The TRS-80 Micro Computer System is a desktop microcomputer launched in 1977 and sold by Tandy Corporation through their Radio Shack stores. The name is an abbreviation of Tandy Radio Shack, Z80 [microprocessor]. It is one of the earliest mass-produced and mass-marketed retail home computers.
A wing is a type of fin that produces lift while moving through air or some other fluid. Accordingly, wings have streamlined cross-sections that are subject to aerodynamic forces and act as airfoils. A wing's aerodynamic efficiency is expressed as its lift-to-drag ratio. The lift a wing generates at a given speed and angle of attack can be one to two orders of magnitude greater than the total drag on the wing. A high lift-to-drag ratio requires a significantly smaller thrust to propel the wings through the air at sufficient lift.
The Abenaki people are an indigenous peoples of the Americas located in the Northeastern Woodlands region. Their religious beliefs are part of the Midewiwin tradition, with ceremonies led by medicine keepers, called Medeoulin or Mdawinno.
Invisibility is the state of an object that cannot be seen. An object in this state is said to be invisible. The phenomenon is studied by physics and perceptual psychology.
An ornithopter is an aircraft that flies by flapping its wings. Designers sought to imitate the flapping-wing flight of birds, bats, and insects. Though machines may differ in form, they are usually built on the same scale as flying animals. Larger, crewed ornithopters have also been built and some have been successful. Crewed ornithopters are generally powered either by engines or by the pilot.
A jet pack, rocket belt, rocket pack or flight pack is a device worn as a backpack which uses jets to propel the wearer through the air. The concept has been present in science fiction for almost a century and the first working experimental devices were demonstrated in the 1960s.
Robot locomotion is the collective name for the various methods that robots use to transport themselves from place to place.
Forrest M. Mims III is an American amateur scientist, magazine columnist, and author of Getting Started in Electronics and Engineer's Mini-Notebook series of instructional books that were originally sold in Radio Shack electronics stores and are still in print. Mims graduated from Texas A&M University in 1966 with a major in government and minors in English and history. He became a commissioned officer in the United States Air Force, served in Vietnam as an Air Force intelligence officer (1967), and a Development Engineer at the Air Force Weapons Laboratory (1968–70).
Early flying machines include all forms of aircraft studied or constructed before the development of the modern aeroplane by 1910. The story of modern flight begins more than a century before the first successful manned aeroplane, and the earliest aircraft thousands of years before.
Bird flight is the primary mode of locomotion used by most bird species in which birds take off and fly. Flight assists birds with feeding, breeding, avoiding predators, and migrating.
The Invisible Plane is a plane appearing in DC Comics, commonly used by Wonder Woman as a mode of transport. It was created by William Moulton Marston and first appeared in Sensation Comics #1.
Félix du Temple de la Croix was a French naval officer and an inventor, born into an ancient Norman family. He developed some of the first flying machines and is credited with the first successful flight of a powered aircraft of any sort, a powered model plane, in 1857 and is sometimes credited with the first manned powered flight in history aboard his Monoplane in 1874.
James D. DeLaurier is an inventor and professor emeritus of the University of Toronto Institute for Aerospace Studies. He is a leader in design and analysis of lighter than air vehicles and flapping winged aircraft.
Around 350 BCE, Aristotle and other philosophers of the time attempted to explain the aerodynamics of avian flight. Even after the discovery of the ancestral bird Archaeopteryx which lived over 150 million years ago, debates still persist regarding the evolution of flight. There are three leading hypotheses pertaining to avian flight: Pouncing Proavis model, Cursorial model, and Arboreal model.
Clarence Odbody, also spelled Clarence Oddbody, is a guardian angel character in Frank Capra's 1946 film It's a Wonderful Life, where he was portrayed by Henry Travers, and in the 1990 sequel, Clarence, where he was played by Robert Carradine.
Robotics is the interdisciplinary study and practice of the design, construction, operation, and use of robots.
The Snowbird is a human-powered ornithopter that was built as a project of the University of Toronto Institute for Aerospace Studies (UTIAS). Snowbird was the first human-powered ornithopter to fly straight and level.
Outrageous Acts of Science is a science program shown on Science Channel in the United States, featuring a fast-paced countdown of the top 20 internet videos in each episode. The series first aired in the United Kingdom on Discovery International with the title You Have Been Warned. The program features homemade science experiments and stunts, often accompanied by warnings of "don't try this at home" when doing so might endanger the viewer. For the U.S. TV network, it was the top-rated show of 2015.
InterWorld is a trilogy of fantasy and science fiction novels written by Neil Gaiman, Michael Reaves and later Mallory Reaves. The books are published by EOS and HarperTeen, imprints of HarperCollins Publishers.
