Electricity generation  is a method of generating electric power from sources of primary energy. For utilities in the electric power industry, it is the stage prior to its delivery (transmission, distribution, etc.) to end users or its storage. For example, the pumped-storage method. Electricity is not freely available in nature, so it must be "produced" (that is, transforming other forms of energy to electricity--transformation of energy). Production is carried out in power stations (also called "power plants"). Electricity is most often generated at a power plant by electromechanical generators, primarily driven by heat engines fueled by combustion or nuclear fission but also by other means such as the kinetic energy of flowing water and wind. Other energy sources include solar photovoltaics and geothermal power. There are also exotic and speculat...

  What is Cancer? Cancer is a large group of diseases that can start in almost any organ or tissue of the body when abnormal cells grow uncontrollably, go beyond their usual areas to invade adjoining parts of the body or spread to other organs. It  is  a disease in which some of the body's cells grow uncontrollably and spread to other parts of the body . Cancer can start almost anywhere in the human body, which is made up of trillions of cells. Sometimes tumar can be the first appearence of cancer. Causes of tumar is Defective P53 protin. Symptoms were names after the crab because the finger-like spreading projections from a cancer called to mind the shape of a crab . Later Roman physician, Celsus  translated the Greek term into cancer, the Latin word for crab. Cancer is caused by changes (mutations) to the DNA (De-oxyribo Nuclic Acid) within cells. The DNA inside a cell is packaged into a large number of individual genes, each of which contains a set of instruction...

  Artificial Intelligence is  a technic that's build a computer, a computer-controlled robot or a software which can imagine intelligently like the human thinking . AI  performed by studying the patterns of the human brain and by analyzing the cognitional  system. The successful outcome of these studies develops intelligent software and systems. It  is the ability of a  computer or a robot  controlled by a computer to do tasks that are usually done by humans because they require human intelligence and discernment. Though there are no AIs that can perform the wide variety of tasks an ordinary human can do, some AIs can match humans in specific tasks.  In the simplest form, artificial intelligence is a field, that connects  computer science and robust datasets, to enable problem-solving. It also encompasses sub-fields of machine learning and deep learning, which are frequently mentioned in conjunction with artificial intelligenc...

  They're some of the most violent objects in our universe,  powerful enough to rip entire stars to pieces . Their secret weapon is gravity. You see, the more mass you can shrink into a small space, the stronger your gravitational force will become. Do you get touch, what thing I talk about? The answer is Black hole.  Black hole is a hilarious & iconic invention in space of modern science. So, let's know a little bit about Black hole. The words “black hole“ was coined in 1968 by the Princeton physicist John Wheeler , which man worked out everything details of a black hole's properties. The most common black holes are probably formed by the collapse of massive stars.   The  Black holes have two parts. There is  the event horizon, which you can think of as the surface, though it's simply the point where the gravity(accelaration due to gravity) gets too strong for anything to escape.   And other part is at the center, which is the singularity . That's...
