Abstract

In this note, we will explore the concept of diffusion and see how its inter-pretation has changed over time. We will discover why diffusion is such a useful and universal idea, one that always works. except when it doesn't! In those cases, "anomalous diffusion" comes to the rescue, offering a different and complementary perspective.
