    Unification theory with no extra dimensions. The first part unifies the strong nuclear force with the gravitational force in a mathematical way; the quantum vacuum is treated as a deformable system by the strong nuclear force. The second part unifies the nuclear force with the quantum vacuum in a hypothetical structure; the quantum vacuum is treated as a supersymmetric and metastable system with properties related to the different types of particles' motion.

    A unique optical multitouch sensing technology using infrared sensors has been developed by researchers at the Interface Ecology Lab at Texas A&M University. ZeroTouch allows users to literally draw pictures in midair. It provides zero-force, zero-thickness, high-frame-rate, high-resolution, transparent multitouch sensing. ZeroTouch's new forms of free-air interaction are more precise than the Microsoft Kinect, the researchers said. ZeroTouch was demonstrated at the recent ACM Conference on Human Factors in Computing Systems in Vancouver, B.C.

    Even counting vast tracks of agriculture, the technium entails fewer than one percent of the atoms on the Earth's land surface. Yet the impact which this minute fraction of technological mass and energy has on the planet is in far disproportion to its size. Measured by impact per gram or calorie, there is nothing comparable to things we invent. Technology is the most powerful force in the world.

    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.

Researchers create self-assembling nanodevices that move and change shape on demand | KurzweilAI

    Harvard researchers have created nanodevices made of DNA that self-assemble and can be programmed to move and change shape on demand. The nanodevice structure is based on the principle of tensegrity: its strength and stability results from the way it distributes and balances the counteracting forces of tension and compression. This new technology could lead to nanoscale medical devices and drug delivery systems, such as virus mimics that introduce drugs directly into diseased cells. Or it could one day be used to reprogram human stem cells to regenerate different kinds of injured organs and tissue.

  • But the implication of electricity in the sleep deficit seems hard to argue with. Whatever it is that we wish or are made to do--pursue leisure, earn a living--there are simply far more usable hours now in which to do it
  • In the United States at midnight more than five million people are at work at full-time jobs. Supermarkets, gas stations, copy shops--many of these never close.
  • Living with electric lights makes it difficult to retrieve the experience of a non-electrified society. For all but the very wealthy, who could afford exorbitant arrays of expensive artificial lights, nightfall brought the works of daytime to a definitive end. Activities that need good light--where sharp tools are wielded or sharply defined boundaries maintained; purposeful activities designed to achieve specific goals; in short, that which we call work--all this subsided in the dim light of evening. Absent the press of work, people typically took themselves safely to home and were left with time in the evening for less urgent and more sensual matters: storytelling, sex, prayer, sleep, dreaming.

  • John Staudenmaier, a historian of technology and a Jesuit priest, for a recent conference at MIT. (The essay will appear in a book called The Idea of Progress Revisited, edited by Leo Marx and Bruce Mazlish.) Staudenmaier makes the point--obvious when brought up, though we've mostly lost sight of it--that from the time of the hominid Lucy, in Hadar, Ethiopia, to the time of Thomas Edison, in West Orange, New Jersey, the onset of darkness sharply curtailed most kinds of activity for most of our ancestors.

    Speculative connections between electric lighting, sleep deficits, and health.

    I wonder if the driving force behind the sleep deficit is in fact more pervasive, and indeed global in nature: the triumph of light.

    64% of college students in a global survey said that if forced to choose, they would opt for having an internet connection rather than a car. 40% said the internet is more important to them than dating, going out with friends, or listening to music. The Cisco Connected World Technology Report draws on surveys of some 1,400 students in 14 countries.Source: Is the Internet a Fundamental Human Necessity?

    Today's world is witnessing a growing trend toward digitization, connectivity, and automation. However, the driving force behind this transformation, which is often overlooked, is embedded systems technology. Embedded systems are crucial to modern life and play a significant role in various aspects. As science and technology continue to advance, the potential applications of embedded systems are expanding rapidly. Embedded software is widely used in various fields, such as defense instruments, railroad networks, telecommunications, electronic payments, consumer electronics, and more. The usage of electronic devices is also quickly increasing in the present day.

  • 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.
