What you don't know are the real frauds, for example, physicists and nuclear weapons (no such thing).
As well as anything related to NASA/space/astrophysics/etc ...  Physicists are generally frauds,
nothing more than high-paid welfare workers for the government, generally speaking.

However, this goes for most "professions" ... most of them have fraudulent foundations.
I would except 4b occupations, and those professions that deal with hard factual reality, such
as engineers, chemists, non-theoretical biologists/botanists, programmers, and a few others.

Definition of PROFESSION

   1: the act of taking the vows of a religious community
   2: an act of openly declaring or publicly claiming a belief, faith, or opinion
   3: an avowed religious faith
   4a: a calling requiring specialized knowledge and often long and intensive academic preparation
   b: a principal calling, vocation, or employment
   c: the whole body of persons engaged in a calling

Anyway, if you have serious questions, I would entertain them as time permits.
People today have no idea of how tenuous, fleeting, and illusory their reality is.
It is almost like a dream that nobody wants to wake-up from.

To answer your question, University of Iowa, and Stanford.

Reality is as simple as providing and provisioning for any children that you create
with what nature has provided.  That's really the only thing man needed to learn,
but he has utterly failed to do such a simple thing that all other animals can do,
because in ignorance, he feels superior to nature in his self-idolatry.
