Physicists create a quantum rotor that makes 60 billion revolutions per minute
“A nanoparticle has been created by scientists, shaped like a dumbbell and made of silica, and they have successfully set it spinning in a vacuum at 60,000,000,000 revolutions per minute. Yes—60 billion.
That makes it the fastest human-made rotor in history. It can spin a dazzling 100,000 times faster than a high-speed dentist drill.
Called an “optically levitated nanodumbbell” in their abstract, one of the lead researchers, Tongcang Li of Indiana’s Purdue University, explained a bit more. “This study has many applications, including material science. We can study the extreme conditions different materials can survive in.”…”
