NeuroscienceNeuroscience is the scientific study of the nervous system (the brain, spinal cord, and peripheral nervous system), its functions and disorders. It is a multidisciplinary science that combines physiology, anatomy, molecular biology, developmental biology, cytology, psychology, physics, computer science, chemistry, medicine, statistics, and mathematical modeling to understand the fundamental and emergent properties of neurons, glia and neural circuits.
Laser diodeA laser diode (LD, also injection laser diode or ILD, or diode laser) is a semiconductor device similar to a light-emitting diode in which a diode pumped directly with electrical current can create lasing conditions at the diode's junction. Driven by voltage, the doped p–n-transition allows for recombination of an electron with a hole. Due to the drop of the electron from a higher energy level to a lower one, radiation, in the form of an emitted photon is generated. This is spontaneous emission.
Media cultureIn cultural studies, media culture refers to the current Western capitalist society that emerged and developed from the 20th century, under the influence of mass media. The term alludes to the overall impact and intellectual guidance exerted by the media (primarily TV, but also the press, radio and cinema), not only on public opinion but also on tastes and values. The alternative term mass culture conveys the idea that such culture emerges spontaneously from the masses themselves, like popular art did before the 20th century.
Influence of mass mediaIn media studies, mass communication, media psychology, communication theory, and sociology, media influence and the media effect are topics relating to mass media and media culture's effects on individuals' or audiences' thoughts, attitudes, and behaviors. Through written, televised, or spoken channels, mass media reach large audiences. Mass media's role in shaping modern culture is a central issue for the study of culture. Media influence is the actual force exerted by a media message, resulting in either a change or reinforcement in audience or individual beliefs.
