is entropy problem easiest than quantum mechanics problem which one is more complicated to understand and to solve ?
No its not like this search on wikipedia there is a problem in entropy and another in quantum mechanics both aren't discovered yet . I simply want to know which one is easiest . Its not a homework in general is entropy hardest or quantum mechanics ?mfb said:What exactly does "entropy problem" and a "quantum mechanics problem" mean? Homework problems? Then it depends on the problem and your knowledge about entropy and quantum mechanics.
Surely if the solution to the problems you mention haven't been discovered yet, then there is no way to say which is harder and any answer would just be speculation. Anyway, you should link the aforementioned Wikipedia articles, so that anyone reading knows what you are on about.Peter25samaha said:No its not like this search on wikipedia there is a problem in entropy and another in quantum mechanics both aren't discovered yet .

-this is for entropy : https://en.m.wikipedia.org/wiki/Entropy_(arrow_of_time)Vagn said:Surely if the solution to the problems you mention haven't been discovered yet, then there is no way to say which is harder and any answer would just be speculation.

My question should be different then . Wich one of these 2 need more time to undertand well all about itmfb said:There is no fundamental problem with either of them. There are open questions, points where future research might improve our knowledge. That usually happens in many small steps, so you cannot quantify the effort necessary to advance
knowledge by a specific amount, not even for research done in the past.

Entropy is a measure of the disorder or randomness in a system. In physics, it is often used to describe the amount of energy that is unavailable to do work in a closed system.
The second law of thermodynamics states that in a closed system, entropy will always increase over time. This means that the disorder or randomness in the system will always tend to increase, and energy will become less available to do work.
In information theory, entropy is used to measure the amount of uncertainty or randomness in a system. The higher the entropy, the less predictable the system is. This relationship is also seen in the second law of thermodynamics, where the increase in entropy leads to less available energy and more disorder.
In quantum mechanics, entropy is used to describe the uncertainty in the state of a system. The more uncertain the state of a system is, the higher the entropy. This is related to the probabilistic nature of quantum mechanics, where the exact state of a system cannot be determined with 100% certainty.
According to the second law of thermodynamics, entropy will always increase in a closed system. However, in certain scenarios, it is possible to decrease or reverse entropy through external energy inputs. This is seen in processes such as refrigeration, where external energy is used to decrease the entropy of a system (e.g. cooling a room). However, the overall entropy of the closed system (e.g. the room and the refrigerator) will still increase.
