by Jacob Aron Where’s a scientific genius when you need one? A statistical analysis suggests that Isaac Newton saved the UK economy the equivalent of millions of pounds by implementing measures tostandardise the country’s gold coins. Although Newton is famous for his theory of gravity, he also spent the last 30 years of his life… [Read more…]
Art Hobson Quantum foundations are still unsettled, with harmful effects on science and society. By now it should be possible to obtain consensus on at least one issue: Are the fundamental constituents fields or particles? Experiment and theory imply a universe made of unbounded fields rather than bounded particles. This is especially clear for relativistic… [Read more…]
Helge Kragh Ideological considerations have always influenced science, but rarely as directly and massively as in the Soviet Union during the early Cold War period. Cosmology was among the sciences that became heavily politicized and forced to conform to the doctrines of Marxism-Leninism. This field of science developed entirely differently in the Communist countries than… [Read more…]
John P. Ralston Planck’s constant was introduced as a fundamental scale in the early history of quantum mechanics. We find a modern approach where Planck’s constant is absent: it is unobservable except as a constant of human convention. Despite long reference to experiment, review shows that Planck’s constant cannot be obtained from the data of… [Read more…]
Despite the success of physics in formulating mathematical theories that can predict the outcome of experiments, we have made remarkably little progress towards answering some of the most basic questions about our existence, such as: why does the universe exist? Why is the universe apparently fine-tuned to be able to support life? Why are the… [Read more…]

Aux yeux de tous, Newton est… [Read more…]

John H. Schwarz This lecture presents a brief overview of the early history of string theory and supersymmetry. It describes how the S-matrix theory program for understanding the strong nuclear force evolved into superstring theory, which is a promising framework for constructing a unified quantum theory of all forces including gravity. The period covered begins… [Read more…]
Luke A. Barnes The fine-tuning of the universe for intelligent life has received a great deal of attention in recent years, both in the philosophical and scientific literature. The claim is that in the space of possible physical laws, parameters and initial conditions, the set that permits the evolution of intelligent life is very small.… [Read more…]
W.-D. Schlatter (CERN), P. M. Zerwas (DESY) After a brief introduction to the theoretical basis of the Higgs mechanism for generating the masses of elementary particles, the experimental searches for Higgs particles will be summarized, from bounds at LEP to inferences for LHC. The report will focus on the Standard Model, though some central results… [Read more…]
Danny Hillis, Rob Seaman, Steve Allen, Jon Giorgini The Long Now Foundation is building a mechanical clock that is designed to keep time for the next 10,000 years. The clock maintains its long-term accuracy by synchronizing to the Sun. The 10,000-Year Clock keeps track of five different types of time: Pendulum Time, Uncorrected Solar Time,… [Read more…]

Philosophy and problems of the definition of Extraterrestrial Life Jean Schneider Abstract When we try to search for extraterrestrial life and intelligence, we have to follow some guidelines. The first step is to clarify what is to be meant by “Life” and “intelligence”, i.e. an attempt to define these words. The word “definition” refers to… [Read more…]
Helge Kragh By 1930, at a time when the new physics based on relativity and quantum theory had reached a state of consolidation, problems of a foundational kind began to abound. Physicists began to speak of a new “crisis” and envisage a forthcoming “revolution” of a scale similar to the one in the mid-1920s. The… [Read more…]
…. “German Scientists for the Preservation of Pure Science,” Relativity, and the Bad Nauheim Meeting Jeroen van Dongen Two important and unpleasant events occurred in Albert Einstein’s life in 1920: That August an antirelativity rally was held in the large auditorium of the Berlin Philharmonic, and a few weeks later Einstein was drawn into a… [Read more…]
Search engine honours Nobel prize-winning scientist who was renowned for her pioneering work on radioactivity The birth of Nobel prize-winning scientist Marie Curie has being marked by Google with a picture of her at her work bench on the search engine’s home page. The Polish-born physicist and chemist is renowned for her pioneering work on… [Read more…]
Ancient tales of Norse mariners using mysterious sunstones to navigate the ocean when clouds obscured the Sun and stars are more than just legend, according to a study published Wednesday. Over 1,000 years ago, before the invention of the compass, Vikings ventured thousands of kilometres from home toward Iceland and Greenland, and most likely as… [Read more…]
….reveals insights centuries ahead of its time Thirteenth-century manuscript, overwritten with prayer book, deciphered after years of painstaking work Years of painstaking work by scientists to expose a manuscript hidden for nearly a thousand years have shed new light on the genius of Archimedes, antiquity’s greatest mathematician. Known as The Archimedes Palimpsest, the manuscript is… [Read more…]
The Universe wouldn’t be the same without the Higgs boson. This legendary particle plays a role in cosmology and reveals the possible existence of another closely related particle. The race to identify the Higgs boson is on at CERN. This Holy Grail of particle physics would help explain why the majority of elementary particles possess… [Read more…]
Who discovered that E = mc2? It’s not as easy a question as you might think. Scientists ranging from James Clerk Maxwell and Max von Laue to a string of now-obscure early 20th-century physicists have been proposed as the true discovers of the mass–energy equivalence now popularly credited to Einstein’s theory of special relativity. These… [Read more…]
In 1842, the first American author of tales of horror, Edgar Allen Poe (1809-1849) wrote a short story entitled, The Pit and the Pendulum. Poe’s stories often contained a strong element of terror, in part, because he left many of the details quite vague, just as a standard technique of psychological terror is to keep… [Read more…]
The Niels Bohr Library and Archives is pleased to announce that it has digitized the complete Samuel A. Goudsmit Papers (1921–1979, 30 linear feet, approximately 67,000 images). The Goudsmit Papers are a major international collection of correspondence, research notebooks, reports, World War II science documents, and other material of Goudsmit, a Dutch physicist who spent most of… [Read more…]
Originally published in the Manchester Guardian on 12 August 1930 It would seem all doubts as to the existence of the new planet announced from the Lowell Observatory in March last have been set at rest. Fifteen years ago the late Dr. Percival Lowell published his “Memoir on a Trans Neptunian Planet,” in which he… [Read more…]
It is generally supposed that the time order in which discoveries are made should have no eventual influence on our beliefs. But it is very evident that they do, and perhaps nowhere more importantly than with the cosmic microwave background. The cosmic microwave background first showed itself observationally to astronomers in the late 1930s and… [Read more…]
THE CURIOUS CASE OF LEMAÎTRE’S EQUATION NO. 24 Sidney van den Bergh In August of 1961 Abbé Georges Lemaître told me (with a twinkle in his eyes) that, being a priest, he felt a slight bias in favor of the idea that the Universe had been created. It must therefore have been a particular pleasure… [Read more…]
It would be hard to imagine a more intelligent and brilliant group of people, let alone all these great minds in the same room together. However this was the case in 1927 when Einstein and his venerable colleagues gathered at the Solvay Conference on Electrons and Photons in Brussels. The International Solvay Institutes for Physics… [Read more…]
