Human Vision In Space

Intro Sample...


Human visual hardware is a result of a billion years of evolution within the earths atmosphere where light is scattered by molecules of air, moisture, particular matter etc. However as we ascend into our atmosphere with decrease density, light distribution is changed resulting in our visual hardware receiving visual data in different format. Some Aspects to Consider: 1. Visual acuity is the degree to which the details and contours of objects are perceived. Visual acuity is usually defined in terms of minimum separable.Large variety of factors influence this complex phenomenon which includes : # Optical factors- state of the image forming mechanisms of the eye. # Retinal factors such as the state of...

without stereoscopic vision "Empty field myopia" prevails. Empty Field Myopia is a condition in which the eyes, having nothing in the visual field upon which to focus, focus automatically at about 9 feet . An astronaut/cosmonaut experiencing empty field myopia focusing at 9 ft would be unable see objects at a range close as 100 ft. If another spacecraft, satellite, meteorite or L.E.M entered his field of vision, he would not be able to determine the size nor the distance. Solution: Man does not face any hostile environment in his birthday suit, the clothing industry and need for walk in closet say it all. In space we will wear our exoskeleton just as we wear winter jackets in winter and we will wear our helmets with visors to maintain our internal environment, filter out all those nasty rads etc. Since Empty Field Myopia is secondary to loss of reference points why not just build them into the visor itself giving the eye points of reference-- create a virtual reality ??? This line of speculation leads to amazing concepts...... To learn more about the concept of virtual universe in the helmet read: Journal: Air & Space, [smithsonian publication] article: Big Picture by Steven L.Thompson. illustrated by Dale Glasgow. About creation of virtual universe with new computer and software tech in the helmets of F-16 fighter pilots-- this is not a theoretical possibility but a reality. A MUST READ. Note: One aspect of adaptation to microgravity [space sickness] is an increased dependence on visual as opposed to vestibular mechanisms in the ...

    Space Exploration And The Space Race

    3970 words - 16 pages

    The Space Race was a competition of space exploration between the United States and Soviet Union, which lasted roughly from 1957 to 1975. It involved the efforts to explore outer space with artificial satellites, to send humans into space, and to land people on the Moon. Though its roots lie in early German rocket technology and in the international tensions following World War II, the Space Race effectively began after the Soviet launch of Sputnik 1 on 4 October 1957. The term originated as an analogy to the arms race. The Space Race became an important part of the cultural, technological,

    Frederick James The Limites Of Post Modern Theory

    5435 words - 22 pages

    The impetus behind this paper has been the recent publication of Fredric Jameson's 1991 Welleck Lectures, The Seeds of Time.1 As these lectures were delivered a decade after Jameson's initial attempts to map the terrain of postmodernity it appeared to me to provide an occasion to reflect upon the current status of Jameson's highly influential and much criticised theory of postmodernism as the cultural logic of late capitalism. It also enables me to return to, what I consider to be, one of the most troubling aspects of Jameson's writing on postmodernism, that is to say, the "waning",

    After months of research and experiments, I have concluded my discovery of space worm touch receptors is definite. Regardless of the type, sensory receptors are influenced by physical actions and various stimulus. My research and experiments show that space worm touch receptors are no different. Stimulus is a change discernible by the body (Sherwood 2004) or in my case, a space worm. Certain receptors like touch receptors respond to stimulus weakly or strongly when involved with a different stimulus (Sherwood 2004). This perfectly related to my experiment because t

    Occult Elements Of The Soul In A Vision

    Yeat's literary works received more publicity than his occult and mystic endeavors. However, he believed he owed much credit for his poetry to his studies of the occult. In July 1892, he wrote, "if I had not made magic my constant study I could not have written a single word of my Blake book, nor would The Countess Kathleen have ever come to exist. The mystical life is the centre of all that I do and all that I think and all that I write"(Ellmann 97). Yeats was never in his life satisfied with conventional life. His need for a form of religion was appeased through magic and mysticism. Howev
