Query: HARDCORE SCI-FI

This book pulled me out of a thinking dry spell and got my imagination working again...however, as far as a story goes the book is somewhat weak, but don't let that stop you from reading it. It would be reaally interesting if Mr. Baxter would write a book called "Some Cool Ideas I Have and How They Might Work" and just cut the storyline altogether. All in all a book I'll remember ( i forget more books than i remember)
