Question

What was the social condition of Europe during the mid 18th century

Answer 1

By the middle of the 18th century, the scientific revolution was in full swing; decades of research had been compiled, exchanged, corroborated, and communicated to the public. As the most prolific mathematician and scientist of the time, Leonhard Euler made significant contributions to many different fields, including optics, mechanics, artillery, naval science, planetary motion, and several branches of calculus. More recently, the 20th century science historian Clifford Truesdell has calculated that of all the mathematical and scientific work published during the whole of the 18th century, a full 25% was written by Euler.
