An olog is like a big puzzle that helps us organize information.
Think about your toy box. When you first got it, all your toys were probably just jumbled together. It was hard to find the exact toy you wanted. But then your mom or dad probably helped you sort your toys by type. All the cars in one section, all the dolls in another, and so on.
That's kind of what an olog does. It takes a big topic and breaks it down into smaller pieces that belong together. For example, think about the topic of animals. That's a HUGE topic! But an olog might break it down into smaller categories like mammals, birds, fish, and insects. Those categories help us understand more about each kind of animal and how they are different from each other.
Ologs can be used for all sorts of things, like science, history, and even video games. They help us organize information so that it makes sense and is easier to understand.
