Please do not make unhelpful changes to Wikipedia, like you did to Nanoparticle. The changes you made seem to be vandalism and have been reverted or removed. If you want to try changing Wikipedia to learn more about how it works, please use the sandbox. Thank you. The information you added is related to more mathematics than science. Also, the article is about a nanoparticle, not nanoscience. Angerxiety 15:08, 19 December 2022 (UTC)
