Electron Diffraction - History

History

The de Broglie hypothesis, formulated in 1924, predicts that particles should also behave as waves. De Broglie's formula was confirmed three years later for electrons (which have a rest-mass) with the observation of electron diffraction in two independent experiments. At the University of Aberdeen George Paget Thomson passed a beam of electrons through a thin metal film and observed the predicted interference patterns. At Bell Labs Clinton Joseph Davisson and Lester Halbert Germer guided their beam through a crystalline grid. Thomson and Davisson shared the Nobel Prize for Physics in 1937 for their work.

Famous quotes containing the word history:

    The History of the world is not the theatre of happiness. Periods of happiness are blank pages in it, for they are periods of harmony—periods when the antithesis is in abeyance.
    Georg Wilhelm Friedrich Hegel (1770–1831)

    History ... is, indeed, little more than the register of the crimes, follies, and misfortunes of mankind.
    But what experience and history teach is this—that peoples and governments have never learned anything from history, or acted on principles deduced from it.
    Georg Wilhelm Friedrich Hegel (1770–1831)
