In math and physics, 'fluxion' describes a rate of change or flow, like the speed of a river or the increase in population. It's similar to the idea of 'derivative' in calculus. Imagine a faucet: the fluxion is how quickly the water is flowing. Think of it as something dynamic versus static. It isn't as commonly used today, but it represents a fundamental concept in understanding how things change over time. Basically, it's all about movement and transformation.
