Scientists develop the fastest spinning object


Scientists have developed the fastest man-made rotor in the world.

The significant development which they believe will help them study quantum mechanics. At more than 60 billion revolutions per minute, this machine is more than 100,000 times faster than a high-speed dental drill.
According to Tongcang Li, an assistant professor at Purdue University , this study has many applications, including material science. We can study the extreme conditions different materials can survive in.
The team synthesised a tiny dumbbell from silica and levitated it in high vacuum using a laser. The laser can work in a straight line or in a circle – when it is linear, the dumbbell vibrates, and when it is circular, the dumbbell spins. A spinning dumbbell functions as a rotor, and a vibrating dumbbell functions like an instrument for measuring tiny forces and torques, known as a torsion balance.
These devices were used to discover things like the gravitational constant and density of Earth, but Li hopes that as they become more advanced, they will be able to study things like quantum mechanics and the properties of vacuum
