Hey, kids. A few days ago, I saw a TV commercial about a “Back to School” sale. Uh-oh, it’s that time of the year again, I thought. It’s time for students to start planning for the next academic year. And I don’t mean what clothes, shoes, and accessories you’re planning on wearing. Remember all the vocabulary you learnt in your foreign-language class? How about those pesky grammar rules? If you answered “yes,” congratulations! If you answered, “no,” you need to get to work; but don’t worry: there are plenty of Amsco books to help you review and get ready for this year’s challenges. Amsco foreign-languages workbooks aim to provide students with a concise and systematic review of the essential elements of the target language. Abundant and varied communicative exercises help students master each grammar topic. These workbooks are designed so that each chapter is complete in itself. The chapters may be used in any order, according to the student’s individual needs. Explanations are clear and concise, and are followed by numerous examples. There is a great variety of exercises that provide both communicative and written practice. Check out some our offerings: Spanish First Year Spanish Two Years Spanish Three Years Spanish Four Years French First Year French Two Years French Three Years French Four Years Italian First Italian Two And Three Years And there are many more.

You may be asking: What has La Nada to do with me? Well, remember all those snow storms and cold weather last January and February? They may have been caused by La Nada. According to NASA climatologist Bill Patzert, “La Niña was strong in December, but back in January it pulled a disappearing act and left us with nothing—La Nada—to constrain the jet stream. Like an unruly teenager, the jet stream took advantage of the newfound freedom—and the results were disastrous.” The jet stream meandered wildly around the United States and the weather pattern became dominated by strong outbreaks of frigid polar air, producing blizzards across the West, Upper Midwest, and Northeast in the United States.
In the spring, there were many strong thunderstorms and tornados. Russell Schneider, Director of the NOAA-NWS Storm Prediction Center, explains: “First, very strong winds out of the south carrying warm, moist air from the Gulf of Mexico met cold jet stream winds racing in from the west. Stacking these two air masses on top of each other created the degree of instability that fuels intense thunderstorms.”
According to Patzert, “The jet stream—on steroids—acted as an atmospheric mix master, causing tornadoes to explode across Dixie and Tornado Alleys, and even into Massachusetts.”
The next time someone asks you: What’s up with the weather? You can say: “It’s nothing,” and smile sweetly.

Danger! |
First, the bad plant news. I recently wrote a blog about an invasive fish species. There are many invasive animal species–both on land and in the water–that wreak havoc on native ecosystems. There are invasive plant species as well. Conservationists are already familiar with invasive plant species that can clog waterways or take over landscapes. But people usually do not think of invasive plants as personally threatening in the way that invasive animals can be. Think of the pythons that are now spreading through Florida. Now, however, there is an invasive giant weed that poses a threat to humans and it sounds like something from an Aliens movie. Called the Giant Hogweed, this plant is originally from the Caucasus region of Eurasia. In the 1900s, it was introduced to Europe, Britain, and North America as an ornamental species; it grows to over 15 feet in height and sprouts clusters of attractive white flowers. Now this plant is officially listed as a noxious weed; people are warned not to touch it because of the risk of skin irritation. It turns out that the sap of the Giant Hogweed can cause blisters and scarring in humans, and can even result in blindness if it comes into contact with the eyes. Giant Hogweed is called a phototoxic plant because its sap causes severe inflammations when the skin is exposed to sunlight. Blisters develop within 48 hours and form scars that can last several years. The plant should be removed by personnel from government environmental agencies, since cutting or mowing it can expose one to the dangerous sap. Be on the lookout for this giant plant and do not be tempted to touch it!

