Time management

Time is nothing but the count of the life. It is measured in Hours, minutes and seconds. It is very important to manage the time as it is very precious and cannot come back once it is lost. It is also very important to utilize the time properly.

Managing the time is very important. Many of the people don’t know how to manage the time. Let us now know some of the time management techniques and how to use them.

•Make schedules:-

Making schedules is one of the best methods to manage the time. All you have to do is, think of the things what you have to do on a particular day and allot some particular time for each activity. Complete particular activity in the allotted time. When the work takes too much time, then leave it aside and go for another work. Whenever all the work is finished, go for the work which is unanswered in the beginning and complete it. This is how schedules helps for time management and makes the proper use of the time.

•Don’t spend much time on one thing:-

Spending much time on a particular thing disturbe the individual and disturbs the concentration. So, to focus on the work, an individual must go for some another work whenever they get bored on a particular work. So, it helps to focus on the work and for not wasting the time.

Time management is the process of planning and controlling how much time to spend on specific activities.
BENEFITS OF TIME MANAGEMENT :


The ability to manage your time effectively is important. Good time management leads to improved EFFICIENCY and productivity, less stress, and more success in life. Here are some benefits of managing time effectively:

  1. STRESS RELIEF :
    Making and following a task schedule reduces anxiety. As you check off items on your ” to- do” list, you can see that you are avoid feeling stressed out with worry about whether you’re getting things done.

  2. 2.MORE TIME :
    Good time management gives you extra time to spend in your daily life. People who can time- manage effectively enjoy having more time to spend on hobbies or other personal pursuits.
  4. MORE OPPORTUNITIES:
    Managing time well leads to more opportunities and less time wasted on trivial activities. Good time management skills are key qualities that employes look for. The ability to prioritize and schedule work is extremely desirable for any organisation.

  5. 4.ABILITY TO REALIZE GOALS :
    Individuals who practice good time management are able to better achieve goals and objectives, and do so in a shorter length of time.

  6. LIST OF TIPS FOR EFFECTIVE TIME MANAGEMENT:


  1. 1.SET GOALS CORRECTLY:
    Set goals that are achievable and measurable. Use the SMART method when setting goals. In essence, make sure the goals you set are specific, Measurable, Attainable, Relevant, and Timely.

  2. 2.PRIORITIZE WISELY :
    Prioritize tasks based on importance and urgency. For example, look at your daily tasks and determine which are :
  • Important and urgent : Do these tasks right away.
  • Important but not urgent : Decide when to do these tasks.
  • Urgent but not important: Delegate these tasks if possible.
  • Not urgent and not important : set these aside to do later.

  • 3.SET A TIME LIMIT TO COMPLETE A TASK :
    Setting time constraints for completing tasks helps you be more focused and efficient. Making the small extra effort to decide on how much time you need to allot for each task can also help you recognise potential problems before theyv arise. That way you can make plans for dealing with them.

  • 4.TAKE A BREAK BETWEEN TASKS:
    When doing alot of tasks without a break, it is harder to stay focused and motivated. Allow some downtime between tasks to clear your head and refresh yourself. Consider grabbing a brief nap, going for a short walk, or meditating.

  • 5.ORGANISE YOURSELF :
    Utilise your calendar for more long term time management. Write down the deadlines for projects, or for tasks that are part of completing the overall project. Think about which days might be best to dedicate to specific tasks. For example, you might need to plan a meeting to discuss cash flow on a day when you know the company CFO is available.

  • 6.REMOVE NON- ESSENTIAL TASKS :
    It is important to remove excess activities or tasks. Determine what is significant and what deserves your time. Removing non- essential tasks frees up more of your time to be spent on genuinely important things
  • IMPLICATIONS OF POOR TIME MANAGEMENT :
  • Let us consider the consequences of poor time management ;
  1. PLAN AHEAD :
    Make sure you start everyday with a clear idea of what you need to do- what needs to get done THAT DAY. consider making it a habit to, at the end of each workday, go ahead and write out your ” to- do” list for the next workday. That way you can hit the ground running the next morning.
  2. POOR WORKFLOW :
    The inability to plan ahead and stick to goals means poor efficiency. For example, if there are several important tasks to complete, an effective plan would be to complete related tasks together or sequentially. That translates to reduced efficiency and lower productivity.
  4. WASTED TIME :
    Poor time management results in wasted time. For example, by talking to friends on social media while doing an assignment, you are distracting yourself and wasting time.

  5. 3.LOSS OF CONTROL :
    By not knowing what the next task is, you suffer from loss of control of your life. That can contribute to higher stress levels and anxiety.

  6. 4.POOR QUALITY OF WORK :
    Poor time management typically makes the quality of your work suffer. For example, having to rush to complete tasks at the last minute usually compromises quality

  7. 5.POOT REPUTATION :
    If clients or your employer cannot rely on you to complete tasks in a timely manner, their expectations and perceptions of you rely adversely affected. If a client cannot rely on you to get something done on time, they will likely take their business elsewhere.

Ways to Manage Stress

Stress is part of being human, and it can help motivate you to get things done. Even high stress from serious illness, job loss, a death in the family, or a painful life event can be a natural part of life. You may feel down or anxious, and that’s normal too for a while. Talk to your doctor if you feel down or anxious for more than several weeks or if it starts to interfere with your home or work life. Therapy, medication, and other stategies help. In the meantime, there are things you can learn to manage stress before it gets to be too much. Consider these suggestions:

Exercise

To start with, physical activity can help improve your sleep. And better sleep means better stress management. Doctors don’t yet know exactly why, but people who exercise more tend to get better deep “slow wave” sleep that helps renew the brain and body. Just take care not to exercise too close to bedtime, which disrupts sleep for some people. Exercise also seems to help mood. Part of the reason may be that it stimulates your body to release a number of hormones like endorphins and endocannabinoids that help block pain, improve sleep, and sedate you. Some of them (endocannabinoids) may be responsible for the euphoric feeling, or “runner’s high,” that some people report after long runs.

