Population control:Need of the hour

It’s a hard fact to digest that the population on the planet earth has bombastically raised to 7.9 billion. As a matter of fact it took 2 million years of human prehistory and history of world’s population to reach 1 billion and this number got multipled so fast that it took just 200 years to grow to 7 billion. India and china alone contribute to 36% in population of the total population of the world. And India is expected to add 273 million people to its population between now and 2050. A UN report said in 2019,forecasting that the country will cross China as the world’s most populous country by 2027.

Population growth in India

In 2019,India has an estimated population of 1.37 billion. But denying the fact the good news is that the fertility rate of women have dropped significantly. It has dropped down from 3.31 children per women in 2000 to 2.2 children per women in 2017.Over the period of time it is nearing the replacement rate of 2.1. In spite of the fact that the population policies, family planning and welfare programs undertaken by the government of India have lead to continuous decrease in fertility rate, yet the actual stabilisation of the population has not been achieved. There is also decline in decadal growth from 21.15% in census 2001 to 17.64% in census 2011.

Causes of overpopulation

1.The decline in death rate- Due to science and technology we have excelled ourselves in field of science and medicine. And as a result we have come up with better treatment facilities of any disease.

2.Agricultural Advancement- Agriculture advancement in 20th century have allowed humans to increase food production using fertilizers, herbicides, pesticides and yield further. This allowed humans with more access to food that leads to subsequent population explosion.

3.Better medical facilities- Technological innovation was perhaps the biggest reason why the balance has been permanently disturbed. Illness that had claimed thousands of lives until now were cured because of the invention of vaccines.

4.More hands to overcome poverty- Families that have been through poverty, natural disaster or are simply in need of more hands to work are a major factor for overpopulation. According to the UN the 48 poorest countries in the world are likely to be the Biggest contributors to population growth.

5.Technological advancement in fertility treatment- with the latest technological advancement and more discoveries in medical science, it has become possible for couples who are unable to concieve to undergo fertility treatment methods and have their own babies.

6.Lack of family planning- most developing nations have a large number of people who are illiterate, live below poverty line and have little or no knowledge about family planning. Those people are unable to understand the harmful effect of overpopulation and lack of quality education prompt them to avoid family planning measures.

7.Poor contraceptive use- Poor family planning on the part of partners can lead to unexpected Progencies. As per statistics 76% of women aged between 19 and 49 in great Britain used at least one form of contraceptive, whereas study by WHO shows that this figure drops to 42% in underdeveloped countries, which leads to higher birth rate.

Effects of overpopulation

1. Uneven relationship between resources and demography- earth can produce only substantial amount of resources like food and water which is falling short for current needs.

2.Degradation of environment- with the overuse of coal, oil, and natural gases, it has started producing some serious effects on our environment.

3.Conficts and wars- conflicts over water are becoming a source of tension between countries which would result in wars. Starvation is a huge issue that the world is facing and the mortality of children is being fuelled by it. Poverty is the biggest hallmark we see when talking about overpopulation.

4.Rise of unemployment- unemployment is a major cause of overpopulation. As there are fewer jobs to support a large number of people. This gives rise to theft, crime as people want to feed their families and provide them with basic amenities.

5.Pandemic and Epidemic- Overpopulation lead to unhygienic living conditions, malnutrition and inaccessible, inadequate or non extant health care for which poor are more likely to be exposed to infectious diseases.

6.Malnutrition, Starvation and famine- when the availability of resources is scarce, starvation, malnutrition along with ill health and disease caused by diet deficiency such as rickets become more likely.

7.Water shortage, sewage treatment, inadequate rainfall- Roughly 1% of the world’s water is fresh and accessible. Overpopulation is a major issue that creates immense pressure on the world’s fresh water supplies.

8.Extinction-the impact of overpopulation on the world’s wildlife is severe. As deemed for land grows, the destruction of natural habitat such as forest, becomes common.

9.Faster climate change- According to 97% scientific community, human activities are changing global temperatures. If more is not done to reduce individual carbon footprint on a large scaleb, large population may spped these changes up.

Solution to overpopulation

1.Better education- the fastest and most efficient way to stabilize the world population is to send girls to school and empower women and to give everyone access to and education on birth control.

2.Making people aware of family planning- we must focus on agressive campaigning to make people aware of the overpopulation and it’s adverse effects on the future generations to come. Public participation campaign is must needed to Make them aware. As a culture we need to emphasize the benefits of having one- child family.

