The Periodic Table of Science Fiction possibility not normally open to a writer." The print edition was published in 2005, in two signed limited editions: one slipcase hardback edition with a print run of 200, and one hardback edition with a print run of 500 books. In 2009, Swanwick posted the stories on a weblog dedicated to the purpose. The theme of each story in the collection is inspired by the element it is named after. The book also includes an afterword by the author, and a foreword by Theodore Gray who was awarded the IgNobel Prize for Chemistry in 2002. The Periodic Table of Science
Periodic table of topological invariants dimensions can be labeled by the elements of the formula_46-th homotopy group of the symmetric space. These groups are displayed in this table, called the periodic table of topological insulators: There may also exist weak topological invariants (associated to the fact that the suspension of the Brillouin zone is in fact equivalent to a formula_66 sphere wedged with lower-dimensional spheres), which are not included in this table. Furthermore, the table assumes the limit of an infinite number of bands, i.e. involves formula_67 Hamiltonians for formula_68. The table also is periodic in the sense that the group of invariants in formula_46
