Courses

How the world economy works →

Understand the machine behind the headlines — why prices, jobs, money, and crises move the way they do — so the news stops being noise.

How the news actually works →

The news isn't a window onto the world — it's a product, shaped by choices at every step. Learn to read the choices, and the headlines stop reading you.

How financial markets work →

Markets look like a casino of flashing numbers. Underneath is a machine for turning savings into businesses and pricing the future — see it once, and the headlines read like a story instead of noise.

How companies are financed →

Earnings, IPOs, debt, buybacks, bankruptcies — business news talks about money flowing through companies, but never explains the plumbing. This course is the plumbing: where a company's money comes from, where it goes, and why a profitable company can still go broke.

How computers actually work →

A computer is a rock we tricked into doing arithmetic with electricity. This course walks the whole machine — from a single on/off switch up to a running program — so the box on your desk stops being magic.

How AI actually works →

Not a mind, not a magic box, not a database of answers — an AI is a machine that learns patterns from examples and predicts. This course builds one from the idea up, so the headlines stop being magic.

How stress and recovery actually work →

Your body runs on two settings — alarm and recovery — and modern life keeps the alarm on. See what's actually happening inside you, and tell what helps from what's only sold.

How energy and climate actually work →

Energy is never created or destroyed — only moved and degraded. See how that one rule powers the world and warms it, and learn to tell a real climate-energy claim from a sales pitch.

How space actually works →

Getting to space isn't about going up — it's about going sideways, fast. See why orbit is just falling and missing the ground, why astronauts float, and how to tell a real space claim from a sales pitch.

How biotech and longevity work →

What a gene actually is, how we read and rewrite it, how a drug is proven (and why most that work in a mouse fail in people), and what aging really is — so you can tell a real biotech or longevity claim from a sales pitch.

How your money works →

Why time is the strongest force on your money, what borrowing really costs, how to put savings to work without getting fooled, and how to decode a money offer.

How sports actually work →

Why a result is part luck, where the billions really come from, how leagues engineer their own fairness, and how to decode a confident sports claim.

How games actually work →

The design that makes a game compelling, the psychology that keeps you playing, and the business that turns all of it into money — so you can tell when a game respects your time and when it's built to extract it.

How food actually works →

How food is grown, moved, and priced — the biology, the farm, and the long chain to your plate — so you can see the system behind a meal and read a food claim for what it's worth.

How cybersecurity works →

How attacks actually work and how the defences hold — from passwords and phishing to encryption, two-factor, and spotting a scam — so you can stay safe online with judgement instead of fear.
