The Startling Reason Entropy & Time Only Go One Way!

🤔 2 different elemental gasses H&O in a 5gal 🪣 = how much water 💧 in 🪣👊🧐🤘💯🇺🇸🤘🤣🤘

something that i believe is that time can still not be defined by entropy because as you talked about change. Change in itself can't exist without time and entropy as well increases with time and not the other way !

Time is the counting of acceleration. Walk 100 steps in one direction and the back 100 steps. Does your counter read 0 or 200? Even if you walked backward and your counter subtracted, it would still be 200 actual steps.
Acceleration is always additive.

Another question: " Why gravity goes one way?" If the time goes backward gravity would go backward!?

i always wanted to learn in this way but at that time i have no resources no money no guidance—

Very well presented. It was very important that this video pointed out that the words "entropy" and "disorder" are interchangeable in meaning.
The discovery that the disorganization of a system is directly related to the probability of such a system coming into existence by random processes was a great breakthrough. And it gives the formula for how to calculate this probability. It not only shows what chemical and physical reactions will likely take place spontaneously under normal conditions, but also shows us that the overall entropy or disorder in the universe is increasing with time.
However, Boltzmann's formula is a description of what is observed. The idea that probability is the causative factor in the second law of thermodynamics is a philosophical position. An equation describes what is observed and what to expect under certain conditions. It does not tell us why such a law in our natural world exists, nor why it follows the mathematical pattern that it does, nor by what means such a law came into existence.
"The heavens shall wax old as doth a garment". This was declared in Scripture long ago. This increase in disorder, as a layman like myself understands it, is an aging process, and our common everyday observations of the world around us shows that it is true for both living and non-living systems.
If you were to start a plum bob swinging back and forth, you would notice that each swing was becoming less and less. Even if you were to put the pendulum underneath an evacuated bell jar, the dying away of the motion, while taking place at a slower rate, would still be observable. In like manner, if you took an original photo and made multiple copies of it, each copy being made from the proceeding copy, it would be noticed that the copies would look worse and worse the further away you got from the original.
The second law of thermodynamics shows us that nothing in our universe works with 100% efficiency. Energy is expelled from a process in the form of heat, which my physics textbook calls "disordered energy". While the total amount of energy is still the same, it has been spread out into other less usable forms just as explained in this video. That is why it is impossible to create a perpetual motion machine.
What are all living things physically speaking? They are genetic copies of copies of copies going back further and further in time. The second law of thermodynamics makes a prediction---namely that the genetic copying process is not going to take place with 100% efficiency and that this inefficiency of genetic transfer from generation to generation has to show up somehow. And it does. As detrimental mutations. As to any supposedly beneficial change, it is necessary to be able to rule out the possibility that this is not a reverting back to a previously undamaged condition, especially since there is a backup to the genetic code which is incorporated into the cell with a computer-like sum check process kicking in to minimize the harmful effects of damaged genes being transmitted to the next generation of living things. This shows that the gene pools of all living things in our universe are aging.
The theory of evolution should have been discarded when the mathematical understanding of the second law of thermodynamics was discovered. The fact that it hasn't been is a testament to the fact the scientific world is not as objective as advertised.

Another great vid from Arvin, but I have great difficulty understanding the use of the word "entropy", meaning moving from an organized state to a disorganized state. If the universe moves toward thermal, gravitational, energy, and particle equilibrium, wouldn't that be a perfectly organized state? Just because it doesn't include us doesn't mean it would be disorganized.

If big bang lead to inexorable increase in entropy then why are planets well organized 🤔

this can be explained in ambaTENET

Good question. Why entropy goes from order to disorder only? Why there are more disorder states than order state in the universe? Why big bang ❗️ is the reason for moment of time and disorder?
Is that true NOW! After James telescope data?

Time is just memory of change that happens when order becomes disorder and Vice versa.

❤🧠❤

Good explanation. I just don’t like the way scientists are using probability to make extraordinary claims. When the universe came into existence it has all the possible probabilities, as probabilities are manifested and become observables/measurable they become reality. Reality is the perception of the interactions of the energy fields in the universe. There are different means to perceive energy fields, so reality is not the same for all perceivers. If there is no perception, the energy fields are in the state of existence/being.

Anyway thanks

As long as there is expansion it is one way but there is possibility of other way in case of contraction of this cyclic universe

You're a great man..I'm one of your very earlier followers

Nice explanation of entropy and maybe intuitive for some people, connecting entropy to probability of states as Boltzmann has done first. In this paradigm though we cannot explain the Saturn rings for example. But one can do better. One can go beyond probability of states to measure theory to quantify chaos. Kolmogorov has used measure theory to define Kolmogorov complexity which has Boltzmann entropy as a special case in its belly. Kolmogorov complexity and the KAM theorem are able to explain why there are unstable chaotic orbits of the Saturn rings between the stable orbits. Further, classically there is no explanation for the second law of thermodynamics. It’s just an unexplainable law. Roger Penrose claims the fact that entropy grows in the universe stems from a symmetry breaking at the Big Bang. Other universes may thus not have a second law of thermodynamics. By the way, there are ways where two liquids unmix, eg the Belousov Zhabotinsky reaction. I loved the look on the face of the students when I showed it during my lectures. There is more to physics than equilibrium Boltzmann type thermodynamics. Think of your pencil, or the physical pendulum. They show bifurcation and chaotic behavior.

I understood and then I misunderstood 😔

Statistics and probability are very rigorous subjects.

Statistics is a model. It’s a tool to help us comprehend nature and totally subjective to the mind of humans. It is not a “why”. It did not convince me as one audience, Mr. Arvin.

