Description of a cheap and portable Instrument for enabling Young People to acquire a knowledge of the Stars, or determine their situation in the Heavens. By S. Lee, Esq. [◊]
THERE is no science, the study of which tends so much to enlarge the mind as Astronomy. It opens to our view the grandest examples of Almighty power, wisdom, and beneficence—the [p372] contemplation of which fills the soul with reverence and affection for the great Author of nature, and banishes all narrow and superstitious notions respecting him.
The cultivation of this science, therefore, cannot be too strongly recommended to the attention of young people. The eager curiosity and avidity for discovery which so peculiarly distinguish that period of life, when the reasoning faculties begin to develope, is peculiarly fitted for its reception—and, accordingly, amongst the better-educated classes of society, the elements of this science are generally considered as a necessary branch of instruction—though commonly limited to a mere dogmatic explanation of the Copernican system, and the use of the globes.
But this superficial mode of instruction, though sufficient to enable any one to understand the real motions of our planetary system, and explain the apparent motions which must result from them, is hardly sufficient to satisfy inquisitive reasoning minds, since it leaves them ignorant of the means by which the distances, magnitudes, and orbits of the planets and comets were first discovered; and how, if lost, a knowledge of them might be recovered from observations alone.
The most pleasing methods of instruction will generally be found the most efficient. It is impossible for any one who has had the least experience in teaching not to have perceived, that one practical application of science makes a deeper and more lasting impression on the mind of a learner than a thousand theoretic propositions.
An accurate knowledge of the fixed stars is the first step to practical astronomy; it is, in fact, the alphabet of the science. By the rising, southing, and setting of these bodies, astronomers are enabled correctly to measure time; and from their apparent altitudes, to determine the latitude of places on the surface of the globe, whilst the permanent situations which they maintain with respect to one another, furnish them with so many marks by which to trace the course of the sun, moon, and planets through the heavens. Such were the data which enabled Copernicus and Newton to unravel the seeming irregularity of their apparent paths, and explain the beautiful simplicity of their real motions.
