What are in situ measurements?

In situ measurements are like taking notes while you’re playing your favorite game, you're right there in the action.

Imagine you're in a big park, and you want to know how fast the swings go when kids push them. Instead of watching from the sidelines, you jump on one of the swings and feel how it moves. That's what in situ means, in the place where things happen. It’s like being inside the swing, not just looking at it.

Think of a detective who wants to know what happened at a crime scene. If they're doing an in situ measurement, they’re right there at the scene, touching the clues, counting the footsteps, and maybe even tasting the cake that was left behind. They don’t just look from outside; they’re in the middle of it all.

This kind of measuring is super useful because it shows exactly what's happening where it happens, no guesswork or extra steps needed!
