How famous ?

Slightly less famous than it would take for me to have ever heard of him.

 

Well...I've honestly never heard of him, lol. Who is he????

 

Apparently he wrote a book: http://scipp.ucsc.edu/~dine/
So is the question related to this?

 

Is he your professor or something?

 

I think he is rather known within the string community. I have heard his name a few times, through some of my more "stringy" colleagues and because of a course in supersymmetry.
