                 AMAZON APP STORE.

The Amazon Appstore for Android is an app store for the Android operating system operated by It was opened on March 22, 2011 and was made available in nearly 200 countries.[2] Developers are paid 70% of the list price of the app or in-app purchase.[3]
Initial releaseMarch 22, 2011
Stable release
15 / 26 November 2014; 3 years ago[1]
Development statusActive / 800,000+ apps
Operating systemAndroidBlackBerry 10
TypeSoftware updatedigital distribution

On September 28, 2011, Amazon launched the Kindle Fire tablet.[4] The tablet, designed for media consumption in the Amazon ecosystem, relies solely on the Amazon Appstore for its marketplace, eschewing Google Play. Alongside the tablet was a new design for the Amazon Appstore designed to better integrate with the tablet's user interface.
On June 18, 2014, BlackBerry announced an official relationship with Amazon, which includes access to the Amazon Appstore in BlackBerry 10.3.  FEATURES.
The Amazon Appstore included the "Free App of the Day" feature.[6] Every day, an application, frequently a game, was offered for free. On the launch day, this game was Angry Birds Rio (Ad-Free), in itself a promotional game.[7] On The European launch day the free app was Angry Birds (Ad-Free). The Free App of the Day feature made an exception to Amazon's payments, instead giving the developer none of the list price during the featured day.[8]
The store's "Test Drive" feature allowed users to try an application in their web browser by launching a virtual copy of Android in the Amazon EC2 cloud for half an hour.[9] The Test Drive service was decommissioned in 2015, Amazon saying that the service had been in decline, partly due to many apps not supporting the feature, and the increasing prevalence of the “free-to-play” business model making it obsolete.[10]
In May 2013, Amazon introduced Amazon Coins as a form of payment on the store.
When the Appstore for Android launched in March 2011 it had about 3,800 apps. In June 2014, the app store had seen significant growth since June 2013, tripling the app selection from 80,000 to 240,000.[11] As of June 2015, the app store has nearly 334,000 apps.

Honda has revealed a prototype for a motorcycle that can move without being controlled by the rider, and that won't fall over.
The self-stabilising technology, named Moto Riding Assist, was unveiled by Honda during a driverless demonstration at this year's Consumer Electronics Show (CES) in Las Vegas.
The Japanese company says that the technology could greatly reduce accidents in slow-moving traffic, as it lessens the possibility of falling over while the motorcycle is at rest.
Powered by an digital system, the technology disengages the handlebar from the front forks when the motorcycle is travelling at speeds below three miles-per-hour, allowing a computer to take control.
The system can also sense leaning. When it does, it swings the wheel to either side to counteract any tipping. It also adjusts the angles of the front forks, lowering the bike's centre of gravity to improve stability.
"This would be for those who want to relax a little bit and not stress out about falling over, if they're older or a little shorter in stature or the bike is heavier," explained Honda's Lee Edmunds during a demonstration. "This takes away that anxiety."
Although the motorbike is still in the prototype stage, Honda says it has the potential to cut road deaths and improve riding experience.
The technology mirror's that seen in BMW's latest concept motorcycle, which has an inability to fall over – claiming to make "accidents a thing of the past".

What is nano technology

Posted by Prateek Kumar
                    WHAT IS NANOTECHNOLOGY.
Nanotechnology is science, engineering, and technology conducted at the nanoscale, which is about 1 to 100 nanometers.
Physicist Richard Feynman, the father of nanotechnology.
Nanoscience and nanotechnology are the study and application of extremely small things and can be used across all the other science fields, such as chemistry, biology, physics, materials science, and engineering.
                     HOW IT STARTED.
The ideas and concepts behind nanoscience and nanotechnology started with a talk entitled “There’s Plenty of Room at the Bottom” by physicist Richard Feynman at an American Physical Society meeting at the California Institute of Technology (CalTech) on December 29, 1959, long before the term nanotechnology was used. In his talk, Feynman described a process in which scientists would be able to manipulate and control individual atoms and molecules. Over a decade later, in his explorations of ultraprecision machining, Professor Norio Taniguchi coined the term nanotechnology. It wasn't until 1981, with the development of the scanning tunneling microscope that could "see" individual atoms, that modern nanotechnology began.

