@Photography -- #Art Gallery Fans 17499264 and 0 are talking about this page Photography is the science, art, application and practice of creating durable images by recording light or other electromagnetic radiation, either electronically by means of an image sensor, or chemically by means of a light-sensitive material such as photographic film.Typically, a lens is used to focus the light reflected or emitted from objects into a real image on the light-sensitive surface inside a camera during a timed exposure. With an electronic image sensor, this produces an electrical charge at each pixel, which is electronically processed and stored in a digital image file for subsequent display or processing. The result with photographic emulsion is an invisible latent image, which is later chemically "developed" into a visible image, either negative or positive depending on the purpose of the photographic material and the method of processing. A negative image on film is traditionally used to photographically create a positive image on a paper base, known as a print, either by using an enlarger or by contact printing.
@Κινηματογράφος -- #Movie Fans 15849863 and 0 are talking about this page A film, also called a movie, motion picture, theatrical film or photoplay, is a series of still images which, when shown on a screen, creates the illusion of moving images due to the phi phenomenon. This optical illusion causes the audience to perceive continuous motion between separate objects viewed rapidly in succession. The process of filmmaking is both an art and an industry. A film is created by photographing actual scenes with a motion picture camera; by photographing drawings or miniature models using traditional animation techniques; by means of CGI and computer animation; or by a combination of some or all of these techniques and other visual effects.The word "cinema", short for cinematography, is often used to refer to the industry of films and filmmaking or to the art of filmmaking itself. The contemporary definition of cinema is the art of simulating experiences to communicate ideas, stories, perceptions, feelings, beauty or atmosphere by the means of recorded or programmed moving images along with other sensory stimulations.Films were originally recorded onto plastic film through a photochemical process and then shown through a movie projector onto a large screen. The adoption of CGI-based special effects led to the use of digital intermediates. Most contemporary films are now fully digital through the entire process of production, distribution, and exhibition from start to finish. Films recorded in a photochemical form traditionally included an analogous optical soundtrack, which is a graphic recording of the spoken words, music and other sounds that accompany the images. It runs along a portion of the film exclusively reserved for it and is not projected.
@Chemistry -- #Field of Study Fans 635662 and 0 are talking about this page Chemistry is a branch of physical science that studies the composition, structure, properties and change of matter. Chemistry includes topics such as the properties of individual atoms, how atoms form chemical bonds to create chemical compounds, the interactions of substances through intermolecular forces that give matter its general properties, and the interactions between substances through chemical reactions to form different substances.Chemistry is sometimes called the central science because it bridges other natural sciences, including physics, geology and biology. For the differences between chemistry and physics see comparison of chemistry and physics.The history of chemistry can be traced to alchemy, which had been practiced for several millennia in various parts of the world.EtymologyThe word chemistry comes from alchemy, which referred to an earlier set of practices that encompassed elements of chemistry, metallurgy, philosophy, astrology, astronomy, mysticism and medicine. It is often seen as linked to the quest to turn lead or another common starting material into gold, though in ancient times the study encompassed many of the questions of modern chemistry being defined as the study of the composition of waters, movement, growth, embodying, disembodying, drawing the spirits from bodies and bonding the spirits within bodies by the early 4th century Greek-Egyptian alchemist Zosimos. An alchemist was called a ´chemist´ in popular speech, and later the suffix "-ry" was added to this to describe the art of the chemist as "chemistry".
@Computer science -- #Interest Fans 605415 and 0 are talking about this page Computer science is the study of the theory, experimentation, and engineering that form the basis for the design and use of computers. It is the scientific and practical approach to computation and its applications and the systematic study of the feasibility, structure, expression, and mechanization of the methodical procedures (or algorithms) that underlie the acquisition, representation, processing, storage, communication of, and access to information. An alternate, more succinct definition of computer science is the study of automating algorithmic processes that scale. A computer scientist specializes in the theory of computation and the design of computational systems.Its fields can be divided into a variety of theoretical and practical disciplines. Some fields, such as computational complexity theory (which explores the fundamental properties of computational and intractable problems), are highly abstract, while fields such as computer graphics emphasize real-world visual applications. Other fields still focus on challenges in implementing computation. For example, programming language theory considers various approaches to the description of computation, while the study of computer programming itself investigates various aspects of the use of programming language and complex systems. Human–computer interaction considers the challenges in making computers and computations useful, usable, and universally accessible to humans.
