🌟 When Light Learns to Answer Back: The Quiet Science of Mirrors
From section: 🧪 Why mirrors are usually made of glass and metal… Light enters through the glass, reaches the metal, reflects from it, and then passes back through the glass to the observer. The glass protects the delicate metal film from scratches and chemical damage while also providing structural support so that the mirror remains flat over time.

💡 How an Incandescent Filament Turns Resistance into Warm Light
From section: When heat enters the visible spectrumThis dependence on extreme heat separates incandescent light from firefly bioluminescence, where a controlled chemical reaction produces photons with very little accompanying warmth.
