Onion routing is a technique for anonymous communication over a computer network. Messages are repeatedly encrypted and then sent through several network nodes called onion routers. Each onion router removes a layer of encryption to uncover routing instructions, and sends the message to the next router where this is repeated. This prevents these intermediary nodes from knowing the origin, destination, and contents of the message. Onion routing was developed by Michael G. Reed, Paul F. Syverson, and David M. Goldschlag, and patented by the United States Navy in US Patent No. 6266704 (1998). As of 2009[update], Tor is the predominant technology that employs onion routing. Englisch.

The Nagant M1895 Revolver was a seven-shot, gas-seal revolver designed and produced by Belgian industrialist Léon Nagant for Tsarist Russia. The Nagant M1895 was chambered for a proprietary cartridge, 7.62x38R, and featured an unusual 'gas-seal' system in which the cylinder moved forward when the gun was cocked to close the gap between the cylinder and the barrel, providing a boost to the muzzle velocity of the fired projectile. Other Nagant revolver designs were also adopted by police and military services of Sweden (7.5 mm M1887), Norway (M1893), Poland, and Greece. Englisch.

The Willys MB US Army Jeep, along with the nearly identical Ford GPW, was manufactured from 1941 to 1945. They are considered the iconic World War II Jeep. Over the years, the World War II Jeep later evolved into 'CJ' civilian jeep and has been recognized as a symbol of rugged individualism in twentieth century American History. During World War I there were limited attempts to mechanize military forces. The US Army had already used 4x4 trucks supplied by the Four Wheel Drive Auto Co. (FWD). By the time of World War II, the United States Department of War was still seeking a light, cross-country reconnaissance vehicle. Englisch.

In physics, a virtual particle is a particle that exists for a limited time and space, introducing uncertainty in their energy and momentum due to the Heisenberg Uncertainty Principle. (Indeed, because energy and momentum in quantum mechanics are time and space derivative operators, then due to Fourier transforms their spans are inversely proportional to time duration and position spans, respectively). Virtual particles exhibit some of the phenomena that real particles do, such as obedience to the conservation laws. If a single particle is detected, then the consequences of its existence are prolonged to such a degree that it cannot be virtual. Virtual particles are viewed as the quanta that describe fields of the basic force interactions, which cannot be described in terms of real particles. Examples of these are static force fields, such as a simple electric or magnetic field, or any field that exists without excitations that result in its carrying information from place to place. Virtual particles should not be confused with antiparticles or virtual antiparticles. 92 pp. Englisch.
