A young woman, pursuing a graduate degree in art history, was going to Italy to study the country's greatest works of art.
Since there was no one to look after her grandmother while she was away, she took the old lady with her.
At the Sistine Chapel in the Vatican, she pointed to the painting on the ceiling. 'Grandma, it took Michelangelo a full four years to get that ceiling painted.'
'Oh my, 'the grandmother says.
'He and I must have the same landlord.'
Kenichi FukuiDied 9 Jan 1998 at age 79 (born 4 Oct 1918).Japanese chemist whosharedthe 1981 Nobel Prize for Chemistry with Roald Hoffmann for investigation of the mechanisms of chemical reactions. In 1952, at Kyoto University, Fukui introduced his “frontier orbital theory of reactions.”He proposed that the course of a reaction is determined by geometry and relative energies of molecular orbitals of reactants. The theory explains electrophilic attack, for example, occurs at the carbon atom having the greatest density of frontier (highest energy) electrons. In the mid-1960s, Fukui and Hoffmann discovered—almost simultaneously and independently of each other—that symmetry properties of frontier orbitals could explain certain reaction courses that had previously been difficult to understand. |
