The second law of thermodynamics is explained but is it really ! What is entropy?! Interesting because with a small amount of math and Greek and blocky Universe with devil!👨💻

Second law of thermodynamics broken?
A group of Japanese researchers has just managed to accomplish something that can tear down some of today's physics and lead to the creation of perpetuum mobile type II. By using quantum entanglement they managed to break the second law of thermodynamics.
A few years ago, the Japanese created an experimental version of Maxwell's demon, creating a kind of passage in which a barrier was placed that allowed atoms to jump to a higher level and prevent them from falling down.
As a result, the atom slowly climbed the mountain - without adding any energy to the system.The Japanese closely followed the position of the atom all the time to know when to raise and lower the barrier. So if you take into account this monitoring system and the information it generates - it all makes sense, although it can be considered an extraordinary curiosity that in the experiment they managed to convert the information into energy.
In other words - we obtain information for free - and since, as the previous experiment proved - we can transform this information into energy - quantum entanglement gives us an advantage that the second law of thermodynamics did not provide.
This means that the laws of thermodynamics depend not only on classical phenomena and information but also on quantum effects. For now, it all works only (and up to) on paper and the race continues who will be the first to recreate it in the real world

"Entropy can be viewed as the number of possible arrangements of the (quantum) state of your system. If you have more options for how you could arrange your system so that it remains identical, you have higher entropy than if there are fewer options. A room with 20 different regions at 20 different temperatures has a lower entropy than a room where every location has the same temperature.

They found that the change in entropy was negative at intervals of a few tenths of a second, showing nature running in the opposite direction. In this case, the ball obtained energy from the random movement of the water molecule - on a small scale, the equivalent of a cup of tea heats up. But at intervals longer than two seconds, the overall positive entropy change was measured and normality was restored.
The team says their experiment is the first evidence of a violation of the second law of thermodynamics at significant time and length scales.
