Please refrain from making test edits in Wikipedia pages, such as those you made to Christiaan Huygens, even if you intend to fix them later. Your edits have been reverted. If you would like to experiment again, please use the sandbox. Thank you. Dr Aaij (talk) 16:35, 12 April 2021 (UTC)

Hello, I'm Roller26. I wanted to let you know that I reverted one of your recent contributions—specifically this edit to Treatise on Light—because it did not appear constructive. If you would like to experiment, please use the sandbox. If you have any questions, you can ask for assistance at the Help desk. Thanks. Roller26 (talk) 23:44, 31 May 2021 (UTC)
June 2022[edit]
Welcome to Wikipedia. We appreciate your contributions, but in one of your recent edits to Christiaan Huygens, 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. Adakiko (talk) 06:05, 11 June 2022 (UTC)
