Review: Treasures from the Map Room

by Jonathan Crowe

treasures-map-room-obliqueIf all maps must necessarily be selective, choosing what to show and what to leave out, surely map books must do the same. That thought came to mind as I perused Treasures from the Map Room—no relation—a book that presents maps from Oxford University’s Bodleian Library, collected and curated by the Bodleian Map Room’s senior library assistant, Debbie Hall.

“Although maps have formed part of the Bodleian’s collections from early on, they have been collected actively only since around 1800,” Hall writes in the introduction. Broadly speaking, the Bodleian’s map holdings come from a combination of bequests and legal deposit requirements. The latter in particular means that the Bodleian’s holdings of British maps—including virtually every Ordnance Survey map and a large number of commercially published maps—are very extensive. The bequests are sometimes much better known: maps named for their owners and donors rather than their creators—the Gough Map, the Selden Map—falling into the Bodleian’s hands.

Hall organizes her selection—some 75 maps—into seven chapters organized by theme: Travel and Exploration, Knowledge and Science, Pride and Ownership, Maps of War, The City in Maps, Maps for Fun, and Imaginary Lands. Sometimes those themes make for unlikely juxtapositions: Hall mentions the Tabula Peutingeriana and American highway maps in very nearly the same breath; and Maps for Fun, a chapter dealing with tourism, recreation and travel, includes a 15th-century Holy Land pilgrimage map—Reuwich’s Peregrinatio in Terram Sanctam—alongside the MountMaps 3D Navigator Map. But apart from that the chapters present us with some very interesting maps indeed: Travel and Exploration gives us the Gough and Selden maps; Knowledge and Science discusses Mercator, Ortelius and early astronomical maps, John Speed, Christopher Saxton and the Ordnance Survey; Maps of War gives us fortifications and plans, siege and trench maps, but also silk escape maps of World War II; Imaginary Lands ranges from Hole’s Poly-Olbion maps to Leo Belgicus, Tolkien and Lewis, and the art of Layla Curtis.

We get, in other words, a taste of just about everything—but only a taste. The breadth of Treasures of the Map Room is both a blessing and a curse. We’re made aware of the volume and diversity of the Bodleian’s map holdings, but we never get a chance to drill down beyond the most cursory of examinations, never more than one example of something. On the other hand, Hall’s approach brings to the fore maps that might not otherwise be included in books like this—books that can privilege the rare and the ancient over the more mundane but more significant. For example, the map I found myself staring at the most was the 1864 Ordnance Plan of the Crystal Palace and its Environs, a 1:2,500 map of incredible detail and delicacy. You might find yourself lingering over some other map. Discoveries like this are, I suspect, the whole point of book that is, after all, about a library’s hidden treasures.

I received a review copy from the North American distributor for this book, the University of Chicago Press.

Treasures of the Map Room edited by Debbie Hall (Oxford: Bodleian Library, 2016). Hardcover, 224 pp., £35/$60. ISBN 978-1-85124-2504. Buy at Amazon.

The planet is a big, wobbly top — and melting ice is changing how it spins

by Brian Kahn

earth axis tilt

The spin of the earth is a constant in our lives. It’s quite literally why night follows day.

And while that cycle isn’t going away, climate change is messing with the axis upon which our fair planet spins. Ice melting has caused a drift in polar motion, a somewhat esoteric term that tells scientists a lot about past and future climate and is crucial in GPS calculations and satellite communication.

Before 2000, Earth's spin axis was drifting toward Canada (left globe). Climate change-driven ice loss in Greenland, Antarctica and elsewhere is pulling the direction of drift eastward.

Polar motion refers to the periodic wobble and drift of the poles. It’s been observed for more than 130 years, but the process has been going on for eons driven by mass shifts inside the earth as well as ones on the surface. For decades, the north pole had been slowly drifting toward Canada, but there was a shift in the drift about 15 years ago. Now it’s headed almost directly down the Greenwich Meridian (sorry Canada, no pole for you, eh).

Like many other natural processes large and small, from sea levels to wildfires, climate change is also playing a role in this shift.

“Since about 2000, there has been a dramatic shift in this general direction,” Surendra Adhikari, a researcher at NASA’s Jet Propulsion Laboratory, said. “It is due to climate change without a doubt. It’s related to ice sheets, in particular the Greenland ice sheet.”

