Public, Private, Secret is the premiere exhibition at the new ICP Museum, located at 250 Bowery. Organized by Curator-in-Residence, Charlotte Cotton, with ICP Associate Curator Pauline Vermare and Assistant Curator Marina Chao, the debut show and events program explore the concept of privacy in today’s society and studies how contemporary self-identity is tied to public visibility. This thought-provoking exhibition presents a wide range of historical and contemporary works by artists including Zach Blas, Martine Syms, Natalie Bookchin, Cindy Sherman, Nan Goldin, and Andy Warhol. Streams of real-time images and videos from various social media sources—curated with Mark Ghuneim and ICP’s New Media Narratives students—sharpen and heighten attention towards the social implications of our image-centric world. The Public, Private, Secret exhibition website is an integral part of the show experience, home to interviews with artists and curators and essays related to the exhibition’s themes, as well as images of works in the exhibition, a schedule of upcoming events, transcripts of past events, and press.

By approaching them in the context of their cultural, philosophical, political, social, economic, and ecologic entanglements, students will gain a much more critical perception of the potential implications they carry than they might otherwise encounter. Of course, technological infrastructures have long become ecological both in terms of material needs requiring a restructuring of old and establishment of new infrastructures (such as rare earth mineral mining, transport, recycling, waste, etc.), and through which the Anthropocene has long become the Technocene. The ubiquity and behavior of these infrastructures both in IoT objects, as well as distributed systems, has been modeled after the techno-ecologic thought of the Baroque and Cybernetics and are thus in critical need of analysis. From institutional critique to infrastructural critique, the course develops countertactics in theory and practice, while closing with a hands-on cryptology workshop (PGP, TOR, encrypted messaging, introduction to Tails Linux etc.).

EE380: Computer Systems Colloquium Seminar Unethical Algorithms of Massive Scale: New Data, a New Discovery, a New Tracking System, and a New Organization Speaker: Robert Epstein, The Sunlight Society and The American Institute for Behaviorial Research and Technology The Internet has made possible new means of manipulating opinions, purchases and votes that are unprecedented in human history in their effectiveness, scale and clandestine nature. Whether closely guided by human hands or operating independently of their creators, these algorithms now guide human decision making 24/7, often in ways that have ethical consequences. Biased search rankings, for example, have been shown to shift the voting preferences of undecided voters dramatically without any awareness on their part that they are being manipulated (the Search Engine Manipulation Effect, or SEME). Recent research shows that SEME can impact a wide range of opinions, not just voting preferences, and that multiple searches increase SEME's impact. New experiments also help to explain why SEME is so powerful and demonstrate how SEME can be suppressed to some extent. In 2016, new research also demonstrated that search suggestions (in "autocomplete") can also be used shift opinions and votes (the Search Suggestion Effect, or SSE). Demonstrating these possibilities in research is one thing; do search engine companies actually show people search suggestions or search results that are biased in some way? In 2016, AIBRT researchers recruited a nationwide network of field agents whose election-related searches were collected and aggregated for six months before the November election, thus preserving 13,207 searchers and the 98,044 web pages to which the search results linked. This unique data set revealed that that search results were indeed biased toward one candidate during most of this period in all 10 search positions on the first page of search results - enough, perhaps, to shift millions of votes without people's knowledge. Based on the success of this tracking effort, in early 2017, experts in multiple fields and at multiple universities in the US and Europe came together to creates The Sunlight Society (http://TheSunlightSociety.org), a nonprofit organization devoted to creating a worldwide ecosystem of passive monitoring software that will reveal a wide range of online manipulations as they are occurring, thus providing a means for identifying unethical algorithms as they are launched. About the Speaker: Robert Epstein is Senior Research Psychologist at the American Institute for Behavioral Research and Technology (AIBRT) in Vista, California, as well as the former editor-in-chief of Psychology Today magazine and the founder and director emeritus of the Cambridge Center for Behavioral Studies. A Ph.D. of Harvard University, he has published 15 books on artificial intelligence, creativity, stress management, and other topics, as well as more than 250 scientific and popular articles in publications such as Science, Nature, Psychological Science, TIME, Discover, U.S. News & World Report, and Scientific American Mind, where Dr. Epstein is a contributing editor.

