We know the term “city “that is on the ground,but there is another term when associated with the term city gives of a thrilling vibes and piques the curiosity of people and the term is “UNDERGROUND”
“Underground city” it is a city which is literally as the name says underneath the ground. So today we are going to discuss about a city called “Derinkuyu”.
From viator.com
It is an ancient multi-levelunderground city in Turkey.
It is the deepest excavated underground city in Cappadocia and a stunning wonder.
The city is said extends to a depth of 200 feet and could have sheltered as many as 20,000 people together.
Derinkuyu city is famous for its capacity to hold thousands of families that is one of the highest among many underground cities that were found.
It’s said that this city dwelling not only could hold thousands of people, but also contained everything an entire population would need to survive any crises.
There are numerous subterranean dwellings and secret tunnel passages that were used as shelters.
From:Getyourguide
The underground city at Derinkuyu could be closed from the inside with large stone doors enhancing the security measures up a notch and each floor could be closed off separately.
It had aminities such as wine and oil presses, stables, cellars, storage rooms, refectories, and chapels.
On the second floor is a spacious room with a barrel-vaulted ceilings ,and rooms were used as a religious school and for study purposes.
There is a series of vertical staircases between the 3rd and 4 th floor leading to the church located at lowest level.

There is a large 55-metre ventilation shaft a which seemed to provide water to both the villagers above and, if the outside world was not accessible, to those in hiding.
What fascinates me is how did they build this city without having any access to the technology and designed it beautifully and they took all kinds off possibilities into account making a city which is anytime ready to face any kind of problem.
It is said to be one of the top most tourist destinations in Turkey. You can also visit this by booking tickets in a trusted website.
Human intelligence is the intellectual capability of humans, which is marked by complex cognitive feats and high levels of motivation and self-awareness.Through intelligence, humans possess the cognitive abilities to learn, form concepts, understand, apply logic, and reason, including the capacities to recognize patterns, plan, innovate, solve problems, make decisions, retain information, and use language to communicate. There are conflicting ideas about how intelligence is measured, ranging from the idea that intelligence is fixed upon birth, or that it is malleable and can change depending on an individual’s mindset and efforts.Several subcategories of intelligence, such as emotional intelligence or social intelligence, are heavily debated as to whether they are traditional forms of intelligence.They are generally thought to be distinct processes that occur, though there is speculation that they tie into traditional intelligence more than previously suspected.
Various definitions of intelligence tend to converge around similar notions designed to capture the essence of this psychological factor. Jensennotes Carl Bereiter’s definition of intelligence: “what you use when you don’t know what to do” (p 111). After their extensive survey, Snyderman and Rothmanunderscored reasoning, problem solving, and learning as crucial for intelligence. The “mainstream science on intelligence” report coordinated by Gottfredsonhighlights reasoning, planning, solving problems, thinking abstractly, comprehending complex ideas, learning quickly, and learning from experience. The American Psychological Association (APA) report on intelligence acknowledges that “individuals differ from one another in their ability to understand complex ideas, to adapt effectively to the environment, to learn from experience, to engage in various forms of reasoning, to overcome obstacles by taking thought.
For more than a century, psychologists have developed hundreds of tests for the standardized measurement of intelligence with varying degrees of reliability and validityThe resulting measures allowed for the organization of taxonomies identifying minor and major cognitive abilities. J. B. Carroll,for example, proposed a threestratum theory of intelligence after the extensive reanalysis of more than 400 datasets with thousands of subjects from almost 20 different countries around the world.shows a simplified depiction of the taxonomy of cognitive abilities.
This survey of factor analytic studies supports the view that intelligence has a hierarchical structure (ie, like a pyramid). There is strong evidence for a factor representing general intelligence (g) located at the apex of the hierarchy (stratum III). This g factor provides an index of the level of difficulty that an individual can handle in performing induction, reasoning, visualization, or language comprehension tests. At a lower order in the hierarchy (stratum II), several broad ability factors are distinguished: fluid intelligence, crystallized intelligence, general memory, visual perception, auditory perception, retrieval, or cognitive speed. Lastly, stratum I is based on specific abilities, such as induction, lexical knowledge, associative memory, spatial relations, general sound discrimination, or ideational fluency.
Artificial Intelligence:-
INTRODUCTION:-
Artificial intelligence (AI), the ability of a digital computer or computer-controlled robot to perform tasks commonly associated with intelligent beings. The term is frequently applied to the project of developing systems endowed with the intellectual processes characteristic of humans, such as the ability to reason, discover meaning, generalize, or learn from past experience. Since the development of the digital computer in the 1940s, it has been demonstrated that computers can be programmed to carry out very complex tasks—as, for example, discovering proofs for mathematical theorems or playing chess—with great proficiency. Still, despite continuing advances in computer processing speed and memory capacity, there are as yet no programs that can match human flexibility over wider domains or in tasks requiring much everyday knowledge. On the other hand, some programs have attained the performance levels of human experts and professionals in performing certain specific tasks, so that artificial intelligence in this limited sense is found in applications as diverse as medical diagnosis, computer search engines, and voice or handwriting recognition.
Today, Artificial Intelligence is a very popular subject that is widely discussed in the technology and business circles. Many experts and industry analysts argue that AI or machine learning is the future – but if we look around, we are convinced that it’s not the future – it is the present.With the advancement in technology, we are already connected to AI in one way or the other – whether it is Siri, Watson or Alexa. Yes, the technology is in its initial phase and more and more companies are investing resources in machine learning, indicating a robust growth in AI products and apps in the near future.
The following statistics will give you an idea of growth!
