Researchers around the world depend upon having access to authoritative, up-to-date data. And for 90 years, they have relied on the CRC Handbook of Chemistry and Physics for that data. This year is no exception. New tables, extensive updates, and added sections mean the Handbook has again set a new standard for reliability, utility, and thoroughness. New tables in this edition include: Index of Refraction of Inorganic Crystals, Upper and Lower Solution Temperatures of Binary Polymer Solutions, Miscibility of Organic Solvents, Density of Solvents as a Function of Temperature, and Coefficients of Friction. The Fundamental Physical Constants section has been updated with the latest CODATA/NIST values, and the Mathematical Tables appendix now features several new sections covering topics that include orthogonal polynomials Clebsch-Gordan coefficients, and statistics.
