to let them explore their individual passions instead of cramming pre-packaged lesson plans down their throats.

6:21 HE DID IT, HE SAID THE THING!

Finally I get it... how this world works. Just amaizing vid - graphics and description of it is very simple (which means is very good). Great work! Дякую!

Wow. I’ve never seen such a wonderfully clear and understandable demonstration of protein theory. Well done!

As a sentient bunch of cells, I can say I cried, thank you💚

The visuals in this videos are stunning, I always love how creative they get while representing the smallest things

I LOVE the oversimplification! It really does make these types of things so much easier to understand, grasp, and imagine. Most of this shit is MINDBLOWING! 💨

I would love a poster or some kind of merchandise with some of the visuals in this video! The animations are gorgeous, I'd love a poster of the amino acids and proteins

Literally one of the finest works in the history of science communication.

As a doctor, we have Biochemistry as a subject which includes all that is mentioned in the video. Believe me, this is the best version of someone explaining so complex and difficult in a comprehensive and palatable way! If only we had videos like this studying them would have been fun. I regularly watch Kurzgesagt videos, they are precise and factually correct. The way they make animations so good everything seems connected to the voiceover explaining. I would love that someday my kids would learn from this gem of a channel!

This channel isn’t anything less than the very best way to communicate to children and adults alike in a way that is incredibly interesting and reliable. These people deserve an award for making such beautiful videos.

Unbelievably beautiful way of explanation!

Every new video sets a higher benchmark for vector based animation. I'm at least five years into After Effects and with every kurzgesagt upload my soul gets crushed by how far you guys are ahead. But I can appreciate the beauty, find things to learn for animation and - of course - science! So thank you!

I hope you realize that by providing this education it makes people in general more likely to pursue a career path in these fields because the topics are so interesting. Any advancements in the future will therefore have been directly or indirectly caused by you :) whether someone learned from you or interacted with someone that learned from you. Thank you for your work :) Please keep it up 💪

I would say kurzgesagt, you've done a great job. You just explained the most complex thing sooo easily. All the teachers around the world couldn't do it. You just did it in 10 mins. ❤

This video blew my mind, thank you so much for the awesome content!

I have a degree in molecular biology... this video got me goosebumps all over! Thank you for what you do!

This is literally the climax of everything I am learning in physics, chemistry and biology, so cool

Interesting take on proteins and amino acids, I always saw them as building blocks to form complex mechanisms that do specific things and that view is still intuitive to me but now I'm thinking about sounds/letters and words differently, like they are building blocks of a complex mechanism which is forming an idea or picture in the brain of the person reading or listening to those words

This video's simple in depth explanation of a bonkers topic so effortlessly is really stunning me right now. Hell, biology, organic biology to boot, makes so much more sense to me now!!!

Interesting use of language as an analogy for protein pathways. Never would've thought of that myself and might steal that in future lessons with students on biology. As always, Kurzgesagt never fails to deliver digestible summaries of incredibly complex topics.

I’m in biology this year learning about this stuff! I’m definitely sharing this video with my teacher

Are you going to make a second immune book? I finished the first one and I loved it.

This video reminded me of my first college class about what DNA Polymerase really is and how it actually works in 3d space. It was the most amazing thing I had ever seen.

Kurzgesagt, I want to express my deepest gratitude for the incredible work your team is doing. Words can hardly do justice to the beauty and impact of your videos. Every person in your team, from the animators to the sound engineers, scriptwriters, editors, narrators, and all the other contributors I am failing to name (my sincere apologies), is doing an outstanding job in creating a magnificent demonstration of what humans are capable of achieving. As a viewer, I'm constantly amazed by the level of detail, accuracy, and creativity in your videos. I'm sure I speak for many others when I say that your work has touched and inspired us in profound ways. Your dedication to making complex topics accessible and engaging is truly remarkable, and it's evident that each member of your team brings a unique and invaluable skill set to the table. Thank you for all that you do, and I always look forward to seeing even more of your amazing mind-expanding creations in the future!

What a wonderful metaphor! As a future language teacher and former biotechnology student, your video is both touching and exhilarating!

Animations are soo good The cells are really well designed and detailed
