The 1st Liberal Arts Education Conference was organised by Prof Fujia Yang (University of Nottingham Ningbo China) in April 2014 and it was a resounding success. This second conference featured a distinguished panel of experts from China, South Korea, Hong Kong, Macau, Taiwan, India, Philippines and Singapore. Co- chaired by Prof Phua Kok Khoo (IAS) and Prof Alan Chan (CoHASS), the Opening Ceremony was graced by Prof Guaning Su, Emeritus President of NTU. Over the two-day conference, the distinguished speakers shared their insights and thoughts on the topic of critical importance to future human development. In his presentation on “Promoting Cultural Diversity, Prof Alan Chan (Dean, College of Humanities, Arts and Social Integrity and Global Leadership in KAIST Education”, Prof Sciences, NTU) speaking on the challenges and opportunities Steve Kang (President of Korea Advanced Institute of for the Arts and Humanities in NTU. Science and Technology) highlighted Korea’s higher education system, which placed heavy emphasis on technical education and specialisation. While it was the driving force for Korea’s rapid economic growth in the 20th century, Prof Kang said that the nation’s unhealthy fixation over college exams had led to a skewed emphasis in education. More than just providing students with technical know-how, universities today must groom graduates who are global citizens: creative, knowledgeable in current affairs and capable of effective communication across cultures. Going to another part of Asia, Prof Anita Patankar (Director, Symbiosis School for Liberal Arts) described her experiences of liberal arts education in India. In her talk titled “Looking Towards New Models of Liberal Arts Education for National Development”, Prof Patankar commented how the phenomenon of globalisation has changed almost every aspect of life as we know it, including higher education. She closely examined the Prof Fujia Yang (President, University of Nottingham Ningbo China) need for undergraduate colleges to explore the option discussed the Copenhagen Spirit and Liberal Arts Education. JANUARY 2016 | 3 IAS NEWSLETTER - ISSUE 18 FEATURES of incorporating liberal arts philosophy in the curriculum as part of the process of learning to adapt to the changes brought about by rapid globalisation. Closer to home, Prof Pericles Lewis (President of NUS- Yale College)’s talk on “Innovation in Liberal Education” discussed how Singapore’s first liberal arts college, NUS- Yale College, through innovative means, had incorporated both Asian and Western influences in humanistic, social, and scientific studies, to create a common curriculum for their students. In such an environment, students are encouraged to be risk takers, to experiment, and challenge themselves to go beyond their comfort zones. The presentations by all the speakers were illustrated vividly with examples of student activities and exciting recounts from each speaker’s personal experiences. The highlight of the conference was the roundtable Prof Chia-Wei Woo (Founding President, Hong Kong University of discussion on “Liberal Arts Education in the 21st Century”, Science and Technology) engaging in the conference discussion.

  • Having a Good Time: a Triumph of Science & Technology
    UDC’s Office of Research & Graduate Studies, SEAS, LSAMP, & STEM Center Invite You to a Seminar on Having a Good Time: A Triumph of Science & Technology Presented by Dr. William D. Phillips, NIST Nobel Laureate in Physics, 1997 © Robert Rathe © Robert Rathe Date: Tuesday, March 13, 2012 Time: 12:30 PM Location: Building 41-A03 Abstract: People have long been interested in timekeeping. In the 18th century, this interest became particularly keen because of technological demands: the need for accurate navigation on the high seas. While many people believed that the answer to sufficiently good timekeeping at sea would be found in astronomical measurements, it was earthbound engineering that literally won the prize. The construction of accurate seagoing clocks revolutionized navigation in the 18th and 19th centuries. The advent of even more accurate clocks—atomic clocks—in the 20th century gave birth to a new revolution in navigation—the Global Positioning System. This ever-more advanced system for satellite navigation owes its success both to excellent engineering and to seemingly arcane science. Dr. William D. Phillips is a Senior Fellow at the National Institute of Standards and Technology (NIST), where he leads the Laser Cooling and Trapping Group. He shared the 1997 Nobel Prize in physics with Dr. Steven Chu, now Secretary of Energy, and with Dr. Claude Cohen-Tannoudji, an Algerian-born French physicist, “for development of methods to cool and trap atoms with laser light.” With a physics bachelor’s degree from Juniata College in Pennsylvania and a Ph.D. from MIT, Phillips started his career at NIST only a few years after it left UDC’s Van Ness campus for its location in Gaithersburg.