People who exercise also tend to feel less anxious and more positive about themselves. When your body feels good, your mind often follows. Get a dose of stress relief with these exercises:

Applications

Animals

Since the time Earth developed the quality of sustaining life, life has always gone under the process of evolution. Life started from single celled organisms and developed stage by stage. One organism extinct to develop into its better developed species or even at times it happens that some animals get erased from the surface of the earth due to extreme environmental condition.

EXTINCT ANIMALS: Species of animals which existed in the surface of the earth once upon a time but has no current existence, this may have been a result of extreme environmental condition or some other condition for existence. For example, we have dinosaurs, Dodo.

ENDANGERED ANIMALS: The species of animals which have only a few animals left on the surface of the earth and are in the mouth of being extinct are known as endangered, currently this is a result of poaching i.e., unethical killing of wild animals with purpose or change in the climate due to pollution and other factors. For example, we have the Royal Bengal Tiger.

We cannot do anything for the species which are extinct but we can definitely take steps and save our endangered species. Poaching laws should be made stricter and it should be taken care that people follow them.

Different types of animals :

Scientists sort the different types of animals in the world into categories based on certain characteristics. Animals are generally grouped into six types of aninals. The system for animal classifications is called taxonomy.

The Animal Kingdom :

All animals belong to a biological kingdom called kingdom Animalia. This kingdom is then broken down into over 30 groups. About 75% of all species on earth are aninals. Animals are then broken down into two types : vertebrates and invertebrates.

* Animals with a backbone are vertebrates.

* vertebrates belong to the phylum called phylum chordata.

* vertebrates are classified into five classes. They are amphibians, birds, fish,mammals, and reptiles.

* Animals without a backbone are invertebrates.

* Most invertebrates are in the phylum Arthropoda.

1. Amphibians :

All amphibians are vertebrates, and they need moist environment or water to survive.

* They are cold- blooded.

* They absorb water and breathe through their thin skin

* They have at least one special king gland used for defense.

* Most follow the life cycle of egg-larva- adult.

* examples : frog , newts, salamanders, toads.

2. Birds

Birds are a type of warm- blooded vertebrate that are adapted to fly.

* Not all birds can fly, but they do all have wings.

* Birds have beaks that help them catch and swallow food.

* The digestive system of a bird allows it to eat whenever it can and digest that food later.

* Birds lay egg to reproduce.

* They are endothermic, mening they maintain their own constant body temperature.

* They are bipedal, which means they have two legs.

* They have hollow bones and their bodies are covered in feathers.

* Birds belong to the class called Aves.

* Examples : albatrosses, chickens, hummin birds, falcons, falmingoes, ostriches, owls, parrot, penguins, pigeons.

3. Fish :

Fish are also vertebrates, and they are considered the oldest-known vertebrates.

* They are ectothermic, or cold- blooded, which means they rely on their surroundings to regulate their body temperature.

* Fish have funs.

* Most, but not all, fish have bodies covered in scales and breathe through gills.

* Fish live under water.

* Examples : eels, hangfish, lampreys, minnows, rays, salmon, seahorses, sharks.

4. Mammals :

Mammals are another type of vertebrate that belongs to the class Mammalia.

* young mammals get nourishment from milk produced by their mothers.

* Most mammals have hair.

* Their jaw is hinged directly to their skull unlike all other vertebrates.

* Almost aĺl mammals give birth to live bsbies.

* They are endothermic, or warm- blooded.

* Examples : there are over 5500 living species of mammals all over the world. Aardvarks, bats, elephants, hamsters, human, rabbits, rhinoceroses, whales.

5. Reptiles :

Reptiles are thought to be the first vertebrates to live completely on land. But, not all reptiles live only on land today.

* They are cold- blodded, or ectothermic

* They lay eggs to reproduce.

* They have four legs or descended from animals with four legs.

* They breathe through lungs

* Their bodies are covered in scales or scutes.

* Examples : crocodiles, geckos, lizards, sea turtles, snakes, tortoises.

Invertebrates :

Approximately 95% of all animals are invertebrates. Invertebrates do not have a backbone. There are different types of invertebrates, but they all share a few characteristics.

• They are made up of many cells that work together, or multicellular.

• Most, but not all have tissues, cells that work together in a more complex way.

• Most, but not all, can move.

• There are over 35 phyla of invertebrates.

• They generally have soft babies.

● Types of Invertebrates :

There are eight phyla of invertebrayes that are alive today.

* Annelida – have a segmented body and primitive brain

* Arthropoda – have jointed appendages and an exoskeleton.

* Cnidaria – have tissues and an incomplete digestive system

* echinodermata – have some type of spiny structure on their bodies

* Mollusca – generally have sofy bodies and a hard exoskeleton.

* Nematoda – unsegmented with worm- shaped bodies

* platyhelminthes – have soft, ribbon- like worms with no respiratory system.

* porifera – multicellular organisms living in water with no organs or tissues.

Examples : anemone( cnidaria) , clams ( mollusca), coral,

Property Rights

What Are Property Rights?

Property rights define the theoretical and legal ownership of resources and how they can be used. These resources can be both tangible or intangible and can be owned by individuals, businesses, and governments. In many countries, including the United States, individuals generally exercise private property rights or the rights of private persons to accumulate, hold, delegate, rent, or sell their property. In economics property rights form the basis for all market exchange, and the allocation of property rights in a society affects the efficiency of resource use.

