June 2019[edit]
Hello, and welcome to Wikipedia. Although everyone is welcome to contribute positively to the encyclopedia, at least one of your recent edits did not appear to be constructive and has been reverted. Please refrain from vandalizing articles, as you did at Nuclear technology. If you wish to experiment, please use the sandbox instead. Continued disruption may result in the loss of editing privileges. Thank you. LightandDark2000 🌀 (talk) 08:26, 13 June 2019 (UTC)
