Philosophy is written in that great book which
ever lies before our eyes — I mean the universe
— but we cannot understand it if we do not first
learn the language and grasp the symbols,
in which it is written.

Two interesting effect are visible on this photo. If sky stars don't have big trails, reflections of stars have pretty much visible "star roads". Actually every star reflection has its own "star path" like Moon reflection has moonpath. When stars more close to horizon than "star path" of reflection is longer. Reflection stars near horizon also looks brighter because of near horizon light from starts more parallel to water surface and has bigger reflectivity.
