Pierre And Marie Curie

         Pierre and Marie Curie
and the Discovery of Polonium and Radium

          Introduction
          Marie and Pierre Curie's pioneer research was again brought to mind when      on 20 April last year, their bodies were taken from their place of burial at Sceaux,      just outside Paris, and in a solemn ceremony were laid to rest under the mighty      dome of the Panthéon. Marie Curie thus became the first woman to be accorded      this mark of honor on her own merit. One woman, Sophie Berthelot, admittedly      already rested there but in the capacity of wife of the chemist Marcelin Berthelot      (1827-1907).

          It was François Mitterrand who, before ending his fourteen-year-long      presidency, took this initiative, as he said 'in order to respect the equality of women      and men before the law and in reality' ('pour respecter enfin....l'égalité des femmes      et des hommes dans le droit comme dans les faits'). In point of fact - as the press      pointed out - this initiative was symbolic three times over. Marie Curie was a      woman, she was an immigrant and she had to a high degree helped increase the      prestige of France in the scientific world.

          At the end of the 19th century, a number of discoveries were made in physics      which paved the way for the breakthrough of modern physics and led to the      revolutionary technical development that is continually changing our daily lives.

          Around 1886, Heinrich Hertz demonstrated experimentally the existence of      radio waves. It is said that Hertz only smiled incredulously when anyone predicted      that his waves would one day be sent round the earth. Hertz died in 1894 at the      early age of 37. In September 1895, Guglielmo Marconi sent the first radio signal      over a distance of 1.5 km. In 1901 he spanned the Atlantic. Hertz did not live long      enough to experience the far-reaching positive effects of his great discovery, nor of      course did he have to see it abused in bad television programs. It is hard to predict      the consequences of new discoveries in physics.

          On 8 November 1895, Wilhelm Conrad Röntgen at the University of      Würzburg, discovered a new kind of radiation which he called X-rays. It could in      time be identified as the short-wave, high frequency counterpart of Hertz's waves.      The ability of the radiation to pass through opaque material that was impenetrable      to ordinary light, naturally created a great sensation. Röntgen himself wrote to a      friend that initia...
