Section outline

  • Three figures are shown: a many-sides spherical ball, a soccer ball and a water tower


    Figure 4.1 Nicknamed “buckyballs,” buckminsterfullerene molecules (C60) contain only carbon atoms (left) arranged to form a geometric framework of hexagons and pentagons, similar to the pattern on a soccer ball (center). This molecular structure is named after architect R. Buckminster Fuller, whose innovative designs combined simple geometric shapes to create large, strong structures such as this weather radar dome near Tucson, Arizona (right).
