Geant4

Geant4 is like a super useful computer tool that scientists and engineers use to create pretend worlds where they can see how tiny particles move through different stuff, like atoms or radiation. It helps them make simulations and learn what happens when these particles bump into things like detectors or medical gadgets.

The tool also has lots of features to imitate how particles interact with matter. That means it can copy real-life situations where particles crash, scatter, or change, giving researchers important clues about how physics works.

Scientists can change the simulations to match their specific experiments or questions. Whether they're studying how particles act in a medical device or figuring out how space rays affect spaceships, Geant4 can be made to fit almost any scientific investigation.

It's important to note that the program lets researchers see the pretend paths of particles and how they interact with materials in a picture format. Visuals helps scientists understand how particles behave in their tests and makes it easier to analyze data.

The app is used a lot in different scientific areas, like high-energy physics, medical science, space exploration, and radiation safety. Because it can do so many things and can be changed to fit different needs, it's a really useful tool for researchers studying complicated physical stuff and events.