Yet even after Andrew Wiles’s proof more than 300 years later, we’re still left wondering: what proof did Fermat have in mind? The mystery surrounding Fermat’s last theorem may have to do with the way we understand prime numbers. You all know what prime numbers are. An integer greater than 1 is called prime if it has exactly two factors: 1 and itself. In other words, p is prime if whenever you write p as a product of two integers, then one of those integers turns out to be 1. In fact, this definition works for negative integers, too. We simply incorporate -1. But the prime numbers satisfy another definition that maybe you haven’t thought about: An integer p is prime if, whenever p divides a product of two integers, then p divides at least one of those two integers.

Neuro-torture, algorithmic warfare, drones strikes, cybernetic nation-building are not means or ends but tests. Can a polis be engineered? Can the human operating system be reformatted? Can violence be modulated until legally invisible while all the more lethal? Each incursion, each new actor or actant, new terrains from brains to transatlantic cables, all find themselves part of a grand experiment. Over the course of this seminar we will explore how classically Realist concepts of order and national interest have been subtly displaced by subterranean violence entrepreneurs that populate the transversal battlefield of security politics. Doomsayers like Paul Virilio, Lewis Mumford, and Martin Heidegger who foretold a kind of terminal and self-annihilating velocity of security's technological saturation are today being shown to have been optimists. Security doesn’t know totality or finality: it bleeds, mutates, and reforms. Furthermore the peril of biopolitics seems now almost romantic. The care and concern for life’s productivity is increasingly subsumed by plasticity—forming and reforming without regard to the telos of productivity, division, or normative order. There are of course orders in our geoplastic age but they are almost unrecognizable as such when so many are directly invested in the intensifying failure of publically-stated strategic ends. In an attempt to confront the particular differences that mark our historical moment we will explore thinkers and practices that organize violence and pain beyond the limits of identity and mortality. We are witnessing creative and horrifying experiments in the affirmative production of dying that also deprive those targeted, in some cases whole population, from the relief of death. The horror of security politics is not tragic. Tragedy redeems. The horror of contemporary security politics is precisely that there is no relief, no reason, no victory, no defeats, no exit. Throughout this seminar, therefore, we will explore the problem of life and identity in the age of sustainable warfare.

Today, 185 years after Hegel’s death, several contemporary philosophers have enlisted Hegel in their attempts to comprehend our time in thought. What is striking however is that these philosophers invoke Hegel as the inspiration for radically antagonistic comprehensions of our present. Since the spontaneous comprehension of our present is as a time of catastrophic crisis it is unsurprising that the comprehension of crisis should be riven by a crisis of comprehension. The power of Hegel’s thought, and its contemporary salience, so this course will argue, is that crises of comprehension must yield comprehensions of crisis that obligate their critical overcoming. The necessity at issue is rational and it is precisely the status of rational necessity that is at stake in these antagonistic reactivations of Hegel. The claim that Hegelian rationalism is committed to converting crises of comprehension into their comprehensive overcoming will be tested against those who emphasize the conciliatory, integrative aspect of Hegel’s rationalism at the expense of traumatic discontinuities, but also against the attempt to convert Hegel’s thought into a tragic meditation on the impossibility of rationally overcoming trauma. We will trace the schism between these integrative and disintegrative reactivations of Hegel back to conceptual issues about the status of rationality, metaphysics, critique, dialectics, and the absolute in Hegel’s thought. We will also try to understand how these conceptual antagonisms give rise to fundamental political antagonisms, not only between social democratic reformism and revolutionary communism, but also between communism as a possible object of affirmation and communism as an impossible lost object of mourning.

Gregory Chaitin (b. 1947) is a mathematician, an expert in complexity. Already as a young prodigy he contributed greatly to the philosophy of mathematics and computer science. Chaitin states that although there are truths in science that cannot be proven, there is reason for huge optimism. This natural born rebel has been recently constructing a theory of the source of beauty and creativity in nature. The new theory that he calls metabiology. We’re meeting Gregory and Virginia – his wife, his muse, his intellectual partner and scientific collaborator – at the tiny Brazilian island of Paqueta, their philosophical retreat. Against Method is an episode of the Pioneers series, the unique documentary film project devoted to the most unorthodox contemporary thinkers who challenge current paradigms and go against the “publish or perish” decree.