Understanding Property Rights

Property is secured by laws that are clearly defined and enforced by the state. These laws define ownership and any associated benefits that come with holding the property. The term property is very expansive, though the legal protection for certain kinds of property varies between jurisdictions.Property is generally owned by individuals or a small group of people. The rights of property ownership can be extended by using patents and copyrights to protect:

  • Scarce physical resources such as houses, cars, books, and cellphones
  • Non-human creatures like dogs, cats, horses or birds
  • Intellectual property such as inventions, ideas, or words

Other types of property, such as communal or government property, are legally owned by well-defined groups. These are typically deemed public property. Ownership is enforced by individuals in positions of political or cultural power. Property rights give the owner or right holder the ability to do with the property what they choose. That includes holding on to it, selling or renting it out for profit, or transferring it to another party.

Acquiring Rights to a Property

Individuals in a private property rights regime acquire and transfer in mutually agreed-upon transfers, or else through homesteading. Mutual transfers include rents, sales, voluntary sharing, inheritances, gambling, and charity. Homesteading is the unique case; an individual may acquire a previously unowned resource by mixing his labor with the resource over a period of time. Examples of homesteading acts include plowing a field, carving stone, and domesticating a wild animal. In areas where property rights don’t exist, the ownership and use of resources are allocated by force, normally by the government. That means these resources are allocated by political ends rather than economic ones. Such governments determine who may interact with, can be excluded from, or may benefit from the use of the property.

Private Property Rights

Private property rights are one of the pillars of capitalist economies, as well as many legal systems, and moral philosophies. Within a private property rights regime, individuals need the ability to exclude others from the uses and benefits of their property. All privately owned resources are rivalrous, meaning only a single user may possess the title and legal claim to the property. Private property owners also have the exclusive right to use and benefit from the services or products. Private property owners may exchange the resource on a voluntary basis.

Private Property Rights and Market Prices

Every market price in a voluntary, capitalist society originates through transfers of private property. Each transaction takes place between one property owner and someone interested in acquiring the property. The value at which the property exchanges depends on how valuable it is to each party. Suppose an investor purchases $1,000 in shares of stock in Apple. In this case, Apple values owning the $1,000 more than the stock. The investor has the opposite preference, and values ownership of Apple stock more than $1,000.

Financial Literacy

What Is Financial Literacy?

Financial literacy is the ability to understand and effectively use various financial skills, including personal financial management, budgeting, and investing. Financial literacy is the foundation of your relationship with money, and it is a lifelong journey of learning. The earlier you start, the better off you will be, because education is the key to success when it comes to money.

Read on to discover how you can become financially literate and able to navigate the challenging but critical waters of personal finance. And when you have educated yourself, try to pass your knowledge on to your family and friends. Many people find money matters intimidating, but they don’t have to be, so spread the news by example.

Understanding Financial Literacy

In recent decades financial products and services have become increasingly widespread throughout society. Whereas earlier generations of Americans may have purchased goods primarily in cash, today various credit products are popular, such as credit and debit cards and electronic transfers. Indeed, a 2019 survey from the Federal Reserve Bank of San Francisco showed that consumers preferred cash payments in only 22% of transactions, favoring debit cards for 42% and credit cards for 29%.

Other products, such as mortgages, student loans, health insurance, and self-directed accounts, have also grown in importance. This has made it even more imperative for individuals to understand how to use them responsibly. Although there are many skills that might fall under the umbrella of financial literacy, popular examples include household budgeting, learning how to manage and pay off debts, and evaluating the tradeoffs between different credit and investment products. These skills often require at least a working knowledge of key financial concepts, such as compound interest and the time value of money. Given the importance of finance in modern society, lacking financial literacy can be very damaging to an individual’s long-term financial success.

Being financially illiterate can lead to a number of pitfalls, such as being more likely to accumulate unsustainable debt burdens, either through poor spending decisions or a lack of long-term preparation. This in turn can lead to poor credit, bankruptcy, housing foreclosure, and other negative consequences. Thankfully, there are now more resources than ever for those wishing to educate themselves about the world of finance. One such example is the government-sponsored Financial Literacy and Education Commission, which offers a range of free learning resources.

Strategies to Improve Your Financial Literacy Skills

Developing financial literacy to improve your personal finances involves learning and practicing a variety of skills related to budgeting, managing and paying off debts, and understanding credit and investment products. Here are several practical strategies to consider.

Create a Budget—Track how much money you receive each month against how much you spend in an Excel sheet, on paper, or with a budgeting app. Your budget should include income (paychecks, investments, alimony), fixed expenses (rent/mortgage payments, utilities, loan payments), discretionary spending (nonessentials such as eating out, shopping, and travel), and savings.

Pay Yourself First—To build savings, this reverse budgeting strategy involves choosing a savings goal (say, a down payment for a home), deciding how much you want to contribute toward it each month, and setting that amount aside before you divvy up the rest of your expenses.

Pay Bills Promptly—Stay on top of monthly bills, making sure that payments consistently arrive on time. Consider taking advantage of automatic debits from a checking account or bill-pay apps and sign up for payment reminders (by email, phone, or text).

China’s 5 Year Plan (2021-2025): Proposed Dam on River Brahmaputra

The five-year plans are a sequence of economic and social development initiatives furnished by the CCP (Chinese Communist Party) since 1949. The five-year plans were inspired by the five-year plans from the USSR and the focus was on launching new schemes, reforms and setting new growth targets.

Since the 11th five-year plan (2006-2010), the Chinese government has mentioned it as ‘Guidelines’ instead of plans. Currently China is on its 14th five-year plan/ guidelines. Unlike the previous five year plans, there is no specific GDP growth target and instead, the government announced that growth would be kept in “reasonable range” and an annual target would be set based on the specific conditions each year. The focus of the current plan is on self-sufficiency as the country had to endure difficulty after the United States had restricted China’s major chip makers from using American technology. Other areas of focus will be on the above 7 percent growth in the research and development spending. The government will also try to raise the urban residents to 65 percent of the population while maintaining green development and increasing the life expectancy by 1 year. Infrastructure will also be an area of priority with a focus on high-quality development of the belt and road initiative.

