On this episode, Nick speaks with Susanna Weygandt a scholar studying performance theories of Russian and East European theater. She discusses the work of Anatoly Vasiliev, famed Russian theater director for the Moscow School of Dramatic Arts. Thanks for listening! ABOUT THE GUEST: Elena Susanna Weygandt analyzes and documents performance theories indigenous to Russia and East Europe that have not yet been documented. She draws on methods of interview and ethnography as well as digital display in her research on contemporary topics. In her soon-to-be published book with the University of Wisconsin Press, From Metaphor to Direct Speech: Drama and Performance Theory in Contemporary Russia, she identifies the main writers and performance theories of the vibrant movement, Novaia Drama, and situates this pioneering literature in the contemporary Russian literary canon, the Performance Studies field, and within Post-Soviet studies. The New Dramatists assert that it is precisely in the theatre, with its inherent form of critique and reflection provided by the stage, where the contemporary moment of the present can be held at arm's length away, which creates enough of a distance from the present for a historical perspective about it to emerge. This research has shaped her into a scholar and teacher of visual language, the body, feminist art, gender, exhibition on digital platforms, and all genres of documentary and realism in Russian and East European literature. Her publications on these topics of cultural history in Russia and East Europe from 1953 to the present appear in The Russian Review, Studies in Russian and Soviet Cinema, TDR: The Drama Review, Apparatus: Film, Media, and Digital Cultures in Central and Eastern Europe, and in a co-edited anthology published by Columbia UP. She received her training in Slavic Languages and Literatures from Princeton (PhD 2015; Graduate Certificate in History of Science 2015). At Sewanee: The University of the South she teaches all levels of Russian in the Russian Department and her joint affiliation in the Humanities Program. https://new.sewanee.edu/programs-of-study/russian/faculty-staff/susanna-weygandt/ If you have questions, comments, or would like to be a guest on the show, please email slavxradio@utexas.edu and we will be in touch!

What can the ancient philosopher Plato teach us about building a network and thriving in today's intellectual economy? I talk with Alex Petkas, a Princeton PhD in classics, who shares insights on Plato's rise and his brand-building strategies within the decentralized world of Athens in the late fifth and fourth centuries BC, where widespread literacy and the new media technology of writing created an intellectual landscape strikingly similar to the one we inhabit today.(0:00:00) - Introduction(0:04:51) - Plato and Ancient Greek Writing(0:20:04) - Plato's Models and Brand Building(0:33:55) - Plato's Rise and Influence(0:43:45) - Plato and the Power of Mystery(0:52:44) - Plato's Network and Philosophical Training(1:02:44) - The Economic Machinery of Philosophy(1:07:56) - Plato's Power Machinery and Business Model(1:20:29) - Plato's Lessons on Building a Network(1:25:59) - Plato's Lessons for Decentralized Thinking(1:35:31) - Alex's Rome RetreatAlex Petkas | https://ancientlifecoach.com/Learn more about Alex's upcoming Men's Retreat in Rome: https://ancientlifecoach.com/retreat/Other Life✦ Subscribe to the coolest free newsletter in the world and I'll send you all of my private book highlights. https://otherlife.co✦ Join the Other Life community (free) https://otherlife.co/joinIndieThinkers.org✦ If you're working on independent projects, join the next cohort of https://IndieThinkers.org
It's easy to see Brad as a superhero because he's achieved things about which most of of us just dream: Naval Academy graduate, explosives expert, breaker of a thirty year old world record, gold medalist in his second Paralympic sport, husband, father and Ivy League PhD candidate, but his success is the product of his struggles. He was about to quit the swim team at Navy to concentrate on his studies before his teammates voted him Captain for his senior season. He had to talk his way into Explosives Ordnance School because his grades weren't competitive. Brad is a leader of men and women, who does his best to follow the example of his heroes and mentors, and with compassion and empathy. Strife and struggle have shaped who he is and he continues to seek their benefit daily.
Professor Ilian Mihov, Dean, INSEAD was once a student who caught sight of an advertisement for a scholarship for Bulgarian students to study in the US. He shares how he made it to a Princeton Phd on scholarship in this inspiring interview where he also shares his thoughts on who scholarships are for. Prof Mihov then slays a myth of how much an INSEAD education costs in this conversation with Michelle Martin. See omnystudio.com/listener for privacy information.