It’s hard to imagine just how small nanotechnology is. One nanometer is a billionth of a meter, or 10-9 of a meter. Here are a few illustrative examples:
  • There are 25,400,000 nanometers in an inch
  • A sheet of newspaper is about 100,000 nanometers thick
  • On a comparative scale, if a marble were a nanometer, then one meter would be the size of the Earth
Nanoscience and nanotechnology involve the ability to see and to control individual atoms and molecules. Everything on Earth is made up of atoms—the food we eat, the clothes we wear, the buildings and houses we live in, and our own bodies.
But something as small as an atom is impossible to see with the naked eye. In fact, it’s impossible to see with the microscopes typically used in a high school science classes. The microscopes needed to see things at the nanoscale were invented relatively recently—about 30 years ago.
Just how small is “nano?” In the International System of Units, the prefix "nano" means one-billionth, or 10-9; therefore one nanometer is one-billionth of a meter. It’s difficult to imagine just how small that is, so here are some examples:
  • A sheet of paper is about 100,000 nanometers thick
  • A strand of human DNA  is 2.5 nanometers in diameter
  • There are 25,400,000 nanometers in one inch
  • A human hair is approximately 80,000- 100,000 nanometers wide
  • A single gold atom is about a third of a nanometer in diameter
  • On a comparative scale, if the diameter of a marble was one nanometer, then diameter of the Earth would be about one meter
  • One nanometer is about as long as your fingernail grows in one second
The illustration below has three visual examples of the size and the scale of nanotechnology, showing just how small things at the nanoscale actually are.

Beginning as early as the 1930s, scientists were able to see at the nanoscale using instruments such as the scanning electron microscope, the transmission electron microscope, and the field ion microscope. The most recent and notable developments in microscopy are the scanning tunneling microscope and the atomic force microscope.
The electron microscope, first developed by German engineers Ernst Ruska and Max Knoll in the 1930s, uses a particle beam of electrons to illuminate a specimen and create a highly magnified image. Electron microscopes yield much greater resolution than the older light microscopes; they can obtain magnifications of up to 1 million times, while the best light microscopes can magnify an image only about 1,500 times.
The scanning tunneling microscope (STM) is among a number of instruments that allows scientists to view and manipulate nanoscale particles, atoms, and small molecules. Its development earned its inventors, Gerd Binig and Heinrich Rohrer, the Nobel Prize in Physics in 1986.
Atomic force microscopes (AFMs) gather information by "feeling" the surface with a mechanical probe. Gerd Binig, along with Calvin Quate and Christoph Gerber, developed the first AFM in 1986.

These microscopes make use of tiny but exact movements to enable precise mechanical scanning.

How much moon far away from earth

Posted by Prateek Kumar
                MOON FAR AWAY FROM EARTH.


                 You might be surprised.

Don’t be fooled! They’re actually really far apart. The moon is an average of 238,855 miles (384,400 km) away. How far away is that? That’s 30 Earths.

                   Average distance?

   Why mention the average distance? Well, the    moon is not always the same distance away    from Earth. The orbit is not a perfect circle.

   When the moon is the farthest away, it’s        252,088 miles away. That’s almost 32 Earths.    When it's closest, the moon is 225,623 miles    away.

Electric generator

Posted by Prateek Kumar
                 AN ELECTRIC GENERATOR.

An electric generator converts mechanical energy into electrical energy.
The principle behind the electric motor is based on Fleming’s right hand rule.
when a coil of insulated copper wire is forced to rotate inside a magnetic field then electric current is induced. The following figure shows circuit diagram of a simple AC generator. If axle X is rotated clockwise, then the length PQ moves upwards and the length RS moves downwards.
Since the lengths PQ and RS are moving in a magnetic field, a current will be induced due to electromagnetic induction. Length PQ is moving upwards and the magnetic field acts from left to right. Hence, according to Fleming’s right hand rule, the direction of induced current will be from P to Q. Similarly, the direction of induced current in the length RS will be from R to S. The direction of current in the coil is PQRS. Hence, the galvanometer shows a deflection in a particular direction. After half a rotation, length PQ starts moving down whereas length RS starts moving upward. The direction of the induced current in the coil gets reversed as SRQP. As the direction of current gets reversed after each half rotation, the produced current is called an alternating current (AC). To get a unidirectional current, instead of two slip rings, two split rings are used, as shown in the following figure. In this arrangement, brush A always remains in contact with the length of the coil that is moving up whereas brush B always remains in contact with the length that is moving down. The split rings C and D act as a commutator.

The direction of current induced in the coil will be PQRS for the first half and SRQP in the second half of the rotation. Therefore a unidirectional current is produced from the generator called DC generator
