Newfoundland physicist Robert William Boyle contributed to the development of the first ultrasound detection system used by British ships in 1918. His invention was a prototype of sonar radar which allowed the allies to find and sink German submarines with much greater efficiency. -
As a plane's speed increases, the optimal angle at which the propeller blades needs to be at changes with it. So to compensate for the low efficiency at high speeds, Wallace Rupert Turnbull, a Canadian air-plane engineer, invented the first automatic variable-pitch propeller which changed the angles of the propeller blades as the plane flew. -
The Huot rifle was designed toe be a replacement to the Lewis gun (which at the time was one of the most widely used automatic rifles in the Canadian army in WWI), and it outperformed the Lewis rifle in many aspects including durability, weight, and reliability. -
In 1919, at the University of McGill, Ernest Rutherford discovered the Nucleus of the atom while studying radioactivity in the laboratories. Not only did he discover the nucleus of the atom, but also protons. This changed chemistry completely and even today we use his diagrams and use his discoveries -
Insulin was discovered by a Canadian surgeon named Frederick Banting (in the picture) in 1921. He worked with a team of three other people to purify and prepare it for human use, and in January of 1922, the first successful dose was administered to a 14 year old diabetic child. -
The world’s first electronic television was created by a 21 year old inventor named Philo Taylor Farnsworth. Before this, all televisions were mechanical and Farnsworth's television was far far ahead of even the best mechanical TV's. -
A Scanning Electron Microscope is an extremely powerful kind of microscope which shoots electrons at an object which reflect back to a sensor and forms an image. With this, scientists were able to make new discoveries which helped deepen our knowledge about medicine and atoms. -
During the battle of Ypres, Germany deployed chemical warfare on it's enemies for the first time. This brought the demand for protection against chemical-warfare. In 1916, the first gas masks were made, but they were utilised most by soldiers and civilians during the second world war in 1937.