3.Population Stabilization- Delay the age of first marriage but you may shrink the reproductive age by getting people to have their question first child later by spacing out the number of children.

4.Tax benefits or Concession- people having one chilld should be benefited by exemption from paying taxes as this would encourage others to have one child.

5.Knowledge of sex education- It is one thing we people don’t talk about. This should be spoken to people and imparted proper knowledge of the biology of human body.

Human wildlife conflicts: A complex problem

How would you react to a wild cheetah in your backyard or an elephant in your garden?

The rapidly growing human population and urbanisation has led to Human wildlife conflict (HWC) to its pinnacle. Human wildlife conflict (HWC) arises when animals cause a direct and reiterate threat to the safety or the livelihood of the people, leading to the persecution of that species.

Water tank destroyed by elephants in HWC, Namibia

These conflicts have posed a question that can human and wildlife coexist together? 

However, this is not a new storyline – the human and wildlife have coexisted for millennia but the situation is more frequent and aggressive than before. Becoming a global concern for conservation and development to go hands in hand. The need for development requires a lot of natural resources that put the lives and existence of many wildlife species into danger. 

HWC mostly affects large or carnivores from whom the humans feel threatened. Elephants, bears, big cats, primates, sharks, seals and many more. HWC also severely impacts the livelihoods, lives and security of the people from whom we ask to conserve the wildlife. There are many immense challenges around the HWC because the causes of these are very complex and poorly perceived. A single HWC has many socio-cultural, political and economical factors that need to be considered. From research and studies for a long time it has been clear that every HWC problem is different from the next and cannot be solved by the same methods used beforehand. Thus understanding the root cause of the conflict is much needed to mitigate the effect of such incidents. Efforts to address the situations without fully understanding the deep rooted causes and effects often leads to temporary solutions or worse exacerbate the situation in hand. 

HWC are substantially “human-human” conflicts as the heart of the conflict is between the different stakeholders. Sometimes there are several groups assessing different interests and needs. 

Even in some cases the success in species recovery has led to another HWC. For example where carnivores have recovered and expanded a huge population they pose a threat to villagers nearby and their livestocks. 

The reports by UNEP says that it is impossible to completely eradicate the HWCs but a systematic approach can be devised to minimise the effects of these conflicts. The policymakers have to devise policies that can reduce the conflicts and create an ecosystem of coexistence between people and animals. Such steps needed careful studies on prevention, mitigation, response and rehabiltalation with the apt support of the local communities and tribes. 

Bullying at workplace

We humans though imperfect are essentially kind, sensible, good natured creature. But deep down we are wired to be bad, blinked, idle, vain, vengeful, and selfish. There are characters that reveal the darker and less impressive aspects of human nature. One such character is bullying. Though bully may take up his character as impressive but the person who is bullied may be affected mentally, physically and psychologically. 
Bullying is common in our present day society. We see bullying or some likewise activities everywhere. There is no denying the fact that a person undermine another person to show his supremacy, be it in school or an organization. it is often subtle and hidden, profoundly affecting a substantial number of children and people of different age groups. Bully uses bullying to control behavior, personal agenda, or to fulfill his self serving motives. Bully may manifest itself into many forms. It can be physical, verbal, relational, etc. If you are the victim, the shadows of it reflect on your very face the moment you step out of your house for the office or your school. You usually start your day with pinch of anxiety in your head. Then you count down the days until the weekend or next vacation. 


A few examples of bullying include:

•targeted practical joke

•being purposely misled about work duties, like incorrect deadlines or unclear directions

•continued denial of requests for time off without an appropriate or valid reason

•threats, humiliation, and other verbal abuse

•excessive performance monitoring overly harsh or unjust criticism. 

Criticising or monitoring someone’s work is not always bullying. For example- objective and constructive criticism or disciplinary action related to workplace behavior or job performance is not considered bullying. But criticism meant to intimidate, humiliate, or single someone out without reason would be considered bullying.Bullying can be subtle. One helpful way to identify bullying is to consider how others might view what’s happening. This can depend, at least partially, on the circumstances. But if most people would see a specific behavior as unreasonable, it’s generally bullying.


Types of bullyingBullying behaviors might be:


•Verbal-This could include mockery, humiliation, jokes, gossip, or other spoken abuse.

