Wilczek responds on absolute units

In my essay "On Absolute Units, II: Challenges and Responses" (PHYSICS TODAY, January 2006, page 10), in the first column, the ratio between the fundamental mass scales in strong and Planck units should read M_strong/M_Planck ≡ (√m_p²G/ℏc).

In the second column, the ratio between the fundamental mass scales in atomic and Planck units should read M_atomic/M_Planck ≡ (√m_e²G/ℏc).
