Jabberwocky

“Jabberwocky” is a poem of nonsense verse written by Lewis Carroll, and was a part of his novel Through the Looking-Glass, and What Alice Found There (1872). The book tells of Alice’s travels within the back-to-front world through a looking glass.

While talking with the White King and White Queen (chess pieces), she finds a book written in a strange language that she can’t read. Understanding that she is travelling in an inverted world, she sees it is mirror-writing, finds a mirror, and holds it up to a poem on one of the pages, to read out the reflection of “Jabberwocky”. She finds it as puzzling as the odd land she has walked into, which we later discover is a dreamscape.

It is considered to be one of the greatest nonsense poems written in the English language, and became a source of nonsense words and neologisms such as “galumphing”, “chortle”, and “Jabberwocky” itself.

In 1855, when Carroll was 23, he printed the first stanza of the poem in Mischmasch, a periodical that Carroll wrote and illustrated himself for the amusement of his family. It was entitled “Stanza of Anglo-Saxon Poetry” and originally read:
“Twas bryllyg and ye slythy toves, Did gyre and gymble in ye wabe: All mimsy were ye borogoves; And ye mome raths outgrabe. ”
The spelling was altered when it was published as part of the later book.
The first stanza was written in Croft on Tees, close to nearby Darlington, where Carroll lived as a boy. The rest of the poem was written during Lewis Carroll’s stay with relatives at Whitburn, near Sunderland.
The story may have been partly inspired by the local Sunderland area legend of the Lambton Worm.

Roger Lancelyn Green suggests that “Jabberwocky” is a parody of the old German ballad “The Shepherd of the Giant Mountains” in which a shepherd kills a griffin that is attacking his sheep.
The ballad had been translated into English in blank verse by Lewis Carroll’s cousin Menella Bute Smedley in 1846, many years before the appearance of the Alice books.
Historian Sean B. Palmer suggests that Carroll was inspired by a section from Shakespeare’s Hamlet, citing the lines: “The graves stood tenantless, and the sheeted dead/Did squeak and gibber in the Roman streets” from Act I, Scene i.

John Tenniel reluctantly agreed to illustrate the book in 1871, and his illustrations are still the defining images of the poem.
The illustration of the Jabberwock may reflect the contemporary Victorian obsession with natural history and the fast-evolving sciences of palaeontology and geology.
Stephen Prickett notes that in the context of Darwin and Mantell’s publications and vast exhibitions of dinosaurs, such as those at the Crystal Palace from 1845, it is unsurprising that Tenniel gave the Jabberwock “the leathery wings of a pterodactyl and the long scaly neck and tail of a sauropod.”

Many of the words in the poem are playful nonce words of Carroll’s own invention, without intended explicit meaning.
Although the poem contains many nonsensical words, it holds to English syntax, and poetic forms are observed, such as the quatrain verses, the general abab rhyme scheme, and the iambic meter.
The linguist Lucas notes that the term “nonsense poem” is inaccurate. The poem relies on a distortion of sense rather than “non-sense”.

When Alice has finished reading the poem she gives her impressions:
‘It seems very pretty,’ she said when she had finished it, ‘but it’s rather hard to understand!’ (You see she didn’t like to confess, even to herself, that she couldn’t make it out at all.) ‘Somehow it seems to fill my head with ideas—only I don’t exactly know what they are! However, somebody killed something: that’s clear, at any rate’
This may reflect Carroll’s intention for his readership; the poem is, after all, part of a dream.

In later writings, he discussed some of his own created lexicon, commenting that he didn’t know his source for some of the words; the linguistic ambiguity and uncertainty throughout both the book and the poem may largely be the point.
In Through the Looking-Glass, the character of Humpty Dumpty gives comments on the non-sense words from the first stanza of the poem; however, Carroll’s personal commentary on several of the words differ from Humpty’s.
For example, following the poem, a “rath” is described by Humpty as “a sort of green pig”, whereas Carroll’s notes for the original in Mischmasch suggest a “rath” is “a species of Badger” that “lived chiefly on cheese” and had smooth white hair, long hind legs, and short horns like a stag.
The appendices to certain Looking Glass editions, however, state that the creature is “a species of land turtle” that lived on swallows and oysters.
Later commentators have added their own interpretations of the lexicon, often without reference to Carroll’s own contextual commentary.

