What is an algorithm?
Algorithms decide what you see on social media, who gets a loan, and what music gets recommended to you. Here's what they actually are.
How do batteries work?
A battery is basically a controlled chemical reaction in a can — turning stored chemical energy into electricity on demand.
What is coding?
Every app, website, and piece of software was built by someone writing instructions in a language computers can follow. Here's what that actually involves.
What is virtual reality?
Strap on a headset and step into a different world entirely. Here's how VR tricks your brain into believing it's somewhere it isn't.
How does the internet work?
You use it constantly, but the internet is a genuinely mind-bending engineering achievement. Here's how data gets from anywhere to your screen.

AI can write essays, recognise your face, beat world champions at chess, and recommend your next favourite song. What's actually going on inside it?
What is a computer virus?
Computer viruses are named after biological ones for a very good reason. Here's how malicious software works and why it spreads.
How do search engines work?
