Information: - A Bachelor of Science (Latin ', B.S., BS, B.Sc., or BSc; or, less commonly, S.B., SB, or Sc.B., from the equivalent Latin ') is an undergraduate academic degree awarded for completed courses that generally last three to five years. - A magic carpet, also called a flying carpet, is a legendary carpet that can be used to transport humans who are on it instantaneously or quickly to their destination. - Stevens Institute of Technology (SIT) is a private, coeducational research university located in Hoboken, New Jersey, United States. The university also has a satellite location in Washington, D.C.. Incorporated in 1870, it is one of the oldest technological universities in the United States, and was the first college in America solely dedicated to mechanical engineering. The campus encompasses Castle Point, the highest point in Hoboken, and several other buildings around the city. - A carpet is a textile floor covering typically consisting of an upper layer of pile attached to a backing. The pile was traditionally made from wool, but, since the 20th century, synthetic fibers such as polypropylene, nylon or polyester are often used, as these fibers are less expensive than wool. The pile usually consists of twisted tufts which are typically heat-treated to maintain their structure. The term "carpet" is often used interchangeably with the term "rug", although the term "carpet" can be applied to a floor covering that covers an entire house, whereas a "rug" is generally no bigger than a single room, and traditionally does not even span from one wall to another, and is typically not even attached as part of the floor. - An autogyro (from Greek + , "self-turning"), also known as gyroplane, gyrocopter, or rotaplane, is a type of rotorcraft that uses an unpowered rotor in autorotation to develop lift, and an engine-powered propeller, similar to that of a fixed-wing aircraft, to provide thrust. While similar to a helicopter rotor in appearance, the autogyro's rotor must have air flowing through the rotor disc to generate rotation. Invented by the Spanish engineer Juan de la Cierva to create an aircraft that could fly safely at slow speeds, the autogyro was first flown on 9 January 1923, at Cuatro Vientos Airfield in Madrid. De la Cierva's aircraft resembled the fixed-wing aircraft of the day, with a front-mounted engine and propeller in a tractor configuration to pull the aircraft through the air. - The Bensen Aircraft Corporation was established by Dr. Igor Bensen at Raleigh-Durham International Airport in North Carolina in 1952 to develop and market a variety of helicopters and autogyros of Bensen's own design. - Modern humans ("Homo sapiens", primarily ssp. "Homo sapiens sapiens") are the only extant members of Hominina tribe (or human tribe), a branch of the tribe Hominini belonging to the family of great apes. They are characterized by erect posture and bipedal locomotion; manual dexterity and increased tool use, compared to other animals; and a general trend toward larger, more complex brains and societies. - The Bensen B - 12 , variously dubbed the Sky - Way or Sky - Mat was an unconventional multirotor developed by Igor Bensen in the United States in the late 1950s . Extremely unorthodox , the design sprang from Bensen 's thinking about the engine redundancy necessary to ensure the safe operation of small , personal rotorcraft operating at low altitudes and slow speeds . The result was a broad aluminum framework supporting an array of ten engines and rotors that Bensen likened to a '' magic carpet '' . The design was later refined to include eight rotors , each driven by two engines for a total of sixteen . Successfully flown in 1961 at altitudes up to 20 ft ( 6 m ) , Bensen felt that the approach had potential for military heavy - lift or agricultural applications , but nothing further came of it . - Igor B. Bensen (April 1, 1917 February 10, 2000) was the founder of the Bensen Aircraft, which produced a successful line of gyrogliders (rotor kites) and autogyros. He was born in Rostov-on-Don, Russia, and eventually reached the United States in 1937. He began studies at age 17 while in Belgium, won a scholarship to study in the USA three years later, and was awarded a Bachelor of Science degree in mechanical engineering from Stevens Institute of Technology in Hoboken, New Jersey in 1940, later becoming a Registered Professional Engineer. - Rostov-on-Don is a port city and the administrative center of Rostov Oblast and the Southern Federal District of Russia. It lies in the southeastern part of the East European Plain on the Don River, from the Sea of Azov. The southwestern suburbs of the city abut the Don River delta.
