Dearest Peeps Of Academia ala Top Notch Mode,
As a sheepie I of course enjoy imbibing liquids ! Imbibing them is my all time favourite past time when it comes to drinking liquids.
Check out these liquids !

A Watery Liquid Of Water

A Come-Hither Wanton Luxuriant Depraved Immoral Choccy Fountain !
The choccy liquid(Heathen Wench !) is known as a Non Newtonian Liquid !!....Of course it is !!..a nomenclaturial label that I use every day !..just rolls off the tongue doesn't it ?
What is a Non Newtonian Liquid ?...What Has Newton got to do with it ?....presumably any other liquid must then be a Newtonian liquid yes ?..are there other terms used to identify liquids using scientists names ?
Ewe see....I really do not know.....and I think I would like to know !
Hugs & shmishes
mwah mwah mwah !!

I Had A Non Newtonian Smoothie Today

I think they are fluids that do not have a single flow rate but can vary depending on temperature etc
-
Cornflour mixed with water is another example: when you keep it moving it behaves like a solid, but if you stop, it behaves like a liquid and goes everywhere!
Wikipedia has a good page on non newtonian liquids http://en.wikipedia.org/wiki/Non-Newtonian_fluid
-
It's a liquid that shows a non-proportional reaction to the forces acting on it - so with the cornflower/water mix, a larger force won't just make it squidge faster.

Gosh...Thanks Hadrian....then this must mean that Newtonian liquids flow at the same rate when hotty or coldy !
ewe are klevur !

Wicked !!..Thanks Kerry !!..so...Non Newtonian can also mean that the liquid can act like a solid !....thanks for the link ...me go lookey soon ! Does that mean that for a moment it IS actually a solid ?

Thanks Ben...this is all really helpful.....any idea what Newton has to do with all of this ?

Newtonian fluid
From Wikipedia, the free encyclopedia
A Newtonian fluid (named after Isaac Newton) is a fluid whose stress versus strain rate curve is linear and passes through the origin. The constant of proportionality is known as the viscosity.

woo !!..Thank ewe Hadrian.....I still not know the Newton connection , except, that it's named after him.

You obviously never saw Newton in the bath. [::)]
-
how about this then.
Newton tried to quantify and predict fluid flow phenomena through his elementary Newtonian physical equations. His contributions to fluid mechanics included his second law: F=m.a, the concept of Newtonian viscosity in which stress and the rate of strain vary linearly, the reciprocity principle: the force applied upon a stationary object by a moving fluid is equal to the change in momentum of the fluid as it deflects around the front of the object, and the relationship between the speed of waves at a liquid surface and their wavelength.
-
...and therefore, a non Newtonian fluid is one to which this does not necessary aply - a greater force to the same mass doesn't result in a proportional increase in acceleration.
So if you handle it softly, it flows, but apply a large force and it locks up like a solid.

Mrs Geezer is a bit like that.
