Micromass and several Science Advisors have been working hard to further refine our math forums. Here are the changes: We renamed "Calculus & Analysis" to "Calculus" and changed the description. We add a new forum "Topology and Analysis" We renamed "Geometry and Topology" to "Differential Geometry" and changed the description. We changed the descriptions of the "linear and abstract algebra" and "Set theory" forums. We merged "number theory" with the "linear and abstract algebra" forum. Over the next few weeks staff will be moving threads into the new "Topology and Analysis" forum.
