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.
The Toronto Magnetic and Meteorological Observatory
is a small observatory
located on the grounds of the University of Toronto
. The original building was constructed in 1840 as part of a worldwide research project run by Edward Sabine
to determine the cause of fluctuations in magnetic declination
. Measurements from the Toronto site demonstrated that sunspots
were responsible for this effect on Earth's magnetic field
. When this project ended in 1853, the observatory was taken over by the Canadian government, greatly expanded in 1855, and operated as the primary meteorological station and official Canadian timekeeper for over fifty years. The Observatory is the country's oldest surviving scientific institution, and is considered the birthplace of Canadian astronomy.

Did you know...
(1728–1809) was an English manufacturer
and the partner of engineer James Watt
. In the final quarter of the 18th century, the partnership installed hundreds of Boulton & Watt steam engines
, which were a great advance on the state of the art, making possible the mechanisation of factories and mills. He became associated partner with James Watt when Watt's business partner, John Roebuck
, was unable to pay a debt to Boulton, who accepted Roebuck's share of Watt's patent
as settlement. He then successfully lobbied Parliament
to extend Watt's patent for an additional seventeen years, enabling the firm to market Watt's steam engine
. Boulton applied modern techniques to the minting of coins, striking millions of pieces for Britain and other countries, and supplying the Royal Mint
with up-to-date equipment. Boulton was a key member of the Lunar Society
, a group of Birmingham-area men prominent in the arts, sciences, and theology. Members included Boulton, Watt, Erasmus Darwin
, Josiah Wedgwood
, and Joseph Priestley
. Members of the Society have been given credit for developing concepts and techniques in science, agriculture, manufacturing, mining, and transportation that laid the groundwork for the Industrial Revolution
and for later discoveries, including the theory of evolution
