The electromagnetic spectrum represents all possible radiations, ranging from very long radio waves to highly energetic gamma rays. Within it, visible light is minuscule—just a...
Marine caves often function as natural resonance chambers. They typically have narrow and elongated shapes, irregular and damp walls, everything needed to amplify sounds. When...
Marine bioluminescence is a natural phenomenon where certain organisms emit light through chemical reactions within their bodies. Most of them live in the dark depths...
Glaciers function a bit like a giant thermometer: as soon as the temperature rises, it is immediately visible in their behavior. When it gets warmer, glaciers melt...
Snails make their shell from a special organ called the mantle, which gradually secretes calcium carbonate. This mantle produces the shell following a regular curve, giving the...
A Fresnel lens is based on a simple optical principle: it concentrates light using a structure cut into thin concentric rings. Instead of using a...
The phosphorescence of mushrooms primarily comes from small molecules called luciferins, which react with specific enzymes, luciferases. This chemical reaction emits a soft visible light, usually green...
The Earth's magnetic field is somewhat like a giant magnet tilted slightly at the center of the planet, with two poles, north and south. But...
When it's hot, the heat strongly promotes the evaporation of water. The water contained in the thin film of soap bubbles evaporates much faster in...
This phenomenon called thermochromism is simply the ability of certain liquids to change color when their temperature rises or falls. Basically, heat makes the molecules...