In January 1868, Carroll wrote to his publisher Macmillan, asking, “Have you any means, or can you find any, for printing a page or two of the next volume of Alice in reverse?” This may suggest that Carroll was wanting to print the whole poem in mirror writing. Macmillian responded that it would cost a great deal more to do, and this may have dissuaded him

Multiple translations into Latin were made within the first weeks of Carroll’s original publication.

A Gossamer World

spider-webAugust Johann Rösel von Rosenhof (1705-1759)
Insecten-Belustigung

Two years ago, a research team led by the University of Oxford revealed that, when plucked like a guitar string, spider silk transmits vibrations across a wide range of frequencies, carrying information about prey, mates and even the structural integrity of a web.
Now, a new collaboration between Oxford and Universidad Carlos III de Madrid has confirmed that spider webs are superbly tuned instruments for vibration transmission.

Web-dwelling spiders have poor vision and rely almost exclusively on web vibrations for their ‘view’ of the world.
The musical patterns coming from their tuned webs provide them with crucial information on the type of prey caught in the web and of predators approaching, as well as the quality of prospective mates.
Spiders carefully engineer their webs out of a range of silks to control web architecture, tension and stiffness, analogous to constructing and tuning a musical instrument.

High-powered lasers were able to experimentally measure the ultra-small vibrations, which allowed the team to generate and test computer models using mathematical finite element analysis.

Professor Fritz Vollrath, Head of the Oxford Silk Group, added: ‘It is down to the interaction of the web materials, a range of bespoke web silks, and the spider with its highly tuned behaviour and armoury of sensors that allows this virtually blind animal to operate in a gossamer world of its own making, without vision and only relying on feeling. Perhaps the web spider can teach us something new about virtual vision.’

A Marmoset Taking Sweets on a Painted Commode

marmoset-teacupLouis Tessier (c.1719 – 1781)

 

“Virtually every ‘uniquely human’ characteristic has turned out not to be so”, Matthew Cobb, The Guardian


by

It used to happen every day at the London Zoo: Out came the dainty table and chairs, the china cups and saucers — ­afternoon tea, set out for the inhabitants of the ape enclosure to throw and smash. It was supposed to be amusing — a ­comic, reckless collision of beasts and high ­culture. But, as Frans de Waal explains in “Are We Smart Enough to Know How Smart Animals Are?”,  apes are actually innovative, agile tool-users.
Not surprisingly — to de Waal, at least — the apes in London quickly mastered the teacups and teapot too. They sat there civilly, having tea.
“When the public tea parties began to threaten the human ego, something had to be done,” de Waal writes. “The apes were retrained to spill the tea, throw food around, drink from the teapot’s spout,” and so on.
The animals had to be taught to be as stupid as we assumed they were. But, of course, the fact that they could be taught to be stupid is only more perverse evidence of their intelligence.

For centuries, our understanding of animal intelligence has been obscured in just this kind of cloud of false assumptions and human egotism.
De Waal painstakingly untangles the confusion, then walks us through research revealing what a wide range of animal species are actually capable of.
Tool use, cooperation, awareness of individual identity, theory of mind, planning, metacognition and perceptions of time — we now know that all these archetypically human, cognitive feats are performed by some animals as well.
And not just primates: By the middle of ­Chapter 6, we’re reading about cooperation among leopard coral trout.

There are many different forms of intelligence; each should be valuated only relative to its environment. And yet, there’s apparently a long history of scientists ignoring this truth.
They’ve investigated chimpanzees’ ability to recognize faces by testing whether the chimps can recognize human faces, instead of faces of other chimps. (They do the former poorly and the latter quite well.)
They’ve performed the ­famous mirror test — to gauge whether an animal recognizes the figure in a mirror as itself — on elephants using a too-small, human-size mirror.
Such blind spots are, ultimately, a failure of empathy — a failure to imagine the experiment, or the form of intelligence it’s testing for, through the animal’s eyes. De Waal compares it to “throwing both fish and cats into a swimming pool” and seeing who can swim.

We sometimes fall into what de Waal calls “neo-creationist” thinking: We accept evolution but assume “evolution stopped at the human head” — believing our bodies may have evolved from monkeys, but that our brains are their own miraculous and discrete inventions.
But cognition must be understood as an evolutionary product, like any other biological phenomenon; it exists on a spectrum, de Waal argues, with familiar forms shading into absolutely alien-looking ones. He introduces what he calls the rule of “cognitive ripples”:
We tend to notice intelligence in primates because it’s most conspicuous, it looks the most like our intelligence.
“After the apes break down the dam between the humans and the rest of the animal kingdom, the floodgates often open to include species after species.”

