Confirmation Bias

Confirmation bias is the tendency to search for, interpret, favor, and recall information in a way that confirms or supports one's prior beliefs or values. People display this bias when they select information that supports their views, ignoring contrary information, or when they interpret ambiguous evidence as supporting their existing attitudes. The effect is strongest … Continue reading Confirmation Bias

Optical Computing

Optical computing uses photons produced by lasers or diodes for computation. For decades, photons have shown promise to enable a higher bandwidth than the electrons used in conventional computers. The fundamental building block of modern electronic computers is the transistor. To replace electronic components with optical ones, an equivalent optical transistor is required. This is … Continue reading Optical Computing

Aleph Number

Aleph numbers are a sequence of numbers used to represent the cardinality (or size) of infinite sets that can be well-ordered. The cardinality of the natural numbers is ℵ0. Examples of such sets are: the set of all integers,any infinite subset of the integers, such as the set of all square numbers or the set of all prime numbers,the set of all rational numbers,the set of … Continue reading Aleph Number

Neuroregenaration

Neuroregeneration refers to the regrowth or repair of nervous tissues, cells or cell products. Such mechanisms may include generation of new neurons, glia, axons, myelin, or synapses. Neuroregeneration differs between the peripheral nervous system (PNS) and the central nervous system (CNS) by the functional mechanisms involved, especially in the extent and speed of repair. Neuroregeneration … Continue reading Neuroregenaration

Nanoelectronics

Nanoelectronics refers to the use of nanotechnology in electronic components. The term covers a diverse set of devices and materials, with the common characteristic that they are so small that inter-atomic interactions and quantum mechanical properties need to be studied extensively. Nanofabrication which is for example, electron transistors, which involve transistor operation based on a … Continue reading Nanoelectronics

Chemical Composition Of Meteorites

Meteorites are the remains of space rocks that have fallen to Earths surface (a space rock still in space is termed a meteoroid , and when it is plunging through Earths atmosphere it is termed a meteor) . The small number of meteorites that survive vaporization in the atmosphere relatively intact give a picture of … Continue reading Chemical Composition Of Meteorites

Space Probe

Space probe, or simply probe, is a robotic spacecraft that doesn't orbit the Earth, but instead explores farther into outer space. A space probe may approach the Moon; travel through interplanetary space; flyby, orbit, or land or fly on other planetary bodies; or enter interstellar space. Once a probe has left the vicinity of Earth, … Continue reading Space Probe

Nuclear Star Cluster

Nuclear star cluster (NSC) or compact stellar nucleus is a star cluster with high density and high luminosity near the center of mass of most galaxies. NSCs are the central massive objects of fainter, low-mass galaxies where supermassive black holes (SMBHs) are not present or are of negligible mass. In the most massive galaxies, NSCs are entirely absent. Some galaxies, including the Milky Way, are known to contain … Continue reading Nuclear Star Cluster

Déjà vu

Déjà vu is a word expressing when you have done something and you experience the same feelings or the feeling that one has lived through the present situation before. It is an anomaly of memory whereby, despite the strong sense of recollection, the time, place, and practical context of the "previous" experience are uncertain or … Continue reading Déjà vu
