  Hello, I'm Materialscientist. I noticed that you made a change to an article, but you didn't provide a reliable source. It's been removed and archived in the page history for now, but if you'd like to include a citation and re-add it, please do so! If you need guidance on referencing, please see the referencing for beginners tutorial, or if you think I made a mistake, you can leave me a message on my talk page. Thank you.

  Please stop adding unreferenced or poorly referenced biographical content, especially if controversial, to articles or any other Wikipedia page, as you did at Esther Ku. Content of this nature could be regarded as defamatory and is in violation of Wikipedia policy. If you continue, you may be blocked from editing Wikipedia.
