The fastest man-made object

30 Aug 2013

At ... St Andrew's University, a stone's throw from Trevor, have created the world's fastest spinning man-made object, a microscopic sphere achieving speeds of 600 million revolutions in a minute.

The idea behind the experiment was to discover what might happen to larger objects containing many times more than a million atoms. Essentially, the particle behaved like a small gyroscope, stabilising its motion around the axis of rotation. (so what does this tell us about the axis of the Earth?)

The same story is at ... where we learn they used laser light in a vacuum and the rotation rate reached 600 million revolutions per minute - before breaking apart.
