Solar Energy

The energy contained in sunlight is the source of life on Earth. Humans can harness it to generate power for our activities without producing harmful pollutants. There are many methods of converting solar energy into more readily usable forms of energy such as heat or electricity. The technologies we use to convert solar energy have a relatively small impact on the environment. However, they each have disadvantages that have kept them from being widely adopted.

In Canada, the use of solar energy to generate electricity and heat is growing quickly and is helping reduce pollution related to energy production. Despite Canada’s cold climate and high latitudes (which get less direct sunlight than mid-latitudes), solar power technologies are used in many places, from household rooftops to large power plants. The Canada Energy Regulator (formerly the National Energy Board) expects solar power to make up 3 per cent of Canada’s total electricity generation capacity by 2040.

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.

Climatology

The study of modern climatology is primarily global in perspective. The main tools used by climatologists are computer models of the atmosphere, ocean and land surface, and data inferred from SATELLITE observations.

Article

Soil Classification

Classification involves arranging individual units with similar characteristics into groups. Soils do not occur as discrete entities; thus the unit of measurement for soil is not obvious.

Nuclear Energy

Nuclear Energy is energy from the nucleus of an atom. In stars such as the sun, pairs of light atoms (mostly hydrogen) fuse together and release the radiation received on earth as solar energy.

Anthropology in Canada

Anthropology is the comparative study of past and contemporary cultures, focusing on the ways of life and customs of people around the world. Subdisciplines have developed within anthropology, owing to the amount of information collected and the wide variety of methods and techniques used in research. The main branches are physical anthropology, archaeology, linguistic anthropology, ethnology (which is also called social or cultural anthropology) and applied anthropology. In Canada, early anthropologists included missionaries, explorers and traders who documented the lives of the Indigenous people they encountered. Later, the Geological Survey of Canada played a significant role in the development of Canadian anthropology.