One of the biggest infrastructure projects of the 14th The five-year plan (2021-2025) has been officially approved to build a series of dams in the lower reaches of the Yarlung Zangbo River, as the Brahmaputra is known in Tibet before it flows into India.

The proposed dam would be in Medog, Tibet region will have a maximum possible capacity of 60 gigawatts and could potentially produce 300 billion kWh annually. The location is an area called ‘the great bend’ also known as ‘Yarlung Tsangpo Grand Canyon’ where the river goes through a very drastic U-turn and then the river descents from an elevation of 3000 meters to around 800 meters. Due to the drastic elevation change, the river flow is quite strong and is also an ideal location to build the dam.

The location of the dam could be a strategically risky move by china as it is very close to the Indian border but the other issue is that this proposed dam can undermine the water security of India. India relies heavily on the Brahmaputra River for agriculture and various other purposes.  Due to this, the proposed Dibang Dam by India in downstream (Arunachal Pradesh) might be the solution to offset the effect of the Chinese proposed dam. Although the majority of the catchment area of Brahmaputra is on the Indian side there is still the issue of water flow from the upstream as Assam usually suffers from floods in the rainy season and any additional water flow from the Chinese dam would make the situation worse. The problem will not only affect India but also Bangladesh due to its low-lying land and flood-prone region. Problem is that the region is ecologically diverse and sensitive and any kind of development in this region will negatively affect the ecology of this region. Due to turbulent tectonic plates, there are high chances of landslides and earthquakes as well. India will have to be vigilant and develop its strategy according to the developments on the Chinese side.

Students and social service.

Man is a social being and social service is a must in a system of man-making education, There are so many kinds of social service and students have a lot of work to do in this field. They have some duties to remove illiteracy. They can hold night schools for the illiterate adults and give them lessons on the three R’s. They can remove bad customs and inform the people of the rights and duties. They can clean dirty ponds and maintain hygiene around their area. In times of emergency such as flood, famine and earthquake, they can take an active part in bringing relief to the sufferers like giving them food, clothes, and finding them shelter. In times of normalcy they can organise cultural functions for the poor villagers as we know that poverty is depressing but drudgery is killing but most of the time students waste their time in idle gossip, in roaming and in fruitless work. It is better to utilise the power of youth in socially productive work than to squander our precious time in loitering at the market place or before theatre hall. It is true also that the studies of students will be affected somewhat if they turn their attention to social service. But, on the whole, they will be gainer as social service will promote their fellow-feeling, increase their love for the country and develop their organising capacity.

High schools can deliver social services on campus or refer students to outside agencies for assistance like various NGO’s.

If a student utilizes his time fruitfully and in socially useful work he gets contentment. Contentment is his satisfaction with his position. Students should remember that they are born for the improvement of the society by instilling the spirit of service in them. They can help the mankind in the best possible way.

The value of social service should be taught to students to create inspiration in them. They should be enthused to pay their utmost strength and service to the society to make their existence meaningful.

Students can co-operate with people on matters of public interest such as education, sanitation, trade and commerce and be a part of that so that they can help more and more people.

Students have a spirit to work but the guardians and teacher should guide them in the right way. Social service can be safely managed if they can be guided properly. Our leaders should guide them in the right way.

Sonagachi: Asia’s largest red light district in the heart of Kolkata

Situated in North Kolkata, in the oldest part of 300 year old city situated on the banks of River Hooghly, is Sonagachi, Asia’s largest red light district whose narrow , rat infested lanes houses around 11, 000 sex workers.

Click on the link to know what are the red light areas.

SONAGACHI in Bengali means TREE OF GOLD. There is a fascinating story behind the origin of its name.

SONAGACHI- a place of SAINT and SIN

Sonagachi is named after a Muslim saint turned dacoit, Sanaullah. The area in olden times was known as the den of notorious dacoit Sanaullah who lived with his mother. After his death, when his mother lamented the loss of her son she heard a voice which said ,” Mother don’t cry, I have now become a Gazi”. Gazi which means a “warrior who help in the spread of Islam” is the title given to the Muslim saints. Thereafter, a mosque was constructed in his rememberance and many people came there for cures and the mosque came to be know as the Dargah of Sanaullah and the area as Sonagachi. This fascinating tale was traced by PT Nair, Kolkata’s “barefoot historian” in his book ‘ A History of Calcutta’s streets’.

Though the transformation from a dacoit to warrior may seem strange but it is pretty normal as there were many Bengali Hindu dacoits who were the devotees of Goddess Kali and a robin hood figure for the people.

Though there is no direct documentary tracing the reasons responsible for the transformation of Sonagachi into a Red light district but some stories blame the neighborhood of the area which was a business one. Sonagachi is in the neighborhood of Chitpur which many centuries back was a business center even before the arrival of the Britishers. Any place with large number of travellers or pilgrims in the British area was bound to have a red light area which housed brothels enclosing many women who were seen as nothing but a toy.

Brothels in those times were known to be owned by the prominent Bengali families . The now decrepit mansions which has suggestive names like “Prem kutir” houses and provides livelihood to thousands of woman living there.

SONAGACHI- where bounts of make up hides the pain

Majority of the sex workers there like any other red light district are trafficked . They were dubbed by husbands , lovers or by the well wishers in the false hope of a better future and “sold” to this area which has painful stories behind every gesture. The 10 by 10 rooms in the brothels provides a perfect balance of the personal + professional lives of the workers. The single bed with condoms stacked beneath the mattress and household utensils underneath the bed is a reminder of the family life for which these places and this profession provides the money for. The glossy make up, flashy lights , scented rooms and loud music is a facade to drown the cries of the children of sex workers and also the horrors faced by the workers.

