Usage examples of differential.

Springs, alembics, coils of copper tubing, buckled sheets of metal, gear systems both rack-and-pinion and epicyclic, pendulums, levers, cams, cranks, differentials, bearings, pulleys, assorted tools, and stone jars containing alkahest and corrosive substances crowded every horizontal surface.

Once there is established the differential between the pure, civilized European and the corrupt, barbarous Other, there is possible not only a civilizing process from disease to health, but also ineluctably the reverse process, from health to disease.

He had a guiding principle: nature seemed to like equations stated in covariant differential forms.

His blood chemistry and differential leucocyte count remained normal, and a series of nerve conduction studies indicated that his peripheral nerves were functioning properly.

He improved the differential calculus, solved the isoperimetrical problem and discovered the properties of the logarithmic spiral.

Stop having children until ontogenesis can be described by a set of differential equations?

Edwards had designed the special instrumentation for the Barracuda and the Bluefin that monitored the thermal variations in the water surrounding the submarine, giving the skipper a constant readout of temperature differentials.

The hydrothermal instrumentation in the two blisters on the sail keep us informed of the temperature differentials between the currents, and by sailing the Barracuda directly in the interface zone we are effectively shielded from detection.

I kept the Barracuda directly in the interface between two temperature differentials.

The ringing sets up something similar to a mental moire fringe interference pattern from which an experienced man can read the time differential with almost micrometer accuracy.

When a pilot returns from the manifold years older or younger than his lover, as Soli recently had, the differential aging-we call it crueltime-can destroy them.

I always thought of things like the subjunctive case and differential calculus and chemical symbols as totally useless.

The sunlight sets up a temperature differential - tiny, but enough to get superfluid helium pumping up through the roots.

If the differential and integral calculus or transfinite arithmetic had been invented in Greece in the fifth century B.

It is merely because a stepping-stone, here and there, is heedlessly left unsupplied in our road to the Differential Calculus, that this latter is not altogether as simple a thing as a sonnet by Mr.