•Intimidating-This might include threats, social exclusion in the workplace, spying, or other invasions of privacy.Related to work performance. Examples include wrongful blame, work sabotage or interference, or stealing or taking credit for ideas.

•Retaliatory-In some cases, talking about the bullying can lead to accusations of lying, further exclusion, refused promotions, or other retaliation.

•Institutional-Institutional bullying happens when a workplace accepts, allows, and even encourages bullying to take place. This bullying might include unrealistic production goals, forced overtime, or singling out those who can’t keep up.According to 2014 research from the Workplace Bullying Institute, people believed that targets of bullying were more likely to be kind, compassionate, cooperative, and agreeable.


Bullying may occur more frequently in work environments that:


•are stressful or change frequently•have heavy workloads

•have unclear policies about employee behavior

•have poor employee communication and relationships

•have more employees who are bored or worried about job security. 


Bullying can have significant, serious effects on physical and mental health.


Physical health effects of bullying

If you’re being bullied, you may:

•feel sick or anxious before work or when thinking about work. 
•have physical symptoms, such as digestive issues or high blood pressure

•have a higher risk for type 2 diabetes

•have trouble waking up or getting quality sleep. •have somatic symptoms, such as headaches and decreased appetite

. 
Psychological effects of bullying may include:

• thinking and worrying about work constantly, even during time off.

 •dreading work and wanting to stay home.

 •needing time off to recover from stresslosing interest in things you usually like to do.

 •increased risk for depression and anxiety.

 •suicidal thoughts. 

•low self-esteem. 

•self-doubt, or wondering if you’ve imagined the bullying. 

How does bullying affect the workplace?

Workplaces with high rates of bullying can also experience negative consequences, such as:


•financial loss resulting from legal costs or bullying investigations.

 •decreased productivity and morale•increased employee absences. 

•high turnover rates.

 •poor team dynamics.

 •reduced trust, effort, and loyalty from employees. People who bully may eventually face consequences, such as formal reprimands, transfer, or job loss. But many types of bullying aren’t illegal.
When bullying isn’t addressed, it becomes easier for people to continue bullying, especially when the bullying is subtle. Bullies who take credit for work or intentionally make others look bad may end up receiving praise or being promoted.
What to do if you’re being bullied at work When experiencing bullying, it’s common to feel powerless and unable to do anything to stop it. If you try to stand up to the bully, you may be threatened or told no one will believe you. If it’s your manager bullying you, you may wonder who to tell.
First, take a moment to remind yourself that bullying is never your fault, regardless of what triggered it. Even if someone bullies you by making it seem like you can’t do your job, bullying is more about power and control, not your work ability.


Begin to take action against bullying with these steps:


•Document the bullying-Keep track of all bullying actions in writing. Note the date, the time, where the bullying took place, and other people who were in the room.•Save physical evidence-Keep any threatening notes, comments, or emails you receive, even if they’re unsigned. If there are documents that can help prove bullying, such as denied PTO requests, overly harsh commentary on assigned work, and so on, keep these in a safe place.

•Report the bullying-Your workplace may have a designated person you can talk to if you don’t feel safe talking to your direct supervisor. Human resources is a good place to start. It’s also possible to talk about the bullying with someone higher up if your supervisor is unhelpful or is the person doing the bullying.

•Confront the bully- If you know who’s bullying you, bring along a trusted witness, such as a co-worker or supervisor, and ask them to stop — if you feel comfortable doing so. Be calm, direct, and polite.

•Review work policies- Your employee handbook may outline steps of action or policies against bullying. Also consider reviewing state or even federal policies about the type of bullying you’re experiencing.

•Seek legal- Consider talking to a lawyer, depending on the circumstances of the bullying. Legal action may not always be possible, but a lawyer can offer specific advice.

•Reach out to others- Co-workers may be able to offer support. Talking to your loved ones about the bullying can also help. You can also talk to a therapist. They can provide professional support and help you explore ways to cope with the effects of bullying while you take other action.


How to help when you witness bullyingIf you witness bullying, speak up! People often say nothing out of fear they’ll become targets, but ignoring bullying contributes to a toxic work environment.
Workplace policies against bullying can help people feel safer about speaking up when they see bullying happen.


If you witness bullying, you can help by:


•Offering support-Support could involve acting as a witness if the person targeted wants to ask the bully to stop. You can also help by going to HR with your co-worker.

