Where "THESE NAMES" come from

Apple Computers
It was the favourite fruit of founder Steve Jobs. He was three months late in filing a name for the business, and he threatened to call his company Apple Computers if the other colleagues didn't suggest a better name by 5 O'clock.

It is not an acronym as popularly believed. It is short for San Francisco.

This name was formed by using COMp, for computer, and PAQ to denote a small integral object.

The name was derived from the founder's name Dr.Michael Cowpland. It stands for COwpland REsearch Laboratory.

The name started as a joke boasting about the amount of information the search-engine would be able to search. It was originally named 'Googol', a word for the number represented by 1 followed by 100 zeros.After founders - Stanford graduate students Sergey Brin and Larry Page presented their project to an angel investor, they received a cheque made out to 'Google'

Founder Jack Smith got the idea of accessing e-mail via the web from a computer anywhere in the world.When Sabeer Bhatia came up with the business plan for the mail service, he tried all kinds of names ending in 'mail' and finally settled for hotmail as it included the letters "html" - the programming language used to write web pages. It was initially referred to as HoTMaiL with selective uppercasing.

Hewlett Packard
Bill Hewlett and Dave Packard tossed a coin to decide whether the company they founded would be called Hewlett-Packard or Packard-Hewlett.

Bob Noyce and Gordon Moore wanted to name their new company 'Moore Noyce' but that was already trademarked by a hotel chain so they had to settle for an acronym of INTegrated ELectronics.

Lotus (Notes)
Mitch Kapor got the name for his company from 'The Lotus Position' or 'Padmasana'. Kapor used to be a teacher of Transcendental Meditation of Maharishi Mahesh Yogi.

Coined by Bill Gates to represent the company that was devoted to MICROcomputer SOFTware. Originally christened Micro-Soft, the '-' was removed later on.

Founder Paul Galvin came up with this name when his company started manufacturing radios for cars. The popular radio company at the time was called Victrola.

Larry Ellison and Bob Oats were working on a consulting project for the CIA (Central Intelligence Agency). The code name for the project was called Oracle (the CIA saw this as the system to give answers to all questions or something such). The project was designed to help use the newly written SQL code by IBM. The project eventually was terminated but Larry and Bob decided to finish what they started and bring it to the world. They kept the name Oracle and created the RDBMS engine. Later they kept the same name for the company.

It originated from the Latin word 'sonus' meaning sound, and 'sonny' a slang used by Americans to refer to a bright youngster.

Founded by 4 Stanford University buddies, SUN is the acronym for Stanford University Network. Andreas Bechtolsheim built a microcomputer; Vinod Khosla recruited him and Scott McNealy to manufacture computers based on it, and Bill Joy to develop a UNIX-based OS for the computer.

The word was invented by Jonathan Swift and used in his book 'Gulliver's Travels'. It represents a person who is repulsive in appearance and action and is barely human. Yahoo! Founders Jerry Yang and David Filo selected the name because they considered themselves yahoos[DOUBLEPOST=1359254012][/DOUBLEPOST]

Introduction to study branches!

Social Science

Any discipline or branch of science that deals with the sociocultural aspects of human behaviour.

The social sciences generally include
cultural anthropology, economics, political science, sociology, criminology, and social psychology. Comparative law and comparative religion (the comparative study of the legal systems and religions of different nations and cultures) are also sometimes regarded as social sciences.

Political Science

Academic discipline concerned with the empirical study of government and politics.

Political scientists have investigated the nature of states, the functions performed by governments, voter behaviour, political parties, political culture,
political economy, and public opinion, among other topics. Though it has roots in the political philosophies of Plato and Aristotle, political science in the modern sense did not begin until the 19th century, when many of the social sciences were established. Its empirical and generally scientific orientation is traceable to the work of Henri de Saint-Simon and Auguste Comte. The first institution dedicated to its study, the Free School of Political Science, was founded in Paris in 1871.


Social science that analyzes and describes the consequences of choices made concerning scarce productive resources.

Economics is the study of how individuals and societies choose to employ those resources: what goods and services will be produced, how they will be produced, and how they will be distributed among the members of society. Economics is customarily divided into
microeconomics and macroeconomics. Of major concern to macroeconomists are the rate of economic growth, the inflation rate, and the rate of unemployment. Specialized areas of economic investigation attempt to answer questions on a variety of economic activity; they include agricultural economics, economic development, economic history, environmental economics, industrial organization, international trade, labour economics, money supply and banking, public finance, urban economics, and welfare economics. Specialists in mathematical economics and econometrics provide tools used by all economists. The areas of investigation in economics overlap with many other disciplines, notably history, mathematics, political science, and sociology.

Cultural anthropology

Branch of anthropology that deals with the study of culture.

The discipline uses the methods, concepts, and data of
archaeology, ethnography, folklore, linguistics, and related fields in its descriptions and analyses of the diverse peoples of the world. Called social anthropology in Britain, its field of research was until the mid 20th century largely restricted to the small-scale (or "primitive"), non-Western societies that first began to be identified during the age of discovery. Today the field extends to all forms of human association, from village communities to corporate cultures to urban gangs. Two key perspectives used are those of holism (understanding society as a complex, interactive whole) and cultural relativism (the appreciation of cultural phenomena within their own context). Areas of study traditionally include social structure, law, politics, religion, magic, art, and technology.


Science of society, social institutions, and social relationships, and specifically the systematic study of the development, structure, interaction, and collective behaviour of organized human groups.

It emerged at the end of the 19th century through the work of
Émile Durkheim in France, Max Weber and Georg Simmel in Germany, and Robert E. Park and Albion Small in the U.S. Sociologists use observational techniques, surveys and interviews, statistical analysis, controlled experiments, and other methods to study subjects such as the family, ethnic relations, schooling, social status and class, bureaucracy, religious movements, deviance, the elderly, and social change.


Scientific study of nonlegal aspects of crime, including its causes and prevention.

Criminology originated in the 18th century when social reformers began to question the use of punishment for retribution rather than deterrence and reform. In the 19th century, scientific methods began to be applied to the study of crime. Today criminologists commonly use
statistics, case histories, official records, and sociological field methods to study criminals and criminal activity, including the rates and kinds of crime within geographic areas. Their findings are used by lawyers, judges, probation officers, law-enforcement and prison officials, legislators, and scholars to better understand criminals and the effects of treatment and prevention. See also delinquency, penology.

Social Psychology

Branch of psychology concerned with the personality, attitudes, motivations, and behaviour of the individual or group in the context of social interaction.

The field emerged in the U.S. in the 1920s. Topics include the attribution of
