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.

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.

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

I’ve officially done just enough math in my life to follow this video 😎

What a fantastic video. Just came across this channel. Brilliantly done!

Bernoulli: *uses optics and calculus to answer a mechanics problem* Newton: "you dare use my own spells against me?!"

I’m confused, how is this not just a really roundabout way of saying energy is conserved?

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). :)

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.

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.

16:56 I have the answer, you conduct the experiment in an aquarium filled with water and measure the marbles water displacement and force

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.

@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.

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.

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" 😁

But the medium delimitations shouldn't be ortogonal to the path of the particle?

You can find a video about the Superflywheel at me !

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

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.

It's like someone trying to code as optimised as they can.... Daily trying to Minimize his efforts, write a better code...

I like the evolution of Lagrangian and Hamiltonian mechanics described in video. The Smells law connection I did not know.

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.
