Sharp Shapes from Soft Systems

What determines shape? Energy minimization in flexible systems with competition between order and shape change can lead to a wide variety of shapes including highly faceted singular structures. I will discuss shape generation and shape shifting in two systems – molecularly thin vesicles with liquid crystalline order and fluid droplet networks with osmolarity gradients.

Thought as a Technology

It is a common observation that technology can change and augment the way we think. In one common account, we outsource problem-solving to technology: we ask questions of search engines, use maps to navigate and understand our environment, and so on. In this talk I develop the more radical idea that our thoughts themselves are, in important ways, technologies. In particular, by inventing more powerful user interfaces, we can expand the range of thoughts human beings can think. I will discuss numerous examples, including interfaces for exploring 4-dimensional space, Euclidean geometry, and several other domains traditionally regarded as difficult for humans to think about.

Emergent properties in experiments with synthetic micro-swimmers

Active or energy-consuming microparticles are intrinsically out-of-equilibrium. This renders their physics far richer than passive colloids and give rise to the emergence of complex phenomena e.g. collective behavior or self-propulsion.. I will present a variety of non-equilibrium phenomena observed with experimental realization of synthetic micro swimmers: dissipative self-assembly, sensing of the environment, or effective interactions, in the absence of any potential...
