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.

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.

The Brooks Aqueduct, located about 8 km southeast of Brooks, Alta, is considered by many to be one of the most significant engineering feats in Canada. It has been declared both a national and a provincial historic site.

In 1922, Athanase David, then secretary of the Province of Québec, created 2 prizes to recognize and encourage the work of Québec writers and scientists. The David Prize was created for literature and the Scientific Prize for research.

One of the most famous railway accidents in recent years was the 1979 "Mississauga Derailment". There were no injuries, but the accident involved leaking chlorine cars and forced the evacuation of 250 000 nearby residents.

Kinesiology, a branch of the educational curricula of every province in Canada which originated with a variety of forms of activity and concepts such as drill, calisthenics, gymnastics, physical training and physical culture.

Radium (Ra) is a rare radioactive metal found with naturally occurring URANIUM (about 1 part radium to 3 million parts uranium). It was discovered in 1898 by Pierre and Marie Curie and G.

Population genetics is the area of genetics that studies the distribution of genes (the units of genetic inheritance) and genotypes (the genetic complement at one or more loci), and the mechanisms determining genetic variability within a population.

"Research and Development" is a phrase used to denote activities the overall goal of which is to gain and use knowledge. These activities are normally well organized, making use of the methods of various branches of knowledge and the services of highly trained personnel.

Far more significant were the fewer, larger mills cutting logs for export. Equipped with gang saws and ancillary machinery, they produced better lumber faster. After 1840 new technologies increased their size and efficiency. Circular saws were used for edging and trimming.

The OrganismThe organism that causes salmonella is a genus of bacteria of the family Enterobacteriaceae, members of which are commonly found in the intestinal tract of humans and other animals. It is named after D.E. Salmon, the American bacteriologist who described it in 1885.

How the world began is a question as old as the human race. It was not before the 20th century, however, that the evolution and large-scale structure of the universe emerged as a well-defined problem of interest to science.

After an unsuccessful attempt to form a research council in 1930, the Saskatchewan government established the Saskatchewan Research Council in 1947.

Scurvy is a disease caused by a dietary deficiency of vitamin C (ascorbic acid). The disease has occurred with regular frequency throughout human history and prehistory in populations lacking fresh foods, especially vegetables and meat.

Safety Standards, documents or codes which describe characteristics or usage for products, materials and services, are intended to protect citizens from the hazards of technology.

Interspecies gene transfer occurs naturally; interspecies hybrids produced by sexual means can lead to new species with genetic components of both pre-existing species. Interspecies hybridization played an important role in the development of domesticated plants.
