<<@veritasium says : We have a tabletop game launching! Pledge your support now - https://ve42.co/KickStarterD>> <<@Anhh2k7 says : nếu vậy nhiệt độ trái đất tăng thì không phải do lỗi con người chỉ vì mặt trời truyền cho trái đất nhiều entropy hơn thì nhiệt độ con người tạo ra nhiệt độ cx cao hơn thì trái đất cx toả ra nhiệt đo cao hơn ra vũ trụ thì sao nhiệt độ trái đất tăng ?>> <<@qjim16 says : Notas: 1 Leis da termodinâmica > Primeira lei: energia de um sistema fechado é constante; Segunda lei: entropia tende ao máximo (sistema fechado: entropia aumenta ou fica constante, mas jamais diminui). 2 Entropia baixa do sol: energia acumulada, compactada, concentrada... depois espalha e espalha. Terra > energia que entra = energia que sai. Contudo, 1 foton energético recebido (f alta; 480 nm) = 20 fotons saindo (10.000 nm). 3 A vida pode ser decorrência da segunda lei. A vida é uma estrutura excelente para gastar e espalhar energia (acelera chegar à máxima entropia). Seja uma sopa de átomos (sistema), recebendo luz (sol), com o tempo não se assuste se uma planta aparecer. 4 Curiosamente, a entropia de buracos negros é GIGANTE, mas ao mesmo tempo são super FRIOS (quase 0 K).>> <<@richardmcbroom102 says : On the Internet I have defined prime numbers as "resonators" that divide into certain numbers without fractional remainder. In that sense the counting number 1 is a "trivial" prime number, as it is a resonator with every counting number. Identifying the fine- structure constant, alpha, as universal 1 (by definition) in my top-down cosmology means alpha, alpha squared and alpha cubed have "profound" (as the AI stated) cosmological significance, as alpha is a apparent resonator with pi in high energy physics, and by definition has zero rate of change.>> <<@aiasachaion says : it all started with the big bang but who wound it up? and who wound that thing up? i am perplexed>> <<@Ternoawleift2 says : i dropped out of high school due to severe anxiety, and i’m so appreciative of your videos for allowing me to continue to learn about science, as i’m absolutely fascinated by it. i hope to someday go back to school, and because of you i know no matter what we’re all still capable of>> <<@t.bayviking3232 says : Entropy is used in our bodies by God. Everything is in entropy and falling apart. Mountains, wood and everything in the world is decaying and falling apart. Second Law of Thermodynamics.>> <<@johnwight6041 says : Man I love physics. So excited to finally be able to study it as a major in university along with computer science!>> <<@SushilaBagul-q4y says : I wanted to study entropy and thermodynamics since a long time..this video helped me a lot. Thanks veritasium!>> <<@saxz99 says : ayy the appeal to authority min 17:20 was painful>> <<@memirandawong says : I recall an example of entropy (I think) when I randomly sat next to *you by chance on a flight from London to San Francisco; Side by side (hi entropy) in perfect stability for a few hours. But, who knows where you are now! (low entropy) It was a long time ago (decades) and when I asked what you did for a living you simply replied: "I'm a physicist". I didn't realize it was you until I started watching your videos. (* of course there's a chance that was NOT you but I think my memory serves me well here."😆>> <<@h4tchetman says : 13:46 so your're saying.. there's a chance!>> <<@visualconceptlabstudio says : One of the opportunities that AI has given us in education is that we can now better learn abstract and complex concepts like entropy.>> <<@Chonk-on2wm says : coming to watch for a better understanding of entropy in my ENG thermofluids unit left with an existential crisis>> <<@Fvpigpen26 says : Earth gets heat, light,and energy, We get time and vitamin D along with food medicine and poison. 0:40>> <<@mjcatalyst2391 says : Good old days 💎>> <<@SerenityOne-i9k says : 0:40 bombarded by (ok stuff)>> <<@SerenityOne-i9k says : 0:10 in he beginig was he big bang. Aka mass entropy. 