Henry Taube and the Mechanisms of Electron-transfer Reactions

On November 30, 1915, Canadian-born American chemist Henry Taube was born. Taube has been awarded the 1983 Nobel Prize in Chemistry for his extensive research into the properties and reactions of dissolved inorganic substances, particularly oxidation-reduction processes involving the ions of metallic elements. Metals often form complexes, in which other atoms cluster around the metal atom, transferring and sharing electrons among themselves to bind together. Taube discovered that during a…

Helen Hogg and the Globular Clusters

On August 1, 1905, American-Canadian astronomer Helen Battles Sawyer Hogg was born. Hogg is noted for pioneering research into globular clusters (stars with cyclical changes of brightness found within huge, dense conglomerations of stars located in the outer halo of the Milky Way galaxy) and variable stars. She was the first female president of several astronomical organizations and a notable woman of science in a time when many universities would…