•Listening- If your co-worker doesn’t feel safe going to HR, they may feel better having someone to talk to about the situation.

•Reporting the incident-Your account of what happened could help your management team realize there’s a problem.

•Staying close to your co-worker, when possible- Having a supportive co-worker nearby could help reduce instances of bullying.

Bullying is a serious issue in many workplaces. While many companies have a zero-tolerance policy, bullying can sometimes be hard to recognize or prove, making it difficult for managers to take action. Other companies may not have any policies about bullying.
Taking steps to prevent workplace bullying can benefit organizations and the health of their employees. If you’ve been bullied, know you can safely take steps to combat the bullying without confronting the perpetrator. Remember to take care of your health first.

KNOW YOURSELF!

In this life race have we ever realized that somewhere we have lost ourselves. In socializing, in meeting new people, in getting involved with new identities everyday, somewhere we have lost our own identity. To achieve each and everything in life we have just lost ourselves.

The time which we spend in knowing someone for what so ever reason if we would have spent that time in acknowledging ourselves I think we would have discovered a lot ourselves. Knowing others are good in fact it is necessary to socialize but loosing your own identity is not good. We have to introspect ourselves daily.

Many times we do mistakes unknowingly and we don’t realize it and we continue doing same mistakes until someone else correct us for the same and then we feel a little embarrassed. We can prevent ourselves from such embarrassment if we everyday start introspecting. We have to understand that we are our own judge. No one knows us better than us. We are very much familiar with our own weak and strong points.

Introspecting makes you more strong. You will improve day by day. Because we are the master of our own sea. No one will help us to eradicate our shortcomings like the way the way we will do it. We have to be our own best friend!

Why bad memories are Vivid

Do you remember the time when you lost your dog who was the dearest to you or the time when you had an accident. If asked about recalling someone from your past maybe you will recall some tragic or painful memories related to them. Ever wondered why we remember the bad ones more vividly than the good ones even if the latter is more in numbers. 

We often tend to remember the bad memories and it has many psychological, physiological and evolutionary factors involved. 

We can say that humans are lovers of tragedy. We forget the happy moments very soon. They do not last for long. On the other hand, tragedy leaves a powerful impact on us. Its appeal feels eternal because our heart is affected by it very much. P.B Shelly, famous romantic era poet also quoted in his poem ‘To a Skylark’ that – “Our sweetest songs are those that tell of saddest thoughts” our best memories are from the negative memories because they have a strong impression on us. Moreover, people always try to find pleasure in tragedy. It attracts us toward it that’s why many of the greatest plays or movies in history have always tragedy involved in them. 

We have witnessed many musicians whose lives were more tragic and they created the best music inspiring from these tragedies. The audience also loved these songs because as I stated before we are lovers of tragedy. 

How memories are stored in our mind

When a memory is created it is stored in the brain in forms of neural connections of brains stimulated by proteins. Everytime we dwell in the memory or tell someone about it the connections become stronger. The memory will live with us forever if we visit it from time to time. Since the beginning people thought long memories are stable but that’s not perfectly true. Every time we revisit the connections get malleable and are subjected to differ. This means that they are not completely stable. Some memories can grow out of proportion. That’s why we see a person having a little incident with a spider in childhood can get an exaggerated phobia in their lifetime. 

Why bad is strong

Researchers have claimed that humans tend to remember the bad memories well. There can be many reasons for that. As a species we have to survive in the world and to do that we have to always evolve and learn from our mistakes. That’s why we remember the details of the bad memories so that it can be stored and used later when the same situation appears again. The lasting impact of negative memories is associated with the danger with it and our attention to the danger. We would be more attentive to a lion hiding in a garden rather than a beautiful flower in the same bushes in which the lion is hiding. We ignore the flower because it’s not dangerous compared to the lion. Also the strong memory of negatives is associated with the young age as this is the time we are in a more learning phase. As we grow old we tend to care less and focus on the positive. 

Whether it is good or bad, people have both. The ups and downs, the happiness and sorrow all are parts and parcels of life. One should always balance one’s focus between both to live the life fullest. 