Today we will be talking about a new report that discusses one of the most critical topics for global emissions reduction: How China's most carbon-intensive industries are planning to decarbonize. Since September 2020 when President Xi Jinping announced that China would aim to peak emissions before 2030 and reach carbon neutrality by 2060, some of China's biggest companies have committed to new climate targets to meet that national goal. In this report, Columbia Center for Global Energy Policy Non-Resident Fellow and Princeton PhD student Ned Downie looks at the three of the highest emitting industries in China: electricity, steel, and cement and helps us understand exactly what those announcements add up to. Further reading: Edmund Downie, "Getting to 30-60: How China's Biggest Coal Power, Cement, and Steel Corporations Are Responding to National Decarbonization Pledges," Columbia Center on Global Energy Policy, 25 August 2021, at https://www.energypolicy.columbia.edu/research/report/getting-30-60-how-china-s-biggest-coal-power-cement-and-steel-corporations-are-responding-national. “Major News | A Carbon Emissions Declaration from the World's Biggest Steel Firm, China Baowu: Aiming for ‘Carbon Peaking' in 2023 and for Achieving ‘Carbon Neutrality' in 2050,” January 20, 2021, at http://mp.weixin.qq.com/s?__biz=MjM5MDEzNzA5Ng==&mid=2654852246&idx=1&sn=d479656526315c56691b0101482a16af&chksm=bd801af18af793e733b0f5cdd0d7d101eef0150feb831bddf9d705673f715b6128e57e0619d0#rd. “HBIS Announces Low-Carbon Green Development Action Plan,” HBIS WeChat channel, March 12, 2021, at http://mp.weixin.qq.com/s?__biz=MzA5MjA2Mjk3MA==&mid=2653109712&idx=1&sn=9539988bd1af53094e892177fc7752db&chksm=8ba54845bcd2c1533f04fc3a53789adb1e68c0dc5c3674a4007aea087b970cbaa2de89d27e83#rd.
In this episode of the 18Forty Podcast, we sit down with Dr. Rivka Press Schwartz – Shalom Hartman Institute Fellow, SAR Associate Principal, and Princeton PhD – to think about ways in which social justice can be incorporated into Orthodox education systems. History has seen many hierarchical class systems that benefit some to the detriment of others. The Jewish people have not often been the beneficiaries, yet we enjoy much economic and social success in much of the world today. Dr. Press Schwartz thinks that while this success is in part due to our own willpower, certain fluke historical factors have played in our favor, giving us a leg up. She believes that the Torah is compatible with a social view that involves recognizing social privileges and attempting to mitigate them. What is privilege? How privileged have the Jewish people been throughout history? What, if anything, should be done when privileges are identified? What does the Torah have to say about this? Tune in to hear Dr. Rivka Press Schwartz share her views on the Torah, the Jewish people, privilege, and broader social justice. For more, visit https://18forty.org/socialjustice/#pressschwartz.

