DiracPool said:Well, yeah..Ok. My point was more of the idea of revolutionizing a field, which I think the topic of the thread is. Of course if you're baking a cake and I'm mixing the drinks I'm not going to make a better cake than you, but I may recognize when I come visit your station that somehow you got so used to using margarine because of the war rationing that we are now actually allowed to use butter since the war is over, etc.
In any case, I didn't come up with the outsider changes the game idea, that was Kuhn. He made this argument in Structures of scientific revolutions. My main point is not that it has to be someone outside a certain discipline per se that has to make the big breakthrough, it is more as I said in my earlier post that one has a certain WINDOW where they can make that breakthrough, a window whereby their conceptual understanding of a situation is chaotic enough that the attractor in the brain doesn't fall in easily to some pre-learned limit cycle solution. Does that make sense?
So, it doesn't have to be someone from another field, just someone who hasn't spent their careers learning only the status quo. Maybe Planck and a few others are exceptions, but Guys like Einstein, Dirac, and Heisenberg were young enough to keep those attractos chaotic, and guys like Newton and Galilleo had the benefit of not having a stringent scientific load to memorize before they came up with their great works.
People like Einstein, Dirac and Heisenberg all had PhD's in physics. So they weren't outsiders. They knew extremely well what the "status quo" was.
You say that an outsider, like a neuroscientist, can make discoveries in physics. If this is true, then you must give examples. Because, as far as I know, practically all discoveries in physics were done by practicing physicists which were familiar with the field. I have never heard of a PhD in neuroscience (or similar) making discoveries in physics without taking out years to study the physics.
