Fluid Dynamics

7 October 2014

Tim Cullen is turning his attention to fluid dynamics but not sure what the end result will be – go to http://malagabay.wordpress.com/2014/10/03/couette-flow-1-viscosity/ … which may have repercussions on a lot of things we take for granted. He says there is no settled science involved because of natural complexities recognised by physicists, as such, and the use of approximations and exceptions and various controversies that have developed over the years. A good science subject then.

In other words, viscosity of some fluids may depend on features not in the mainstream models. For example, a magneto rheological fluid becomes thicker when subject to a magnetic field, almost to the point of becoming like a solid. Some people have even claimed amorphous solids, produced from liquids, such as glass and various polymers, are actually liquids. I thought this was interesting as flint (found within chalk deposits) is formed from a viscuous liquid – a jelly like substance that on occasion wrapped itself around marine creatures such as sponges and preserved them as fossils. The origin of flint is a geological mystery – although mainstream might say otherwise. Flint is like glass – and was used like glass on some occasions, to cut things and to clean animal hides or scrape flesh from bones etc. It splits apart and was used to make arrows and barbs.

Louis Hissink, in the comments, invokes Pollock's observations on water and electrical fields – but does flint have an origin in a massive electro-magnetic event. Was it formed at the K/T boundary?
