  2. Life Profile • Born in Stockholm, Sweden in 1833 • Father was Immanuel Nobel • Mother was Andriette Ahlsell Nobel • Has three brothers The house where Alfred Nobel was born. Alfred Nobel

  3. 1842 1850-1852 1860 1896 Family reunited in St. Petersburg Life Profile Travelled to Paris, Italy, Germany and the U.S.A. Started his experiments with nitroglycerin Suffered a stroke, and died in the villa in San Remo, Italy

  5. Academic achievementInvention of dynamite • Mixing nitroglycerin, diatomaceous earth and a small admixture of sodium carbonate • Diatomaceous earth turn the liquid into paste which could be shaped into rods • Invent detonator and blasting cap dynamite

  6. Academic achievementInvention of dynamite - nitroglycerin • Derived from glycerol molecule • Contains oxygen, nitrogen and carbon • A lot of energy is released when it explodes • The speed of the decomposition reaction makes nitroglycerin a violent explosive nitroglycerin

  7. Academic achievementUses of dynamite • Construction 。 drilling tunnels。 blasting rocks。 demolition • Mining • Weapons • Underwater blasting water blasting
