Stable bundle

Imagine you have a pile of toys and you want to carry some of them with you. But you don't just want to carry any kind of toys - you only want to carry toys that are "stable" and won't fall apart easily. This way, you won't have to worry about them breaking or spilling everywhere.

In math, a "bundle" is kind of like a pile of toys. However, instead of toys, a bundle is a collection of related objects that are all placed together. And a "stable bundle" is a collection of objects that are all related in a way that makes them very sturdy and reliable.

For example, imagine you are a scientist studying cells. You might want to group together all the cells that have the same function (like muscle cells or nerve cells). These cells would make up a "stable bundle" because they are all related and work together to do the same thing (like helping your body move or sending messages to your brain).

Overall, a stable bundle is just a fancy way of saying that a group of objects (or cells, or whatever else) are held together in a way that makes them very strong and reliable. It's like having a pile of toys that you know won't break or fall apart no matter how much you play with them!
