History Of Google ... A small search engine called "RankDex" from IDD Information Services (a subsidiary of Dow Jones) designed by Robin Li was, since 1996, already exploring a similar strategy for site-scoring and page ranking. The technology in RankDex would be patented and used later when Li founded Baidu in China...
Photography ... Photography has many uses for business, science, manufacturing (e.g. photolithography), art, and recreational purposes...
Sharia ... There are two primary sources of Islamic law: the precepts set forth in the Quran, and the example set by the Islamic prophet Muhammad in the Sunnah. Where it has official status, sharia is interpreted by Islamic judges (qadis) with varying responsibilities for the religious leaders (imams)...
Wireless Telegraphy ... Wireless telegraphy originated as a term to describe electrical signaling without the electric wires to connect the end points. The intent was to distinguish it from the conventional electric telegraph signaling of the day that required wire connection between the end points...
Computational Creativity ... The goal of computational creativity is to model, simulate or replicate creativity using a computer, to achieve one of several ends: to construct a program or computer capable of human-level creativity to better understand human creativity and to formulate an algorithmic perspective on creative behavior in humans to design programs that can enhance human creativity without necessarily being creative themselves The field of computational creativity concerns itself with theoretical and practical issues in the study of creativity. Theoretical work on the nature and proper definition of creativity is performed in parallel with practical work on the implementation of systems that exhibit creativity, with one strand of work informing the other...
Television Network ... Within the industry, a tiering is sometimes created among groups of networks based on whether their programming is simultaneously originated from a central point, and whether the network master control has the technical and administrative capability to take-over the programming of their affiliates in real-time when it deems this necessary — the most common example being national breaking news events...
Movie Camera ... On June 21 1889, William Fries-Greener was issued patent no. 10131 for his 'chronophotographic' camera...
News ... The first documented use of an organized courier service for the diffusion of written documents is in Egypt, where Pharaohs used couriers for the diffusion of their decrees in the territory of the State (2400 BC). This practice almost certainly has roots in the much older practice of oral messaging and may have been built on a pre-existing infrastructure...
Network Science ... In the 1930s Jacob Moreno, a psychologist in the Gestalt tradition, arrived in the United States. He developed the sociogram and presented it to the public in April 1933 at a convention of medical scholars...
Google ... Google was first incorporated as a privately held company on September 4, 1998, and its initial public offering followed on August 19, 2004. At that time Larry Page, Sergey Brin, and Eric Schmidt agreed to work together at Google for 20 years, until the year 2024...
Biotechnology ... For thousands of years, humans have used selective breeding to improve production of crops and livestock to use them for food. In selective breeding, organisms with desirable characteristics are mated to produce offspring with the same characteristics...
Epidemiology ... The distinction between 'epidemic' and 'endemic' was first drawn by Hippocrates, to distinguish between diseases that are 'visited upon' a population (epidemic) from those that 'reside within' a population (endemic). The term 'epidemiology' appears to have first been used to describe the study of epidemics in 1802 by the Spanish physician Villalba in Epidemiología Española...
Mobile Phone Features ... The common components found on all phones are: A battery, providing the power source for the phone functions. An input mechanism to allow the user to interact with the phone...
Stochastic Process ... In the simplest possible case (discrete time), a stochastic process amounts to a sequence of random variables known as a time series (for example, see Markov chain). Another basic type of a stochastic process is a random field, whose domain is a region of space, in other words, a random function whose arguments are drawn from a range of continuously changing values...
Blog ... The emergence and growth of blogs in the late 1990s coincided with the advent of web publishing tools that facilitated the posting of content by non-technical users. (Previously a knowledge of such technologies as HTML and FTP had been required to publish content on the Web.) Although not a must, most good quality blogs are interactive, allowing visitors to leave comments and even message each other via GUI widgets on the blogs and it is this interactivity that distinguishes them from other static websites...
Google Search ... The order of search results on Google's search-results pages is based, in part, on a priority rank called a "PageRank". Google Search provides many options for customized search, using Boolean operators such as: implied "AND" (if several concatenated search terms separated by spaces are given, only pages containing all of them should be returned), exclusion ("-xx"), alternatives ("xx OR yy"), and wildcard ("x * x")...
History Of Radio ... Nikola Tesla experimentally demonstrated the transmission and radiation of radio frequency energy in 1892 and 1893 proposing that it might be used for the telecommunication of information. The Tesla method was described in New York in 1897...
Police State ... The inhabitants of a police state experience restrictions on their mobility, and on their freedom to express or communicate political or other views, which are subject to police monitoring or enforcement. Political control may be exerted by means of a secret police force which operates outside the boundaries normally imposed by a constitutional state...
Mobile Phone ... In addition to telephony, modern mobile phones also support a wide variety of other services such as text messaging, MMS, email, Internet access, short-range wireless communications (infrared, Bluetooth), business applications, gaming and photography. Mobile phones that offer these and more general computing capabilities are referred to as smartphones...
Newspaper ... A wide variety of material has been published in newspapers, including editorial opinions, criticism, persuasion and op-eds; obituaries; entertainment features such as crosswords, sudoku and horoscopes; weather news and forecasts; advice, food and other columns; reviews of radio, movies, television, plays and restaurants; classified ads; display ads, radio and television listings, inserts from local merchants, editorial cartoons, gag cartoons and comic strips... History Gazettes and bulletins In China, early government-produced news sheets, called tipao, circulated among court officials during the late Han dynasty (second and third centuries AD)...
History Of Nanotechnology ... After Feynman's death, scholars studying the historical development of nanotechnology have concluded that his actual role in catalyzing nanotechnology research was limited, based on recollections from many of the people active in the nascent field in the 1980s and 1990s. Chris Toumey, a cultural anthropologist at the University of South Carolina, found that the published versions of Feynman’s talk had a negligible influence in the twenty years after it was first published, as measured by citations in the scientific literature, and not much more influence in the decade after the Scanning Tunneling Microscope was invented in 1981...
Digital Photography ... Until the advent of such technology, photographs were made by exposing light sensitive photographic film, and used chemical photographic processing to develop and stabilize the image. By contrast, digital photographs can be displayed, printed, stored, manipulated, transmitted, and archived using digital and computer techniques, without chemical processing...