That ice sheet has seen its ice loss speed up and has lost an average of 278 gigatons of ice a year since 2000 as temperatures warm. The Antarctic has lost 92 gigatons a year over that time while other stashes of ice from Alaska to Patagonia are also melting and sending water to the oceans, redistributing the weight of the planet.

Adhikari and his colleague Erik Ivins published their findings in Science Advances on Friday, showing that melting ice explains about 66 percent of the change in the shift of the Earth’s spin axis, particularly the rapid losses occurring in Greenland.

It’s a huge, mind boggling process on the global scale, but imagine it like a top. Spinning a top with a bunch of pennies on it will cause wobble and drift in a certain pattern. If you rearrange the pennies, the wobble and drift will be slightly different.

That’s essentially what climate change is doing, except instead of pennies, it’s ice and instead of a top, it’s the planet. Suffice to say, the stakes are a little higher.

Ice loss explains most but not all of the shift. The rest can mostly be chalked up to droughts and heavy rains in certain parts of the globe. Adhikari said this knowledge could be used to help scientists analyze past instances of polar motion shifts and rainfall patterns as well as answer questions about future hydrological cycle changes.

Ice is expected to continue melting and with it, polar motion is expected to continue changing as well.

“What I can tell you is we anticipate a big loss of mass from West Antarctic and Greenland ice sheets and that will mean that the general direction of the pole won’t go back to Canada for sure,” Adhikari said.

If it continues moving down the Greenwich Meridian or meanders another way remains to be seen, though.

“This depends highly on the region where ice melts, or if the effect of ice melt would be counterbalanced by another effect (for example sea level rise, increased water storage on continents, changes of climate zones),” Florian Seitz, the director of German Geodetic Research Institute, said in an email.

In the here and now, polar motion shifts matter for astronomical observations and perhaps even more importantly for the average person, GPS calculations.

Drought-sensitive butterflies face 'widespread extinction' in UK

by LiveScience
Butterfly
Feed-twFeed-fb

Green-veined white butterflies with pale-yellow wings, among other butterfly species, could disappear from southern Britain in the next 35 years if climate change and habitat loss continue, according to new research.

"The results are worrying," Tom Oliver, lead author of the study and an ecological modeler at the Center for Ecology & Hydrology in Oxfordshire, United Kingdom, said in a statement. "For drought-sensitive butterflies, and potentially other taxa [group of organisms], widespread population extinctions are expected by 2050."

Climate models predict that higher levels of atmospheric greenhouse gases, like carbon dioxide, will intensify weather events, meaning summers could get much hotter and drier in some parts of the world. Read more...

LONDON — While most of us were tucked up in our beds, the serious sky watchers were out in the great outdoors, many with cameras in tow to capture some of the best of what the Perseid meteor shower had to offer

The show, which happened between late Wednesday night and early Thursday morning, was particularly spectacular with the moon close to its new phase, which meant that light reflected by it didn't block out faint meteors from being seen

Photographers across Britain, Northern Ireland and Ireland managed to snap some stunning captures. Here are some of the best of them. Read more...

Foggy Forests of Ancient Trees Pruned for Charcoal in Basque Country Photographed by Oskar Zapirain

by Christopher Jobson

fores-2

top-net

Oskar Zapirain's photographs capture eerie forests cast in thick fog, hazy light descending upon the foliage in the same green shade that blankets the floor in moss. Zapirain has been attracted to this landscape for years because of the homogenous light as well as the way it forces the viewer directly into a mystical atmosphere.

The forest Zapirain features is a beech forest in Oiartzun, Basque Country in Northern Spain. This particular forest is unique due to the history charcoal production within the region. Instead of clearcutting like we do today, the trees were instead pruned to preserve the trees and maintain the integrity of the forest across generations. The trees have since regrown with short trunks and dramatically long limbs that shoot outward like arms from almost every angle, adding a ghostly feel to each of Zapirain’s photos. You can explore more of his work on Flickr.

The Original, Real-Life Dystopian Cityscape of Kowloon Walled City, and the Artwork It Inspired

Kowloon Walled City was a crazy social experiment, except there were no scientists in charge; the test subjects were.

