. 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."

One student, Sarah, frowned. "So how do we track it if the math breaks?" 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." "So how do we track it if the math breaks

He turned back to the group, his eyes bright. "Now, let’s go inside and see why dt2d t squared equals zero, but dW2d cap W squared . That’s where the magic starts." It’s clean
