"We change the rules," Leo grinned. "Enter . Imagine a drunkard’s walk in three dimensions. We can’t say where the glitter will be, but we can describe the distribution of where it might go. We stop looking for a single line and start looking at the 'drift' and the 'diffusion.'"

. But in Stochastic Calculus, the jitter is so violent that the square of the change matters too. Volatility isn't just noise; it’s a fundamental part of the equation’s DNA." An Informal Introduction to Stochastic Calculus...

"You’ve spent years mastering calculus," Leo said, tossing a handful of glitter into the churning water. "In that world, if you know the velocity and the starting point, you can predict exactly where a particle lands. It’s elegant. It’s clean. And in the real world, it’s mostly useless." "We change the rules," Leo grinned
