#TFTS (The Field They Say) --- SynTalk Album

SynTalk thinks about Vacuum and asks why is there something rather than nothing? Is empty space really empty? Does vacuum exist in the natural universe or is it merely a theoretical abstract conception? Is absolute vacuum possible? The concepts are derived off / from Hindu thought (eternal recurrence), Bible (genesis, void), Aristotle, Newton, Einstein, Copenhagen interpretation, Sommerfeld (fine structure constant), Maxwell, Heidegger (PEQ), Casimir (pair production), Biermann (solar wind) and Parker (solar wind model), among others. We marvel at the beauty of nature via CMBR, pole wandering (did dinosaurs die because of this?), magnetic reconnection, cosmological constant, dark matter / energy, dipoles, plasma (a la fire?), and absolute zero. How virtual particles come into ‘being’. What is happening in upper atmosphere (~70,000 kms above earth)? What does an ‘agitated’ sun do to earth’s atmosphere? Whether the laws of causation break down with quantum mechanics and sub-micron distance scales. How do neutrinos / muons reach us via empty space? Has Quantum Field Theory (QFT) left us in a state of limbo, and do we need to reformulate our conception of God? How empty space is bubbling. How would a ride to the sun be? The SynTalkrs are: Prof. Sunil Mukhi (particle physics, IISER, Pune), Prof. Kuruvilla Pandikattu (philosophy & theology, Jnana-Deep Vidyapeeth (JDV), Pune), & Prof. R.V. Reddy (plasma physics, Indian Institute of Geomagnetism, Navi Mumbai)

#TVAABP (The Vacuum As A Bubbling Place) --- SynTalk

SynTalk thinks about the act and the modality of naming ourselves and the (undifferentiated flux of the) world around us, & constantly wonders whether the world gets created when we name it. The concepts are derived off / from Panini, Frege, Russell, Premchand, Zipf, Searle, Kripke, & Probal Dasgupta, among others. Are variables or pronouns (‘this’ & ‘that’) or verbs born before the names? What cannot be named (what is between green and blue?), and is the process of naming ever complete? How a massive chunk of the world cannot be named. How is the process of naming different for a computer compared to a human being? Is naming or un-naming a neutral process? Why it is essential to name a musical note (why Re, Komal Re, & Ati-Komal Re?). How the cognitive significance of a name tells us something about frequency of occurrence. Is it possible to experience the musical notes without knowing the names of the notes? Does the object or the new born child suggest its own name, and how does baptism (or naming samskara) happen? How arbitrary is naming, and what do conventions, programming aesthetics, gestures, & culture have to do with it? What role does a neither-accepted-nor-rejected legacy play in the process of naming? How names transfer during language contact? How names represent the world from a trans-historical perspective? Can names be equated to a cluster of descriptions or are their modal profiles different? How we can name by not naming (say in taboo, euphemisms, ellipsis). Are names links between two or more face to face ‘pointing’ interactions? How does one discretize a (variably grained) conceptual world? How all Proper Names need not be proper nouns (what is water?). How Named Entity Recognition (NER) is central to the process of machine translation or transliteration, & how does one (generally speaking) shift from ‘low gaze’ to ‘high gaze’ to interpret the world? How names are not nouns but noun-phrases? Does sign language need to have names? Are names independent of language? Can you guess someone’s name by looking at her? The links between names, horses, feminist movement, caste system, homonymy, & globalization. How short will names get in the future? The SynTalkrs are: Prof. Pushpak Bhattacharyya (computer science & engineering, IITB, Mumbai), Dr. Girish Nath Jha (computational linguistics, JNU, Delhi), & Dr. Avinash Pandey (linguistics, Mumbai University, Mumbai)

