A synthetic element is one of 24 known chemical elements that do not occur naturally on Earth: they have been created by human manipulation of fundamental particles in a nuclear reactor, a particle accelerator, or the explosion of an atomic bomb; thus, they are called "synthetic", "artificial", or "man-made".The synthetic elements are those with atomic numbers 95–118, as …

Synthetic biology (SynBio) is a multidisciplinary area of research that seeks to create new biological parts, devices, and systems, or to redesign systems that are already found in nature.. It is a branch of science that encompasses a broad range of methodologies from various disciplines, such as biotechnology, biomaterials, material science/engineering, genetic engineering, …

A synthetic language uses inflection or agglutination to express syntactic relationships within a sentence. Inflection is the addition of morphemes to a root word that assigns grammatical property to that word, while agglutination is the combination of two or more morphemes into one word. The information added by morphemes can include indications of a word's grammatical category, …

Synthetic-aperture radar (SAR) is a form of radar that is used to create two-dimensional images or three-dimensional reconstructions of objects, such as landscapes. SAR uses the motion of the radar antenna over a target region to provide finer spatial resolution than conventional stationary beam-scanning radars. SAR is typically mounted on a moving platform, such as an aircraft or …

The turkey is a large species of bird in the genus Meleagris, native to North America.There are two extant turkey species: the wild turkey (M. gallopavo) of eastern and central North America and the ocellated turkey (M. ocellata) of the Yucatán Peninsula in Mexico. This photograph, taken at Deer Island Preserve in Novato, California, depicts a male Rio Grande wild turkey (M. g. …

Chemistry is the scientific study of the properties and behavior of matter. It is a natural science that covers the elements that make up matter to the compounds composed of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during a reaction with other substances.. In the scope of its subject, chemistry occupies an …

Copernicium is a synthetic chemical element with the symbol Cn and atomic number 112. Its known isotopes are extremely radioactive, and have only been created in a laboratory.The most stable known isotope, copernicium-285, has a half-life of approximately 28 seconds. Copernicium was first created in 1996 by the GSI Helmholtz Centre for Heavy Ion Research …

Dubnium is a synthetic chemical element with the symbol Db and atomic number 105. It is highly radioactive: the most stable known isotope, dubnium-268, has a half-life of about 28 hours. This greatly limits extended research on the element. Dubnium does not occur naturally on Earth and is produced artificially.

The real element 99, einsteinium, has no such qualities. Element 115 Ufology, various works Widely known within the sci-fi and UFO community; since, according to ufologist Bob Lazar, it is used by alien engines to generate anti-gravity and propulsion. The real element 115 is moscovium, a synthetic element with an extremely short half-life ...

Silicon is a chemical element with the symbol Si and atomic number 14. It is a hard, brittle crystalline solid with a blue-grey metallic luster, and is a tetravalent metalloid and semiconductor.It is a member of group 14 in the periodic table: carbon is above it; and germanium, tin, lead, and flerovium are below it. It is relatively unreactive. ...
