Data taken from scipy.constants (see file codata.py)
The values of the constants provided at this site are recommended for international use by CODATA and are the latest available. Termed the "2014 CODATA recommended values," they are generally recognized worldwide for use in all fields of science and technology. The values became available on 25 June 2015 and replaced the 2010 CODATA set. They are based on all of the data available through 31 December 2014. The 2014 adjustment was carried out under the auspices of the CODATA Task Group on Fundamental Constants. Also available is an introduction to the constants for non-experts at https://physics.nist.gov/cuu/Constants/introduction.html