Was the response satisfactory? The Board's memo cites “variations in the use of [inverse] notation throughout New York State,” which seems to evade blame for a lousy question. A prominent math teacher blogger responded on his blog, “How could the test-makers not be aware of ‘variations in notation’? Also, notice how there is an asymmetric justification burden on a kid claiming (correctly) that the inverse does not exist.” A lousy question shakes the faith that teachers and students have in the standardized test as a valid assessment of student understanding. For instance, the same blogger concluded, “I have no confidence in New York State’s ability to create a good test of mathematics, at any level.”
It is my sincere hope that this controversy and the appearance of a misleading question will lead to both (a) more opportunities to explore the meaning of invertible functions and one-to-one functions, demanding students to be more savvy test-takers; and (b) increased scrutiny and more careful construction of New York’s Regents exams. In short, as educators, better instruction and better assessment should be our smart answer to this, or any, stupid question.

Summer is a great time to relax, party, and catch up with friends and relatives. But it is also the season when thousands of students immerse themselves in a foreign culture and language by studying abroad. Summer study-abroad programs have been around for as long as I can remember. They are ideal for people with a rigorous schedule or for those who simply wish to spend their summer abroad experiencing new worlds. Summer programs can be taken for credit and as part of a curriculum, or as an extra activity that will expand one’s perspective for future studies and work. Here are a few examples of places where you can study abroad during the summer:

The study of ancient history often reveals some fascinating anecdotes, mysterious happenings, and colorful characters. Some of these are not generally known. Amsco’s Lingua Latina, Books I and II, by Professor John Traupman of St. Joseph’s University, deal with the Latin language and Roman history and culture. In Book I, Dr. Traupman describes a Roman of dubious character who was murdered in 52 B.C. Publius Claudius Pulcher (the Handsome) belonged to one of the most aristocratic families of the Roman Republic, the Claudii. One of his ancestors had built Rome’s first highway, the Via Appia, in 312 B.C. Nevertheless, he changed his name to Clodius in order to get political support from the common people, or plebians. Clodius became a notorious gang leader. He and his followers terrorized the streets of Rome. (The Roman world, at that time, was ruled by the First Triumvirate of Julius Caesar, Pompey the Great, and Marcus Crassus. These three men brought stability and order to Rome and its provinces. However, they were intense rivals. Each sought an opportunity to eliminate the other two. The death of Crassus in battle against the Parthians ultimately led to civil war between Pompey and Caesar. Pompey lost his head and Caesar emerged as sole ruler of the Roman world.) Clodius’ sister Clodia was called pulchra because of her great beauty. Like her brother, she lived a wild life, taking many lovers. Among them was the poet Catullus. Brother and sister were admired by some and feared by others. They were involved with the leading political figures of the late Republic. Among Clodius’ many criminal activities was the affair of the mysteries of the Bona Dea in December 62 B.C. These mysteries were open only to women. Dressed as a woman, Clodius entered the house of Julius Caesar while the mysteries of the goddess were being celebrated. Upon discovery, a scandal erupted. Clodius was accused of attempting to carry on an affair with Pompeia, Casesar’s wife. Whether this was true or not, Caesar divorced Pompeia. Clodius was brought to trial, but avoided conviction by bribing the jury. After the departure of Caesar for Gaul, Clodius and his gang became masters of Rome. Milo, a rival gang leader and politician, was a candidate for the consulship (Rome’s highest office) in 53 B.C. Clodius’ opposition led to street battles between armed bands of the two leaders. Milo’s gang was strong enough to hold Clodius in check. On

