Dynamism is a concept that has several meanings. One is a concept pertaining to objects and the material world. The other is a social culture philosophy. the specific meanings can be found below. Dynamism - Metaphysics. Dynamism is term of philosophy and science coined by Gottfried Leibniz (1646—1716) and developed into a full system of cosmology. The Dynamism idea in metaphysical cosmology explains the material world in terms of active, pointlike forces, with no extension but with action at ...

Magnet - Permanent magnets. All normal matter is composed of particles (protons, neutrons, and electrons), and all of these particles have the fundamental property of quantum mechanical spin. Spin gives each one of these particles an associated magnetic field. Because of this, and the fact that the average microscopic piece of matter contains huge numbers of these particles, it would be expected that all matter would be magneti ...

The simplest type of electromagnet is a coiled piece of wire. A coil forming the shape of a straight tube (similar to a corkscrew) is called a solenoid; a solenoid that is bent so that the ends meet is a toroid. Much stronger magnetic fields can be produced if a "core" of paramagnetic or ferromagnetic material (commonly iron) is placed inside the coil. The field produced by the coil causes the iron to magnetize and generate a field of its own. This field can be hundreds or thousands o ...

Nature - Metaphysics. In philosophy, the view that the material world of atoms, animals, gravity, stars, wind, microbes, etc., actually exist independently of our observations of them is termed realism; the opposing view is called idealism. Nature - The natural and the artificial. A distinction is often drawn between the "natural" and the "artificial" (="man-made"). Can such a distinction be justified? One approach is to exclude mind from the realm of the natural; another is to ...

Magnet - Permanent magnets and dipoles. All magnets are dipoles: that is, all magnets have a north and a south pole. The poles are not a pair of things on or inside the magnet. They are a concept used to discuss and describe magnets. In the image at the top of this page, the poles look like specific locations (because the highest surface intensity of the field occurs at the poles), ...

Permanent magnets can be demagnetized in the following ways: Heat. Heating a magnet past its Curie point will destroy the long range ordering. Contact. Stroking one magnet with another in random fashion will demagnetize the magnet being stroked, in some cases; some materials have a very high coercive field and cannot be demagnetized with other permanent magnets. Hammering or jarring. Such activity will destroy the long range ordering within the magnet. Being placed in a solenoid which has an alternatin ...

Electromagnets are used in many situations where a rapidly or easily variable magnetic field is desired. Many of these applications involve deflection of charged particle beams; the cathode ray tube and mass spectrometer fall into this category. Other devices cause electromagnetic fields to interact with fields from permanent magnets and produce forces. Electromagnetic actuators take advantage of the fact that, if the core of a solenoid is displaced toward one end of the coil, a force will occur tending to push the core farther in tha ...

The main advantage of an electromagnet over a permanent magnet is that the magnetic field can be rapidly manipulated over a wide range by controlling the electric current. A disadvantage is that if an electromagnet with a ferromagnetic core is turned on and off again, the core retains some residual magnetization due to hysteresis. This magnetic field can persist indefinitely. As more electricity is passed through the electromagnet ...

Strength of materials - Stress terms. Stress is the internal distribution of forces within a body that balances and reacts to the loads applied to it. It is a complicated tensor quantity that can be broken down into simpler elements for engineering purposes; Compressive stress (or compression) is the stress state when the material tends to compact (volume decrease). A simple case of compression is the uniaxial compression induced by the action of opposite, pushing forces. Most materials ...

Ultimate strength is an attribute directly related to a material, rather than just specific specimen of the material, and as such is quoted force per unit of cross section area (N / m2). For example, Ultimate Tensile Strength (UTS) of mild steel is 470MegaN / m2. It is useful to remember that 1P< ...

Developers of McMansions intend each house to look different. However, this individuality is sometimes seen as superficial, as the exteriors draw on a limited range of features (often taken from traditional styles of architecture) and the interiors share many similar features. McMansion - Size and materials. The foremost characteristic of a McMansion is the impression of size. As a consequence, these houses often appear too large for their lots. Developers are keen not to increase the ...

According to Marxist theorists, history develops in accordance with the following observations: Social progress is driven by progress in the material, productive forces a society has at its disposal (technology, labor, capital goods, etc.) Humans are inevitably involved in production relations (roughly speaking, economic relationships or institutions), which constitute our most decisive social relations. Production relations progress, with a degree of inevitability, following and corresponding to the developmen ...

The main serious objection advanced by the critics of Marxism and of historical materialism is that as soon as Marxists really begin to study the historical facts, there is either no longer anything distinctively "Marxist" about what they do, or else the facts are twisted to fit with a preconceived dogma. In the worst case, this arguably leads to the totalitarian temptation to try and force the course of history in a particular direction, based on a false belief that one "knows" the way history is moving. The idea here i ...

Most neuroscientists believe in the identity of mind and brain, a position that may be considered related to materialism and physicalism, though there is a subtle difference; namely, that postulating an identity between mind and brain (or more specifically, particular types of neuronal interactions) does not necessarily imply that mental events are 'nothing more' than physical events, but rather is more akin to saying that physical events and mental events are different aspects of a more fundamental mental-physical substratum which can be per ...

If the mind is not seen as a "mysterious" substance, and it is assumed there are only mental events and that "the mind" is no more than a series of mental events, then it is possible to inquire about the relation between mind and body in terms of the relation between mental events and physical events. One can ask: are mental events completely different from physical events, so that you can't explain what mental events are in terms of physical events; or are mental events somehow explainable as being identical with certain physi ...

The owners of houses in tracts of McMansions are typically bound by a great number of restrictive covenants, which are contractual restrictions upon acceptable uses of the property. These agreements are intended to promote aesthetic cohesiveness in the neighborhood and to maintain property values by banning certain activities defined as aesthetically dissonant or which are associated with lower socioeconomic classes. Typical clauses forbid the use of clotheslines in back yards and performing mechanical work on automobiles in the driveway; re ...

Many aspects of the McMansion have been criticised: the quality of the architecture, the quality of the construction, the wastefulness of McMansion developments, and their destruction of nature. It is ironic that McMansions are criticized for these things: arguably, although a McMansion seeks to promote its owner's wealth, prestige and good taste, those qualities are denied by the reality of bad architecture, cheap construction, small lots and tract-style development. < ...

The McMansion phenomenon has begun to spread beyond the United States into other western countries, particularly Canada and Australia. In Australia, such houses have started to appear since the 1990s, in outer suburbs of Sydney and Melbourne, often fuelled by new freeway projects (such as the M2 in the Hills region of Sydney). These are generally in the form of tract housing (by companies such as "Homeworld") and are often within their own gated communities. They have come under considerable criticism lately. The term can also (though ...
