Lesson

A lesson is a structured period of time where learning is intended to occur. It involves one or more students (also called pupils or learners in some circumstances) being taught by a teacher or instructor. A lesson may be either one section of a textbook (which, apart from the printed page, can also include multimedia) or, more frequently, a short period of time during which learners are taught about a particular subject or taught how to perform a particular activity. Lessons are generally taught in a classroom but may instead take place in a situated learning environment.

In a wider sense, a lesson is an insight gained by a learner into previously unfamiliar subject-matter. Such a lesson can be either planned or accidental, enjoyable or painful. The colloquial phrase "to teach someone a lesson", means to punish or scold a person for a mistake they have made in order to ensure that they do not make the same mistake again.

Lessons can also be made entertaining. When the term education is combined with entertainment, the term edutainment is coined.

The Social Network

The Social Network is a 2010 American biographical drama film directed by David Fincher and written by Aaron Sorkin. Adapted from Ben Mezrich's 2009 book The Accidental Billionaires: The Founding of Facebook, A Tale of Sex, Money, Genius, and Betrayal, the film portrays the founding of social networking website Facebook and the resulting lawsuits. It stars Jesse Eisenberg as founder Mark Zuckerberg, along with Andrew Garfield as Eduardo Saverin and Justin Timberlake as Sean Parker, the other principals involved in the website's creation. Neither Zuckerberg nor any other Facebook staff were involved with the project, although Saverin was a consultant for Mezrich's book. The film was released in the United States by Columbia Pictures on October 1, 2010.

The Social Network received widespread acclaim, with critics praising its direction, screenplay, acting, editing and score. Although several people portrayed in the film criticized its historical inaccuracies, the film appeared on 78 critics' Top 10 lists for 2010; of those critics, 22 had the film in their number-one spot, the most of any film in its year. Rolling Stone's Peter Travers said "The Social Network is the movie of the year. But Fincher and Sorkin triumph by taking it further. Lacing their scathing wit with an aching sadness, they define the dark irony of the past decade." It was also Roger Ebert's selection for the best film of the year.

Social network

A social network is a social structure made up of a set of social actors (such as individuals or organizations), sets of dyadic ties, and other social interactions between actors. The social network perspective provides a set of methods for analyzing the structure of whole social entities as well as a variety of theories explaining the patterns observed in these structures. The study of these structures uses social network analysis to identify local and global patterns, locate influential entities, and examine network dynamics.

Social networks and the analysis of them is an inherently interdisciplinary academic field which emerged from social psychology, sociology, statistics, and graph theory. Georg Simmel authored early structural theories in sociology emphasizing the dynamics of triads and "web of group affiliations."Jacob Moreno is credited with developing the first sociograms in the 1930s to study interpersonal relationships. These approaches were mathematically formalized in the 1950s and theories and methods of social networks became pervasive in the social and behavioral sciences by the 1980s.Social network analysis is now one of the major paradigms in contemporary sociology, and is also employed in a number of other social and formal sciences. Together with other complex networks, it forms part of the nascent field of network science.
