Here’s what Einstein meant when he spoke of cosmic dice and the “secrets of the Ancient One”.

• To celebrate Einstein’s birthday this past Sunday (14 de mars de 1879), we examine his take on religion and spirituality.
• Einstein’s disapproval of quantum physics revealed his discontent with a world without causal harmony at its deepest levels: The famous “God does not play dice.”
• He embraced a “Spinozan God,” a deity that was one with nature, within all that is, from cosmic dust to humans. Science, to Einstein, was a conduit to reveal at least part of this mysterious connection, whose deeper secrets were to remain elusive.

Given that March 14th is Einstein’s birthday and, in an uncanny coincidence, also Pi Day, I think it’s appropriate that we celebrate it here at 13.8 by revisiting his relationship with religion and spirituality. Much has been written about Einstein and God. Was the great scientist religious? What did he believe in? What was God to Einstein? In what is perhaps his most famous remark involving God, Einstein expressed his dissatisfaction with the randomness in quantum physics: he “God doesn’t play dice” quote. The actual phrasing, from a letter Einstein wrote to his friend and colleague Max Born, dated December 4, 1926, is very revealing of his worldview:

Quantum mechanics is very worthy of regard. But an inner voice tells me that this is not the true Jacob. The theory yields much, but it hardly brings us close to the secrets of the Ancient One. In any case, I am convinced that He does not play dice.
