Hello, I'm Materialscientist. I wanted to let you know that I reverted one of your recent contributions—specifically this edit to Mathematical sociology—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 Teahouse or the Help desk. Thanks.

Please refrain from making unconstructive edits to Wikipedia, as you did at Agricultural engineering. Your edits appear to constitute vandalism and have been reverted. If you would like to experiment, please use the sandbox. Repeated vandalism may result in the loss of editing privileges. Thank you. Joyous! Noise! 20:43, 24 September 2023 (UTC)
