Brains, bodies, perception, and everyday physics.
Why do we see faces in things like outlets, car grilles, and clouds? It's your brain's face detector running hot, and science shows it goes deeper than you'd expect.
Why can't you tickle yourself? Your cerebellum predicts your own touch and cancels the sensation before it registers. Here's the weird science behind it.
What causes déjà vu, that strange sense you've lived this moment before? Leading brain science points to a memory 'misfire.' Here's the most likely explanation.
Why do we dream? Science has several leading theories, from memory sorting to emotional processing to threat rehearsal. Here's what we really know about dreams.
Why is the sky blue? The real answer is a story about sunlight, tiny air molecules, and a trick of physics called Rayleigh scattering, explained simply.
