Tunnel
A tunnel is an underground passageway, dug through surrounding soil, earth or rock, and enclosed except for the entrance and exit, commonly at each end. A pipeline is not a tunnel, though some recent tunnels have used immersed tube construction techniques rather than traditional tunnel boring methods. A tunnel may be for foot or vehicular road traffic, for rail traffic, or for a canal. The central portions of a rapid transit network are usually in the tunnel. Some tunnels are used as sewers or aqueducts to supply water for consumption or for hydroelectric stations. Utility tunnels are used for routing steam, chilled water, electrical power or telecommunication cables, as well as connecting buildings for convenient passage of people and equipment. Secret tunnels are built for military purposes, or by civilians for smuggling of weapons, contraband, or people. Special tunnels, such as wildlife crossings, are built to allow wildlife to cross human-made barriers safely. ...

Hobby Tunneling
Hobby tunneling is tunnel construction as a diversion. Usually, hobby tunnelers dig their tunnels by hand, using little equipment, and some can spend years or even decades to achieve any degree of completion. In some cases tunnels have been dug secretly, and only discovered by chance. Motivations A tunnel is an underground passageway, dug through the surrounding soil or rock for the purpose of transport, passage or communication. Tunnel construction is a sub-discipline of civil engineering and usually the domain of engineers and construction companies. When civilians dig tunnels it may be for criminal purposes, like smuggling or hiding illegal goods, or gaining unauthorised access to an area. People may also build escape tunnels, such as those under the Berlin Wall. Tunneling may be part of the building of underground dwellings. Subterranean construction may be done as an art form, as in the work of Ra Paulette. Dutch graphic designer Leanne Wijnsma digs short, shallow t ...

Quantum Tunneling
In physics, a quantum (plural quanta) is the minimum amount of any physical entity (physical property) involved in an interaction. The fundamental notion that a physical property can be "quantized" is referred to as "the hypothesis of quantization". This means that the magnitude of the physical property can take on only discrete values consisting of integer multiples of one quantum. For example, a photon is a single quantum of light (or of any other form of electromagnetic radiation). Similarly, the energy of an electron bound within an atom is quantized and can exist only in certain discrete values. (Atoms and matter in general are stable because electrons can exist only at discrete energy levels within an atom.) Quantization is one of the foundations of the much broader physics of quantum mechanics. Quantization of energy and its influence on how energy and matter interact (quantum electrodynamics) is part of the fundamental framework for understanding and describing nature. E ...

Tunneling (fraud)
Tunneling or tunnelling is financial fraud committed by "the transfer of assets and profits out of firms for the benefit of those who control them". In legal terms, this is known as a fraudulent transfer, such as when a group of major shareholders or the management of a publicly-traded company orders that company to sell off its assets to a second company at unreasonably low prices. The shareholders or management typically own the second company outright, and thus profit from the otherwise disastrous sale. Tunneling differs from outright theft because people who engage in tunneling generally comply with all of the relevant legal procedures; it is thus a subtler scheme than simply writing checks from a company to a private bank account. While people widely agree that tunneling is unethical, penalties for it vary widely; some states impose criminal sanctions, whereas other states provide either for civil suits only, or for no sanctions at all. Origin The word ''tunneling'' was pro ...

Tunneling Protocol
In computer networks, a tunneling protocol is a communication protocol which allows for the movement of data from one network to another. It involves allowing private network communications to be sent across a public network (such as the Internet) through a process called encapsulation. Because tunneling involves repackaging the traffic data into a different form, perhaps with encryption as standard, it can hide the nature of the traffic that is run through a tunnel. The tunneling protocol works by using the data portion of a packet (the payload) to carry the packets that actually provide the service. Tunneling uses a layered protocol model such as those of the OSI or TCP/IP protocol suite, but usually violates the layering when using the payload to carry a service not normally provided by the network. Typically, the delivery protocol operates at an equal or higher level in the layered model than the payload protocol. Uses A tunneling protocol may, for example, allow a foreig ...
