The human ear detects sound. Sound waves enter the ear canal and cause the eardrum to vibrate. Three small bones transmit these vibrations to the cochlea. These bones transmit most efficiently ...

Kyoto Prize winners came to San Diego for this year’s symposium. Kyoto Laureate John Pendry talked about the theory of ...

Light is a type of electromagnetic radiation that can be detected by the eye. It travels as a transverse wave. Unlike a sound waves, light waves do not need a medium to pass through, they can ...

For centuries, the reflections of light or sound have been theorized. Scientists have always thought of another variable: ...

Scientists have been unable to confirm the existence of time reflection due to the amount of energy required to create a ...

In the future, this method could also be used in technical applications with electromagnetic waves. Water, light and sound waves usually propagate in the same way forward as in a backward direction.

Let's go back to those sound waves from before. See, sound waves, like light waves, have peaks and valleys. Noise-cancelling headphones have their own built-in microphone. And when the headphone's ...

Picture yourself standing in front of a mirror, but instead of seeing your face, you see your back. As odd as this may sound, ...
