Hello, I'm Bruce1ee. An edit that you recently made to Quantum mechanics ‎ 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! —Bruce1eetalk 12:15, 22 October 2018 (UTC)
