Very enjoyable short read. Almost as soon as Oppenheimer Trinity test was a success, Leslie Groves drove him out, revoked his security clearance, called him a communist and he suffered greatly as a result. Oppenheimer lost many of his friends and his career. Because he was portrayed as a communist he found it difficult to get a job or even get invited to conferences. A very sad end for such a great man. One can only gaze in awe at his career, his accomplishments. He even made an important contribution to General Relativity with Harvard graduate student Ryan Snyder that a collapsing star would indeed form a black hole according to GR. Whatever else could be said of him, He certainly fulfilled his Dharma.
