Visualizing Whale Songs
"
Mark Fischer, an expert in marine acoustics, has come up with another way to
illustrate whale song. He uses a more obscure method, known as the wavelet transform, which represents the sound in terms of components known as wavelets: short, discrete waves that are better at capturing cetacean song."

The Nine Eyes of Google Street View
"It was tempting to see the images as a neutral and privileged representation of reality—as though the Street Views, wrenched from any social context other than geospatial contiguity, were able to perform true docu-photography, capturing fragments of reality stripped of all cultural intentions."

Alice's adventures in algebra: Wonderland solved
"Outgunned in the specialist press, Dodgson took his mathematics to his fiction. Using a technique familiar from Euclid's proofs, reductio ad absurdum, he picked apart the "semi-logic" of the new abstract mathematics, mocking its weakness by taking these premises to their logical conclusions, with mad results. The outcome is Alice's Adventures in Wonderland."

The Mandelbulb
"The original
Mandelbrot is an amazing object that has captured the public's imagination for 30 years. It's found by following a relatively simple math formula. But in the end, it's still only 2D and flat - there's no depth, shadows, perspective, or light sourcing. What we have featured in this article is a potential 3D version of the same fractal."

A (mostly) vegetarian spider:
"A small jumping spider has taken to hunting plants instead of bugs. Bagheera kiplingi dodges throngs of aggressive ants to feast on the leaf-tip morsels of acacia shrubs, making it the first mostly vegetarian spider known to science."

The Revolutionary
"Consider, then, the Fosbury Flop, an upside-down and backward leap over a high bar, an outright—an outrageous!—perversion of acceptable methods of jumping over obstacles. An absolute departure in form and technique. It was an insult to suggest, after all these aeons, that there had been a better way to get over a barrier all along. And if there were, it ought to have come from a coach, a professor of kinesiology, a biomechanic, not an Oregon teenager of middling jumping ability."

Colombia Confronts Drug Lord’s Legacy: Hippos
"In what ecologists describe as possibly the continent’s most ambitious effort to assemble a collection of species foreign to South America, Escobar imported animals like zebras, giraffes, kangaroos, rhinoceroses and, of course, hippopotamuses. Some of the animals died or were transferred to zoos around the time Mr. Escobar was killed. But the hippos largely stayed put, flourishing in the artificial lakes dug at Mr. Escobar’s behest."

The foreign exchange student
"Some years ago we had a foreign exchange student come to live with us. We found it very difficult to pronounce his name correctly, but he didn’t mind. He told us just to call him 'Eric'." A short story in pictures by

An Outsider's View
"Over the past fifty years, factions of biologists have had a complex relationship. Some scientists have continued to carry out relatively traditional natural history work, with little need to delve into molecular (or computational) biology. Others have given little attention to natural history, focusing their efforts instead on deciphering the complexities of a membrane channel, or building new algorithms for identifying open reading frames. In some cases, biologists have bridged this divide, and the result has been a fruitful collaboration. But in other cases—such as the DNA studies on whales and hippos—one group moves into the other's traditional territory, sparking new conflict."[

Getting up to speed
: "If it can get started, the California high-speed train would almost certainly be the most expensive single infrastructure project in United States history. Judging by the experiences of Japan and France, both of which have mature high-speed rail systems, it would end the expansion of regional airline traffic as in-state travelers increasingly ride the fast trains. And it would surely slow the growth of highway traffic."

"The Boyle Family
are a family of collaborative artists based in London. Their best known work, however, continues to be their Journey to the Surface of the Earth. Begun in 1964, this work encompasses many different series. Each of these series has involved various random selection techniques to isolate a rectangle of the Earth's surface. In the case of the World Series 1000 random selections were made from
a giant map of the world by blindfolded visitors. Once the random selection has been made, they recreate the site in a fixed and permanent form as a painted fibreglass relief. They recognise that each work is, in a sense, a failure. They know the selections can never be truly random and that it is impossible to eliminate themselves and their own subjective influences."

The Lecture System in Teaching Science
"Meanwhile, back at the classroom, the lecture is drawing to a close. Just as the bell rings, the lecturer, if he's a really smooth operator, comes to the end of a sentence, a paragraph, a nice neat unit. He lays down his last piece of chalk — he knows exactly how many pieces the lecture will take — picks up his precious lecture notes, and goes out. The students, tired but happy, rise up and follow after him. Their heads are empty, but their notebooks are full. Their necks are a little tired; it's been like a sort of vertical tennis match: board, notebook, board, notebook. But other than that, everything is all right. Any student will tell you, "I never had any trouble with the course until the first examination."" [

People of the Screen
: "Digital literacy’s advocates increasingly speak of replacing, rather than supplementing, print literacy. What is “reading” anyway, they ask, in a multimedia world like ours? We are increasingly distractible, impatient, and convenience-obsessed—and the paper book just can’t keep up. Shouldn’t we simply acknowledge that we are becoming
people of the screen, not people of the book?"

2008 Science and Engineering Visualization Challenge
"The

A new whale anti-collision system
"A remarkable feature of Andre's system is its ability to single out and track an individual whale among all its “family” members in the same area – a breakthrough made with the help of a West African musician. In attempting to unravel the chaotic rhythms of the sperm whale clicks, he was struck by the similarity between his underwater recordings and African tribal music. A Senegalese griot (drummer) confirmed the likeness and – amazingly – was able to pick individual whales from André’s recordings through their distinctive rhythmic structures."

Khaufpur
is a city of approaching a million souls situated at the absolute centre of India. The lakes around which our city is built were made a thousand years ago. Since that time the city was lost in jungles, rediscovered and
rebuilt. Again in the lifetime of those living, a terrible
calamity came upon this city, but again it has risen and continues toward a future filled with promise.

recreated some of these aerophones. Example sounds:

State of decay
:"Over the years, Boston artist
Rosamond Purcell has photographed goliath beetles and translucent bats culled from the backrooms of natural history museums; a collection of teeth pulled by Peter the Great; moles flayed by naturalist Willem Cornelis van Heurn; and scores of worn and weathered objects, like termite-eaten books and fish skeletons."

Keyboard calligraphy
"To produce such a typeface, Müteferrika knew he had to analyze Arabic script. Calligraphers might learn to make the correctly shaped letter combinations by practice, without conscious application of tens of thousands of rules, but for machine reproduction of the script, deciphering those rules was exactly what was essential."

Geoffrey Gurrumul Yunupingu
doesn't speak much, but when he takes up his guitar, he

Yolngu people.

The Mexican kitchen's Islamic connection
:"When Mexico’s leading writer, Nobel Prize laureate Octavio Paz, arrived in New Delhi in 1962 to take up his post as ambassador to India, he quickly ran across a culinary puzzle. Although Mexico and India were on opposite sides of the globe, the brown, spicy, aromatic curries that he was offered in India sparked memories of Mexico’s national dish, mole (pronounced MO-lay). Is mole, he wondered, “an ingenious Mexican version of curry, or is curry a Hindu adaptation of a Mexican sauce ?” How could this seeming coincidence of “gastronomic geography” be explained ?"

A Global Map of Human Impacts to Marine Ecosystems

How to say "I love you"
