  • Essay On Dark Matter

    Dark matter leaves astronomers and physicists baffled as to what it possibly could be. Scientists design experiments to attempt to figure out what it is, but no one truly knows what composes dark matter. Physicists are so interested in understanding dark matter because it accounts for the formation of the Universe, as observable through studying the distribution of gravity within galaxies (Carnegie). Original attempts at studying dark matter referred to dark matter as baryonic, which is a word used to describe baryons, or quark based particles. Quarks make up “normal” subatomic particles, and so when referring to dark matter as baryonic, physicists were assuming that dark matter was made up of protons, electrons, and neutrons, just like all types of known matter, yet that would infer that we would be able to observe dark matter through telescopes. In the 1970s, astrophysicists and astronomers thought browns dwarves could be composed of dark matter (Arguelles et…

    universe. They used the world 's largest and most complex scientific instruments to study the basic constituents of matter – the fundamental particles. On 4 July 2012, CERN and Collaborative companies, experiment at Large Hadron Collider announced they had each observed a new particle. This particle is called the Higgs boson predicted by the Standard Model. The Higgs boson, as proposed that this particle is the simplest manifestation of the Brout-Englert-Higgs mechanism, which is The basic…

  • Technology In Particle Fever

    science that does not have an immediate benefit in everyday lives is often seen as less important. In the movie, Particle Fever (2013), Mark Levinson delves into the world of science and the creation of the Large Hadron Collider (LHC). The United States government halted the production of a similar version of the LHC because they found no immediate benefits from this experiment. They deemed money to be spent on more practical applications such as funding the military, schools, or healthcare…

    grain-machine interaction systems responses where the micro parameters in DEM models are developed using particle-particle friction, particle-geometry friction and the particle density to simulate material behavior (Asaf et al., 2007). The particle size and shape distribution are also considered to be input DEM parameters. In DEM, spherical particles are usually preferred because of the efficiency of contact detection. However, when using this type of particles, the bulk friction of the assembly…

  • Quasiclassical Elienberger Equations

    Quasiclassical Elienberger equations [129] for the green functions g(k , r, and order parameter , is a powerful tool to deal with inhomogeneous superconductors [130]. These functions depend on the so called, ‘Matsubara frequency’, , coordinate r, and wave vector k on the fermi surface. The dependence of green functions and order parameters on the wave vector k, makes them sensitive to the shape of fermi surface. This makes solution of Elienberger equations complicated in the system of complex…

    be easily modified to include Monte Carlo estimation of the constant coefficients. We recall that the standard particle filtering method suffers from weight degeneracy especially when the estimation includes static parameters. EnKF, however, does not suffer from degeneracy and provides a good estimate of the coefficients by integrating a sample minimum mean square estimate (MMSE) of the coefficients within the EnKF algorithm. Without loss of generality, let us consider a first-order wide-sense…

    many short-lived particles within the nucleus. However, these could only be seen in tracks left behind in sensitive detectors. There were many particles found such as muon, which behaves like and electron and is 210 times heavier. There is also the pion which is a little smaller than the muon as well as the kaon, which is just over half the mass of a proton, and finally the lambda, which is 20% heavier…

  • If The Super-Symmetry Theory Is Valid?

    Fig: Schematic representation of LHC and it's detectors The primary objective of LHC is to answer the following questions: 1. Why some particles are heavier than others? If the Higgs mechanism is valid? 2. If the super-symmetry theory is valid? If yes then if super-symmetric particles exist? 3. If the concept of dark matter and dark energy correct? 4. Why our universe is made up of matter only? 5. What was the state of matter in the early universe? 6. What will be the properties…
