The boiling point of a liquid is the temperature at which the liquid and vapor phases are in equilibrium with each other at a specified pressure. Therefore, the boiling point is the temperature at which the vapor pressure of the liquid is equal to the applied pressure on the liquid. The boiling point at a pressure of 1 atmosphere is called the normal boiling point.
Industry:Science
That branch of mathematics which deals with solutions of systems of linear equations and the related geometric notions of vector spaces and linear transformations. It is fundamental in the theory of the calculus of functions of several variables and hence is of great importance in the application of mathematics to physical and biological sciences, economics, and so on.
Industry:Science
The field of physics that studies the interaction of electromagnetic radiation with electrically charged matter within the framework of relativity and quantum mechanics. It is the fundamental theory underlying all disciplines of science concerned with electromagnetism, such as atomic physics, chemistry, biology, the theory of bulk matter, and electromagnetic radiation.
Industry:Science
The harvestmen or daddy longlegs, an order of the class Arachnida; sometimes known as Phalangida. About 4500 species are known. They are common in temperate and tropical climates. Most are red, brown, or black and 5–20 mm (0.2–0.8 in.) long, although a few are only 1–2 mm (0.04–0.08 in.). Some large tropical species have bright iridescent colors and elaborate spines.
Industry:Science
The generally accepted system of naming plants. The study of plant variation and kinds leads to classification—the grouping of individual plants, the grouping of the groups, and the organizing of the groups (taxa) into ranks. Nomenclature deals with the naming of the taxa, the goal being to establish one correct scientific name for a given taxon with a given definition.
Industry:Science
The behavior of an electrical device or communications system whose output is not identical in form to the input signal. In a distortionless communications system, freedom from distortion implies that the output must be proportional to a delayed version of the input, requiring a constant-amplitude response and a phase characteristic that is a linear function of frequency.
Industry:Science
The branch of optics which treats of light (or electromagnetic radiation in general) with explicit recognition of its wave nature. The counterpart to wave optics is ray optics or geometrical optics, which does not assume any wave character but treats the propagation of light as a straight-line phenomenon except for changes of direction induced by reflection or refraction.
Industry:Science
The engineering discipline concerned with the machinery and systems of ships and other marine vehicles and structures. Marine engineers are responsible for the design and selection of equipment and systems, for installation and commissioning, for operation, and for maintenance and repair. They must interface with naval architects, especially during design and construction.
Industry:Science
The formation of an embryo from a fertilized ovum, or zygote. Development begins when the zygote, originating from the fusion of male and female gametes, enters a period of cellular proliferation, or cleavage. Cells of the embryo subsequently give rise to the tissues and organs of the body in a temporal and spatial pattern that creates a functional, multicellular organism.
Industry:Science
That point of a material object or a system of objects that moves as if all the external forces were acting on the entire mass of the object or the system of objects concentrated at that point. The motion of a material object or a system of objects can be described in terms of the translational motion of the center of mass and the rotational motion about the center of mass.
