SPANDAN VOLUME1,ISSUE2 QUARTERLY MARCH 2015 NEWSLETTER OF PHYSICAL SCIENCEss QUARTERLY NEWSLETTER OF PHYSICAL SCIENCE SRI SATHYA SAI COLLEGE FOR WOMEN BHOPAL NEWS LETTER ISSUSED FOR THE MONTH OF MARCH EDITORIAL BOARD:ADVISOR:-Dr.Archana Srivastava Student-Editor:Shivani Malviya (B.Sc.sem4) Shivani Sharma(B.Sc.sem4) Device that Helps You Understand Dog's Language The first version of this device appeared back in 2002. Now a new version of the Bowlingual comes into attention. The device is able to analyze a dog's bark and figure out its emotion.The inventor of this gadget is the toy-making company called Takara Tomy. The device will only be available for the dog lovers living in Japan.According to the company the Bowlingual is able to understand six of the dog's basic emotions. The firstmodel included a microphone attached to a dog's neck and a special handheld unit that was used to read the data and transmitted it from the microphone to display.The latest version features a more compact unit that includes a speech synthesizer. The latter audibly informs the person about the things their dog tries to say. this one shows all data on the screen of the handheld unit.Preeti S. Device that Produces Rainbows Rainbows are beautiful and that's it. Children enjoy watching these creations of nature, but one man thought that it would be better if people could see rainbows more often. This is why he has come up with a machine that creates rainbows.Artist Michael Jones McKean has been testing his device in parks where he shot small rainbows across the sky. Now he looks forward to developing a machine that would generate much larger rainbows with the help of reclaimed rainwater and sunlight.His studio is located at the Bemis Center forContemporary Arts in Omaha, Nebraska. -NAYANA DEVRE The discovery of a supermassive black hole from the early cosmos is set to rewrite physics, say scientists. An international team of astronomers detected a black hole 12 billion times the mass of our Sun, they reported. The black hole, which formed just 900 million years after the Big Bang, is the source of a powerful beam of bright material known as a quasar."When we found this supermassive black hole we got very excited because we had found something that we never thought we could find," says Dr Fuyan Bian of the Australian National University.

The orbital angular momentum of a corkscrewing light beam is a quantity that had been largely ignored until about 20 years ago. Today, however, physicists are busy dreaming up new applications for this "twisted light". They include Anton Zeilinger, Robert Fickler and colleagues, who have managed to entangle photons with orbital quantum numbers as high as 300 – more than 10 times greater than the previous record. As well as quantum computing, the new technique could lead to the entanglement of macroscopic objects and find applications in remote sensing -AMRITA MALVIYA SCIENTISTS OF THE MONTH:- Isamu Akasaki, Hiroshi Amano and Shuji Nakamura are rewarded for inventing a new energy efficient and environment-friendly light source – the blue light-emitting diode (LED). In the spirit of Alfred Nobel, the Prize awards an invention of greatest benefit to mankind; by using blue LEDs, white light can be created in a new way. With the advent of LED lamps we now have more long-lasting and more efficient alternatives to older light source -SHIVANI MALVIYA INSTERESTING FACTS..... The only rock that floats in water is pumice. Hot water freezes quicker than cold water. The Atlantic Ocean grows at about the same rate as your fingernails. The average ice berg weighs 20,000,000 tons. The bark of the redwood tree is fireproof. The Dead Sea is so dense with salt, you can easily float on it without drowning. Solar Impulse 2, #RTW Solar Airplane Solar Impulse is the only airplane of perpetual endurance, able to fly day and night on solar power, without a drop of fuel Solar Impulse is a Swiss long-range solar-powered aircraft project. It is led by Swiss psychiatrist and aeronaut Bertrand Piccard, who co-piloted the first balloon to circle the world non-stop, and Swiss businessman Andre Borschberg. The privately financed project hopes to achieve the first circumnavigation of the Earth by a piloted fixed-wing aircraft using only solar power. The first aircraft, bearing Swiss aircraft registration HB-SIA and often referred to as Solar Impulse 1, is a single-seat monoplane, capable of taking off under its own power, and designed to be able to remain airborne up to 36 hour. This aircraft conducted its first test flight in December 2009, and first flew an entire diurnal solar cycle, including nearly nine hours of night flying, in a 26-hour flight on 7–8 July 2010. Piccard and Borschberg completed successful solar-powered flights from Switzerland to Spain and Morocco in 2012 and conducted a multi-stage flight across the USA in 2013. Building on the experience of the prototype, a slightly larger follow-on design, designated HB-SIB and known as Solar Impulse 2, was built and first flown in 2014. In March 2015, it began a circumnavigation of the globe, leaving from Abu Dhabi in the United Arab Emirates and scheduled to return there five months later. Recently The Solar Impulse 2 Plane was landed at Sardar Vallabhbhai Patel International Air Port in Ahmedabad. o Quotes of the month:- OUR GUEST LECTURER – Dr. Shovit Bhattacharya Special Thanks To All The Teachers Of : Mathematics Department .
