Nobel’s Dynamite (by bkang83)
Nitroglycerin was first invented by Italian chemist Ascanio Sobrero in  1846. In its natural liquid state, nitroglycerin is very volatile.  Albert Nobel understood this and in 1866 he discovered that mixing  nitroglycerine with silica would turn the liquid into a malleable paste,  called dynamite. One advantage of dynamite over nitroglycerin was that  it could be cylinder-shaped for insertion into the drilling holes used  for mining.

Enrico Fermi (1901-1954) (by Smithsonian Institution)
La prima radiografia mai fatta è del 22 dicembre 1895 ed è opera di Wilhelm Konrad Röntgen (Nobel per la fisica poi nel 1901) e rappresenta la mano sinistra di Anna Berthe Röntgen, sua moglie, all’anulare è intuibile pure l’anello.
Io questa cosa che Röntgen ha consegnato, per sempre, alla storia della medicina, della scienza (e pure della fotografia, a voler vedere) quello che è, in un certo qual modo, un ritratto di sua moglie l’ho sempre trovata bellissima.
