Hello, I'm Dr Greg. An edit that you recently made to Minkowski diagram seemed to be a test and has been removed. If you want more practice editing, please use the sandbox. If you think a mistake was made, or if you have any questions, you can leave me a message on my talk page. Thanks!  Dr Greg  talk  17:52, 9 May 2017 (UTC)
