DESCRIPTION:Nonlinear gravitational collapse shaped the cosmic web of gala
 xies and created a plethora of different density environments - from empty
  regions to regions crowded with galaxies. To realise the full potential o
 f upcoming galaxy surveys like Euclid and Rubin LSST\, we need to dissect 
 different density environments that are lumped together in traditional two
 -point statistics. This is particularly important for detecting extensions
  of LCDM including massive neutrinos\, dynamical dark energy  and modified
  gravity. I will show that one-point statistics not only provide informati
 on complementary to common two-point statistics\, but also allow for accur
 ate theoretical predictions of the late-time non-Gaussianity. I will expla
 in how the cosmology dependence of one-point statistics of dark matter can
  be predicted from first principles and translated to weak lensing and gal
 axy clustering observables.
