Purdue university's scientists create world's fastest spinning man made object

World's fastest spinning man made object

• Scientists create world's fastest spinning man made object.
• The object precisely is not a object but a nano particle which is in dumbbell shaped.
• The nano particle is made up of silica and was levitated by using laser in vacuum. 
• The noted rotation per second (rps) of the nano particle was about 60 billion rps. 
• Scientists behind this invention are Tongcang Li and Jonghoon Ahn. 
• Tongcang Li is assistant professor of physics and astronomy and also serve as assistant professor in computer engineering and electrical engineering in Purdue University. 
• According to Tongcang Li the dumbbell shaped particle was levitated in vacuum with using laser work. 
• The laser used having capability of working in a straight line and in circle helped in finding two motion of the nano particle  
• When the laser work in straight line the nano particle vibrates. 
• When the laser work in circle the dumbbell spins. 
• The spinning dumbbell work as a rotor and the vibrating dumbbell functions like an instrument which can measure tiny forces and torques  
• This kind of instruments can work as an excellent torsion balance.
• Torsion balance device were used for discovering things like gravitational constant ,density of earth. 
• According to Tongcang Li that further advancement can help in to study more typical things like quantum mechanics. 
• Normal people thinks that vacuum is a complete vacant space but physician knows that vacuum a vacant space is a myth ,there are millions of particles which appears for infinitesimal small duration and than disappears . 
• Tongcang Li and his co scientist want to make a torsional balance with this dumbbell nano particle to study vacuum  
• Thus this nano particle motions can help in studying about vacuum friction and gravity which is essential for Modern Physics.
