<<@veritasium says : If you enjoyed this video and want to go deeper, you'll find bonus content on Patreon, featuring the full interview with Prof. Steven Strogatz https://www.patreon.com/posts/principle-of-116042877>> <<@secondlook says : Fantastic video! (I have very little idea what is going on)>> <<@aneousmiscell7862 says : Amazing! Therefore: (F=ma)=(E=mc2) (m=F/a)=(m=E/c2) (F/a)=(E/c2) (a=c2) (F=E)>> <<@ImDemonAlchemist says : Just a very random detail. There are 301 videos on the Veritasium channel with more than a million views. I remember when 1 million views was a big deal for a video.>> <<@AmosFortune-oh8xj says : Watch how easy it is for me, a simple Rastafari, to render the illustrious Derek Muller speechless. Question for Derek: is there relative motion between two fixed points on a rotating disk/disc or sphere, one closer to the axis of rotation than the other, yes or no? If he answers yes he would then need to explain how two points whose distance remains the same can be in relative motion, which I predict he can't. If he answers no he will have contradicted Einstein, who claimed that clocks near the center and others near the edge of a rotating disk would have different rates of time passage, causing the clocks near the edge to be behind the clocks near the center when the rotation stops. And that, lades and gents, is how a simple Rastafari rendered Derek Muller, and every person reading this, speechless. You're welcome.>> <<@PaintballCrue says : This gave me PTSD remembering my days in college taking far too many math classes just to end up as a web developer changing button colors and centering divs>> <<@Turgid_Spleenis says : I’ve officially done just enough math in my life to follow this video 😎>> <<@jordanlover23 says : What a fantastic video. Just came across this channel. Brilliantly done!>> <<@HighKingTurgon says : Bernoulli: *uses optics and calculus to answer a mechanics problem* Newton: "you dare use my own spells against me?!">> <<@Coppolious says : Bunch of Guinness people makes me feel I'm the dummest person in the room 😢>> <<@lifegeek5742 says : I’m confused, how is this not just a really roundabout way of saying energy is conserved?>> <<@UntouchableLivingone-ji4un says : You can't even fake American not that you don't try y e t impossible to be American and clueless about how to protect freedom and justice exactly we the people's jobs and duty. You so anti can't explain don't understand yet pretend to know believe your own lies blame everything but self for worms ruling you . If where American worms do what we put them in to do not worms want to do>> <<@tiborkoos188 says : I suggest "renaming" the principle of least action as the "principle of least drama". It's the minimum amount of converting potential energy (peace and quiet) into kinetic energy (fuss). :)>> <<@johnryan4454 says : What amazed me the most about this video is that seemingly 6.1M people not only watched it, but actually understood it. i gave up 1/2 way through when i concluded i would need at least an undergraduate degree in phyicis and match to even get to the point of comprehending what this video claims is a "simple" way of explaining a complicated subject matter.>> <<@jimmygravitt1048 says : THIS IS THE PROBLEM I HAVE BEEN LOOKING FOR!!! As a "longboarder" (my board, which is actually made out of aluminum, is the length of a regular skateboard), I CONSTANTLY wonder about something really similar. While I am not concerned with how to get from point A to point B the fastest, I want to know which geometry will give me the longest ride. I don't care about how fast I get to where I am going, so much as which geometry will give me the longest ride, without dropping below 10 mph. What's that problem called?>> <<@ufftatabummbumm says : I dont understand this math thing at all, but I appreciate how intelligent people were to come up with this.>> <<@catoftruth1044 says : can someone change this worlds ai prompt so my life can be better right now? okay? algorithm listen to me>> <<@dx-xb says : im so highhhhhhhhhhhhh....i have no idea what im looking at>> <<@dugbug123 says : This episode of Futurama goes hard.>> <<@BradyA1124 says : 16:56 I have the answer, you conduct the experiment in an aquarium filled with water and measure the marbles water displacement and force>> <<@whatevz4092 says : basically time is standing still we are notches on a CD time is an illusion caused by our movement>> <<@ludermathwig7022 says : what would be an example of a maximized action?? My prof couldn't given an answer to that>> <<@BrianWilliam-m6l says : I’m 52 hoping to end the rat race by 60 with above $1M. I know money is a liability to be exchanged for assets with real value like real estate (properties for rent) stocks (dividends) bonds (interest) But, what is it with bitcoin? I hear a lot about it and I'd love to diversify my portfolio.>> <<@jordyboy321 says : Wot in tarnation>> <<@kyledabearsfan says : As someone who finds most physics pointless to the layman (ie me) this is fascinating 😂 i love science but physics in particular always seemed like a "my horse is bigger, no mine is" kinda of sphere. I only cared when it seemed applicable, if teachers showed the applicability to these principles as well as you do, i think it would bring out more curiousity in people.