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

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.

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.

Entangling twisted
beams
"To Anton Zeilinger, Robert Fickler and
colleagues at the University of Vienna
for devising a new technique for
entangling photons using orbital angular
momentum."
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

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

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.
