Welcome to Wikipedia. We welcome and appreciate your contributions, including your edits to Taxicab geometry, but we cannot accept original research. Original research also encompasses novel, unpublished syntheses of previously published material. Please be prepared to cite a reliable source for all of your information. Thank you.

 * I refer you in particular to our policy page on no original research: everything on Wikipedia must based on work previously published in reliable sources. Routine calculations are allowed: if a book gives a weight in pounds it is OK to convert it to kg, or if a person's birthdate is known it is OK to work out their age: see WP:CALC. But anything beyond this must be sourced.-- JohnBlackburne wordsdeeds 20:14, 8 June 2011 (UTC)