To us , as the third persons the place may seem like hell , but for some workers it is a place of refugee which accepted and provided shelter to them when nobody else did. A sex worker told her story to Indian Express mentioning how she dreamt to be a teacher in a rural conservative household but since the idea of woman in the professional zone is strictly prohibited in a rural conservative home, she had to give up on her home until she found a “well wisher” who on the pretext of helping her get education sold her to these narrow lanes of Sonagachi , which after all these years are her safe haven.

Women here are scared of love because all they got in the name of love from the men outside is just hurt. Another sex worker recalled her leaving the brothel with the man she loved only to come to know months after being pregnant with his child that he already had two wives and in order to escape the physical torture , she had no where else but the lanes of Sonagachi to return.

The children of these workers have a hard time coming i terms with their mother’s profession. They have only their mother in terms of family , identity of the fathers being unknown . While some children slips into depression and denounce their mothers, the others leave their mother forever when they are able to stand on their feet while some understand the sacrifices she gave in terms of her body, soul and peace to provide for them.

Health concerns of the workers

The local government , a few years back had started the “Sonagachi project” which educates women about the use of condoms necessary to prevent HIV diseases. The result is that today the area as compared to other red light districts has low rate of Hiv.

During the covid lockdown, when there were no customers, local authorities and NGO provided ration here and educated the women about measures to keep themselves save from Covid-19. Authorities also ensured the vaccination of the workers.

How did the Earth come into being??

A whooping 7.9 billion people, 8.7 million discovered eukaryotic species and an estimated 1 trillion microbes- How did it all came into being? How did our Earth or even better, the solar system or the whole universe came into being?

Photo by Pixabay on Pexels.com

So, it all began about 13.8 billion years ago. There existed a single point, a minute, hot and really dense point which violently exploded-‘The Big Bang’, and it is how everything came into being- Matter, Energy space, universe, stars, solar system, me, you-everything. After the explosion took place, it expanded into what we today call the universe. And, what’s more interesting is the fact that it is still expanding, and this is how the scientists came to believe that it all began with a big bang.

Scientists divide the period after the big bang into 2 era-

  1. Radiation era
  2. Matter era

Radiation era

The period between 10^(-43) seconds (after the explosion took place)-the Planck era(here, the current laws of physics do not apply), to about 30,000 years after the big bang is referred to as the radiation era. During this period, the temperature of the atmosphere was soo high that there was no distinction between matter and radiation ,or even better, no matter existed.

It is divided into 7 era or epoch-

  1. Grand unification epoch- Named for the unification of 3 grand forces of nature- Electro-magnetic forces, Weak forces, Strong nuclear forces. With a temperature greater than 1029 K, it began 10−43 s after the big bang. At the end of this epoch, the strong nuclear force broke away from the other two.
  2. Inflationary epoch- With a temperature greater than 1032 K, it began 10−36 s after the big bang. As the name suggests, the universe rapidly expanded in this epoch. The universe, ta this time had electrons, quarks and antiquarks.
  3. Electroweak epoch- Here, now all the 4 forces of nature have split off. Temperature- 10^20 K and time after big bang- 10^(-32)s.
  4. Quark epoch- Temperature here is 10^16K and 10^-12 s have passed since the big bang. All of the ingredients required to form subatomic particles were present but the universe still was too hot and dense.
  5. Hadron Epoch- Temperature- 10^10 K and Temperature-10^-6 s. The universe has not finally cooled down enough for subatomic particles to form and hence, quarks bind to form protons and neutrons.
  6. Lepton epoch- Temperature- 10^ 12 K and finally, about1 sec have passed since the big bang.
  7. Nuclear epoch- Temperature-10^9 K and 100 s approximately have passed since the big bang.

In these last two epoch, when the universe has cooled down quite a lot, the protons and neutrons fuse together to form the very first chemical elements- Hydrogen and Helium. And now that our universe is capable of forming elements, it brings us to the end of radiation era and the matter era begins.

Matter Era

Matter era includes 3 epoch that spread over billions of years and include the formation of our galaxy, solar system and even the present day.

  1. Atomic epoch- With the temperature of 3000 K and time after big bang- 50,000 years, this epic marks the beginning of attachment of electrons to nuclei. This process is known as recombination.
  2. Galactic epoch- Now, 200 million years have passed since the formation of our universe. With the ability of universe to now form Hydrogen and Helium molecules, the universe is dotted with atomic clouds. Within the clouds, due to gravity, clusters were formed which later led to the formation of galaxies.
  3. Stellar epoch- 3 billion years have now passed. Within those clusters of clouds, now stars will be formed. Stars begin their lives as proto-stars. These are formed as a result of gravitational forces between particles of dust and gas and heat is generated due to friction and collision. When the proto-star becomes extremely hot, the process of thermonuclear fusion starts taking place. This is how stars generate heat and electricity. This heat within the clouds convert the already exiting elements into all others that are currently known to humankind. When stars burn themselves and are destroyed in explosion know as supernova, it destabilizes the heat cloud, which then begins to rearrange itself in the shape of a flattened disc. At the center a proto-star forms (eg.- our sun). The clumps of dust are flash heated and form chrondules that later from planetesimals by cohesion. These planetesimals then, later accrete to form what we call today as planets.

And this is how our solar system was formed about 4.5 billion years ago. It is located in the Milky Way galaxy’s Orion Star Cluster and has about 8 planets with a total of 63 moons. The inner 4 planets (also known as terrestrial planets) are separated form the outer 4(also known as jovian planets) by a belt of asteroids. Terrestrial planets are known as such because they are made of rocky material, have solid surface, do nor have rings and are relatively small. Earth, among these, is the only one to have a moon.