http://thatchannel.com https://www.patreon.com/thatchannel http://www.helical-structures.org Stoyan Sarg has worked in both the Russian and Canadian space agencies, and has been a professor at York University and other universities. Warning against nuclear war, his view of physics cautions that multiple explosions could create a vortex that could drain the Earth's atmosphere and oceans into space, a fate that perhaps affected Mars in the distant past. Stoyan's theory of matter acknowledges "ether" and has a new model for the atom. The treatise BASIC STRUCTURES OF MATTER – SUPERGRAVITATION UNIFIED THEORY (BSM-SG) is based on an original idea about physical vacuum, which has never been investigated before. It follows the recommendation of James Clerk Maxwell expressed in his "A Treatise on Electricity and Magnetism" vol. II, section "A medium necessary": In fact, whenever energy is transmitted from one body to another in time, there must be a medium or substance in which the energy exist after it leaves one body and before it reaches the other... Hence, all these theories lead to the conception of a medium in which the propagation takes place The BSM-SG theory unveils the relation between the forces in Nature by adopting the following framework: - Empty Euclidian space without any physical properties and restrictions - Two super dens fundamental particles able to vibrate and congregate. Their parameters are associated with the Planck’s scale. - A Fundamental law of Super Gravitation (SG) - an inverse cubic law valid in pure empty space. An enormous abundance of these two particles, with energy beyond some critical level, are able to congregate into self-organized hierarchical levels of geometrical formations, based on the fundamental SG law. This leads deterministically to creation of space with quantum properties (known as physical vacuum) and a galaxy as observable matter. All known laws of Physics are embedded in the underlying structure of the physical vacuum and the structure of the elementary particles. The fundamental SG law is behind the gravitational, electric and magnetic fields and governs all kinds of interactions between the elementary particles in the space of physical vacuum. The revealed structures of the physical vacuum and elementary particles with interactions governed by SG law permit analysis of longstanding problems in different fields of Physics (Particle Physics, Quantum mechanics, Relativity and Cosmology) by using a classical approach in a real 3-D Euclidian space. The gravity and the electrical charge are not intrinsic features of the particles, but effects of interaction between particle's structure and the fine structure of the physical vacuum. The magnetism and inertia are specific reaction effects of the physical vacuum in a case of particle motion. The applied original approach permits a deeper insight into lower levels of matter organization, levels below the elementary particles. Any physical phenomenon or unsolved problem could be effectively analyzed at such levels. Every point of space in which we live and observe (down to ~ 1X10-20 m) contains two types of Zero Point Energy (ZPE) - a static and a dynamic one. Presently, the dynamic one is only envisioned by contemporary physics. The observable signature of the dynamic ZPE is the Microwave Cosmic Background temperature of 2.72K. (see the derived results in Chapter 5 of BSM). The hidden static ZPE is much larger and it is a source of the nuclear energy.

In today's volatile environment, leaders of global organizations must master a slate of challenges unseen in business history. In our new series, "Leading in the 21st century,", McKinsey spoke with seven leaders and Wharton professor Michael Useem, who offered an overview of the leadership challenges facing executives today. In this first segment, he sat down with McKinsey Publishing's Bill Javetski in August 2012 to talk about how traditional leadership qualities have changed in the modern era. Find the full transcript and other interviews in the series at McKinsey's web site: http://bit.ly/Leadership21st The director of the Center for Leadership and Change Management at the Wharton School, University of Pennsylvania, Professor Useem is the the author of, among other books, The Leader's Checklist. He has led leadership programs with dozens of multinational companies and developed a view of leadership that blends the need for fundamentals—vision, strategy, communication skills—with the evolving complexities of a globalizing world in which corporations strive to operate in scores of diverse countries.

"The Simons Institute for the Theory of Computing, together with the Mathematical Sciences Research Institute (MSRI) and Berkeley City College (BCC) presented a lecture by Dr. Michael Sipser - "Beyond Computation: The P versus NP Question". The event took place on May 9, 2014, at Berkeley City College What are the theoretical limitations of computer power? In a remarkable 1956 letter, the great logician Kurt Gödel first raised this question when he asked the famous mathematician and computer pioneer John von Neumann whether certain computational problems could be solved without resorting to a brute force search through many possibilities. In so doing, he foreshadowed the P versus NP question, one of the major unanswered questions of contemporary mathematics and theoretical computer science. This question asks whether every problem whose solution can be easily verified by a computer can also be easily solved by a computer. An answer to this question would reveal the potential for computers to solve puzzles, crack codes, prove theorems, and optimize many practical tasks.

Prominent clashes — both historical and contemporary — have led to the widely held conclusion that science and religion are fundamentally incompatible. Yet, many scientists practice a traditional faith, having found a way to accommodate both scientific inquiry and religious teaching in their belief system. Other scientists are bringing science to bear on the phenomenon of religion and spiritual belief — neuroscientists are studying what happens in the brain during religious experiences, while anthropologists are investigating how religion is linked to cooperation and community. This program provided an intimate look at what scientists have to say about their religious beliefs and what might be revealed by scientific studies of spirituality. This program is part of the Big Ideas Series, made possible with support from the John Templeton Foundation. The World Science Festival gathers great minds in science and the arts to produce live and digital content that allows a broad general audience to engage with scientific discoveries. Our mission is to cultivate a general public informed by science, inspired by its wonder, convinced of its value, and prepared to engage with its implications for the future.

