Elliptic de Sitter space is a maximally symmetric spacetime that isn't time-orientable. Quantum field theory in this spacetime does not exist globally, but only for individual observers. This provides a working model for Susskind's horizon complementarity principle. I motivate a recipe for translating states and observables between the world-pictures of the different observers. In particular, we recover the thermal state at the cosmological horizon temperature as a state on which all observers agree.

Understanding biological heterogeneity with CyTOF-2 Mass Cytometer.

The ability to send a wave to fetch an object from a distance would fulfill many dreams. It was known since Stokes that propagating small-amplitude potential waves only push particles in the direction of propagation. I describe the experiments which show that when waves become three-dimensional as a result of the modulation instability, a floater can be forced to move towards the wave source. The mechanism for this is the generation of surface vortices by waves propagating away from vertically oscillating plungers. That introduces a new conceptual framework for understanding wave-driven flows, which enables us to engineer inward and outward surface jets, stationary vortices, and other complex flows. The results form a new basis for the remote manipulation of objects on fluid surfaces and for a better understanding of the motion of floaters in the ocean, the generation of wave-driven jets, and the formation of Lagrangian coherent structures.
