 Thermal Imaging is a method of using infrared radiation and thermal energy to gather information about objects, in order to formulate images of them, even in low visibility environments. It’s a type of technology that has built up a broad range of uses

 The human retina is a thin tissue composed of neuralcells that is located in the posterior portion of the eye.The retina is a light-sensitive layer in the back of the eye that contains highly evolved cells called rods and cones. It’s divided into

 Data Centers are simply centralized locations where computing and networking equipment is concentrated for the purpose of collecting, storing, processing, distributing or allowing access to large amounts of data. They have existed in one form or another since the advent of computers.In the

 Cultured meat is meat produced by in vitro cultivation of animal cells, instead of from slaughtered animals. It is a form of cellular agriculture.Cultured meat is produced using many of the same tissue engineering techniques traditionally used in regenerative medicine.The concept of cultured

 Smelting is the process of extracting a metal (like tin or copper) from its ore. Most ores are a chemical compound of metal with other elements, like or oxygen sulphur. For example, zinc is more reactive than copper so it has to be
