Hello, I'm Anita5192. An edit that you recently made to Geographic coordinate system seemed to be a test and has been removed. If you want to 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! — Anita5192 (talk) 23:24, 20 May 2020 (UTC)

Please stop making test edits to Wikipedia, as you did to Quantum mechanics. It is considered vandalism, which, under Wikipedia policy, can lead to being blocked from editing. If you would like to experiment again, please use the sandbox. Favonian (talk) 18:47, 21 May 2020 (UTC)
