For the creation of Derivative of the exponential map‎, a truly salutary tasteful contribution to WP. Cuzkatzimhut (talk) 12:36, 3 December 2014 (UTC)

For all your work on the Lorentz group and related articles. Excellent work! M∧Ŝc2ħεИτlk 19:03, 10 April 2014 (UTC)

Hi

Thank you for reverting my mistake. I was using energy momentum tensor written in this page which is not devided by c^2: Electromagnetic stress-energy tensor I think these two page have a conflict in definition! Is that true?
