This is my take on the subject, and it's just a small one. Back in the mid-60's. I was in the Navy, and was sent to electronics school in Greatlakes Ill. One of the subjects we were studying was transistor applications. We were told that Bell Labs invented the transistor in 1947,(same year as Roswell crash). Transistors were seen to be the new electronics wonder, and were to replace the current vaccume tubes, in the future. Now to put this into context, the vaccume tube started life in the turn of the 19th. century, and slowly evovled in complexity over the decades. Then in the span of just a few short years the transistor came into use over night. and in less then fifteen years evolved into the intigrated circuit. In otherwords 50 to 100 years of vaccume tubes and less than 20 years, transistors/intigrated circuits??? Holes don't flow, electrons do, as the instructors used to say,(co-valance bonding). Not that we humans aren't capable of great leaps in progress, but some times things just don't look right...
