Humpty Dumpty quote #2 from wiki--entrophy--things falling apart. Entrophy of isolated system never decreases.

In science Humpty Dumpty has been used to demonstrate the second law of thermodynamics. The law describes a process known as entropy, a measure of the number of specific ways in which a system may be arranged, often taken to be a measure of "disorder". The higher the entropy, the higher the disorder. After his fall and subsequent shattering, the inability to put him together again is representative of this principle, as it would be highly unlikely (though not impossible) to return him to his earlier state of lower entropy, as the entropy of an isolated system never decreases.[51][52][53]
