[#23]  Time and Reality

Last week I wrote about language weaving a virtual reality from us, through the use of concepts that tend to dress up all that  we experience.  Naked reality remains largely hidden for us, except perhaps for a split second after waking up, while we are putting on our conceptual clothes, or in moments of great surprise.  Time is the greatest concept of all, hiding . . . .

[#22]  Language, Concepts and Reality

The origin of language, a few hundred thousand years ago, was also the origin of virtual reality: the ability to communicate about the not-here, not-now, not-you.  And in the process we learned to talk to ourselves, entertaining fantasies, spelling out hope and fear.  Since then we've rarely stopped doing so.

[#21] Novelty: in Matter, in Knowledge of Matter, and in Knowledge of Knowledge

The last four days I spent in Atlanta, at Georgia Tech, visiting Eric Smith, the lead author of a pathbreaking book on the Origin of Life.  A couple years ago, I convinced Eric to write a book with me to extend his views to more general origins questions, from the origin of the Universe, to the origin of life, to the origin of consciousness -- or you could say, the origins of the Universe, life, and the ability to ask these questions.

[#20] Teaching Reality: Quantum Mechanics

Last week I wrote about teaching physical reality in a more honest way in high school, starting with the best theory we have of gravitation, general relativity.  The other pillar of fundamental physics, also discovered early in the 20th century, is quantum mechanics, which is even more fun to teach without using mathematics.

[#19] Teaching Reality: Starting with Gravity

In high school, students are taught 19th century physics, two centuries out of date.  Mechanics and gravitation appear as it was known in the late 17th century, and electricity and magnetism as it was known in the early 19th century.  This is a shame: it would be like teaching pre-Darwinian biology!

[#18] Singularities as Hints, Unrelated to Reality

Predictions of technological singularities are as wrong as predictions of singularities in physics, which have always been the harbingers of new physics.  When any prediction leads to division by zero, we can be sure that new laws or regularities will set in.  What singularities are good for is . . .

Synopsis of Li Zhaoping's YHouse Luncheon Talk 11/9/2017

On Thursdays at noon Yhouse holds a lunch meeting at the Institute of Advanced Study, in Princeton. The format is a 15 minute informal talk by a speaker followed by a longer open-ended discussion among the participants, triggered by, but not necessarily confined to, the topic of the talk.  In order to share I am posting a synopsis of the weekly meetings.

Synopsis of Li Zhaoping’s Yhouse Luncheon talk 11/9/17

Presenter: Zhaoping Li (University College London)

Title: Looking And Seeing In Visual Functions Of The Brain

Abstract: "Vision is a window to the brain, and I will give a short introduction and demonstrate that it can be seen as mainly a problem of "looking and seeing", which are two separable processes in the brain.  Understanding vision requires both experimental and theoretical approaches, and to study the brain using our own brains have its peculiar difficulties."

Present: Piet Hut, Olaf Witkowski, Yuko Ishihara, Arpita Tripathi, Li Zhaoping, Michael Solomon

Li Zhaoping studied physics in China before getting her PhD in Brain Science at Cal Tech and coming to the IAS 27 years ago as a post doc working then on the olfactory system. She currently works at University College London on vision, with an emphasis on computer science and on artificial and natural intelligence. She began with the statement that “The Eyes are the window to the Brain”...

[#17] First Mist in the Universe

When the Universe was ten microseconds old, mist started to form in the Universe.  By the time the Universe reached the age of a hundred microseconds, the mist was complete: the Universe was drenched in tiny quark-gluon droplets that would become the protons and neutrons in the nuclei of the atoms that our bodies are built out of.

Synopsis of Michael Solomon’s YHouse Lunch talk 10/26/17 Cancer As A Metabolic Disease

TITLE:  Is cancer a metabolic disease caused by mitochondrial dysfunction?

ABSTRACT:  For the past 40 years we have thought of cancer as the result of somatic mutations in nuclear DNA that either block tumor suppressor genes or unblock oncogenes resulting in malignant transformation.  But our success in understanding or in treating cancer has been sadly limited. Thomas Seyfried and others have made a strong case that, in fact, cancer results from the loss of the cell’s ability to obtain energy (ATP) via oxidative phosphorylation, resulting in the cancer cell’s reverting to more primitive metabolic pathways and fermenting glucose (and the amino acid glutamine) even in the presence of adequate oxygen (aerobic glycolysis).  This theory was originally suggested by Otto Warburg in the 1940’s, the so-called Warburg effect.  I will offer evidence supporting the possibility that malignant transformation in all cancer is a metabolic disease resulting from mitochondrial dysfunction and is not a genetic disease caused by nuclear DNA changes which occur secondarily.  This leads to alternative management strategies for cancer without toxic radiation or chemotherapy.....