#TNOAN (The Name Of A Name) --- SynTalk

SynTalk thinks about the dynamic nature & origins (since the big bang) of  fundamental & emergent forces in the universe. Was there only one force at the time of big bang? How did human beings first recognize & understand both the forces of nature (shamanism, magic, storms, lightning) and the forces more in their control (combat, weapons, hunting, push & pull)? The concepts are derived off / from Aristotle, Galileo, Laplace, Newton, Halley, Oersted, Faraday, Maxwell, Mach, Bohr, Planck, Einstein, Schrodinger, Heisenberg, Higgs, Max Jammer, & Karplus / Levitt / Warshel (2013 Chemistry Nobel Prize winners), among others. How is the world held together by the various forces? What exactly is a force field? Can there be force without matter (Yes)? Does matter create its field, or can a field be its own source? How to think of Maxwell’s equations in ‘free space’, and why we need matter (as sources for (say) microphones & radio)? How do forces act at a distance? Why do we try to create early universe conditions in large colliders, and study strong & weak forces? How did the forces separate (gravitation, electromagnetism, weak & strong forces, in that order) as the universe cooled down? Why don’t bodies simply move in a straight line, and links with the concept of ‘natural motion’? Is it (even) possible to know why forces exist? Is Big Bang the new ‘prima mobilia’, and how much more do we conceptually know about forces now? How do strongly interacting  (uncertain) electrons / atoms get confined in a classical body, and links with concepts of multiscaling (QM/MM; Quantum Mechanics/Molecular Mechanics) and the mesoscopic world? Why an electrical circuit is difficult to understand in terms of electromagnetic field theory. How forces bind parts together and why / how a different whole sometimes emerges? How the degrees of freedom get frozen as the number of bodies increase. Why did Bohr’s premise of simply quantizing angular momentum did not work for many-electron atoms (beyond hydrogen-like atoms)? Link of the grey zone (‘interface region’) between quantum mechanics & classical mechanics with drugs, proteins, buildings, brain, cricket ball, polymers, spark plug, steering wheel, effective theory, & wave-particle duality. How does a magnet defeat the earth and pull a piece of iron, and its links with gauge theory (with all three forces, except gravity) and the possibility of  gravity as an entropic or emergent force? Are market, political, or life forces similar entropic forces? Why is gravity difficult to unify with the other forces? Has ‘force’ replaced ‘energy’ since mid 19th century (after the energy-ists)? Are a different set of forces likely to govern dark matter and dark energy? Is force just a defined concept and not purely fundamental? The SynTalkrs are: Prof. S. D. Agashe (electrical engineering, history & philosophy of science, IITB, Mumbai), Dr. Sourav Pal (quantum chemistry, NCL, Pune), Prof. Sreerup Raychaudhuri (particle physics, TIFR, Mumbai).

#TFOFA (The Fields Of Forces Around) --- SynTalk

SynTalk thinks about (real, virtual & abstract) boundaries and wonders why some boundaries are crisp while others are fuzzy (fixed centers but no boundaries). We discuss boundaries and borders using concepts from computer science, geopolitics, defence studies, philosophy, mythology, linguistics, statistics, biology, & mathematics. The concepts are derived off / from Zeno, Darwin, Turing, Chebyshev, Korzybski, Saadat Hasan Manto, & Feynman, among others. Is the cell membrane (say) a boundary, and how does it help the organ know about the world? How does a (physical) boundary of pebbles operate ‘within’ the river Ganges? How there is a robust (crisp) line separating the solvable and the unsolvable. How is the notion of the border different from the real border (in the Gaza ‘brown strip’)? We explore the fascinating journey of ‘empires with frontiers’ to ‘nation states with militarized borders’ over the last several centuries. Is there ultimately a certain ‘life force’ behind creation of real & virtual boundaries? How does one trust a neighbor? What is the nature of boundaries around ‘languages’ & ‘species’? How do statistical systems have upper and lower bounds, and how is it possible to predict the reliability of a system with a ‘confidence interval’? Is a statistical mean similar to the center of a set? Is there a gradual inevitable dissolution of the definitiveness of borders, even if borders have been paid for in blood? How an emergent or an imposed hierarchy introduces the vertical and distorts the lateral? What is no man’s land? Is there a convexity (with inside and an outside) for a malware? How is the notion of the border, mediated by the colonial experience of certain countries? We invoke themes illustrated by, among others, Israeli-Palestinian, Indo-Pakistan, Dutch-German, Indo-Myanmar, Chinese-North Asian borders. How are the maritime borders different? What is the long term future of the borders in context of the universal human condition? The SynTalkrs are: Commodore C. Uday Bhaskar (defence studies, Society for Policy Studies, New Delhi), Prof. K.P. Mohanan (linguistics, critical thinking, IISER, Pune), Prof. Sanjeev V. Sabnis (probability, IITB, Mumbai), & Prof. R.K. Shyamasundar (computer science, TIFR, Mumbai)

