Please refrain from making unconstructive edits to Wikipedia, as you did at Doppler effect. 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. Favonian (talk) 18:33, 1 February 2020 (UTC)

Recent request at the teahouse
Hi! I just noticed you created a new section at the teahouse, a place for getting help with using or editing Wikipedia. The content of the section appeared to be nonsense and I have removed it. Did you need help with something in particular? If you only meant to make a test edit, please use the sandbox instead, so you don't disrupt others using Wikipedia.
