It is impossible to make real progress in technology without gambling. - Freeman Dyson

He aquí cómo describía la situación el propio Einstein: Cuando estaba en el séptimo grado en el Luitpold Gymnasium de Múnich, fui convocado por mi tutor, que me expresó el deseo de que yo abandonara el centro. Al decirle yo que no había hecho nada malo, se limitó a contestar: «Su mera presencia hace que la clase me pierda el respeto». Einstein se alegró de poder ayudar al profesor.

In my opinion, the black hole is incomparably the most exciting and the most important consequence of general relativity. Black holes are the places in the universe where general relativity is decisive. But Einstein never acknowledged his brainchild. Einstein was not merely skeptical, he was actively hostile to the idea of black holes. He thought that the black hole solution was a blemish to be removed from his theory by a better mathematical formulation, not a consequence to be tested by observation. He never expressed the slightest enthusiasm for black holes, either as a concept or as a physical possibility. Oddly enough, Oppenheimer too in later life was uninterested in black holes, although in retrospect we can say that they were his most important contribution to science. The older Einstein and the older Oppenheimer were blind to the mathematical beauty of black holes, and indifferent to the question whether black boles actually exist.

How did this blindness and this indifference come about?

It is more difficult for a modern scientist to be a serious Christian, like Polkinghorne, than to be a serious Muslim, like the Nobel Prize-winning physicisit Abdus Salam. Salam happily proclaimed his Muslim faith but did not feel any need to write books about it. For Salam, the idea of a conflict between his faith and his science was ludicrous. Muslim faith has nothing to do with science. But Polkinghorne writes books to prove to himself and to us that his theology and his science can live together harmoniously..
