The American Conservative » Return of the War Party - 0 views

  •  
    Before we let ourselves be stampeded into another unnecessary war, let us review a few facts that seem to contradict the war propaganda. First, last week's acknowledgment that Iran has enough enriched uranium for one atom bomb does not mean Iran is building an atom bomb. To construct a nuclear device, the ton of low-enriched uranium at Natanz would have to be run through a second cascade of high-speed centrifuges to produce 55 pounds of highly enriched uranium (HUE). There is no evidence Iran has either created the cascade of high-speed centrifuges necessary to produce HUE or that Iran has diverted any of the low-enriched uranium from Natanz. And the International Atomic Energy Agency inspectors retain full access to Natanz. And rather than accelerating production of low-enriched uranium, only 4,000 of the Natanz centrifuges are operating. Some 1,000 are idle. Why? Dr. Mohamed El-Baradei, head of the IAEA, believes this is a signal that Tehran wishes to negotiate with the United States, but without yielding any of its rights to enrich uranium and operate nuclear power plants.

Curriki - TerrariumsandVivariums - 1 views

  •  
    In this comprehensive five to ten week unit, late elementary students (grades 5-6) will plan, create and observe three different environments: woodland, desert, and tropical. Each environment provides opportunity for activities studying adaptations of plants and animals, with focused activities on the earthworm and isopod. Humane treatment of organisms is stressed. This resource includes correlations with NY state standards. Each "kit" in the Curriki repository includes a teacher's manual and student activity book. The teacher's manual includes a unit overview, scheduling information, extensive and clear background information materials, preparation instructions, discussion questions, an assessment, cross-curricular extension ideas, a glossary and teacher references. Each student manual includes clear, reproducible student handouts and a glossary. The last section in the "kit" is a wiki, and Curriki members are encouraged to edit and build up the existing curriculum. It may take some time initially to organize and order all the necessary supplies, but these written materials are excellent and can be used immediately in the classroom.

Göbekli Tepe - Pictures, More From National Geographic Magazine - 67 views

  • The Birth of ReligionWe used to think agriculture gave rise to cities and later to writing, art, and religion. Now the world’s oldest temple suggests the urge to worship sparked civilization.
  • Before them are dozens of massive stone pillars arranged into a set of rings, one mashed up against the next. Known as Göbekli Tepe (pronounced Guh-behk-LEE TEH-peh), the site is vaguely reminiscent of Stonehenge, except that Göbekli Tepe was built much earlier and is made not from roughly hewn blocks but from cleanly carved limestone pillars splashed with bas-reliefs of animals—a cavalcade of gazelles, snakes, foxes, scorpions, and ferocious wild boars. The assemblage was built some 11,600 years ago, seven millennia before the Great Pyramid of Giza. It contains the oldest known temple. Indeed, Göbekli Tepe is the oldest known example of monumental architecture—the first structure human beings put together that was bigger and more complicated than a hut. When these pillars were erected, so far as we know, nothing of comparable scale existed in the world.
  • At the time of Göbekli Tepe's construction much of the human race lived in small nomadic bands that survived by foraging for plants and hunting wild animals. Construction of the site would have required more people coming together in one place than had likely occurred before. Amazingly, the temple's builders were able to cut, shape, and transport 16-ton stones hundreds of feet despite having no wheels or beasts of burden. The pilgrims who came to Göbekli Tepe lived in a world without writing, metal, or pottery; to those approaching the temple from below, its pillars must have loomed overhead like rigid giants, the animals on the stones shivering in the firelight—emissaries from a spiritual world that the human mind may have only begun to envision.

