Every sum you've ever written has Britain in it. 🇬🇧 Not the numbers. The marks between them. 👀 Equals. Times. Greater than. Less than. Infinity. Pi. Even the dot. 🧮 You've used them since you were five. Nobody ever told you who made them. 🤐 John Napier, Edinburgh. His neighbours swore he was a wizard. He made the decimal point normal. 🐓 Robert Recorde, Tenby. Sick of writing "is equal to", he drew two long lines instead. A year later he died in a debtors' prison. ⛓️ William Oughtred, Surrey. A village vicar whose little book made the times sign famous. Isaac Newton learned his algebra from it. ✖️ Thomas Harriot, the Thames. He drew the Moon through a telescope before Galileo did. Then he put it in a drawer. 🔭 John Wallis, London. He cracked the Royalists' codes in the Civil War. Then he drew a loop with no end. ♾️ William Jones, Anglesey. A farmer's boy who taught sailors on a warship. He gave the never-ending number its name. ⭕ Six people. Seven marks. Every sum you've ever written. They teach you the sums. Never the people who made them. 📚 Watch the full story. 🎥 It seems nobody else is counting. Help us put Britain back in the sum. Be part of us. ☝️🇬🇧 Be Proud Of Us. 🙏🇬🇧

A craftsman the Glasgow guilds turned away changed the world on a Sunday walk. 🏴󠁧󠁢󠁳󠁣󠁴󠁿🇬🇧 May 1765. James Watt, a Scottish instrument-mender, was crossing Glasgow Green. A broken steam engine had nagged him for 2 years: it threw away most of its heat. Halfway across the grass, the answer came. Condense the steam separately, keep the cylinder hot. His engines went on to power Britain's mills and mines. Today the world measures power in his name. The watt. No palace. A bench, a broken model, and a Sunday walk. We put the names back, free, for anyone who wants them. Want to learn more? If you can afford to, help us teach thousands their own history: Be part of us. ☝️🇬🇧 Be Proud Of Us. 🙏🇬🇧
