Lesson 12.2 Enrichment: Scarcity and Government Intervention in Colonial Massachusetts Serious European settlement of Cape Cod in Massachusetts, USA began with the arrival of the Pilgrims in 1620. The land was almost totally tree-covered, but logging for fuel and building material, and to clear fields for cultivation, quickly became widespread. Wood was burned in great amounts to boil sea water to obtain salt for packing cod for shipping, and to 'try' whale meat to extract the valuable oil. In Eastham, the freedom-loving pioneers banned cutting of wood on the common lands in 1690 except to supply wood for sales out of town. Symbiosis In a symbiotic mutualistic relationship, the clownfish feeds on small invertebrates that otherwise have potential to harm the sea anemone, and the fecal matter from the clownfish provides nutrients to the sea anemone. The clownfish is additionally protected from predators by the anemone's stinging cells, to which the clownfish is immune. Symbiosis (from Ancient Greek σύν "together" and βίωσις "living") is close and often long-term interaction between two or more different biological species. In 1877, Albert Bernhard Frank used the word symbiosis (which previously had been used to depict people living together in community) to describe the mutualistic relationship in lichens. In 1879, the German mycologist Heinrich Anton de Bary defined it as "the living together of unlike organisms." Some symbiotic relationships are obligate, meaning that both symbionts entirely depend on each other for survival. Physical interaction Alder tree root nodule Mutualism Parasitism

Marxists Internet Archive Wrinkled doughnut solves geometrical mystery - physics-math - 30 April 2012 This may be the weirdest doughnut you have ever seen, but it solves a long-standing geometrical puzzle that evaded mathematicians including Nobel laureate John Nash, who inspired the film A Beautiful Mind. Topology is the branch of mathematics concerned with the geometric deformations of objects. According to its rules, a certain type of flat square - in which opposite edges have been mathematically linked - is equivalent to a holed-doughnut, or torus, because one can easily be turned into the other. First, form a cylinder by joining the top edge of the square to the bottom edge, then bend that cylinder into a circle and join its two open ends. There is just one problem: for the two ends to meet, the torus must be stretched in a way that distorts the original shape of the square. Any horizontal lines on the original square will be stretched on the torus, while vertical lines will remain the same. Molecular doughnut 3D printout The method of wrinkling is known as convex integration theory.

Florida’s flawed “voter-cleansing” program If Vice President Al Gore is wondering where his Florida votes went, rather than sift through a pile of chad, he might want to look at a “scrub list” of 173,000 names targeted to be knocked off the Florida voter registry by a division of the office of Florida Secretary of State Katherine Harris. A close examination suggests thousands of voters may have lost their right to vote based on a flaw-ridden list that included purported “felons” provided by a private firm with tight Republican ties. Early in the year, the company, ChoicePoint, gave Florida officials a list with the names of 8,000 ex-felons to “scrub” from their list of voters. But it turns out none on the list were guilty of felonies, only misdemeanors. The company acknowledged the error, and blamed it on the original source of the list — the state of Texas. Florida officials moved to put those falsely accused by Texas back on voter rolls before the election. “I was very upset,” Howell said. This story has been corrected.
Taureau (symbolisme). Figure essentielle de l'art paléolithique, le taureau jouait également un rôle central dans les plus anciennes religions connues de la Méditerranée et de son pourtour (mont Bégo, Crète , Anatolie , etc). Taureaux paléolithiques représentés sur les parois de la grotte de Lascaux. Les Égyptiens révéraient le taureau ou boeuf sacré, sous le nom d'Apis. , signe équinoxial , alors premier des douze signes du zodiaque, qu'Osiris, c'est-à-dire ici le Soleil, avait rendu dépositaire de la fécondité. Ainsi que dans beaucoup de religions asiatiques, le taureau avait été adopté, dès les premiers âges, par les Égéens, comme le symbole de la force et de l'énergie créatrice. Tête de taureau symbolisant le dieu Taureau (Cnossos, Crète). Le dieu Taureau n'était d'ailleurs pas l'unique aspect sous lequel se présentait le dieu crétois. Chez les anciens Grecs et Romains, le taureau était la victime la plus ordinaire des sacrifices. Le taureau qu'on sacrifiait à Apollon avait ordinairement les cornes dorées. .
Lesson 12.7 Enrichment: Estimates Dr. Alley summarized many estimates of the costs of dealing with climate change in his book Earth: The Operators' Manual. Some of those are repeated here. The Intergovernmental Panel on Climate Change (IPCC) from 2007 found costs of between slight growth (0.6%) and somewhat larger magnitude shrinkage (3.0%) of global GDP in 2030, versus business-as-usual, for different paths toward stabilizing the atmospheric concentration of CO2 at between 1.6 and 2.5 times the level before the industrial revolution. (IPCC, 2007, Summary for Policymakers, in Metz, B., O. Much relevant work has been done in Germany. (German Advisory Council on Global Change (WBGU) (Grassl, H., J. Comparable estimates - average about 1% cost, as low as 1% benefit and as high as 4% costs - were summarized in Hasselmann, K., 2009, 'What to do?
