A Celebration of the Puzzle That Sharpens the Mind

INTERNATIONAL SUDOKU DAY 

International Sudoku Day is celebrated every year on September 9 to honour one of the world’s most loved logic puzzles—Sudoku. This special day encourages people of all ages to enjoy solving Sudoku puzzles and experience the joy of exercising their brains through logic and concentration.

WHAT IS SUDOKU?

Sudoku is a number puzzle played on a 9×9 grid, divided into nine smaller 3×3 boxes. The aim is to fill the grid with the numbers 1 to 9 so that every row, every column, and every 3×3 box contains each number only once. Even though it uses numbers, Sudoku is not a mathematics puzzle. It is a puzzle of logic, observation, and reasoning.

Sudoku does not have a single founder, but its modern form is credited to Howard Garns, an American architect and freelance puzzle creator.

THE STORY IN BRIEF:

●Howard Garns (1979): Created the modern 9×9 puzzle and published it in the magazine Dell Pencil Puzzles and Word Games under the name "Number Place."

●Maki Kaji (1984): A Japanese puzzle publisher who introduced the puzzle in Japan and gave it the name Sudoku, meaning “single number.” He is widely known as the "Godfather of Sudoku" because he made the puzzle famous around the world.

So, Howard Garns created the modern Sudoku puzzle, while Maki Kaji popularised it and named it Sudoku.

WHAT HAPPENS TO AN AIRBAG AFTER A CAR CRASH?

Airbags are one of the most important safety features in modern cars. They are designed to protect passengers during a collision by reducing the impact on the head, chest, and body. But have you ever wondered what happens to an airbag after it saves someone in a crash?

HOW DOES AN AIRBAG WORK?

When a car crashes, sensors detect the sudden impact within milliseconds. They send a signal to the airbag system, which quickly fills the airbag with gas. The airbag inflates in about 20–40 milliseconds—faster than the blink of an eye—and forms a soft cushion between the passenger and the hard parts of the car.

WHAT HAPPENS AFTER THE CRASH?

After inflating, the airbag begins to deflate almost immediately through tiny holes. This allows the passenger to move and prevents the airbag from becoming a hard obstacle. The deflation takes only a fraction of a second.

Once an airbag has deployed, it cannot be used again. The fabric bag, inflator, and other components must be replaced with new ones.

CAN YOU DRIVE A CAR AFTER THE AIRBAG OPENS?

A car may still be drivable if the damage is minor, but it is not considered fully safe until the airbags and related safety systems are repaired. A warning light usually appears on the dashboard to show that the airbag system needs attention.

WHY MUST AIRBAGS BE REPLACED?

Airbags are designed for one-time use only. After deployment, the airbag module, sensors, and sometimes the seat belt pretensioners need inspection or replacement to ensure the car is safe for future travel.

DID YOU KNOW?

●Airbags inflate faster than the blink of an eye.

●Most airbags deflate within a second after opening.

●Modern cars can have 6 to 10 airbags, including front, side, curtain, and knee airbags.

Amazing Facts

●The first commercial airbags appeared in cars during the 1970s.

●Airbags work together with seat belts for the best protection.

●A deployed airbag may release a small amount of harmless powder, which helps it unfold smoothly.

CONCLUSION 

Airbags save thousands of lives every year by protecting passengers during accidents. Although they are used only once, their quick action can make the difference between a serious injury and a safe escape. That is why wearing a seat belt and keeping the airbag system in good condition are both essential for safe driving.

A World of Wonder and Entertainment

CIRCUS 

The circus is a colourful form of entertainment that has amazed people for hundreds of years. It brings together talented performers, exciting acts, music, laughter, and dazzling costumes under one big tent. A visit to the circus is filled with joy, surprise, and unforgettable memories for children and adults alike.

WHAT IS A CIRCUS?

A circus is a travelling or permanent show featuring a variety of performances such as acrobatics, juggling, clown acts, magic tricks, balancing acts, and aerial performances. Modern circuses focus mainly on human skills, creativity, and storytelling.

A BRIEF HISTORY OF THE CIRCUS 

The modern circus began in 1768 in England when Philip Astley, a horse rider, started performing tricks in a circular arena. Over time, circuses grew into grand shows with performers from many countries, becoming popular around the world.

AMAZING CIRCUS PERFORMERS 

Circuses are known for the incredible talents of their performers.

●Acrobats perform flips, jumps, and balancing acts.