The process used by every data analyst

the present world is creating data every single second ,and by analysing these footprint of data , data analyst predict the fate of any business. Behind the success and failure of any startup data played a major role. Data speaks if you understand it then you can get success every where but if you don’t understand what data actually speaks your startup, business will be failed and to understand the language of data a simple 5 step process is adopted by every data analyst. If you go through these steps then you can predict the fate of your startup today

Lets begin that process in brief
1 ask
2 prepare
3 process
4 analyse
5 share
6 act

Ask: it is the phase when a person should ask effective questions why he is starting the startup and what would be its outcome

Prepare: if he have clear picture about his startup the he should start to think what type of data would influence his startup and how he would collect it.

Process: when he have collected the data from different source then he must do processing of data because raw data has most of trashes that would deviate us from the ideal outcome

Analyse: after collecting and processing data,data should be analysed what it is telling what type of pattern you are observing in data what relationship you are getting from that data.

Share: when you have analysed data then share it with your startup partners and create strategies to achieve the ideal outcome

Act : now the final step comes when after making strategies act on them,do not change strategies if in minor losses because you have planned all the things and always collect data to verify your startegies.

Now you are a data analyst if you will apply this you would never fail in your life

Mask up India: Best alternative to reduce mass transmission

With business shutting and GDP hitting record low in decades, schools and educational institutes, malls, markets, religious institutions all being closed and normal life almost at a halt. This is definitely the worst crisis India has ever faced. Collapsed medical infrastructure has made the situation even worse.

Observing the international trends such as the two waves in Brazil, one mini wave followed by two serious waves in the UK, three waves in the USA etc, the second wave was surely expected in India as well. Nation’s health advisor has also hinted at a third wave in future with so many virus carriers in the country. 

Vaccines are the best defense against this disease but keeping in the mind population of the

Country and recent vaccine shortage it will take almost 3 years to inoculate the entire population of the country. Until then covid appropriate behaviour is the best alternative to reduce the mass transmission. It includes wearing masks, cleanliness and hygiene, frequent hand wash or using alcohol based sanitizer and maintaining social distance. 

Why mask is the key 

An independent small study in Beijing with families has shown that the efficiency of masks in the same household is 79% in preventing the transmission. Another study last year published in the “American Journal of Tropical Medicine and Hygiene” found that nations that mandated wearing masks have a lower mortality rate than the ones who did not. Many more such studies have been  published in the last year showing the world the way to reduce transmission. 

Situation in India

Even after the grim situation caused by the pandemic people in India are still blithe in their approach towards the virus. It is often seen people not following covid protocols, especially wearing a mask. It is generally believed by the authorities that Indians can be persuaded to wear a mask only by a lawful measure with hefty fines or punishments for non compliance. But these protocols cannot work until the public adopts them on their own wil when they see it as being in their best interests. 

How public can be persuaded to wear a mask

 A research team of Yale university doing the research in bangladesh has found that mask usage tripled when they were given away free and also some instruction by religious and community leaders. This leads to three times the usage of masks. Keeping volunteers in public 

Places to remind the people to wear a mask and give away masks to them who did not have any, showed an increase in mask usage from 13% to 40%. Another key factor was the quality of the mask. Masks need to be comfortable without compromising their filtering capacities. India has manufactured sufficient masks and has capacity to manufacture the same in future so supplies should not be an issue. Communication through the community leaders and social workers with the association of government can be the right step ahead. Addition to these creative and imaginative campaigning is needed to sensitise the public about the necessity of the mask and the right way to use it. These solutions may sound elementary but if India has to 

Stop the devastating effect of the third wave it is essential that these are considered and implemented effectively.     

Understanding Proportions with the help of Ratio

Ratios and proportions are widely known concepts. We have to deal with them on daily basis. Which makes is very essential to learn them properly. 

In math, both of these concepts are greatly related to fractions. It is because the ratio is fundamentally a fraction. And proportion is the comparison of two fractions. 

It is no wonder if you are vaguely familiar with ratios. For example, you would have come across situations where the ratio of one group is higher than the other.

Similarly, you might have an idea about proportions already. For instance, you know that a motorcycle is faster than a bicycle in the same way a sports car is faster than a normal car.

In this blog post, we will discuss ratios and propositions with examples, so that by the end of this post you will have no confusion. 

Definition – Ratios

A ratio compares the quantity of one kind to the quantity of another kind. For ratios to exist, the quantities should have the same units. 

Ratios are represented as:

a : b

The symbols of both slash (/) and colon (:) are used to represent a ratio. The first value, here a, is known as antecedent. The second value, b in this case, is called the consequent.

