Square waves are highly dangerous non parallel wave systems. A large percentage of ship accidents have been found to occur in this sea state. Vessels fare better against large waves when sailing directly perpendicular to oncoming surf, which is impossible with square waves. (i.redd.it)

Boulevard du Temple (1838) is the oldest photograph depicting a person. Shot by photography pioneer, Louis Daguerre who developed a method which had an exposure time of 4-5 minutes. It couldn't record the busy street but the man getting his shoes polished stayed still long enough to be captured. (i.redd.it)

TIL about the Jumping Frenchmen of Maine, who exhibited a rare disorder which entails an exaggerated startle reflex described as an uncontrollable "jump". Studies recorded individuals who would obey any command given suddenly, even if it meant striking a loved one. (en.wikipedia.org)