 

 

It Could Take a Century to Recover

Study finds extremely slow reproduction rate unable to keep pace with deaths

African forest elephants have experienced serious poaching, driving an estimated population decline of 65% between 2002 and 2013.
Their low birth rates mean that it will take forest elephants at least 90 years to recover from these losses, according to researchers from the Wildlife Conservation Society, the Cornell Lab of Ornithology’s Elephant Listening Project, Colorado State University, and Save the Elephants.

These findings are from the first-ever study of forest elephant demography just published in the Journal of Applied Ecology.

“Female forest elephants in the Dzanga population typically breed for the first time after 23 years of age, a markedly late age of maturity relative to other mammals. In contrast, savannah elephants typically begin breeding at age 12.
In addition, breeding female forest elephants only produced a calf once every five to six years, relative to the three to four-year interval found for savannah elephants.”
Andrea Turkalo, a Wildlife Conservation Society scientist, collected the detailed data on the elephants over several decades, in spite of tough logistical challenges and political instability.
“This work provides another critical piece of understanding regarding the dire conservation status of forest elephants.”

George Wittemyer, a professor in Wildlife Conservation at Colorado State University said, “Legislation regarding ivory trade must consider the collateral effects on forest elephants and the difficulties of protecting them. Trade in ivory in one nation can influence the pressures on elephants in other nations.”
And the forest elephant is particularly susceptible to poaching.

Forest elephants also have critical ecological roles in Central African forests, and many tree species rely on the elephants to disperse their seeds.
Those forests are vitally important for absorbing climate change gases.

Surrendering Forests

tree david johnsonDavid Johnson (1827 – 1908)


by Jeff Tietz
Rolling Stone

From a tree’s perspective, excessive heat may be as deadly as lack of water.
To photosynthesize, a tree opens pores in its leaves called stomata and inhales CO2. Solar-charged chemical reactions then transform the CO2 into carbohydrates — the raw stuff of leaves and wood. During this process, a fraction of the tree’s internal water supply evaporates through its stomata, creating the negative pressure that pulls water from the soil into the tree’s roots, through its trunk and up to its canopy. But heat juices the rate at which trees lose moisture, and that rate escalates exponentially with temperature — so small temperature increases can cause a photosynthesizing tree to lose dangerous amounts of water.
“Forests notice even a one-degree increase in temperature,” says Park Williams at Los Alamos National Laboratory.

In the death scenario, the sky sucks water from the leaves faster than it can be replaced by water in the soil, and the resulting partial vacuum fatally fractures the tree’s water column. If a tree closes its stomata to avoid this, shutting down photosynthesis, it risks starvation.
Ultimately, the tree’s cellular chemistry will fail, but it will often die before that, as its defenses fall; the complexly toxic sap that repels predatory insects dries up.
Many insects can detect diminished sap levels within tree bark by scent — they smell drought stress and pheromonally broadcast news of deteriorating tree health. Other defenses – against microbes, for example — may also be compromised.
A hotter climate generally means more insects.
It also means more, and more intense, wildfires.

For decades, all over the planet, heat-aggravated drought has been killing trees: mountain acacia in Zimbabwe, Mediterranean pine in Greece, Atlas cedar in Morocco, eucalyptus and corymbia in Australia, fir in Turkey and South Korea.
In 2010 a group of ecologists published the first global overview of forest health. They described droughts whose severity was unequaled in the “last few centuries” and documented “climate-driven episodes of regional-scale forest die-off.”

Because global warming outpaces evolutionary adaptation, the question is: Can trees survive as they are?
The conifer forests of the Southwest United States, if climate projections are even minimally accurate, cannot, but what about the rest of the world’s forests?
That’s a critical question, because forests cover more than a quarter of the planet’s land, and they help stabilize the climate by pulling immense quantities of CO2 out of the air.
In August 2011, a team of scientists led by Dr. Yude Pan, a U.S. Forest Service researcher, reported that between 1990 and 2007, forests sequestered about 25 percent of all greenhouse-gas emissions — everything not in the air or seas.