On the site of a dismantled Chinese fortress in Hong Kong, refugee squatters began building makeshift homes in the 1940s. What started out as 2,000 refugees in huts gradually grew into 50,000 people crammed into ramshackle, unregulated skyscrapers leaning on each other for support. (It's reported that no architects or engineers were involved in building the structures, which went up to 14 stories, but were somehow erected by the community that lived there.) And amazingly, it all formed a cohesive—and largely contiguous—structure, resembling a castle or fortress.

KWC had water and electricity siphoned from wells and the rest of the city, but was an unregulated mess of ad-hoc infrastructure largely unsupported by government. Police were afraid to venture inside (though unbelievably, postman were reportedly forced to deliver mail there!). It was filled with criminals, drug dealers and prostitutes, as well as honest families, schoolchildren and one-man manufacturing shops. The following illustration shows what a slice of it might look like:

Larger version of this image is viewable here

Tiny, cramped spaces did double duty, with units that were classrooms during the day transformed into strip clubs at night. There were restaurants and gambling dens, hair salons and convenience stores, unlicensed doctors and dentists. So close were the buildings that sunlight was hard to come by on street level; thus fluorescents were hung outdoors at ground level for illumination. Rooftops, meanwhile, became social spaces.

The government finally shut it down in the 1990s and razed it. But in the years during and since, Kowloon Walled City has captured the imaginations of everyone from architects to sci-fi authors to set designers to artists.

Speaking of artists, photographer Greg Girard, who documented KWC in the 1980s, probably has the best photo essay on it (shot both inside and outside) right here. We also wanted to show you the fantastic KWC-inspired work done by a handful of illustrators:

Incredibly Creative Stop-Motion Film Made with Only Rubber Bands & Thumbtacks

by DL Cade

It’s been a while since we’ve shared a stop-motion film, but ‘A Girl Named Elastika’ by French filmmaker Guillaume Blanchet was a no-brainer. At once simple (equipment wise) and incredibly complex (how long did it take to move all those thumbtacks!?) the video is impressive from start to finish.

And fortunately for Blanchet, we’re not the only ones that think this. The video only made it to Vimeo a couple of days ago, but over the last year he has been collecting animation awards left and right for something that was created almost entirely on a bulletin board!

Screen Shot 2014-04-03 at 7.51.11 AM

Unfortunately there’s no behind the scenes video or list of gear used or really any other information about the project other than this tongue-in-cheek Vimeo description:

She’s young, dreamy and fearless, she drives cars way too fast, she’s also a yamakasi. She likes adventure, fireworks and unrelenting seas. From the day I conceived her, I’ve been a worried father. And a proud one too.

Don’t get us wrong, we love a good joke, but we’re also hoping to get some more technical info about how this all came together.

If you haven’t already, check out the video at the top, and then head over to Blanchet’s website or Facebook to see more of his work and keep up with him as he sets off on his next project.

Fourth Annual AOSS Photo Contest: Announcing the Winners

by billb

by Leanne Avila

Steam fog rising from a Montana lake, methane bubbling up in Lake Mendota only to be trapped in ice to form “pancakes,” a rare glimpse of an aurora borealis from our iconic rooftop… For the fourth year in a row, staff and students in the Atmospheric, Oceanic, and Space Sciences (AOSS) building have sought to capture the beauty and natural forces of weather for the AOSS Photo Contest.

Administered by the Space Science and Engineering Center (SSEC), the contest invited weather photographers to submit photos representing a “weather event, anywhere in the world.” This year 18 individuals submitted 32 photos. While many of the images focused on winter weather in Wisconsin, they take us across the country and even around the globe, simultaneously showcasing each scene’s unique artistry and the allure of weather phenomena.

The winners of the contest are:

  • 1st place: Bill Bellon for Steam Fog over Fort Peck Lake in NE Montana
  • 2nd place: Hank Revercomb for Lake Mendota Methane Pancakes
  • 3rd place: Dave Jones for A Near Miss
  • Honorable mentions:
    • Dave Stettner for Smoke and Lenticular Clouds over Denali
    • John Lalande for SSEC Direct Broadcast Antenna and Aurora Borealis

Photos will be on display in the gallery outside the Schwertdtfeger Library, located on the 3rd floor of AOSS, throughout the year.

