'In World War II in Great Britain, all church bells were silenced, to ring only to inform of an invasion by enemy troops. The episode "The Battle of Godfrey's Cottage" of the BBC sitcom "Dad's Army" included a scene where the church bells rang by mistake, leading the Home Guard to believe that an invasion was taking place.
From student LF.
Bells was Europe's communication and control mechanism. Around the middle ages every village had a church with bell tower. Bells rang to communicate time and when it was time for prayer. We use bells in this school. There were also bell tunes for specific events.
The North American Indian are famous for using smoke signals.
This lesson we saw the fascinating interaction of electric charge and the bodies own internal communication system of nerves as the hand jumps.
