 Polezhayev continued to write satires (describing the Russian Tsar as 'a hangman' and 'an Emperor corporal') and in the early 1830s became close to the radicals, one of whom, Alexander Hertzen, later remembered him with great warmth in his book of memoirs "My Past and Thoughts".
 A volatile and rebellious character prone to heavy drinking, Polezhayev got involved in a series of incidents, the last of which resulted in his being punished by flogging so severe, fragments of twigs had to be extracted surgically form his back.
 After that, in the course of several months, Alexander Polezhayev fell ill with tuberculosis and died.

Sparse grids are numerical techniques to represent, integrate or interpolate high dimensional functions.
 They were originally developed by the Russian mathematician Sergey A. Smolyak, a student of Lazar Lyusternik, and are based on a sparse tensor product construction.
 Computer algorithms for efficient implementations of such grids were later developed by Michael Griebel and Christoph Zenger.
