Please stop adding nonsense to Wikiquote, as you did to Henri Poincaré. It is considered vandalism. If you would like to experiment, use the sandbox. Wikiquote exists for the collecting of notable quotations of famous people and famous works. For a quick overview of what Wikiquote is, read Wikiquote, and also What Wikiquote is not for a list of common activities that Wikiquote does not support. When people are not interested in responsibly contributing to the development of the project, incidents of their deliberate vandalism can result in IP addresses being blocked from editing. Thank you. ~ Ningauble (talk) 21:46, 2 May 2013 (UTC)