  • Archaeologists are still excavating Göbekli Tepe and debating its meaning. What they do know is that the site is the most significant in a volley of unexpected findings that have overturned earlier ideas about our species' deep past. Just 20 years ago most researchers believed they knew the time, place, and rough sequence of the Neolithic Revolution—the critical transition that resulted in the birth of agriculture, taking Homo sapiens from scattered groups of hunter-gatherers to farming villages and from there to technologically sophisticated societies with great temples and towers and kings and priests who directed the labor of their subjects and recorded their feats in written form. But in recent years multiple new discoveries, Göbekli Tepe preeminent among them, have begun forcing archaeologists to reconsider. At first the Neolithic Revolution was viewed as a single event—a sudden flash of genius—that occurred in a single location, Mesopotamia, between the Tigris and Euphrates Rivers in what is now southern Iraq, then spread to India, Europe, and beyond. Most archaeologists believed this sudden blossoming of civilization was driven largely by environmental changes: a gradual warming as the Ice Age ended that allowed some people to begin cultivating plants and herding animals in abundance. The new research suggests that the "revolution" was actually carried out by many hands across a huge area and over thousands of years. And it may have been driven not by the environment but by something else entirely.
  • Most of the world's great religious centers, past and present, have been destinations for pilgrimages
  • Göbekli Tepe may be the first of all of them, the beginning of a pattern. What it suggests, at least to the archaeologists working there, is that the human sense of the sacred—and the human love of a good spectacle—may have given rise to civilization itself.
  • n the 1960s archaeologists from the University of Chicago had surveyed the region and concluded that Göbekli Tepe was of little interest. Disturbance was evident at the top of the hill, but they attributed it to the activities of a Byzantine-era military outpo
  • To Schmidt, the T-shaped pillars are stylized human beings, an idea bolstered by the carved arms that angle from the "shoulders" of some pillars, hands reaching toward their loincloth-draped bellies. The stones face the center of the circle—as at "a meeting or dance," Schmidt says—a representation, perhaps, of a religious ritual. As for the prancing, leaping animals on the figures, he noted that they are mostly deadly creatures: stinging scorpions, charging boars, ferocious lions. The figures represented by the pillars may be guarded by them, or appeasing them, or incorporating them as totems.
  • nches below the surface the team struck an elaborately fashioned stone. Then another, and another—a ring of standing pillars.
  • Geomagnetic surveys in 2003 revealed at least 20 rings piled together, higgledy-piggledy, under the earth.
  • he pillars were big—the tallest are 18 feet in height and weigh 16 tons. Swarming over their surfaces was a menagerie of animal bas-reliefs, each in a different style, some roughly rendered, a few as refined and symbolic as Byzantine art.
  • The circles follow a common design. All are made from limestone pillars shaped like giant spikes or capital T's.
  • They hadn't yet mastered engineering." Knoll speculated that the pillars may have been propped up, perhaps by wooden posts.
  • Within minutes of getting there," Schmidt says, he realized that he was looking at a place where scores or even hundreds of people had worked in millennia past.
  • Puzzle piled upon puzzle as the excavation continued. For reasons yet unknown, the rings at Göbekli Tepe seem to have regularly lost their power, or at least their charm. Every few decades people buried the pillars and put up new stones—a second, smaller ring, inside the first.
  • he site may have been built, filled in, and built again for centuries.
  • Bewilderingly, the people at Göbekli Tepe got steadily worse at temple building.
  • Finally the effort seems to have petered out altogether by 8200 B.C. Göbekli Tepe was all fall and no rise.

Understanding the power of stories - The Learner's Way - 28 views

  •  
    We are the stories that we tell and it is the stories we share which unite us. This was the seed of an idea planted by a day with author, artist, musician and story teller Boori Pryor. Understanding the power that our stories have allows us to better value their role in our lives, to see them as more than recounts of the past or imaginings of the future. Stories should be viewed as the powerful agents that they are with the force to shape who we are as much as we shape them.

Hydrogen vehicle - Wikipedia, the free encyclopedia - 13 views

      Is hydrogen sustainable? depends on the source. see this highlight.
  • While methods of hydrogen production that do not use fossil fuel would be more sustainable
  • The challenges facing the use of hydrogen in vehicles include production, storage, transport and distribution.
  • ...3 more annotations...
  • The hydrogen infrastructure consists mainly of industrial hydrogen pipeline transport and hydrogen-equipped filling stations like those found on a hydrogen highway. Hydrogen stations which are not situated near a hydrogen pipeline can obtain supply via hydrogen tanks, compressed hydrogen tube trailers, liquid hydrogen tank trucks or dedicated onsite production.
  • Hydrogen use would require the alteration of industry and transport on a scale never seen before in history. For example, according to GM, 70% of the U.S. population lives near a hydrogen-generating facility but has little access to hydrogen, despite its wide availability for commercial use.[64] The distribution of hydrogen fuel for vehicles throughout the U.S. would require new hydrogen stations that would cost, by some estimates approximately 20 billion dollars[65] and 4.6 billion in the EU.[66] Other estimates place the cost as high as half trillion dollars in the United States alone.[67]
  • Hydrogen fuel does not occur naturally on Earth and thus is not an energy source, but is an energy carrier. Currently it is most frequently made from methane or other fossil fuels. However, it can be produced from a wide range of sources (such as wind, solar, or nuclear) that are intermittent, too diffuse or too cumbersome to directly propel vehicles. Integrated wind-to-hydrogen plants, using electrolysis of water, are exploring technologies to deliver costs low enough, and quantities great enough, to compete with traditional energy sources.[2]
