So, what are the criteria of "scientifically valid" theses these days?
I would have preferred a statement like, "After discarding all parts which relied upon the fabricated data, the resulting thesis is still acceptable to the committee as a doctoral thesis." However, I feel bad about all the Ph.D.'s out there who may feel they have to defend the integrity of their work. (Mine is in pure math; fabricated data is not a big worry for us :D )
