- n. A Cassinian: a misapplication of the word originating in Germany.
- n. The locus of the point in which the straight through the center and the projection of a point of a circle on a fixed tangent are cut by the perpendicular from this point to the diameter from the contact point.
'lemniscate', a particular modification of the so-called Cassinian curves. 2 1
Her gaze was caught on the glowing wand and lemniscate, and she thought of radiation.
A lemniscate, an infinity symbol, glowed above his head.
You mentioned lemniscate periodic systems in one of your chemistry blogs.
The one Ariel did recognize shone bright white in the center of the robot's upper torso, a lemniscate crossed by an arrow at an upward angle: the sign of the Managins.
Some projective-geometrical considerations concerning the lemniscate are to be found in the previously mentioned writings of G. Adams and L. L.cher-Ernst.
You have read, too, in _The Secret Doctrine, _ P.ofessor Crooke's theory, endorsed by H.P. Blavatsky, as to how the chemical elements were deposited by a spiral evolutive force, a creative impulse working outward in the form of a caduceus or lemniscate, or figure '8.'
About the epoch of maximum of sun-spots they are large and nearly circular, having the same character as the curves for the summer months; whilst about the time of sun-spot minimum they are small and lemniscate-shaped, with a striking resemblance to the curves for the winter months.
According to the lemniscate arrangement, we should commence with hydrogen as the head of the first negative group, but as it differs wholly from those placed with it, it is better to take it by itself.
We follow here the grouping according to external forms, and the student should compare it with the groups marked in the lemniscate arrangement shown in Article II (p. 377, properly p. 437, February), reading the group by the disks that fall below each other; thus the first group is H, Cl, Br,
