It’s fitting that this year, it was won by an image of a single atom, as it shows just how much you can say through a single image.ĭavid Nadlinger, says that the photo idea came as a way to bridge the invisible, microscopic world of the quantum world with our macroscopic, everyday life. They are used to construct extremely accurate clocks or, as in this research, as building blocks for future quantum computers, which could tackle problems that stymie even today’s largest supercomputers.”The EPSRC content allows researchers and doctoral students to share another side of their work. Supports various filetypes and custom image resource directories. Laser-cooled atomic ions provide a pristine platform for exploring and harnessing the unique properties of quantum physics.

When illuminated by a laser of the right blue-violet color, the atom absorbs and re-emits light particles sufficiently quickly for an ordinary camera to capture it in a long exposure photograph. It is held nearly motionless by electric fields emanating from the metal electrodes surrounding it. “In the center of the picture, a small bright dot is visible – a single positively-charged strontium atom. Immediately before 1913, an atom was thought of as consisting of a tiny positively charged heavy core, called a nucleus, surrounded by light, planetary negative electrons revolving in circular orbits of arbitrary radii.A mind-bending image of a single strontium atom, held near motionless by electric fields, has won the overall prize in a national science photography competition, organized by the Engineering and Physical Sciences Research Council (EPSRC).

Direct experimental evidence for the existence of such discrete states was obtained (1914) by the German-born physicists James Franck and Gustav Hertz. Atoms absorb or emit radiation only when the electrons abruptly jump between allowed, or stationary, states. The Bohr model and all of its successors describe the properties of atomic electrons in terms of a set of allowed (possible) values. The Bohr model of the atom, a radical departure from earlier, classical descriptions, was the first that incorporated quantum theory and was the predecessor of wholly quantum-mechanical models.
