Aperiod of european history wherein scientific advancements were made, and logic and reason were used to advance intellectual thought was known as the period of: a. revolution b. darkness c. enlightenment d. radicalism

The Age of Enlightenment, known also as the Age of Reason, was a philosophical movement started and representative of the 18th century, in Western Europe. The main principles of the movement were individual liberty, tolerance and ending the church and state abuses. Science played a major role in the development of the Enlightenment period. Most of the thinkers and writers of the era came from scientific backgrounds. It favored rational thought above anything else and scientific progress was associated with the replacement of the old religious and traditional authority.

on this day in 1939, in response to hitler’s invasion of poland, britain and france, both allies of the overrun nation declare war on germany.

the first casualty of that declaration was not german—but the british ocean liner athenia, which was sunk by a german u-30 submarine that had assumed the liner was armed and belligerent. there were more than 1,100 passengers on board, 112 of whom lost their lives. of those, 28 were americans, but president roosevelt was unfazed by the tragedy, declaring that no one was to “thoughtlessly or falsely talk of america sending its armies to european fields.” the united states would remain neutral.

as for britain’s response, it was initially no more than the dropping of anti-nazi propaganda leaflets—13 tons of them—over germany. they would begin bombing german ships on september 4, suffering significant losses. they were also working under orders not to harm german civilians. the german military, of course, had no such restrictions. france would begin an offensive against germany’s western border two weeks later. their effort was weakened by a narrow 90-mile window leading to the german front, enclosed by the borders of luxembourg and belgium—both neutral countries. the germans mined the passage, stalling the french offensive.
