    Have you played with Google Labs' NGram Viewer? It's an addicting tool that lets you search for words and ideas in a database of 5 million books from across centuries. Erez Lieberman Aiden and Jean-Baptiste Michel show us how it works, and a few of the surprising things we can learn from 500 billion words.

  • 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.

    The SAO/NASA Astrophysics Data System (ADS) is a Digital Library portal for researchers in Astronomy and Physics, operated by the Smithsonian Astrophysical Observatory (SAO) under a NASA grant. The ADS maintains three bibliographic databases containing more than 6.9 million records: Astronomy and Astrophysics, Physics, and arXiv e-prints. The main body of data in the ADS consists of bibliographic records, which are searchable through highly customizable query forms, and full-text scans of much of the astronomical literature which can be browsed or searched via our full-text search interface. Integrated in its databases, the ADS provides access and pointers to a wealth of external resources, including electronic articles, data catalogs and archives. We currently have links to over 7.6 million records maintained by our collaborators.

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

    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.

  • 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.
