As a boy, James Hillier thought he would worry to be a commercial artist. Instead, he turned step up to boast a talent for mathematics and physics, and won a scholarship scholarship to the University of Toronto. There, he and fellow student Albert Prebus invented the worlds send-off practical electron microscope. Â Â Â Â Â Â Â Â Electron microscopes cultivate by steering a actinotherapy of electrons, rather than a beam of light. The wavelength of electrons is lots littler than the wavelength of light, enabling greater magnification and depth of focus. In 1938, Hillier and Prebus produced a microscope that worked by passing a beam of electrons through a care full(a)y prepared sample. The beam was then focus on a photographic plate. Their device-magnified objects to 7,000 times their size C optic microscopes produced a magnification of only 2,000 times. A fewer age later, Hillier and two other physicists developed what was arguably the low gear scan electron micros cope. This worked by scanning the object with a beam of electrons to produce an image similar to the one on a television screen. Â Â Â Â Â Â Â Â After he retired, Hillier devoted himself to promoting recognition teaching method.
He now gives talks to high school students almost careers in science. Because he would never have been able to go to university without scholarships, he established the James Hillier Foundation, which awards scholarships to promising science students in his hometown of Brantford. The knowledgeableness supports 10 science students in their pursuit of university education with $5,000 annually. His work has brought him many hon! ors, including the Order of Canada .
