A Science Lesson In How Contacts Correct Vision Problems

Sunlight ... When the direct solar radiation is not blocked by clouds, it is experienced as sunshine, a combination of bright light and radiant heat. When it is blocked by the clouds or reflects off of other objects, it is experienced as diffused light...

Virtual Reality ... He built a prototype of his vision dubbed the Sensorama in 1962, along with five short films to be displayed in it while engaging multiple senses (sight, sound, smell, and touch)...

Photonics ... Photonics as a field began with the invention of the laser in 1960. Other developments followed: including the laser diode in the 1970s, optical fibers for transmitting information, and the Erbium-doped fiber amplifier...

Service-oriented Architecture ... SOA generally provides a way for consumers of services, such as web-based applications, to be aware of available SOA-based services. For example, several disparate departments within a company may develop and deploy SOA services in different implementation languages; their respective clients will benefit from a well-understood, well-defined interface to access them...

Wearable Technology ... The calculator watch, introduced in the 1980s, was one original piece of widespread worn electronics. Ilya Fridman designed a Bluetooth headset into a pair of earrings with a hidden microphone...

Artificial Intelligence ... The field was founded on the claim that a central property of humans, intelligence—the sapience of Homo sapiens—can be so precisely described that it can be simulated by a machine. This raises philosophical issues about the nature of the mind and the ethics of creating artificial beings, issues which have been addressed by myth, fiction and philosophy since antiquity...

Gene Therapy ... Gene therapy was first conceptualized in 1972, with the authors urging caution before commencing gene therapy studies in humans. The first FDA-approved gene therapy experiment in the United States occurred in 1990, when Ashanti DeSilva was treated for ADA-SCID...

Color Photography ... Three-color processes The three-color method, which is the foundation of virtually all practical color processes whether chemical or electronic, was first suggested in an 1855 paper on color vision by Scottish physicist James Clerk Maxwell...

BT Vision ... BT Vision is a "hybrid" transmission service; it delivers TV channels on the digital terrestrial (DVB-T) platform (using a Freeview decoder) and on-demand content via IPTV through a hybrid DTT/IP/PVR set-top box, known as the Vision+... BT Vision requires access to a BT Broadband internet connection with BT's official router (BT Home Hub) to watch programmes, and does not use the customer's broadband allowance... Launch BT Vision was launched on 5 December 2006, competing with Sky, Virgin Media and TalkTalk TV (then known as Tiscali TV)...

Vision – From The Life Of Hildegard Von Bingen ... The film reunites von Trotta with Barbara Sukowa (Zentropa, Berlin Alexanderplatz). Sukowa portrays Hildegard’s fierce determination to expand the responsibilities of women within the Benedictine order, as she fends off outrage from the Church over the visions she claims to receive from God...

Machine Vision ... However, the editor-in-chief of an MV trade magazine asserted that "machine vision is not an industry per se" but rather "the integration of technologies and products that provide services or applications that benefit true industries such as automotive or consumer goods manufacturing, agriculture, and defense." As of 2006, experts estimated that MV had been employed in less than 20% of the applications for which it is potentially useful...

Optics ... Most optical phenomena can be accounted for using the classical electromagnetic description of light. Complete electromagnetic descriptions of light are, however, often difficult to apply in practice...

Biotechnology ... For thousands of years, humans have used selective breeding to improve production of crops and livestock to use them for food. In selective breeding, organisms with desirable characteristics are mated to produce offspring with the same characteristics...

Management ... Since organizations can be viewed as systems, management can also be defined as human action, including design, to facilitate the production of useful outcomes from a system. This view opens the opportunity to 'manage' oneself, a pre-requisite to attempting to manage others...

Least Distance Of Distinct Vision ... LDDV and lenses The LDDV is used to define the magnifying power (M) of a lens with focal length (f in millimeters) when viewed by the naked human eye: 20ft LDDV and Snellen charts Snellen charts refer to someone with 20/20 vision being able to discriminate spatial patterns separated by a visual angle of 1 minute of arc (1/60th of a degree)... This is the same as someone with 20/20 vision is able to comfortably view a dot of 73 µm at 250 mm: ...

History Of Optics ... Some lenses fixed in ancient Egyptian statues are much older than those mentioned above. There is some doubt as to whether or not they qualify as lenses, but they are undoubtedly glass and served at least ornamental purposes...

Molecular Nanotechnology ... A roadmap for the development of MNT is an objective of a broadly based technology project led by Battelle (the manager of several U. S. National Laboratories) and the Foresight Institute...

Nanotechnology ... Nanotechnology is very diverse, ranging from extensions of conventional device physics to completely new approaches based upon molecular self-assembly, from developing new materials with dimensions on the nanoscale to direct control of matter on the atomic scale. Nanotechnology entails the application of fields of science as diverse as surface science, organic chemistry, molecular biology, semiconductor physics, microfabrication, etc...
