In general, what do you think was the effect of Science in WWI and WWII?

The Second World War was a conflict that saw a great deal of scientific and technical innovation. The war was a battle of scientific minds as well as of bullets and bombs and the wartime research programs came up with many important developments to help give the Allies an advantage in the struggle. As with many other aspects of the Allied war effort, Canada played an important role.

Much of the research found civilian uses after the war and has helped shape today's modern world. Whenever you heat food in a microwave oven or use washer fluid to clear off a car windshield, to name just two examples, you can credit the groundbreaking work done by Canadian scientists during the Second World War.
