Quantum resonance. Sequence of 3 computer models showing the development of quantum resonance in a cavity. At left, two quantum wavefunctions spread out from their start point as circular waves. They hit semicircular barriers (black) and reflect back and forth (centre). Wavelengths of the right size will resonate in the cavities and accumulate. This corresponds to trapping particles (like electrons) of a certain energy. Because they also behave as waves, diffraction also occurs and the waves can leak past the edges of the barriers and through holes. This started at centre, and further spread of the waves is seen at right. This model was created as an artwork by Professor Eric Heller.
Science Photo Library was founded in 1981 by Michael Marten, one of the authors of "Worlds Within Worlds", a book exploring different ways to observe the universe - from electron micrographs, to images of earthrise taken from the Apollo spacecraft. When Marten started receiving requests for the beautiful images in the book, he had an idea of setting up Science Photo Library.
Since then, Science Photo Library has continued to work alongside world acclaimed photographers and the leading science and medical experts to provide a central source of the best science and specialist imagery available. Although the collection started with scientific images, it has grown to encompass all aspects of science and their impact on everyday life.
