Outside India, Yoga has become mainly related with the practice of asanas of Hatha Yoga, although it has influenced the whole dharmic religions family and other spiritual practices throughout the world

Biography is a type of literature and further forms of media such as film, based on the written accounts of individual lives. While a biography may focus on a subject of fiction or non-fiction, the term is frequently in reference to non-fiction. Pat Shipman however, says "I think a good biographer has to write fiction some of the time to make apparent a significant event in someone's life." This is sometimes debated. As opposed to a profile or curriculum vitae, a biography develops a complex analysis of personality, highlighting different aspects of it and including intimate details of experiences. A biography is more than a list of distant facts like birth, education, work, relationships and death. It also delves into the emotions of experiencing such events.

Ancient Greeks developed the biographical tradition which we have inherited, although until the 5th century AD, when the word 'biographia' first appears, in Damascius' Life of Isodorus, biographical pieces were called simply "lives". It is quite likely that the Greeks were drawing on a pre-existing eastern tradition; certainly Herodotus' Histories contains more exhaustive biographical information on Persian kings and subjects than on anyone else, implying he had a Persian source for it.

Geography is the study of the earth and its features and of the circulation of life on the Earth. A literal transformation would be "to describe the Earth". The first person to use the word "geography" was Eratosthenes (275-195 B.C.). Four historical civilization in geographical research are the spatial analysis of natural and human phenomena, area studies, study of man-land relationship, and investigate in earth sciences. Nonetheless, modern geography is an all-inclusive discipline that foremost seeks to understand the world and all of its human and natural complexities-- not merely where things are, but how they have changed and come to be. It is said to be the "mother of all math" and "the synthesizer of information." Geography is mainly divided into two main branches - human geography and physical geography.

conventionally, geography as well as geographers has been viewed as the same as cartography and people who study place names. Although many geographers are capable in toponymy and cartography, this is not their main preoccupation. Geographers study the spatial and temporal allotment of phenomena, processes and feature as well as the interaction of humans and their environment. As space and place persuade a variety of topics such as economics, health, climate, plants and animals, geography is highly interdisciplinary.

The talker is a kind of chat system that was originally based on MUDs. Talkers start with a virtual world in which people log in remotely (usually via telnet), that has a basic text interface with which to communicate with each other, in a similar way to how MUDs work, but without the games. Some talkers have added simple games, some even almost as detailed as the games that exist in MUDs.
talk was a program originally used for live text communication between different users of a single multi-user computer running the Unix operating system. talk eventually accommodated digital conversations between users on different machines as well. Follow-ons to talk included ntalk and ytalk. ytalk was the first to allow conversations between more than two users. All of these programs split the interface into different sections for each participant. The interfaces did not convey the order in which statements typed by different participants would be reassembled into a log of the conversation. Also, all three programs transmitted each character as it was typed, lending a more immediate feel to the discussion than recent instant messaging clients or IRC. Users more familiar with other forms of instant text communication would sometimes find themselves in embarrassing situations by typing something and deciding to withdraw the statement, unaware that the other user(s) had seen it all happen in real time.
A popular program called "flash", which sent malformed information via the talk protocol, was frequently used by pranksters to corrupt the terminal output of the unlucky target in the early 1990s. It did this by including terminal commands in the field normally designated for providing the name of the person making the request. When the victim would receive the talk request, the name of the person sending the request would be displayed on their screen. This would cause the terminal commands to execute, rendering the person's display unreadable until they reset it. Later versions of talk blocked "flash" attempts and alerted the user that one had taken place.
