Research on the teaching and learning of physics suggests principles that can guide the development of classroom environments where students have the opportunity to take on a more active role in their own learning and to develop a robust conceptual understanding.

When a tsunami arrives a coast, it often breaks offshore and forms a bore. In my talk, I first address a fundamental question, how vorticity (fluid rotation) is generated and leads to the formation of a turbulent flow in a bore (defined as a quasi-steady broken water wave of an infinite wave length) propagating into a quiescent water of a uniform depth. Then, the similar question can be asked for some extended conditions, which includes backwash flow caused by the earlier tsunami runup, for example.

Over the past few years, during discussions with thought leaders in academia about future research directions, my attention was drawn to a number of powerful and recurrent themes. Insights from these conversations, enhanced by examining recent changes in funding policy and new approaches to research, have illuminated a number of salient, unpredictable and sometimes disconcerting trends. It is clear to many that computing has become indispensable for creating scientific advances needed to solve immensely complex problems that are highly important to society.

An overview from our lab will highlight the results from cellulose nanocrystal (CNXL) research in diverse areas to include: CNXL-filled polysulfone CNXL-filled carboxymethyl cellulose CNXL-filled cross-linked poly(vinyl alcohol) as a barrier to toxic industrial chemicals CNXL-DNA hybrid nanomaterials CNXL dispersions and the Kerr effect It is hoped that the results will prove to be convincing evidence of the potential of CNXL-based nanotechnology for a variety of potential applications.
