What are microscale interactions?

Microscale interactions are tiny actions that happen between very small things, like the building blocks of everything around us.

Imagine you're playing with tiny magnets, so small you can’t see them, and they’re attached to little balls. When two of these tiny balls get close, the magnets either push them apart or pull them together. That’s what microscale interactions are like: tiny forces that make things move or stay still at a very small level.

Think of microscale interactions as the invisible glue or push between building blocks. If you’re stacking blocks, sometimes they stick together, maybe because of something sticky on them, and sometimes they slide apart. Microscale interactions are like those sticky bits or sliding parts, but for things so small that we can’t see them with our eyes.

These tiny actions happen all the time in stuff like water, air, even your skin! They help explain why things feel soft, hard, warm, or cold, it’s just a bunch of tiny forces working together.
