Big ideas.
Simple words.
We explain complicated things so clearly, a 10-year-old could understand them — and honestly, most adults couldn't explain them any better.

How it works
Three rules. No exceptions.
No jargon. Ever.
If a word wouldn't make sense to a 10-year-old, it gets swapped out for one that does.
Use real analogies.
Every hard idea gets connected to something you already know — pizza, Minecraft, whatever works.
Keep it honest.
Simple doesn't mean dumbed down. We never sacrifice accuracy — we just refuse to be confusing about it.
Got a question?
There are no stupid questions. If you don't understand something, chances are loads of other people don't either.