The jovian planets, on the other hand, have multiple moons, support ring system, have no solid surface and are immense in size. The Oort Cloud, a collection of icy debris, marks the edge of our solar system as the gravitational and physical influence of sun diminishes .

This is how our solar system and our Earth were formed. Now, can our solar system end? If yes, then how and by when? It’s a question for a later time.

CONSTITUTIONAL PROVISIONS RELATED TO ENVIRONMENT

Environmental legislation are often defined as, a set of laws and regulations which are aimed toward protecting the environment from harmful actions. In both the international commitments and constitutional framework of India, the need for protection and conservation of environment is reflected.

Constitutional Provisions

By the Constitution (Forty-Second Amendment) Act, 1976 , Article 48A was added as a part of Directive Principles of State Policy and Article 51A as a fundamental duty of every citizen of India.

Article 51A under Part IV A of the Indian constituition talks about the 11 fundamental duties that are expected to be performed by the citizens of India. One of these is to protect and improve the natural environment including forests, lakes, rivers and wildlife, and to have compassion for living creatures. Furthermore, Article 48 A, of the Directive Principles of State Policy (DPSP) enumerated in Part IV of the Indian Constitution says that the State shall aspire to protect and improve the environment and to conserve the forests and wildlife of the country.

Some of International Conventions for Environment Protection to which India is a Signatory :

Stockholm Convention

The objective of the convention is to target additional POPs for action, supporting safer alternatives, and make a POPs-free future. It calls to ban nine of the dirty dozen chemicals (key POPs), limit the use of DDT to malaria control. As per Article 25(4), India ratified the Convention in 2006.

Montreal Protocol 1987

The Montreal Protocol was negotiated and signed by 197 parties in 1987 with the aim to control the consumption and production of chlorofluorocarbons (CFCs) which is responsible for Ozone Layer depletion.

The adoption of the 2016 Kigali Amendment to the Montreal Protocol is projected to reduce future global average warming in 2100 due to hydrofluorocarbons (HFCs) from a baseline of 0.3–0.5°C to less than 0.1°C.

United Nations Framework Convention on climate change (UNFCCC)

It was signed in 1992 at the United Nations Conference on Environment and Development ( Earth Summit, the Rio Summit or the Rio Conference). The parties to the convention meet annually at the Conference of the Parties (COP) to review the progress under the convention. It aims to achieve stabilization concentration of greenhouse gases in the atmosphere at a certain level that would prevent the climate.

United Nations Convention to Combat Desertification (UNCCD)

It was established in 1994 with the aim to take care of and restore land and soil productivity, and to minimise impact of drought.

Human rights and armed conflict

Armed conflicts

Numerous armed conflicts are currently taking place around the globe, cost of which goes beyond the numbers deaths but it also includes the victims of the consequences of war.The number of indirect victims of armed conflicts is much higher than that of direct deaths.  Indirect death is mainly caused by some preventable infectious diseases, undernourishment , and pregnancy-related conditions. In addition to deaths, armed conflicts also lead to undernourishment, increased infant mortality rates, forced migration, refugees, destruction of infrastructure.

International armed conflict, internationalized armed conflict, and non-international armed conflict are the three types of conflicts recognized by International humanitarian law.

Human rights

“Human rights” can be defined as rights of all human beings, regardless of nationality, residence, gender, ethnic origin, race, religion, language or any other status. Everyone is equally entitled to their human rights without any discrimination. This belief is fairly new and it stems from an evolution of the reflection of human dignity over the past centuries.

After World War II, stronger ideas of human rights emerged . People wanted to make sure that they never again be unjustly denied freedom, food, and shelter. The calls for human rights standards to protect citizens from abuses by their governments, came from different parts of the world. These voices played an important role in the San Francisco meeting that drafted the United Nations Charter in 1945. United Nations was then established with the primary goal of maintaining international peace and preventing conflict.

International humanitarian law

Human rights during armed conflicts are infringed upon the most. Therefore, over the years, there has been much focus on the formulation of mechanism aimed at alleviating human suffering armed conflicts. International law of armed conflicts, of which humanitarian law is a part, tries to provide protection to victims of war and crimes.

FIBONACCI SEQUENCE! THE MAGIC!!!

Though mathematics is an interesting and beautiful subject, most of us find it difficult to learn. We often learn mathematics to do calculations and learn formulas to get good grades in the exams. Mathematics is a wonderful subject which we tend to apply in our day-to-day life. If you see maths through a different dimension, it will be as interesting as social media. We learn so many formulas and theorems, but where do we apply them? Think and come to a solution to make mathematics an interesting one. To prove mathematics an interesting subject, here come the Fibonacci numbers. Most of us have heard it once or twice in our classes when our teacher says about it. If you love to play with numbers, then Fibonacci numbers are the one. Let’s see how interesting these Fibonacci Numbers are!!

The Fibonacci Sequence in Nature

Fibonacci numbers are numbers, such that each number is the sum of the two preceding numbers starting from 0 and 1. The Fibonacci numbers or Fibonacci sequence are first used in the book, Liber Abaci, by Fibonacci which is used in the calculation of the growth of the rabbits. The Fibonacci numbers are closely related to the golden ratio. The ratio of the two consecutive Fibonacci numbers gives the golden ratio as n increases. {Golden Ratio: 1.61803398875}. Though, Liber Abaci contain the earliest description outside India, Indian mathematicians are the ones who described Fibonacci sequence as early as the sixth century.

Fibonacci Sequence

The Fibonacci day is celebrated on November 23rd every year. If we write it in mm/dd format, 11/23; it is also a Fibonacci number. The name Fibonacci is named after its inventor, Leonardo of Pisa, commonly known as Fibonacci was an Italian Mathematician, who was famous for his invention in the history of mathematics.

