For all of the problems in Russia right now, the relics of the Soviet education system persist. Here is the pile of books for a 13-year old daughter of a former colleague. Not a bad mix.
(geometry, probability and statistics, algebra, informatics, literature and art)
My Russian has decayed over the decades, but the introduction to that physics book looks pretty good.
My guess is the history and current events material is bizarre, but I really wish US schools had this level of material.
I thought of her when we were walking through the woods on the weekend to visit the redwoods (our neighbors).
Underneath the trees, there were still some blooms from the Redwood Sorrel.
Redwoods are a great metaphor for rebirth and resilience. It is in their nature.
This is what a 3d Dirichlet distribution looks like for different levels of distribution parameter.

d = Dirichlet(3, alpha)
pr = [0 -sqrt(3)/2 sqrt(3)/2; 1 0 0]
s = [ntuple(i->x[i],2) for x in eachcol(pr* rand(d, 20000))]
