Define anti-aliasing
What do you understand by the term anti-aliasing? Describe briefly?
Expert
Anti-aliasing is a technique for enhancing the realism of an image by eliminating the jagged edges from it. Such jagged edges or jaggies appear as a computer monitor has square pixels, and such square pixels are inadequate for exhibiting lines or curves which are not parallel to the pixels and other reason is low sampling rate of the image information, which in turn leads to such jaggies.
Superconductivity: The phenomenon by which, at adequately low temperatures, a conductor can conduct the charge with zero (0) resistance. The current theory for describing superconductivity is the BCS theory.
Rayleigh-Jeans law: For a blackbody at the thermodynamic temperature T, the radiance R over a range of frequencies between the nu and nu + dnu is specified by: R = 2 pi nu2 k T/c2.<
Noether theorem (Noether): A theorem that explains that symmetries are what gives rise to conserved quantities. For example, the translational symmetry (that is the fact that the laws of physics work the same in all positions) gives r
Tau-theta paradox (1950s): Whenever two distinct kinds of kaons, tau and theta (nowadays tau refers to a totally different particle) decay, tau decays into three particles, whereas the theta decays into two. The tau and theta vary onl
