The number of microstates (N) of a system corresponds to the total number of distinct arrangements for “e” number of electrons to be placed in “n” number of possible orbital positions. N = # of microstates = n!/(e!( n-e)!) ) = 30.

A microstate or ministate is a sovereign state having a very small population or very small land area, usually both. Recent attempts, since 2010, to define microstates have focused on identifying political entities with unique qualitative features linked to their geographic or demographic limitations.

What are “Microstates” and give 2 examples in Europe and 2 examples in Asia? A state with a small population or land area.

A microstate is one of the huge number of different accessible arrangements of the molecules’ motional energy* for a particular macrostate. Each specific way, each arrangement of the energy of each molecule in the whole system at one instant is called a microstate.”

The diagram below illustrates each of these distributions that we have mentioned. You can see that there are 10 total possible distributions (microstates).

The key difference between microstate and macrostate is that microstate refers to the microscopic configuration of a thermodynamic system, whereas macrostate refers to the macroscopic properties of a thermodynamic system.

All microstates are equally probable, but the macrostate (H, T) is twice as probable as the macrostates (H, H) and (T, T).

The probability of finding any given macrostate is the ratio of the number of its microstates to the total number of possible microstates. For example, the probability of getting 2 heads is W (n)/ W (all) = 3/8.

The number of microstates (multiplicity) in each term is (2S+1)(2L+1).

Key Takeaways: Calculating Entropy

1. Entropy is a measure of probability and the molecular disorder of a macroscopic system.
2. If each configuration is equally probable, then the entropy is the natural logarithm of the number of configurations, multiplied by Boltzmann’s constant: S = kB ln W.

Entropy is measured between 0 and 1. (Depending on the number of classes in your dataset, entropy can be greater than 1 but it means the same thing , a very high level of disorder.

We can calculate the amount of information there is in an event using the probability of the event. This is called “Shannon information,” “self-information,” or simply the “information,” and can be calculated for a discrete event x as follows: information(x) = -log( p(x) )

Information gain is calculated by comparing the entropy of the dataset before and after a transformation. Mutual information calculates the statistical dependence between two variables and is the name given to information gain when applied to variable selection.

Entropy is basically the number of ways a system can be rearranged and have the same energy. Chaos implies an exponential dependence on initial conditions. Colloquially they can both mean “disorder” but in physics they have different meanings.

The greater the information in a message, the lower its randomness, or noisiness, and hence the smaller its entropy. Since the information content is, in general, associated with a source that generates messages, it is often called the entropy of the source.

The logarithmic measure is more convenient for various reasons: It is practically more useful. Parameters of engineering importance such as time, bandwidth, number of relays, etc., tend to vary linearly with the logarithm of the number of possibilities.

In information theory, the information content, self-information, surprisal, or Shannon information is a basic quantity derived from the probability of a particular event occurring from a random variable. The Shannon information can be interpreted as quantifying the level of “surprise” of a particular outcome.

To do the inverse (i.e. to calculate surprisal in bits given probability) you can use a calculator to try different bit values in the equation p = 1/2#bits until you get the correct probability, or you can use the logarithmic relations: s = ln2[1/p] = ln[1/p]/ln[2].

entropy, the measure of a system’s thermal energy per unit temperature that is unavailable for doing useful work. Because work is obtained from ordered molecular motion, the amount of entropy is also a measure of the molecular disorder, or randomness, of a system.

noun. the act of surprising. the state of being surprised. a surprise.

Linguistic prediction is a phenomenon in psycholinguistics occurring whenever information about a word or other linguistic unit is activated before that unit is actually encountered. Linguistic prediction is an active area of research in psycholinguistics and cognitive neuroscience.

The information content, entropy, of a particular symbol, x, is calculated from the probability of its occurrence using the following formula. If ( ) 0 p x = then ( ) 0 H x = by definition. Remember that all probabilities must obey the following rule.
