El origen del "nudo": la unidad de velocidad que viene de una cuerda del siglo XVII

Did you know that when a pilot says "we're going 800 knots," they're using a unit of measurement invented by 17th-century sailors? In this video, we discover the surprising story behind the knot: how it originated from a piece of wood and a rope with real knots, why it's perfectly aligned with the Earth's geometry, and why modern airplanes still use it today. ⏱️ Chapters: 0:00 Introduction 1:03 The Problem of Navigating Without an Airspeed Indicator 1:39 The Invention of the Log-Steer 2:12 How Speed ​​Was Measured 2:37 The Origin of the Word "Knot" 3:01 The Earth's Grid 3:33 1 Nautical Mile = 1 Minute of Latitude 4:43 Why Do Airplanes Also Use Knots? 5:55 Conclusion 🪢 What you'll learn: What a log line is and how sailors measured speed without GPS Why 1 nautical mile = 1 minute of latitude (and why that's a stroke of genius) Why early pilots adopted knots and never abandoned them Cars measure speed like a human walks.
