A Quote by Arthur Eddington
So far as physics is concerned, time's arrow is a property of entropy alone.

The arrow of time doesn't move forward forever. There's a phase in the history of the universe where you go from low entropy to high entropy. But then, once you reach the locally maximum entropy you can get to, there's no more arrow of time.
The weird thing about the arrow of time is that it's not to be found in the underlying laws of physics. It's not there. So it's a feature of the universe we see, but not a feature of the laws of the individual particles. So the arrow of time is built on top of whatever local laws of physics apply.
The increase of disorder or entropy with time is one example of what is called an arrow of time, something that distinguishes the past from the future, giving a direction to time.
The story of the universe finally comes to an end. For the first time in its life, the universe will be permanent and unchanging. Entropy finally stops increasing because the cosmos cannot get any more disordered. Nothing happens, and it keeps not happening, forever. It's what's known as the heat-death of the universe. An era when the cosmos will remain vast and cold and desolate for the rest of time the arrow of time has simply ceased to exist. It's an inescapable fact of the universe written into the fundamental laws of physics, the entire cosmos will die.
Whenever I want to represent or depict the official version, I will refer to them as 'mathematicians' or 'mathematical physicists' or idiots or something like that. There are no physicists in mainstream 'Physics.' From Newton to Einstein to Hawking, they are all just mathematicians as far as Science and Physics are concerned.
As far as the Lord is concerned, the time to stand is in the darkest moment. It is when everything seems hopeless, when there appears no way out, when God alone can deliver.
Our knowledge of physics only takes us back so far. Before this instant of cosmic time, all the laws of physics or chemistry are as evanescent as rings of smoke.
What differentiates time from space is that time does have a direction. In that sense it is different from space. I think that's certainly true that whereas spatial dimensions don't have direction or an arrow, time does. It runs from past to future. But I see that arrow of time as rooted in a deeper metaphysical reality, namely the reality of temporal becoming - of things coming to be and passing away. That is why time has this arrow. But it's not sufficient to simply say that time and space are distinct because time has a direction. The question will be: why does it have a direction?
So as far as Serbia is concerned, it does not have the right to influence the privatization or to claim any property, because Kosovo is a former member of the Federal Republic of Yugoslavia.
The right to private property meant at the same time the right and duty to be personally concerned about your own well-being, to be personally concerned about your family's income, to be personally concerned about your future. This is hard work.
The problem is that modern fundamental physics is so far from you and me. The mathematics has become so much more complicated that you need at least 10 years to understand it. Fundamental physics has advanced so far from the understanding of most people that there is really a big disconnect.
We are terribly imaginative, as far as technique in science is concerned. As far as changes in social arrangements are concerned, we lack utterly in imagination.
Time's arrow, we are told, is a one-way thing. . . Memory's arrow, like the needle of a compass too close to a lodestone, spins in all directions.
The fact that you can remember yesterday but not tomorrow is because of entropy. The fact that you're always born young and then you grow older, and not the other way around like Benjamin Button - it's all because of entropy. So I think that entropy is underappreciated as something that has a crucial role in how we go through life.
The powerful notion of entropy, which comes from a very special branch of physics … is certainly useful in the study of communication and quite helpful when applied in the theory of language.
It is to be emphasized that no matter how many [amplitude] arrows we draw, add, or multiply, our objective is to calculate a single final arrow for the event . Mistakes are often made by physics students at first because they do not keep this important point in mind. They work for so long analyzing events involving a single photon that they begin to think that the arrow is somehow associated with the photon [rather than with the event].
