Kabsch algorithm

The Kabsch algorithm is a method to compare two things that look the same but might be a bit different. It helps scientists understand how things move and change shape.

Let's say you have two drawings of a square. They might look similar, but one might be a little bit stretched or turned compared to the other. How do we compare them to see how much they differ?

The Kabsch algorithm helps us do that. It works by finding the best way to move and rotate one of the drawings so that it matches the other drawing as closely as possible.

To do this, we pretend that the drawings are made up of lots of little points, like dots on a piece of paper. We use math to figure out how to move and rotate those points to make them match as closely as possible with the points of the other drawing.

Once we find the best way to match the two drawings, we can measure how much they differ from each other. Scientists can use this information to see how things change over time or how they respond to different treatments.

So, the Kabsch algorithm is like a magic tool that helps us compare things and understand how they move and change shape.
