I am asking this question based on my recent experience as a physics major at a well-known school of science and engineering. My basic question is,

Why does the field of physics (at least at an undergraduate level) seem to be exclusively concerned about the "really small" scale and "really large" scale phenomena, and virtually nothing in between?

Background: I began college with a certain idea of what I thought physics was all about, the things I may end up studying, and boy was I wrong. To explain, I thought I would be learning about more "tangible" things, like things on the human scale. Examples of this might be fluid flow, acoustics, combustion/heat transfer, high speed collisions (not between particles), etc. I believe this first impression of physics was due to my experience in classes like Physics 101, where basic concepts like friction, kinetic and potential energy, spring systems, circular motion, and so on, were taught. 

As the years went by, I very much lost sight of those expectations, learning mostly about quantum mechanics, solid state physics, electricity/magnetism, and relativity. I understand the practicality and usefulness of these topics in our modern world. What I am curious about is, why is the human-scale phenomena almost completely neglected in the undergraduate physics education? Or is this not true of other physics programs? I can not accept the answer that my friends have given, which is along the lines of "there is no interesting phenomena at that scale"... this just seems mislead. 

So in summary, I am wondering if anyone has a reasonable explanation for why the "human-scale" (in between planetary and microscale) phenomena seems to be completely neglected at the undergraduate physics level.
