Social networks and the internet shrink our understanding of the world. Argue your position on this statement - Essay Example One of the first people who recognized the value of the global connection was Marshall McLuhan, however, he is considered to be the successor of Nicolas Tesla. The last described the world in which we live today precisely- our devices that are portable and with the help of which we not only hear people but can see them any time on any distance (McLuhan 2011).McLuhan predicted that the world will transform into a Global Village in the beginning of the 20th century. The author was speaking about radio but now the term is logically applicable to World Wide Web as it helped to forget about physical distance, time obstacles, and social prejudices. Media has become a nervous system of the planet which has integrated the world really fast. With a click of a mouse a person can find a community of people with similar interests and tastes and join it. Moreover, any event can be broadcast online to the real public. That is why it is possible to talk about world community that reminds Global Vil lage where everyone knows each other. Eventually, such changes can lead to creation of new phenomenon in sociology and culture as the density of the contacts also increases (McLuhan, 1987). World Wide Web has substantially increased the speed of news spread globally: any event in one part of the world becomes known to the Internet users in a second. However, this global involvement into world problems has also increased the responsibility. According to McLuhan, the enhanced "electric speed in bringing all social and political functions together in a sudden implosion has heightened human awareness of responsibility to an intense degree"Â  (McLuhan, 1964). Another discovery of McLuhan was the fact the type of media influences the information and becomes a message itself. So Internet can be regarded as a message as it changes completely the way people understand and perceive things, and the main issue of this message is its speed (McLuhan, 1962). So

Bar built estuaries - Essay Example An example for this is the East Matagorda Bay. Bar-built estuaries are also found in The Netherlands. Estuaries found in North Carolina are also the examples of bar-built estuaries; for example Albemarle Sound and Pamlico Sound. Bar-built estuaries are semi-isolated from ocean waters through the barrier beaches found between estuaries and oceans. Barrier spits and barrier islands are located between estuaries and oceans. As barrier beaches get formed they partially encircle the estuary allowing only small inlets to allow contacts between estuaries and ocean waters. Bar-built estuaries usually get formed over gently sloping plains placed along tectonically stable boundaries of marginal sea coasts and continents. The barrier beaches that encircle bar-built estuaries are formed in numerous ways. Wave action causes the formation of offshore bars. Here, the sand from the seafloor gets accumulated in extended bars parallel to the shoreline. This forms barrier beaches. Reformation of sediment discharge from rivers through current, wave, and wind action causes the formation of barrier beaches. Mainland beach ridges get engulfed because of the rise in sea level. This led to the breaking of the ridges and flooding of the coastal lowlands. Shallow lagoons get formed as a result. This contributes to the formation of barrier beaches. Extension of barrier spits through the erosion of headlands also form barrier beaches. Barrier beaches get created in shallow water. They are mostly parallel to the shoreline. This leads to the formation of long narrow estuaries. Water depth of these estuaries is between 5 m and 10 m. Barnegat Bay, New Jersey, Pamlico Sound, North Carolina and Laguna Madre, Texas are some of the examples of bar-built estuaries. Scientists have made use of variety of criteria to classify estuaries. Previously they used to classify estuaries based on the rate of fresh water, evaporation.
