Reviews of Modern Physics

• 1. Introduction

  ›

  Reviews of Modern Physics, known by the abbreviation RMP, launched in 1929 with a clear sense of purpose: to fill a gap that no other journal had filled. Physics was changing fast, and researchers needed a place where the entire sweep of a field could be laid out clearly. What made RMP unusual was its intended audience. It was not written only for specialists. University students, high school instructors, and curious members of the public were all part of the readership from the start.

  Some of its most celebrated papers carry names that echo through the history of science: Hans Bethe, Enrico Fermi, Subrahmanyan Chandrasekhar. Over the decades, its editors included a co-discoverer of quantum spin and a member of the Manhattan Project. And the journal did not confine itself to abstract theory. At different points it weighed in on the safety of light-water nuclear reactors, the feasibility of missile defense, and the structure of DNA.

  How did a quarterly journal become one of the most prestigious of its kind? And what choices, made by a small group of editors over nearly a century, shaped what physicists read and wrote?

• 2. An Unmet Need

  ›

  In 1929, the United States was in the process of displacing Germany as the world's leading nation for physics. English was replacing German as the dominant language of scientific communication. Against that backdrop, the American Physical Society launched RMP to serve a function nobody else was performing consistently.

  Review articles did exist before 1929. They were just published sporadically, with no dedicated home. RMP became the first journal of its kind, organized around the premise that the scientific community needed regular, systematic accounts of what had been learned in each branch of the field.

  The early editorial philosophy was conservative. The focus rested on branches of physics already considered settled. Fields where researchers still argued, or where major questions remained open, were largely kept out. That caution defined the journal's first decades.

• 3. Editors Who Shaped the Journal

  ›

  John Torrence Tate served as the journal's first editor from 1929 to 1941, then again in 1947. During the intervening years, he worked on antisubmarine warfare during the Second World War, a detail that places him squarely in the practical emergency physics of that era.

  Samuel Goudsmit held the editorship from 1951 to 1957. Goudsmit was the co-discoverer of quantum spin, one of the foundational concepts in modern physics. Edward Condon, who ran the journal from 1951 to 1968, had been a member of the Manhattan Engineer District. Condon held a particular conviction about the purpose of review writing. He believed that composing a review article should be part of a graduate student's training and a standing obligation of every working physicist.

  The current editor-in-chief is Sujit Datta, described as a multidisciplinary scientist, a label that fits a journal whose scope has expanded well beyond any single subdiscipline.

• 4. Crisis and Expansion

  ›

  By the 1950s and 1960s, something had gone wrong. Readership was falling. The editorial board faced a choice about whether to keep the journal focused on settled ground or to open it up.

  The board chose to expand. Topics at the frontier of research, where controversies were alive and major questions unresolved, were now welcome. That shift reversed the founding philosophy and aligned the journal with the way physics was actually being practiced.

  Edward Condon's years as editor, running from 1951 to 1968, overlapped almost entirely with this transition. His conviction that review writing was a scientific duty likely helped justify the expansion: if synthesizing knowledge was part of a physicist's responsibility, then frontier knowledge needed synthesizing too. Multiple authorship, a sign of increasingly collaborative science, became more frequent from the 1960s onward.

• 5. Landmark Papers

  ›

  Three papers by Hans Bethe on nuclear physics, published in 1936-7, rank among the most cited in the journal's history. Enrico Fermi contributed a paper on quantum electrodynamics in 1932. Subrahmanyan Chandrasekhar wrote on stochastic processes in astronomy and physics in 1943. Howard Percy Robertson addressed relativistic cosmology in 1931.

  Clemens Roothaan contributed two papers: one on molecular orbitals in 1951, and one on electronic systems in 1960. A 1956 paper on nuclear structure was co-authored by Kurt Alder, Aage Bohr, Torben Huus, Ben Mottelson, and Aage Winther. Several of the most cited authors in the journal later received Nobel Prizes.

  The institutional affiliations behind these papers trace a map of mid-twentieth-century physics: Bell Laboratories, the University of Chicago, the Argonne National Laboratory, the National Bureau of Standards (now called the National Institute of Standards and Technology), and the University of California campuses at Berkeley, Irvine, and San Diego. In the twenty-first century, papers on quantum foundations and the development of the Standard Model of particle physics have taken their place alongside those earlier landmarks.

• 6. Beyond the Laboratory

  ›

  RMP has occasionally published work aimed at audiences well outside professional physics. The journal addressed the safety of light-water nuclear reactors, a topic with obvious implications for public policy. It examined the feasibility of the Strategic Defense Initiative, the missile-defense program known as Star Wars. It also published work on the nature of the deoxyribonucleic acid molecule.

  Those choices reflect the journal's stated readership from the beginning: not only professional physicists, but university students, high school and university instructors, and scientifically literate members of the general public. The quarterly publication schedule, unhurried compared to weekly or monthly journals, suits the long-form synthesis that makes these broader interventions possible.

  Condon's view that physicists owe their community a clear account of what they know points toward the same ambition. A journal that publishes Fermi on quantum electrodynamics and also weighs in on missile defense is making a claim: that physics belongs, at least in part, to everyone who can follow an argument.