#TBBAF (The Borders Boundaries And Fences) --- SynTalk

SynTalk thinks about the unidirectional nature of time and wonders if time is a separate ‘category’ at all. We dip into cosmology, computer science, neuroscience, quantum physics, & philosophy. We wonder whether time is essentially a (background) variable. Is time nature’s way of preventing everything from happening at the same time (a la Wheeler)? The concepts are derived off / from Newton, Fred Hoyle, Maxwell, Dirac, Planck, Godel, Bohr, Einstein, H G Wells, Wheeler, Feynman, Prigogine, Landauer, Roy Kerr, Everett, Novikov, & Zeldovich, among others. How has the notion of time changed with digital watches? What is ‘logical time’, & the importance of multiple systems synchronizing with each other? What would happen if we hit an electron with a hammer? Do we get ‘it from bit’, and what is the possible link of time with (quantized) information? Can neurons be thought of as being probabilistically synchronized oscillators? We also discuss the concept of Planck’s time as the fundamental unit, & the resultant notion of whether time is discrete or continuous. What is the link between causality and time? We discuss the fascinating links of time with thermodynamics, entropy, ‘action at a distance’, & closed / open systems. What would happen, surprisingly, if a hot star were to be connected with a cold star via a conducting wire? The nature of neurological time, and its links with octopuses, crabs, speeding cars, a ‘cache of situations’, & reflex actions. How do (memory) space & time tradeoffs impact computer algorithms? Can time be lost? How ‘branching time’ creates possible worlds that are not known a priori? Is time travel possible (via a worm holes), and does it need a conception different from ‘state-based’ time? Do animals ‘have’ time? The SynTalkrs are: Prof. Jayant V. Narlikar (astrophysics, IUCAA, Pune), Prof. Krithi Ramamritham (computer science, IITB, Mumbai), & Prof. Sisir Roy (theoretical physics, NIAS, IISc, Bangalore).

#TAOT (The Arrows Of Time) --- SynTalk

SynTalk thinks about the deep historical and ongoing interrelationships between (the all pervasive & incessantly productive) images, and concepts & words. We make the widely sweeping journey from ancient rock art to the Coca-Cola logo to images on monitors in hospitals, to possible futures (say) a 1000 years out. The concepts are derived off / from ‘Lingo Dev’, Aristotle, Hippodamus of Miletus, Freud, Saussure, Peirce, Derrida, Foucault, Le Corbusier, McLuhan, Debord, & Baudrillard, among others. Can concepts or conceptual entities come to be without language? What are the links between rock art, and speech, script, words, entoptic phenomena, induced phosphene images, catenary curves, ‘scene of experience’, & language? Do 100,000+ years old rock arts provide a promising clue to how meaning gradually emerged from the pre-conceptual pre-representational ‘cauldron’? Are letters and pictures interchangeable, and have they always been so? How images come from very ancient times and how they thrust forward from without and from within? Do we dream in images? Is there any logo which is non iconic? How the core pursuit of advertising is to give form to an abstraction. How does advertising tackle different media, & how an advertisement in the print necessarily needs to be ‘processed in the mind’? How do you create the concept of ‘Friday dressing’? How Jarawas (from Andamans) have come to use words from English or Hindi. Does extinction of languages lead to death of concepts, & the attendant phenomena of amnesia and aphasia? We discuss Egyptian, Mesopotamian, Phoenician, Greek, & Chinese scripts. How icons (& further images, diagrams & metaphors), index & symbols are different from each other? How is a notion different from a concept? Is there conflict and cooperation always at play between images (of say, Batman, Hanuman, Manga, or Anime), & are images conquering the world? Where do specters and ghosts come from? Is there an incessant mass-ification of images (via ‘procession of the simulacra’) ongoing and ahead of us, & are images the long term future of language? Are images & meanings going to be increasingly crowd sourced in the future? Is a technology-driven ‘master narrative’ taking over the visual arts, cities, & forests, and is the ‘visual landscape’ shrinking? The SynTalkrs are: Dr. K. K. Chakravarty (art, public administration, Lalit Kala Akademi, Delhi), Santosh Desai (advertising, strategy, Futurebrands, ex-McCann-Erickson, Delhi), & Prof. Franson D. Manjali (semiotics, interdisciplinary, JNU, Delhi).

