where C is a dimensionless constant that is a function of the ratio of the specific heat of air at constant pressure to the specific heat of air at constant volume. The value of C is also affected by radiative losses, but for air, values of C of 1.00-1.10 generally give reasonable results. In 1950, Taylor published two articles in which he revealed the yield E of the first atomic explosion, which had previously been classified and whose publication was therefore a source of controversy.
