Artificial Intelligence (AI) in Canada

The term artificial intelligence (AI) refers to the capacity of a machine to simulate or exceed intelligent human activity or behaviour. It also denotes the subfield of computer science and engineering committed to the study of AI technologies. With recent advancements in digital technology, scientists have begun to create systems modelled on the workings of the human mind. Canadian researchers have played an important role in the development of AI. Now a global leader in the field, Canada, like other nations worldwide, faces important societal questions and challenges related to these potentially powerful technologies.

Computers and Canadian Society

Canadians use computers in many aspects of their daily lives. Eighty-four per cent of Canadian families have a computer in the home, and many people rely on these devices for work and education. Nearly everyone under the age of 45 uses a computer every day, including mobile phones that are as capable as a laptop or tablet computer. With the widespread use of networked computers facilitated by the Internet, Canadians can purchase products, do their banking, make reservations, share and consume media, communicate and perform many other tasks online. Advancements in computer technologies such as cloud computing, social media, artificial intelligence and the Internet of Things are having a significant impact on Canadian society. While these and other uses of computers offer many benefits, they also present societal challenges related to Internet connectivity, the digital divide, privacy and crime.

Clocks and Watches

The manufacture of clocks and watches in Canada may have begun as early as 1700; however, practising watch and clockmakers through the 18th and much of the 19th centuries did not make the movements.

Computer Systems Applications

MATHEMATICS spawned the computer in the 1940s and gave it its name. Its first application was the computation of theoretical ballistic tables for traditional bombs, but calculations for the atomic bomb and then for guided missiles soon became the driving force for computer development.

Robotics in Canada

Robotics is the branch of engineering that concerns robots: reprogrammable, multifunction manipulators designed to move objects and complete tasks through a variety of programmed motions. The field includes the conception, design, manufacture and operation of such machines. Robotics overlaps with a variety of other electronic and engineering disciplines including artificial intelligence (AI), bioengineering, computer science, mechatronics (the engineering of both electrical and mechanical systems) and nanotechnology. In the late 20th century, Canada distinguished itself in the field with the development of the Canadarm for space missions. Despite the challenges of competing in the international market, Canadian companies, institutes and researchers are now world leaders in the development of AI applications for robotics.

Canada's Missing Internet Wave

The idea sounded so simple and yet so revolutionary: use the Internet to exploit the buying power of far-flung individual consumers, allowing them to sign up for bulk orders on a Web site that would drive down the price of everything from video games to hand-held computers.

Canadarm

The Canadarm was a remote-controlled mechanical arm, also known as the Shuttle Remote Manipulator System (SRMS). During its 30-year career with NASA’s Space Shuttle Program, the robotic arm deployed, captured and repaired satellites, positioned astronauts, maintained equipment, and moved cargo.

Computer Science

During the 1950s, 4 main areas of focus emerged. "Hardware" concentrated on the construction of reliable equipment with faster central-processing units (CPUs), larger memories and more input and output devices to solve increasingly ambitious problems.

Gates Under Siege

They came by the thousands last week, a ragtag army of pasty-faced computer geeks in sandals and T-shirts, streaming into the San Jose Convention Center in California's Silicon Valley to honour the 29-year-old hacker from Helsinki who might just be the one to dethrone Bill Gates.

Millennium Preparations

Maj. Rod Babiuk picked up his brass abacus for a buck at a garage sale, while many of his colleagues at CFB Kingston hunted down wooden versions of the beaded counting machines. No, the army has not developed a sudden interest in ancient math.

Radar

Radio waves are part of the electromagnetic spectrum, as is visible light. H.R. Hertz provided practical demonstration of Maxwell's theory and, in 1888, actually performed radio-wave-reflection experiments.

Remote Sensing

History The oldest remote sensing instrument is the photographic camera, which has a long history of use in making observations of Earth from aircraft and, more recently, spacecraft.

Statistics

Statistics is the science concerned with the collection and analysis of numerical information to answer questions wisely. The term also refers to the numerical information that has been collected. Statistics has many applications in Canada, from government censuses and surveys, to decision making in industry, to medical research and technological innovation.
