Our thanks to Deanna Frautschi in Illinois for this wonderful winter sunset photo. She wrote:

January sunset in central Illinois highlights the breathtaking beauty of the sky and the land.

Many people in various parts of the U.S. comment that the winter sunsets are the most spectacular. Why is that? The Weather Channel says it’s because, at this time of year in North America, weather patterns let dry, clean Canadian air sweep across country. In that winter air, more colors of the rainbow spectrum that makes up sunlight travel through to our eyes without being scattered away.

Image of the Day…. Interior View of International Space Station…!!!

This image of the interior view from the International Space Station’s Cupola module was taken on Jan. 4, 2015. The large bay windows allows the Expedition 42 crew to see outside. The Cupola houses one of the space station’s two robotic work stations used by astronauts to manipulate the large robotic arm seen through the right window. The robotic arm, or Canadarm2, was used throughout the construction of the station and is still used to grapple visiting cargo vehicles and assist astronauts during spacewalks. The Cupola is attached to the nadir side of the space station and also gives a full panoramic view of the Earth.

Trees are poems that the earth writes upon the sky.

Kurt Harvey captured this image in Yosemite National Park in California. He wrote:

I’ve admired this tree many times while driving along the Tioga Pass Road in Yosemite. Rooted in a crack on the slope of a granite dome it has a grand view and is also very exposed to the wind. It looks like its doing well though and is inspiring to see.

This was made from a 3 RAW bracketed capture. The sky was pretty featureless with thin overcast and smoke from the fire near Foresta but with some work I was able to bring out the texture you see.

” Feather Touch Paintings…” Amazing !!!

Amazing Feather Paintings

Many people have seen feathers as decorative items before. Today, ostrich, peacock and bird of paradise feathers can be seen in haute couture and in the costumes of indigenous peoples.

Alaskan-born and -bred artist Julie Thompson is an astounding exponent of this incredible art form. Known as feather art, this is the drawing or creation of images on feathers.

 

 
Light as a Feather, Beautiful as a Painting!
Julie, a self-taught wildlife artist for nearly 20 years, lives and works in the Pacific Northwest of Canada, close by the beautiful Puget Sound. She strives to make every feather painting as unique as the feathers themselves are, and believes that every feather has a kind of personality relating to the painting it bears.
Light as a Feather, Beautiful as a Painting!
Julie’s feather drawings have been well-received in galleries and exhibitions throughout the Pacific Northwest and are beginning to expand into other parts of the country. Successfully painting on feathers for 17 years now, Julie is finding that her work gets ever more public attention, to the extent that successful exhibitions in galleries throughout Canada have begun spreading out across the American continent as a whole.

Image of the Day….Titan… Saturn’s Moon !!!

Ten Years Ago, Huygens Probe Lands on Surface of Titan

Ten years ago, an explorer from Earth parachuted into the haze of an alien moon toward an uncertain fate. After a gentle descent lasting more than two hours, it landed with a thud on a frigid floodplain, surrounded by icy cobblestones. With this feat, the Huygens probe accomplished humanity’s first landing on a moon in the outer solar system. Huygens was safely on Titan, the largest moon of Saturn.

These images of Saturn’s moon Titan were taken on Jan. 14, 2005 by the Huygens probe at four different altitudes. The images are a flattened (Mercator) projection of the view from the descent imager/spectral radiometer on the probe as it landed on Titan’s surface.

The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency. NASA’s Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the mission for NASA’s Science Mission Directorate, Washington. JPL designed, developed and assembled the Cassini orbiter. NASA supplied two instruments on the Huygens probe, the Descent Imager/Spectral Radiometer and the Gas Chromatograph Mass Spectrometer.

Who Invented the Paper Clip … ?

The Invention of the Paperclip

The paperclip is today a ubiquitous item in offices and homes the world over. So who invented it?

One very popular false origin of the paperclip was that it was invented by Norwegian patent office manager, Johan Vaaler. He was even granted patents in Germany and the U.S. for a paperclip of similar design as the Gem style paperclip, which is the most commonly used paperclip today. However, Vaaler’s paperclip came after the Gem paperclip was already popular throughout Europe. His design was slightly different than the Gem paperclip in that it didn’t include the all too critical second loop that makes the Gem style much more functional. His paperclip had the papers inserted by lifting the outer wire slightly and pushing the papers into the clip such that the rest of the clip stood out from the paper at a 90 degree angle, which was necessary because of the lack of the critical second loop to allow the papers to be more or less embedded in the clip flatly.

This also made it so the papers wouldn’t be held together very well as they relied only on how bendable the wire used was to hold the papers. The Gem style paperclip, on the other hand, exploits the torsion principle to help bind papers together. Vaaler’s design was never manufactured or sold and his patents eventually expired.

Why Vaaler gets the credit in so many places, including in many encyclopedias and dictionaries after the 1950s, is largely thanks to a patent agency worker who was visiting Germany to register Norwegian patents in the 1920s. When he was doing so, he noticed Vaaler’s design for the paperclip and wrote an article stating Vaaler was the original creator of the paperclip.

This misinformation found its way into encyclopedias around the 1950s thanks to WWII. During WWII in Norway particularly, along with France and some other occupied countries, the paperclip became a symbol of unity for those rebelling against the Germans. It is not thought that the Norwegians did this because they thought a Norwegian had invented the paperclip, but rather because it simply signified being bound together and was useful as it wasn’t initially a banned symbol or item by the Germans and could be easily clipped to one’s clothing. Eventually, the Germans caught on and people were prohibited from wearing paperclips.