Climatologists worry that if forests across the planet deteriorate, they could, on balance, begin releasing as much carbon as they absorb.
One of Pan’s collaborators, Dr. Richard Birdsey: “If the carbon sink in forests fails, a simple speculation is that global temperatures would increase proportionally to the increase of CO2 concentration, so about 25 percent above current climate projections.”
“The more forests die, the less carbon they take out of the air, the warmer it gets, the more forests die,”
says Dr. Nate McDowell at Los Alamos. “It’s a thermostat gone bad.”

The better we understand climate change, the more we seem to find that warming begets warming in unexpected and self-amplifying ways: Implacable heat engines materialize and run independently of all human effort.

There are an estimated 1 trillion metric tons of frozen carbon in the soils of the Arctic region — a century’s worth of global emissions, twice the amount stored in the global forest, another few Industrial Revolutions.
As the planet warms, permafrost thaws and decomposes, sending carbon into the air and further warming the planet. Higher temperatures also kindle increasingly intense and frequent wildfires in high-latitude forests, to quadruple effect.
And fire releases carbon directly; it burns off the insulating upper layer of vegetation, exposing more permafrost to warm air; it blackens the trees and land, which consequently absorb more solar radiation; and its soot can settle on and darken snow and ice sheets to the north, which then also absorb more solar radiation.

By the end of the century, the woodlands of the Southwest will likely be reduced to weeds and shrubs. And scientists worry that the rest of the planet may see similar effects.

A Beautiful Law of Nature

camouflage caterpillarAbbott Handerson Thayer (August 12, 1849 – May 29, 1921)

 

“Less Thing-Like”

Abbott Thayer was a lifelong wildlife advocate whose artistic focus never strayed far from his personal fascination with the natural world.

On 11 November 1896 he made an appearance at the Annual Meeting of the American Ornithologists’ Union in Cambridge, Massachusetts arriving at the Harvard Museum of Comparative Zoology on Oxford Street bearing a sack of sweet potatoes, oil paints, paintbrushes, a roll of wire, and two new principles of invisibility in nature that together formed his “Law Which Underlies Protective Coloration.”
In his afternoon open-air lecture, Thayer argued that every non-human animal is cloaked in an outfit that has evolved to obliterate visual signs of that animal’s presence in its typical habitat at the “crucial moment” of its utmost vulnerability.

Thayer arrived at camouflage inadvertently, in the process of pursuing art.
As a student, he had learned that any shape drawn on a flat surface can be given volume and dimension by a venerable process called shading. This is reliably achieved by rendering the shape lighter on the top and gradually darker toward the bottom.
As we know from current brain research, this takes advantage of an inborn visual tendency called the top-down lighting bias: when we look at anything, we default to the assumption that its light source is coming from overhead.

Observation then enabled him to realize why so many animals have light colored bellies with darker coloring toward the tops of their bodies. The effect is the inverse of shading.
Appropriately, it became known as countershading, because the effect counteracts the shadows resulting from cast sunlight, making an animal look less dimensional, less solid, less “thing-like.”
Though some of Thayer’s other proposals have been disregarded, countershading is a widely accepted biological principle today, and stands as the artist’s most significant contribution to the natural sciences.

By 1896, Thayer was increasingly inserting himself into what was a longstanding debate over the origins, effectiveness, and pervasiveness of protective concealment in the natural world.
After the publication of Charles Darwin’s Origin of Species in 1859, animal coloration—both its origins and its role in animal behavior—had become a key locus of debate among natural historians, artists, and the lay public.
Prior to this period, naturalists had noted instances of animals’ blending in with their backgrounds. It seemed remarkable that God had “dropped” them into place just so—“nature by design.”

By contrast, in an evolutionary model, there was a gradual “fitting together” over time. Evolutionary theories, both Darwin’s and that of his colleague Alfred Russel Wallace, presented a range of explanations for animal colors. Darwin emphasized interrelations between the sexes as the cause of the showy coloration found in the male of many species; females chose the more colorful males for mating.
Wallace, studying the colors of many insects, interpreted bright hues and complex patterns alike as either warning signals to potential predators, modes for assimilation in the environment, or mimicry of other, more dangerous, species.

Meanwhile,  philosopher-psychologist William James, a friend of Thayer’s and a fellow birder, discussed the experience of bird watching in his 1890 Principles of Psychology, describing the study of illusions, or so-called “false perceptions,” as critical in efforts to understand human apprehension of depth, color, and movement.

