The Porter Garden Telescope
The Porter Garden Telescope was an innovative ornamental telescope for the garden designed by Russell W. Porter and commercialized by Jones & Lamson Machine Company at the beginning of the 1920s in the United States. Oriented to users with high purchasing power, and constructed in statuary bronze, it could be left permanently outdoors like sculptures and sundials, keeping the delicate optics in a case. It was embellished with floral ornament, with a style close to the art nouveau. In its base were the names of celebrated astronomers: Galileo, Kepler, and Newton. The part called the bowl bore the commercial logo "The Porter Garden Telescope", the name and address of the manufacturer, the serial number of manufacture, and the number and date of the patent. Technical characteristics * Material of construction: Bronze. * Reflecting telescope, Newtonian type. * Without tube that wrap the optics. * Mount: Combination of altazimuth (terrestrial use) and equatorial type horse ...

Longwood Gardens
Longwood Gardens is a botanical garden that consists of over 1,077 acres (436 hectares; 4.36 km2) of gardens, woodlands, and meadows in Kennett Square, Pennsylvania, United States in the Brandywine Creek Valley. It is one of the premier horticultural display gardens in the United States and is open to visitors year-round to enjoy native and exotic plants and horticulture (both indoor and outdoor), events and performances, seasonal and themed attractions, as well as educational lectures, courses, and workshops. History Longwood Gardens has a long varied history. For thousands of years, the native Lenni Lenape tribe fished its streams, hunted its forests, and planted its fields. Evidence of the tribe's existence is found in quartz spear points that have been discovered on and around the property and can be found on display in the Peirce-du Pont House on the Longwood Gardens property. In 1700, a Quaker farmer named George Peirce purchased 402 acres of this English-claimed l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scientific American
''Scientific American'', informally abbreviated ''SciAm'' or sometimes ''SA'', is an American popular science magazine. Many famous scientists, including Albert Einstein and Nikola Tesla, have contributed articles to it. In print since 1845, it is the oldest continuously published magazine in the United States. ''Scientific American'' is owned by Springer Nature, which in turn is a subsidiary of Holtzbrinck Publishing Group. History ''Scientific American'' was founded by inventor and publisher Rufus Porter (painter), Rufus Porter in 1845 as a four-page weekly newspaper. The first issue of the large format newspaper was released August 28, 1845. Throughout its early years, much emphasis was placed on reports of what was going on at the United States Patent and Trademark Office, U.S. Patent Office. It also reported on a broad range of inventions including perpetual motion machines, an 1860 device for buoying vessels by Abraham Lincoln, and the universal joint which now can be found ...

1925 Santa Barbara Earthquake
The 1925 Santa Barbara earthquake hit the area of Santa Barbara, California on June 29, with a moment magnitude between 6.5 and 6.8 and a maximum Mercalli Intensity of IX (''Violent''). It resulted in 13 deaths and destroyed the historic center of the city, with damage estimated at $8 million (about $111 million in 2017). Earthquake Although no foreshocks were reported felt before the mainshock, a pressure gauge recording card at the local waterworks showed disturbances beginning at 3:27 a.m., which were likely caused by foreshocks. At 6:44 a.m. the mainshock occurred which lasted 19 seconds. The epicenter of the earthquake was located in the sea off the coast of Santa Barbara, in the Santa Barbara Channel. The fault on which it occurred appears to have been an extension of the Mesa fault or the Santa Ynez system. The earthquake was felt from Paso Robles (San Luis Obispo County) to the north to Santa Ana (Orange County) to the south and to Mojave (Kern Cou ...

