Annual Report to Industry Canada Covering the Objectives, Activities and Finances for the period August 1, 2008 to July 31, 2009 and Statement of Objectives for Next Year and the Future Perimeter Institute for Theoretical Physics 31 Caroline Street North Waterloo, Ontario N2L 2Y5 Table of Contents Pages Period A. August 1, 2008 to July 31, 2009 Objectives, Activities and Finances 2-52 Statement of Objectives, Introduction Objectives 1-12 with Related Activities and Achievements Financial Statements, Expenditures, Criteria and Investment Strategy Period B. August 1, 2009 and Beyond Statement of Objectives for Next Year and Future 53-54 1 Statement of Objectives Introduction In 2008-9, the Institute achieved many important objectives of its mandate, which is to advance pure research in specific areas of theoretical physics, and to provide high quality outreach programs that educate and inspire the Canadian public, particularly young people, about the importance of basic research, discovery and innovation. Full details are provided in the body of the report below, but it is worth highlighting several major milestones. These include: In October 2008, Prof. Neil Turok officially became Director of Perimeter Institute. Dr. Turok brings outstanding credentials both as a scientist and as a visionary leader, with the ability and ambition to position PI among the best theoretical physics research institutes in the world. Throughout the last year, Perimeter Institute‘s growing reputation and targeted recruitment activities led to an increased number of scientific visitors, and rapid growth of its research community.

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. -

"Of course I am happy to have won the prize, that Englert said he and his colleagues all understood goes without saying, but there is regret too that my the importance of their work but the idea that they colleague and friend, Robert Brout, is not there to one day would win the Nobel prize had never been share it," Englert told a press conference at the an issue.

2016 Faculty Research Lecture Flyer
THE 61ST ANNUAL FACULTY RESEARCH LECTURE Joseph Incandela Searching for the Genetic Code of our Universe Monday, October 17, 2016 / FREE 4:00 PM Reception/ 5:00 PM Lecture Corwin Pavilion University Center The 2012 discovery of the Higgs boson at the CERN LHC accelerator complex completes a powerful and comprehensive description of nature known as the standard model of particle physics. The next step is to find the new physics that underpins this model, which many physicists believe could solve mysteries first seen in astrophysical and cosmological data, such as dark matter and neutrino mixing. Professor Incandela will give a general overview of where things stand and what's being planned, including his own research plans to address these very fundamental questions about the universe. Joseph Incandela received his PhD from the University of Chicago under Professor Henry Frisch in 1986 for a search for magnetic monopoles using superconducting coils whose currents were measured by Superconducting Quantum Interference Devices. Awarded a CERN Fellowship in 1987, he joined the UA2 experiment at CERN and was a leading contributor to the first precision measurement of the mass of the Z boson. He then proposed and led the first search at a hadron collider for a Higgs boson using hadronic tau decay final states. He joined the CDF experiment as a Wilson Fellow at Fermilab in 1991 where he led silicon detector projects and also led the search for top quarks that provided the most significant contribution to the discovery of the top quark in 1995. With regard to the LHC, he created the US CMS Silicon tracker project in 1997 that eventually constructed and tested ~60% (by area) of the silicon strip tracking system. -

Nature Physics Advance Online Publication, 8 October 2013 Doi:10.1038/Nphys2800 Research Highlight Nobel Prize 2013: Englert
Nature Physics advance online publication, 8 October 2013 doi:10.1038/nphys2800 Research Highlight Nobel Prize 2013: Englert and Higgs Alison Wright The Nobel Prize in Physics 2013 has been awarded to François Englert and Peter Higgs "for the theoretical discovery of a mechanism that contributes to our understanding of the origin of mass of subatomic particles, and which recently was confirmed through the discovery of the predicted fundamental particle, by the ATLAS and CMS experiments at CERN's Large Hadron Collider". It is probably the most widely anticipated Nobel award ever made — even as the announcement on 8 October was delayed by an hour, it still seemed certain that the prize would be given for what is generally known as the Higgs mechanism, cemented by the discovery of a Higgs boson at CERN last year. The only uncertainty lay in quite who would claim a slice of the prize. In 1964, François Englert and his colleague Robert Brout published a paper1 in Physical Review Letters in which they outlined a possible mechanism for the generation of particle masses. A few weeks later — in a world without e-mail or preprint servers — Peter Higgs published a similar, independent work2, and also mentioned the existence of a particle associated with the postulated field that would provoke the mass-generating mechanism. (These have since been known as the Higgs boson, the Higgs field and the Higgs mechanism.) And just a few weeks later still, Gerald Guralnik, Carl Hagen and Tom Kibble followed up with their own, independent, version3 of the same mechanism. -
