Dope Tech Episode 2

<<@KUSHPRATAPSINGH-s9x says : Well, obviously, light takes all path, and the final one is the one we perciever. Kinda like that box cat😂>> <<@HKKvampiro says : It's almost like time doesnt exist ;)>> <<@l_z1478 says : interesting ......so light or photon been analyzing all and somehow we just see and ended up with the best result we seen>> <<@nathanwoodruff9422 says : It is the same way how a fart knows the shortest path to your nose.>> <<@ArthurMarston-i5h says : Jokes on you I already watched that video>> <<@park-ers says : Ohk, but how light chooses the optimal path?>> <<@TheXeneco says : 1:09 - are you sure about that? And what makes you so sure?>> <<@BV4551Pl says : Its quantum physics atp w/ light, taking every path possible to come across the shortest path?>> <<@Dm3qXY says : if i could report this video for misinformation i would...>> <<@frepi says : By the time it takes to decide what is the best path, your friend has drowned.>> <<@LUZinteractive says : Veritasium has become really crappy. Next.>> <<@Dm3qXY says : stop clickbaiting with idiotic titles.. the "explanation' is simple (if you can call it that.. considering it does not explain the BS the title is selling) : the word you're looking for is "WAVE" not "path".. the wave goes in all directions, including the shortest path's direction. but at least an animator got a job for it..>> <<@protocol6 says : I know what you are trying to communicate here but you've botched it so badly this is just misinformation.>> <<@mgr1282 says : Sometimes it is so optimal that light bounces back.>> <<@djancak says : yes, it's crazy because it's STUPIDER THAN HELL. LIGHT DOESN'T DO ANY OF THIS CRAP and it's so gross that you people keep acting like it does.>> <<@pavmal says : I had to do it in real life and instinctively followed that curved line, between running fast on the beach towards the ocean and then turning into water when swimming was a faster option. I would expect that majority of people will similarly triangulate the path in a split second.>> <<@tuapuikia says : You should run towards the path where the current flows. It reduces your energy to reach the victim. Don't ask how i know I am Gemini.>> <<@omj5149 says : Wait, light is organic?>> <<@ifstatementifstatement2704 says : Is there an algorithm to explore all possible paths all at once?>> <<@laslie-u6u says : Nope light doesn't take all the paths. Light during travel is not a particle but a probability wave 🌊. Light finds the shortest path because that's the closest moment and place it gets converted into a particle 😅.>> <<@NatePrawdzik says : This sounds theoretical, but this happened to me, except I was swimming towards shore to help. I didn't take the optimal path and got there too late to prevent a tragedy.>> <<@evancasper says : I disagree>> <<@luqcrusher says : I… what. What was this short. It didn’t give a proper explanation>> <<@dhavalmysore says : Your original video, posted about a year ago, has several comments, and follow up videos by other youtubers, showing the misunderstanding of "literally takes all possible paths" and they even called out Casper's flawed experiment and interpretation. Are you going to do a follow up to address and fix your misunderstanding or keep posting this short to promote your misunderstanding of the concept of all possible paths?>> <<@goldthereal says : Hear me out on this. If you saw an infant tied to a passenger jet, dragging it behind itself, you would think there must be an external force making the plane move, such as a pilot, because it isn't physically possible for an infant do do something like thatĺll. Now let's apply the same logic to this: Light does not have life, power, knowledge, or free will, so there is absolutely no possible way light chooses the optimal path itself. Therefore, an external force that makes it behave that way, must exist. You might think that force is nature, or the laws of physics, but that cannot be the case. Nature also doesn't have life, power, knowledge, or free will. It also cannot be physics, because laws cannot accomplish anything by themselves, and here's why: Imagine there's a piece of paper with a rule; Only the letter A can be written. Can this rule write the letter A? It can't. A person with life, power, knowledge, and free will has to use power and free will to consciously pick up a pencil, and choose to write on the paper. It is not the rule that makes the letters get written. It is the living person with free will, making a conscious decision, using power to execute it, and knowledge to do it well. Since physics can't be behind light's behavior, it must be something else: God has life, free will, power, and knowledge, to make light behave that way; Like how a pilot with knowledge of how the airplane works, and makes a conscious decision to move the airplane. And that is why I believe in God. Hope this makes someone question things.