    A cornerstone of physics may require a rethink if findings at the National Institute of Standards and Technology (NIST) are confirmed. Recent experiments suggest that the most rigorous predictions based on the fundamental theory of electromagnetism—one of the four fundamental forces in the universe, and harnessed in all electronic devices—may not accurately account for the behavior of atoms in exotic, highly charged states. The theory in question is known as quantum electrodynamics, or QED, which physicists have held in high regard for decades because of its excellent track record describing electromagnetism's effects on matter. In particular, QED has been especially...

    Nobel Prize-winning and eccentric physicist Richard Feynman has been called a buffoon and a magician, but is lauded as a man who could make science accessible and interesting for all. When I was a child I desperately wanted to be a scientist, but then it all went wrong. Unfortunately, during the early years of my secondary school education, science became joyless. It was a subject that seemed disjointed from the world even though it is the method that attempts to explain the world and the universe. If only it were possible to place an automaton Richard Feynman in every school....

    RICHARD FEYNMAN, Nobel laureate and physicist extraordinaire, called it a “magic number” and its value “one of the greatest damn mysteries of physics”. The number he was referring to, which goes by the symbol alpha and the rather more long-winded name of the fine-structure constant, is magic indeed. If it were a mere 4% bigger or smaller than it is, stars would not be able to sustain the nuclear reactions that synthesise carbon and oxygen atoms. One consequence would be that squishy, carbon-based life would not exist. Why alpha takes on the precise value it does, so delicately fine-tuned for...
  • The Difference between ‘True Science’ and ‘Cargo-Cult Science’

    “Science is the belief in the ignorance of experts” is how the great Nobel Prize-winning physicist Richard Feynman defined science. “Science is the belief in the ignorance of experts” is how the great Nobel Prize-winning physicist Richard Feynman defined science in his article “What is Science?” Feynman emphasized this definition by repeating it in a stand-alone sentence in extra large typeface in his article.  (Feynman’s essay is available online, but behind a subscription wall: The Physics Teacher (1969) volume 7, starting page 313.)Immediately after his definition of science, Feynman wrote: “When someone says, ‘Science teaches such and such,’ he is...

    It was at Caltech that Gell-Mann helped to lay the foundations for our understanding of the components that make up matter. He drafted a blueprint of subatomic physics that he called the Eightfold Way. At the time, physicists understood that atoms are constructed from protons and neutrons, but they had also found many other mysterious particles. The Eightfold Way made sense of this baffling menagerie, finding within it places for particles never even imagined. The work was so important that it netted Gell-Mann a Nobel Prize in 1969. In 1984 Gell-Mann pursued his dream of working in other fields by...
