Hello, I'm NJA. An edit that you recently made to Quantum mechanics 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! N.J.A.  &#124; talk  11:38, 13 February 2020 (UTC)
