It's an experience like no other experience I can describe, the best thing that can happen to a scientist, realizing that something that has happened in his or her mind exactly corresponds to something that happens in nature. One is surprised that a construct of one's own mind can actually be realised in the honest-to-goodness world out there. A great shock, and a great, great joy.
Today when the public thinks of the products of science it is likely to think about environmental problems, an unproductive armament industry, careless or dishonest 'scientific' reports, Livermore cheers for 'nukes forever' and a huge amount of self-serving noise on every subject from global warming to 'the face of God'.
Science is in low regard.
We are fast approaching a situation in which nobody will believe anything we [physicists] say in any matter that touches upon our self-interest. Nothing we do is likely to arrest our decline in numbers, support or social value.
