Give them a break. They don't have the luxury of a highly-structured field, purposefuly constructed by humans (engineers & mathematiciens on top of that) with only 50 years of legacy.

They have to deal with a field that was haphasardly constructed by nature over the course of 4 billion years.

Imagine having to retro-document a code base with 4 billion years of history, created solely by junior developers fresh out of college..
