It is rumored that the Air Force has been involved in the many UFO cover-ups. The first event in which the Air Force has confescated unknown material include the Roswell UFO incident. Another less known incident was the Kecksburg UFO crash. Residents of the crash site claimed to have seen a flat-bed military truck passing by at the time and then returning with an acorn-shaped object (the presumed UFO) covered in sheets. There are also some official UFO investigation groups. The Majestic 12 is an alleged secret committee of high-level ...

An electromagnetic calorimeter is one specifically designed to measure the energy of particles that interact primarily via the electromagnetism, while a hadronic calorimeter is one designed to measure particles that interact via the strong nuclear force. (See types of particle showers for the differences between the two.) Either of the above types can be made as a sampling calorimeter, in which the material that produces the particle shower is distinct from the material that measures the deposited energy. Typicall ...

Hysteresis phenomena occur in magnetic and ferromagnetic materials, as well as in the elastic and electromagnetic behavior of materials, in which a lag occurs between the application and the removal of a force or field and its subsequent effect. Electric hysteresis occurs when applying a varying electric field, and elastic hysteresis occurs in response to a varying force. If the displacement of a system with hysteresis is plotted on a graph against the applied force, the resulting curve is in the form of a loop. In contrast, the curve ...

Arch bridge - Advantage in use of simple materials. Stone and other such materials are strong in compression and somewhat so in shear, but cannot resist much force in tension so masonry arch bridges are designed to be constantly under compression. In the first compression arch bridges, a keystone in the middle of the bridge bore the weight of the rest of the bridge. The more weight that was put onto the bridge, the stronger its structure became. Masonry arch bridges use a quantity of fill (typically loose rubble) ...

In nature, there is a strong evolutionary pressure for animals to blend into their environment or conceal their shape; for prey animals to avoid predators and for predators to be able to sneak up on prey. Natural camouflage is one method that animals use to meet these aims. Different aspects of animal camouflage exist due to difference in the sensory abilities of different animals. Some animals use mimicry, seeming to be something else, such as a leaf, a stone, a twig, ...

Li: Important philosophical term of varied meaning throughout Confucian history; Early Confucian writings depict li as ceremonial formality; Neo-Confucian writers such as Chu Hsi see it as a metaphysical principal of structural form, which is in contrast with material force (ch'i).

PRANA: the yogic concept of a cosmic energy or life force, similar to the Chinese idea of chi, that enters the body with the breath. Prana is thought to flow through the body, bringing health and vitality. It is considered the vital link between the spiritual self and the material self.

Building cities in space will require materials, energy, transportation, communications, life support, and radiation protection. Space colonization - Materials. Colonies on the Moon and Mars can use local materials, although the Moon is deficient in carbon and nitrogen. For orbital colonies, launching materials from Earth is very expensive, so bulk materials should come from the Moon or Near-Earth Objects (NEOs - asteroids and comets with orbits near Earth) where gravitational forces are much less, there i ...

For more details, see Military camouflage. Camouflage was not in wide use in early warfare. 19th century armies tended to use bright colours and bold, impressive designs. These were intended to daunt the enemy, attract recruits, foster unit cohesion, allow easier identification of units in the fog of war. Smaller, irregular units of scouts in the 18th century were the first to adopt colours in drab shades of brown and green. Major armies retained their colour until convinced otherwise. The British in India in 1857 were f ...

Wright-Patterson features prominently in the accounts of the so-called Roswell UFO Incident. Supposedly, wreckage of an unidentified flying object which crashed near Roswell, New Mexico was transported to Wright-Patterson for study. Perhaps the most credible report regarding the Roswell Incident comes from retired Air Force General Arthur Exon, as related to ufologists Kevin Randle and Donald Schmitt. In 1947, Exon was stationed at Wright Patterson Air Force Base. Shortly after the reports of the saucer crash, Exon said strange material was shipped to Wright Patterson. Though very thin and lig ...

MacKay's statement above remains one of the most important elements in the theory of camouflage — an exact match with the environment's colours is less crucial than the patterning of the regions of colour themselves. Ideally, camouflage should be made to break up and thereby conceal the structural lines of the object which it hides. Thus, the patterns often seen on camouflage clothing, masking cloth and vehicle paints are carefully constructed to deceive the human eye by breaking up the boundaries that define sharp edges and human silhouettes. This is called h ...

The transfer of camouflage patterns from battle to exclusively civilian uses is a recent phenomenon. While many hundreds of artists were involved in the development of camouflage during and since WW I the disparate sympathies of the two cultures restained the use of "militaristic" forms in works other than those of war artists. Since the 1960s however artists have seized apon camouflage as a means to twist and subvert it away from its military origins and symbolism. The concept of camouflage - to c ...

Ch'i: literally "breath," important philosophical term of varied meaning throughout Chinese history; early Chinese writings see it as a physiological principle of vital energy, whereas Neo-Confucian writers such as Chu Hsi see it as a metaphysical principal of material force in contrast with structural form (li).

Chu Hsi (1130-1200): Most influential Neo-Confucian philosopher whose interpretation of Confucianism became the standard view until the 20th century; for Chu, the "investigation of things" involves knowledge of the structural form (li) of the universe, as distinct from the material force of the universt (ch'i).

Prana

The life force or energy which animates material forms. It is also present in breath. Prana can be compared to the concept of the "Breath of Life" in Genesis activating the created world and the physical being of man. Also Chi or Ki.

radiation

Power existing in various wave rates and lengths. Believed to be the carrier of spirit communication with sensitives. This force is immune to material insulation and passes through solid substances. It is not explained by physical laws and is generally accepted as being of the supernormal

Depending on the material, size and geometry of the object, and the forces applied, various types of deformation may result. Deformation - Elastic deformation. This type of deformation is reversible. Once the forces are no longer applied, the object returns to its original shape. As the name implies, elastic (rubber) has a rather large elastic deformation range. Soft thermoplastics and metals have moderate elastic deformation ranges while ceramics, crystals, and hard thermosetting pla ...
