Welcome to Wikipedia. We appreciate your contributions, but in one of your recent edits, it appears that you have added original research, which is against Wikipedia's policies. Original research refers to material—such as facts, allegations, ideas, and personal experiences—for which no reliable, published sources exist; it also encompasses combining published sources in a way to imply something that none of them explicitly say. Please be prepared to cite a reliable source for all of your contributions. You can have a look at the tutorial on citing sources. Thank you. Materialscientist (talk) 10:54, 14 October 2022 (UTC)

Hello, I'm Riverbend21. Wikipedia is written by people who have a wide diversity of opinions, but we try hard to make sure articles have a neutral point of view. Your recent edit to University of Pisa seemed less than neutral and has been removed. If you think this was a mistake, or if you have any questions, you can leave me a message on my talk page. Thank you. Riverbend21 (talk) 09:40, 15 October 2022 (UTC)
