This marked the first of two meetings that took place in Leiden, with the second taking place just a year later in 1922. During their time in Leiden, these two giants of physics discussed their various theories and research, with a particular focus on Einstein’s Theory of Relativity and Lorentz’s work on the Electromagnetic Field Theory. It was these conversations that ultimately led Einstein to make some of his most important … Theoretical physicists, Albert Einstein and Hendrik Lorentz in Leiden, 1921. részletei…