How many types of Ratios are there?

There are two types of ratio.

Compound Ratio

For two or more ratios, if we take antecedent as product of antecedents of the ratios and consequent as product of consequents of the ratios, then the ratio thus formed is called mixed or compound ratio. As, compound ratio of m : n and p :  q is mp : nq.

Duplicate Ratio

Duplicate ratio is the ratio of two equal ratios. For example, the duplicate ratio of the ratio x : y is the ratio x2 : y2.

Definition – Proportions

A proportion compares two ratios. Through a proportion, we get to know that in two ratios a : b and c : d, a is related to b in the same way as c is related to d. 

The proportion of two ratios is represented as:

a : b : :c :d  

The double semicolon (::) or equal to (=) tells that the two ratios mentioned are in equal proportion. The values a and d are known as extremes and the values b and c are known as means.

In a proportion “a : b :: c : d”

  • The mean between b and c is . 
  • c is third proportional to a and b.
  • d is fourth proportional to a, b and c.

In a ratio, one quantity is compared in terms of “times” with the other quantity. This means if A and B are in a ratio of 3:1, then A is 3 times the quantity of B.  

A proportion tells a person that two ratios in proportion increase or decrease in a similar way. 

We can see this in an example. Previously we discussed that in a cake recipe, flour is two times the quantity of oil. This recipe is to make a one-pound cake. 

To make a 2-pound cake, increase the quantity of both in the same way, we will multiply two on both sides.

= 2 x 2 : 2 x 1

= 4 : 2

This ratio is in proportion to our previous ratio 2:1. It can be written as 

2 : 1 :: 4 : 2

How to solve ratios?

It will be easy to calculate ratios with the help of an example.

Example:

In a fruit basket, there are 15 fruits. Out of these 15 fruits, 6 are bananas and 3 are apples. Find the ratio of 

  • Bananas to rest of the fruits
  • Apples to total fruits
  • Apples to bananas

Solution:

For Bananas:

To find in which ratio bananas are present in the fruit basket, we will have to subtract bananas from the total number of fruits. It is a “part to part” ratio.

Total number of bananas = 6

Total fruits in the basket   = 15

Fruits – bananas = 15 – 6 = 9

This means there are 9 more fruits in the basket. The ratio of bananas to the rest of the fruits is:

6 : 9

After dividing by 3: 

2 : 3

For apples to the total fruits.

We will not need to subtract no. of apples from no. of fruits in this part. This is because we have to find the “part to the whole” ratio.

No. of apples = 3

No. of total fruits = 15       

The ratio is:

3 : 15            

After simplifying,

1 : 5

Apples to bananas

It is also a “part to part” ratio. 

No. of apples = 3

No. of bananas = 6

The ratio is,

3 : 6

Simplifying: 

1 : 2

A proportion can be formed by multiplying or dividing the ratio by the same number on both sides. After that writing the new ratio in proportion (with double semicolon i.e ::) the old ratio.

We usually determine whether a proportion exists or not. We can prove this in 3 ways. Let’s see how to do that with the help of an example.

Example:

Prove that the ratios 4:8 and 2:4 are in proportion.

Solution:

Write both ratios in proportion.

4 : 8 :: 2 : 4

Simplify both ratios by dividing with the common numbers. We get,

 2 : 4 :: 1 : 2

By simplifying more, we get,

1 : 2 :: 1 : 2

As we know, if both ratios are equal, proportion exists between both of them.

Write the ratios in the fraction form and cross multiply the fractions.

½ = ½ 

2 = 2 

Both sides are the same. Hence, the proportion is true.

Solve the fractions for decimal numbers.

4/8 = ½ = 0.5

2/4 = ½ = 0.5

Both of the decimal values are the identical which means that the proportion exists between these two ratios.

Under this heading, we will solve the problems related to ratios and proportions. Proportion calculator could be very handy in case you are looking to solve the proportions.

  1. 1.    There are two buckets of water. In the first bucket we mix oil into the water in a ratio of 5:8. In the second bucket, we mix another fluid in a ratio of 3:5. Which ratio is bigger?

Solution:

Step 1: Solve fractions and convert them into decimal values.

5:8 = 5/8 = 0.625

4:5 = 4/5 = 0.6

Step 2: Compare both values.