>> <<@JDogtheAutisticGiant says : Sponsored by the life jacket industry?>> <<@jtu0929 says : John 3:16 “For God so loved the world that he gave his one and only Son, that whoever believes in him shall not perish but have eternal life” Jesus loves you>> <<@baldybaldmann says : Me after using hoverboard to save my friends 🗿🗿🗿>> <<@AlvinYakitori-ib3bi says : "Craziest fought experiments" and your explanation needs a lot of work. Light doesnt travel to point B, where even would that be? It doesnt have a destination, so of course if you pick a point on its trajectory it will be "the shortest distance".>> <<@zataralee2 says : Quantum theory... ?>> <<@VeNoM0619 says : Light is simply being interfered with in the denser medium, slowing it down and changing the direction slightly.>> <<@ruudh.g.vantol4306 says : Follow your nose!>> <<@iswissmiss says : Makes more intuitive sense that light's wave function coalesces at a peak that aligns with the path of least action.>> <<@arnavramesh3784 says : Re-upload??>> <<@andome2 says : The exact solution can be found using calculus, if you are not certain whether Fermat law applies or not. You just take the derivative of the merged path equation and see the minimum function value, hence the fastest way.>> <<@matthewmathis62 says : God is light.>> <<@myoptic-h6f says : I love that someone decided to get fewer views by going with a shirtless dude in the thumbnail instead of the more obvious click magnet>> <<@junkerzn7312 says : Basically what happens is that light takes all paths, but the wavefronts to the left and to the right of the "optimal" path wind up interfering with and canceling each other out so you wind up only seeing the optimal path. However, all those other paths are very real, the light is actually going through them, and one can block off or create gaps on the medium/mirrror/lens/etc, changing how the interference cancels out, to demonstrate that. This is also why a larger primary mirror or lens is needed to resolve finer features in objects. The image is being constructed through mass interference from the incident light and you lose information when you have a smaller primary mirror or lens. It isn't just about light gathering (brightness)... actual information needed to resolve the object is lost, resulting in a fuzzy object. Lithography processes and long-range telescopes and cameras have to deal with this issue big-time. -Matt>> <<@ShabeerSniper says : I'm sorry there is no final path, light moves in all directions at the same time, it doesn't go everywhere then the waves decide "ohh right! this is the best direction" and they come together for a singular wave. Thats just stupid, I know this guy isn't stupid hes just misrepresenting it for views>> <<@yagneshraviteja says : Who is this new face, Dareks son ?>> <<@Navoii. says : It guesses every time and we live in the universe where it’s always right>> <<@rageshravichandran7489 says : Whaaaat.!?🤧>> <<@Wrestlingfan1245 says : So basically how quickly you rescue them depends how fast you can run and swim. Who’d have thought 🤯>> <<@werta175 says : why gay>> <<@eSKAone- says : The faster you go the slower time goes. When going at light speed time slows to zero. So there is only 1 photon in the universe and it is everywhere it shows up at once. In some places it shows up multiple "times".>> <<@martinstent5339 says : You didn't mention the Feynman explanation about the phase of all the "virtual" waves.>> <<@Ana_crusis says : This makes no sense at all. Obviously you're going to have to run down the beach and into the water and then it would depend on if he was being pushed along on a Riptide or not. you might need to head directly for him, or where you think he's going to be in the time it takes you to arrive there. But your formulation of just running instead of swimming is nonsensical. I presume you've got a clear idea in your head but I don't think you've explained it very well.>> <<@Dyslexic-Artist-Theory-on-Time says : Light takes every path as a spherical wave, based on Huygens's Principle of spherical 4πr² waves. This can be explained with light as a wave with particle characteristics when we have the absorption and emission of light waves. With a photon ∆E = hf electron interaction between each cause and effect, between each action and reaction with the Planck constant h/2π being a constant of action. This process would form an interactive probabilistic uncertain future in space ∆×∆pᵪ≥h/4π and time ∆E ∆t ≥ h/2π. Photon energy is continuously exchanging potential energy PE into kinetic Eₖ=½mv² energy forming greater degrees of freedom for entropy.>> <<@king_noah1210 says : What does “all possible paths” mean here? This explanation is not very compelling.>> <<@mtk77621 says : still not explained>>