– In 2014, more than $300 million was invested in AI startups, showing an increase of 300%, compared to the previous year (Bloomberg)
– By 2018, 6 billion connected devices will proactively ask for support. (Gartner)
– By the end of 2018, “customer digital assistants” will recognize customers by face and voice across channels and partners (Gartner)
– Artificial intelligence will replace 16% of American jobs by the end of the decade (Forrester)
– 15% of Apple phone owners’ users use Siri’s voice recognition capabilities. (BGR)
Unlike general perception, artificial intelligence is not limited to just IT or technology industry; instead, it is being extensively used in other areas such as medical, business, education, law, and manufacturing.

Difference Between Artificial Intelligence and Human Intelligence
Artificial Intelligence: Artificial Intelligence is based on the human insights that can be decided in a way that can machine can effortlessly actualize the tasks, from the basic to those that are indeed more complex. The reason for manufactured insights is learning, problem-solving, reasoning, and perception. This term may be connected to any machines which show related to a human intellect such as examination and decision-making and increments the efficiency. AI covers assignments like robotics, control systems, face recognition, scheduling, data mining, and numerous others.
Human Intelligence: Human intelligence or the behaviour of the human being has come to past experiences and the doings based upon situation, environment. And it is completely based upon the ability to change his/her own surroundings through knowledge which we gained. It gives diverse sorts of information. It can provide data on things related to the particular aptitude and knowledge, which can be another human subject, or, within the case of locators and spies, diplomatic data to which they had to get to. So, after concluding all it can give data on interpersonal connections and arrange of interest.
Below is a table of differences between Artificial intelligence and Human intelligence:
Feature
Artificial Intelligence
Human Intelligence
Emergence
AI is an advancement made by human insights; its early improvement is credited to Norbert Weiner who theorized on criticism mechanisms.
On the other hand, human creatures are made with the intrinsic capacity to think, reason, review, etc.
Pace/Rate of AI and human
As compared to people, computers can handle more data at a speedier rate. For occurrence, in the event that the human intellect can solve a math problem in 5 minutes, AI can solve 10 problems in a minute.
In terms of speed human cannot beat the speed of AI, or, machines.
Decision Making
AI is profoundly objective in choice making because it analyzes based on absolutely accumulated data.
Human’s choices may be affected by subjective components which are not based on figures alone.
Perfection
AI frequently produces precise comes about because it capacities based on a set of modified rules.
For human insights, there’s more often than not a room for “human error” as certain subtle elements may be missed at one point or the other.
Energy Consumption
Modern computer generally uses 2 watts energy.
On the other hand, human brains uses about 25 watts
Modification of AI and Human
AI takes much more time to adjust to unused changes.
Human insights can be adaptable in reaction to the changes to its environment. This makes individuals able to memorize and ace different skills.
Versatility
AI can as it were perform less assignments at the same time as a framework can as it were learn duties one at a time.
The human judgment skills underpins multitasking as prove by differing and concurrent roles.
Social Networking
AI has not aced the capacity to choose up on related social and enthusiastic cues.
On the other hand, as social creatures, people are much way better at social interaction since they can prepare theoretical data, have self-awareness, and are delicate to others’ feelings.
Size range – 0.21nm(0.008inch)-5cm(2inch) in length.
Usually 4 membranous wings
Forewing and hindwing are held together by small hook.
Hind pair smaller than front pair
Complete metamorphosis (Holometabolous).
Mouthparts modified for chewing and sucking
In some form especially bees, certain Mouthparts (labium and maxillae) form a structure for sucking liquid food.
Antennae usually with 10 or more segment.
Larvae usually maggot like(i.e. Leg less)
Large compound eyes, usually 3 simple eyes(ocelli) present.
Females typically have a special ovipositor for inserting eggs into host or places that are otherwise inaccessible.
Most have constriction between the first 2 segment of the abdomen which is known as a wasp waist.
Worldwide there are over 100,000 species included in the Hymenoptera.
In Australia, there are about 1275 ant, 10,000 wasp, 2000 bee and 176 sawfly species.
Habitat
Found in all terrestrial habitat throughout Australia.
May occur in soil, leaf litter and range of vegetation types especially flowers.
Life Cycle
Some female produce young one without mating, while other can store sperms and spread out their egg laying to coincide with available food.
Most species lay their egg to the host plant or paralysed food sources they have gathered into specially constructed nest.
The Larvae will moult several times before they pupate.
Development may range from a few weeks for some parasitoid to much longer in social species.
Feeding Habit
Feed on a wide range of foods depending on the species.
Adult wasp mostly feed on nectar and honeydew.
Some species are predator or parasites and spend their time searching out invertebrate hosts to lay their eggs on.
Some are predator, scavenger, omnivores, seedeaters, fungus feeders or honeydew feeders
Suborder of hymenoptera :
1) Symphyta(sawflies and horntails)
2)Apocrita(ants, bees and wasps)
Symphyta :(sawflies)
Most primitive Hymenoptera
Have a broad junction between thorax and abdomen.
Body has no waist.
Paraphyletic group
Females have a saw-like egg laying device for cutting slits in plants into which eggs are laid.
Larvae are caterpillar-like and feed on outside and inside of plant tissue.
There are one or two parasitic families
lack of constriction at the base of the abdomen
fly-like appearance and more extensive wing venation.
They are often confused with lepidopteron larvae but it include–six or more pair of abdominal prolegs(which lack chrochet ), one lateral ocellus on each side of head.
Apocrita :(wasps,bees,ants)
The body has a distinct waist.
The first segment of the abdomen is incorporated into the thorax. A narrow region called the petiole joins this to the rest of the abdomen, called the gaster.
Characterized by Larvae that feed on other Arthropods.
