Technology is the practical use of science, including the making, modification or improvement, applied activity or behavior, use and knowledge of tools, machines, techniques, crafts, systems, methods of organization, or environmental modifications or arrangement in order to solve a problem, improve a preexisting solution to a problem, achieve a goal or perform a specific function. It can also refer to the collection of such tools, machinery, modifications, environmental arrangement and procedures. Technologies significantly affect human as well as other animal species' ability to control and adapt to their natural environments. The word technology comes from Greek τεχνολογία (technología); from τέχνη (téchnē), meaning "art, skill, craft", and -λογία (-logía), meaning "study of-". The term can be applied either generally or to many specific areas, examples of which include construction technology, medical technology and information technology.
The human species' use of technology began with the conversion of natural resources into simple tools. The prehistorical discovery of the ability to control fire increased the available sources of food and the invention of the wheel helped humans in travelling in and controlling their environment. Recent technological developments, including the printing press, the telephone, and the Internet, have lessened physical barriers to communication and allowed humans to interact freely on a global scale. However, not all technology has been used for peaceful purposes; the development of weapons of ever-increasing destructive power has progressed throughout history, from clubs to nuclear weapons.
Technology has affected society and its surroundings in a number of ways. In many societies, technology has helped develop more advanced economies (including today's global economy) and has allowed the rise of a leisure class. Many technological processes produce unwanted by-products, known as pollution, and deplete natural resources, to the detriment of the Earth and its environment. Various implementations of technology influence the values of a society and new technology often raises new ethical questions. Examples include the rise of the notion of efficiency in terms of human productivity, a term originally applied only to machines, and the challenge of traditional norms.
Philosophical debates have arisen over the present and future use of technology in society, with disagreements over whether technology improves the human condition or worsens it. Neo-Luddism, anarcho-primitivism, and similar movements criticise the pervasiveness of technology in the modern world, opining that it harms the environment and alienates people; proponents of ideologies such as transhumanism and techno-progressivism view continued technological progress as beneficial to society and the human condition. Indeed, until recently, it was believed that the development of technology was restricted only to human beings, but recent scientific studies indicate that other primates and certain dolphin communities have developed simple tools and learned to pass their knowledge to other generations.
was the second manned mission
of the Apollo space program
. Commander Frank Borman
, Command Module Pilot James Lovell
and Lunar Module Pilot William Anders
became the first humans to travel beyond Earth orbit
and into an orbit around the Moon
. It was also the first manned launch of the Saturn V rocket
. NASA prepared for the mission in only four months. The hardware involved had only been used a few times—the Saturn V had only launched twice before, and the Apollo spacecraft had only just finished its first manned mission, Apollo 7
. However the success of the mission paved the way for the successful completion of John F. Kennedy
's goal of landing on the Moon before the end of the decade. After launching on December 21
, the crew took three days to travel to the Moon, which they orbited for twenty hours. While in lunar orbit they made a Christmas Eve
television broadcast that is thought to be one of the most watched of all time.

is a custom knifemaker, martial artist
, and edged-weapons authority who founded Emerson Knives, Inc in 1996. Once known for making "art knives", he later became better known as one of the knifemakers who started the Tactical Knife trend in the early 1990s with his award winning cutlery. Emerson's knives have been displayed as museum
pieces, carried by Navy SEALs
, used by NASA
in outer space
, and have been featured in books and films, making them valuable and popular with collectors. Emerson's knifemaking career was born from his experience as an engineer and machinist in the aerospace industry coupled with his lifelong study of martial arts
. Drawing on his experience as a craftsman and engineer, Emerson has also begun making custom handmade electric guitars. Emerson's own personally developed fighting technique, Emerson Combat Systems, has been taught to police officers
, elite military units
, and civilians worldwide; making Emerson a highly sought after combatives
, and noted authority on edged-weapons in combat.
