Rev, my boss has this book in his office. He's intrigued by Ramanujan. He visits India frequently and a few times Ramanujan's home in Tamil Nadu. He said it's like a tourist attraction and all the taxi drivers know the address. I've read bits and pieces but will try to read it in its entirety.
When you get some free time---check out this video on Ramanujan---you may want to share it with your boss----go ahead and read the book.
