Math Files(@Math_files):On the left is Niels Bohr, one of the pioneers of quantum mechanics. On the right is Albert Einstein, known for his theory of relativity. This photograph was taken in December 1925 at the home of physicist Paul Ehrenfest in Leiden. Einstein disagreed with the probabilistic nature of quantum theory and famously said, “God does not play dice.” Bohr responded, “Einstein, stop telling God what to do.” Their disagreement became one of the most important debates in the history of physics. Although they strongly disagreed, they respected each other and continued to engage seriously with each other’s ideas.
