Subject: [CDXAmembers] Old documentaries about lasers, fiber and the transistor

 

From AT&T archives here are two interesting videos.  The first is a demonstration of lasers, and fiber technology.

 

 

The second is a 1953 documentary about the progression from the development of the vacuum tube to the transistor and predictions for the future.

 

 

 

Great for a rainy day between contests.
