Radically new and powerful things are being done with sound. Part of what I think is the growing trend of greater control of all information, light, energy, matter and magnetism. (ILEMM) Molecular ...

Students learn how sound waves are produced and transmitted. Students learn how sound waves are produced and transmitted and how frequency is related to pitch. The speeds of sound in different media ...

Scientists at the Advanced Science Research Center at the CUNY Graduate Center (CUNY ASRC) have discovered a way to control ...

Although few people ever get the chance to travel at the speed of sound, it is an alluring flight goal and an impressive technological feat. Though average people have flown at high speeds on ...

Researchers in Switzerland have found a way of using sound waves to manipulate objects in disordered environments such as liquids. Instead of trapping the objects as conventional optical and acoustic ...

For the first time, physicists have discovered a way to levitate large objects—as in, human-sized objects—with an acoustic tractor beam. Researchers from the University of Bristol became the first to ...

An atom could be made to emit an optical signal that is usually associated with another type of atom, according to calculations done by Andre Campos, Denys Bondar, Herschel Rabitz and Renan Cabrera at ...
