James Hillier devlopment of the Electron Microscope

As a boy, James Hillier thought he would alike(p) to be a commercial artist. Instead, he turned break 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 commencement ceremony off practical electron microscope.         Electron microscopes cultivate by stress a actinotherapy of electrons, rather than a beam of light. The wavelength of electrons is a good deal 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 done a care full(a)y prepared sample. The beam was then pore 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 first sca n electron microscope. This worked by scanning the object with a beam of electrons to produce an image similar to the one on a television screen.         After he retired, Hillier devoted himself to promoting intelligence gentility.

He now gives talks to high school students some 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 honors, including the Or der of Canada . !
