125 years ago, 36 physicists gathered at Columbia University with a common goal: to advance and diffuse the knowledge of physics. And just like that, the American Physical Society was born. Since then, we’ve been the professional home for some of the greatest minds in physics and beyond, published the most Nobel Prize-winning physics papers globally, and convened 30,000 researchers annually to debate with and gain inspiration from one another. Now, we’re looking to the next 125 years and strivin
