To tie a shoelace into a knot is a relatively simple affair. Tying a knot in a field is a different story, because the whole of space must be filled in a way that matches the knot being tied at the core. The possibility of such localized knottedness in a space-filling field has fascinated physicists and mathematicians ever since Kelvin’s 'vortex atom' hypothesis, in which the atoms of the periodic table were hypothesized to correspond to closed vortex loops of different knot types. Perhaps the most...

Dark matter plays an important role in our current understanding of the universe.  Low surface brightness spiral galaxies are particularly excellent laboratories for probing the dark matter distribution and placing constraints on theoretical models.  I will discuss the observational techniques used to study these galaxies and their dark matter halos.  I will also discuss how well current dark matter models describe the observations and suggest how they might need to be updated.

Computational fluid dynamic simulations are providing new insights into the connections between patient-specific hemodynamic flows and the initiation, progression and treatment of cerebral aneurysms. Recent studies linking aneurysm rupture to the formation of vortices have motivated the need for a more fundamental understanding of swirling blood flow patterns and their evolution during the cardiac cycle. In this talk, I describe how dynamical systems theory is being used to advance our knowledge of vortex dynamics within cerebral aneurysms.
