Derek McGowan Posted May 28, 2014 Share Posted May 28, 2014 Are you familiar with the YouTube AT&T tech channel? It had archived footage of some of the great engineering accomplishments of the last century. I just watched the laying of the transatlantic phone line Link to comment Share on other sites More sharing options...
dldelancey Posted May 28, 2014 Share Posted May 28, 2014 My son likes those videos. I've never watched any myself. He also loves How It's Made and How Did They Do That. Link to comment Share on other sites More sharing options...

BaalChatzaf Posted May 29, 2014 Share Posted May 29, 2014 Are you familiar with the YouTube AT&T tech channel? It had archived footage of some of the great engineering accomplishments of the last century. I just watched the laying of the transatlantic phone lineThat was a Moment in History. The successful cable was laid out when cable ships joined their cables in mid ocean one ship headed east and the other west. They kept in touch with each other by magnetic telegraph. When they went over the horizon from each other for the first time in human history men on one ship were able to talk to men on another ship instantaneously and out of sight from each other. Man!!! That was a Moment!!!Ba'al Chatzaf Link to comment Share on other sites More sharing options...

BaalChatzaf Posted May 29, 2014 Share Posted May 29, 2014 Unfortunately, probably the last 100% secure communication link.Wire tapping was discovered very shortly after the telegraph systems were installed overland. One cannot guard all the poles.The interesting thing is that one need not physically cut into a wire. All one needs is an induction coil.Ba'al Chatzaf Link to comment Share on other sites More sharing options...

Derek McGowan Posted May 29, 2014 Author Share Posted May 29, 2014 I just watched one on the first cellphone. Seems the first network could only support three calls at a time for the entire city! Talk about beta : )About two and a half into the film we have confirmation that it was filmed before seatbelts were mandated : ) Link to comment Share on other sites More sharing options...
Selene Posted May 29, 2014 Share Posted May 29, 2014 Folks:I am amused when us 2014 citizens reverse time and are amused at how those"cretins" survived!Imagine an arthritic widow dialing a rotary phone and calling the VA about her benefits! By mail, she would have gotten better service than today.The key achilles heel of centralized power is, pure and simply, it's inefficiency.A...
