ELI5: Explain Like I'm 5

Neutron transport

Neutron transport is like a kind of game. Imagine a big ballroom with lots of people in it. All the people in the room represent neutrons (tiny particles of matter). The people can move around and bump into each other inside the room, just like neutrons do. But the neutrons are special - they're invisible! That means you have to use math to figure out where the neutrons are going. We use neutron transport to figure out how the neutrons move through different materials, like metal or water. It's like a detective game - the math helps us figure out where the neutrons will move and where they'll end up.