●Jugglers keep several objects moving in the air at once.

●Clowns entertain the audience with jokes, funny actions, and laughter.

●Aerial artists perform breathtaking stunts on ropes, swings, and trapezes high above the ground.

●Magicians amaze people with exciting illusions and tricks.

THE CIRCUS TODAY 

Many modern circuses no longer use wild animals. Instead, they focus on human talent, music, dance, lights, and special effects. Famous circus groups, such as Cirque du Soleil, have transformed the circus into a spectacular artistic performance.

CHALLENGES AND SURVIVAL OF THE CIRCUS 

The circus has brought joy and excitement to people for generations, but today it faces many challenges. Television, movies, video games, and online entertainment have reduced the number of people visiting circuses. Many travelling circuses also struggle with rising costs, transportation expenses, and finding suitable places to perform.

Another major challenge has been the growing concern for animal welfare. Many countries have introduced strict rules or banned the use of wild animals in circuses. As a result, many circuses have changed their performances to focus on human talent instead of animal acts.

HOW THE CIRCUS IS SURVIVING 

To survive, modern circuses have reinvented themselves. They now feature breathtaking acrobatics, aerial performances, music, dance, storytelling, and advanced lighting and sound effects. These changes have made circus shows more artistic and family-friendly.

The circus continues to survive because of the dedication, courage, and creativity of its performers. By adapting to changing times while preserving its spirit of wonder and entertainment, the circus remains a unique and magical experience for audiences around the world.

DID YOU KNOW?

●The circus ring is usually 13 metres (42 feet) in diameter.

●The word circus comes from the Latin word meaning circle or ring.

●Clowns often spend years learning acting, comedy, and acrobatics.

●Some circus artists begin training when they are very young.

AMAZING FACTS 

●A trapeze artist can swing several metres above the ground.

●Jugglers can keep many balls, clubs, or rings in the air without dropping them.

●Circus performances combine strength, flexibility, balance, and teamwork.

●Every circus show requires careful practice and safety measures.

WHAT WE LEARN FROM THE CIRCUS 

The circus teaches us that success comes through hard work, courage, discipline, and teamwork. Behind every exciting performance are hours of practice and dedication.

CONCLUSION 

A circus is a celebration of talent, creativity, and happiness. It inspires us to dream big, face challenges with confidence, and enjoy the magic of human skill and imagination.

World Circus Day is celebrated every year on the third Saturday of April to honour the art, history, and performers of the circus around the world.

2026: 18 April 2026

2027: 17 April 2027

The day was established by the World Circus Federation in 2010 to promote circus culture and recognise the dedication of circus artists.

Empathy and understanding

THE STORY BEHIND EVERY PERSON 

We all see the world through our own experiences. Sometimes, this makes us misunderstand other people's actions and intentions. A simple story about four friends teaches us an important lesson about empathy and understanding.

A FRIENDSHIP WITH DIFFERENT PERSPECTIVES 

A lion, a horse, a koala bear, and a bird were the best of friends. They spent every day together and enjoyed each other's company. One day, the bird suddenly disappeared. A day passed, then another, and soon an entire month went by without any sign of him.

The three friends began wondering where the bird had gone. The lion believed the bird had gone on a long hunting trip because hunting was what the lion enjoyed most. The horse thought the bird must be travelling because travelling was his favourite activity. The koala bear guessed that the bird was taking a very long nap because sleeping was what he loved.

Finally, after a month, the bird returned. The friends eagerly asked him if he had been hunting, travelling, or sleeping. The bird smiled and explained that he was a migratory bird who travelled long distances to search for food, water, and suitable places to live. Sometimes those journeys took many weeks.

The three friends laughed as they realized that each of them had imagined the bird's life according to their own interests and habits.

THE REAL LESSON 

This story teaches us that we often judge others based on our own way of thinking. We assume that other people think, feel, and act just as we do. But every person has a different background, different responsibilities, and different reasons for making decisions.

Before forming an opinion about someone, we should try to understand their situation instead of making quick assumptions.

HOW IS THIS APPLICABLE IN OUR LIFE?

This lesson is useful in our everyday lives.

●A friend may refuse to join a trip, not because they do not value your friendship, but because they are facing financial or family problems.

●A classmate may seem quiet or distracted because they are dealing with difficulties that others cannot see.

●A family member may react differently to a situation because their experiences and feelings are different from yours.

