Like other simple models in the sciences, such as the Drosophila model of biology, the hard-disk model has needed monumental efforts to be understood. In particular, we argue that the difficulty of estimating the pressure has not been fully realized in the decades-long controversy over the hard-disk phase-transition scenario. We present the physics of the hard-disk model, the definition of the pressure and its unbiased estimators, several of which are new. We further treat different sampling algorithms and crucial criteria for bounding mixing times in the absence of analytical predictions. Our definite results for the pressure, for up to one million disks, may serve as benchmarks for future sampling algorithms. A synopsis of hard-disk pressure data as well as different versions of the sampling algorithms and pressure estimators are made available in an open-source repository. %G English %L hal-03735825 %U https://hal.science/hal-03735825 %~ ENS-PARIS %~ ESPCI %~ CNRS %~ PARISTECH %~ GULLIVER %~ L2C %~ INC-CNRS %~ PSL %~ MIPS %~ UNIV-MONTPELLIER %~ SORBONNE-UNIVERSITE %~ SORBONNE-UNIV %~ LPENS %~ UNIV-PARIS %~ UNIVERSITE-PARIS %~ UP-SCIENCES %~ ENS-PSL %~ ESPCI-PSL %~ SU-TI %~ ALLIANCE-SU %~ UM-2015-2021 %~ TEST2-HALCNRS
