  • A vector is a quantity that possesses both magnitude and direction. Examples of vector quantities are displacement, velocity, acceleration, and force. A vector quantity can be represented by an arrow drawn to scale. The length of the arrow is proportional to the magnitude of the vector quantity. The direction of the arrow represents the direction of the vector quantity.physics in general is the most scientific study of "physical" and "interaction".

  • Some people make physical chemistry sound more confusing than it really is. One of their best tricks is to define it inaccurately, saying it is ‘the physics of chemicals’. This definition is sometimes quite good, since it suggests we look at a chemical system and ascertain how it follows the laws of nature. This is true, but it suggests that chemistry is merely a sub-branch of physics; and the notoriously mathematical nature of physics impels us to avoid this otherwise useful way of looking at physical chemistry....

  • Science progresses by a symbiotic interaction between theory and experiment: theory is used to interpret experimental results and may suggest new experiments; experiment helps to test theoretical predictions and may lead to improved theories. Theoretical Chemistry (including Physical Chemistry and Chemical Physics) provides the concep- tual and technical background and apparatus for the rationalisation of phenomena in the chemical sciences. It is, therefore, a wide ranging subject, reflecting the diversity of molecular and related species and processes arising in chemical systems.

  • The physical basis of color exists in the interaction of light with matter, both outside and inside the eye. The sensation of color depends on physiological activity in the visual system that begins with the absorption of light in photoreceptors located in the retina of the eye and ends with patterns of biochemical activity in the brain. Perceived color can be described by the color names white, gray, black, yellow, orange, brown, red, green, blue, purple, and pink. These 11 basic color terms have unambiguous referents in all fully developed languages.

  • Cyber-physical systems (CPSs) are an emerging research topic born from the ever increasing complexity of engineered systems. Future systems will have to interact with each other and with the physical world in a very tight and well coordinated fashion, and designing such systems is the research challenge behind CPSs. CPSs have been defined as “computational thinking and integration of com putation around the physical dynamic systems where sensing, decision, actuation, computation, networking, and physical processes are mixed”.

  • Physics has an important role in our life. Without physics and the work of physicists, our modern life would not exist. Using physics, people created machines, instruments and some different divices from the crudest to the most modern aspect. Techology is developed more rapidly, more modern day by day. Moreover, all other natural sciences- example chemistry, biology, medicinedepend upon physics for the foundations of their knowledge.

  • The proposed book contains a lot of recent research devoted to numerical simulations of physical and engineering systems. It can be treated as a bridge linking various numerical approaches of two closely inter-related branches of science, i.e. physics and engineering. Since the numerical simulations play a key role in both theoretical and application-oriented research, professional reference books are highly required by pure research scientists, applied mathematicians, engineers as well post- graduate students....

  • The heart of any system that simulates the physical interaction between objects is collision detection-the ability to detect when two objects have come into contact. This system is also one of the most difficult aspects of a physical simulation to implement correctly, and invariably it is the main consumer of CPU cycles. Practitioners, new to the field or otherwise, quickly discover that the attempt to build a fast, accurate, and robust collision detection system takes them down a long path fraught with perils and pitfalls unlike most they have ever encountered.

  • We present the appearance of some new interaction in the MSSM with CP violation. We give analytic formulae and perform an evaluation of the effects of these new interactions on some processes concerning the productions and decays of squarks. We find that these effects are typically of $-3.5 \% $ to $+3 \% $ depending on each process.

  • Using Greens function method and the equation of motion approach, we have investigated the electronic transport properties of an Aharonov-Bohm (AB) ring in the presence of a magnetic field with a quantum dot inserted in one arm of the ring. In particular, we consider the electron-electron Coulomb interaction within the quantum dot. We find that the current through the system is dependent on the magnetic flux via the AB phase and the Coulomb interaction within the quantum dot, in agreement with experiments. Furthermore, the intradot Coulomb interaction induces dephasing. ...

  • Reliable gene-lifestyle interaction studies will yield important evidence for the shaping of personalised healthcare. Studies need statistical power with adequate environmental exposures and lifestyle heterogeneity to obtain reliable evidence on the interplay between nurture and nature. Europe has a historic strength in large epidemiological studies but technology development and implementation is needed to better ascertain environmental exposure and dietary heterogeneity.

  • Shock wave–boundary-layer interactions (SBLIs) occur when a shock wave and a boundary layer converge and, since both can be found in almost every supersonic flow, these interactions are commonplace. The most obvious way for them to arise is for an externally generated shock wave to impinge onto a surface on which there is a boundary layer.
