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.
🎲 Random explanations
See all →What would happen if the Sun disappeared?
The Sun is 149 million km away. It drives our weather, feeds all life, and holds the Solar System together. What would happen without it?
What was the Second World War?
The deadliest conflict in human history. Between 1939 and 1945, it killed an estimated 70–85 million people. Here's how it started and why it matters.
How do search engines work?
You type a question and get a million answers in 0.4 seconds. The system behind that is one of the most complex ever built.
How do rainbows form?
A rainbow is sunlight and rain working together to split white light into every colour at once. Here's the precise physics of how it happens.
What is the cosmic web?
Zoom out far enough from Earth and the universe stops looking like empty space — it looks like a giant spiderweb made of galaxies. Here's what that actually is.
What is a neutron star?
When a star dies in a supernova explosion, sometimes what's left is an object the size of a city but more massive than the Sun — where a teaspoon of material would weigh a billion tonnes.
What is venture capital?
Some investors don't want safe bets — they want to find the next big thing before anyone else and put millions behind it. That's venture capital, and it funds the companies that reshape the world.
What is interest?
Interest is the price of borrowing money — and the reward for saving it. Understanding it is one of the most useful things you can ever learn.
How does the minimum wage work?
The minimum wage is like a speed limit for pay — it sets the lowest amount employers can legally pay workers per hour.
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.