Happy Tau Day, the most exciting math holiday you’ve yet to discover! Today, June 28th is 6/28, which contains in order the first three digits of tau (τ), the rival of math’s most popular irrational number, pi (π).
In 2001, Bob Palais wrote an article for The Mathematical Investigator called ,“π is wrong!” In it, he insists that the choice of using π in our mathematical formulas for hundreds of years is no good. He argues that the use of τ would simplify many formulas and its derivation is much more intuitive. (Notice that the symbol resembles that for pi, but with one "leg" instead of two.)
The significance of our beloved irrational number π is that it is equal to the ratio of the circumference of any circle to its diameter--in notation, π = C/d. However, the most defining characteristic of a circle is not its diameter but its radius. A circle is defined as the collection of points on a plane that are exactly the same distance, its radius, from a point, its center. Palais argues that intuition should direct us to the use of a more elegant Circle Constant, tau, where τ is the ratio of the circumference of a circle to its radius--in notation, τ = C/r.
Self-described “notorious mathematical propagandist” Michael Hartl takes the argument even further in his now-famous “The Tau Manifesto,” which he published on Tau Day of 2010, exactly one year ago. He demonstrates with many adapted formulas that the factor of 2 is unnecessary if we incorporate it into the ratio itself. For instance, the periods of basic trigonometric functions f(x) = sin(x), and f(x) = cos(x), are in both cases 2π. Why not change them to tau instead? Palais and Hartl each list numerous other examples from calculus and physics, in which the factor of 2 is rendered obsolete by replacing 2π with τ.
The really intuitive part is revealed if you think of angle measure. How things are done now with π, a half turn of the circle is π radians, and a full turn is 2π radians. Should we adopt τ instead, τ radians would be a full turn, τ/2 radians a half turn, τ/4 radians a quarter turn, and so on.
There are, of course, instances where π appears un-doubled. For instance, the formula for area of a circle: A = πr2. Hartl shows, in a mathematically sophisticated way, that the replacement of π by τ even in this instance is the more sound choice, since it is analogous to similar formulas in physics.
An article in today’s BBC News paints the issue as a violent conflict, with pi detractors up in arms over a lifetime of educational betrayal, which seems to this mathematician something of a manufactured controversy. (I can imagine you'd be upset if you are the sort of mathematician that has memorized pi to the nth digit. If you are one of these folks, here's the start for your new parlor trick: reciting tau, 6.283185307...)

Blog: Amsco Extra! (Login to Add to MyJacketFlap) JacketFlap tags: Reading, Literature, Fiction, Add a tag Till recently, I always thought of Ambrose Bierce as “that weird horror writer who disappeared into the woods without a trace.” Actually, it wasn’t the woods. It was Mexico. In 1913, Bierce wanted an eyewitness view of the Mexican revolution, so he took off with the rebel troops. He was never seen or heard from again. He was more than just a horror writer, but stories like “The Damned Thing” (1898) show he was one of the best. In “The Damned Thing,” a hunter is savagely killed and mutilated by an invisible animal. Another goodie is “A Diagnosis of Death” (1909), in which a skeptic is warned of his oncoming death by his doctor’s ghost. Bierce was also a satirist. His The Devil’s Dictionary (1906), originally called The Cynic’s Word Book, contained definitions that crossed in common usage. (E.g., he defines cynic as “a blackguard whose faulty vision sees things as they are, not as they ought to be.”) His fierce literary criticism (Oscar Wilde hated him) and scathing view of life led people to call him “Bitter Bierce.” “War,” he once said, “is God's way of teaching Americans geography.” I was impressed by all the Civil War stories he wrote. The most famous was “An Occurrence at Owl Creek Bridge” (1890), which depicts a Confederate supporter who is about to be hanged at the bridge he tried to sabotage. “Chickamauga” (1891), his most tragic war story, is from the point of view of a six-year-old boy, a Southern planter’s son. It starts out innocently enough, with the boy crudely making a wooden sword (that even his ex-soldier father doesn’t recognize!). He leaves the plantation and marches off to play “war games.” In the woods, the boy gets lost, and falls asleep on the ground from sheer exhaustion. When he wakes up, he thinks he sees animals creeping through the woods. Actually, they’re mangled Union soldiers (the Battle of Chickamauga was one of the worst Union defeats in the Civil War), crawling away on hands and knees. Their pale, blood-streaked faces amuse the naïve boy, who’s reminded of circus clowns. In one grisly part, the boy attempts to “play horsey” on one soldier’s back: The man sank upon his breast, recovered, flung the small boy fiercely to the ground as an unbroken colt might have done, then turned upon him a face that lacked a lower jaw--from the upper teeth to the throat was a great red gap fringed with hanging shreds of flesh and splinters of bone. The unnatural prominence of nose, the absence of chin, the fierce eyes, gave this man the appearance of a great bird of prey crimsoned in throat and breast by the blood of its quarry. The man rose to his knees, the child to his feet. The man shook his fist at the child; the child, terrified at last, ran to a tree near by. . . . In the distance, the sky is red. Surrounded by the wounded, crawling mob, the boy marches ahead, playing that he is their new leader (even turning to ma

