Gould & Dennett

Reference: 100 years of Sri Aurobindo on evolution.

Stephen Jay Gould's retort to Dan Dennett Darwin's Dangerous Idea called The Pleasures of Pluralism:

Daniel Dennett devotes the longest chapter in Darwin's Dangerous Idea to an excoriating caricature of my ideas, all in order to bolster his defense of Darwinian fundamentalism. If an argued case can be discerned at all amid the slurs and sneers, it would have to be described as an effort to claim that I have, thanks to some literary skill, tried to raise a few piddling, insignificant, and basically conventional ideas to "revolutionary" status, challenging what he takes to be the true Darwinian scripture. Dennett claims that I have promulgated three "false alarms" as supposed revolutions against the version of Darwinism that he and his fellow defenders of evolutionary orthodoxy continue to espouse.......   more »

Augmented reality combines features of a virtual environment with the real world. Most often, the augmentation is visual, with a user sporting an eyepiece connected to a wearable computer and positioning equipment. By tracking where the user’s head is and what he is seeing, the computer is able to overlay graphics and/or text onto his vision.   more »

Attention-deficit hyperactivity disorder (ADHD) is considered the most common psychiatric disorder experienced during childhood. Some references indicate an incidence as high as 10% of American school-age children. Most references, however, place the incidence in this age group at around 2%–5%. Approximately 80% of children with ADHD continue to have symptoms of the condition as adolescents, and more than 60% of children experience symptoms as adults. If these estimates are correct, between 2 and 5 million adults who had ADHD as a child continue to be affected by the condition. Many adults with ADHD have not been diagnosed as such.   more »

Perhaps it is best if the twain between science and religion do not meet. Trying to engage science and spirituality in a dialog has a long and troubled history. The incommensurable narratives of matter and spirit they both tell have proven time and time again troublesome for reaching any common understanding. In fact, if science and spirituality do share something in common it is that they all too often accuse the other of totalizing a universal narrative that usurps all ways of looking at the world that are inconsistent with their own.

Religion and science each have their own fundamentalist practitioners who would reduce the world solely to accounts told in their holy books or biology text books. One can not easily imagine an encounter between science and religion in which some violent reaction would not be triggered. Worse perhaps then the violent confrontation between science and religion is when either one appropriates the narratives of the other for the purpose of furthering their own ideological concerns. In the case of religion one example would be in their use of science to justify creationism, while in the case of science such appropriation usually results in one of the just-so stories of origins or cultural analogs of natural selection that Neo-Darwinism tells....

This holds true also for any dialog one would wish to begin between integral yoga and science. It would perhaps be best to begin such a dialog by first exploring Sri Aurobindo's dialectic between yoga and culture and then to look for resonances with narratives told by credible scientist regards the dialectics of science and culture. Better yet, in Sri Aurobindo's own work one finds him at times also critically exploring the dialectic between science and culture. It would therefore seem best to arrive at a dialogic platform to engage science and integral yoga using their diffusion in the semi-permeable membrane of culture, rather then by a direct confrontation as a means to begin the conversation.    more »

A NASA spacecraft has taken the first-ever image of an avalanche in action near Mars' north pole. -- The High Resolution Imaging Experiment (HiRISE) on NASA's Mars Reconnaissance Orbiter took the photograph Feb. 19. The image, released today, shows tan clouds billowing away from the foot of a towering slope, where ice and dust have just cascaded down.

The camera was tracking seasonal changes on Mars when it inadvertently caught the avalanche on film. -- HiRISE mission scientist Ingrid Daubar Spitale of the University of Arizona was the first person to notice the avalanche when sifting through images.

"It really surprised me," she said. "It's great to see something so dynamic on Mars. A lot of what we see there hasn't changed for millions of years." ...   more »

Imagine being able to peek inside a black hole and even perform experiments there. It may not be as far-fetched as it sounds, thanks to a team which claims to have simulated a black hole’s event horizon in the lab. -- Ulf Leonhardt at the University of St Andrews, UK, and his colleagues accomplished the feat by firing lasers down an optical fiber, exploiting the fact that different wavelengths of light move at different speeds within an optical fiber.

They first shot a relatively slowmoving laser pulse through the fibre, and then sent a faster “probe wave” chasing after it. The first pulse distorts the optical properties of the fibre simply by travelling through it. This distortion forces the speedy probe wave to slow down dramatically when it catches up with the slower pulse and tries to move through it. In fact, the probe wave becomes trapped and can never overtake the pulse’s leading edge, which effectively becomes a black hole event horizon, beyond which light cannot escape.