@Medicine -- #Business Service Fans 560030 and 0 are talking about this page Medicine is the science and practice of the diagnosis, treatment, and prevention of disease. The word "medicine" is derived from Latin medicus, meaning "a physician". Medicine encompasses a variety of health care practices evolved to maintain and restore health by the prevention and treatment of illness. Contemporary medicine applies biomedical sciences, biomedical research, genetics, and medical technology to diagnose, treat, and prevent injury and disease, typically through pharmaceuticals or surgery, but also through therapies as diverse as psychotherapy, external splints and traction, medical devices, biologics, and ionizing radiation, amongst others.
@Psicologia -- #Interest Fans 236944 and 0 are talking about this page Psicologia é a ciência que estuda o comportamento e as funções mentais. A psicologia tem como objetivo imediato a compreensão de grupos e indivíduos tanto pelo estabelecimento de princípios universais como pelo estudo de casos específicos, e tem, segundo alguns, como objetivo final o benefício geral da sociedade. Um pesquisador ou profissional desse campo é conhecido como psicólogo, podendo ser classificado como cientista social, comportamental ou cognitivo. A função dos psicólogos é tentar compreender o papel das funções mentais no comportamento individual e social, estudando também os processos fisiológicos e biológicos que acompanham os comportamentos e funções cognitivas.Psicólogos exploram conceitos como percepção, cognição, atenção, emoção, Inteligência, fenomenologia, motivação, funcionamento do cérebro humano, personalidade, comportamento, relacionamentos interpessoais, incluindo resiliência, entre outras áreas. Psicólogos de orientações diversas também estudam conceitos como o inconsciente e seus diferentes modelos.
@Astrophysics -- #Interest Fans 189677 and 0 are talking about this page Astrophysics is the branch of astronomy that employs the principles of physics and chemistry "to ascertain the nature of the heavenly bodies, rather than their positions or motions in space." Among the objects studied are the Sun, other stars, galaxies, extrasolar planets, the interstellar medium and the cosmic microwave background. Their emissions are examined across all parts of the electromagnetic spectrum, and the properties examined include luminosity, density, temperature, and chemical composition. Because astrophysics is a very broad subject, astrophysicists typically apply many disciplines of physics, including mechanics, electromagnetism, statistical mechanics, thermodynamics, quantum mechanics, relativity, nuclear and particle physics, and atomic and molecular physics.
@Μηχανική υπολογιστών -- #Concentration or Major Fans 188645 and 0 are talking about this page Computer engineering is a discipline that integrates several fields of electrical engineering and computer science required to develop computer hardware and software. Computer engineers usually have training in electronic engineering (or electrical engineering), software design, and hardware-software integration instead of only software engineering or electronic engineering. Computer engineers are involved in many hardware and software aspects of computing, from the design of individual microcontrollers, microprocessors, personal computers, and supercomputers, to circuit design. This field of engineering not only focuses on how computer systems themselves work, but also how they integrate into the larger picture.Usual tasks involving computer engineers include writing software and firmware for embedded microcontrollers, designing VLSI chips, designing analog sensors, designing mixed signal circuit boards, and designing operating systems. Computer engineers are also suited for robotics research, which relies heavily on using digital systems to control and monitor electrical systems like motors, communications, and sensors.
@Ηλεκτρονικός μηχανικός -- #Education Fans 187069 and 0 are talking about this page Electronics engineering, or electronic engineering, is an electrical engineering discipline which utilizes non-linear and active electrical components (such as semiconductor devices, especially transistors, diodes and integrated circuits) to design electronic circuits, devices, microprocessors, microcontrollers and other systems. The discipline typically also designs passive electrical components, usually based on printed circuit boards.Electronics is a subfield within the wider electrical engineering academic subject but denotes a broad engineering field that covers subfields such as analog electronics, digital electronics, consumer electronics, embedded systems and power electronics. Electronics engineering deals with implementation of applications, principles and algorithms developed within many related fields, for example solid-state physics, radio engineering, telecommunications, control systems, signal processing, systems engineering, computer engineering, instrumentation engineering, electric power control, robotics, and many others.
@Creative writing -- #Interest Fans 166426 and 0 are talking about this page Creative writing is any writing that goes outside the bounds of normal professional, journalistic, academic, or technical forms of literature, typically identified by an emphasis on narrative craft, character development, and the use of literary tropes or with various traditions of poetry and poetics. Due to the looseness of the definition, it is possible for writing such as feature stories to be considered creative writing, even though they fall under journalism, because the content of features is specifically focused on narrative and character development. Both fictional and non-fictional works fall into this category, including such forms as novels, biographies, short stories, and poems. In the academic setting, creative writing is typically separated into fiction and poetry classes, with a focus on writing in an original style, as opposed to imitating pre-existing genres such as crime or horror. Writing for the screen and stage—screenwriting and playwrighting—are often taught separately, but fit under the creative writing category as well.
