That branch of applied physics which deals with the motion of projectiles and the conditions governing that motion. Commonly called the science of shooting, it is, for practical purposes, subdivided into exterior and interior ballistics.
Industry:Science
The determination of the location of the interface between two fluids, separable by gravity, with respect to a fixed horizontal datum plane. The respective fluids may be any fluids, liquid or gaseous, which do not mix and have specific gravities significantly different from one another. Fluids include granular or particulate solids which are fluidized or handled like fluids. The most common level measurements are, however, between a liquid and a gas or vapour.
Industry:Science
The growth, development, or other responses of organisms to the length of night or day or both. Photoperiodism has been observed in plants and animals, but not in bacteria (prokaryotic organisms), other single-celled organisms, or fungi.
Industry:Science
The expression perpetual motion, or perpetuum mobile, arose historically in connection with the quest for a mechanism which, once set in motion, would continue to do useful work without an external source of energy or which would produce more energy than it absorbed in a cycle of operation. This type of motion, now called perpetual motion of the first kind, involves only one of the three distinct concepts presently associated with the idea of perpetual motion.
Industry:Science
The generic name for the intensely green, blue, or purple tetrapyrrolic pigments found in higher plants, algae, and photosynthetic bacteria that serve as photoreceptors and transducers of light energy to chemical energy in photosynthesis.
Industry:Science
The inheritance of a trait (phenotype) that is determined by a gene located on one of the sex chromosomes. These traits, including many diseases, have characteristic patterns of familial transmission; for a century these patterns were used to localize the genes for these traits to a specific chromosome. As the genomes of many organisms have now been completely sequenced, reliance on the specific pattern of inheritance to map genes on sex chromosomes has waned.
Industry:Science
The haphazard complexity of a crumpled sheet or membrane has recently been shown to be governed by a simple mathematical law. Other things being equal, an eightfold increase in the size of a sheet implies a twofold increase in its energy.
Industry:Science
The detailed study of the anatomy of a part or region of the body of an animal, most commonly applied to regional human anatomy. This is in contrast, but supplementary, to the study of organ systems, such as the cardiovascular, where all the structures pertaining to the system are studied in their continuity. To obtain the maximum information about the anatomy of an animal, both methods are used, as well as histological, embryological, and functional studies.
Industry:Science
That branch of physics which deals with the influence of a magnetic field on optical phenomena. Considering the fact that light is electromagnetic radiation, an interaction between light and a magnetic field would seem quite plausible. It is, however, not the direct interaction of the magnetic field and light that produces the known magnetooptic effects, but the influence of the magnetic field upon matter which is in the process of emitting or absorbing light.
