It's Official: Tunisia Now Freer than the U.S. | Informed Comment - 0 views

  •  
    An Arab country with neither secret police nor censorship is unprecedented in recent decades. Tunisia is inspiring similar demands in Egypt and Jordan. When skeptics wonder if the Revolutions of 2011 would really change anything essential in the region, they would be wise to keep an eye on these two developments in Tunisia, which, if consolidated, would represent an epochal transformation of culture and politics. Arguably, Tunisians are now freer than Americans. The US government thinks our private emails are actually public. The FBI and NSA routinely read our email and they and other branches of the US government issue security letters in the place of warrants allowing them to tap phones and monitor whom we call, and even to call up our library records and conduct searches of our homes without telling us about it. Millions of telephone records were turned over to George W. Bush by our weaselly telecom companies. Courts allow government agents to sneak onto our property and put GPS tracking devices under our automobiles without so much as a warrant or even probable cause. Mr. Obama thinks this way of proceeding is a dandy idea.

Rationally Speaking: The very foundations of science - 0 views

  • The first way to think about probability is as a measure of the frequency of an event: if I say that the probability of a coin to land heads up is 50% I may mean that, if I flip the coin say 100 times, on average I will get heads 50 times. This is not going to get us out of Hume’s problem, because probabilities interpreted as frequencies of events are, again, a form of induction
  • Secondly, we can think of probabilities as reflecting subjective judgment. If I say that it is probable that the coin will land heads up, I might simply be trying to express my feeling that this will be the case. You might have a different feeling, and respond that you don’t think it's probable that the coin will lend heads up. This is certainly not a viable solution to the problem of induction, because subjective probabilities are, well, subjective, and hence reflect opinions, not degrees of truth.
  • Lastly, one can adopt what Okasha calls the logical interpretation of probabilities, according to which there is a probability X that an event will occur means that we have objective reasons to believe (or not) that X will occur (for instance, because we understand the physics of the solar system, the mechanics of cars, or the physics of coin flipping). This doesn’t mean that we will always be correct, but it does offer a promising way out of Hume’s dilemma, since it seems to ground our judgments on a more solid foundation. Indeed, this is the option adopted by many philosophers, and would be the one probably preferred by scientists, if they ever gave this sort of thing a moment’s thought.

The Technium: The World Without Technology - 0 views

  • Although strictly speaking simple tools are a type of technology made by one person, we tend to think of technology as something much more complicated. But in fact technology is anything designed by a mind. Technology includes not only nuclear reactors and genetically modified crops, but also bows and arrows, hide tanning techniques, fire starters, and domesticated crops. Technology also includes intangible inventions such as calendars, mathematics, software, law, and writing, as these too derive from our heads. But technology also must include birds' nests and beaver dams since these too are the work of brains. All technology, both the chimp's termite fishing spear and the human's fishing spear, the beaver's dam and the human's dam, the warbler's hanging basket and the human's hanging basket, the leafcutter ant's garden and the human's garden, are all fundamentally natural. We tend to isolate human-made technology from nature, even to the point of thinking of it as anti-nature, only because it has grown to rival the impact and power of its home. But in its origins and fundamentals a tool is as natural as our life.
  • The gravity of technology holds us where we are. We accept our attachment. But to really appreciate the effects of technology – both its virtues and costs -- we need to examine the world of humans before technology. What were our lives like without inventions? For that we need to peek back into the Paleolithic era when technology was scarce and humans lived primarily surrounded by things they did not make. We can also examine the remaining contemporary hunter-gatherer tribes still living close to nature to measure what, if anything, they gain from the small amount of technology they use.
  • Then about 50,000 years ago something amazing happened. While the bodies of early humans in Africa remained unchanged, their genes and minds shifted noticeably. For the first time hominins were full of ideas and innovation. These newly vitalized modern humans, which we now call Sapiens, charged into new regions beyond their ancestral homes in eastern Africa. They fanned out from the grasslands and in a relatively brief burst exploded from a few tens of thousands in Africa to an estimated 8 million worldwide just before the dawn of agriculture 10,000 years ago.

  • It should have been clear to Neanderthal, as it is now clear to us in the 21st century, that something new and big had appeared -- a new biological and geological force. A number of scientists (Richard Klein, Ian Tattersall, William Calvin, among many others) think that the "something" that happened 50,000 years ago was the invention of language. Up until this point, humanoids were smart. They could make crude tools in a hit or miss way and handle fire – perhaps like an exceedingly smart chimp. The African hominin's growing brain size and physical stature had leveled off its increase, but evolution continued inside the brain.  "What happened 50,000 years ago," says Klein, "was a change in the operating system of humans. Perhaps a point mutation effected the way the brain is wired that allowed languages, as we understand language today: rapidly produced, articulate speech."  Instead of acquiring a larger brain, as the Neanderthal and Erectus did, Sapien gained a rewired brain.  Language altered the Neanderthal-type mind, and allowed Sapien minds for the first time to invent with purpose and deliberation. Philosopher Daniel Dennet crows in elegant language: "There is no step more uplifting, more momentous in the history of mind design, than the invention of language. When Homo sapiens became the beneficiary of this invention, the species stepped into a slingshot that has launched it far beyond all other earthly species." The creation of language was the first singularity for humans. It changed everything. Life after language was unimaginable to those on the far side before it.

Tiny LEDs Pump out Quantum-Entangled Photons | 80beats | Discover Magazine - 0 views

  •  
    LEDsThe strange quantum state of entanglement isn't just challenging to think about, it's hard to create. This "spooky" phenomenon-in which two particles are linked, even if they're separated by distance-can be created by scientists in the lab using bulky lasers. But scientists published a study in Nature today in which they created a light-emitting diode (LED) that produces entangled photons.