●At school or work, misunderstandings often happen when we judge people without knowing the full story.

When we listen carefully and try to understand another person's point of view, relationships become stronger and kinder.

Moral of the Story

Never judge someone's actions only from your own point of view. Everyone has a story that you may not know. Understanding others with empathy and patience is the key to true friendship and a happy life.

WHY DO FORKS HAVE 4 TINES?

Every day we use a fork without giving it much thought. But have you ever wondered why most dinner forks have four tines instead of three, five, or six? The answer is a fascinating story of history, design, and practicality. The four-tined fork is often called the “Goldilocks number” because it is not too many, not too few—just right!

HOW FORKS EVOLVED OVER TIME 

Forks have been used for centuries and have changed a great deal over time. The earliest forks, used in the Middle East and later in Europe, usually had two tines. They were mainly used for holding or serving pieces of meat.

As dining habits changed, three-tined forks became popular. They could hold food better than two-tined forks, but many foods still slipped through the wider gaps. After years of experimentation, people discovered that four tines offered the best overall design.

WHY ARE FOUR TINES THE PERFECT CHOICE?

The four-tined fork became the standard because it provides the ideal balance of strength, comfort, and usefulness.

●Better grip: Four tines hold food securely without letting it slip.

●Easy to spear food: The tines are strong enough to pick up vegetables, pasta, fruit, and meat.

●Comfortable size: A four-tined fork is wide enough to hold food but still fits comfortably in the mouth.

●Strong and durable: The tines are thick enough to resist bending during everyday use.

WHY NOT FIVE OR MORE TINES?

A fork with five or more tines may seem like it would hold food better, but it also has drawbacks. More tines mean narrower gaps and thinner tines, making the fork less sturdy and sometimes harder to clean. Four tines provide the best practical “sweet spot” for most meals.

Did You Know?

●The word fork comes from the Latin word furca, meaning a pitchfork.

●Dessert forks often have three tines because they are designed for softer foods.

●Seafood forks may have two tines to help remove meat from shells.

Amazing Facts

●The four-tined fork has been the world's most common dinner fork for hundreds of years.

●Most forks are made from stainless steel, which is strong, rust-resistant, and easy to clean.

●Different types of forks are specially designed for fish, salads, desserts, and seafood.

CONCLUSION 

The humble fork is the result of centuries of thoughtful design. After many changes and improvements, four tines proved to be the “just right” number—strong enough to hold food, comfortable to use, and practical for almost every meal.

The Wise Red Ape of the Rainforest

ORANGUTAN 

Orangutans are among the most intelligent animals on Earth. Their name comes from the Malay words orang (person) and hutan (forest), meaning “person of the forest.” These gentle great apes live high in the tropical rainforests of Southeast Asia and spend most of their lives in trees. With their long arms, reddish-brown hair, and thoughtful eyes, orangutans are truly fascinating creatures.

HISTORIC BACKGROUND 

Orangutans have lived in Asian rainforests for millions of years. Today, they are found only on the islands of Borneo and Sumatra, while a third species, the Tapanuli orangutan, lives in a small part of Sumatra. Scientists believe orangutans share about 97% of their DNA with humans, making them one of our closest living relatives.

WHERE DO ORANGUTANS LIVE?

Orangutans live in dense tropical rainforests where they find plenty of fruits, leaves, flowers, bark, and insects to eat. Unlike gorillas and chimpanzees, they are mostly solitary animals, especially adult males.

AMAZING BODY FEATURES 

●Orangutans have very long arms that can stretch over 2 metres from fingertip to fingertip.

●They use their arms to swing and climb through trees.

●Adult males develop large cheek pads and throat pouches.

●Their strong hands and feet help them grip branches easily.

FOOD HABITS 

Orangutans are mainly fruit eaters. They love figs, mangoes, lychees, and durians. They also eat leaves, flowers, seeds, bark, honey, and insects. During seasons when fruit is scarce, they survive on other forest foods.

INTELLIGENCE OF ORANGUTANS 

Orangutans are excellent problem-solvers. They use sticks to collect insects or honey and leaves as umbrellas during rain. Every evening, they carefully build a new nest of branches and leaves high in the trees to sleep.

FAMILY LIFE 

A baby orangutan stays with its mother for 6–8 years, one of the longest childhoods among animals. Mothers teach their young how to find food, build nests, and survive in the forest.

WHY ARE ORANGUTANS ENDANGERED?

