Knowledge mapping in 3-D

I have this idea that as you learn you might be able to map knowledge in 3 dimensions. If you learn a lot about a very limited topic, you can view that as drilling a well about 12" wide and goes into the ground (I say into the ground, because no one that isn't a specialist can see the shaft). If you learn a lot about lots of things as a college student, maybe it is like scraping all the top soil off a square mile.

My belief is that the volume of your knowledge while mapping in 3-D grows the more you know and the harder you work. So assuming that you aren't lying on the couch watching TV a whole bunch as you get old you should grow your knowledge base, maybe even multiply it as you get older?

I was on a SIU search committee a couple of years ago. I realized that I have hired and managed more people then everyone else on the search committee combined. Looking back I'm not sure how I did it, but in each of 1997 and 1998 I phone screened around a 1000 people each year, interviewed 250 or 300 in person and hired over 100 people. In 1996 I did about half that number. I never intended to become such an expert on resumes, but there you go. Made a lot of money hiring all those people, but I wouldn't want to do it again. I can't tell you have incredibly valuable this is on a day to day basis.

I caught the show about one vs. the mob or something like that on TV. Is every question about TV or pop culture on that show? Normally, I'm pretty good at the TV quiz shows, but I was amazed how trivial all their questions were. Had to switch the channel, it was a waste of time.

A question for the peanut gallery, what have you learned today, yesterday, last week, last month, in the last year? Are you writing down goals to learn new things or have you found a better way to learn?

As always, your comments are welcome.
