The operation of the machine is as follows: Let us suppose that one of the studs on the back plate is positively electrified and one at the opposite end of a diameter is negatively electrified, and that at that moment two corresponding studs on the front plate passing opposite to these back studs are momentarily connected together by the neutralizing wire belonging to the front plate.
Qui in vita sua multo labore circumferentiae circuli proximam rationem ad diametrum invenit sequentem quando diameter est I turn circuli circumferentia plus est quam 100000000000000000000000000000000000 et minus 314159265358979323846264338327950289 100000000000000000000000000000000000..
This first essay (Exetasis quadraturae circuli, Leiden, 1651) was quickly succeeded by his Theoremata de quadratura hyperboles, ellipsis, et circuli; while, in a treatise entitled De circuli magnitudine inventa, he made, three years later, the closest approximation so far obtained to the ratio of the circumference to the diameter of a circle.
A diameter is a line through the centre and terminated by the curve: it bisects all chords parallel to the tangents at its extremities; the diameter parallel to these chords is its conjugate diameter.
In diameter are sufficient for this purpose, but in the tropics, where the transparency is much greater, disks 3 ft.
They have shown that columns of water of very small diameter can so resist tensile strain that they can be lifted bodily instead of flowing along the channel, They suggest that the forces causing the movement are complex, and draw particular attention to the pull upwards in consequence of disturbances in the leaves.
In diameter for the knights of the Round Table, who preceded the knights of the Garter, had been built in 1344 (Chron.
In diameter contracted to an orifice i g inch in diameter, the orifice being nicked by a pair of scissors into a V-shape.
In size they vary between wide limits, from minute sparkling points encrusting rock surfaces and often so thickly clustered together as to produce a drusy effect, to large single crystals measuring a yard in length and diameter and weighing half a ton.
A spur pinion D, gearing with both wheels, is carried loosely upon an eccentric E forming part of the central pin, so that when this latter is turned by the hand-wheel F and chain G the axis of the pinion describes a circle the diameter of which equals the throw of the eccentric, and a small relative motion of the two sheaves takes place, depending on the number of the teeth of the annular wheels.