Everything from elementary particles to celestial bodies, from electromagnetic wave to gravity is in eternal motions, which dissects only to circle. Since everything is described only by trigonometry. Without trigonometry and mathematical circle, the science cannot indicate all the beauty of harmonic universe. Other method may be very good, but it is not perfect. Some part is very nice, another part is problematic. General Theory of Relativity holds that gravity is geometric. Quantum Mechanics describes all particles by wave function of trigonometry. In this paper using trigonometry, particularly mathematics circle, a possible version of the unification of partial theories, evolution history and structure of expanding universe, and the parallel universes are shown. Keywords: HRD, Trigonometry, Projection of Circle, Singularity, The reality of universe describes by geometry, because of that not Celestial Body, Black Hole and Parallel Universes. only gravity is geometrical, but everything is it and nothing is linear. One of the important branches of geometry is trigonometry dealing Introduction with circle and triangle. For this reason, it is easier to describe nature Today scientists describe the universe in terms of two basic partial of universe by mathematics circle.

  • The Discovery of Asymptotic Freedom
    The Discovery of Asymptotic Freedom The 2004 Nobel Prize in Physics, awarded to David Gross, Frank Wilczek, and David Politzer, recognizes the key discovery that explained how quarks, the elementary constituents of the atomic nucleus, are bound together to form protons and neutrons. In 1973, Gross and Wilczek, working at Princeton, and Politzer, working independently at Harvard, showed that the attraction between quarks grows weaker as the quarks approach one another more closely, and correspondingly that the attraction grows stronger as the quarks are separated. This discovery, known as “asymptotic freedom,” established quantum chromodynamics (QCD) as the correct theory of the strong nuclear force, one of the four fundamental forces in Nature. At the time of the discovery, Wilczek was a 21-year-old graduate student working under Gross’s supervision at Princeton, while Politzer was a 23-year-old graduate student at Harvard. Currently Gross is the Director of the Kavli Institute for Theoretical Physics at the University of California at Santa Barbara, and Wilczek is the Herman Feshbach Professor of Physics at MIT. Politzer is Professor of Theoretical Physics at Caltech; he joined the Caltech faculty in 1976. Of the four fundamental forces --- the others besides the strong nuclear force are electromagnetism, the weak nuclear force (responsible for the decay of radioactive nuclei), and gravitation --- the strong force was by far the most poorly understood in the early 1970s. It had been suggested in 1964 by Caltech physicist Murray Gell-Mann that protons and neutrons contain more elementary objects, which he called quarks. Yet isolated quarks are never seen, indicating that the quarks are permanently bound together by powerful nuclear forces.

Box 50005, SE-104 05 Stockholm, Sweden Phone: +46 8 673 95 00, Fax: +46 8 15 56 70, E-mail: [email protected], Website: www.kva.se Asymptotic Freedom and Quantum ChromoDynamics: the Key to the Understanding of the Strong Nuclear Forces The Basic Forces in Nature We know of two fundamental forces on the macroscopic scale that we experience in daily life: the gravitational force that binds our solar system together and keeps us on earth, and the electromagnetic force between electrically charged objects. Both are mediated over a distance and the force is proportional to the inverse square of the distance between the objects. Isaac Newton described the gravitational force in his Principia in 1687, and in 1915 Albert Einstein (Nobel Prize, 1921 for the photoelectric effect) presented his General Theory of Relativity for the gravitational force, which generalized Newton’s theory. Einstein’s theory is perhaps the greatest achievement in the history of science and the most celebrated one. The laws for the electromagnetic force were formulated by James Clark Maxwell in 1873, also a great leap forward in human endeavour. With the advent of quantum mechanics in the first decades of the 20th century it was realized that the electromagnetic field, including light, is quantized and can be seen as a stream of particles, photons. In this picture, the electromagnetic force can be thought of as a bombardment of photons, as when one object is thrown to another to transmit a force.

  • Weyl Spinors and the Helicity Formalism
    Weyl spinors and the helicity formalism J. L. D´ıazCruz, Bryan Larios, Oscar Meza Aldama, Jonathan Reyes P´erez Facultad de Ciencias F´ısico-Matem´aticas, Benem´erita Universidad Aut´onomade Puebla, Av. San Claudio y 18 Sur, C. U. 72570 Puebla, M´exico Abstract. In this work we give a review of the original formulation of the relativistic wave equation for parti- cles with spin one-half. Traditionally (`ala Dirac), it's proposed that the \square root" of the Klein-Gordon (K-G) equation involves a 4 component (Dirac) spinor and in the non-relativistic limit it can be written as 2 equations for two 2 component spinors. On the other hand, there exists Weyl's formalism, in which one works from the beginning with 2 component Weyl spinors, which are the fundamental objects of the helicity formalism. In this work we rederive Weyl's equations directly, starting from K-G equation. We also obtain the electromagnetic interaction through minimal coupling and we get the interaction with the magnetic moment. As an example of the use of that formalism, we calculate Compton scattering using the helicity methods. Keywords: Weyl spinors, helicity formalism, Compton scattering. PACS: 03.65.Pm; 11.80.Cr 1 Introduction One of the cornerstones of contemporary physics is quantum mechanics, thanks to which great advances in the comprehension of nature at the atomic, and even subatomic level have been achieved. On the other hand, its applications have given place to a whole new technological revolution. Thus, the study of quantum physics is part of our scientific culture.
