From Is it appropriate (as a PhD student) to email other researchers asking about some details in their papers?, I get that generally you will get answer if you ask question on their work. But what if your question is tangent to their work, and requires some space to elaborate?
The draft is below:
Dear Prof X
To introduce myself, my name is Y, from country Z. I have read some pages in your book about the connection between [concept A in field 1] and [concept B in field 2]. I wonder what do you think about the connection between [concept C in field 1] and [concept D in field 2]?
[16 lines and 184 words to elaborate the connection. I don't consider this as a wall of text]
I also have a blog article explaining all my observations about the connection between field 1 and field 2. It may take only 5 minutes to read.
Thank you for your reading. Hope you enjoy it.
- I haven't read his book enough to say that I know a large portion of it (just skimming it), but I can say that I understand A, B, C, D at least in introductory level.
- I don't have any institute, but I think my culture is relevant to field 1, so perhaps it can be a kind of expertise/institute?
- I may apply to his school in the future
