A careful analysis of the process of observation in atomic physics has shown that the subatomic particles have no meaning as isolated entities but can only be understood as interconnections between the preparation of an experiment and the subsequent measurement. ~ Erwin Schrödinger
Matryoshka are diminishing self-similar hollow dolls that can be nested one inside another. Matryoshka derives from the Russian peasant name for females: Matriosha or Matryona, derived from the Latin root mater, meaning mother.
In 1890, Russian painter Sergey Malyutin designed the first Russian Matryoshka doll, which was carved by Vasily Zvyozdochkin, a Russian craftsman. Malyutin painted the dolls.
Matryoshka dolls are sometimes called babushka dolls, the Russian word for grandmother.
Like the dolls themselves, the history of the Matryoshka doll is nested. The concept predates Malyutin, who was inspired by a wooden doll brought to Russia from the Japanese island of Honshu. The Japanese claim that their dolls derived from the earlier work of a Russian monk, who had created a doll to represent a Buddhist sage.
