War and Peace is a literary work mixed with chapters on history and philosophy by the Russian author Leo Tolstoy. It was first published serially, then published in its entirety in 1869. It is regarded as one of Tolstoy's finest literary achievements and remains an internationally praised classic of world literature. Book 11: 1812: Absolute continuity of motion is not comprehensible to the human mind. Laws of motion of any kind become comprehensible to man only when he examines arbitrarily selected elements of that motion; but at the same time, a large proportion of human error comes from the arbitrary division of continuous motion into discontinuous elements.
