It is well known that the progress of science is related to social processes. Thomas Kuhn and the work based on him made this pretty clear. I would go a step further and declare that “Science progresses through the death of its professors”. I am not sure if this is a novel thought, maybe it is just a radicalization of Kuhn’s thoughts. I certainly do not want to encourage anyone to kill professors (being one myself), but I do think that the senior researchers do inhibit change. Maybe when I am a bit older I will see the benefit in it.