 As 0.625 > 0.6, so the ratio 5:8 is greater than 4:5.

  • 2.    Find x in proportion, 2 : x : : 20 : 50.

Solution:

Step 1: Convert the ratio in fractions and solve them to find the variable x.

 2 × 50 = 20x

100 = 20x

x = 100/20

x = 5

Discover your calling

One good time, I was leafing through the pages of the book ” Who will cry when you die”.A master piece book authored by ‘Robin Sharma’. His books are helping people around the world live great lives.

The very first lesson of the book struck a chord in me when I first read it. It read ‘Discover your calling’. By this time I was caught up & couldn’t resist myself going through the description of the lesson and amaze myself. And the description went like this:-

“When I was growing up, my father said something to me, I will never forget, ” Son, when you were born, you cried while the world rejoiced. Live your life in such a way that when you die the world cries while you rejoice.”

We live in an age when we have forgotten what life is all about. We can easily post a photo on Instagram and Facebook and read the comments and talk to unknown people, but we have trouble walking across the street to meet a new neighbor. At present almost every country have their own missiles which can target with pinpoint accuracy, but we have trouble keeping a family meeting in our home, hanging out with friends, visiting a library and reading books. We have lost touch with our humanity. We have lost touch with our purpose. We have lost sight of the things that matters the most. In this lesson he asks us to ponder over some questions:-

• what impact will our life have on the generation that follows us?
• And what legacy will we leave behind after we have taken our last breath?

He says that one of the greatest lessons he has learned In his own life is that if we don’t act on life, life has a habit of acting on us. The days slip into weeks, weeks slup into months and the months slip into years. Pretty soon it’s all over and we are left with nothing more than a heart filled with over a life half lived. “What would we do if we could live our life over again? “

Before we answer to this question in deep sigh and say that “I’d like to be the person I could have been but never was. ” We need to find greater purpose of our life and invest our life in serving the humanity. We need make a lasting contribution through our work so that we can enjoy the journey of life before it is too late. We all have special talents that are just waiting to be engaged in a worthy pursuit. We are all here for some unique purpose, some noble objective that will allow us to manifest our highest human potential while we at the same time, add value to the lives around us. Finding our calling doesn’t mean we must leave the job we have now. It simply means we need to bring more of ourselves into our work and focus on the things we do best. It means we have to stop waiting for other people to make the changes we desire and as Mahatma Gandhi noted: “Be the change that you wish to see most in your world. “ And once you do, your life will change.

What is heat wave?

Science behind US and Canada’s heat wave.

• Canada is reeling under severe heat wave, which has caused an unprecedented 195 percent risk in sudden fatalities within the past few days.

• In Portland city in Oregon, US temperatures as high as 46 degree celsius were recently registered- just three degree short of the internal core temperatures of a cooked shrimps.

• On June 29, temperature in Portland advanced to 46.7 degree celsius.

• Canada too saw it’s highest temperature ever recorded in the country’s west. In Lytton in British Columbia, temperature soared to over 46 degree celsius last week.

Canada’s heat wave:Toll tops 800

Hundred of deaths were being investigated as heat related in the US states of Oregon and Washington and in Canadian province of British Columbia

• 800 sudden and unexpected deaths have been reported. The abnormal heat wave caused the temperature in the country to rise to 49.5 degree celsius, an all time record. The weather experts have blamed the heat dome effect for the sudden rise in temperature.

• The national oceanic and atmospheric Administration (NOAA) says that to understand what causes a heat dome, one should liken the Pacific Ocean to a large swimming pool in which the heater is turned on.

• Once the heater is on, the portions of the pool close to the heating jets will warm up faster & therefore the temperature in that area will be higher. In the same way, the western’s Pacific Ocean’s temperature have increased in the past few decades & are relatively more than the temperature in the eastern Pacific.

• The phenomenon causing the scorching heat is called “heat dome”. Hot air is trapped by high pressure fronts and as it is pushed back to the ground, it heats up even more.

This condition also prevents clouds from forming, allowing for more radiation from the sun to hit the ground.

•This strong change in the ocean temperature from the West to the East is what a team of scientists believe is the reason for the heat dome, which is when the atmosphere traps heat at the surface, which increses the formation of heat wave.

• To compare the reason that the planet Venus is the hottest in the solar system is because its thick cloud cover traps the heat at the surface leading to temperature as high as 471 degree celsius.
