Historic Newton Book Stolen From Library

Thieves posing as readers have stolen from Russia’s National Library the book in which 17th-century English physicist Isaac Newton formulated his eponymous law on gravity that revolutionized science.

The thieves stole a rare first edition of Philosophiae Naturalis Principia Mathematica from the St. Petersburg library, an official said.

The book was kept in the archives and given out for use only in the library’s reading room, the official said.
