Quantum chromodynamics

The theory of the strong interaction force -- Quantum Chromodynamics (QCD) -- predicts that at sufficient high temperature and/or baryon density, nuclear matter undergoes a phase transition from hadrons to a new state of the deconfined quarks and gluons: the quark gluon plasma (QGP)~\cite{Bjorken:1982qr}. Over the past two decades, ultra-relativistic heavy-ion collision experiments at the Relativistic Heavy Ion Collider (RHIC) and the Large Hadron Collider (LHC) have been searching and exploring

in studying collective flow and particle correlations in AA collisions, and have made several original contributions. Motivated by a conjectured universal lower bound of $1/4\pi$ on the shear viscosity to entropy density ratio ($\eta$/s) for all quantum fluids from the string theory, one main theme of the field is to precisely determine the $\eta$/s value of the QGP fluid from measurements of collective flow and azimuthal correlations. In extracting the $\eta$/s value from data, theoretical modeling

Physics, Love, and Richard Feynman Introduction Physics. Love. These two words sum up the entities that Richard Feynman held most important throughout his entire life. An extraordinary individual, Feynman was able to combine an incredible mind with an incredible personality to achieve ends bordering on the magical. After Feynman's death in 1988, physicist Hans Bethe, paraphrasing the mathematician Mark Kac, spoke of two kinds of geniuses. He explained that the ordinary kind does great things

Daniel Craig’s new James Bond in Casino Royale breathes fresh life into what had become, in my opinion, a rather tired and worn out concept - a striking achievement, considering Casino Royale was Ian Fleming’s first novel in the series, written in 1953. We encounter Bond as a fledgling British agent, yet to gain MI6 double-0 Status, with its ‘licence to kill’. The film strikes me as being more violent than previous Bond films, showing him cleaning up after the action - indeed, some of his injuries

Quantum Cumputers By the strange laws of quantum mechanics, Folger, a senior editor at Discover, notes, an electron, proton, or other subatomic particle is "in more than one place at a time," because individual particles behave like waves, these different places are different states that an atom can exist in simultaneously. Ten years ago, Folger writes, David Deutsch, a physicist at Oxford University, argued that it may be possible to build an extremely powerful computer based on this peculiar

Reconciling Religious and Scientific Perspectives of Creation “In the beginning was the big bang,”[i] writes John Polkinghorne, a physicist turned theologian. As the reader follows through the remainder of his cosmic creation story, the reader is intrigued at how mystical and religious the story sounds. “The space boiled, in the rapid expansion of the inflation era, blowing the universe apart with incredible rapidity in the much less than 10-30 seconds that it lasted. . . . The world

Marquel Gray Prof. Heather Clark 7/22/13 Eng.111-60A The origin of life: Intelligent Design vs. materialistic naturalism The origin of life has been questioned by men for thousands of years. Scientist have studied the universe extensively and developed various theories to answer questions related to the origin of life. Questions like, how did life begin? Is the universe the result of chaotic chance or intelligent design? How did life on earth come to be? These are some of the many questions

An Atom is the the basic building block of all matter. Atoms are made up of Particles, called: Protons, neutrons and Electrons. Protons carry a positive charge, the neutron carry 's a neutral charge and the electron carry’s a negative charge. The Atom has two main parts the Nucleus and the Electron Shell. The Nucleus contains the Protons and Neutrons. The electron Shell Contains the The electrons. There are many Scientist that contributed in the investigation of the atom which are: 1- John Dalton

In school you learned about the atom as though the electrons were particles. But what if you were taught wrong? What if matter is in reality a wave? This is the question raised by Lois de Broglie and is the focus of this essay. First we will cover the difference between particles and waves. Then we will cover the origin of this debate, the duality of light and the double slit experiment. Then we will look at the man behind this unorthodox idea, what his scientific background is and his reasons for

1. A) Part of the wave might penetrate it or it might not. This would be random and would depend on the energy of the electron attempting to penetrate. B) The pattern that initially seemed random would begin to acquire uniformity. Half of the electrons would transmit and half would reflect and go back. Each of the electrons that transmitted would carry its complete charge and mass. C) One cannot say where the electron really is, whether a given electron will transmit or reflect. It is only possible