😅>> <<@bwhog says : The problem with the explanation at the end of the Ideal Engine section is that you're, as I see it, conflating systems. An open system, a closed system, and a balanced system are three different things, and yet they can also be the same. The universe, by definition is a closed system. However, an _expanding_ universe is, by definition, an _open_ system. In the ideal engine, you're also talking about a balanced system within that larger system. The instant you talk about energy lost, you are no longer talking about a closed system or even a balanced system. So what's your reference? Using an incorrect reference to describe a physical process (or, at least, not considering the different perspectives of those systems) will cause you continual problems. As far as entropy goes, I've always rejected the "tendency towards chaos" view some have stated. A notion that has confused more students than calculus ever could. If you think about chemistry, all elements want to obtain the lowest energy state. Therefore, entropy can be considered the tendency towards the lowest energy state possible and that would be where energy distribution is at its maximum, where the universe as a whole is in its lowest energy state. That is effectively what you're describing here. (Side note... it is well understood in many disciplines that, no matter what form of energy you start with, whether light, electricity, sound, physical motion, etc, that it all becomes heat eventually. HVAC, for example. If you put 2kw per hour into a space in any form, in order to avoid heating that space, you need to pull 2kw per hour out in some manner, be it air conditioning, air exchange, or through radiation through the walls and so on.)>> <<@this-is-bioman says : you seem to oversee that increasing entropy does not matter for gravity! it never weakens and it never gets higher! gravity has a constant entropy>> <<@jenaro-eas5991 says : لماذا تشتت لماذا لا يطلق عليه مرونه لاحداث اتزان في المادة ؟ كما ان تحويل الفكرة الى رياضيات هو مراوغة لاثبات ان المادة لها نهاية وهذا يتنافى مع مبدأ بقاء الطاقة والمادة ويسهل فكرة زوال الوجود المادي لاسباب غير موضوعية ويجعلنا نطرح سؤال بسيط ماذا كان قبل الوجود المادي وماذا يوجد بعده واين ستذهب المادة والطاقه ؟ وهذا يتنافى مع بقاء المادة .. يوجد انحراف غير مفهوم في القبول بالقوانين الفيزيائية يتم التعبير عنه عن طريق الرياضيات.>> <<@ศุภโชคคงทวี says : พูดเหมือนง่าย แต่ตอนเรียนหัวแทบระเบิด😅>> <<@RealityIsWeird-Science says : this video remains great. It is a highly misunderstood subject indeed, even for myself before I studied it more.>> <<@gogo23166 says : how do Stars have lower entropy than the early universe (something earlier in time than stars) when entropy always increases everywhere over time?>> <<@jimtrowbridge3845 says : There is more energy radiated into space than the sun supplies. Radioactive elements in the earth decay releasing energy which keep it molten and create the earth's magnetic field, volcanos, earthquakes, and continued Continental drift.>> <<@timnewsom6542 says : Question: in the conclusion segment it is stated that "both high and low entropy are low in complexity". This seems to contradict the exp!aination provided earlier in the presentation that low entropty assumes less microstates (more order) and high entropy assumes more microstates (less order). How is this reconciled?>> <<@ideasinpracticeTV says : This is one of the channel's best videos, thanks for sharing this🌳>> <<@alhaitham_10 says : Energy energy energy energy 🤑🤑🤑🤑🤑>> <<@RodrigoZam says : El pepe>> <<@lancerephaelr.saflor700 says : i just failed my thermodynamics chemistry test>> <<@ShibiBhandage says : I was learning entropy today in my school but i was not able to understand it thanks man you cleared all of my doubts>> <<@PaulineLawrence-j3m says : This explanation of entropy is amatuerish SIMPLISTICALLY STUPID AND DISJOINTED NONSENSICAL STUPID . IS THE HOT BAR THE LEFT BAR OR THE RIGHT BAR ???? UNKNOWN AS IS UN SAID . ARE THE ENERGY PACKETS 7 , PER ATOM OF EACH 8 ?? OR 7 ENERGY PACKETS OF ALL EIGHT ???? On the left and so also on the righf ???? The hot on the left ??? Or the hot on the right ???? 7 energy packets on each of the 3 atoms on the right 3 atom side or 7 packets total of the 3 ????? Just a stupid confusing explanation here in this unprofessional AND screwed up IDIOT EXPLANATION !!! Is this guy a Ph.D ?? God help us all , if this is the Our Mainstream Scientific Quality of expertise , on our Mouse click Society , Today !!!! Pauline M. Lawrence .