  "body": "\n## Summary\n\nA point process is a random collection of points in a space, such as the line or the plane.\nEach bounded region contains only finitely many of the points.\nIt is described as a random counting measure: for each region it gives the random number of points inside.\nThe [[Poisson point process|0MTNR28K60]] is the basic example.\nPoint processes model arrival times, positions of trees or stars, and eigenvalues of random matrices.\n\n## Explanations\n\n### L1 human\n\nThrow a handful of sand on a floor and look at where the grains land.\nThe positions form a random pattern of points.\nA point process is a model of such a pattern.\nOne describes it by counting: how many points fall in this square, how many in that disc.\nThe times at which customers enter a shop give a point process on the time line.\n",
