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.

Message For the Day… ” Develop Self Confidence and Have Firm Faith in God…”

Your life may be compared to a stalk of sugar cane. Like the cane, which is hard and has many knots, life is full of difficulties. But these difficulties must be overcome to enjoy the bliss of the Divine, just as the sugarcane has to be crushed and its juice converted into cane-sugar (jaggery) to enjoy the permanent sweetness. Enduring bliss can be got only by overcoming trials and tribulations. Gold cannot be made into an attractive jewel without it being subjected to the process of melting in a crucible and being beaten into the required shape. When I address devotees as, ‘golden one (Bangaru)’ or Divine Embodiments of Love, I really mean it! You must go through the vicissitudes of life with forbearance and become attractive jewels. You should not allow yourselves to be overwhelmed by difficulties. Develop self-confidence and have firm faith in God.

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:

Flight



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.

QATAR airways is carrying out tests to become the first airline in the world to install an automatic tracking system that would replace the current radar system.

Chief Executive Officer Akbar Al Baker told a press conference in Doha that the technology was being tested ahead of a fleet wide roll out.

“Once this has been proven and all the bugs have been cleared then Qatar Airways will, I hope, be the first airliner to introduce this in all our planes,” he told reporters.

In response to worldwide pressure for tighter airline monitoring after the disappearance of Malaysia Airlines flight MH370, the new system will stream flight data from a planes black box directly to an airline’s operation centre on the ground in real time.

Reported in Bloomberg, it is part of an aviation safety overhaul as the industry comes under scruity for being unable to explain the mysterious fate of MH370.

The International Air Transport Association (IATA) set up an expert task force in June 2014 to review current tracking methods and highlighted three areas of concern. These were installing tamper proofing airline tracking, tracking to one nautical mile or better and giving airlines one year to implement the recommended new system.

The IATA however has come under fire from some airlines who say adopting these new criteria within a year is unreasonable. The International Civil Aviation Organization, a United Nations aviation regulator, has instead proposed that commercial planes be required to report their position every 15 minutes.

Qatar’s decision to install this new type of tracking means that its planes will be automatically tracked from takeoff to landing without control from pilots, removing any issues of tampering and providing real-time aircraft monitoring.

Money lessons from Makar Sankranti ….!!!

Let’s take you on a fun journey on kites and Sankranti traditions and guess what? You can learn a thing or two about financial planning from it as well.

Makar Sankranti

Come January 14 and the Indian skies will break into a riot of colours, as people celebrate Makar Sankranti. Kites of different shapes, sizes, colours and texture will vie in sky with each other to make a place for themselves and entangle in a pursuit to outdo the rest. As you are busy preparing for this festival of kites and friendly combat, have you really thought about its significance, and why kites are flown on Sankranti?

Makar Sankranti (Uttarayan or Pongal or Poush Sankranti as it is called in other parts of India) coincides with the day the Sun leaves the tropic of Cancer to move towards the tropic of Capricorn (called Makar in India). It is a day of great jubilation for farmers as it marks the end of the biting winters and the beginning of the new harvesting season. This day is therefore celebrated as a Thanksgiving for ending the harsh winters and a bountiful harvest.

Significance of flying kites on Sankranti

Sankranti has a philosophical significance in India as well. The word Sankranti literally means ‘movement’, and it is the day for the human race to realise and be thankful for movement. If there was to be no movement within and without our bodies, we would all be dead! But just like yin and yang in China, the concept of movement must be contrasted and appreciated against the stillness. Therefore, when we fly kites in the lap of the still skies, it is a reiteration of our thankfulness for this very movement!

Indian traditions are also rooted deeply in science and so is the tradition of kite flying on Sankranti. When we fly kites on Sankranti, we expose ourselves to the rays of the Sun. On this day when the Sun begins its journey towards the other hemisphere, it is expected to be benevolent and emanate rays that have medicinal benefits.

During the winters our bodies are usually infected with cold and other infections which are eradicated by the direct exposure to the Sun’s rays on this particular day.

Makar Sankranti traditions:

  • In Maharashtra, the ‘Til Gul’ ( a sweet made of sesame seeds and jaggery) are prepared in homes to mark the harvest of the first sugarcane crop of the year (out of which jaggery is made).
  • In Gujarat Makar Sankranti is referred to as Uttarayan, and kites are flown to wake the Gods from their winter slumber and bless farmers’ harvests.
  • In West Bengal this festival is referred to as ‘Poush Sankranti’ and is celebrated as a harvest festival where a variety of sweets such as Pithey, Puli, Patisapta are made with freshly harvested rice flour and jaggery made out of date palms.
  • In Uttar Pradesh it is believed that taking a holy dip in the Ganges on this day provides ‘Moksha’ or salvation from sins.
  • Makar Sankranti is referred to as Pongal in Tamil Nadu and other South Indian states, where it is celebrated as a three day festival which include lot of festivities.

Some financial lessons you can learn Makar Sankranti:

Get set for a flight:

Financial planning is not just about making a plan and keeping it static. You need to keep reviewing it and armed with proper resources and research of the markets you need to seize the opportunities that arise in the economic environment to enhance your portfolio. This is akin to kite flying where you need to customise a kite as per your abilities, have the perfect manjha or string and set it to flight to soar above the rest when the wind is in your favour.

Keep your eyes on your kite:

When you are flying a kite, you cannot for a moment be careless and lose sight of how or in which direction your kite is flying. Similarly, in financial planning you have to be vigilant of the course that your investments are taking and review your investments to see that your financial goals both short term and long term are being met.

Be flexible

While flying kites people shout out ‘dheel de!’ to their companions. It means when you are in the midst of a strong gust of wind you have to let go the string off and adapt to the situation. Similarly, when it comes to an investment climate, things are not always perfect. You have to be patient and sometimes bear some temporary losses, but never lose sight of your vision of meeting your financial goals.

So now armed with this new found knowledge of Makar Sankranti, go ahead and fly those kites with new found fervour! Kai Po Che!
