• What is Cerenkov Radiation?

    …the creative principle resides in mathematics. In a certain sense therefore, I hold it true that pure thought can grasp reality, as the ancients dreamed.Albert Einstein Many do not recognize the process that unfolds in the developing perspectives about theoretics? Does one think it is divorced from reality that you could say, “hey this idea…

  • From Modelling to Experimentation?

    Moving to higher energies, the expected fluxes of neutrinos become smaller, that even a cubic kilometer detector is not able to detect them. Larger volumes can be achieved by replacing optical sensors by acoustic detection. The reason is that acoustic waves can propagate over larger distances than light and allow wide spacing of detectors, and…

  • The Periodic Table of the Moon’s Strata

    Clementine color ratio composite image of Aristarchus Crater on the Moon. This 42 km diameter crater is located on the corner of the Aristarchus plateau, at 24 N, 47 W. Ejecta from the plateau is visible as the blue material at the upper left (northwest), while material excavated from the Oceanus Procellarum area is the…

  • Catching Nature in Action

    To capture the particles emerging from powerful proton-proton collisions at the LHC, scientists design and build huge, massive detectors. The CMS detector, about 50 feet tall, relies on an array of particle detection subsystems. The tracker (the subsystem at its core) records particle tracks with ultrahigh precision. The intermediate subsystem, the calorime-ter, determines the energy…

  • Quest For Convincing Evidence?

    THE BEVALAC IN WHICH IONS OF HEAVY ELEMENTS, CREATED IN THE SUPERHILAC (TOP), WERE SENT DOWN A BEAM PIPE FOR FURTHER ACCELERATION AND EXPERIMENTAL WORK IN THE BEVATRON WHEN NUCLEI COLLIDE AND THE ENERGY DENSITY OF THE PARTICLES PRODUCED IS SUFFICIENTLY HIGH, THEN A QUARK-GLUON PLASMA COULD BE PRODUCED Dialogos of Eide

  • Historical Approach of the Sand Reckoner

    I should pave the way for how the thoughts that are unfolding this morning. But nothing afflicted Marcellus so much as the death of Archimedes, who was then, as fate would have it, intent upon working out some problem by a diagram, and having fixed his mind alike and his eyes upon the subject of…

  • Cosmic Rays in Atlas

    Like Piglet describing the Heffalump in Winnie the Pooh by AA Milne, one knows this started out in some fantastical world. More then, the “inkblot” as a comparison leads too/from, a fictional story, and became the fantasy of Alice that had already been mathematically set in motion? So, theree are “ground rules” on using the…

  • Gravitational Radiation

    How dry this article in comparison to what we can witness in the cosmo? One gets this sense of “curvature implied” that the events connected at locations in the universe could have been felt in other locations? What connects them? The spacetime fabric?:) If one was speaking and one was seeing beyond the observation of…

  • Gravity-Don’t Let it Get You Down

    If a inkblot appears on your desk, would you think it appeared in the shape it did to convince you, that what you are “seeing is real?” To you, it may look like someone trying in their attempts to convince you of what a blackhole is? These questions greatly disturbed Richard Feynman. His famous paper…

  • Why do physicists want to study particles?

    A few “cosmic rays” pass through our body every second of every day, regardless of where we are. They consist of particles created when high energy atomic nuclei (mainly protons) coming from outer space collide with the atoms at the top of the earth’s atmosphere. Such particles are not just electrons, protons and neutrons, but…

  • A Distorted Lense?

    Gravity dominates the large-scale structure of the universe, but only by default, so to speak. Matter arranges itself to cancel electromagnetism, and the strong and weak forces are intrinsically short range. At a more fundamental level, gravity is extravagantly feeble. Acting between protons, gravitational attraction is about 10-36 times weaker than electrical repulsion. Where does…
