Appearing in this IF Conversation, MIT history of science professor David Kaiser explains how a group of physicists, some of whom were trained at the nation's most prestigious institutions, found themselves on the counter-cultural margins of society at a time when our understanding of quantum physics was also undergoing a similarly profound change.
The mix was combustible. And it led to the kinds of questions that have always been characteristic of the success - and the failure, of course - of any number of transformative projects over time.
Kaiser's own field of particle cosmology certainly has no shortage of deep questions, some of which he mentions near the end of the video.
Did the members of the "Fundamental Fysiks Group" save physics? Doubtful. But I'm pretty sure they enjoyed it more.
It's just a guess.
