BurntSynapse, Please define Nersessian's "concrete problem"
Suggesting either "I think..." or..."a question from godless dave"
...is evidence.
Reading comprehension does not seem to be a strength,
BurntSynapse 
.
There are 2 sentences in that post by
godless dave:
*
The (suggestion for) evidence: "I think the history of physics, chemistry, and biology research supports it."
*
The question: Were Einstein, Bohr, Heisenberg, Curie, Wallace, and Darwin motivated by concrete problems?
The proper response to the question is something like:
* Nersessian's "concrete problem" is defined as ...
* Thus X, Y and Z were motivated by Nersessian's "concrete problem" as in these citations ...
Where is the assertion that problem-solving was not involved in some particular research,
BurntSynapse?
godless dave is stating the obvious - that theoretical scientists are not primarily motivated by your undefined "concrete problems". They are motivated by a wish to expand the frontiers of science or to fix gaps in theory.
I will emphasize the point you missed,
BurntSynapse :
You still have no citation about or definition of Nersessian's "concrete problem".
And
ETA: Looks like your reply was close to gibberish.
"Model-Based Reasoning in Scientific Discovery" has Nersessian writing
Actually that should be your assertion about Nersessian's "concrete problem" looks like gibberish

.
Einstein stating that he was motivated by theoretical rather than your
undefined Nersessian's "concrete problem":
"I only began to wonder about space and time when I was already grown up. In consequence I probed deeper into the problem than an ordinary child would have done."
Rutherford being motivated by theory than your
undefined Nersessian's "concrete problem":
"Rutherford, who had a few years earlier, discovered the planetary model of the atom asked Bohr to work on it because there were some problems with the model."
Curie was actually motivated by experiments (not your
undefined Nersessian's "concrete problem").
Wallace and Darwin were not motivated by your
undefined Nersessian's "concrete problem".
