### Modeling a list with a tunable degree of disorder/shuffling

Imagine we have a list of ordered numbers $L = (1, 2,\dots, N)$. I want to add an arbitrary amount of "disorder" to that list. For instance: Adding a little bit of disorder would permute a few ...

### Confusions regarding entropy

Help, I am terribly confused about entropy. On the one hand, I am taught at school that a substance such is an ice/solid has a lower entropy than its gaseous equivalent and that a process such as ...
I studied thermodynamics and I saw the following definition for entropy: $$\Delta S = \int_1^2 \frac{\text{d}Q}{T}$$ that we use to calculate $\Delta S$ for different types of transformations. In ...
