Okay kiddo, do you know what a computer program is? It's a bunch of instructions that tell a computer what to do.
Now, in the world of computer science, there's a special kind of program called a Harris functional. This program is named after its creator, Mark Harris.
The Harris functional is designed to solve complex problems, like how to create realistic graphics in video games or simulations. It does this using math and algorithms, which are like recipes for solving problems.
Think of it like a really special kind of calculator. You give it some inputs or data, it does some calculations, and it gives you outputs or results. But unlike a regular calculator, the Harris functional can handle really big and complicated problems.
So, the Harris functional is a tool that helps computer scientists solve tough problems and create amazing things like realistic graphics in video games. Pretty cool, huh?
