Telecommunications

Companies, Services, Equipment, Technology, Business

Telecommunication is the technique of transmitting a message, from one point or place to another with the typical additional attribute of being bi-directional. In practice it also recognizes that something may be lost in the process; hence the term 'telecommunication' covers all forms of distance communications, including radio, telegraphy, television, telephony, data communication and computer networking.

Physics

Physics (from Greek from φυσικός (phusikos): natural, from φύσις (fysis): Nature) is the science of Nature in the broadest sense.

Physicists study the behaviour and interactions of matter and radiation. Theories of physics are generally expressed as mathematical relations. Well-established theories are often referred to as physical laws or laws of physics; however, like all scientific theories, they are ultimately provisional.
