Entropy is all about disorder and randomness. Think of it like this: when you have a neat and tidy room, that’s low entropy. But as time goes on and things get messy—clothes on the floor, dishes in the sink—that’s high entropy.
In the world of energy, entropy measures how spread out that energy is. For example, ice in a glass has low entropy because it’s organized. But when the ice melts and the water spreads out, the entropy goes up. The second law of thermodynamics tells us that things naturally move toward more disorder over time.
In information theory, entropy measures uncertainty. A coin flip has high entropy because you don't know if it will land on heads or tails. But if you know it will always land on heads, that’s low entropy.
So, whether you’re looking at a messy room or thinking about how energy spreads, entropy is a reminder that things tend to get more chaotic over time. It’s a fun concept that helps us understand the world’s natural tendency toward disorder.
