Helmholtz was one of the greatest scientists of the 19th century. He made fundamental contributions to physiology, optics, electrodynamics, mathematics, acoustics, and meteorology, but he is best known for formulating the mathematical law of conservation of energy.

With a demonstrated resolution of fractions of a nanometer, the atomic force microscope (AFM) is one of the foremost tools for imaging, measuring, and manipulating matter at the nanoscale. Unlike the electron microscope, which provides a two-dimensional image of a sample, the AFM provides a true 3-D surface profile. Though the term "microscope" suggests the visual study of minute samples, this high-tech device functions in an entirely different manner. How does the AFM gather information?
