This is happening inside you right now.
Kinesin is a molecular motor that “walks” along microscopic tracks inside your cells, carrying cargo from one place to another.
Each step is only about 8 nanometers long, powered by ATP.
Your cells have their own delivery system.
How an induction cooktop heats the pan.
Beneath the glass, a copper coil creates a rapidly changing magnetic field.
That field induces electrical currents inside compatible cookware. The pan’s own electrical resistance turns those currents into heat.
So the pan itself becomes the heat source.
How a skyscraper survives an earthquake.
Skyscrapers aren’t designed to stay perfectly still.
Features like base isolators, dampers, and flexible structural systems help absorb and redistribute energy when the ground moves.
That’s how tall buildings can sway in a controlled way instead of collapsing.
How noise-cancelling headphones actually cancel sound.
Noise-cancelling headphones don’t just block sound.
Microphones pick up outside noise, a processor creates an inverse sound wave, and the headphones play it back in real time.
When the two waves meet, they partially cancel each other out, which is why the noise around you sounds much quieter.
How your phone knows which way you’re holding it.
Inside your phone, tiny MEMS sensors track motion in real time.
The accelerometer senses gravity, while the gyroscope detects rotation, together helping your phone understand how it’s moving and oriented.
How Face ID sees your face in the dark.
Face ID uses Apple’s TrueDepth system to map your face with invisible infrared light.
A dot projector casts thousands of invisible dots onto your face, while an infrared camera reads the pattern back to create a 3D depth map.
That’s how your iPhone can recognize you even in low light, or total darkness.
@eabusad Si, me pasó, me arruinó el almuerzo, pero me pasó en el local de Cieneguilla, cuando fui con mi plata a alojarme, horrible esas modalidades de vender membresías.