Hale Telescope
The Hale Telescope is a , 3.3 reflecting telescope at the Palomar Observatory in San Diego County, California, US, named after astronomer George Ellery Hale. With funding from the Rockefeller Foundation in 1928, he orchestrated the planning, design, and construction of the observatory, but with the project ending up taking 20 years he did not live to see its commissioning. The Hale was groundbreaking for its time, with double the diameter of the second-largest telescope, and pioneered many new technologies in telescope mount design and in the design and fabrication of its large aluminum coated "honeycomb" low thermal expansion Pyrex mirror. It was completed in 1949 and is still in active use. The Hale Telescope represented the technological limit in building large optical telescopes for over 30 years. It was the largest telescope in the world from its construction in 1949 until the Soviet BTA-6 was built in 1976, and the second largest until the construction of the Keck Observ ...

Art Deco
Art Deco, short for the French ''Arts Décoratifs'', and sometimes just called Deco, is a style of visual arts, architecture, and product design, that first appeared in France in the 1910s (just before World War I), and flourished in the United States and Europe during the 1920s and 1930s. Through styling and design of the exterior and interior of anything from large structures to small objects, including how people look (clothing, fashion and jewelry), Art Deco has influenced bridges, buildings (from skyscrapers to cinemas), ships, ocean liners, trains, cars, trucks, buses, furniture, and everyday objects like radios and vacuum cleaners. It got its name after the 1925 Exposition internationale des arts décoratifs et industriels modernes (International Exhibition of Modern Decorative and Industrial Arts) held in Paris. Art Deco combined modern styles with fine craftsmanship and rich materials. During its heyday, it represented luxury, glamour, exuberance, and faith in socia ...

Ford Model T
The Ford Model T is an automobile that was produced by Ford Motor Company from October 1, 1908, to May 26, 1927. It is generally regarded as the first affordable automobile, which made car travel available to middle-class Americans. The relatively low price was partly the result of Ford's efficient fabrication, including assembly line production instead of individual handcrafting. It was mainly designed by an American ( Childe Harold Wills) and two Hungarian engineers ( Joseph A. Galamb, Eugene Farkas). The Model T was colloquially known as the "Tin Lizzie", "Leaping Lena" or "flivver". The Ford Model T was named the most influential car of the 20th century in the 1999 Car of the Century competition, ahead of the BMC Mini, Citroën DS, and Volkswagen Beetle. Ford's Model T was successful not only because it provided inexpensive transportation on a massive scale, but also because the car signified innovation for the rising middle class and became a powerful symbol of the U ...

John Brashear
John Alfred Brashear (November 24, 1840 – April 8, 1920) was an American astronomer and instrument builder. Life and work Brashear was born in Brownsville, Pennsylvania, a town 35 miles (56 km) south of Pittsburgh along the Monongahela River. His father, Basil Brown Brashear, was a saddler, and his mother, Julia Smith Brashear, was a school teacher. He was the oldest of seven children. As a boy, John Brashear was heavily influenced by his maternal grandfather, Nathanial Smith, a clock repairer. When he was nine, his grandfather took him to view through the telescope of 'Squire' Joseph P. Wampler, who set up his traveling telescope in Brownsville. That influential view of the moon and the planet Saturn stayed with Brashear for the rest of his life. After receiving a common school education until age 15, he became an apprentice to a machinist and had mastered his trade at age 20. Beginning in 1861 Brashear worked as a millwright in a rolling steel mill in Pittsburgh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Refracting Telescope
A refracting telescope (also called a refractor) is a type of optical telescope that uses a lens (optics), lens as its objective (optics), objective to form an image (also referred to a dioptrics, dioptric telescope). The refracting telescope design was originally used in spyglasses and astronomy, astronomical telescopes but is also used for long-focus lens, long-focus camera lenses. Although large refracting telescopes were very popular in the second half of the 19th century, for most research purposes, the refracting telescope has been superseded by the reflecting telescope, which allows larger apertures. A refractor's magnification is calculated by dividing the focal length of the objective lens by that of the eyepiece. Refracting telescopes typically have a lens at the front, then a optical train, long tube, then an eyepiece or instrumentation at the rear, where the telescope view comes to focus. Originally, telescopes had an objective of one element, but a century later, tw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
