Mathematicians from the California Institute of Technology have solved an old problem related to a mathematical process called a random walk. The team, which also worked with a colleague from Israel’s ...

In this paper we present random walk based solutions to diffusion in semi-permeable layered media with varying diffusivity. We propose a novel transit model for solving the interaction of random ...

Here’s what you’ll learn when you read this story: Researchers used algebra and geometry together to solve an old random walk problem. Random walk ideas have informed everything from biology to video ...
