Crow, (genus Corvus), any of various glossy black birds found in most parts of the world, with the exception of southern South America. Crows are generally smaller and not as thick-billed as ravens, which belong to the same genus. A large majority of the 40 or so Corvus species are known as crows, and the name has been applied to other, unrelated birds. Large crows measure about 0.5 metre (20 inches) long, with wingspans that can reach 1 metre (39 inches).

Crows feed chiefly on the ground, where they walk about purposefully. They are omnivores that enjoy meat and may even attack and kill young, weak animals. This habit makes them unpopular with farmers, as does the bird’s propensity to raid grain crops. Berries, insects, the eggs of other birds, and carrion are also eaten. Crows will make off with shreds of roadkill and store tidbits in trees, caching the meat like a leopard does for later consumption. Sometimes they bury seeds or store them in crevices in bark. They occasionally steal food from other animals, sometimes cooperating with other crows to raid food from otters, vultures, and water birds.

Prime minister Narendra Modi speaks about importance of blockchain

In a convocation ceremony held recently at Sher-e-Kashmir University Jammu Modi said, "India's youth can lead a revolutionary movement using Al and blockchain technologies.

Mr.Modi has talked about the importance of blockchain in the Agricultural field as the condition of Indian Farmers has gone from bad to worse with thousands of farmers committing suicide.

Indian states like Karnataka, Telangana, Andhra pradesh and Maharashtra are exploring the potential of blockchain, in e-governance.

Kerala has even established a 'Blockchain Academy' to explore its potential.

PM's focus on blockchain and its implementation could be the trump card for upcoming 2019 elections.

IMMERSIVE TECHNOLOGY

Immersive technology enables us to merge the physical and virtual words(and vice versa). Mixed realities are changing the way we shop, interact on social media and most importantly, how to tell stories. 

                

You all must have read or heard about Augmented reality, virtual reality, mixed reality but what about Extended reality?

Extended Reality (XR) encompasses all realities. It's an umbrella term that encompasses everything: 360-degree video, augmented, virtual, and mixed realities, and whatever other realities might be created in the future.

Platforms like Unity are embracing the term XR. Interestingly, the title of one of their top developers, Sarah Stumbo, is "XR evangelist".

XR has always been an acknowledged technology; it just didn't have a name. Now it's disrupting the news media. healthcare, film, retail, and marketing industries.

If God created the Universe, then who created God?

CHAPTER-1

GOD CREATED THE UNIVERSE 

Air pollution means the presence of chemicals or compounds in the air which lower the quality of the air or cause detrimental changes to the quality of life. Now air pollution is clear to you.

NOW LETS MOVE TO OUR TOPIC

CHAPTER-2

DOES THE UNIVERSE HAVE A BEGINING?

In this chapter,we talk about the BEGINING of this universe with the explanation of osciallating universe ideas. This chapter will help you to understand the begining and cause of this universe.

CHAPTER-3

DENIAL OF CAUSE AND EFFECT

Did you know some physicists assert that quantum mechanics violates this cause/effect principle and can produce something from nothing.So this chapter we will explain you DENIAL OF CAUSE AND EFFECT.

CHAPTER-4

WHO CREATED GOD?

This chapter is really interesting. In this chapter we will talk about the creation of god with the help of some scientific examples.

CHAPTER-5

WHAT MUST THE CAUSE OF THE UNIVERSE?

In this chapter, we will analysis the theories that can explain us the cause of the universe.

CHAPTER-6

TWO 'GREAT BEGININGS' WITHOUT ANY CAUSE

This is last chapter of this ebook. And this chapter is really interesting, in this chapter we will talk about TWO GREAT BEGINNINGS' of this universe that has no cause

Scientists created a clock so accurate that it measure space-time

Einstein in his general theory of relativity has said that space and time are not distinct unrelated things but they exists in 4 dimensional space time continuum.At our scale we feel our time is uniformly flowing but if the speed of the object increases it's time dilates.Time measurement is done using some oscillations like Earth's rotation or simple pendulum but atomic clocks use oscillations of atoms.



The new atomic clock created is based on the frequency of vibration of ytterbium atoms and it measures time with the accuracy of 10^-18 order.To measure such a high frequency lasers are used.This clocks are reproducible and due to thermal and electromagnetic shielding there is no other effect which can change our time.
 
                               

As predicted  by Einsein's theory of relativity, The stronger the pull of gravity, the slower the vibrations of atoms and the passing of time. This effectively means that the clocks are showing not simple time, but also their distance from a center of gravity. They're effectively measuring the space-time continuum.


New clocks could potentially be used to perfectly measure the Earth's shape,since gravity gets stronger as you get closer to Earth's core. We can also measure tiny difference in time due to variation of gravity on the surface of the earth.

AT LAST,WE JUST WANT TO SAY, The clocks' sensitivity to gravity also means in the theory that they could be used to detect the presence of dark matter is, but we know it distorts gravity, and so these clocks could potentially pick up on it.

Hyperspectral imaging sats

 India sucessfully launched its latest earth observation satellite HysiS, the data from which can be used in wide-ranging areas agriculture, forestry, soil survey, geology, coastal zone studies, inland water studies,environmental moinitoring and pollution detection from industries.

Normal satellites captures images in visible spectral region of electromagnetic spectrum but hyperspectral satellites can take images across wide range of  electromagnetic spectrum.

Hyperspectral sensors collect information as a set of 'images'. Each images represents a narrow wavelength range of the electromagnetic spectrum also known as a spectral band.

Images corresponding small wavelength bands are combined to form a three-dimensional hyperspectral data cube for processing and analysis, where x and y represent two spatial dimension of the scene, and lamda represnts the spectal dimension.

The primary mission of the HysIS, whose mission life is five years, is to study the earth's surface in vision, near infrared and shortwave infrared regions of the electromagnetic spectrum. It is the primary satellite of the PSLV-C43 mission, which is on its 45th flight. 

REDTACTON TECHNOLOGY

Redtacton Technology uses the surface of the human body as a transmission medium.

Our body is creating minute electric charges all the time. This electric field thus created is used for Redtacton technology to transmit and receive the signals.

As soon as the human body comes in contact with the Redtacton transceiver, the signals will start to be transmitted. When the contact is taken off, the transmission will also stop.

Thus, this method is completely different from other signal transmitting technologies like wireless and infrared. Thus, like LAn and WAN, a new network protocol called HAN(Human Area Network), is being configured.