This “laser black hole” could allow physicists to examine what happens to light on both sides of a event horizon – “a feat that is utterly impossible in astrophysics”, the authors note in their paper. ...   more »

As a theoretical physicist, Janna Levin probes whether the universe is finite or infinite. As a novelist, she explored the separate but parallel lives of two influential 20th-century scientists: Kurt Gödel and Alan Turing. Their work laid the foundations for computer intelligence while challenging fundamental notions about how we can know what is true. ...   more »

This recent report, from the session on 'Tipping Points' at the important Dec.07 American Geophysical Union meeting in San Francisco, illustrates the complexity of current technical discussions about the validity of the increasingly disruptive climate change scenarios being projected by various Climate Change computer models. The bottom line is that our models may be seriously underestimating the rapidly of the coming changes, as indicated in the previously posted article re the melting of arctic sea ice. ~rj

...In Hansen's talk, he did try to clarify what he meant by a tipping point. His notion of this has less to do with what mathematicians understand as "bifurcations," and more to do with a kind of inertia in the climate system. He means things like having passed a threshold of CO2 which, given warming in the pipeline and the lifetime of CO2, commits a certain discrete event — e.g. loss of perennial sea ice or the Amazon rainforest– to occurring even if we were to later reduce emissions to zero. He tried to distinguish between reversible and irreversible tipping points...

...where things get interesting is where you try to explain a magnitude of signal this big in terms of basic physics. This is important because there is a perception that GCM's vastly underestimate the amplitude of the response to total solar luminosity, leading to a perception that there is some "missing physics" (whether it be exotic amplification of a stratospheric response, or something like clouds and cosmic rays)...

But — the take-home point is that at this point the study of solar cycle response very strongly supports the notion that there is no need to invoke any mysterious or exotic missing physics (like cosmic ray modulation of clouds) in order to represent the response of climate to solar variability. If some models underestimate the response, this is likely to have more to do with errors in the vertical mixing of heat than any missing fundamental physics. ...   more »

Scientists in the US have presented one of the most dramatic forecasts yet for the disappearance of Arctic sea ice. -- Their latest modelling studies indicate northern polar waters could be ice-free in summers within just 5-6 years.

Professor Wieslaw Maslowski told an American Geophysical Union meeting that previous projections had underestimated the processes now driving ice loss.

Summer melting this year reduced the ice cover to 4.13 million sq km, the smallest ever extent in modern times. -- Remarkably, this stunning low point was not even incorporated into the model runs of Professor Maslowski and his team, which used data sets from 1979 to 2004 to constrain their future projections.

"Our projection of 2013 for the removal of ice in summer is not accounting for the last two minima, in 2005 and 2007," the researcher from the Naval Postgraduate School, Monterey, California, explained to the BBC. -- "So given that fact, you can argue that may be our projection of 2013 is already too conservative." ...   more »

Here's another excerpt from Michael Talbot's fascinating book The Holographic Universe. I continue to recommend this book.

...Other experiences included the accessing of racial and collective memories. Individuals of Slavic origin experienced what it was like to participate in the conquests of Genghis Khan's Mongolian hordes, to dance in trance with the Kalahari bushmen, to undergo the initiation rites of the Australian aborigines, and to die as sacrificial victims of the Aztecs. And again the descriptions frequently contained obscure historical facts and a degree of knowledge that was often completely at odds with the patient's education, race, and previous exposure to the subject. For instance, one uneducated patient gave a richly detailed account of the techniques involved in the Egyptian practice of embalming and mummification, including the form and meaning of various amulets and sepulchral boxes, a list of the materials used in the fixing of the mummy cloth, the size and shape of the mummy bandages, and other esoteric facets of Egyptian funeral services. Other individuals tuned into the cultures of the Far East and not only gave impressive descriptions of what it was like to have a Japanese, Chinese, or Tibetan psyche, but also related various Taoist or Buddhist teachings.

In fact, there did not seem to be any limit to what Grof's LSD subjects could tap into. They seemed capable of knowing what it was like to be every animal, and even plant, on the tree of evolution. They could experience what it was like to be a blood cell, an atom, a thermonuclear process inside the sun, the consciousness of the entire planet, and even the consciousness of the entire cosmos. More than that, they displayed the ability to transcend space and time, and occasionally they related uncannily accurate precognitive information. In an even stranger vein they sometimes encountered nonhuman intelligences during their cerebral travels, discarnate beings, spirit guides from "higher planes of consciousness," and other suprahuman entities...

Perhaps Grof's most remarkable discovery is that the same phenomena reported by individuals who have taken LSD can also be experienced without resorting to drugs of any kind...The Grofs call their technique holotropic therapy and use only rapid and controlled breathing, evocative music, and massage and body work, to induce altered states of consciousness. To date, thousands of individuals have attended their workshops and report experiences that are every bit as spectacular and emotionally profound as those described by subjects of Grof's previous work on LSD...   more »

Entheogen: Awakening the Divine Within is a feature length documentary which invites the viewer to rediscover an enchanted cosmos in the modern world by awakening to the divine within. The film examines the re-emergence of archaic techniques of ecstasy in the modern world by weaving a synthesis of ecological and evolutionary awareness, electronic dance culture, and the current pharmacological re-evaluation of entheogenic compounds.

Within a narrative framework that imagines consciousness itself to be evolving, Entheogen documents the emergence of techno-shamanism in the post-modern world that frames the following questions: How can a renewal of ancient initiatory rites of passage alleviate our ecological crisis? What do trance dancing and festivals celebrating unbridled artistic expression speak to in our collective psyche? How do we re-invent ourselves in a disenchanted world from which God has long ago withdrawn? Entheogen invites the viewer to consider that the answers to these questions lie within the consciousness of each and every human being, and are accessible if only we give ourselves permission to awaken to the divine within. ...   more »
