Ever wondered how a microwave actually heats your dinner? How Wi-Fi gets through walls? How an MRI sees inside you without cutting you open? How {things} Work is a field guide to the machinery of modern life - short, plainspoken explainers about the everyday objects, systems, and ideas that quietly run the world. Every topic has three reading depths. - The short version - a paragraph that answers the question. - Go Deeper - a more technical pass, already prepared. - The Full Picture - edge cases, context, and broader connections. What's inside the first release: - Around 200 topics across 30 categories - from home appliances and transport, to your senses, the weather, money, materials, AI, and more - A quick quiz at the end of each topic, so the details stay - Bookmarks for the ones you want to come back to - Source links at the foot of every topic Built to read calmly. No accounts. No ads. No tracking. Works fully offline once installed. Read on the train, in bed, or in the kitchen while something's in the oven. For the curious - and for anyone who keeps getting asked "how does that actually work?"
