What would Edison make of the last decade? (Or my grandfather to come to think of it)

My knowledge (though not my understanding) of the technological advances of the last 150 years are informed by Stephen Lax

Reflecting on how I blog and its value to a student I note here how, believing I may need to go back and read Wenger from last week I search here and find not only have I done the reading, but I have commented on Wenger in previous weeks and modules.

This immediately bolsters my confidence, like entering a room that I thought was full of strangers when in fact there are many faces I have met before.

What is more, knowing that I can trigger my earlier thinking, even pick up the stage in understanding that I was at, is a form of adaptation.

I wonder if this practice might help from the other direction too, reminding someone of the nuances of their understanding and how it has been informed and developed.
