- 🗺️ Maps are not just physical objects but mathematical models of reality, representing complex concepts beyond simple geographical depictions.
- 💡 The core challenge in mapmaking is projecting a 3D spherical Earth onto a 2D flat surface, a process that inherently involves distortion of distances or angles.
- 🌍 Projections like the Mercator projection, while useful for navigation, can significantly skew our perception of the size of continents, making Greenland appear larger than Africa.
The Paradox of Measuring Coastlines
- 📏 The length of a coastline is not a fixed number but depends on the scale and method of measurement, meaning it can be as long as you want it to be.
