History of Mathematics in Canada

Every Canadian university has a mathematics department and offers one or more programs in this field. The same is probably true of almost every university throughout the world, a reflection of the importance of mathematics in contemporary society (see Mathematics and Society). Mathematics came to prominence as a scientific discipline after the Renaissance, during the period historians call the Scientific Revolution (1450-1700), when brilliant astronomer-mathematicians such as Copernicus and Newton discovered the true nature of the solar system, with the sun at the centre and the planets revolving around it. (See also Astronomy.) The role that mathematics played in these major discoveries gave the discipline the stature it has maintained to this day.

Hospital Architecture

From the 17th century until about 1900, hospitals in what is now Canada were unspecialized, multi-purpose institutions for the sick poor. Until around 1900 those able to pay doctors preferred to be treated at home. The first hospitals emerged in places where people were unable to get medical treatment by physicians in their own homes. The financial sources and social mandates of hospitals have varied widely over the past 400 years. The earliest hospitals included military and marine hospitals, as well as Roman Catholic and then Protestant benevolent institutions. By the turn of the 20th century, the administration of scientific medicine was the major purpose of the Canadian hospital. Since about 1970, hospitals have become increasingly specialized; structurally they have become flexible and expandable.

Hydroelectricity in Canada

Hydroelectricity is energy produced from flowing water. The amount of energy produced depends on volume and speed: the more water moving at a fast rate, the more energy produced. For this reason, many hydroelectric stations are built near waterfalls. To produce energy, water is directed toward turbines — sometimes with the help of a dam — causing them to spin. In turn, the turbines make electrical generators spin and electricity is produced. It is a renewable, comparatively nonpolluting energy source and Canada’s largest source of electric-power generation.