The larvae are maggotlike.
Have narrow junction between thorax and abdomen.
Contain largest no. of species.
Node is usually present.
Further divided into:- Terebrantia(parasitica) which use their ovipositor for egg laying and the Aculeata, which have the ovipositor modified as a sting.
Talking about our most crucial resource “Water”, our rivers, lakes, seas are flooding with chemicals, waste, plastic, and other pollutants. Every living being’s life has become nothing but a threat. Yet we trash water anyway. A British poet named W.H Auden once said “Thousands have lived without love, not one without water.” Polluted water takes away more life than any war/form of violence. With access to less than 1℅ of freshwater resources, it is estimated that by 2050 demand for freshwater will increase by 1/3 than it is today.
In this article, you’ll know:-

What is water pollution?
Water pollution is caused when water bodies are contaminated with chemicals, wastes, or microorganisms, that end up turning water bodies toxic to humans and the environment.
Causes of Water Pollution:-
Water is a Universal Solvent, and it can dissolve more substances than any other liquid on earth. That’s why water is easily polluted. Toxic Substances from factories, farms, and towns mix with it and make it polluted.
I) Groundwater Pollution- Groundwater gets polluted when pollutants like pesticides, fertilizer runoff, waste are leached from the trash yard and septic systems.
II) Surface Water Pollution- Surface water gets polluted by fertilizer runoff, farm waste, municipal and industrial waste, dumping garbage directly, etc.
III) Ocean water Pollution- Chemicals, nutrients, and many toxic substances from farms, industries, cities are carried by streams and rivers to the sea. Hence, ocean water gets polluted. It is also polluted because of oil spills and leaks.
IV) Radioactive Pollution- Radio Active wastes are generated by uranium mining, nuclear power plants, and by universities and hospitals using radioactive material for research. Unknowingly released or improper disposal of these pollutants can threaten groundwater, surface water, and marine resources.
What are the ways to prevent water pollution?
The ways by which one can prevent water pollution are:-
I) Reduce, reuse and recycle plastic.
II) Maintenance of vehicles(especially checking oil leakage or coolant leakage.
III) Proper disposal of chemicals, factory waste, oils, and non-biodegradable substance.
IV) By avoiding the usage of pesticides and herbicides.
Disability etiquette is a set of guidelines dealing specifically with how to approach persons with disabilities . Before knowing about disability etiquettes , it is essential to understand certain basic things such as if someone has a disability don’t assume he/she needs help . In fact , adults with disabilities wants to be treated as an independent persons , So offer help only if the person with disability seems to need it . Physical contact should be avoided . Always speak directly to the person with a disability , not to his/her friend . Persons with disabilities are the best judge of what they can or can’t do .
General Disability Etiquettes
The general disability etiquettes are stated below :
Always put the person first , i.e., say ‘person with disability ‘ rather than ‘disabled person’ . Always avoid the outdated words like handicapped , retarded , physically challenged or differently – abled . For example , refer to ‘person who are blind ‘ rather than ‘ blind person ‘.
In case of introduction to a person with a disability , it is appropriate to shake hands .
When you meet a person with a visual impairment , always identify yourself and others who may be with you .
Leaning or hanging on a person ‘s wheelchair should always be avoided because such act is generally considered annoying . In fact , the chair is the part of the personal body space of the person who uses it.
Always listen carefully as well as attentively when you are having conversations with a person who has difficulty in speaking . Have patience and wait for the person to finish rather than correcting or speaking for that person . Generally , ask short questions that require short time .
When talking with a person who is on a wheelchair or person who uses crutches , keep yourself at eye level in front of the person to facilitate the talk .
To get the attention of a person who is deaf or having hearing impairment , tap the person on the shoulder or wave your hand . You should look directly at the person and speak clearly .
Never patronize person who use wheelchairs by patting them on the head or shoulder .
Always introduce yourself to persons who are blind using your name .
Always avoid asking personal questions to an individual who is differently-abled .
Always give additional time to a person with any disability to do or to say something .
Always have conversation at a normal tone of voice . Don’t talk in high pitch to such individuals .
Don’t pretend to understand if you are facing problem in doing so .
If you need to leave a person who is blind , inform him that you are leaving and ask him if he needs anything before you leave .
Social media is a very web based application that gives information publishing and sharing connecting to a community and searching within the community social media interactive technology that allow the creation or other forms of expressions via virtual well being. Community and network in social media are interactive web based application social media helps to develop online social network by connecting a user’s profile with those of other individuals or groups.

Social media can help to improve individual sense of connected uses with real or online community and can be an effective communication tool for corporations entrepreneur nonprofit organisation advocacy group political parties and government. An important feature of social media is digital media data compression due to the impractically high memory and bandwidth requirements of an comprised media. Observes I’ve also seen that there has been a race in social movements using social media as a tool for communicating and organising in time of political unrest some social media site have the potential for content posted there to spread viral over social networks. In some cases posts containing popular content for fast breaking news have been rapidly shade and reshade by use number of users non profit organisation and activist may have similar interest in posting content on social media sites with the aim of going viral. According to statistics it is estimated that in 2020 there are around 3.6 billion people using social media around the globe social media is important because it allows you to reach nurture and engage with your target audience no matter their location social media helps you reach large audience as it’s a large or great opportunity for your business to reach a large pool of people that are interested in your product or service.

Jeff Bezos will fly on the first passenger flight of his space company Blue Origin, which the company plans to launch on July 20, the billionaire announced Monday.
“I want to go on this flight because it’s the thing I’ve wanted to do all my life,” Bezos said in a video posted to his Instagram.
