The Periodic Table (Basher book) different group of the periodic table (hydrogen, the alkali metals, the alkaline earth metals, the transition metals, the boron elements, the carbon elements, the nitrogen elements, the oxygen elements, the halogen elements, the noble gases, the lanthanides and actinides, and the transactinides). For every type of then known atom, Basher has created a "manga-esque" cartoon, and for many types of atoms, Dingle, a high-school chemistry teacher who also developed an award-winning chemistry website has written a couple paragraphs of facts to go with the cartoon. Dingle, who says that "[s]cience is a serious business", wanted in writing the book "to
Periodic table of topological invariants (thus giving the interface a gapless edge mode at formula_87). The formula_86 term for the Hamiltonian on one side of the interface cannot be continuously deformed into the formula_86 term for the Hamiltonian on the other side of the interface. Thus (letting formula_90 be an arbitrary positive scalar) the problem of classifying topological invariants reduces to the problem of classifying all possible inequivalent choices of formula_91 to extend the Clifford algebra to one higher dimension, while maintaining the symmetry constraints. Periodic table of topological invariants The periodic table of topological invariants is an application of topology to physics. It indicates
