ARTIFICIAL INTELLIGENCE

Artificial intelligence (AI) is both the intelligence of machines and the branch of computer science which aims to create it.

Major AI textbooks define artificial intelligence as “the study and design of intelligent agents,” where an intelligent agent is a system that perceives its environment and takes actions which maximize its chances of success. AI can be seen as a realization of an abstract intelligent agent (AIA) which exhibits the functional essence of intelligence. John McCarthy, who coined the term in 1956, defines it as “the science and engineering of making intelligent machines.”

Among the traits that researchers hope machines will exhibit are reasoning, knowledge, planning, learning, communication, perception and the ability to move and manipulate objects. General intelligence (or “strong AI”) has not yet been achieved and is a long-term goal of AI research.

AI research uses tools and insights from many fields, including computer science, psychology, philosophy, neuroscience, cognitive science, linguistics, ontology, operations research, economics, control theory, probability, optimization and logic. AI research also overlaps with tasks such as robotics, control systems, scheduling, data mining, logistics, speech recognition, facial recognition and many others. Other names for the field have been proposed, such as computational intelligence, synthetic intelligence, intelligent systems, or computational rationality

MOUNT EVEREST

The Great Trigonometric Survey of India established the first published height of Everest in 1856 at 29,002 ft (8,840 m), although at the time Everest was known as Peak XV. The mountain was given its official English name in 1865 by the Royal Geographical Society upon recommendation of Andrew Waugh, the British Survey General of India at the time. Waugh was unable to propose an established local name due to Nepal and Tibet being closed to foreigners at the time although Chomolungma had been in common use by Tibetans for centuries.

By the end of the 2007 climbing season, there had been 3,679 ascents to the summit by 2,436 individuals. There have been 210 deaths on the mountain, where conditions are so difficult that most corpses have been left where they fell; some are visible from standard climbing routes. Climbers range from experienced mountaineers to relative novices who count on their paid guides to get them to the top. This means climbers are a significant source of tourist revenue for Nepal, whose government also requires all prospective climbers to obtain an expensive permit, costing up to $25,000 (USD) per person.