Bezos’ brother Mark will join him, as will the winner of an auction being held for one of the seats. The highest bid stands at $2.8 million as of Monday morning, five days before the auction closes.
“I wasn’t even expecting him to say that he was going to be on the first flight,” Mark Bezos said in the video. “What a remarkable opportunity, not only to have this adventure but to do it with my best friend.”
Jeff Bezos takes a look at the New Shepard rocket booster on the landing pad after a successful NS-15 flight and landing in April 2021.
New Shepard is designed to carry up to six people on a ride past the edge of space, with the capsules on previous test flights reaching an altitude of more than 340,000 feet (more than 100 kilometers). The capsule has massive windows to give passengers a view, spending a few minutes in zero gravity before returning to Earth.
Jeff Bezos opens the hatch of the New Shepard capsule after a test flight in April 2021.Blue Origin
The rocket launches vertically, with the booster detaching and returning to land at a concrete pad nearby. The capsule’s return is slowed by a set of parachutes, before softly landing in the desert.
“To see the Earth from space, it changes you,” the Amazon CEO said. “It’s an adventure; it’s a big deal for me.”
For the past few years, scientists have been studying a dust cloud near the centre of our Milky Way Galaxy. If there is a God out there, it seems that he decided to get creative – this dust cloud , named Sagittarius B2, smells of rum and tastes like raspberries… This gas cloud consists largely of ethyl formate. This large cloud is said to contain a billion , billion, billion liters of the stuff, which would be great , if it wasn’t rendered undrinkable by pesky particles like propyl cyanide. The creation and distribution of these more complex molecules is still a mystery to scientists.
How could it be possible that when the time gets worse we often ignore the vulnerable?

We are living in the world , where no one can intrude . A life , where you can’t touch the one you want . A life, where one has to stay away from his own . A life , where no one can go in one’s home . Yes , it’s a life we are living ‘ A life of a LOG’ .
Coronavirus , I believe it’s not a new word in your dictionary . This eleven letter word creating a massive destruction all over the world . I know you are well aware but the real question is , are you following the protocols properly?
Firstly let’s get some knowledge about coronavirus.
The origin .
The recent outbreak began in Wuhan, a city in the Hubei province of China. Reports of the first COVID-19 cases started in December 2019.
Coronaviruses are common in certain species of animals, such as cattle and camels. Although the transmission of coronaviruses from animals to humans is rareTrusted Source, this new strain likely came from bats, though one study suggests pangolins may be the origin.
However, it remains unclear exactly how the virus first spread to humans.
Some reports trace the earliest cases back to a seafood and animal market in Wuhan. It may have been from here that SARS-CoV-2 started to spread to humans.
Coronaviruses are a group of viruses that can cause disease in both animals and humans. The severe acute respiratory syndrome (SARS) virus strain known as SARS-CoV is an example of a coronavirus. SARS spread rapidly in 2002–2003.
The new strain of coronavirus is called severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The virus causes coronavirus disease 19 (COVID-19).
Around 80%Trusted Source of people with COVID-19 recover without specialist treatment. These people may experience mild, flu-like symptoms. However, 1 in 6 peopleTrusted Source may experience severe symptoms, such as trouble breathing.
The new coronavirus has spread rapidly in many parts of the world. On March 11, 2020, the World Health Organization (WHO)Trusted Source declared COVID-19 a pandemic. A pandemic occurs when a disease that people are not immune to spreads across large regions.
It’s okay take a deep breath . Yes, it’s a lot to take in but we all know how china played with the whole world .
The protocols.
Wear masks ,
Wash hands ,
Use sanitizers ,
Social distancing , etc,.
Is it important to follow protocols ?
You say NO , I say ‘if you want to die you can easily ignore the protocols ’ . Well I don’t want to die , I have my whole 20s , 30s and so on…… .
According to the survey, people have been moving around freely, meeting different social groups and attending gatherings, going to malls and markets. This indicates that a pandemic fatigue has set in after after a year of restrictions on movement, social distancing and strict mask wearing norms.
Well , if you are saying this is what following protocols is than I am happy to stay home rather than chilling around like a monkey . Like really , a monkey also has a common sense that when to do chilling and when to fight for himself . What we are doing is putting masks in our pocket to showcase the world that I have one . Haha it’s kinda funny .
We long to return to normal, but **normal led to this**. To avert the future pandemics we know are coming, we MUST grapple with all the ways normal failed us. We have to build something better. I hope this piece, in showing what went wrong, helps.
Astrophysics is a branch of space science that applies the laws of physics and chemistry to explain the birth, life and death of stars, planets, galaxies, nebulae and other objects in the universe. It has two sibling sciences, astronomy and cosmology, and the lines between them blur.
In the most rigid sense: Astronomy measures positions, luminosities, motions and other characteristics Astrophysics creates physical theories of small to medium-size structures in the universe Cosmology does this for the largest structures, and the universe as a whole.
In practice, the three professions form a tight-knit family. Ask for the position of a nebula or what kind of light it emits, and the astronomer might answer first. Ask what the nebula is made of and how it formed and the astrophysicist will pipe up. Ask how the data fit with the formation of the universe, and the cosmologist would probably jump in. But watch out — for any of these questions, two or three may start talking at once! Goals of astrophysics Astrophysicists seek to understand the universe and our place in it. At NASA, the goals of astrophysics are “to discover how the universe works, explore how it began and evolved, and search for life on planets around other stars,” according NASA’s website.
NASA states that those goals produce three broad questions:
How does the universe work?
How did we get here?
Are we alone?