#TICAW (The Images Concepts And Words) --- SynTalk

SynTalk thinks about the interrelationships between wholes and parts in natural and conceptual systems, and wonders whether the part is inferred from the whole. Does a part (somehow) imply or expect the whole? The concepts are derived off / from Abhinavagupta, Newton, Kepler, Boltzmann, Boyle, Saussure, Turing, Manfred Eigen, P. W. Anderson, Chomsky, & Morris Halle, among others. In interactions between words, fundamental particles, molecules, cells, & phonemes, why are most combinations void? How do a finite number of parts create a dizzying array of wholes, and links with concepts such as historical contingency, surplus, entropy, sequencing, emergentism, & auto-catalysis? Why are transitions in biological, physical, ecological, social, and linguistic systems so tentative and statistical? Has the physics of the material world achieved a special kind of climax in the biological unit of life, & how the cell is not simply a bagful of chemicals. How the cell is both a part and a whole, & the context of cell division. Which is the most fundamental living part? How entropy comes about ‘only’ in systems of ‘many’ interacting particles. At what point can we start defining concepts such as pressure, volume, & temperature? Why certain molecular complexes self-emerge into functioning self sustaining evolving systems? Why literature does not simply describe the world, and how the non-existent also often make sense? In our daily linguistic behaviour, do we (fundamentally) use phonemes or words or sentences? How a word is a meaningful sequence of phonemes, and the similarities with gene sequencing; the difference between: ‘John killed the tiger’, & ‘the tiger killed John’. The sound patterns of language, & how any sound cannot come after one sound. Can one syllable be a whole in itself (bijakshara)? How a large chunk of the genome performs mundane functions, & discrimination results only from a handful of genes. Are carbon atoms in graphite and diamond identical in every single way, or do the atoms become something different? The links between rabbit’s horn, bureaucracy, multiverses, Lego toys, universal physical constants, Mesopotamian civilization, zebra, sky flower, existence, and time. The implications of an animal (whole) repeatedly developing into an animal (whole). How non linearity (in both deterministic and stochastic systems) is crucial for any emergent phenomena. Is the long term future of existence non local (a la ‘the ant colony as an organism’) and (potentially) altruistic? The intriguing prospect of new emergence as a result of the unprecedented ongoing meta-interactions, where parts (human beings) increasingly understand the emergent design of the whole? The SynTalkrs are: Dr. Rajnish K. Mishra (linguistics, philosophy, JNU, Delhi), Prof. B.J. Rao (biology, TIFR, Mumbai), & Prof. Sitabhra Sinha (physics, IMSc, Chennai).

#TWAP (The Whole And Parts) --- SynTalk

SynTalk thinks about theories & theorizing, while constantly wondering whether theories are explanatory as well as speculative (‘what-if’). Are all theories, in a sense, artistic creations and inventions (rather than discoveries)? Can we take the human out of the equation? The concepts are derived off / from Euclid, Newton, Leibniz, Alexander Pope, Robert Hooke, Boole, Faraday, Maxwell, Gauss, Hilbert, Godel, Bourbaki, Abraham Robinson, Weinberg, Stanley Fish, Lawvere, & Stephen Wolfram, among others. How all physical theories have a desire to predict & look into the future. How mathematical theories, however, do not need to predict and have no role for evidence. Further, how theories in literature are an attempt to explain the process of interpretation? Are there theories that are finished pieces of work (test: when all true statements are provable)? Are some theories destined to be incomplete? Will we ever have a complete theory for poetry? Is all of mathematics just a theory? Do all theories (real numbers, classical mechanics) have limits? Is everything that is there to be known about a triangle now known? How a theory comes to be conceived in areas far far removed from available knowledge, via a leap of imagination or (even) an act of faith. How ‘non-logical axioms’ when put into the magical black box of ‘logic’ churns out a list of ‘provable statements’. How crystalline & elegant axioms are often identified after years of calculations. Can we, for instance, axiomatize the notion of space or theorize about some currently ill understood domains of gravitation at the largest scale? How logic specifies a grammar for construction. How double negation may not work in some systems (what is not true is not necessarily false). May the idea of the observable or the ways of seeing itself be theoretical constructions? Can finished theories have parallel ways of thinking (say, lines of force, fields of force, or electromagnetic potential)? The links between theoreticity and abstraction, & is (even) man a theory (‘the proper study of mankind is man’?). Are (electrical) circuit laws completely autonomous of the fundamental Maxwell equations? Are Laws the robe and Theory the wardrobe? The links between dog star, functor, earthquake, QCD, ‘mortal grossness’, Nile floods, fluxions, video games, chariot, White Males, synthetic differential geometry, love-dove-&-shove, & the salt doll. How theories wax & wane with the consensus and dissensus of interpretive communities. Are there universal truths? Can we simulate the answer to any question with extremely efficient computation without theories? Will theory itself come to an end in the long run? The SynTalkrs are: Dr. Partha Pratim Ghosh (mathematics, ISI, Tezpur), Prof. Pramod K. Nayar (literature, University of Hyderabad, Hyderabad), & Prof. Urjit A. Yajnik (physics, IIT Bombay, Mumbai).