In Episode 015 of A Medicinal Mind: Wisdom and Wellbeing, we explore the interface between science and spirituality, evolution and creationism, faith and the experimental method. I have a wonderful conversation with a dear friend and honorary family member, former governor of North Carolina and nurturing grandfather Jim Martin. Jim is a Princeton PhD organic chemist who initially taught at his alma mater Davidson College During that time, he played principal tuba in the Charlotte Symphony and officiated high school football. Drawn to politics as a precinct worker, he was then elected three times as county commissioner, six times to the U.S. Congress, and twice as Governor of North Carolina. After twenty-six years of public service, he returned to his scientific roots in private life to serve as vice president of medical research at Carolinas Medical Center in Charlotte. He and his wife Dottie have three children and five grandchildren in addition to being amazing family friends to my grandparents and all the Abbott's in my loving family. In our conversation Jim shares some amazing insights regarding the complexities of biology, organic chemistry, and physics as they relate to the current existence of humanity and our universe as a whole. In distilling down some of the major ideas in his groundbreaking book: Revelation Through Science Jim provides us with a small glimpse into some foundational scientific principles that perhaps, do not and WILL NEVER PROVE the existence of a God, but do indeed provide evidence POINTING TO the existence of a larger Creator. Introducing the concepts of irreducible complexities, the remarkable relational geometry of DNA, RNA, sugars, and amino acids, we explore that miraculous machinery that allows for the storage and interpretation of genetic code and the eventual creation of an incredible array of proteins and biologic tissues. Getting a little geeky, we, as two chemists explore the concepts of chirality or handedness of molecules. Why should we care if something is left handed or right handed? What does it mean to be left handed in the first place? And what the heck is a enantiomer? Changing gears, James and I explore Scripture and the biblical text Can we treat the Bible as a scientific textbook or as a book of relational and interpretive wisdom? Is it fair to judge the biblical text against our current understanding of the scientific method? Dancing into the beautiful trinity of sugars, RNA/DNA, and amino acids, Jim creates the wonderful three way chicken, egg and creator conundrum, what came first nucleic acids, or ribose and deoxyribose, or amino acids or perhaps something we don't even currently understand? I am so grateful to Jim for sharing this space with me and engaging in a thoughtful discussion seeking to bring peace to the supposed dichotomy between science and spirituality, providing a middle ground for individuals to recognize that you can both believe in God and evolution, use the scientific method and rely on faith for understanding. And please check out Jim's book: Revelation Through Science, it really is a fascinating collection of thoughtful scientific inquiry accessible to both the rigorous scientist and curious layperson. You can find links to Jim's page and his book in our show notes, as well as slides describing some of the concepts we discuss in the podcast, for those, like myself, who are rather visually inclined. I really hope you enjoy the show!

This is the last of four conversation Gudrun had during the British Applied Mathematics Colloquium which took place 5th – 8th April 2016 in Oxford. Andrea Bertozzi from the University of California in Los Angeles (UCLA) held a public lecture on The Mathematics of Crime. She has been Professor of Mathematics at UCLA since 2003 and Betsy Wood Knapp Chair for Innovation and Creativity (since 2012). From 1995-2004 she worked mostly at Duke University first as Associate Professor of Mathematics and then as Professor of Mathematics and Physics. As an undergraduate at Princeton University she studied physics and astronomy alongside her major in mathematics and went through a Princeton PhD-program. For her thesis she worked in applied analysis and studied fluid flow. As postdoc she worked with Peter Constantin at the University of Chicago (1991-1995) on global regularity for vortex patches. But even more importantly, this was the moment when she found research problems that needed knowledge about PDEs and flow but in addition both numerical analysis and scientific computing. She found out that she really likes to collaborate with very different specialists. Today hardwork can largely be carried out on a desktop but occasionally clusters or supercomputers are necessary. The initial request to work on Mathematics in crime came from a colleague, the social scientist Jeffrey Brantingham. He works in Anthropology at UCLA and had well established contacts with the police in LA. He was looking for mathematical input on some of his problems and raised that issue with Andrea Bertozzi. Her postdoc George Mohler came up with the idea to adapt an earthquake model after a discussion with Frederic Paik Schoenberg, a world expert in that field working at UCLA. The idea is to model crimes of opportunity as being triggered by crimes that already happend. So the likelihood of new crimes can be predicted as an excitation in space and time like the shock of an earthquake. Of course, here statistical models are necessary which say how the excitement is distributed and decays in space and time. Mathematically this is a self-exciting point process. The traditional Poisson process model has a single parameter and thus, no memory - i.e. no connections to other events can be modelled. The Hawkes process builds on the Poisson process as background noise but adds new events which then are triggering events according to an excitation rate and the exponential decay of excitation over time. This is a memory effect based on actual events (not only on a likelihood) and a three parameter model. It is not too difficult to process field data, fit data to that model and make an extrapolation in time. Meanwhile