The fastest man-made object

30 Aug 2013

At www.bbc.co.uk/news/uk-scotland-edinburgh-east-fife-23861397 ... 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 http://phys.org/print296905468.html ... where we learn they used laser light in a vacuum and the rotation rate reached 600 million revolutions per minute - before breaking apart.
