Merz Telescopes
Georg Merz (26 January 1793 – 12 January 1867) was a Bavarian optician and manufacturer of astronomical telescopes and other optical instruments. Life Merz was born on 26 January 1793 in Bichl, in Bad Tölz-Wolfratshausen, now in Bavaria, Germany. At the age of 15 he went to work in the glassworks recently set up by in the nearby deconsecrated monastery of Benediktbeuern. There he became the assistant of Joseph Fraunhofer. From 1826, when Fraunhofer died, Merz was in charge of the optical division of the business. On the death of von Utzschneider in 1839 Merz, in partnership with Joseph Mahler, bought the firm. After Mahler's death he ran the business in partnership with his sons Ludwig and Sigmund. When Ludwig died in 1858 the name was changed to G. & S. Merz. Georg Merz died in Munich on 12 January 1867. In 1882 the firm passed to Jacob and Matthias Merz, Sigmund's cousins, and in 1884 the Benediktbeuern works was closed. The company moved to Munich, and closed in 1903. ...

Telescope Manufacturers
A telescope is a device used to observe distant objects by their emission, absorption, or reflection of electromagnetic radiation. Originally meaning only an optical instrument using lenses, curved mirrors, or a combination of both to observe distant objects, the word ''telescope'' now refers to a wide range of instruments capable of detecting different regions of the electromagnetic spectrum, and in some cases other types of detectors. The first known practical telescopes were refracting telescopes with glass lenses and were invented in the Netherlands at the beginning of the 17th century. 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. Etymology The word ''telescope'' was coine ...

Optical Engineers
Optics is the branch of physics that studies the behaviour and properties of light, including its interactions with matter and the construction of optical instruments, instruments that use or Photodetector, detect it. Optics usually describes the behaviour of visible light, visible, ultraviolet, and infrared light. Because light is an electromagnetic wave, other forms of electromagnetic radiation such as X-rays, microwaves, and radio waves exhibit similar properties. Most optical phenomena can be accounted for by using the Classical electromagnetism, classical electromagnetic description of light. Complete electromagnetic descriptions of light are, however, often difficult to apply in practice. Practical optics is usually done using simplified models. The most common of these, geometric optics, treats light as a collection of Ray (optics), rays that travel in straight lines and bend when they pass through or reflect from surfaces. Physical optics is a more comprehensive model of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Engineers From Bavaria
Engineers, as practitioners of engineering, are professionals who invent, design, analyze, build and test machines, complex systems, structures, gadgets and materials to fulfill functional objectives and requirements while considering the limitations imposed by practicality, regulation, safety and cost. "Science is knowledge based on our observed facts and tested truths arranged in an orderly system that can be validated and communicated to other people. Engineering is the creative application of scientific principles used to plan, build, direct, guide, manage, or work on systems to maintain and improve our daily lives." The word ''engineer'' (Latin Latin (, or , ) is a classical language belonging to the Italic branch of the Indo-European languages. Latin was originally a dialect spoken in the lower Tiber area (then known as Latium) around present-day Rome, but through the power of the ... ) is derived from the Latin words ("to contrive, devise") and ("cleverness").

Museo Astronomico E Orto Botanico Di Brera
The Brera Observatory ( it, Osservatorio Astronomico di Brera) is an astronomical observatory in the Brera district of Milan, Italy. It was built in the historic Palazzo Brera in 1764 by the Jesuit astronomer Roger Boscovich. Following the suppression of the Jesuits by Clement XIV on 21 July 1773, the palace and the observatory passed to the then rulers of northern Italy, the Austrian Habsburg dynasty. From 1 December 1786, the Austrian Empire adopted “transalpine time”. The astronomers were engaged by Count Giuseppe Di Wilczek, the plenipotentiary governor of Lombardy, to build a meridian line inside Milan Cathedral. It was constructed by Giovanni Angelo Cesaris and Francesco Reggio, with Roger Joseph Boscovich acting as a consultant. Following the independence of Italy in 1861, the observatory has been run by the Italian government. In 1862, the newly installed Italian government improved the observatory's facilities by commissioning a 218mm Merz Equatorial Refracting T ...
