Thanks Dan — I look forward to PART II.

In the early 80’s a couple of us physicists asked Dan Freed (then Isadore Singer’s student) if the exotic R^4’s might have any relevance for physics and without going into details his answer was “no”. I’m now thinking I should have asked for those details.
Didn't Dan Freed write or coauthor a book about 4-manifolds? (Btw, as an undergrad, Singer was my favorite prof — I had him for three courses.) --Dan
