Those who are not shocked when they first come across quantum theory cannot possibly have understood it. ~ Neils Bohr

On his journey home from delivering his acceptance speech in Sweden the following summer, Einstein stopped in Copenhagen to see Bohr, who met him at the train station to take him home by streetcar. On the ride, they got into a debate. “We took the streetcar and talked so animatedly that we went much too far.” Neither seemed to mind, for the conversation was so engrossing. “We rode to and fro,” according to Bohr, “and I can well imagine what the people thought about us.”

More than just friendship, their relationship became in intellectual entanglement that began with divergent views about quantum mechanics then expanded into related issues of science, knowledge, and philosophy. “In all the history of human thought, there is no greater dialogue than that which took place over the years between greater dialogue than that which took place over the years between Niels Bohr and Albert Einstein about the meaning of the quantum,” says the physicist John Wheeler, who studied under Bohr. The social philosopher C.P. Snow went further. “No more profound intellectual debate has ever been conducted,” he proclaimed.

Their dispute went to the fundamental heart of the design of the cosmos: Was there an objective reality that existed whether or not we could ever observe it? Were there laws that restored strict causality to phenomena that seemed inherently random? Was everything in the universe predetermined?

For the rest of their lives, Bohr would sputter and fret at his repeated failures to convert Einstein to quantum mechanics. ‘Einstein, Einstein, Einstein,’ he would mutter after such infuriating encounter. But it was a discussion that was conducted with deep affection and even great humor. On one of the many occasions when Einstein declared that God would not play dice, it was Bohr who countered with the famous rejoinder: Einstein, stop telling God what to do! ~ Pages 325 & 326 {Einstein - His Life & Universe by Walter Issacson}

Bohr worked on this theory (The single system has two simultaneous modes of description, one not reducible to the other) for six months and first outlined it in his 1927 Como Lecture, presented to an illustrious group of physicists at the congress commemorative of the one-hundred-year anniversary of death of Alessandro Volta en.wikipedia.org/wiki/Alessandro_Volta Einstein wasn’t there and didn’t hear it until next month, when Bohr presented it again in Brussels. Einstein was unhappy with the idea of a dual description and uncertainty. He and Bohr began a lengthy exchange that lasted years. Einstein would come up with a scenario in an attempt to defeat quantum theory, only to have Bohr present an argument consistent with quantum theory that overcame it. Since then, many proposals have been made and experiments done attempting to bolster Einstein’s side of the debate; all have been unsuccessful. While unpopular among those with a determinist bias, a version of Bohr’s complementarity remains undefeated. ` Page 172
