Appendix E Nobel Prizes in Nuclear Science
Nuclear Science—A Guide to the Nuclear Science Wall Chart ©2018 Contemporary Physics Education Project (CPEP) Appendix E Nobel Prizes in Nuclear Science Many Nobel Prizes have been awarded for nuclear research and instrumentation. The field has spun off: particle physics, nuclear astrophysics, nuclear power reactors, nuclear medicine, and nuclear weapons. Understanding how the nucleus works and applying that knowledge to technology has been one of the most significant accomplishments of twentieth century scientific research. Each prize was awarded for physics unless otherwise noted.

Brief Study of Various Tourism of Rajasthan: a Review
Pramana Research Journal ISSN NO: 2249-2976 BRIEF STUDY OF VARIOUS TOURISM OF RAJASTHAN: A REVIEW Prankur Arya M.A. Student, Maharaja Ganga Singh University, Bikaner Abstract: This paper aims to provide a brief review of tourism that is found in Rajasthan. Rajasthan is considered as main tourism state in nation. The legacy of Rajasthan with bright living customs, traditions, wonderful heritage, fascinating natural beauty, folk performances, energetic people and delicious cuisines are exceptional attractions for both domestic and foreign tourists. Tourism can be of many types like science tourism, sustainable tourism, and city tourism and so on. In our work we have discussed about dark and educational tourism of Rajasthan. Keywords: Dark tourism, Educational Tourism, sustainable tourism. Introduction: In today’s time every moment many people are making plans to travel across the world for personal and professional purposes. Earlier people used to travel for religious, ethical, safety etc. but as time changes the mind set of people is changing. Now people are travelling to explore, rest and pleasure. The travel plans can be shorter or longer holidays and they are organized by tourism industry [1]. The travel industry is one of the greatest developing enterprises on earth and its authority seems secure if the present rate of development is kept up by World Tourism Organization (WTO, 2010). This likewise incorporates the People, who are in charge of giving administrations, security, direction, confirmation, and association to the voyagers, by working at the front or at the back. At the point when Tourists go starting with one spot then onto the next and come to home, they give commitment in this industry. -
Nobel Prize Physicists Meet at Lindau

Its Selflessness,Friendliness, Statesmanship, Helped to Establish
Leonard I. Schiff died on January 19, 1971 in the midst of a full life, which was unusual for its selflessness, friendliness, statesmanship, and remarkable scientific productivity. He was a teacherand scholar of extraordinary breadth. In his memory and to affirm the high standards in lecturing and research that he so greatly helped to establish, it is most fitting to bring to Stanford a diverse group of outstanding physicists. The Physics Department is establishing a memorial fund, which will be used to support an annual Distinguished Lectureship for physicists of great distinction who will be invited to give a memorial lecture open to the public. Ii is hoped that sufficient funds will be raised to enable the Distinguished Lecturer on occasion to remain in the Department for an extensive stay so that he can interact with students and faculty. Contributions and pledges to the Leonard I. Schiff Memorial Fund should be mailed to the Departmentof Physics, Stanford University, California 94305.

Sidney D. Drell 1926–2016 A Biographical Memoir by Robert Jaffe and Raymond Jeanloz ©2018 National Academy of Sciences. Any opinions expressed in this memoir are those of the authors and do not necessarily reflect the views of the National Academy of Sciences. SIDNEY daVID DRELL September 13, 1926–December 21, 2016 Elected to the NAS, 1969 Sidney David Drell, professor emeritus at Stanford Univer- sity and senior fellow at the Hoover Institution, died shortly after his 90th birthday in Palo Alto, California. In a career spanning nearly 70 years, Sid—as he was universally known—achieved prominence as a theoretical physicist, public servant, and humanitarian. Sid contributed incisively to our understanding of the elec- tromagnetic properties of matter. He created the theory group at the Stanford Linear Accelerator Center (SLAC) and led it through the most creative period in elementary particle physics. The Drell-Yan mechanism is the process through which many particles of the Standard Model, including the famous Higgs boson, were discovered. By Robert Jaffe and Raymond Jeanloz Sid advised Presidents and Cabinet Members on matters ranging from nuclear weapons to intelligence, speaking truth to power but with keen insight for offering politically effective advice. His special friendships with Wolfgang (Pief) Panofsky, Andrei Sakharov, and George Shultz highlighted his work at the interface between science and human affairs. He advocated widely for the intellectual freedom of scientists and in his later years campaigned tirelessly to rid the world of nuclear weapons. Early life1 and work Sid Drell was born on September 13, 1926 in Atlantic City, New Jersey, on a small street between Oriental Avenue and Boardwalk—“among the places on the Monopoly board,” as he was fond of saying. -

Scientific Tourism Development Bases in Armenia
SocioEconomic Challenges, Volume 2, Issue 1, 2018 Scientific Tourism Development Bases in Armenia Gayane Tovmasyan PhD in Economics, Researcher at “AMBERD” Research Center of the Armenian State University of Eco- nomics, Professor at the Public Administration Academy of the Republic of Armenia, the Republic of Arme- nia Rubik Tovmasyan PhD in Economics, Docent at Armenian National Agrarian University, the Republic of Armenia Abstract Tourism is one of the most rapidly developing branches of the world economy. Scientific tourism is one of the types of tourism which is often considered as knowledge oriented or learning tourism. It is organized mainly by researchers, students, academics, scientists in order to conduct research in a specific area. Scien- tific tourism activities include participation in expeditions, excavations, congresses, conferences, experi- ments, contests and other scientific events. In this case science and tourism are connected to each other, as science development promotes tourism. Armenia has a rich scientific heritage. Many Armenian universities, museums, observatories, laboratories, reservations may be of high interest for touristic visits. Besides, Armenian scientific centers may implement international scientific programs including international known scientists and specialists. The aim of this article is to present the essence of scientific tourism, to analyze the bases of scientific tourism development in Armenia, to find out the existing problems and find some solutions for them. At the end of the conducted -

FELIX BLOCH October 23, 1905-September 10, 1983

Biographical Memoir COPYRIGHT 1994 NATIONAL ACADEMY OF SCIENCES WASHINGTON D.C. FELIX BLOCH October 23, 1905-September 10, 1983 BY ROBERT HOFSTADTER ELIX BLOCH was a historic figure in the development of Fphysics in the twentieth century. He was one among the great innovators who first showed that quantum me- chanics was a valid instrument for understanding many physi- cal phenomena for which there had been no previous ex- planation. Among many contributions were his pioneering efforts in the quantum theory of metals and solids, which resulted in what are called "Bloch Waves" or "Bloch States" and, later, "Bloch Walls," which separate magnetic domains in ferromagnetic materials. His name is associated with the famous Bethe-Bloch formula, which describes the stopping of charged particles in matter. The theory of "Spin Waves" was also developed by Bloch. His early work on the mag- netic scattering of neutrons led to his famous experiment with Alvarez that determined the magnetic moment of the neutron. In carrying out this resonance experiment, Bloch realized that magnetic moments of nuclei in general could be measured by resonance methods. This idea led to the discovery of nuclear magnetic resonance, which Bloch origi- nally called nuclear induction. For this and the simulta- neous and independent work of E.
