"Look closely and you can see Centauri's binary suns. Here, with no refraction, a small telescope can do as well as the best that your people have made. There is no telling what your large ones could do. Ah, the riddles that could be answered." Odin shrugged. Like almost everyone else, he had often fancied how it would be to land on the moon.
Syenite originally received its name from the celebrated ancient quarries of Syene, in Egypt. It differs from granite in having hornblende as a substitute for mica, and being without quartz. Werner at least considered syenite as a binary compound of feldspar and hornblende, and regarded quartz as merely one of its occasional minerals.
In the first-named star the magnitudes are four and eight, distance 55", p. 144°, colors finely contrasted, pale yellow and red. Much more interesting, however, is 70, a binary whose components have completed a revolution since their discovery by Sir William Herschel, the period being ninety-five years.
Passing eastward, we turn again into Ophiuchus, and find immediately the very interesting double, lambda, whose components are of magnitudes four and six, distance 1", p. 55°. This is a long-period binary, and notwithstanding the closeness of its stars, our four-inch should separate them when the seeing is fine. We shall do better, however, to try with the five-inch.
He is a binary automaton driven by a set of two instructions become someone and overcome resistance. He feels like a nobody and his overriding ambition is to be somebody, even if he has to fake it, or steal it. His only talents, he openly admits, are to fake both personalities and papers. He is a predator and he hunts for congruence, cohesion and meaning. He is in constant search of a family.
This was done in the mineralogical nomenclature proposed by Professor Mohs. “The names framed by him were not composed of two, but of three elements, designating respectively the Species, the Genus, and the Order; thus he has such species as Rhombohedral Lime Haloide, Octohedral Fluor Haloide, Prismatic Hal Baryte.” The binary construction, however, has been found sufficient in botany and zoology, the only sciences in which this general principle has hitherto been successfully adopted in the construction of a nomenclature.
Hardly less beautiful is zeta magnitudes five and six, distance 24", p. 64°. Finest of all is alpha, which exhibits a remarkable color contrast, the larger star being greenish and the smaller blue. The magnitudes are four and five, distance 3", p. 320°. This star is a binary, but the motion is slow.
Their distance in 1886 was 0.78", p. 286°, and they had then been closing rapidly since 1884, when the distance was 1.26". The third star, of magnitude eight, is distant 11", p. 75°. Sigma 2744 consists of two stars, magnitudes six and seven, distance 1.4", p. 1.67°. It is probably a binary.
There are exceptions to this premature end; sometimes the two eggs develop equally well; but such cases are exceptional, so that the Bruchid family would be reduced to about half its dimensions if the binary system were the rule. To the detriment of our peas and to the advantage of the beetle, the eggs are commonly laid one by one and in isolation.
The calculations of the mass and distance and orbital motion of the other star were therefore very difficult, but the final results looked good. The other star and this one formed a binary, the two being of only slightly different mass and rotating about each other at a distance of roughly two million miles.
