The Illuminating Geometry of Viruses (2017)

Viruses consist of a short string of DNA or RNA packaged in a protein shell called a capsid, which protects the genomic material and facilitates its insertion into a host cell. Such microscopic geodesic domes quickly became the standard way to represent icosahedral viruses, and, for a while, it seemed that Caspar and Klug had solved the problem. Twarock’s tilings therefore applied to a wider range of viruses, including the polyomaviruses and papillomaviruses that had evaded Caspar and Klug’s classification.
