Engineering ... The American Engineers' Council for Professional Development (ECPD, the predecessor of ABET) has defined "engineering" as: The creative application of scientific principles to design or develop structures, machines, apparatus, or manufacturing processes, or works utilizing them singly or in combination; or to construct or operate the same with full cognizance of their design; or to forecast their behavior under specific operating conditions; all as respects an intended function, economics of operation and safety to life and property.. ...
Wireless Telegraphy ... Wireless telegraphy originated as a term to describe electrical signaling without the electric wires to connect the end points. The intent was to distinguish it from the conventional electric telegraph signaling of the day that required wire connection between the end points...
Timeline Of Chemistry ... Early ideas that later became incorporated into the modern science of chemistry come from two main sources. Natural philosophers (such as Aristotle and Democritus) used deductive reasoning in an attempt to explain the behavior of the world around them...
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...
History Of Astronomy ... Ancient astronomers were able to differentiate between stars and planets, as stars remain relatively fixed over the centuries while planets will move an appreciable amount during a comparatively short time. Early history Early cultures identified celestial objects with gods and spirits...
Wireless Energy Transfer ... The most common form of wireless power transmission is carried out using direct induction followed by resonant magnetic induction. Other methods under consideration include electromagnetic radiation in the form of microwaves or lasers...
Future ... In the philosophy of time, presentism is the belief that only the present exists and the future and the past are unreal. Religions consider the future when they address issues such as karma, life after death, and eschatologies that study what the end of time and the end of the world will be...
Nobel Prize In Chemistry ... The members of the Norwegian Nobel Committee that were to award the Peace Prize were appointed shortly after the will was approved. The prize-awarding organisations followed: the Karolinska Institutet on June 7, the Swedish Academy on June 9, and the Royal Swedish Academy of Sciences on June 11...
Computer Vision ... Applications range from tasks such as industrial machine vision systems which, say, inspect bottles speeding by on a production line, to research into artificial intelligence and computers or robots that can comprehend the world around them. The computer vision and machine vision fields have significant overlap...
Color Photography ... In color photography, light-sensitive chemicals or electronic sensors record color information at the time of exposure. This is usually done by analyzing the spectrum of colors into three channels of information, one dominated by red, another by green and the third by blue, in imitation of the way the normal human eye senses color...
History Of Technology ... Technological artifacts are products of an economy, a force for economic growth, and a large part of everyday life. Technological innovations affect, and are affected by, a society's cultural traditions...
History Of Chemistry ... Early attempts to explain the nature of matter and its transformations failed. The protoscience of chemistry, Alchemy, was also unsuccessful in explaining the nature of matter...
Theoretical Astronomy ... "So how can one be sure that what one sees out there is subject to the same rules and disciplines of science that govern the local laboratory experiments of physics and chemistry?" "The most incomprehensible thing about the universe is that it is comprehensible." – Albert Einstein... Integrating astronomy and physics "Contrary to the belief generally held by laboratory physicists, astronomy has contributed to the growth of our understanding of physics." Physics has helped in the elucidation of astronomical phenomena, and astronomy has helped in the elucidation of physical phenomena: discovery of the law of gravitation came from the information provided by the motion of the Moon and the planets, viability of nuclear fusion as demonstrated in the Sun and stars and yet to be reproduced on Earth in a controlled form... Integrating astronomy with physics involves Physical interaction Astronomical phenomena Electromagnetism: observation using the electromagnetic spec...
Energy ... The total energy contained in an object is identified with its mass, and energy (like mass), cannot be created or destroyed. When matter (ordinary material particles) is changed into energy (such as energy of motion, or into radiation), the mass of the system does not change through the transformation process...
Celestial Mechanics ... In the 9th century CE, the Persian physicist and astronomer, Ja'far Muhammad ibn Mūsā ibn Shākir, hypothesized that the heavenly bodies and celestial spheres are subject to the same laws of physics as Earth, unlike the ancients who believed that the celestial spheres followed their own set of physical laws different from that of Earth...
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...
Solar Neutrino Problem ... As neutrino detectors became sensitive enough to measure the flow of neutrinos from the Sun, it became clear that the number detected was lower than that predicted by models of the solar interior. In various experiments, the number of detected neutrinos was between one third and one half of the predicted number...
Superposition Principle ... In physics and systems theory, the superposition principle, also known as superposition property, states that, for all linear systems, the net response at a given place and time caused by two or more stimuli is the sum of the responses which would have been caused by each stimulus individually...
International Space Station ... The ISS serves as a microgravity and space environment research laboratory in which crew members conduct experiments in biology, human biology, physics, astronomy, meteorology and other fields. The station is suited for the testing of spacecraft systems and equipment required for missions to the Moon and Mars...
