Viscosity Quotes (3 quotes)

Big whorls have little whorls
Which feed on their velocity
And little whorls have lesser whorls,
And so on to viscosity.
[Concerning atmospheric turbulence.]
Weather Prediction by Numerical Process (1922), 66. Quoted in Benoit Mandelbrot, The Fractal Geometry of Nature (1977, 1983), 402.

Let us ... consider the ovum [egg] as a physical system. Its potentialities are prodigious and one's first impulse is to expect that such vast potentialities would find expression in complexity of structure. But what do we find? The substance is clouded with particles, but these can be centrifuged away leaving it optically structureless but still capable of development.... On the surface of the egg there is a fine membrane, below it fluid of high viscosity, next fluid of relatively low viscosity, and within this the nucleus, which in the resting stage is simply a bag of fluid enclosed in a delicate membrane.... The egg's simplicity is not that of a machine or a crystal, but that of a nebula. Gathered into it are units relatively simple but capable by their combinations of forming a vast number of dynamical systems...

Memory is to mind as viscosity is to protoplasm it gives a kind of tenacity to thought—a kind of pied terre from which it can, and without it could not, advance.
Samuel Butler, Henry Festing Jones (ed.), The Note-Books of Samuel Butler (1917), 58.

Carl Sagan Thumbnail In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion. (1987) -- Carl Sagan
