Why Physicists Are Saying Consciousness Is A State Of Matter, Like a Solid, A Liquid Or A Gas — The Physics arXiv Blog
There’s a quiet revolution underway in theoretical physics. For as long as the discipline has existed, physicists have been reluctant to discuss consciousness, considering it a topic for quacks and charlatans. Indeed, the mere mention of the ‘c’ word could ruin careers. That’s finally beginning to change thanks to a fundamentally new way of thinking about consciousness that is spreading like wildfire through the theoretical physics community. Today, Max Tegmark, a theoretical physicist at the Massachusetts Institute of Technology in Cambridge, sets out the fundamental problems that this new way of thinking raises. Tegmark’s approach is to think of consciousness as a state of matter, like a solid, a liquid or a gas. He goes on to show how the particular properties of consciousness might arise from the physical laws that govern our universe. In 2008, Tononi proposed that a system demonstrating consciousness must have two specific traits. Tegmark does not have an answer.

International Consciousness Research Laboratories | Furthering the establishment of a Science of the Subjective Emerald Tablet An imaginative 17th century depiction of the Emerald Tablet from the work of Heinrich Khunrath, 1606. The Emerald Tablet, also known as the Smaragdine Table, or Tabula Smaragdina, is a compact and cryptic piece of Hermetica reputed to contain the secret of the prima materia and its transmutation. It was highly regarded by European alchemists as the foundation of their art and its Hermetic tradition. Textual history[edit] The text of the Smaragdine Tablet gives its author as Hermes Trismegistus ("Hermes the Thrice-Greatest"), a legendary Hellenistic[1] combination of the Greek god Hermes and the Egyptian god Thoth.[2] Despite the claims of antiquity, it's believed to be an Arabic work written between the sixth and eighth centuries.[3] The oldest documentable source of the text is the Kitāb sirr al-ḫalīqa (Book of the Secret of Creation and the Art of Nature), itself a composite of earlier works. The tablet text[edit] Newton's translation[edit] Theatrum Chemicum translation[edit] C.G.

Quantum mysteries John Gribbin For seventy years, physicists have worried about what quantum mechanics means. They can use quantum physics, to be sure; witness the successful designs of lasers and computer microchips, and the understanding of molecules that makes genetic engineering possible. In fact, few physicists worry about such things. The archetypal example of the quantum mysteries is the "experiment with two holes", where the measured position of a single electron that passes through two holes in a screen can only be explained in terms of the wave function travelling through both holes at once and interfering with itself. Imagine that we have a source which will emit a single quantum particle in a random direction (ordinary radioactive nuclei do exactly this, so there is nothing special about the source). So far, simple enough. But a giant leap in what might be called quantum philosophy has recently been taken by the American physicist John Cramer. It works like this.

Vitamin D: evolutionary, physiological and... [Curr Drug Targets. 2011 'Collision Course' in the Science of Consciousness: Grand Theories to Clash at Tucson Conference | Deepak Chopra by Deepak Chopra, MD and Stuart Hameroff, MD, Anesthesiology, Psychology, Center for Consciousness Studies, The University of Arizona, Tucson, Arizona The nature of consciousness, the reality it conveys, and our place in the universe remains unknown. Since ancient times, two types of views have approached these problems. In Western science and philosophy, consciousness is strictly a by-product of brain activity, the reality it perceives is not to be trusted ('Plato's cave', Descartes' 'brain-in-a-vat', Dennett's 'multiple drafts'). On the other hand, in Eastern philosophy, consciousness is primary, the fundamental basis for reality. William James popularized consciousness at the turn of the 20th century, but behaviorist psychologists then focused on quantifying brain function. Around the early 1990s, great scientists Francis Crick, Sir Roger Penrose and others seriously addressed consciousness. In his 1989 book "The Emperor's New Mind", Sir Roger Penrose took a quite different approach.

Rethinking the Placebo Effect: How Our Minds Actually Affect Our Bodies by Maria Popova The startling physiological effects of loneliness, optimism, and meditation. In 2013, Neil deGrasse Tyson hosted a mind-bending debate on the nature of “nothing” — an inquiry that has occupied thinkers since the dawn of recorded thought and permeates everything from Hamlet’s iconic question to the boldest frontiers of quantum physics. That’s precisely what New Scientist editor-in-chief Jeremy Webb explores with a kaleidoscopic lens in Nothing: Surprising Insights Everywhere from Zero to Oblivion (public library | IndieBound) — a terrific collection of essays and articles exploring everything from vacuum to the birth and death of the universe to how the concept of zero gained wide acceptance in the 17th century after being shunned as a dangerous innovation for 400 years. Among the most intensely interesting pieces in the collection is one by science journalist Jo Marchant, who penned the fascinating story of the world’s oldest analog computer. Donating = Loving

Consciousness Might Emerge from a Data Broadcast Quantum physicist Wolfgang Pauli expressed disdain for sloppy, nonsensical theories by denigrating them as “not even wrong,” meaning they were just empty conjectures that could be quickly dismissed. Unfortunately, many remarkably popular theories of consciousness are of this ilk—the idea, for instance, that our experiences can somehow be explained by the quantum theory that Pauli himself helped to formulate in the early 20th century. An even more far-fetched idea holds that consciousness emerged only a few thousand years ago, when humans realized that the voices in their head came not from the gods but from their own internal spoken narratives. Not every theory of consciousness, however, can be dismissed as just so much intellectual flapdoodle. During the past several decades, two distinct frameworks for explaining what consciousness is and how the brain produces it have emerged, each compelling in its own way. This neural buffer does more than process recent sensory inputs.

7th Grader mimics Nature 13 year old copies Nature to Improve Solar Performance Thirteen year old Aidan Dwyer was walking in the woods in Upstate New York in the winter and noticed a spiral pattern to tree branches. Aidan realized the tree branches and leaves had a mathematical spiral pattern that could be shown as a fraction. Aidan's backyard in Northport, NY. The 7th grader next wondered why nature used such a pattern? Aidan discovered that the Fibonacci pattern helps deciduous trees, in higher latitudes, efficiently track the Sun and collect the most sunlight even in the thickest forest, on the cloudiest days. The American Museum of Natural History has awarded Aidan a Young Naturalist Award for 2011. See the detailed description of his discoveries on the Museum's website: * In late 2012, early 2013, Aidan builds a larger model: Postscript: Many have questioned why Aidan did not measure power output from the solar cells, instead he only measured voltage, without a load attached ("open circuit").

Introduction to quantum mechanics Non-technical introduction to quantum physics Many aspects of quantum mechanics are counterintuitive[3] and can seem paradoxical because they describe behavior quite different from that seen at larger scales. In the words of quantum physicist Richard Feynman, quantum mechanics deals with "nature as She is—absurd".[4] Features of quantum mechanics often defy simple explanations in everyday language. One example of this is the uncertainty principle: precise measurements of position cannot be combined with precise measurements of velocity. Quantum mechanics helps us understand chemistry, because it explains how atoms interact with each other and form molecules. History[edit] Maxwell's unification of electricity, magnetism, and light in the 1880s led to experiments on the interaction of light and matter. Evidence of quanta from the photoelectric effect[edit] Hot objects radiate heat; very hot objects – red hot, white hot objects – all look similar when heated to the same temperature.
