Dialogos of Eide/Home

  • See 21-23 January 2013 CERN

    The primary goal of this 3‐day workshop is to educate the LHC community about the scientific utility of likelihoods. We shall do so by describing and discussing several real‐world examples of the use of likelihoods, including a one‐day in‐depth examination of likelihoods in the Higgs boson studies by ATLAS and CMS. The workshop will start…

  • Spintronics made easy

    Spintronics (a neologism for “spin-based electronics”), also known as magnetoelectronics, is an emerging technology which exploits the quantum spin states of electrons as well as making use of their charge state. The electron spin itself is manifested as a two state magnetic energy system. The discovery of giant magnetoresistance in 1988 by Albert Fert et…

  • Olfactory Experience

    Ifyou sprinkle fine sand uniformly over a drumhead and then make itvibrate, the grains of sand will collect in characteristic spots andfigures, called Chladni patterns. These patterns reveal muchinformationabout the size and the shape of the drum and the elasticity of itsmembrane. In particular, the distribution of spots depends not only onthe way the drum…

  • Quantum Foam and Discrete Measures

    Physicists would dearly love to study this foam but there’s a problem. Spacetime only becomes foam-like on the tiniest scale, at so-called Planck lengths of 10^-35 metres or so. See: How to Measure Quantum Foam With a Tabletop Experiment An ongoing question was raised by Bee of Backreaction and thoughts I have had as to…

  • Abell 399 and Abell 401, connected by a bridge of hot gas

    This image shows galaxy clusters Abell 399, lower center, and Abell 401 connected by a bridge of hot gas (ESA Planck Collaboration / STScI Digitized Sky Survey)  Planck’s primary task is to capture the most ancient light of the cosmos. If this faint light interacts with the hot gas permeating different types of space structures…