It began with Newton
While astronomy is one of the oldest sciences, theoretical astrophysics began with Isaac Newton. Prior to Newton, astronomers described the motions of heavenly bodies using complex mathematical models without a physical basis. Newton showed that a single theory simultaneously explains the orbits of moons and planets in space and the trajectory of a cannonball on Earth. This added to the body of evidence for the (then) startling conclusion that the heavens and Earth are subject to the same physical laws.
Perhaps what most completely separated Newton’s model from previous ones is that it is predictive as well as descriptive. Based on aberrations in the orbit of Uranus, astronomers predicted the position of a new planet, which was then observed and named Neptune. Being predictive as well as descriptive is the sign of a mature science, and astrophysics is in this category.
Milestones in astrophysics
Because the only way we interact with distant objects is by observing the radiation they emit, much of astrophysics has to do with deducing theories that explain the mechanisms that produce this radiation, and provide ideas for how to extract the most information from it. The first ideas about the nature of stars emerged in the mid-19th century from the blossoming science of spectral analysis, which means observing the specific frequencies of light that particular substances absorb and emit when heated. Spectral analysis remains essential to the triumvirate of space sciences, both guiding and testing new theories.
Early spectroscopy provided the first evidence that stars contain substances also present on Earth. Spectroscopy revealed that some nebulae are purely gaseous, while some contain stars. This later helped cement the idea that some nebulae were not nebulae at all — they were other galaxies!
In the early 1920s, Cecilia Payne discovered, using spectroscopy, that stars are predominantly hydrogen (at least until their old age). The spectra of stars also allowed astrophysicists to determine the speed at which they move toward or away from Earth. Just like the sound a vehicle emits is different moving toward us or away from us, because of the Doppler shift, the spectra of stars will change in the same way. In the 1930s, by combining the Doppler shift and Einstein’s theory of general relativity, Edwin Hubble provided solid evidence that the universe is expanding. This is also predicted by Einstein’s theory, and together form the basis of the Big Bang Theory.
Also in the mid-19th century, the physicists Lord Kelvin (William Thomson) and Gustav Von Helmholtz speculated that gravitational collapse could power the sun, but eventually realized that energy produced this way would only last 100,000 years. Fifty years later, Einstein’s famous E=mc2 equation gave astrophysicists the first clue to what the true source of energy might be (although it turns out that gravitational collapse does play an important role). As nuclear physics, quantum mechanics and particle physics grew in the first half of the 20th century, it became possible to formulate theories for how nuclear fusion could power stars. These theories describe how stars form, live and die, and successfully explain the observed distribution of types of stars, their spectra, luminosities, ages and other features.
Astrophysics is the physics of stars and other distant bodies in the universe, but it also hits close to home. According to the Big Bang Theory, the first stars were almost entirely hydrogen. The nuclear fusion process that energizes them smashes together hydrogen atoms to form the heavier element helium. In 1957, the husband-and-wife astronomer team of Geoffrey and Margaret Burbidge, along with physicists William Alfred Fowler and Fred Hoyle, showed how, as stars age, they produce heavier and heavier elements, which they pass on to later generations of stars in ever-greater quantities. It is only in the final stages of the lives of more recent stars that the elements making up the Earth, such as iron (32.1 percent), oxygen (30.1 percent), silicon (15.1 percent), are produced. Another of these elements is carbon, which together with oxygen, make up the bulk of the mass of all living things, including us. Thus, astrophysics tells us that, while we are not all stars, we are all stardust.
Astrophysics as a career

Becoming an astrophysicist requires years of observation, training and work. But you can start becoming involved in a small way even in elementary and high school, by joining astronomy clubs, attending local astronomy events, taking free online courses in astronomy and astrophysics, and keeping up with news in the field on a website such as Space.com.
In college, students should aim to (eventually) complete a doctorate in astrophysics, and then take on a post-doctoral position in astrophysics. Astrophysicists can work for the government, university labs and, occasionally, private organizations.
Take math and science classes all through high school. Make sure to take a wide variety of science classes. Astronomy and astrophysics often blend elements of biology, chemistry and other sciences to better understand phenomena in the universe. Also keep an eye out for any summer jobs or internships in math or science. Even volunteer work can help bolster your resume.
Pursue a math- or science-related bachelor’s degree. While a bachelor in astrophysics is the ideal, there are many other paths to that field. You can do undergraduate study in computer science, for example, which is important to help you analyze data. It’s best to speak to your high school guidance counselor or local university to find out what degree programs will help you.
Take on research opportunities. Many universities have labs in which students participate in discoveries — and sometimes even get published. Agencies such as NASA also offer internships from time to time.
Finish a doctorate in astrophysics. A Ph.D. is a long haul, but the U.S. Bureau of Labor Statistics points out that most astrophysicists do have a doctoral degree. Make sure to include courses in astronomy, computer science, mathematics, physics and statistics to have a wide base of knowledge.
Natalie Hinkel, a planetary astrophysicist who was then at Arizona State University, gave a lengthy interview with Lifehacker in 2015 that provided a glimpse into the rewards and challenges of being a junior astrophysics researcher. She described the long number of years she has put into doing her research, the frequent job switches, her work hours and what it’s like to be a woman in a competitive field. She also had an interesting insight about what she actually did day to day. Very little of her time is spent at the telescope.
“I spend the vast majority of my time programming. Most people assume that astronomers spend all of their time at telescopes, but that’s only a very small fraction of the job, if at all. I do some observations, but in the past few years I’ve only been observing twice for a total of about two weeks,” Hinkel told Lifehacker.
“Once you get the data, you have to reduce it (i.e. take out the bad parts and process it for real information), usually combine it with other data in order to see the whole picture, and then write a paper about your findings. Since each observation run typically yields data from multiple stars, you don’t need to spend all of your time at the telescope to have enough work.”
