Superslow processes are processes in which values change so little that their capture is very difficult because of their smallness in comparison with the measurement error. Most of the time, the superslow processes lie beyond the scope of investigation due to the reason of their superslowness. Multiple gaps can be easily detected in biology, astronomy, physics, mechanics, economics, linguistics, ecology, gerontology, etc. Traditional scientific research in this area was focused on the describing some brain reactions. In 2003, the term superslow processes was brought to wide attention by Russian mathematician Vladimir Miklyukov who founded Superslow Processes laboratory on the base of the Volgograd State University (Russia). Reports of seminar members are published yearly in Notes of the Seminar ''Superslow Processes''.