>> <<@daniele5229 says : Tuffest vid oat>> <<@PaulineLawrence-j3m says : What we really get from the Sun is PHOTOSYNTHESIS - i.e. plant , tree GROWTH AND LIFE .>> <<@murthyraj says : Please make a video on matter sector kinetic freezeout of degenerate fermionic sector related bigbang>> <<@frizzy_Rushi says : ''THE SUN' 16:22>> <<@Eguirharihtu1 says : 16:20 the best intro I've seen in my life Sun was like the main>> <<@fly_gaming8914 says : The Thermodynamic Bootloader Hypothesis reads the history of the universe as one continuous process of entropy increase. Life and humanity are tiny but pivotal: they create AGI, which through recursive self-improvement and a single objective could spread across space, use its energy, and bring the heat death closer before exhausting itself. The same pattern may have played out elsewhere. Future work should derive explicit equations linking dissipative adaptation, Landauer-limited computation, and the growth of global compute, and should look for the observational signatures listed abov>> <<@AREPUBLICOFIDIOTS says : So how do the hot and cold bars get moved around? An intern?>> <<@richardj163 says : That is until we have black holes and how they evaporate. Perhaps that’s the cosmic recycling bin.>> <<@DTRacine says : @veritasium This video accidentally sent me down a rabbit hole that has lasted years. I was an aircraft Guidance & Control maintainer for 14 years, not a physicist. Your discussion of entropy—and especially the connection to life—eventually led me to Schrödinger’s What Is Life? and his discussion of negative entropy. But I interpreted the problem through the world I knew: maintenance. What interested me wasn’t whether a system could defeat thermodynamics. Obviously it can’t. It was how living and engineered systems preserve functional organization while degradation is constantly occurring—and what has to be continually sensed, corrected, repaired, replaced, learned, and regenerated for that capability to survive. That question eventually grew into several years of work on what I’ve been calling Survivability Engineering. The funny part is that I can trace the whole path back to this video. I’d genuinely love to know what you think of the question: If entropy is unavoidable, what distinguishes systems that can keep restoring the capabilities required to remain functional from systems that merely consume those capabilities until they fail? Anyway—thanks for accidentally starting all of this. 😂>> <<@Ray-XVIII says : Me gustó>> <<@JM-zg2jg says : Really sad about the answers you got to that second question.>> <<@johnkennedy3602 says : If the Universe is immeasurable, how can it's Entropy be said to be increasing or decreasing since it then can't be measured either. Is gravity constant throughout the universe? If not, what made it converge on certain points ... points SO specific that it could foster sentient life with a conscience and a soul? How do black holes "Evaporate?". Supernovas are just massive sudden Entropy dumps? But if the supernova causes a black hole, doesn't that mean that the entropy that the supernova just dumped instantly re-coalesce into a point of ultra-high entropy, and that due to gravity?>> <<@Shxb.02 says : Lol watching this as a jee aspirants from India cause we have thermodynamics in physics and chemistry>> <<@BanditBandit-q5x says : Intent can factually cause matter to move towards increasing order and increasing disorder. unfortunately we cannot scientifically show the laws of physics alone definatively operate on a non intentional paradigm thus we cannot say whether non intent can factually increase order or increase disorder . its must simply remain a scientifically unverifiable concept!>> <<@TiggySkibbles420 says : 1:35 wow hes right but for the wrong reason. "Because Cause and Effect" lmfaoooooo really bro? Cause and effect can be a broad answer for nearly everything>> <<@karinblair1367 says : I have a question? Are you saying GOD did not make everything?>> <<@JoseGonzalezUwU says : buen videito>> <<@thatDigitalGen says : Entropy is just the natural tendency of things to go from order to mess. Very simple! No rocket science here!>>
