An increasingly studied class of systems comprise colloidal particles
that move by self-propulsion rather than Brownian motion. Such
dynamics violates time-reversal symmetry at the microscale,
undermining one of the pillars on which equilibrium thermodynamics is
built. What remains? I will address this question in the specific
context of calculating the pressure of a system of active particles,
defined as the force per unit area on a confining wall.
