Technological and Scientific developments in Canada from 1914 to 1929 by Phoenix Chung-Simmonds https://padlet.com/sneakyskillproperties/87zuvx14ec7riwj5 en-us 2023-03-06 01:48:05 UTC 2023-03-06 02:50:34 UTC hello@padlet.com The SONAR 350449401 https://padlet.com/sneakyskillproperties/87zuvx14ec7riwj5/wish/2504390704 Sonar is an acronym for SOund, NAvigation, and Ranging was invented by R.W. BOYLE  in 1906 At first it was used as a way of detecting icebergs. It later developed and was used to help other find objects underwater. Such as submarines, boats ,etc. This discovery was very important to Canadians because they could find almost everything that could be a threat to them underwater by using this device. The Sonar was a Huge factor to Canada's world war I success rate. The sonar went on to be used in the future influencing devices such as more technological and advanced underwater radars.

Sir John Cunningham McLennan, KBE FRS (October 14, 1867 – October 9, 1935) was a Canadian physicist. Born in Ingersoll, Ontario. He was the director of the physics laboratory at the University of Toronto from 1906 until 1932. He later sold this method and knowledge to the Canadian government where they used it in their military forces for many weapons that used chemical based reactions. Helium was also a very critical component in many fields and a huge resource so this discovery saved a lot of money for Canada and their funds during the war.

The Lewis Light machine gun was a reliable machine gun that did not weigh a lot and could be carried around making the gun very reliable and efficient. It was distributed to the allies and was one of the most effective and efficient  weapons the allies obtained during the first world war because of its lightweight. The gun weighed 28 pounds, was air-cooled and fed by a 47-round magazine

Bombardier was inspired to create the snowmobile due to the fact he almost lost his son in the snow, he lived in a more rural area up north and it was a great idea to create an efficient transportation to use in the snow. IT was an Easy and efficient way for people to move around in the snow and It was also created to hunt and trap food for areas that are more snow heavy such as Quebec or areas more up north. Lots future snow transport were inspired by Josephs snowmobile, even now but our snowmobiles have stronger engines and more control.

It was very popular due to the efficiency of the radio and all of the money that it saved with costs of batteries. The military used this to their advantage as they could use the radio as much as they wanted without a battery making this a huge positive on the war and Canada's discoveries. This discovery had a huge influence on the future of radios helping create many different variables of this product.

The team's main goal was discover a way to cure/control diabetes and being able to control the amount of metabolism. The whole research/discovery took over a year to complete (1921-1922). The discovery of insulin was very important because it helped with problems surrounding diabetes. This discovery was very important to Canadian discoveries because it was a huge discovery in the medical fields giving more diversity and gateways to fixing many problems surrounding diabetes and bodies that were unable to produce it themselves insulin.

The creation  of the gas mask was inspired from the use of poisonous gasses  being used by the Germans in the war of Yrpes. The idea of the mask was for the gas to be able to filter air for the recipient. Mainly for the battlefields at war when poisonous gases were released, the mask was used to keep the soldiers safe and filter the poisonous gases out. Before this mask was invented soldiers would have to breathe through a cloth or piece of clothing soaked with their urine to be able to breathe efficiently when they had gas attacks. This discovery was named the most important protective device of the First World War, saving soldiers from countless injuries surrounding poisonous gasses.

The variable pitch propeller was the first propeller that could adjust its angles of blades to thrust and adapt to many speeds for an aircraft. When you can control the pitch of the propeller, it improves the performance of the aircraft when it explores different speeds.  the first successful test flight with the propeller was tested in flight on a Royal Canadian Air Force Avro 504K in 1927 at Camp Borden. The military later adapted this propeller to many of their air crafts giving drivers more control etc when flying.
This discovery was important to Canadian history because it was a huge step in the development of aircrafts and planes etc. Affecting their mobility thrusts and ability to accelerate and decelerate.
