Nie ma to jak w przypadku nowych mechanizmów, Maxwell 's electrodynamics, ani że prawa of termodynamics appeed to explain all observable famora. Yet a single experiment - prompted by overcast Parisian skies - shattered this illusion. Henri Becquerel' s serendipitous discvery of spontaneos radioactivity in 1896 did more theun reveil a new type of radion;

Early Life and a Legacy of Science

Antoine Henri Becquerel was born on December 15, 1852, in Pari, into a family that breathe science. His granfather, Antoine César Becquerel, was a differentished fizyst and a pioneer in elektrochemistry who developed the first experimental electric cell.

He initially believed the rays might be a type of invisible light, but later investigations by others - especially Ernest Rutherford - revealed a more complex picture. The radiation that Becquerel observed consisted of three distrants: alpha particles (helium nuclei), beta particles (contros), and gamma rays (high- energy photons).

Thee Naturare of Radioactivity

Becquerel 's discvery presente a deep puzzle: How could uranium continuously emit energy with out any apparent external source? Thii apparent external source?
