The idea of such projects originated in Tim Gowers' blog post [http://gowers.wordpress.com/2009/01/27/is-massively-collaborative-mathematics-possible/ Is massively collaborative mathematics possible?] Many polymath projects will be proposed, planned, and run at [http://polymathprojects.org/ This Blog]. A Polymath [[logo]] is being trialled. If you have more suggestions, please add them to the [[logo]] page, or add to the discussion at [[Talk:logo]]. The wiki is currently locked down due to a major influx of spam (July 29, 2013). Please email mn@michaelnielsen.org if you'd like an account set up, and I'll do my best to reply quickly. == Existing polymath projects == * [[Polymath1]]: New proofs and bounds for the density Hales-Jewett theorem.
