Entropy is a measure of disorder. Imagine a child's room: when toys are neatly arranged on shelves, entropy is low. But after a fun game, everything is scattered, and you can only restore order by making an effort. In the Universe, entropy always increases.

History

The concept of entropy was introduced by Rudolf Clausius in 1865, generalizing the second law of thermodynamics. Ludwig Boltzmann gave a statistical interpretation: entropy is related to the number of ways particles can be organized. James Maxwell proposed a thought experiment with a "demon" sorting molecules, which deepened the understanding of the connection between entropy and information. In the 20th century, Jacob Bekenstein and Stephen Hawking discovered that black holes have enormous entropy related to their area.

How it works

At the microscopic level, entropy grows because there are many more disorder states than order ones. Toss a handful of coins: almost never will all land heads up, because there are unimaginably many ways to scatter them mixed up. Similarly, gas molecules tend to fill the entire volume - that's the most probable, high-entropy state.

💡 If you shuffle a deck of cards, you will never return it to its original order just by shaking. That's entropy in action - disorder wins.
