Negative pressure is a rare and challenging-to-detect phenomenon in physics. Using liquid-filled optical fibers and sound waves, researchers have now discovered a new method to measure it. In ...

For centuries, the primary way that astronomers studied outer space was through sight. But just ten years ago, scientists ...

The merger of two black holes is a momentous event, revealing the wildest and most extreme configurations of space, time and ...

WELL, BACK HERE, MIDDLE SCHOOL STUDENTS ARE LEARNING TO BEND LIGHT AND SOUND WAVES. IT’S NOT JUST FOR SUPERHEROES. EIGHTH GRADERS AT BEEDLE MIDDLE SCHOOL EXPLORED THE LUMINARIUM TODAY. THEY DISCOVERED ...

In the ETH experiment, self-oscillations (blue-red) cause sound waves (green, orange, violet) to travel through the circulator only in one direction. Credit: Xin Zou Researchers at ETH Zurich have ...

A scattering-invariant mode of light is generated by a spatial light modulator. This modulated beam propagates through free space (top) or a strongly scattering medium (bottom) such that the pattern ...

We are surrounded by waves. tiny vibrational waves transport sound to our ears. Light waves stimulate the retinas of our eyes. Electromagnetic waves bring radio, television and endless streaming ...

A study published last month by University of Minnesota mechanical engineering researchers has the potential to make waves – ultrasonic waves, to be exact – in fields like surgery and manufacturing. U ...

As a physical quantity pressure is encountered in various fields: atmospheric pressure in meteorology, blood pressure in medicine, or even in everyday life with pressure cookers and vacuum-sealed ...
