A weekly meeting to discuss a publication in the area of soft-condensed-matter physics. Examples of soft matter include colloids, emulsions, polymers, gels, glass, granular media, membranes and other squishy materials. We encourage students to attend and participate in these informal discussions with colleagues and faculty. Attending is a great way to stay current with developments.
Please consider volunteering to lead a discussion. The key step is simply to choose an article; it is not necessary to be an expert in the field or to defend the conclusions of the article.
