Hello, I'm Donner60. I noticed that in this edit to Arthur Ashkin, you removed content without adequately explaining why. In the future, it would be helpful to others if you described your changes to Wikipedia with an edit summary. If this was a mistake, don't worry, the removed content has been restored. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thank you. Donner60 (talk) 03:55, 3 April 2019 (UTC)

Please refrain from making unconstructive edits to Wikipedia, as you did with this edit to Arthur Ashkin. Your edits appear to be vandalism and have been reverted or removed. If you would like to experiment, please use the sandbox. Repeated vandalism can result in the loss of editing privileges. Thank you. Donner60 (talk) 03:57, 3 April 2019 (UTC)