Those who study modern China know that the Communist government struggles with the yearnings and demands of its 55 ethnic minorities. What immediately comes to mind are the calls from Tibetans for more autonomy, or independence itself, and the complaints of the Uyghur people concerning religious and political discrimination in Xinjiang, the the northwest part of China. The majority Han people have been moving into both Tibet and Xinjiang, thereby changing the native cultures there. In the last few months, we have been hearing complaints from the Mongolian people in China. Mongols are upset that so many Han have moved into Inner Mongolia and disrupted their pastoral way of life. The Mongols have staged protests against the environmental damage that comes with settled agriculture, the strip-mining of coal, the building of highways, the damming of rivers, and the overgrazing of land. Background. The Mongols and Han have a long history of interactions. The nomadic Mongols invaded China many times, attracted to the relative wealth of the more settled Chinese. In fact, the Mongols even ruled China from 1279 to 1368, setting up the Yuan dynasty with its capital at Tatu, which is present-day Beijing. The Yuan dynasty was known for its religious toleration, especially of Muslims, Daoists, and Buddhists. During Mongol rule, the country prospered because the Mongols encouraged foreign and domestic trade. Eventually, the Han Chinese became dissatisfied with Mongol rule and threw them out. Since then, the Han have dominated their Mongol neighbors. Now the Peoples Republic of China rules Inner Mongolia. A Recent Novel. By coincidence, this spring I read a novel about the Han and the Mongolians in Inner Mongolia. Wolf Totem by Jiang Rong tells the tale of Chen Zhen, a Chinese Han who travels there in the 1960s during the Cultural Revolution and falls in love with the traditional Mongol way of life. He and two other Han young people work and live in a community that raises cattle, sheep, and horses on the steppe. While there, Chen learns from a local wise man of Mongolian lore and spritual life and the important place that wolves play in both.

It was just one lonely firefly, signaling its presence near a bunch of parked cars. For me it was an exciting moment. I am not even sure why. I just love the sight of these glowing insects; they mean summer is here. Their renewed presence means the species has survived yet another year and still exists to tell me it is June. But they are not really flies. So what are they? Fireflies are actually winged beetles. The 2,000 species of fireflies that exist are found in temperate and tropical habitats around the world. They are also known as lightning bugs and even as glowworms (particularly in their larval phase) and they have these names because of their “conspicuous crepuscular use of bioluminescence to attract mates or prey” (per Wikipedia). In other words, they emit light at twilight to communicate with other insects. The light is produced by a chemical reaction that occurs within a special organ in their lower abdomen. Each species has its own pattern of light flashing to find mates. Most firefly species are active at night, when their flashing light can be readily spotted. Some species of fireflies are active during the day, but they tend not to be luminescent. However, all firefly larvae glow, presumably as a way to warn would-be predators of their nasty chemical taste. As adults, the light usually signals a willingness to meet and mate. At least one species uses its flashing light for a different – and deceptive – purpose. The female of this type mimics the mating flashes of other fireflies; when a hopeful male responds, he ends up being dinner, not a mate. So much for a “light” dinner! Of course, I am not the only person who loves watching these bugs. There is a magic to watching children run through a field trying to capture fireflies. Professional institutions are also dedicated to the study of fireflies. The Museum of Science in Boston teams up with university researchers to study firefly sightings each year. Volunteers around the country help them count fireflies as a way of tracking their numbers. It seems that their population has been decreasing, and this could be due to environmental influences. There is even the Kumejima Firefly Museum in Okinawa, Japan, that is dedicated to this amazing insect. The museum celebrates the fact that there are seven species of firefly thriving on Kumejima because of the island’s clean ecosystem. So, the next time you see some bug flying near you, please don’t reach out to swat it. Just keep an eye on it and you may be rewarded by the glow of a bioluminescent love signal. Carol