Therefore, if we exist, then life elsewhere is likely. Life is very probable indeed!

I'm shocked with just how intelligent he is.

Time is also probability function of events to happen.Universe is expanding so is the probability curve of possibilities of an electron to be present at one particular moment becoming flatter or other words probability of finding it in the universe decreases giving rise to time.Xaxis space y axis time.

Time is merely the motion of matter in space. Panta rhei.

Thanks for the probability definition. I still cannot agree to the concept of "work" as it is not a neutral term. I think physics should be described neutrally.

Thanks for the lovely and simple explanation. I can use this to explain to those I discuss this with.

So, if this "force" (or 2nd law of thermodynamics) is the tendency to increase entropy, transforming energy into one that has less potential to do work, what is the opposite?
What's the force that concentrates energy and increases its potential to do work? 

I once read that life is the opposite of entropy. The symmetry of there being 2 opposing forces makes some scientific sense.

Thank you very much, your explanations is simply perfect.

Fine, but what is work? Who decides what is useful and what is not???

from our human perspective time moves 1 way. Infact i even hate to say anything about time because i am pretty confident that we as human don't even have the first clue what time really is. I mean I know that we don't know what time is but what i am saying is that in all of our ideas, theories, concepts, movies, wildest imaginations we have zero clue what it is. It is something we have not thought of yet or maybe can't even think of. These videos are great for showing what we think is correct and for what we observe but as for actual truth we are not even close.

It's not physics, but probability that governs Entropy. Nice vidéo. Thank you for work.

This was essentially a very good introductory lesson on statistical thermodynamics. I never really understood some thermodynamics concepts until I took a course on statistical thermodynamics as a grad student.

"Can entrophy be reversed?"
"Insufficient data for meaningful answer."

I understand your point re entropy but if time could go backwards like the 4D model Einstein gave, can entropy not run backwards if you look at the reference frames in reverse order?

An earthquake can make a pencil stand up

I think there's only two finite directions in the universe. Something is either going into a dimension or out of a dimension. Dimensional organization. On one hand entropy would seem more chaotic but spacetime itself is becoming more organized and predictable.

Life would seem to undercut these principles, would it not? How about the big bang? Yes, each living thing and the universe itself are winding down, but how probable was their winding up?

Damn. That just blew my mind.

Well done and my Freshman Chem/physic classes will enjoy it W0000t!

Reading one of Asimov's short stories about the question on entropy.

I always loved the idea that after several cosmological decades. After protons decayed, after the universe has grown cold and dark. After an incalculable near infinit amount of time, an event so impropbable as to have a 0.0 and near continous zeros following it before a 1 finally appears. Where at that point entropy resets to what is was at the beginning of the big bang. "Let there be light" happens again, and another big bang or something similar occurs.

It is so surprising, that putting the car in reverse doesn't make time run backwards.

It is of no use for any lay person to hear abstract concepts (time, entropy, disorder) being related to one another with none of them being defined with reference to the only tangible entity that is immediately accessible to, and enables survival of, every individual on this earth, THE PLANTS.

Unless knowledge can be related to them in such ways as to help influence their growth, it cannot be called as such, as they are the only means for sustenance of all life on this earth, and as a consequence, in the entire known universe.

Mixing fluids is not a disorder but balance and order. The pencil falling down is due to gravity.

This was amazing. Until now I'd never been able to make sense of the concept of "increasing entropy in a system" which as a science concept seemed hopelessly vague. Explaining it as a function of end state probabilities made the connection for me. Thank you for that. As a side note, I once dropped a penny onto a table where it bounced a bit until finally coming to rest on edge. I couldn't believe my eyes. In amazement, I left that penny sitting there for maybe 20 minutes. But as you explained--improbable, not impossible.

Thermal dynamics 2nd law cannot be regarded as fundamental physical law. Man-made order is not necessarily nature’s order. What are the entropy for graphite and diamonds? What’s the difference of entropy between a life and it’s dead body? Take human body as a close system example, how to prove the whole body’s entropy is increasing, while the stomach is digesting food? What is the proof that the entropy of the body can only increase in every picosecond?

I don't believe entropy & time are connected in this manner; namely, because of Accelerating Cosmic Inflation & the Cosmological Horizon -- this horizon effectively strips the Entropy Law of validity, as well as any conclusions derived therefrom. For instance, we could say hypothetically that Entropy Law is valid, except over 90% of the Observable Universe has already crossed the Cosmological Horizon. After which, there is no way to ascertain entropy; the entropy of the observable Universe, at an increasing rate, is becoming empirically unfalsifiable. Indeed, some ~60K Stars every second continue to vanish beyond the Cosmological Horizon. You cannot know what entropy looks like beyond that point. The Law of Increasing Entropy over time is, therefore, merely a preference to say that's how Entropy does indeed work. But maybe that is just based on your preference for a Universe founded on Causality. Again, that cannot be an empirically induced absolute fact of how the Universe operates. Perhaps the flow of Entropy is just as an arbitrary preference in a Universe that is fundamentally based on contiguity rather than causality.....(?) It would seem to be equally plausible...

How can people keep saying that the entropy of the universe increases when things are constantly becoming more ordered and energy is being concentrated all the time. Seriously people you forgot what science is. You’re taking an idea and deciding what’s possible in the real world instead of studying what the real world does and forming an idea. None of these videos actually scientifically study a system to see if entropy is increasing. They just say “your room won’t clean itself spontaneously” thus entropy. Actually study that scenario and calculate every single energy input and output and then see what is this case. Your just making assumptions and drastically simplifying the situation. Can we do real science please?

Entropy proves creation. Entropy plus anthropic proves A loving God who created EARTH for humans.
