Isolated physical systemA physical system is said to be isolated if it does not interact with anything. Isolated physical systems follow a number of conservation laws. As a concrete example, consider the following situation. Suppose you are standing still on the perfectly icy (i	IsomerIn chemistry, isomers are molecules with the same chemical formula and often with the same kinds of bonds between atoms, but in which the atoms are arranged differently. Many isomers share similar if not identical properties in most chemical contexts.	IsotopeIsotopes are atoms of a chemical element whose nuclei have the same atomic number, Z but different atomic weights, A''. The word isotope meaning at the same place comes from the fact that isotopes are located at the same place on the periodic table. The a
Isomorphism classAn isomorphism class is a collection of mathematical objects isomorphic with a certain mathematical object. A mathematical object usually consists of a set and some mathematical relations and operations defined over this set. Isomorphism classes are often	IsomorphismIn mathematics, an isomorphism is a kind of interesting mapping between objects. Douglas Hofstadter provides an informal definition: :The word "isomorphism" applies when two complex structures can be mapped onto each other, in such a way that to each part	IsotropicIsotropic means "independent of direction". Isotropic radiation has the same intensity regardless of the direction of measurement, and an isotropic field exerts the same action regardless of how the test particle is oriented. Isotropy is also a concept in