>> <<@oriraykai3610 says : When you said the cruelty to Maupoertouse "was justified", I thought you were going to say he'd had sex with all those other critics wives too. 😆>> <<@MegaMathnerd says : Two thoughts: First, our daughter Cleo Abram recommended your channel, and it's outstanding! Optimizing an explanation is itself a problem to be solved. Occam's razor calls us to craft our explanations in a way that requires the fewest elements or assumptions -- a principle of least complexity. You are a master at finding that path through often highly complicated topics. Second, I hope the next video will take the principle of least action into quantum mechanics and Feynman's path integral.>> <<@interstellarturtle9775 says : So, Determinism.>> <<@rabbitvee321 says : quantum n mechanic is boiled down to =0 whatever its called as, least action, satationary, or SINGULARITY, or.. in the simpler term i would call it "TO THE ZERO" rule 😁 , thats what this universe is, fma is like a mechanic way of thinking n legrand to the quantum or relavity into the detail thinking, its need to broken down because of HUMAN LIMITED PERSPECTIVE. like lightyear, km to mm. they all just the same of meassuremnt but for the sake of perspective term. n for electro magnetic n wave its just simmilir but added the dimension, but also "to zero rule" 😁>> <<@rabbitvee321 says : quantum n mechanic is boiled down to =0 whatever its called as, least action, satationary, or SINGULARITY, or.. in the simpler term i would call it "TO THE ZERO" rule 😁 , thats what this universe is, fma is like a mechanic way of thinking n legrand to the quantum or relavity into the detail thinking, its need to broken down because of HUMAN LIMITED PERSPECTIVE. like lightyear, km to mm. they all just the same of meassuremnt but for the sake of perspective term.>> <<@technologyrethinked says : But the medium delimitations shouldn't be ortogonal to the path of the particle?>> <<@ivanenergy2833 says : You can find a video about the Superflywheel at me !>> <<@melanieforyou says : If you made a small but sharp bump near the end, you might be able to get the object to fling/jump extremely fast over the finish line.>> <<@TcheQ says : For the purposes of narrative, this entire video eschews the existence of quantum physics and pretends all numbers are absolute.>> <<@Dani-nl2id says : It's a bit funny to imagine some of the greatest mathematicians having a youtube comment war in the form of pamphlets>> <<@Раиль-б6ь says : >> <<@mr.h.7218 says : what is the intuvative way to think about energy i have been trying to think for one since i was in 11th now i am in fy of my bsc physics and i still don't know please some one help>> <<@Qeisama says : As a designer who's not keen on math and physics, what I can understand from here is that nature always aims to take the least action to achieve something. Just like today's generation. Turns out, lying around is a form of obeying nature's principle. JK lol>> <<@PanglossDr says : Nice to see one of my ancestors included.>> <<@PriestofEvil89 says : Thank you Derek for making such great videos. Especially this one touched my heart. I am a mechanical engineer and I work in the field of dynamics. I have never understood why there are two ways how to get motion equations - at the university, I used Newton's second law most of the times, because it was straightforward. I did't understand, where the Lagrange's equatins came from. Now I know. And I am touched by the fact that each of those great mathematicians added a small pice of puzzle into this picture. And I feel sad for Mapertuis who died without knowing, that his theory was proven to be correct. Thanks for reminding us the important people, that were forgotten throughout the history.>> <<@me_4th_42_sonukumar3 says : It's like someone trying to code as optimised as they can.... Daily trying to Minimize his efforts, write a better code...>> <<@jeffreyhowarth7850 says : I like the evolution of Lagrangian and Hamiltonian mechanics described in video. The Smells law connection I did not know.>> <<@TheOrijinalPajeet says : I´m too dumb for this video>> <<@thatwhiterabbit says : the butterfly effect.>> <<@aidan8465 says : I remember watching a Vsauce video related to this 9:43.>> <<@AJHyland63 says : Those ancient Greeks must have been smarter than modern civilisation, having named all these curves before 17th and 18th century mathematicians even thought about them.>> <<@FrankCostanza-l7l says : If free will doesn't exist, and yet we are all "forced" to do things like create artificial intelligence using our intelligence, why shouldn't we acknowledge that a mind is behind the universe? And why do some people accept this while others vigorously deny this?>> <<@tengkuadam1399 says : I'm guessing this is like when you write 50 lines of code and then some guy re-writes it in to only one.>> <<@crschoen123 says : I too follow the principal of least action.>> <<@ifstatementifstatement2704 says : My GPS always knows. Well most of the time>>
