The Large Binocular Telescope had its first light with a single primary mirror on 12 October 2005, which was a view of NGC 891. [5] [6] The second primary mirror was installed in January 2006 and became fully operational in ...

In all of these, the same 'thing' is known, but in different degrees of clarity and profundity.

The early writers discussed here treated vision more as a geometrical than as a physical, physiological, or psychological problem. The first known author of a treatise on geometrical optics was the geometer Euclid (c. 325 BC–265 BC). Euclid began his study of optics as he began his study of geometry, with a set of self-evident axioms.
This is a list of sources of light, the visible part of the electromagnetic spectrum.Light sources produce photons from another energy source, such as heat, chemical reactions, or conversion of mass or a different frequency of electromagnetic energy, and include light bulbs and stars like the Sun. Reflectors (such as the moon, cat's eyes, and mirrors) do not actually produce the light that ...
