“Hypsicles added a Book XIV to the Elements which dealt with the mensuration of the regular dodecahedron and icosahedron.”

“Water, because it is the most mobile and fluid, has to be an icosahedron, the regular solid that rolls most easily.”

“He developed a theory of automorphic functions, connecting algebraic and geometric results in his important 1884 book on the icosahedron.”

“For example, fair dice don't have to be in the shape of regular polyhedra, such as cubes, icosahedra, and so on.”

“The smallest particles of fire are tetrahedra, of air octahedra, of water icosahedra.”

“We then use the model to determine the population of icosahedra in mesoclusters at arbitrary temperature.”

“The number of contacts per residue was calculated for the monomers, the pentamers, and the icosahedrons.”

“Viruses of these two families are icosahedrons and contain nucleic acids with limited genetic information.”

“This family convinced me that one could assemble equilateral triangles in order to create volumes different from known Platonic ones, such as tetrahedrons, octahedrons, and icosahedrons.”
