These rhombs have certain angles, and the three which form the pyramidal base of a single cell on one side of the comb, enter into the composition of the bases of three adjoining cells on the opposite side.
41421 (or at some lesser distance), from the centres of the six surrounding spheres in the same layer; and at the same distance from the centres of the adjoining spheres in the other and parallel layer; then, if planes of intersection between the several spheres in both layers be formed, there will result a double layer of hexagonal prisms united together by pyramidal bases formed of three rhombs; and the rhombs and the sides of the hexagonal prisms will have every angle identically the same with the best measurements which have been made of the cells of the hive-bee.
In ordinary combs it has appeared to me that the bees do not always succeed in working at exactly the same rate from the opposite sides; for I have noticed half-completed rhombs at the base of a just-commenced cell, which were slightly concave on one side, where I suppose that the bees had excavated too quickly, and convex on the opposed side, where the bees had worked less quickly.
If they would, for example, praise the beauty of a woman, or any other animal, they describe it by rhombs
, circles, parallelograms, ellipses, and other geometrical terms, or by words of art drawn from music, needless here to repeat.
See, though from far, His thousands, in what martial equipage They issue forth, steel bows and shafts their arms, Of equal dread in flight or in pursuit-- All horsemen, in which fight they most excel; See how in warlike muster they appear, In rhombs
, and wedges, and half-moons, and wings.
Which else to several Sphears thou must ascribe, Mov'd contrarie with thwart obliquities, Or save the Sun his labour, and that swift Nocturnal and Diurnal rhomb
suppos'd, Invisible else above all Starrs, the Wheele Of Day and Night; which needs not thy beleefe, If Earth industrious of her self fetch Day Travelling East, and with her part averse From the Suns beam meet Night, her other part Still luminous by his ray.
The ordering for dolomite rhombs
was found from the intensity ratio of two other dolomite peaks i.
In their later work, they describe the effect of dislocations on etch mark development on amethyst rhombs
Joshi et al.
The first is the collection of triangles with angles that are integer multiples of [pi]/n; the second is the set of rhombs
with the same angles.
This method uses as prototiles the set of rhombs
with angles that are integer multiples of [pi]/n, and includes various special cases that have already been constructed by hand for low values of n.
