The Application of Science to Engineering Improvements in engineering are very important to the industrialization and prosperity of a country. Although engineering improvements sometimes come through trial and error they are most often achieved by applying pure science and mathematics to engineering. Canadian engineering was improved a great deal in this manner. The engineering associated with building materials and long distance communication, two of Canada's most important industries, was improved through the application of pure science. One of the most important scientific discoveries of all time was the law of electromagnetic induc
