        Nobel Prizes
 Nobel  The Nobel prize in physics 
      was first rewarded in 1901. It went to Roentgen, for his discovery of X-rays. 
      These are a form of electromagnetic waves with a very high frequency. In 
      other words, these waves consist of high energy photons. And Roentgen discovered 
      them first. (It is not too far fetched to compare his contribution to that 
      of the price winning trio Becquerel and the Curies.) In 1902, Lorentz got 
      the Nobel price, for his understanding of the electromagnetic force. He 
      described how charged particles behave in the presence of electromagnetic 
      fields. And Zeeman shared his price, for his understanding of the influence 
      electromagnetic fields have on the spectrum of atoms, i.e. on the frequencies 
      of photons radiated by atoms. 
      In 1906 Thomson got the Nobel price for his discovery of the electrical unit of charge, as manifested in atoms. A year later Michelson got the price for his construction of the interferometer, an ingenious apparatus that allows, amongst others, a precise measurement of the (constant) speed of light.  A series of prices went to the inventors and developers of quantum mechanics. 
        In 1918 Planck got the price for his successful heuristic of quantised 
        energy packages, and Einstein got the price in 1921 for his explanation, 
        on the basis of Planck's hypothesis, of the photo-electric effect. Note 
        that he didn't get the price for his brilliant contributions to special 
        relativity, or for his formulation of general relativity.   Ten years later, in 1932 Heisenberg won the price for putting his predecessors 
        theories in a unified mathematical framework called quantum mechanics, 
        and the  In 1935 Chadwick got the price for the discovery of the neutron, and a year later Hess and Anderson for finding the positron in cosmic rays. It was predicted to exist by Dirac. Fermi won the race in 1938 with his theory of nuclear reactions, and a year later Lawrence was rewarded for inventing a particular kind of particle accelerator, the cyclotron. Stern won in 1943 for his discovery of the magnetic moment of the proton.  Pauli got the price for his discovery of the exclusion principle in 
        1945. His principle is a most important ingredient in our understanding 
        of the table of Mendeljev. In 1948 Blackett's cloud chamber (for keeping 
        track of particle trajectories after scattering) won, and a year later 
        Yukawa for his prediction of mesons (particles consisting of two bound 
        quarks), and another year later Powell, for finding them.  Check also the site of the Nobel committee itself for further fun information.