Synopsis of Olaf Witkowski’s Consciousness Club Talk 10/25/2017

Abstract:  Information is found all across the domain of physics, seemingly retaining all its properties regardless of the media in which it is instantiated. Substrate-independence and interoperability made possible symbolic representations such as the genetic code, allowing for life to develop upon it. The next transition closed the loop by producing organisms increasingly aware of their environment. This eventually led to human life, capable of learning the underlying principles that created it, with the invention of language and science.
      I focus my research on collective cognition, which one can see as the informational software to life's physical hardware......

[#16] Evolution of Parts and Wholes in Life-Like Entities

In nature, culture, and technology, surprising novelty has appeared as products of ongoing evolution.  Many new forms  of organization are themselves remarkably life-like.  A key aspect is that their building blocks evolve together with  their structures and processes -- and so do we, as building blocks of many overlapping societal systems.

Synopsis of 9/30/17 YHouse Lunch talk by Ohad Nachtomy

Title: The Psycho-Physical Lab

Ohad is working on a book with this title about the Mind/Body problem in philosophy and links to the practice of Yoga.  This book is not intended as an academic contribution to research but for a broader audience.  His coauthor, Eyal  Shifroni, Has been a yoga teacher for years.  He argues that reflective yoga practice goes beyond health, but offers a way to engage body and mind to train each other.  We use our physical abilities and limitations to train our mental capacities, and vice versa, to improve each.  Reflective practice is essential to development.  He emphasizes practice with less effort and more attention.  This does involve posture and breathing exercises, but to what purpose?  We cannot make sense of mental states without referring to our physical bodies.  Body and Mind are interconnected.  We train the body through reflective processes and improve the whole being......

SYNOPSIS OF LIAT LAVI'S IAS LUNCHEON TALK ON SEPT. 28, 2017

In my talk I will present the account of understanding I am developing under the title of 'expectationalism'. The account draws heavily on Jamesian Pragmatism and the thought of Heidegger and Merleau-Ponty. Its central premises are: 1. That the meaning of something is its consequences, and to understand something is to grasp its consequences. and 2. That expectations are not some internal content, but are rather actualized by our bodies. I will link this account with contemporary approaches in cognitive science and philosophy of mind, and suggest that if the account is correct this implies that strong AI is possible and that limited instances of it already exist......

[#15] Computer Simulations as Dynamical Metaphors

To point out something really new, we can use a quick metaphor or we can take our time to tell a story that is richer in details.  A computer simulation can do both: pointing out a few salient characteristics of a situation as a kind of metaphor, and then letting it run to dynamically produce its own narrative.

Synopsis of Randall Beer’s YHouse Luncheon talk 10/19/17

Abstract: "I will briefly describe two intertwined research programs. The first concerns issues of embodiment, situatedness and dynamics in understanding how an animal's behavior arises from the interaction between its nervous system, its body and its environment. Specifically, we use genetic algorithms to evolve model brain-body-environment systems and then analyze their operation using the tools of dynamical systems theory and information theory. This approach has been applied to a wide variety of behaviors, including locomotion, action-switching, learning, categorization, selective attention, and referential communication. The second concerns the organization of minimal living systems and its consequences. Specifically, we analyze  persistent spatiotemporal entities in cellular automata models from the perspective of autopoiesis and enaction. We identify the local processes that underlie

Synopsis of Consciousness Club talk Oct. 11, 2017 by Yuko Ishihara

Speaker:  Yuko Ishihara
Title:  Consciousness: not a “thing” but a “place”.
We Work, 110 E 28th Street NYC, NY.

Abstract:  Modern western thought has given consciousness a special place in the understanding of human beings. According to Descartes, it is the fact that we are "thinking things" that sets us apart from unconscious things like a desk or a pen. While scientists and philosophers today disagree with Descartes on what constitutes the nature of the thinking thing, most people agree on the basic Cartesian assumption: that consciousness is a kind of "thing."
But can we not question this assumption? Putting aside all theories, our direct experience teaches us that consciousness does not primarily appear as a thing. Rather, it appears more as a ground or "place" wherein our experience occurs. Drawing on insights from twentieth-century philosophers like Martin Heidegger and Nishida Kitaro who developed a philosophy of place, let us think together about what it really means to understand consciousness not as a "thing" but as a "place." Perhaps such ideas can open doors towards a better understanding on the nature of consciousness.

[#14] Kindred Spirits: Meeting Carl Pabo

This weekend I flew out to San Francisco, to meet Carl Pabo.  We have only met a few times since we first met 12 years ago, but we are clearly kindred spirits.  We both want to radically change the way our society deals with knowledge, and after a few decades of exploration, we each are in the process of building up an organization that aims at doing just that.  The difference is . . .

[#13] Experiencing Theory: The Gate To Understanding

Science is based on theory and experiment.  But to understand theory, we need to experience theory.  Unless we fall into an experience of mathematics, we cannot know what theory means, and we cannot compare theory and experiment.  In experiencing theory, I have encountered three very different levels of insight.