After the war, the fact that the Gem style paperclip had served as a symbol of unity resulted in interest in the origin of the paperclip, at which point the article written by the patent agency worker and the subsequent patent by Vaaler, who was now long dead, was discovered. It was overlooked, of course, that his design was different than the Gem style paperclip and apparently they didn’t bother checking that the Gem style paperclip had already been around by the time Vaaler patented his version of the paperclip. It made a good story though, particularly after the war and how the paperclip was used in Norway among other places, and so this false origin subsequently found its way into many encyclopedias.

The myth is so popular, in fact, that a Gem style, 23 foot tall paperclip was placed near a university in Oslo in 1989 to honor Vaaler, who in fact had nothing to do with the Gem style paperclip design. Further, a commemorative stamp was created honoring Vaaler that also depicted the Gem style paperclip, not Vaaler’s design.

Another false origin of the modern day paperclip often attributes it to Herbert Spencer, who was the man who came up with the term “survival of the fittest”. He claims in his autobiography that he invented a pin that bound papers together. This led to the false belief that he invented the paperclip. In fact, though, his drawing of his binding pin looked more like a cotter pin and, thus, held papers together more like Vaaler’s design. Unlike Vaaler’s design though, this cotter pin style clip wouldn’t stick out nearly as much and, thus, was a bit more functional.

So who really invented the paperclip as we know it today? It is thought to have first been made by the Gem Manufacturing Company in Britain around the 1870s and later introduced to the United States around the 1890s. This is also why the Swedish word for paperclip is “gem”. As for who within that company invented it, this isn’t known, as it was never patented nor did they realize at the time how historically significant that little invention would be, so nobody bothered to save the documentation of the invention.

Image of the Day….First Notable Solar Fire of 2015 …

 First Notable Solar Flare of 2015

The sun emitted a mid-level solar flare, peaking at 11:24 p.m. EST on Jan. 12, 2015. NASA’s Solar Dynamics Observatory, which watches the sun constantly, captured an image of the event. Solar flares are powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth’s atmosphere to physically affect humans on the ground, however — when intense enough — they can disturb the atmosphere in the layer where GPS and communications signals travel.

Planes Go ” Hybrid ” Electric…. !!!

 

An aircraft with a parallel hybrid engine – the first ever to be able to recharge its batteries in flight – has been successfully tested in the UK, an important early step towards cleaner, low-carbon air travel.

The world’s first hybrid-electric aircraft that can recharge while flying. 
Electric aircraft

A new hybrid-electric aircraft, the first ever to be able to recharge its batteries in flight, has just been tested in the UK, the University of Cambridge announced in a statement today.

The plane uses a “parallel hybrid-electric propulsion system,” where an electric motor works with a regular petrol motor to drive a propeller. It’s just been trialled at a test site in Northamptonshire.

According to Cambridge engineers, the plane uses 30% less fuel than a similar model that only uses a petrol engine. More importantly, the new design can also recharge its batteries during flight — something that’s never been achieved before.

“Although hybrid cars have been available for more than a decade, what’s been holding back the development of hybrid or fully-electric aircraft until now is battery technology,” project leader and Cambridge professor Paul Robertson said in a statement. “Until recently, they have been too heavy and didn’t have enough energy capacity. But with the advent of improved lithium-polymer batteries, similar to what you’d find in a laptop computer, hybrid aircraft — albeit at a small scale — are now starting to become viable.”

The plane uses its 4-stroke piston engine and electric motor during take off and climbing. But once in cruising mode, the electric motor switches to an electric generator in a similar way to a hybrid car. Once full height is reached, the generator mode can then recharge the batteries or be used in motor assist mode to minimise fuel consumption, the university said.

Here it is climbing after take off:

And here it is soaring over England’s patchwork fields:

The project is vital to combating the impact air travel has on the environment. The team notes that the Intergovernmental Panel on Climate Change estimates “aviation is responsible for around 2% of global man-made carbon dioxide emissions.”

The plane is a step “towards cleaner, low-carbon air travel,” but it’s not there yet. More research is still needed to prolong the flying time. “If all the engines and all the fuel in a modern jetliner were to be replaced by batteries, it would have a total flying time of roughly ten minutes,” the researchers point out.

Still, the Cambridge demonstrator model is a move toward creating the first fully-electric plane, which could one day be used commercially.

Coldest Place on Earth… Oymyakon , Russia…

It may look serene but the temperatures here can be seriously unbearable. Picture: Maarte

IT’S been named the coldest permanently inhabited place on Earth reaching a record low of minus 71.2 degrees Celsius in 1924.

The 500 or so residents of Oymyakon in Siberia live in one of the remotest places on Earth, just a few hundred kilometres from the Arctic Circle.

Wired reports that Oymyakon is a town full of extremes. It lies in complete darkness for 21 hours a day during winter yet daylight lasts for 21 hours in summer.

The nearest major city, Yakutsk, is a two day drive away, accessible only by road during winter when the conditions are too harsh for planes to land.

The ground remains permanently frozen meaning crops cannot grow so its population lives on a diet of reindeer and horse meat, raw frozen fish flesh and a local delicacy of frozen horse blood and macaroni.

Petrol stations in the main road stay open 24 hours a day should you get stuck.

If you’re brave enough to drive a car, it must be left in idle once out of a heated garage for fear it will freeze and never start again. And trips to the bathroom are just as unpleasant, its residents must use outhouses as the indoor plumbing too often freezes.

It becomes problematic when someone dies. The ground has to be warmed for days by a bonfire to be able to bury the dead. And the town’s only school has a policy to shut if the temperatures fall below -52 degrees Celsius.

Called the ‘Pole of Cold’, the name Oymyakon ironically means ‘unfrozen water’, thought to be a reference to the thermal springs that reindeer herders would visit until it became a permanent inhabited settlement.