The perfect merger of academic rigor and contemporary thinking has come together in the concept of iSchools, which give practical consideration and interesting learning opportunities to the most relevant issue of our time: information. So far there are over 50 worldwide iSchools; a global pool, like bitcoin for academia. The March 2014 conference was held in Berlin and the March 2015 conference will be at UC Irvine. With higher education under reinvention pressure from all directions, the possibility of making institutional learning relevant again cannot be underscored enough. iSchools are the perfect venue to take up not just the practical agenda within the information technology field but also the theoretical, philosophical, and societal dimensions of the impact of information technology. There have started to be some conferences regarding ‘big data theory’ (Theory of Big Data, University College London, Jan 2015), and a calling out of the need for ‘big data theory’ (Big Data Needs a Big Theory to Go with It, Scientific American, Rise of Big Data underscores need for theory, Science News). These efforts are good, but mostly concern having theory to explain the internal operations of the field, not its greater societal and philosophical effect. In addition to how ‘big data theory’ is currently being conceptualized, an explicit consideration of the general theoretical and social impact of information technology is needed. Floridi’s distinction re: philosophy of information is apt; the main focus is how the field changes society, not the internecine methods of the field. Research Agenda: Contemporary Information Technology Theory Studies Here is a thumbnail sketch of a research agenda for Contemporary Information Technology Theory Studies. Early examples of topics taken up at institutes and think tanks (like Data&Society) are a good start and should be expanded and included in the academic setting. A more appropriately robust agenda will consider the broad theoretical, social, and philosophical impact of the classes of information technology below that are dramatically reshaping the world, including specifically how our ideas of self and world, and future possibilities are changing. Research agenda: (1) Big Data (big data, smart data, personal data, group data); (2) Blockchain Technology (Institute for Blockchain Studies); (3) The Brain as an Information Technology (computational neuroscience, connectome, in-silico simulation, cognitive enhancement); (4) Smartcity, Connected World, Self-driving Vehicles http://futurememes.blogspot.com/2014/10/ischools-contemporary-information.html

Panel discussion moderated by Rose Regina, Dennis Schep, Luce deLire. Check out the notes and collaborative discussion here: https://medienpad.de/p/BlockchainedYourLife "We are defending our privacy with cryptography, [...]." (Hughes 1993) 1) ''What problem is it that cryptocurrencies try to solve?'' Fasten your seatbelt. In the first part of the event, we will hear about the historical origins and current political trajectories of cryptocurrencies and blockchain technology. We will receive a cryptocurrency crash course. We will engage in a cryptomaterialistic perspective on the metaphysical baggage cryptocurrencies come with. We will contextualize them within a set of larger scale political stakes (property, atheism). We will hear how these issues manifest in technology and its subjects. We will investigate the reinscription of pre-existing dominance and coercion by and through anonymous transaction, the monetization of data and the lack of undo buttons. 2) ''Are these the relevant problems?'' Has 'bitcoin' merely re-invented capitalism? Do 'smart contracts' rewire the notion of property? We will discuss these and whatever else you bring. We hope to come to think of some concrete actions. For this purpose, we might decide to break up into smaller groups. "The point is not to convert the inassimilable into the assimilable [nor to hedge and keep it inassimilable], but to challenge those regimes that require assimilation to their own norms."" (Butler 2012) Rose Regina Lawrence is the Digital Security Coordinator at Tactical Tech, a global non-profit network of activists, technologists and engaged citizens. Dennis Schep is a freelance cultural critic and literary scholar, based in Berlin. Luce deLire is a philosopher, currently on sabbatical from Johns Hopkins University.

A professor of philosophy at Ruhr University in Bochum, Germany, since 1976, Bernhard Waldenfels has written books about phenomenology, dialog theory, and structures of behavior. He was co-founder and vice president of the German Society for Phen omenological Research from 1970 to 1976 and president from 1994 to 1996. He also was a member of the scientific board of the College International at Paris from 1990 to 1998 and has been on the advisory board of the Institute for Genocide Studies at the University of Bochum since 1994. In this talk, response and trust will be presented as two central motives of a responsive ethics, which goes against every sort of communicative ethics orientated merely toward common aims and general norms.
