A fascinating and terrifying look at the inextricable relationship between scientific discovery, particularly astrophysics and warfare and the difficult line that scientists walk when pursuing their research. A little overlong and dry in some sections.

The book itself was really good, and I would recommend it to people. But I simply didn’t like it. Great writing as always from Tyson.

This is a really interesting read.
"Accessory to War" is an engaging, well-researched examination of the intersection between science, technology, industry, and power. In addition to examining these connections, it's also a good book about (astro)physics. It's written in an accessible style. Definitely worth a read.

Neil deGrasse Tyson combines history and astronomy to expose the symbiotic relationship between astronomy/astrophysics and the military. Through a history of astronomy, he explores how and why political powers have funded space exploration, both physical and theoretical over the centuries. Eye-opening understanding of the use an misuse of scientific research.

This has got to be one of the worst books I have ever read. The authors clearly never had an original thought. The entire thesis is derivative and full of conspiracy theorist mentality. At the end, authors say they are 'separately and jointly grateful to the innumerable individuals and institutions whose writings, lectures, emails, conversations, fats, checks, critiques, queries, responses and resources enabled us to construct this book'.'

They are not kidding.

A very thorough look into the relationship between science and the military, and the advancements that relationship often brings. Some may find it a little too thorough, but for those who are at all interested in the subject this is a well informed and fascinating read.

For anyone interested in the linkage between the missions of science and warfighting, this book is for you. I feel like I can tell the pages written by Dr. Tyson, and those written by Avis Lang. That may sound negative, but it’s not. I think the humor and perspective of Dr. Tyson comes through more with the contrast. Anyone interested in the early days of space (both military and civil) should give this a read for a sort of intro to the subject. That aside, the book doesn’t paint a poignant picture of the military as I expected. It’s not pro-war, and not 100% anti-military either. Unless you are Aunt Melissa, that is. Overall a good read that I felt compelled to read whenever I had time to do so. Will buy this when out in paperback to have at home for sure.