Device for harnessing terahertz radiation might help power some portable electronics.
Terahertz waves are electromagnetic radiation with a frequency somewhere between microwaves and infrared light. Also known as “T-rays,” they are produced by almost anything that registers a temperature, including our own bodies and the inanimate objects around us.
Terahertz waves are pervasive in our daily lives, and if harnessed, their concentrated power could potentially serve as an alternate energy source. However, to date there has been no practical way to capture and convert them into any usable form.
Now physicists at MIT have come up with a blueprint for a device they believe would be able to convert terahertz waves into a direct current, a form of electricity that powers many household electronics.
Their design takes advantage of the quantum mechanical, or atomic behavior of the carbon material graphene. They found that by combining graphene with another material, in this case, boron nitride, the electrons in graphene should skew their motion toward a common direction. Any incoming terahertz waves should “shuttle” graphene’s electrons, like so many tiny air traffic controllers, to flow through the material in a single direction, as a direct current.
The researchers have published their results today in the journal Science Advances, and are working with experimentalists to turn their design into a physical device.
“We are surrounded by electromagnetic waves,” says lead author Hiroki Isobe, a postdoc in MIT’s Materials Research Laboratory. “If we can convert that energy into an energy source we can use for daily life, that would help to address the energy challenges we are facing right now.”
Isobe’s co-authors are Liang Fu, the Lawrence C. and Sarah W. Biedenharn Career Development Associate Professor of Physics at MIT; and Su-yang Xu, a former MIT postdoc who is now an assistant professor chemistry at Harvard University.
Breaking graphene’s symmetry
Over the last decade, scientists have looked for ways to harvest and convert ambient energy into usable electrical energy. They have done so mainly through rectifiers, devices that are designed to convert electromagnetic waves from their oscillating (alternating) current to direct current.
Most rectifiers are designed to convert low-frequency waves such as radio waves, using an electrical circuit with diodes to generate an electric field that can steer radio waves through the device as a DC current. These rectifiers only work up to a certain frequency, and have not been able to accommodate the terahertz range.
A few experimental technologies that have been able to convert terahertz waves into DC current do so only at ultracold temperatures — setups that would be difficult to implement in practical applications.
Instead of turning electromagnetic waves into a DC current by applying an external electric field in a device, Isobe wondered whether, at a quantum mechanical level, a material’s own electrons could be induced to flow in one direction, in order to steer incoming terahertz waves into a DC current.
Such a material would have to be very clean, or free of impurities, in order for the electrons in the material to flow through without scattering off irregularities in the material. Graphene, he found, was the ideal starting material.
To direct graphene’s electrons to flow in one direction, he would have to break the material’s inherent symmetry, or what physicists call “inversion.” Normally, graphene’s electrons feel an equal force between them, meaning that any incoming energy would scatter the electrons in all directions, symmetrically. Isobe looked for ways to break graphene’s inversion and induce an asymmetric flow of electrons in response to incoming energy.
Looking through the literature, he found that others had experimented with graphene by placing it atop a layer of boron nitride, a similar honeycomb lattice made of two types of atoms — boron and nitrogen. They found that in this arrangement, the forces between graphene’s electrons were knocked out of balance: Electrons closer to boron felt a certain force while electrons closer to nitrogen experienced a different pull. The overall effect was what physicists call “skew scattering,” in which clouds of electrons skew their motion in one direction.
Isobe developed a systematic theoretical study of all the ways electrons in graphene might scatter in combination with an underlying substrate such as boron nitride, and how this electron scattering would affect any incoming electromagnetic waves, particularly in the terahertz frequency range.
He found that electrons were driven by incoming terahertz waves to skew in one direction, and this skew motion generates a DC current, if graphene were relatively pure. If too many impurities did exist in graphene, they would act as obstacles in the path of electron clouds, causing these clouds to scatter in all directions, rather than moving as one.
“With many impurities, this skewed motion just ends up oscillating, and any incoming terahertz energy is lost through this oscillation,” Isobe explains. “So we want a clean sample to effectively get a skewed motion.”
One direction
They also found that the stronger the incoming terahertz energy, the more of that energy a device can convert to DC current. This means that any device that converts T-rays should also include a way to concentrate those waves before they enter the device.
With all this in mind, the researchers drew up a blueprint for a terahertz rectifier that consists of a small square of graphene that sits atop a layer of boron nitride and is sandwiched within an antenna that would collect and concentrate ambient terahertz radiation, boosting its signal enough to convert it into a DC current.
“This would work very much like a solar cell, except for a different frequency range, to passively collect and convert ambient energy,” Fu says.
The team has filed a patent for the new “high-frequency rectification” design, and the researchers are working with experimental physicists at MIT to develop a physical device based on their design, which should be able to work at room temperature, versus the ultracold temperatures required for previous terahertz rectifiers and detectors.
“If a device works at room temperature, we can use it for many portable applications,” Isobe says.
He envisions that, in the near future, terahertz rectifiers may be used, for instance, to wirelessly power implants in a patient’s body, without requiring surgery to change an implant’s batteries.
“We are taking a quantum material with some asymmetry at the atomic scale, that can now be utilized, which opens up a lot of possibilities,” Fu says.
This research was funded in part by the U.S. Army Research Laboratory and the U.S. Army Research Office through the Institute for Soldier Nanotechnologies (ISN).
Liquid water may still flow on Mars, but that doesn’t mean it’s easy to spot. The search for water on the Red Planet has taken more than 15 years to turn up definitive signs that liquid flows on the surface today. In the past, however, rivers and oceans may have covered the land. Where did all of the liquid water go? Why? How much of it still remains?
