In 1991, scientists lowered 10 speakers into the water off of a remote Australian island in order to blast a monotonous 57 hertz tone from them for 10 days. Other researchers listened for the distant ...

Nuclear physicists proposed a method to measure the speed of sound characterizing matter created in nuclear collisions. Heavy nuclei consist of hundreds of protons and neutrons (belonging to a group ...

Millennium Space Systems developed two satellites for an experiment called DragRacer. The company will analyze the deorbit capability with and without a space tether. Credit: Millennium Space Systems ...

Using a microphone, a laser, and some crafty mathematics, a team of scientists has measured the speed of sound on Mars, in what is a scientific first and another cool finding made possible by NASA’s ...

Thought experiments can be extremely powerful; after all, pretty much everything that [Einstein] came up with was based on thought experiments. But when a thought experiment turns into a real ...

Researchers have devised a revolutionary new technique for measuring the microscopic elasticity of materials. Known as SRAS, the technology works by measuring the speed of sound across the material's ...
