Froth

Definition and stakes

Portrait of Robert Hooke Robert Hooke,  Micrographia

“ For, first, if you take any ting’d liquor whatsoever, especially if it be pretty deeply ting’d, and by any means work it into a froth, the congeries of that froth shall seem an opacous body, and appear of the same colour, but much whiter than that of the liquor out of which it is made. For the abundance of reflections of the Rays against those surfaces of the bubbles of which the froth consists, does so often rebound the Rays backwards, that little or no light can pass through, and consequently the froth appears opacous. ”

Portrait of F. Max Müller F. Max Müller,  Lectures on the Science of Language

“ We receive the impression of the falling of a large mass of water, descending always from the same height and with the same difficulty. The scattering of the drops of water, the formation of froth, the sound of the fall by the roaring and by the froth, are constantly produced by the same causes, and, consequently, are always the same. ”
