Im not talking about using it to validate anything about the claims on whether it works or not which I dont believe it even comments on Im talking about using it for the history of the product how Patterson took it to CETI and all of the other related history in regards to that The most that could possibly be used in terms of the physics it somewhat discusses would be that it is a secondary source putting forth Pattersons claims but even then I wouldnt want to use it for that Just the history is good enough