Social Education, the official journal of the National Council for Social Studies, recently published a lesson plan on Starbucks. The lesson plan is great, as it analyzes American culture and consumerism through an analysis of Starbucks. It also inspired me to think of an interdisciplinary project that social studies and science teachers could co-teach on Ethos water. Ethos water is owned by Starbucks and sold in their stores. Branding itself as a responsible company, Ethos claims its mission is to help bring clean drinking water to children throughout the world. A 20-ounce bottle of Ethos water costs $1.80. Out of the $1.80 paid for each bottle of Ethos water, Starbucks will donate $.05 toward their mission. According to the article in Social Education, “they are charging customers 15 to 20 percent more than other companies . . . in other words, they charge customers to feel good about themselves.” Interviewing, an important skill for budding social scientists, could be used to determine why people are buying an overpriced bottle of water. Is it because of the “clean water” mission? Is it out of convenience? Is it for another reason altogether? As an entry point into this project, science and social studies teachers can use the debate over whether or not Ethos does more harm than good. Students could research which regions of the world are in need of clean drinking water, and the political and environmental issues that create that need. Students could also investigate the environmental impact of drinking bottled water, as well as issues regarding tap water versus bottled water. For instance, if students determine that tap water is safer than bottled water, they could argue for drinking tap water and donating the saved money to help bring clean drinking water to “dehydrated communities.” Another student might research statistics on charitable donations and determine that people who are saving money by drinking tap water would just buy something else rather than donating their savings. In that case, Ethos is invaluable, as the donation is built into the purchase. Editorial writing is another skill that could be incorporated into this project. Students could write an editorial to support or discredit Ethos. Of course, these editorials could be published in a class blog instead of a traditional paper. Then students would read each other’s opinions, include relevant links, and comment on their peers’ work.

Blog: Amsco Extra! (Login to Add to MyJacketFlap) JacketFlap tags: Science, Chemistry, Periodic Table, Add a tag I wonder how many times students have been directed to complete a table for homework or on an exam. Chemists have an incomplete table that they are trying to complete: the Periodic Table of the Elements, or the Periodic Table, for short. Uranium, element number 92 is the last naturally occurring element in the Periodic Table. Elements beyond number 92, called the transuranium elements, have all been produced in laboratories. The first transuranium element, neptunium (#93) was produced in 1940 at the University of California, Berkeley, by Edwin McMillan and Phillip Abelson by exposing uranium oxide to neutrons from a cyclotron. The last one, copernicium (#112) was officially recognized in 2009. On June 6, 2011, the Joint Working Party on the Discovery of Elements of the International Union of Pure and Applied Chemistry (IUPAC) and the International Union of Pure and Applied Physics (IUPAP) announced the addition of two new elements to the Periodic Table—element 114 and element 116. For now, element 114 is called ununquadium and element 116 is called ununhexium. These names are based on their atomic numbers. By officially acknowledging the collaboration between researchers from Lawrence-Livermore National Laboratory in California and Russia’s Joint Institute for Nuclear Research in Dubna, these researchers will get to suggest names for the new elements. The names will go through a review process before being adopted and the elements will be assigned a symbol by the IUPAC Council. Scientists produced these elements by bombarding curium (#96) atoms with calcium (#20) nuclei. In a few milliseconds, element 116 decays into element 114 which lasts about half a second before decaying into copernicium (#112). In other experiments element 114 was produced by bombarding plutonium (#94) with calcium nuclei. Notice that 96 + 20 = 116 and 94 + 20 = 114. There are three more elements waiting to be recognized: 113, 115, and 118. According to IUPAC, “Review of the claims associated with elements 113, 115, and 118 are at this time not conclusive and evidences have not met the criteria for discovery.” As soon as I hear anything more, I will let you know.

Flag Day! What's that? On this day in 1777, the Second Continental Congress adopted the stars and stripes as the nation's flag. In 1916, President Wilson officially proclaimed June 14 to be Flag Day. Since then, it has been a day to commemorate the American flag. Consider it a warm up for Independence Day.
