Just like his predecessors, Trump continued to use instead the Armenian phrase “Meds Yeghern” (Great Crime) in a statement on the 105th anniversary of the genocide. “Today, we join the global community in memorializing the lives lost during the Meds Yeghern, one of the worst mass atrocities of the 20th century,” read the statement. “Beginning in 1915, 1 and a half million Armenians were deported, massacred, ARMENIA MARKS GENOCIDE ANNIVERSARY YEREVAN (RFE/RL) — Armenia’s leaders laid flowers at the Tsitsernakabert memo- or marched to their rial in Yerevan on April 24 during official commemorations of the 105th anniversary of the Armenian genocide in Ottoman Turkey which were deaths in the final scaled back due to the coronavirus pandemic.

Reflections on the Renormalization Procedure for Gauge Theories
Reflections on the renormalization procedure for gauge theories Gerard ’t Hooft Institute for Theoretical Physics EMMEΦ Centre for Extreme Matter and Emergent Phenomena Science Faculty Utrecht University POBox 80.195 3808TD, Utrecht The Netherlands Internet: http://www.staff.science.uu.nl/˜hooft101/ In memory of Raymond Stora 1930 – 2015 Abstract Various pieces of insight were needed to formulate the rules for working with gauge theories of the electro-magnetic, weak and strong forces. First, it was needed to understand how to formulate the Feynman rules. We had to learn that there are many different ways to derive them, and it was needed to know arXiv:1604.06257v1 [hep-th] 21 Apr 2016 how different formulations of the gauge constraint lead to the same final re- sults: the calculated values of the scattering amplitudes. The rules for dealing with the infinities that had to be subtracted were a big challenge, culminating in the discovery of the Becchi-Rouet-Stora-Tyutin symmetry. Fond recollec- tions of the numerous discussions the author had with Raymond Stora on this topic are memorised here. We end with some reflections on the mathematical status of quantum field theories, and a letter sent by Stora to the author. Version: March 2016 Last typeset: April 22, 2016 1 1 Introduction Around the year 1970, rapid changes took place in our views of elementary particle physics, and in particular the role of local gauge theories and spontaneous symmetry breaking in these theories. For a long time, only few researchers had been convinced that quantum field theory was the way to go. -

30388 OID RS Annual Review
Review of the Year 2005/06 >> President’s foreword In the period covered by this review*, the Royal Society has continued and extended its activities over a wide front. There has, in particular, been an expansion in our international contacts and our engagement with global scientific issues. The joint statements on climate change and science in Africa, published in June 2005 by the science academies of the G8 nations, made a significant impact on the discussion before and at the Gleneagles summit. Following the success of these unprecedented statements, both of which were initiated by the Society, representatives of the science academies met at our premises in September 2005 to discuss how they might provide further independent advice to the governments of the G8. A key outcome of the meeting was an We have devoted increasing effort to nurturing agreement to prepare joint statements on the development of science academies overseas, energy security and infectious diseases ahead particularly in sub-Saharan Africa, and are of the St Petersburg summit in July 2006. building initiatives with academies in African The production of these statements, led by the countries through the Network of African Russian science academy, was a further Science Academies (NASAC). This is indicative illustration of the value of science academies of the long-term commitment we have made to working together to tackle issues of help African nations build their capacity in international importance. science, technology, engineering and medicine, particularly in universities and colleges. In 2004, the Society published, jointly with the Royal Academy of Engineering, a widely Much of the progress we have has made in acclaimed report on the potential health, recent years on the international stage has been environmental and social impacts of achieved through the tireless work of Professor nanotechnologies. -
