There’s a simple way to measure the speed of sound. It’s low tech and unimpressive, but you get to blast an air horn. How many times can you say that you’re using one for science and not sheer ...

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 ...

You might think that if you have a need to measure the speed of a projectile that is too fast for your high-speed camera, you would have to invest in some significantly expensive equipment. That was ...

Researchers have measured the speed of sound in pure iron under pressures similar to those that exist at the Earth’s inner core boundary. The result suggests that this region of the core may be ...

A new Tel Aviv University study has revealed, for the first time, that bats know the speed of sound from birth. In order to prove this, the researchers raised bats from the time of their birth in a ...
