entropy gradient

Entropy gradient refers to how the disorder or randomness (entropy) in a system changes across different regions or states. Imagine a room where heat spreads from a hot spot to cooler areas; the rate at which temperature differences diminish is akin to an entropy gradient. It's a way to measure how quickly or slowly entropy varies in space or time, indicating the direction and magnitude of natural processes tending toward disorder. In essence, it helps us understand where and how systems tend to become more disorganized or uniform.
