A wave is a disturbance that propagates in a periodically repeating fashion, often transferring energy. A mechanical wave exists in a medium (which on deformation is capable of producing elastic restoring forces) through which they travel and can transfer energy from one place to another without any of the particles of the medium being displaced permanently; there is no associated mass transport. Instead, any particular point oscillates around a fixed position. However, electromagnetic radiation, and probably gravitational radiation are not mechanical waves, and can ...

Alessio Guarino is an Italian physicist. Born in Florence. He works on the domain of nonlinear physics such as liquid crystals, fracture, convection and granular matter. With Sergio Ciliberto and Riccardo Scorretti, he introduced a new numerical technique to study the effect of thermal fluctuations in heterogeneous systems. He is now with the University of French Polynesia in Tahiti. He was previously at the University of California, Santa Barbara and the Ecole Normale Superieure de Lyon [1]. Currently, with collegues Duccio Fanelli o

Many natural phenomena may be called complex systems, and complexity science is highly interdisciplinary. Examples of complex systems include ant-hills, ants themselves, human economies, nervous systems, cells and so forth, as well as human beings and their psychology, emotions, bodies and interactions. Beyond the fact that these things are all networks of some kind, and that they are complex, it may appear that they have little in common, and hence that the term "complex system" is vacuous. However, all complex systems ...

A mouse is a handheld pointing device for computers, being a small object fitted with one or more buttons and shaped to sit naturally under the hand. The underside of the mouse houses a device that detects the mouse's motion relative to the flat surface on which it moves. The mouse's 2D motion is typically translated into the motion of a pointer on the display. It is called a mouse primarily because the cord on early models resembled the rodent's tail, and also because the motion of the pointer on the screen can be mouse-like.< ...

In mathematics and physics, chaos theory deals with the behavior of certain nonlinear dynamic systems that under certain conditions exhibit a phenomenon known as chaos, which is characterised by a sensitivity to initial conditions (see butterfly effect). As a result of this sensitivity, the behavior of systems that exhibit chaos appears to be random, even though the model of the system is determ ...

The most basic trade-off in the human experience is what you do with your time. In any given period, you can focus mainly on only will earn you more money, or is more pleasurable to you, than mowing the lawn. This gives rise to the common idiom that time is money. The downside of this trade-off is that you don't have your money anymore. A classic trade-off in business is the trio of time, money and quality. It is generally considered that only two of the three can be anchored at any given moment. Given enough money and attention to ...

A non-linear dynamical system can exhibit one or more of the following types of behavior: forever at rest forever expanding (only for unbounded systems) periodic motion quasi-periodic motion chaotic motion The type of behavior a system may exhibit depends on the initial state of the system and the values of its parameters, if any. The most difficult type of behavior to characterize and predict is chaotic motion, a non-periodic complex motion, for which the theory is named.See also:

Pharmacokinetics has many applications in drug therapy. By studying absorption -- the amount of a drug which gets into the system (bloodstream) following administration -- pharmacokinetics may guide the formulation of drug products. The amount of drug released from different formulations may vary; for example, two different tablets containing the same amount of drug chemical may not release the same amount into the bloodstream; a pharmacokinetic absorption study can determine whether or not ...

The native population is Polynesian, and is estimated to have settled on the island sometime between AD 300 and 800, although some estimates place the date earlier. The fertile island soil combined with fishing provided ample food for the population with ease. The perceived relaxed and contented nature of the local people and the characterization of the island as a paradise much impressed early European visitors, planting the seed for a romanticization by ...

The interaction of light with matter in a linear regime allows the absorption or simultaneous emission of light of energy precisely matching the difference in energy levels of the interacting electrons. The Raman effect is a nonlinear (third order) effect. The Raman effect corresponds, in perturbation theory, to the absorption and subsequent emission of a photon via an intermediate electron state, having a virtual energy level (see also: Feynman diagram). There are three possibilities : no energy exchange between the ...

An aeroplane can be made to stall in any pitch attitude or bank angle or at any airspeed but is commonly practised by reducing the speed to the stall speed, at a safe altitude. Stall speed varies on different airplanes and is represented by color codes on the air speed indicator. As the plane flies at this speed the angle of attack must be increased to prevent any loss of altitude or gain in airspeed (which corresponds to the stall angle described above). The pilot will notice the flight controls have become less responsive and may also notice some buffeting, an aerodynamic vibrat ...

Don is an FBI Special Agent who recruits his mathematical genius brother, Charlie Eppes, to help him and the Bureau solve some of their most difficult cases. Don makes great sacrifices in his personal life in order to devote himself to his career, which to him is more of a way of life than a mere job. More important to him than his work is his family, especially Charlie, even though he doesn't understand his brother's way of look ...

The neuroethological approach stems from the idea that animals' nervous systems have evolved to address problems of sensing and acting in certain environmental niches. So echolocating bats use ultrasound to navigate and hunt in darkness, while humans use sound mainly for communication. Nervous systems, therefore, are best understood in the context of the problems they have evolved to solve. Other approaches to understanding nervous sytems include the systems identification approach, popular in engineering. The idea is to stimulate the ...

The HSV model is commonly used in computer graphics applications. In various application contexts, a user must choose a color to be applied to a particular graphical element. When used in this way, the HSV color wheel is often used. In it, the hue is represented by a circular region; a separate triangular region may be used to represent saturation and value. Typically, the vertical axis of the triangle indicates saturation, while the horizontal axis corresponds to value. In this way, a color can be chosen by first picking the hue from the circular region, then selecting the ...

To use the groundwater flow equation to estimate the distribution of hydraulic heads, or the direction and rate of groundwater flow, this partial differential equation (PDE) must be solved. The most common means of analytically solving the diffusion equation in the hydrogeology literature are: Laplace and Fourier transforms (to reduce the number of dimensions of the PDE), similarity transform (also called the Boltzmann transform) is commonly how the Theis solution is derived, separation of variables, which is m ...

Linear algebra had its beginnings in the study of vectors in Cartesian 2-space and 3-space. A vector, here, is a directed line segment, characterized by both its magnitude represented by length, and its direction. Vectors can be used to represent physical entities such as forces, and they can be added and multiplied with scalars, thus forming the first example of a real vector space. Modern linear algebra has been extended to consider spaces of arbitrary or infinite dimension. A vector space of dimension n is called an n ...

The original Metroid was released for the Nintendo Entertainment System (NES) in 1986, introducing Samus Aran (who at the time was unusual in being a female video game character. In fact, the advertisments and instruction manual described Samus as male in order to surprise players when the truth was revealed) and other characters that appear in subsequent Metroid games. Featuring a labyrinthine world in which the player chooses which direction to explore, it was notable for providing one of the first highly nonlinear gam ...