Observations of the Red Planet indicate that rivers and oceans may have been prominent features in its early history. Billions of years ago, Mars was a warm and wet world that could have supported microbial life in some regions. But the planet is smaller than Earth, with less gravity and a thinner atmosphere. Over time, as liquid water evaporated, more and more of it escaped into space, allowing less to fall back to the surface of the planet.
Where is the water today?
Liquid water appears to flow from some steep, relatively warm slopes on the Martian surface. Features known as recurring slope lineae (RSL) were first identified in 2011in images taken by the High Resolution Imaging Science Experiment (HiRISE) camera aboard the Mars Reconnaissance Orbiter (MRO). The dark streaks, which appear seasonally, were confirmed to be signs of salty water running on the surface of the planet.
“If this is correct, then RSL on Mars may represent the surface expression of a far more significant ongoing drainage system on steep slopes in the mid-latitudes,” a research team member told Space.com in 2012.
“The detection of hydrated salts on these slopes means that water plays a vital role in the formation of these streaks,” the study’s lead author, Lujendra Ojha, of the Georgia Institute of Technology in Atlanta, said in a statement. Vast deposits of water appear to be trapped within the ice caps at the north and south poles of the planet. Each summer, as temperatures increase, the caps shrink slightly as their contents skip straight from solid to gas form, but in the winter, cooler temperatures cause them to grow to latitudes as low as 45 degrees, or halfway to the equator. The caps are an average of 2 miles (3 kilometers) thick and, if completely melted, could cover the Martian surface with about 18 feet (5.6 meters) of water.
Frozen water also lies beneath the surface. Scientists discovered a slab of ice as large as California and Texas combined in the region between the equator and north pole of the Red Planet. The presence of subsurface water has long been suspected but required the appearance of strange layered craters to confirm. Other regions of the planet may contain frozen water, as well. Some high-latitude regions seem to boast patterned ground-shapes that may have formed as permafrost in the soil freezes and thaws over time.
The European Space Agency’s Mars Express spacecraft captured images of sheets of ice in the cooler, shadowed bottoms of craters, which suggests that liquid water can pool under appropriate conditions. Other craters identified by NASA’s Mars Reconnaissance Orbiter show similar pooling.
Evidence for water on Mars first came to light in 2000, with the appearance of gullies that suggested a liquid origin. Their formation has been hotly debated over the ensuing years.
But not everyone thinks that Mars contains water today. New research reveals that RSL may actually have formed by granular flows formed by the movement of sand and dust.
“We’ve thought of RSL as possible liquid water flows, but the slopes are more like what we expect for dry sand,” lead author Colin Dundas said in a statement. “This new understanding of RLS supports other evidence that shows that Mars today is very dry.”
That idea may have been washed away by the recent discovery of a possible subsurface lake near the Martian South Pole.
An underground lake?
Researchers made a big splash when they announced that Mars might be hiding a lake beneath its southern pole. The European Mars Express spacecraft used its Mars Advanced Radar for Subsurface and Ionosphere Sounding (MARSIS) to detect the proposed water. Ground-penetrating radar sent radar pulses to the surface, then timed how long it took for them to be reflected. The properties of the subsurface layers affect how long it takes for the beams to return.
MARSIS’ investigation revealed that the Martian south pole is composed of multiple layers of ice and dust to a depth of about nearly 1 mile (1.5 kilometers) spread over a 124-mile-wide (200 km) region.
“This subsurface anomaly on Mars has radar properties matching water or water-rich sediments,” Roberto Orosei, principal investigator of the MARSIS experiment and lead author of the new research, said in a statement.
MARSIS also revealed the presence of a subsurface lake among the pockets. According to the radar echoes, the lake is no more than 12.5 miles (20 km) across, buried nearly a mile beneath the surface. The scientists aren’t certain of the lake’s depth, but they have confirmed that it is at least 3 feet (1 meter) deep. According to the researchers, the lake must have salt to keep from freezing.
“This is just one small study area; it is an exciting prospect to think there could be more of these underground pockets of water elsewhere, yet to be discovered,” Orosei said.
Not all researchers are as certain about the presence of liquid water.
“I think it’s a very, very persuasive argument, but it’s not a conclusive or definitive argument,” Steve Clifford, a Mars researcher at the Planetary Science Institute in Arizona, told Space.com. “There’s always the possibility that conditions that we haven’t foreseen exist at the base of the cap and are responsible for this bright reflection.”
More than three decades ago, Clifford proposed that Mars could harbor liquid water beneath its polar caps in the same way that Earth does. On Earth, lakes beneath the Antarctic and Greenland ice sheets are created when heat from within the planets melt the glaciers in patches. Clifford told Space.com that a similar scenario could happen beneath the Martian polar ice caps.
“The bright spot seen in the MARSIS data is an unusual feature and extremely intriguing,” Jim Green, NASA’s chief scientist, said in a statement. “It definitely warrants further study. Additional lines of evidence should be pursued to test the interpretation.”
“We hope to use other instruments to study it further in the future,” Green said.
Liquid gold
Water may seem like a very common element to those of us stuck on Earth, but it has great value. In addition to understanding how Mars may have changed and developed over time, scientists hope that finding water will help them to find something even more valuable — life, either past or present.
Only Earth is known to host life, and life on our planet requires water. Though life could conceivably evolve without relying on this precious liquid, scientists can only work with what they know. Thus they hope that locating water on celestial bodies such as Mars will lead to finding evidence for life.
With this in mind, NASA developed a strategy for exploring the Red Planet that takes as its mantra “follow the water.” Recent orbiters, landers, and rovers sent to Mars were designed to search for water, rather than life, in the hopes of finding environments where life could have thrived.