Can we save Chesapeake Bay from chicken crap?

by John Upton
chicken factory farm

It sucks to be crapped on by a bird. So imagine being crapped on by hundreds of millions of them every year.

That’s the reality for Chesapeake Bay.

In the adjacent state of Maryland, more than 300 million chickens in factory farms produce more than a billion and a half pounds of waste every year. Most of that waste is spread over farmland — ostensibly as a fertilizer, but that just happens to be the cheapest way of disposing of all that crap. Now almost half the farms in the state are saturated with phosphorous from the manure; that phosphorus runs off the farms and into the estuary and bay, where it fertilizes algal blooms that threaten the seafood and tourism industries.

Last year, Maryland Gov. Martin O’Malley (D) backed away from proposed new regulations to deal with the problem, caving to pressure from the poultry industry. But now two state lawmakers have stepped up by introducing legislation that would compel poultry companies to pay to help protect and restore Chesapeake Bay.

“Poultry companies are polluting with impunity while the public pays for the cleanup,” said one of the lawmakers, Shane Robinson, a Democrat.

The Poultry Fair Share Act would tax poultry companies five cents per bird, with revenue used to cover most of the $20 million annual cost of a state program that helps farmers grow cover crops to reduce soil erosion and nutrient runoff.

According to Food & Water Watch, which has advocated for such legislation, Maryland residents pay $110 million of taxes every year into a bay restoration fund. “Meanwhile, a company like Perdue enjoys annual chicken sales of $4.8 billion and pays nothing into the fund despite the significant impacts the industry has on the health of the Bay,” the nonprofit wrote on its website.

Poultry companies are making the ridiculous claim that the five-cent tax would utterly ruin their industry, which is a big employer in the state. “That bill, if passed, will guarantee that there won’t be any poultry left in the state of Maryland,” one of them told The Daily Times.

When the legislation was being floated in November, a Perdue spokesman dismissed the proposal as “part of an ongoing campaign by radical environmental groups against contemporary animal agriculture.”

If contemporary animal agriculture means dumping shit-derived nutrients into treasured water bodies, ruining water quality and the industries that rely on it, then we’ll take the old variety of agriculture, please.

China is far and away the largest consumer of tea, at 1.6 billion pounds a year. But per person, as illustrated in the map above, the picture is a lot different: Turkey, Ireland, and the United Kingdom are home to the world’s biggest tea drinkers.

The Turkish, for one, don’t merely enjoy drinking tea; they downright adore the stuff. Turkey’s nearly 7 pounds per person per year is easily the largest in the world. Here’s the full list:

These photos of glowing beaches are seriously stunning

by hrichmond

Meet bioluminescent phytoplankton, the fireflies of the sea. When the li’l marine microbes get stressed out — say, by crashing waves or you rowing your boat over them — they glow in the dark. Bad for them, but good for anybody who appreciates an algae bloom of fluorescent Smurf dandruff!

Taiwanese photographer Will Ho took the above shots of bioluminescent phytoplankton while on vacation in the Maldives. Here’s another gorgeous one, taken in Pacifica, California, by San Francisco photographer Charles Leung:

Scientists are still working out how and why this magic blue ocean-starlight happens, but those slowpokes are making progress, according to NatGeo:

The most common type of marine bioluminescence is generated by phytoplankton known as dinoflagellates. A recent study co-authored by [Harvard biologist Woodland] Hastings has for the first time identified a special channel in the dinoflagellate cell membrane that responds to electrical signals — offering a potential mechanism for how the algae create their unique illumination.

The first high-res HD video of Earth from space is amazing and kind of unnerving

by jesszimmerman
skybox

This is the world’s first high-resolution HD video of the planet taken from space, and it’s visually amazing (change the quality to 1080p to see it in full-resolution):

But also maybe kind of a little alarming? Skybox Imaging, which took the video, assures us all that the applications are benevolent and the resolution isn’t high enough for them to watch you get undressed:

The resolution is high enough to view objects like shipping containers that impact the global economy while maintaining a level of clarity that does not determine human activity … The business applications for satellite imagery and now, dynamic satellite video, are innumerable – ranging from supply chain monitoring to maritime awareness, industrial plant activity monitoring to environmental and humanitarian relief monitoring. 

