The last time we took a break from any scientific considerations and blatantly entertained our minds with something equally crazy and inventive, there was just one easy option. Of course, it was ...

Ryan Duncan froze. He had just performed a new experiment examining common graphite—the stuff of pencil lead—but the results seemed physically impossible: Heat, which typically disperses slowly, had ...

The researchers conducted an experiment in which they were able to manipulate the speed of sound. They enriched the air composition with helium to increase the speed of sound, and under these ...

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 ...

A selfie taken by NASA’s Perseverance rover on September 10, 2021. Image: NASA/JPL-Caltech/MSSS Using a microphone, a laser, and some crafty mathematics, a team of scientists has measured the speed of ...

Scientists have discovered the fastest possible speed of sound, a zippy 22 miles (36 kilometers) per second. This exercise was largely theoretical: The researchers found that the answer, which is ...

The acoustic properties of an ultracold fermion gas have been measured either side of the superfluid transition temperature in an experiment that has been described as “near perfect” and “beautiful”.