Thayer’s New Hampshire summer home, to which he and his family relocated around 1900, was transformed into a year-round laboratory for studying protective coloration.
His communion with nature permeated the entire household. Wild animals—owls, rabbits, woodchucks, weasels—roamed the house at will. There were pet prairie dogs named Napoleon and Josephine, a red, blue and yellow macaw, and spider monkeys

Soon, his wife Emma, son Gerald, and daughters Mary and Gladys joined him as fellow investigators, technicians, and artisans.
Between 1901 and 1909, their generative theories were built up into a universe of paintings, photography (a new technology), collages, stencils, and essays. Each format addressed the enigmas of coloration and invisibility in different ways.

Thayer was simultaneously producing, witnessing, and documenting the processes of a living being’s assimilation into its habitat.

Rocks in Unrest

 

Phoebe Sarah Marks in Hampshire, England,  was born on 28 April 1854. She was the third child of a Polish-Jewish watchmaker named Levi Marks, an immigrant from Tsarist Poland; and Alice Theresa Moss, a seamstress. Her father died in 1861, leaving Sarah’s mother with seven children and an eighth expected. Sarah took up some of the responsibility for caring for the younger children.
At the age of nine, Sarah was invited by her aunts, who ran a school in London, to live with her cousins and be educated with them.
In her teens she adopted the name “Hertha” after the heroine of a poem by Algernon Charles Swinburne that criticized organised religion.

By age 16, she was working as a governess, but  George Eliot supported Ayrton’s application to Girton College, Cambridge.
Eliot was writing her novel Daniel Deronda at the time. One of the novel’s characters, Mirah, was said to be based on Ayrton.
During her time at Cambridge, Ayrton constructed a sphygmomanometer, led the choral society, founded the Girton fire brigade, and, together with Charlotte Scott, formed a mathematical club. In 1880, Ayrton passed the Mathematical Tripos, but Cambridge did not grant her an academic degree because, at the time, Cambridge gave only certificates and not full degrees to women.

Upon her return to London, Ayrton earned money by teaching and embroidery, ran a club for working girls, and cared for her invalid sister.
She was also active in devising and solving mathematical problems, many of which were published in “Mathematical Questions and Their Solutions” from the Educational Times.
In 1884 Ayrton patented a line-divider, an engineering drawing instrument for dividing a line into any number of equal parts and for enlarging and reducing figures. Its primary use was likely for artists for enlarging and diminishing, but it was also useful to architects and engineers. From then until her death, Hertha registered 26 patents.

That year Ayrton began attending evening classes on electricity at Finsbury Technical College, delivered by Professor William Edward Ayrton, a pioneer in electrical engineering and physics, and a fellow of the Royal Society.
In 1899, she was the first woman ever to read her own paper before the Institution of Electrical Engineers. Her paper was entitled “The Hissing of the Electric Arc”. Shortly thereafter, Ayrton was elected the first female member; the next woman to be admitted to the IEE was in 1958.
She petitioned to present a paper before the Royal Society but was not allowed because of her sex, and “The Mechanism of the Electric Arc” was read by John Perry in her stead in 1901.
Ayrton was also the first woman to win a prize from the Society, the Hughes Medal, awarded to her in 1906 in honour of her research on the motion of ripples in sand and water and her work on the electric arc.

By the late nineteenth century, Ayrton’s work in the field of electrical engineering was recognised more widely. At the International Congress of Women held in London in 1899, she presided over the physical science section, and she spoke at the International Electrical Congress in Paris in 1900. Her success there led the British Association for the Advancement of Science to allow women to serve on general and sectional committees.

Ayrton’s interest in vortices in water and air inspired the Ayrton fan, used in the trenches in the First World War to dispel poison gas.
She helped found the International Federation of University Women in 1919 and the National Union of Scientific Workers in 1920.

Two years after her death in 1923, Ayrton’s lifelong friend Ottilie Hancock endowed the Hertha Ayrton Research Fellowship at Girton College, which continues today.

Guinea Pig

The earliest known written account of the guinea pig dates from 1547, in a description of the animal from Santo Domingo.
Based on excavations on West Indian islands, it seems that the animal must have been introduced by ceramic-making horticulturalists from South America to the Caribbean around 500 BC, and it was present in the Ostionoid period, for example, on Puerto Rico, long before the advent of the Spaniards.
The guinea pig was first described in the West in 1554 by the Swiss naturalist Conrad Gessner.
