SUMMARY:Lecture / Discussion:Professors Jie (Jackie) Li\, Ralf J. Spatzier\, and Nicholas A. Valentino\, Collegiate Professorship Inaugural Lecture
DESCRIPTION:This event will take place both in person and virtually.\n\nProfessor Jie (Jackie) Li\nRodney C. Ewing Collegiate Professor of Earth and Planetary Sciences\n\nLecture Title: From Diamonds to Dynamo: How Earth Stays Magnetic? \n\nLecture Abstract: Beneath the dancing lights of the aurora lies a 4-billion-year survival story. By recreating the extreme pressures and temperatures of Earth’s core with gem-quality diamonds and tightly focused lasers\, we peer into our planet’s deepest engine. There\, we uncover how a cooling Earth overcame major energy crises by switching its fuel source\, thereby sustaining the magnetic shield that protects life.\n\nProfessor Ralf J. Spatzier\nGopal Prasad Collegiate Professor of Mathematics\n\nLecture Title: Symmetry In Geometry and Dynamics:\nThe Role of Intuition in Mathematics Research\n\nLecture Abstract: How does mathematics progress? And how do\nmathematicians actually make progress?\n\nWe are actually making lots of progress\, and I hope I can\nconvince you! But there are many ways we achieve this. Let\nme tell you about it in my own case.\nLeading Question: How do I make progress?\n1: By working hard long hours in my office with my computer?\n2: By doing difficult calculations with pen and paper?\n3: By going for a walk?\nI will try to illuminate how fundamental progress happened in my\nown limited experience. It involved grand ideas such as\n“symmetry” and how it limits possibilities. A classical example\nare the Platonic solids\, i.e. convex regular polyhedra with\ncongruent faces (symmetry). Turns out there are only five.\nWhen a few mild harmless assumptions greatly limit the possible\nobjects and even completely determine a system\, we speak of\n“RIGIDITY”\, just as in the case of the platonic solids.\nIn my own research\, symmetry is an overriding principle\, leading\nto rigidity in geometry. As it happened - and after many walks -\nthis also inspired ideas for rigidity in dynamical systems with\nsymmetry.\nSymmetry and extremal properties have played a major role in\nmathematics for a long time. While I will start to discuss this in\n\nthe context of some Riemannian geometry\, I will emphasize more\nrecent work on dynamical systems. Here symmetry expresses\nitself in terms of having non-trivially commuting maps or flows\,\nor an action of some group with complicated relations. Case in\npoint are actions of semisimple Lie groups\, especially ones of\nhigher rank\, e.g. SL(n\,R) with n at least 3. This is the so-called\nZimmer program. I will hint at some recent highlights.\n\nProfessor Nicholas A. Valentino\nDonald R. Kinder Collegiate Professor of Political Science\n\nLecture Title: The Big River: Explorations on the Role of Race in Politics\n\nLecture Abstract: My work owes most of its inspiration to the Symbolic Politics Theory proposed originally by David Sears at UCLA in the 1980s and further developed by Donald Kinder here at Michigan. The central claim of that theory is that symbolic predispositions- partisanship\, racial identity\, prejudice- and the deeply rooted emotions associated with these attachments drive many political choices and behavior much more powerfully than material self-interest. The theory originally focused on explaining policy opinions and behaviors with direct and explicit consequences for the distribution of rights and resources between racial groups in America\, and even more narrowly on the black-white divides over affirmative action and the election of African American candidates. One of my main goals has been to broaden this exploration to political domains explicitly unrelated to race\, such as crime\, immigration\, government surveillance\, electoral laws\, and so on. In general\, my collaborators and I find that deeply rooted racial attitudes\, identities\, and emotional processes profoundly impact nearly every domain of politics. \n\nIf you are unable to join us in person\, please click the link below to join the webinar.\nJoin from PC\, Mac\, iPad\, or Android:\nhttps://umich.zoom.us/j/95783933422\n\nPhone one-tap:\n+13092053325\,\,95783933422# US\n+13126266799\,\,95783933422# US (Chicago)\n\nJoin via audio:\n+1 309 205 3325 US\n+1 312 626 6799 US (Chicago)\n+1 646 876 9923 US (New York)\n+1 646 931 3860 US\n+1 301 715 8592 US (Washington DC)\n+1 305 224 1968 US\n+1 719 359 4580 US\n+1 253 205 0468 US\n+1 253 215 8782 US (Tacoma)\n+1 346 248 7799 US (Houston)\n+1 360 209 5623 US\n+1 386 347 5053 US\n+1 507 473 4847 US\n+1 564 217 2000 US\n+1 669 444 9171 US\n+1 669 900 6833 US (San Jose)\n+1 689 278 1000 US\n+1 778 907 2071 Canada\n+1 780 666 0144 Canada\n+1 204 272 7920 Canada\n+1 438 809 7799 Canada\n+1 587 328 1099 Canada\n+1 647 374 4685 Canada\n+1 647 558 0588 Canada\nWebinar ID: 957 8393 3422\nInternational numbers available: https://umich.zoom.us/u/azI9zGShx
