Great Scientists Insert Name
Who was it? Born in South Dakota, 1901 Made vital contributions to atomic bomb Invented cyclotron that accelerated particles to high velocity without high voltage, used to make new elements Developed e/m ratio of electron Liked “Lawry’s” seasoned salt
Ernest Lawrence 1901-1958 Invented cyclotron, 1929 – Accelerated particles to bombard with atoms Made new elements Made anti-matter to study Won Nobel prize in physics, 1939
Who was it? Born in Copenhagen in 1885 Researched structure of the atom First to postulate that electrons travel around nucleus of atom Predicted splitting of uranium atoms Gave lectures, never “boring”
Niels Bohr 1885-1962 Known for the Bohr model of the atom – Electrons travel around nucleus in restricted orbits Won Nobel prize in physics in 1922
Who was it? Born in Württemberg, Germany, 1879 Postulated light travels in individual photons, 1905 Wrote special theory of relativity 1905 Wrote general theory of relativity 1916 E mc2
Albert Einstein 1879-1955 Postulated photons travel in discreet energy packets (individual photons) Theories of special and general relativity Nobel prize in physics, 1921
Who was it? Born 1852 in Paris Discovered natural radiation in uranium in 1896 Unit of radiation named after 1 disintigration/second 1 Bq “Oh Henry!”
Henri Becquerel 1852-1908 Known for his discovery of natural radiation in uranium Shared Nobel Prize with the Curies in 1903
Who was it? Born in Rome, 1901 Contributed to early theory of beta decay and neutrino Demonstrated nuclear transformation with neutrons in elements Led experiment that performed first controlled nuclear reaction Very “fair to me”
Enrico Fermi 1901-1954 Discovered neutrino and neutron activation Work led to fission and controlled nuclear reaction Nobel prize physics, 1938
Who was it? Born in Nelson, New Zealand, 1871 Discovered alpha and beta particles in 1898 Devised method of counting alpha particles with H Geiger Investigations of alpha scattering in 1910 led to the discovery of the nucleus Knighted in 1914
Sir Ernest Rutherford 1871-1937 Discovered alpha and beta particles Discovered nucleus in 1910 Won Nobel prize in chemistry, 1908
Who was it? Born Frankfurt-on-Main, Germany, 1879 Discovered radiothorium, radioactinum, and mesothorium Developed methods of separating radioactive particles Discovered fission by bombarding uranium and thorium with neutrons, 1938 with Strassman Lets all give him a “hand”
Otto Hahn 1879-1968 Discovered the process of fission by bombarding uranium with neutrons (including the chain reaction) Won Nobel prize in chemistry in 1944
Who was it? Born in Warsaw, 1867 Discovered radium and polonium and developed means to separate it Refused to patent work for money Developed unit of radioactivity – 1 Ci 37,000,000,000 disintigrations/sec There was no “cure” for her radiation
Marie Curie 1867-1934 Known for her discovering and separating radium and polonium Shared Nobel prize in physics, 1903 and full prize in chemistry, 1911 – (First to receive two prizes)
Who was it? Born in 1978 Isolated protactinium with Otto Hahn in 1917 Worked with Hahn on behavior of beta rays Helped discover fission with Hahn and Strassman “Meitnerium” named after her (elm 109)
Lise Meitner 1878-1968 Spent much of career working with Otto Hahn – Helped discover fission with Hahn and Strassman – Discovered elements with Hahn
Who was it? Born in Lennep, Germany, 1845 Worked on thermal conductivity of crystals Discovered X-rays Unit of radiation named after him for dose (R) He had the “will” to do it
William Röentgen 1845-1923 Discovered x-rays in a cathode tube experiment Won Nobel prize in physics in 1901