Leonardo of Pisa, commonly known as Fibonacci (1170 – 1250)

Let’s see the Fibonacci sequence with the example of rabbit, A farmer put a pair of rabbits on a closed surface. How many rabbits can be produced from the pair in a year, if it is that every month each pair produces a new pair which from the second month on becomes productive? The solution is the Fibonacci sequence. The sequence will go on like   1, 1, 2, 3, 5,….. and so on.

FIBONACCI SEQUENCE IN NATURE!!

  • In some flowers, the petals are arranged in the Fibonacci sequential arrangement which is enough to prove that Fibonacci sequences are available in nature too.
  • In the branches of plants, the leaves are spirally arranged in the Fibonacci sequence arrangement. In small plants, it will be 5 or 8. In larger ones, it will be 8 or 13 based on the growth of the plant.
  • The pattern of the seeds within the sunflower follows the Fibonacci sequence (1,1,2,3,5, …..).

Fine! Till now, we saw what is a fibonacci sequence, and who is the inventor and where can we see this fibonacci series. Now, shall we see where these fibonacci sequence are used practically? Yeah! Come on!

IN MATHEMATICS,

  • The Fibonacci numbers occur in the sum of the shallow diagonals of Pascal’s triangle.
Fibonacci sequence and Pascal’s triangle
  • The Fibonacci sequence is also used in the Pythagoras theorem. The hypotenuse of the triangle can be a Fibonacci number.
  • The Fibonacci sequence is also used in the network topology for parallel computing.

IN COUMPUTER SCIENCE,

  • The Fibonacci numbers are important in the analysis of algorithms (computational run-time analysis) of Euclid’s algorithm.
  • Its also used in the common factor tree method that is called a binary tree method which is the Fibonacci number minus one.
  • This Fibonacci sequence also used in the game called poker, it is a step in the game development.

Fibonacci sequence are used not only in these two fields but also in many other fields. To put it simply, I have given these two fields. As we saw earlier, fibonacci sequence can also be seen in nature. While contructing tall buildings, climb up and see from the top, this is also an example of a fibonacci sequence.

These are the various interesting facts in the Fibonacci sequence. It’s just a small part of mathematics. If we take an interest in various parts or topics in mathematics, we can make maths an interesting one. Mathematics is an ocean, where Fibonacci sequence is a small fish in it. Let’s try to catch various fishes like the Fibonacci sequence and make our lives a great one. If you find it interesting, just do some more research and excite by yourself like how I got excited!!

The Nightingale Of India

“As long as I have life, as long as blood flows through this arm of mine, I shall not leave the cause of freedom…I am only a woman, only a poet. But as a woman, I give to you the weapons of faith and courage and the shield of fortitude. And as a poet, I fling out the banner of song and sound, the bugle call to battle. How shall I kindle the flame which shall waken you men from slavery…”

Introduction

She was an Indian political activist and poet. A proponent of civil rights, women’s emancipation, and anti-imperialistic ideas, she was an important figure in India’s struggle for independence from colonial rule. Naidu’s work as a poetess earned her the sobriquet ‘the Nightingale of India’, or ‘Bharat Kokila’ by Mahatma Gandhi because of colour, imagery and lyrical quality of her poetry.

Birth and death

Born in a Bengali family in Hyderabad, Naidu was educated in Madras, London and Cambridge. Following her time in England, where she worked as a suffragist, she was drawn to Indian National Congress’ movement for India’s independence from British rule. She became a part of the Indian nationalist movement and became a follower of Mahatma Gandhi and his idea of swaraj. She was appointed as the President of the Indian National Congress in 1925 and later became the Governor of the United Provinces in 1947, becoming the first woman to hold the office of Governor in the Dominion of India.

Naidu’s poetry includes both children’s poems and others written on more serious themes including patriotism, romance, and tragedy. Published in 1912, “In the Bazaars of Hyderabad” remains one of her most popular poems. She married Govindarajulu Naidu, a general physician, and had five children with him. She died of a cardiac arrest on 2 March 1949.

Work

“Tell me no more of thy love, papeeha,
Wouldst thou recall to my heart, papeeha,
Dreams of delight that are gone,
When swift to my side came the feet of my lover…”

– A Love Song From The North by Sarojini
Naidu

1905: The Golden Threshold, published in the United Kingdom.
1912: The Bird of Time: Songs of Life, Death & the Spring, published in London.
1917: The Broken Wing: Songs of Love, Death and the Spring, including “The Gift of India” (first read in public in 1915) .
1919: Muhammad Jinnah: An Ambassador of Unity.
1943: The Sceptred Flute: Songs of India, Allahabad: Kitabistan, posthumously published.
1961: The Feather of the Dawn, posthumously published, edited by her daughter, Padmaja Naidu.
1971:The Indian Weavers.

After India attained independence, she became the first woman Governor of an Indian state, Uttar Pradesh. She served as governor till she passed away in March 1949, when she was working late in office.

As a Feminist

“Sarojini Naidu inspired the Indian Renaissance Movement and had a mission to improve the life of Indian woman.”

Bappaditya Bandopadhyay

Sarojini Naidu played an important role in women’s rights struggle in India. She helped in shaping Women’s Indian Association in 1917 with Annie Besant and others. The Association sought equal rights including the right to vote and represent. She presented the need to include more women in the Congress and in the freedom struggle. During 1918, British and Indian feminists including Naidu set up a magazine called “Stri Dharma” to present international news from a feminist perspective.

How to learn Typing and typing speed

How to increase typing speed? Tips to improve typing speed - inORGnet

The Most, if not all, careers involve some computer-based work and require strong typing skills. Information technology professionals, for example, must be efficient typists in order to write code for computer and software programs. Accuracy is equally as important as speed, as a simple typo could result in a system-wide error.

