Nash, it does make sense on a certain level.
As you get more education, you tend to specialize. For instance in Grade school we learn skills fundamental to us all. Reading, basic arithmatic, things we use everyday.
Then in high school we start to learn things that are the beginnings of specialization. Future medical folks take biology. Geeks take computer classes. Some of us take calculus, other chemistry.
Then in college, some go pre-med, some engineering, you get the idea.
On the engineering track you learn amout thermodynamics, beam deflections, stress and strain, metal fatigue...
Once the BS degree, maybe you continue to MS or Phd. There you write a thesis on "Temperature Effects on Flexure on Aramid Honeycomb Core Materials"
Post doctorate study, you become the world's formost authority on some minute facet of sandwich structural material as it relates to the AAMRAM.
So, as you learn more you begin to know more and more about less and less until you know everything about nothing.