However, we’ve seen Real Genius and you know we’re thinking about this:

And this:

Although actually, that second one doesn’t seem so bad — maybe we can get the satellite to make us some popcorn to eat while we watch the awesome HD satellite video.

Veja o horizonte, olhe para cima

by Da redação de Casa Vogue

  (Foto: Romain Jacquet-Lagreze)
Nas grandes metrópoles os prédios não param de ficar cada vez mais altos. Agora junte os cenários urbanos ao olhar precioso de um fotógrafo. Foi o que fez o francês Romain Jacquet-Lagreze ao clicar esses momentos e reunir as imagens no livro Vertical Horizon,160 páginas. Porque tão lindo quanto olhar para cima e ver um belo céu é ter como moldura arranha-céus de tirar o fôlego.

Quando o artista mudou-se para Hong Kong o hábito de olhar para o alto começou a ser feito com mais frequência. “Sempre o pratiquei em florestas, mas aqui passei a ver os edifícios por outros ângulos. Aos poucos fui fotografando o que via e isso acabou por se transformar em um projeto”. Romain passou então a explorar muitas áreas da cidade até conseguir imagens de grande parte dos distritos.

Seu olhar sobre uma das cidades mais verticalizadas do mundo foi apelidado, por ele, de corrida arquitetônica para o céu. O trabalho reflete essa visão de competitividade no skyline de Hong Kong, mas também tem o objetivo de estimular a reflexão nas pessoas. “Nossas vidas são como edifícios: começamos de baixo, querendo alcançar o céu, mas para isso é fundamental criarmos bases sólidas”, conta Romain. Além disso, o francês quer chamar a atenção para os detalhes que passam desapercebidos devido à correria do dia-a-dia. Para ele existem muitos horizontes que não levam somente à luz no final do túnel, e o horizonte vertical é apenas um deles – talvez um dos mais belos.

Nmap6 cheatsheet

by Alejandro Ramos
Han pasado ya 3 añazos desde que liberásemos la chuleta para Nmap 5 en este mismo blog. Más de 33.000 descargas de los PDF y decenas de versiones nuevas de la herramienta.

Tampoco es que haya cambiado demasiado en todo este tiempo, un par de parámetros se han renombrado (como el caso de -sP que pasa a ser -sn o -P0 que se convierte en -Pn). También he añadido la opción  --script-updatedb que actualiza los scripts NSE de la herramienta a su última versión.

Los ejemplos de ejecución los mantengo porque me siguen pareciendo adecuados, aunque con los cambios arriba mencionados:

Análisis rápido: nmap -T4 -F
Análisis rápido (puerto 80): nmap -T4 --max_rtt_timeout 200 --initial_rtt_timeout 150 --min_hostgroup 512 --max_retries 0 -n –Pn -p80
Análisis de ping: nmap -sn -PE -PP -PS21,23,25,80,113,31339 -PA80,113,443,10042 --source-port 53 -T4
Exhaustivo lento: nmap -sS -sU -T4 -A -v -PE -PP -PS21,22,23,25,80,113,31339 -PA80,113,443,10042 -PO --script all
Trazado de ruta rápido:  nmap -sn -PE -PS22,25,80 -PA21,23,80,3389 -PU -PO --traceroute

Today the Department of Unexpected Interspecies Friendship shows us a real life example of The Fox and the Hound currently taking place in a forest in Norway. Sniffer the wild fox and Tinni the domestic dog first met by chance while Tinni was out for a walk with his human, photographer Torgeir Berge. The unlikely pair became fast friends and now Torgeir photographs their heartwarming daily encounters. Sniffer and Tinni frolic in their secluded woodland playground until they’ve tired each other out, at which point they settle down and relax together.

The tender and playful relationship between the two is captured in these photos and Berge was so inspired by it that he decided to release a book chronicling the canine duo called The Fox and the Dog which will feature fairytales based on their friendship.

More so, Berge noted how similar his dog and Sniffer were and his thoughts on Norway’s controversial fox-fur trade changed so much that he is now campaigning to have it banned. Berge observed ‘how similar foxes and dogs actually are’ and labels the fox, the ‘dog of the forest’.

Berge will donate a large portion of the proceeds from the book to help his conservation and anti-fur trade campaign.

In addition to their book, Sniffer and Tinni also have their own Facebook page where you can follow their ongoing adventures.
