I chose this  paper for 3 reasons.

1st.One is not supposed to understand the physics. It is the form of the presentation that is important. It is a form all scientist use to describe their work it contains all those things that are important in making the work of a scientist  reliable dependable honest and  trust worthy  independent  of their personal reliability.

This paper  was written by J. R. Oppenheimer

Early in his career he  submitted this paper in May 15, 1928 to the Journal of the National Academy Of Sciences. In response to the newly formed ideas in quantum theory.

2nd., It's short, and deals with  a single issue.  It is not an outstanding paper but just one of those run of the mill piece of work that all research scientists publish as part of their job.
3rd,  I chose this because it's a typical refereed peer reviewed paper  and  represents what  such a paper  looks like.

One should look at the style of how the content is organized, see the detail of the analysis, the comparisons against other explanations, and the references including a personal  communications from a competitor.

The very successful progress that basic research has enjoyed over the centuries has been through the way research is judged, tested and reported. The reporting structure is through the language of  mathematics which has a fixed grammar and where everything is reduced to just three testables  length, mass, and time. It has to be repeatable by other laboratories and basic research scientists. This is  where basic research uses its testable honesty rule.

This community  of  basic researchers is small, inclusive, & exclusive. It's a challenge to become a citizen, break the rules you  permanently lose your citizenship. The work is  fiercely completive.  To win the race in making  the discovery first,  researchers  must work closely together with their  competition. Basic researchers depend on each other's work. Everyone's research work has be done correctly with no question of honesty. It is a disaster and visible to all if the rule is broken.

Basic Research is truly a remarkable island of truth in a world filled with miss-interpretations. Its citizens have the same self serving interest, greed, selfishness, etc. etc. as other  homo sapiens but the  basic research scientists  uses auto  honesty testing  in its work.  Bad  research surfaces quickly, and  its authors disfranchised  from the community

The discoveries gained through basic research have made a larger impact on the physical quality of our life than any other community  look around us at what this community has done for mankind. Measure it statically comparing  and normalizing our total physical quality of life today with what we had centuries ago. The engine that drives basic research scientist  is competition. The principal reason for their success is testable honesty.

There a time harmony and poetry in basic research. Maybe,  with luck,  man will  see the value in the model  that basic research scientist use and incorporate  it into the  rest of his enterprises.

The conduct of the world from the beginning has been iffy. At times  filled  to the brim with violence,  breaking  the basic rules of conduct, commandments, civil, criminal laws, and advertisement practices giving us a world of leaders not qualified  to lead.. Government, business, and religion all   seem to be at each others throats while using the discoveries of this most unique tiny basic scientific research  community  to the disadvantage and advantage of its citizens.
