ponderable

From Lorentz stems the conception of the electron; his view that his minute, electrically charged particle plays a rôle during electromagnetic phenomena in ponderable matter made it possible to apply the molecular theory to the theory of electricity, and to explain the behaviour of light waves passing through moving, transparent bodies.

We will return to the propagation of light in ponderable matter.

Hendrik A. Lorentz - Nobel Lecture 1967

In the older theory of undulation, which considered the ether as an elastic medium, there was already talk of tiny particles contained in ponderable substances which could be set in motion by light vibrations.

Hendrik A. Lorentz - Nobel Lecture 1967

At the same time, a start was made on a general theory which ascribed all electromagnetic processes taking place in ponderable substances to electrons.

Hendrik A. Lorentz - Nobel Lecture 1967

One could never get a clear picture of the interior forces governing the ether, nor of the forces acting between the ether and the "ponderable" matter.

But just at the close of the century the confidence in the status of the imponderables was rudely shaken in the minds of philosophers by the revival of the old idea of Fra Paolo and Bacon and Boyle, that heat, at any rate, is not a material fluid, but merely a mode of motion or vibration among the particles of "ponderable" matter.

Without exception, the authoritative physicists of our time accept this plenum as a verity, and reason about it with something of the same confidence they manifest in speaking of "ponderable" matter or of, energy.

The few leaders then saw clearly enough that if one form of energy is in reality merely an undulation or vibration among the particles of "ponderable" matter or of ether, all other manifestations of energy must be of the same nature.

From the time he took up his headquarters on the hill at Cassel, he became “a desk man”; it was no longer his function to execute orders; thenceforth he had the far more trying duty of issuing orders ” a truly awful responsibility and one which demands much solitude, much soul-searching as well as map-pondering and other weighing of the ponderable which is so easily off-set by the imponderable, the unguessable.

Foch the Man Laughlin, Clara E 1918

There is a ponderable and somewhat strange quotation of Jesus in the Christian Gospel of St. Matthew.
