"RadicalMath.org was launched in April 2006 by Jonathan Osler. Many of the early RadicalMath collaborators then founded the Creating Balance in an Unjust World conference on math and social justice which has taken place every few years since. Jonathan stopped updating RadicalMath in late 2007, although it continued to serve as one of the primary hubs for educators seeking resources on integrating issues of social and racial justice into their math classes."
