"The Nobel Duel" details the intense rivalry between two giants of 20th-century physics: Robert Millikan and Felix Ehrenhaft. Their decades-long feud centered on the fundamental nature of electric charge. Millikan's meticulous oil-drop experiment seemingly proved the quantized nature of charge, earning him the Nobel Prize. Ehrenhaft, however, persistently challenged Millikan's results, claiming to have observed "subelectrons" carrying fractions of the elementary charge. The article portrays the scientific clash, highlighting the personalities and experimental methods of both physicists, while exploring the complexities of scientific validation and the potential for bias in interpreting experimental data. Ultimately, Millikan's view prevailed, solidifying the concept of the elementary charge as a fundamental constant in physics.
The CERN Courier article "Beyond Bohr and Einstein" discusses the ongoing quest to understand the foundations of quantum mechanics, nearly a century after the famous Bohr-Einstein debates. While acknowledging the undeniable success of quantum theory in predicting experimental outcomes, the article highlights persistent conceptual challenges, particularly regarding the nature of measurement and the role of the observer. It explores alternative interpretations, such as QBism and the Many-Worlds Interpretation, which attempt to address these foundational issues by moving beyond the traditional Copenhagen interpretation championed by Bohr. The article emphasizes that these alternative interpretations, though offering fresh perspectives, still face their own conceptual difficulties and haven't yet led to experimentally testable predictions that could distinguish them from established quantum theory. Ultimately, the piece suggests that the search for a complete and intuitively satisfying understanding of quantum mechanics remains an open and active area of research.
HN commenters discuss interpretations of quantum mechanics beyond the Bohr-Einstein debates, focusing on the limitations of the Copenhagen interpretation and the search for a more intuitive or complete picture. Several express interest in alternatives like pilot-wave theory and QBism, appreciating their deterministic nature or subjective approach to probability. Some question the practical implications of these interpretations, wondering if they offer any predictive power beyond the standard model. Others emphasize the philosophical importance of exploring these foundational questions, even if they don't lead to immediate technological advancements. The role of measurement and the observer is a recurring theme, with some arguing that decoherence provides a satisfactory explanation within the existing framework.
Ruth Belville, known as the "Greenwich Time Lady," carried on her father's unique business of selling the precise time to Londoners from 1892 to 1940. She would synchronize her pocket watch, nicknamed "Arnold," to the Greenwich Mean Time clock at the Royal Observatory and then visit her clients, mostly jewelers and businesses, charging them a small fee for the accurate time. Though the advent of radio time signals presented competition, Belville continued her service, valued for her reliability and personal touch, until the outbreak of WWII. Her meticulous timekeeping method and long-standing tradition represented a bridge between astronomical observation and personal timekeeping in a rapidly changing world.

A few users shared further historical context, pointing out other instances of time being a commodity or highlighting the transition to standardized timekeeping. Several commenters also lamented the loss of such quirky, individualistic businesses in the modern era.
Bell Labs' success stemmed from a unique combination of factors. A long-term, profit-agnostic research focus fostered by monopoly status allowed scientists to pursue fundamental questions driven by curiosity rather than immediate market needs. This environment attracted top talent, creating a dense network of experts across disciplines who could cross-pollinate ideas and tackle complex problems collaboratively. Management understood the value of undirected exploration and provided researchers with the freedom, resources, and stability to pursue ambitious, long-term projects, leading to groundbreaking discoveries that often had unforeseen applications. This "patient capital" approach, coupled with a culture valuing deep theoretical understanding, distinguished Bell Labs and enabled its prolific innovation.
Hacker News users discuss factors contributing to Bell Labs' success, including a culture of deep focus and exploration without pressure for immediate results, fostered by stable monopoly profits. Some suggest that the "right questions" arose organically from a combination of brilliant minds, ample resources, and freedom to pursue curiosity-driven research. Several commenters point out that the environment was unique and difficult to replicate today, particularly the long-term, patient funding model. The lack of modern distractions and a collaborative, interdisciplinary environment are also cited as key elements. Some skepticism is expressed about romanticizing the past, with suggestions that Bell Labs' output was partly due to sheer volume of research and not all "right questions" led to breakthroughs. Finally, the importance of dedicated, long-term teams focusing on fundamental problems is highlighted as a key takeaway.

A 1923 paper by John Slater, a young American physicist, introduced the idea of a virtual radiation field to explain light-matter interactions, suggesting a wave-like nature for electrons. While initially embraced by Bohr, Kramers, and Slater as a potential challenge to Einstein's light quanta, subsequent experiments by Bothe and Geiger, and Compton and Simon, disproved the theory's central tenet: the lack of energy-momentum conservation in individual atomic processes. Although ultimately wrong, the BKS theory, as it became known, stimulated crucial discussions and further research, including important contributions from Born, Heisenberg, and Jordan that advanced the development of matrix mechanics, a key component of modern quantum theory. The BKS theory's failure also solidified the concept of light quanta and underscored the importance of energy-momentum conservation, paving the way for a more complete understanding of quantum mechanics.
HN commenters discuss the historical context of the article, pointing out that "getting it wrong" is a normal part of scientific progress and shouldn't diminish Bohr's contributions.
