Who is a Jew? familiar with and willing to vouch for the Jewishness of their maternal lineage or the validity of their conversion. There have been several attempts to convene representatives of the three major movements to formulate a practical solution to this issue. To date, these have failed, though all parties concede the importance of the issue is greater than any sense of rivalry among them. Ethnic Jew is a term generally used to describe a person of Jewish parentage and background who does not necessarily actively practice Judaism, but still identifies with Judaism or other Jews culturally or fraternally, or both. The
Regular solution x. The term was introduced in 1927 by the American physical chemist Joel Henry Hildebrand. Regular solution In chemistry, a regular solution is a solution whose entropy of mixing is equal to that of an ideal solution with the same composition, but is non-ideal due to a nonzero enthalpy of mixing. Such a solution is formed by random mixing of components without strong specific interactions, and its behavior diverges from that of an ideal solution only moderately. Its entropy of mixing is equal to that of an ideal solution with the same composition, due to random mixing without strong specific
