Otto C. Winzen
Otto C. Winzen (1917–1979) was a German-American aeronautics engineer who made significant advances in the materials and construction of high-altitude balloons after World War II. Winzen emigrated to the United States in 1937 and spent time during the war in internment camps. He studied aeronautical engineering at the University of Detroit. After World War II, Winzen became involved in high-altitude balloon research, working with Jean Piccard. In 1949 he started his own company with his wife Vera Simons, called Winzen Research, Inc. He created a number of plastic balloons, in particular of polyethylene, which he sold to the United States Army and Navy including the Skyhook balloon, and the Air Force's Project Manhigh. In 1972 he developed the Winzen Research Balloon, which achieved the record for the highest unmanned balloon flight, setting a record altitude of 51,816 m over Chico, California Chico ( ; Spanish language, Spanish for "little") is the most populous city ...

Aeronautics Engineer
Aerospace engineering is the primary field of engineering concerned with the development of aircraft and spacecraft. It has two major and overlapping branches: aeronautical engineering and astronautical engineering. Avionics engineering is similar, but deals with the electronics side of aerospace engineering. "Aeronautical engineering" was the original term for the field. As flight technology advanced to include vehicles operating in outer space, the broader term "aerospace engineering" has come into use. Aerospace engineering, particularly the astronautics branch, is often colloquially referred to as "rocket science". Overview Flight vehicles are subjected to demanding conditions such as those caused by changes in atmospheric pressure and temperature, with structural loads applied upon vehicle components. Consequently, they are usually the products of various technological and engineering disciplines including aerodynamics, air propulsion, avionics, materials science, stru ...

Project Manhigh
Project Manhigh was a pre-Space Age military project that took men in Balloon (aircraft), balloons to the middle layers of the stratosphere, funded as an aero-medical research program, though seen by its designers as a stepping stone to space. It was conducted by the United States Air Force between 1955 and 1958. History The project History of the United States (1945–1964), started in December 1955 to study the effects of cosmic rays on humans. Three balloon flights to the stratosphere were made during the program: * Manhigh I to , by Captain (land and air), Captain Joseph W. Kittinger on June 2, 1957. The balloon was launched from South St. Paul Airport and the flight was cut short due to one of the capsule's valves being installed backwards which vented the oxygen supply outside, but not before reaching a record altitude of 96,784 feet. * Manhigh II to , by Major (rank), Major David G. Simons on August 19–20, 1957, launched from Portsmouth Mine in Crosby, Minnesota, for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Emigrants From Nazi Germany To The United States
Emigration is the act of leaving a resident country or place of residence with the intent to settle elsewhere (to permanently leave a country). Conversely, immigration describes the movement of people into one country from another (to permanently move to a country). A migrant ''emigrates'' from their old country, and ''immigrates'' to their new country. Thus, both emigration and immigration describe migration, but from different countries' perspectives. Demographers examine push and pull factors for people to be pushed out of one place and attracted to another. There can be a desire to escape negative circumstances such as shortages of land or jobs, or unfair treatment. People can be pulled to the opportunities available elsewhere. Fleeing from oppressive conditions, being a refugee and seeking asylum to get refugee status in a foreign country, may lead to permanent emigration. Forced displacement refers to groups that are forced to abandon their native country, such as by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bonnier Corporation
Bonnier LLC (formerly Bonnier Corporation) is an American "outdoor adventure" company that originally operated numerous U.S.-based media brands but struggled in the magazine publishing industry, leading to the decline or closure of several well-known titles. Formed in 2007 after Bonnier Group's acquisition of publishing assets from Time, today it operates events within the vertical of outdoor recreation. History The company was formed in March 2007 as the U.S. subsidiary of Bonnier Group, after it acquired the 18 magazines of the Time Warner divisions Time4 Media (owner of publications such as '' Transworld Skateboarding'') and The Parenting Group (owner of publications such as ''Parenting'') for $200 million, and combined them with its 50% stake in World Publications.

Popular Science
Popular science (also called pop-science or popsci) is an interpretation of science intended for a general audience. While science journalism focuses on recent scientific developments, popular science is more broad ranging. It may be written by professional science journalists or by scientists themselves. It is presented in many forms, including books, film and television documentaries, magazine articles, and web pages. History Before the modern specialization and professionalization of science, there was often little distinction between "science" and "popular science", and works intended to share scientific knowledge with a general reader existed as far back as Greek and Roman antiquity. Without these popular works, much of the scientific knowledge of the era might have been lost. For example, none of the original works of the Greek astronomer Eudoxus (4th century BC) have survived, but his contributions were largely preserved due to the didactic poem '' Phenomena'' writte ...

Skyhook Balloon
Skyhook balloons were high-altitude balloons developed by Otto C. Winzen and General Mills, Inc. They were used by the United States Navy Office of Naval Research (ONR) in the late 1940s and 1950s for atmospheric research, especially for constant-level meteorological observations at very high altitudes. Instruments like the Cherenkov detector were first used on Skyhook balloons. Project Skyhook In the late 1940s, Project Skyhook was conceived of as a means by which plastic balloons could be used to transmit or send instruments into the stratosphere to conduct research. This project carried forward work from an earlier project, Helios, that General Mills and Jean Piccard initiated to use arrays of giant plastic balloons to carry humans aloft. Balloons, long used for collecting meteorological data, now offered the opportunity of collecting highly specialized information and photographs. The first Skyhook balloon was launched on September 25, 1947. The balloon was developed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
High-altitude Balloons
Altitude is a distance measurement, usually in the vertical or "up" direction, between a reference datum and a point or object. The exact definition and reference datum varies according to the context (e.g., aviation, geometry, geographical survey, sport, or atmospheric pressure). Although the term ''altitude'' is commonly used to mean the height above sea level of a location, in geography the term elevation is often preferred for this usage. In aviation, altitude is typically measured relative to mean sea level or above ground level to ensure safe navigation and flight operations. In geometry and geographical surveys, altitude helps create accurate topographic maps and understand the terrain's elevation. For high-altitude trekking and sports, knowing and adapting to altitude is vital for performance and safety. Higher altitudes mean reduced oxygen levels, which can lead to altitude sickness if proper acclimatization measures are not taken. Vertical distance measurements in t ...

Polyethylene
Polyethylene or polythene (abbreviated PE; IUPAC name polyethene or poly(methylene)) is the most commonly produced plastic. It is a polymer, primarily used for packaging (plastic bags, plastic films, geomembranes and containers including bottles, cups, jars, etc.). , over 100 million tonnes of polyethylene resins are being produced annually, accounting for 34% of the total plastics market. Many kinds of polyethylene are known, with most having the chemical formula (C2H4)''n''. PE is usually a mixture of similar polymers of ethylene, with various values of ''n''. It can be ''low-density'' or ''high-density'' and many variations thereof. Its properties can be modified further by crosslinking or copolymerization. All forms are nontoxic as well as chemically resilient, contributing to polyethylene's popularity as a multi-use plastic. However, polyethylene's chemical resilience also makes it a long-lived and decomposition-resistant pollutant when disposed of improperly. Being a h ...
