Query: Counting rational points on a Grassmannian   We prove an estimate on the number of rational points on the Grassmannian
variety of bounded twisted height, refining the classical results of Schmidt
([12]) and Thunder ([20]) over the rational field: most importantly, our
formula counts all points. Among the consequences are a couple of new
implications on the classical subject of counting rational points on flag
varieties.
