"disorder"

a clump of ice in space will have low disorder=low entropy. if that clump of ice you smash it into pieces it will now be in a state of higher disorder=higher entropy

yes this has consecuences for the universe that are not completelly clear. like why does it form low entropy "clumps" in his way to a high entropy final rest (supposedly according to current theories....)

So I can only claim to know anything about entropy from a material PoV, even then I'd doubt the accuracy of it.
It's a bulk substance taking on properties of another bulk substance when heat increases.
Like you have a solid chunk of silver and copper not touching in a furnace. You will get more molecules of silver on the copper and vice-versa as you increase the temperature in the furnace.
From what I can tell, this is from heat breaking down the molecular bonds and increasing the speeds of the individual molecules that split from the bulk which encourages intermingling of the two disparate molecules.

Entropy is the ratio between the amount of information to define something and the actual information contained within it. For instance, uncomputable numbers have high entropy as they can only be defined by axioms, meaning they have a 1 to 1 ratio of axiom to individual number.

Here is my 100% guaranteed proof for entropy:

There is no such thing as a true "black box", it doesn't exist. You can try as hard as you want, every single object or container will have a radiation signature, if only a small one.
This means that any closed system will always be emitting radiation.

Which means that radiation must always be spreading out through the universe, getting ever more diffuse. Since energy is conserved, and this is always happening no matter what, it means that entropy always increases

Entropy is the amount of ways energy can be distributed within a system. A good analogy to conceptualize this is money. Lets suppose you start with a 100 dollar bill and you have to split it between 30 people. The simplest way is to simply give one person the bill, resulting in 30 possible configurations. The outcome with the most configurations is the split the 100 dollar bill into one dollar bills (excluding coins), resulting in a vastly greater number of configurations. Entropy is considered at a minimum with the smallest number of configurations and at a maximum with the most configurations.

Entropy is the differentials in a system with order and or disorder. Nothing more than that. At least I cannot say it better. Try to google and you'll see.

>>10877426
Consider a probability distribution over a finite alphabet A, with corresponding set of finite words denoted A*. We say that A can be asymptotically coded with rate R if there exists a mapping from A* to the set of finite bit strings with the property that for any [math] \epsilon>0 [/math] and any N sufficiently large, it is possible to map every word in A* of length n>N to a bit string of length [math] n(R+\epsilon) [/math] such that the original word can be uniquely reconstructed from the bit string with probability at least [math] 1-\epsilon [/math]. The entropy of the distribution is then the minimal value of R for which A can be asymptotically coded with rate R. See Shannon's source coding theorem for more details.

What about predictable randomness, like the white noise on an unused television frequency?
Is it high or low entropy?