Now way day’s technology-driven world, students and young adults become familiar with computers at an early age. Some schools have stopped teaching typing altogether, assuming students already possess the skills necessary to be successful in the modern workplace, according to an article in MIT’s Technology Review.

without proper training and practice, many individuals resort to hunt-and-peck typing, or looking down at the keyboard to select the right keys one-by-one. Mobile technology, such as tablets and smartphones, have also increased reliance on hunt-and-peck strategies.

Preferred typing method is known as touch-type, or typing without looking at the screen. This is much more efficient than hunt-and-peck; the average person types at an average of 40 words per minute, but a person who relies on the touch-type method can exceed 75 words per minute, allowing them to complete their work much more quickly and with minimal errors.

You can prepare to enter the workforce, here are some pointers to improve your own typing skills:

1.) Use the correct starting position

When practicing your typing skills, it’s important to use proper hand placement. To start, keep your fingers positioned over the home row keys (left hand over the A, S, D, and F keys, and the right hand over the J, K, L, and ; keys), with your thumbs hovering over the space bar. From here, you can move your fingers slightly to reach neighboring keys. Your hands should always return this starting position.

These conventions are meant to help you familiarize yourself with the keyboard. As you become more experienced, you can experiment with different variations of this starting position to find the placement that is most comfortable and natural for you.

2.) Don’t look down your hands

Instead of looking down at your hands, focus on your screen. This can be difficult at first, especially if you have not yet mastered the exact placement of the keys. However, looking at the screen will help improve your accuracy because you will be able to catch your typos as they occur. You’ll also begin to memorize the placement of the keys, so you’ll be able to type more quickly as you practice.

3.) Maintain good posture

Sitting in an upright position is going to make it easier to type faster. If you are used to slouching in your chair or working from the couch, try moving to a straight-backed chair or working at your desk.

4.) Find a comfortable position for your hands

The wrong hand placement can make it uncomfortable to type for extended periods of time. The space bar of your keyboard should be centered with your body, so that you are not reading your screen or typing from an angle. As you type, rest your elbows on the table and keep your wrists slightly elevated. You should never bend or angle your wrists dramatically.

5.) Practice!

Nothing is mastered overnight, and in order to really improve your typing accuracy and speed, you need to practice every day. There are many websites that offer free typing skills tests and practice, such as Typing Academy, TypingClub and How To Type. It’s important to take your time with these typing exercises and assessments. Attempting to rush through them will only result in more errors at first. Trust that your speed will improve naturally as you become more familiar with the keyboard.

Improving your typing skills will not only make your student life much easier, it will benefit you in your future career as well. It might take a lot of practice to see improvement, but don’t give up. You’ll be typing like a pro in no time!

4 Renewable Energy Sources

Environment Power Renewable Energy Renewables

Renewable energy is now in the list of popularity for the highest demand in recent year.In one word, you can say renewable energy are the future solution.

What is Renewable Energy?

Renewable energy means it is possible to renew them.In simple word there is no end of this type of energy.

 with the growth of population on the earth. The demand of renewable energy is also increasing day by day.Here I have discussed about some of the renewable energy sources.

Some Renewable Energy Sources :

  1. Solar Energy:
  2. Source:The source of this type of energy is the Sun,the King of our Solar System. Solar Energy is usually produced from sunlight falls on our earth surface.
  3. Production: To produce the Solar Energy, a solar panel is used which convert the sunlight into current for the uses. These solar panel are made of crystalline Silicon or C-Si which are also called as solar grade silicon. Silicon are abundant in amount on earth surface and feasible for produce current from sunlight.
  4. Advantage:
  5. The source of solar energy as we know it is the sun has no end. So, this energy is available anytime.
  6.  28-34 panel of solar plate can generate currents needed for an average house. So, you can personally generate the current you need.
  7.  No CO2 is produced during any process. So, it is eco-friendly. Even the solar panel are able to recycle bind.
  8.  It does not harm environment in any way.
  9. Economically affordable.
  10. Disadvantage: During rain, the power production efficiency is quite low than the sunny day, but still it does not affect so much the efficient is lowered by 5% .
  1. Hydro energy:
  2. Source: The source of hydro energy is water .This energy are produced by water dam, preserver, mountain rivers, water fountains.
  3. Production: To produce this energy, the following speed of water should be very high. The water flow will rotate the turbine which generate the electricity.
  4. Advantage:
  5. Water as a source of hydro energy is in abundant amount.
  6. During generation of hydro energy, there is no chance for the production of greenhouse gas. So, the environment is not affected.
  7. It produce a lot of energy.
  8.  The water is also not pollute during its production.
  9. Disadvantage:
  10. To need a lot of space for construct a damn and preserver. It is quite complex to set the need equipment to produce Hydro energy and need so much money.
  11.  The production process does not harm the environment but the construction can definitely affect the nature.
  1. Wind energy:
  2. Source:Obviously the source of this energy is wind.
  3. Production: It is produced by windmill. A heavy 3 blade rotor is fixed on the top of the tower.The speed of wind flow helps to make the rotor move which produce electricity.The windmill is usually setup on seashore,meadows or in any windy places.
  4. Advantage:
  5. The wind is abundant in amount. So, there is no running out of wind energy.
  6.  No CO2 is produced so no harming effect on the environment.
  7. Wind is not polluted during production.
  8. Disadvantage:

need lots of money equipment and manpower to set up a windmill.

  1. Biomass energy:
  2. Source: It is understandable that Biomass are living plant object.
  3. Production:The produce this energy the plant object are chosen.Electricity produced by burring those plant parts.
  4. Advantage: the non-edible and useless parts of plant are used as biomass energy.
  5. Disadvantages: Low amount of Co2 is produced but it does not affect environment that way.