That has changed, however, with the flood of evidence these robots have returned. Curiosity determined that Mars could indeed have supported microbial life in the ancient past, and the next NASA rover — a car-size robot-based heavily on Curiosity’s basic design — will blast off in 2020 to look for evidence of past Red Planet life.
Fast-moving consumers goods are non-durable products that sell quickly at relatively low cost.
FMCGs have low-profit margins.
Examples of FMCGs are Milk, gum, fruit and vegetables, toilet paper, soda, beer, and over-the-counter drugs like paracetamol and digene.
What are Fast-moving consumer goods (FMCG)?
The products that are always in demand, easy to buy, and sold quickly are called Fast-moving consumer goods (FMCG). FMCG products principally have meager profit margins, but they do wonders in the business sectors due to their higher demand. FMCGs generally spend less time on the shelves of the stores mainly due to two reasons firstly, higher in requests and secondly quick putrefaction. All the items in your nearby supermarket fall in the FMCGs sector.
Some common Fast-moving consumer goods are:
Fruits and vegetables, eggs, fish and meat, soft drinks, Dairy products, toiletries, bread, other baked items, grooming products, and some of the medications are some of the Fast-moving consumer goods.
Most of the time, FMCGs are sold in massive proportions at low prices. If the prices are set higher, FMCGs like fruits and vegetables, fish, meats, or dairy products can remain unsold as they forfeit their freshness shortly.
HOW DOES FMCG RUN?
FMCG category has a powerful present and future as this sector provides relief to people’s daily necessities effortlessly at affordable prices. For illustration, the office employees who have to rush in the morning prefer ready to make food or packed food to avoid delay reaching their offices. Likewise, the industry makes itself capable of providing medicines, personal grooming commodities, and many other daily requirements effortlessly. FMCGs require a dominant distribution system as this industry promises not to let the shelves of the marts be vacated.
Practically, the distribution system consists of two parts. The marketing happens between the manufacturers and consumers and where manufacturers trade the products through some third party.
CLASSIFICATIONS OF FMCG.
1.Durable products.
Durable products last on the shelves for a long time, i.e., for at least 3-4 years. Some of these products are home appliances, electronics items, furniture, tools, and stationery.
2. Non-durable products.
Non-durable products last on the shelves for a short duration, i.e., less than a year from their manufacturing date. Some of these products are food, beverages, cosmetics, and drugs.
STRUGGLES FOR FMCG COMPANIES.
FMCG products have low-profit margins and limited shelf existence. So to maintain fluency in the market, FMCG companies have to sell a large number of products with intelligent marketing and keeping high-quality products at a lower cost to gain permanent consumers.
Other struggles for FMCG are:
Delaying the expiration of perishable products (meats and dairy products).
Keeping a pocket-friendly price because consumers are becoming price-sensitive due to the increase of E-Commerce.
Producing products and packaging that are favorable to the environment.

Organizing or hosting up of services can be done in any sector that includes applications, Information Technology either its components or its functions done manually by providing access to external service suppliers or typically through online. The services offered by host are wide range that includes spectrum of offering, web-hosting, offline site backups, virtual desktops associated by cloud services. For cloud services we can mainly prefer apple brand smartphones as a premium customer as it has a delighted service separately for them in a hasty manner. The hosting services are of three different types for IT Operating Models: Owned, Hosted and Public cloud.
OWNED:
Fully Owned: The organization has their own platform for operating and managing services of IT hardware.
Partially owned: The organization has its hardware whereas data is operated by a third party working as a collocation service.
Outsourced: The association can own or may pay rent in owned manner, hardware or data center but only third-party has the power to control it.
HOSTED: In a third-party control hardware and data center are handled as they install and operate the as application as necessary.
PUBLIC CLOUD:
Infrastructure as a Service: Provides control of certain resources so the organization can install the operating system and other parts of software.
Platform as a Service: Allows you to access the platform alone that has an advanced package to install and run applications.
Software as a Service: Only allows you to enter a hosted software environment that is controlled fully by the provider completely except the modification in the users like changing, joining or deleting.
So, while looking deeper into it we can find the sub-categories of this hosted services briefly as this may clarify our thoughts about it.
With these details we come to know the meaning of hosting various kinds of services according to the expectations of users or the organization with respect to the operating models and the shared resources of hardware and data center.

Since the pandemic unleashed each country from every nook and corner of the world started the research on the virus to make a vaccines. Till date a lot of countries have produced innumerous vaccines. Following are some of the most widely used vaccines.
1.Covaxin
Released by Bharat Biotech, it has an efficacy of 78% against symptomatic cases. The phase 4 trials were started in June 2021. It constitutes an inactive form of the covid virus. This invokes the immune system which kills any such virus that enters the future. It is given in the form of 2 doses each 4 to 6 weeks apart. There may be side effects like pain, swelling, stiffness in the upper arm, etc. It has not been tested on infants, pregnant, and breastfeeding women.
2.Covishield
Developed by the Oxford-AstraZeneca, it is being manufactured by the Serum Institute of India (SII). It is also given in 2 doses but both are 12 to 16 weeks apart. When both doses are given 30 days apart it is 70% effective but when the doses are 2 to 3 months apart, the efficacy rises to 90%. It has the same side effects as covaxin and is also not tested on infants, pregnant, and breastfeeding mothers.
3.Pfizer
Developed by the German company BioNTech it is an mRNA bases vaccine that encodes the mutated form of the spike protein. Its efficacy is around 91% after the second dose. A gap of 3-4 weeks is recommended between the 2 doses. Side effects remain the same. It can be administered to children above 16 years of age.
