The subtlest experiment in quantum mechanics is also one of the simplest: send a stream of particles through two openings in a barrier, and you’ll produce an interference pattern because the particles ...

Scientists have long sought to explain how fish can sense the direction of sound, given the challenges that hearing underwater poses. An experimental study testing a variety of models now provides ...

sound waves cause air particles to vibrate back and forth ripples cause water particles to vibrate up and down Waves cause a disturbance of the medium through which they travel. This allows them to ...
