Self-consistent for Dummies

Self-consistent is a word that we use to describe something that makes sense within itself. It means that all the pieces or parts of something fit together in a way that is logical and coherent. Imagine you are putting together a puzzle, and each piece has to fit perfectly with the others for the picture to make sense. That's exactly what self-consistent means, like all the pieces of a puzzle coming together.

In simpler terms, when something is self-consistent, it means that there are no contradictions or conflicts within it. It's like when you're telling a story and the plot flows smoothly from one event to the next, without any gaps or inconsistencies. Everything fits together perfectly, just like in a well-designed, complete jigsaw puzzle.

When we talk about self-consistent in a scientific context, it means that a theory or a set of scientific principles are in harmony with each other. It's like all the ideas and concepts within the theory or principles don’t contradict each other. They work together seamlessly, just like all the gears in a clock moving in sync to tell the correct time.

Think of it this way: if you're baking a cake, and the recipe says to add flour, sugar, eggs, and butter, but you also decide to throw in some tomatoes and fish, that wouldn't be self-consistent. The ingredients don't go together and would create a strange and probably not very tasty cake. However, if you follow the recipe exactly, adding all the right ingredients in the right amounts, your cake will be self-consistent. All the flavors will blend together perfectly, and you'll end up with a delicious treat!

So, to sum it up, self-consistent means that something is coherent and logical, with all its parts fitting together smoothly, without any contradictions. It's like a well-crafted story, a perfectly assembled puzzle, or a recipe that uses the right ingredients in the right proportions.