An illustrated guide to the latest climate science « Climate Progress - 0 views

  •  
    "In 2009, the scientific literature caught up with what top climate scientists have been saying privately for a few years now: * Many of the predicted impacts of human-caused climate change are occurring much faster than anybody expected - particularly ice melt, everywhere you look on the planet. * If we stay anywhere near our current emissions path, we are facing incalculable catastrophes by century's end, including rapid sea level rise, massive wildfires, widespread Dust-Bowlification, large oceanic dead zones, and 9°F warming - much of which could be all but irreversible for centuries. And that's not the worst-case scenario! * The consequences for human health and well being would be extreme. That's no surprise to anybody who has talked to leading climate scientists in recent years, read my book Hell and High Water (or a number of other books), or followed this blog. Still, it is a scientific reality that I don't think more than 2 people in 100 fully grasp, so I'm going to review here the past year in climate science. I'll focus primarily on the peer-reviewed literature, but also look at some major summary reports."

    In a world of rapidly accelerating change, from iPads to eBooks to genetic mapping to MagLev trains, we can't help but wonder if technology is our servant or our master, and whether it is taking us in a healthy direction as a society.* What forces drive the steady march of innovation?* How can we build environments in our schools, our businesses, and in our private lives that encourage the creation of new ideas--ideas that build on the new technology platforms in socially responsible ways?Kevin Kelly and Steven Johnson look at where technology is taking us. One of the co-founders of Wired Magazine, Kelly's new book, What Technology Wants, makes the argument that technology as a whole is not a jumble of wires and metal but a living, evolving organism that has its own unconscious needs and tendencies. Johnson's new book, Where Good Ideas Come From, explains why certain spaces, from 18th-century coffeehouses to the World Wide Web, have an uncanny talent for encouraging innovative thinking.

Mind-reading scan identifies simple thoughts - health - 26 May 2011 - New Scientist - 0 views

  •  
    A new new brain imaging system that can identify a subject's simple thoughts may lead to clearer diagnoses for Alzheimer's disease or schizophrenia - as well as possibly paving the way for reading people's minds. Michael Greicius at Stanford University in California and colleagues used functional magnetic resonance imaging (fMRI) to identify patterns of brain activity associated with different mental states. He asked 14 volunteers to do one of four tasks: sing songs silently to themselves; recall the events of the day; count backwards in threes; or simply relax. Participants were given a 10-minute period during which they had to do this. For the rest of that time they were free to think about whatever they liked. The participants' brains were scanned for the entire 10 minutes, and the patterns of connectivity associated with each task were teased out by computer algorithms that compared scans from several volunteers doing the same task. This differs from previous experiments, in which the subjects were required to perform mental activities at specific times and the scans were then compared with brain activity when they were at rest. Greicius reasons his method encourages "natural" brain activity more like that which occurs in normal thought.

Citizen Scientist 2.0 - 1 views

  •  
    What does the future of science look like? About a year ago, I was asked this question. My response then was: Transdisciplinary collaboration. Researchers from a variety of domains-biology, philosophy, psychology, neuroscience, economics, law-all coming together, using inputs from each specialized area to generate the best comprehensive solutions to society's more persistent problems. Indeed, it appears as if I was on the right track, as more and more academic research departments, as well as industries, are seeing the value in this type of partnership. Now let's take this a step further. Not only do I think we will be relying on inputs from researchers and experts from multiple domains to solve scientific problems, but I see society itself getting involved on a much more significant level as well. And I don't just mean science awareness. I'm talking about actually participating in the research itself. Essentially, I see a huge boom in the future for Citizen Science.

    October 24, 2008 - Google Tech Talks June 16, 2008 ABSTRACT Explore the brain's amazing ability to change throughout a person's life. This phenomenon-called neuroplasticty-is the science behind brain fitness, and it has been called one of the most extraordinary scientific discoveries of the 20th century. PBS had recently aired this special, The Brain Fitness Program, which explains the brain's complexities in a way that both scientists and people with no scientific background can appreciate. This is opportunity to learn more about how our minds work-and to find out more about the latest in cutting-edge brain research, from the founder of Posit Science and creator of the Brain Fitness Program software, Dr. Michael Merzenich. Speaker: Dr. Michael Merzenich, Ph.D. Michael M. Merzenich, PhD: Chief Scientific Officer Dr. Merzenich leads the company's scientific team. For more than three decades, Dr. Merzenich has been a leading pioneer in brain plasticity research. He is the Francis A. Sooy Professor at the Keck Center for Integrative Neurosciences at UCSF. Dr. Merzenich is a member of the National Academy of Sciences. He is the recipient of numerous awards and prizes, including the Ipsen Prize, Zulch Prize of the Max Planck Institute, Thomas Alva Edison Patent Award and Purkinje Medal. Dr. Merzenich has published more than 200 articles, including many in leading peer-reviewed journals, such as Science and Nature. His work is also often covered in the popular press, including the New York Times, the Wall Street Journal, Time and Newsweek. He has appeared on Sixty Minutes II, CBS Evening News and Good Morning America. In the late 1980s, Dr. Merzenich was on the team that invented the cochlear implant, now distributed by market leader Advanced Bionics. In 1996, Dr. Merzenich was the founding CEO of Scientific Learning Corporation (Nasdaq: SCIL), which markets and distributes software that applies principles of brain plasticity to assist children with language
