One considering work produced by Schrodinger in part (3,7)
I believe the answer is:
the thinker
'one considering work produced by schrodinger in part' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'one considering work produced by' is the wordplay.
'one' becomes 'the' (both can introduce a definite example of something).
'considering work' becomes 'thinker' (I can't explain this - if you can you should believe this answer much more).
'produced by' says to put letters next to each other.
'the'+'thinker'='THE THINKER'
Can you help me to learn more?
(Another definition for the thinker that I've seen is " Famous sculpture by Rodin".)