#TEOT (The Everything Of Theory) --- SynTalk

SynTalk thinks about errors, while constantly wondering if they are innately hardwired into nature. Are error free domains possible or desirable? Would we stop making history if there were to be an error free world? The concepts are derived off / from Gnosticism, Aristotle, Alhazen, Galileo, Kepler, Thomas More, Lord Kelvin, Heidegger, Cioran, Gödel, Piaget, John Bell, & Tony Hoare, among others. Is all truth temporal? The difference between systematic (in one direction) and random (in both directions) errors with respect to the true value. Do things fail in the (non-human) natural world or they just ‘happen’? Is failure about an unfolding process while errors are more punctual? How (measurement) errors are inextricably linked to the notion of standard conception and expectation. Is there a trade-off between safety (not making mistakes) and liveness (making progress) for reactive systems (that interact with the environment)? How did a perfect Being create an imperfect world, and is it possible to have a ‘theology of failure’ (via, say, the demiurge)? How we pose the existence of a creator via notions of making, design or performance of the world (as an object). Is it likely that (software) modules that are individually correct give an error when put together? How in languages that are self referential & expressive it is impossible to prove if a program is correct. How some flawed universal notions can be much more intuitive. The (deeply counterintuitive) equivalence of uniform motion and rest. How there is often a striking similarity between students’ flawed conceptions and the history of ideas. Is limited experience the main source of errors? How computer programs non monotonically learn from experience, and the accompanying process of belief revision? Is consistency the virtue of an ass? What is the opposite of failure? Does one experience profound existential nothingness when one encounters failure? How (fortunately?) utopias – the perfect social & political models of the world – fail, and links with expectations and game theory? The links between ‘the world going to the dogs’, violent movement, bugs, chess, God, invariants, flight controllers, voting, winners & losers, exponential blow up, theory of vision, clocks, the original sin, bicycle, & the verifying compiler. Is it possible that there are ‘hidden variables’ in the physical world that makes even the quantum world completely certain? Would becoming perfect be the end of everything, & should we stay imperfect? The SynTalkrs are: Dr. Costica Bradatan (philosophy, Honors College, TTU, Texas), Prof. Arvind Kumar (physics, Centre for Excellence in Basic Sciences, ex-HBCSE TIFR, Mumbai), & Prof  G. Sivakumar (computer science, IIT Bombay, Mumbai).

#TEMAF (The Errors Mistakes And Failures) --- SynTalk

What comes first - matter or space or time? What is the structure of space? Why did Paul Cezanne go 'flat'? How did Picasso turn the artistic conception of space on its head with cubism? Is there a link between colour and space? What is it like to be in Matisse's The Red Studio? What happens when you walk into a room that you have not been in before? Are there specific neurons in your brain for every space that you have ever been to? How do place cells within the hippocampus represent the physical space as a cognitive map? Is space the same everywhere in the universe? Is it possible to represent empty space? How does an artist create the pictorial space on a 2-dimensional canvas? Is the perception of space always relative to matter (& objects)? Is episodic memory anchored in space (the 'where')? What is space like at sub atomic scales? Does nature really have more than 3 dimensions? Has theoretical physics completely missed incorporating gravity of all the matter in the universe? Is matter essentially primary, time derived, and space essentially relational? SynTalk thinks about these & more questions, about the manifested space around and within us, using concepts from physics (Prof. C.S. Unnikrishnan, TIFR, Mumbai), art (Atul Dodiya, Mumbai), and neuroscience (Dr. Sachin Deshmukh, IISc, Bangalore).

#TROS (The Representation Of Space) --- SynTalk

Have you ever received a partly garbled email? Might mixtures be made of mixtures? Are you a separate being? Do you stand ‘in’ history? How is coming-together different from mixing? Is it possible to separate out the constituents from a mixture without knowing what they are? Why does the chiral environment of the body matter? How difficult is pure separation, & why? Can separation or decoding be done in real time? Is separation trivial after mixing? Do different groups constrain individual identities differently? Can partitions be constructions? Why is vote-to-seat conversion so difficult in elections? Does noise have statistical properties? How are filters designed? Do signals always have a continuity property? Why is it so difficult to factorize into two large prime numbers? Can individuality be dissolved (in, say, a mob)? What is the opposite of a mob? Can certain systems be made nearly impossible to partition? What is the future of separations and partitions: Will quantum computing force change in encryption? How would enantiomers be separated? Would entry and exit barriers be lower in several contexts? SynTalk thinks about these & more questions using concepts from chemistry (Prof. Ravi Bhushan, IIT Roorkee, Roorkee), mathematics & statistics (Prof. Rajeeva L. Karandikar, Chennai Mathematical Institute (CMI), Chennai), & social sciences (Prof. Gurpreet Mahajan, JNU, New Delhi). Listen in…

f(q) = Is soil a definitive sign of life? (#TCAFG)

SynTalk is a freewheeling interdisciplinary talk show with a philosophical approach to understanding the world from a long term perspective.