Orangutans are critically endangered because of:

●Deforestation.

●Palm oil plantations.

●Illegal hunting and wildlife trade.

●Forest fires.

Many organisations are working to protect their forests and rescue injured orangutans.

Did You Know?

●Orangutans are the largest tree-dwelling mammals in the world.

●They can live 35–50 years in the wild.

●Each orangutan builds a new sleeping nest almost every night.

●Their arms are much longer than their legs.

AMAZING FACTS 

●Orangutans can recognise themselves in a mirror.

●They have unique personalities, just like humans.

●They communicate through facial expressions, gestures, and long calls.

●A mother orangutan has one baby only every 7–9 years, making their population grow very slowly.

CONCLUSION 

Orangutans are gentle, intelligent, and important guardians of the rainforest. By protecting forests and wildlife, we help ensure that these “people of the forest” continue to live safely in their natural home for generations to come.

Choose Your Company, Choose Your Future

BAD COMPANY CAN DESTROY GOOD PEOPLE 

There is a famous saying: “We are the average of the five people we spend the most time with.” The people around us have a powerful influence on our thoughts, habits and decisions. Even a good person can slowly change if surrounded by negative influences. That is why choosing the right company is one of the most important choices in life.

WHAT IS BAD COMPANY?

Company means the people we spend our time with—our friends, classmates, neighbours, relatives or colleagues. We choose many of these relationships ourselves. Good company encourages kindness, honesty, discipline and hard work. Bad company, on the other hand, promotes habits that pull us away from our values.

Friends who bully others, cheat, disrespect teachers, fight or encourage harmful behaviour may gradually make such actions seem normal. At first, we may resist, but constant exposure can weaken our judgment without us even noticing.

HOW CAN BAD COMPANY CHANGE A GOOD PERSON?

A Hindi proverb says, “Gehu ke saath ghun bhi pis jaata hai,” meaning that when wheat is ground, the worms mixed with it are crushed as well. Similarly, innocent people may suffer because of the company they keep.

Bad company can:

●Encourage wrong habits and poor decisions.

●Damage our relationships with family and good friends.

●Reduce motivation to study or work hard.

●Affect our emotional and mental well-being.

●Lead us away from our goals and values.

As the Bible wisely says, “Walk with the wise and become wise, for a companion of fools suffers harm.”

THE POWER OF GOOD COMPANY 

Good friends help us grow. They motivate us to learn, respect others, work honestly and become better human beings. They celebrate our success, correct us when we are wrong and stand by us during difficult times.

Success becomes easier when we are surrounded by people who inspire us to do our best.

ASK YOURSELF THESE QUESTIONS 

A simple way to judge your company is to ask:

●Do I feel happy and motivated after spending time with my friends?

●Do they encourage me to do the right thing?

●Do they respect my values and goals?

●Do I feel pressured to break rules or behave badly when I am with them?

Your answers will reveal whether your company is helping you grow or pulling you down.

MORAL OF THE LESSON 

We cannot control the behaviour of others, but we can control whom we choose to be with. Choosing good company is choosing a brighter future. If you realise that your company is leading you in the wrong direction, have the courage to walk away before it is too late.

Did You Know?

●Human behaviour is strongly influenced by the people we spend time with through observation and imitation.

●Positive friendships improve confidence, academic performance and emotional well-being.

●Ancient scriptures and modern psychology both emphasise the importance of keeping good company.

Amazing Facts

●Good habits are often “contagious”—being around disciplined and positive people makes it easier to develop similar habits.

●Our brain naturally copies behaviours it sees repeatedly, even when we believe we are not being influenced.

●One good friend who inspires you can have a lifelong positive impact on your character and future.

Remember: Your company shapes your character, and your character shapes your destiny.

A Timeless Teaching from the Valmiki Ramayana

अकुर्वन्तोऽपि पापानि पापसंस्रयात्। परपापैर्विषं यथा॥

सरल अर्थ: जो स्वयं पाप नहीं करते, वे भी पापियों की संगति के कारण दण्ड भोग सकते हैं; जैसे साँपों से भरे तालाब की मछलियाँ भी साँपों के साथ मार दी जाती हैं।

Meaning: Even those who have not committed any wrong may suffer because they associate with wrongdoers—just as innocent fish in a pond full of snakes are killed along with the snakes.

This ancient teaching reminds us that our companions can affect our destiny, even if we do not intend to do wrong ourselves.
