Coulomb \Cou`lomb"\ (k??`l?n"), n. [From Coulomb, a French physicist and electrican.] (Physics) The standard unit of quantity in electrical measurements. It is the quantity of electricity conveyed in one second by the current produced by an electro-motive force of one volt acting in a circuit having a resistance of one ohm, or the quantity transferred by one amp[`e]re in one second. Formerly called weber.
Douglas Harper's Etymology Dictionary
1881, named for French chemist Charles-Augustin de Coulomb (1736-1806), who devised a method of measuring electrical quantity. It is the quantity of electricity conveyed in 1 second by a current of 1 ampere. The name is a French form of Columbus.
n. 1 In the International System of Units, the derived unit of electric charge; the amount of electric charge carried by a current of 1 ampere flowing for 1 second. Symbol: C 2 (rfv-sense) Jewelry: pendant. From the homophone for Coulomb in Russian, кулон.
n. a unit of electrical charge equal to the amount of charge transferred by a current of 1 ampere in 1 second [syn: C, ampere-second]
French physicist famous for his discoveries in the field of electricity and magnetism; formulated Coulomb's Law (1736-1806) [syn: Charles Augustin de Coulomb]
1 C = 1 A ⋅ 1 s
1 C = 1 F ⋅ 1 V

Coulomb is a lunar impact crater that lies behind the northwestern limb, on the far side of the Moon. It is located to the west-southwest of the large crater Poczobutt, and northeast of Sarton.
The rim of this crater is mildly eroded, but still retains a well-defined edge and displays some old terracing on the wide inner walls. The exterior of the crater also retains something of an outer rampart, extending for about a third of crater diameter. The satellite crater Coulomb V lies just beyond the west-northwest limb, while on the opposite side Coulomb J lies a short distance from the outer rim, forming a nearly symmetric pattern. The inner walls of the crater have only a few small impacts along the sides, with one near each of the aforementioned satellite craters.
Within the sloping inner walls, the crater floor is remarkably level and nearly featureless, at least in comparison to the more rugged terrain that surrounds the crater. Only a few tiny craterlets mark this interior plain, and a small crater near the south-southeast inner wall.
Coulomb lies within the Coulomb-Sarton Basin, a 530 km wide impact crater of Pre-Nectarian age.

There are no grounds at the moment for postulating that the counterparts of electrical charge, coulomb attraction, and hence molecular adhesion were anything like the quantities we know.
My ability to do even that falls off with distance, roughly as the Coulomb force.
The latter contains Nobel and Schoene elutriators, together with viscosimeters of the flow and the Coulomb and Clark electrical types, sieves, voluminometers, colorimeters, vernier shrinkage gauges, micrometers, microscopes, and the necessary balances.

Using terabytes of qubit quantum data and applying relativistic Coulomb field transforms to these mind-consciousness holographic wavefunctions, it was quickly discovered that human consciousness could be quantum-teleported to points in space-time where entangled-pair wavefronts already existed.
Kyle effects fall off roughly as the coulomb force, so the farther away I am from you, the weaker my interaction with the two of you.
