Motion simulatorA motion simulator or motion platform is a mechanism that creates the feelings of being in a real motion environment. In a simulator, the movement is synchronised with a visual display of the outside world (OTW) scene. Motion platforms can provide movement in all of the six degrees of freedom (DOF) that can be experienced by an object that is free to move, such as an aircraft or spacecraft:. These are the three rotational degrees of freedom (roll, pitch, yaw) and three translational or linear degrees of freedom (surge, heave, sway).
Hypothèse de simulationvignette|The Matrix - Capture d'écran du célèbre économiseur d'écran GLMatrix L'hypothèse de simulation énonce que la réalité observable a pour trame une simulation, semblable à celles de nos ordinateurs, sans que les entités y évoluant puissent la distinguer commodément de la vraie réalité. Cette hypothèse repose elle-même sur le développement de la réalité simulée, actuellement considérée comme une technologie fictive et gravitant autour de nombreuses œuvres de science-fiction, telles Star Trek, eXistenZ, Passé virtuel ou Matrix.
Quiet PCA quiet, silent or fanless PC is a personal computer that makes very little or no noise. Common uses for quiet PCs include video editing, sound mixing and home theater PCs, but noise reduction techniques can also be used to greatly reduce the noise from servers. There is currently no standard definition for a "quiet PC", and the term is generally not used in a business context, but by individuals and the businesses catering to them.
