This finding impliеd that, contrary to Aristotеlian idеas, changеs did occur in thе hеavеns.

Night Vision Optics

Night vision devices (NVD’s) have advanced considerably in recent years and this sophisticated technology is now easily available for anybody interested in outdoor pursuits such as camping, fishing, hunting, astronomy or sailing. Night vision devices work by capturing existing ambient light through the front lens. This light, which is made up of photons goes into a photocathode tube that transforms the photons into electrons. The electrons are then thrown against a phosphorus screen that changes the amplified electrons back into visible light which can be seen through the eyepiece. This image will appear as a clear, green-hued re-creation of the originally observed scene
