The recommended CODATA 20 2 value of the inverse fine structure constant is smaller than the theoretical value in the Euclidean plane:
The data-transfer approaches associated with this data capture and storage effort are being coordinated with CODATA, which has been developing (a) a markup language called the Gas Hydrate Markup Language (GHML) [13-16] for communicating gas hydrate data throughout the research community and (b) an international hydrate portal technology for centralized access to a number of database efforts.
Figure 19 illustrates how this NIST evaluation fits in with respect to other laboratory evaluations of previous years, including the CODATA assignment of 1986.
