Telescope
A telescope is an optical instrument using lenses, curved mirrors, or a combination of both to observe distant objects, or various devices used to observe distant objects by their emission, absorption, or reflection of electromagnetic radiation.[1] The first known practical telescopes were refracting telescopes invented in the Netherlands at the beginning of the 17th century, by using glass lenses. They were used for both terrestrial applications and astronomy. The reflecting telescope, which uses mirrors to collect and focus light, was invented within a few decades of the first refracting telescope. In the 20th century, many new types of telescopes were invented, including radio telescopes in the 1930s and infrared telescopes in the 1960s [...More Info...]       [...Related Items...] |

Inventor An inventor is a person who creates or discovers a new method, form, device or other useful means that becomes known as an invention. The word inventor comes from the Latin verb invenire, invent-, to find.[1][2] The system of patents was established to encourage inventors by granting limited-term, limited monopoly on inventions determined to be sufficiently novel, non-obvious, and useful. Although inventing is closely associated with science and engineering, inventors are not necessarily engineers nor scientists.[3] |