the results of that idea work really well in the field. Results of field trials both in the UK and US have just been published and there is a commercial product available providing services to the police. In addition to coming up with useful ideas and having an interdisciplinary group of people committed to make them work it was necessery to find funding in order to support students to work on that topic. The first grant came from the National Science Foundation and from this time on the group included George Tita (UC Irvine) a criminology expert in LA-Gangs and Lincoln Chayes as another mathematician in the team. The practical implementation of this crime prevention method for the police is as follows: Before the policemen go out on a shift they ususally meet to divide their teams over the area they are serving. The teams take the crime prediction for that shift which is calculated by the computer model on the basis of whatever data is available up to shift. According to expected spots of crimes they especially assign teams to monitor those areas more closely. After introducing this method in the police work in Santa Cruz (California) police observed a significant reduction of 27% in crime. Of course this is a wonderful success story. Another success story involves the career development of the students and postdocs who now have permanent positions. Since this was the first group in the US to bring mathematics to police work this opened a lot of doors for young people involved. Another interesting topic in the context of Mathematics and crime are gang crime data. As for the the crime prediction model the attack of one gang on a rival gang usually triggers another event soon afterwards. A well chosen group of undergraduates already is mathematically educated enough to study the temporary distribution of gang related crime in LA with 30 street gangs and a complex net of enemies. We are speaking about hundreds of crimes in one year related to the activity of gangs. The mathematical tool which proved to be useful was a maximum liklihood penalization model again for the Hawkes process applied on the expected retaliatory behaviour. A more complex problem, which was treated in a PhD-thesis, is to single out gangs which would be probably responsable for certain crimes. This means to solve the inverse problem: We know the time and the crime and want to find out who did it. The result was published in Inverse Problems 2011. The tool was a variational model with an energy which is related to the data. The missing information is guessed and then put into the energy . In finding the best guess related to the chosen energy model a probable candidate for the crime is found. For a small number of unsolved crimes one can just go through all possible combinations. For hundreds or even several hundreds of unsolved crimes - all combinations cannot be handled. We make it easier by increasing the number of choices and formulate a continuous instead of the discrete problem, for which the optimization works with a standard gradient descent algorithm. A third topic and a third tool is Compressed sensing. It looks at sparsitiy in data like the probability distribution for crime in different parts of the city. Usually the crime rate is high in certain areas of a city and very low in others. For these sharp changes one needs different methods since we have to allow for jumps. Here the total variation enters the model as the -norm of the gradient. It promotes sparsity of edges in the solution. Before coming up with this concept it was necessary to cross-validate quite a number of times, which is computational very expensive. So instead of in hours the result is obtained in a couple minutes now. When Andrea Bertozzi was a young child she spent a lot of Sundays in the Science museum in Boston and wanted to become a scientist when grown up. The only problem was, that she could not decide which science would be the best choice since she liked everything in the museum. Today she says having chosen applied mathematics indeed she can do all science since mathematics works as a connector between sciences and opens a lot of doors.

A more complex problem, which was treated in a PhD-thesis, is to single out gangs which would be probably responsable for certain crimes. This means to solve the inverse problem: We know the time and the crime and want to find out who did it. The result was published in Inverse Problems 2011. The tool was a variational model with an energy which is related to the data. The missing information is guessed and then put into the energy . In finding the best guess related to the chosen energy model a probable candidate for the crime is found. For a small number of unsolved crimes one can just go through all possible combinations. For hundreds or even several hundreds of unsolved crimes - all combinations cannot be handled. We make it easier by increasing the number of choices and formulate a continuous instead of the discrete problem, for which the optimization works with a standard gradient descent algorithm. A third topic and a third tool is Compressed sensing. It looks at sparsitiy in data like the probability distribution for crime in different parts of the city. Usually the crime rate is high in certain areas of a city and very low in others. For these sharp changes one needs different methods since we have to allow for jumps. Here the total variation enters the model as the -norm of the gradient. It promotes sparsity of edges in the solution. Before coming up with this concept it was necessary to cross-validate quite a number of times, which is computational very expensive. So instead of in hours the result is obtained in a couple minutes now. When Andrea Bertozzi was a young child she spent a lot of Sundays in the Science museum in Boston and wanted to become a scientist when grown up. The only problem was, that she could not decide which science would be the best choice since she liked everything in the museum. Today she says having chosen applied mathematics indeed she can do all science since mathematics works as a connector between sciences and opens a lot of doors.
