Disorder

Disorder is a term often associated with disease and abnormal behavior that destroys the repetitive patterns or ordering structure of a system. This word is sometimes associated with randomness.

Entropy is not about disorder

Entropy is a measure of unpredictability, not about disorder. Disorder is a measure of lack of order, where the passage of time is dependent on a unique path of evolution, where every step of the previous time point can not be changed at all, that means the ordering sequence is completely locked down by an immutable order. Therefore, entropy cannot be a measure of disorder.

Some example of Disorder related to Entropy

In a video:How Einstein changed time forever , Jim Al-Khalili stated that:

Entropy is the measure of the disorder of a system.

Relating disorder to entropy is a common semantic mistake made by science teachers.
