🌑 Shadows Across the Solar System: How Eclipses Unfold Beyond Earth
From section: 🔭 The geometry that shapes every eclipseEvery eclipse begins with a simple arrangement: a light source, an object that blocks the light, and a surface where the shadow falls. In our Solar System, the Sun is the light source, planets and moons are the objects that cast shadows, and the surfaces range from rocky ground to swirling clouds.

🚂 Echoes of Steam, Currents of Steel: Train Engines and the Rise of High-Speed Motion
From section: 🔬 The physics of motion: friction, lift, and air resistance… Maglev changes that relationship by lifting the vehicle away from ordinary rolling contact, reducing mechanical friction and wear. Low-pressure tube concepts go one step further in theory by lowering air pressure around the vehicle, reducing drag as well as contact-related resistance. …
