User talk:Quadratic formula

May 2013
Hello, I'm Discospinster. I wanted to let you know that I undid one of your recent contributions, such as the one you made with this edit to Quantum mechanics, because it didn’t appear constructive to me. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thanks, ... disco spinster  talk  19:44, 7 May 2013 (UTC)
