| Tóm tắt: | This particular armillary sphere has, I expect, many fascinating historical
stories to tell, but there is a specific reason I framed the picture. Once upon
a time, astronomers speculated about the causes and mechanisms of the
motions of the planets and stars, and their ontology of crystalline spheres
was a central feature of astronomical theory for hundreds of years. But
crystalline spheres are not the sorts of things one can observe, at least not
with the naked eye from the surface of the Earth. Even if it had turned out
that they exist, it is doubtful one would have been able to devise an
instrument to detect them before the days of satellites and space shuttles.
Much of the energy of the sciences is consumed in the attempt to work out
and describe things that are inaccessible to the unaided senses, whether in
practice or in principle. My armillary sphere, with its glorious and complicated
mess of interwoven circles, is a reminder of past testaments to that
obsession. |
