WHAT IS THE DIFFERENCE BETWEEN WAVE ENERGY AND TIDAL ENERGY 

The oceans cover more than 70% of Earth’s surface and are constantly in motion. This movement contains a huge amount of energy that can be converted into electricity. Two important forms of ocean-based renewable energy are wave energy and tidal energy. Although both come from the sea, they are created in different ways and use different technologies.

What Is Tidal Energy?

Tides occur because of the gravitational pull of the Moon and the Sun on Earth’s oceans. As Earth rotates, this pull causes sea levels to rise and fall in a regular and predictable pattern, usually twice a day.

Tidal energy is generated by capturing this movement of water. One common method uses underwater tidal turbines, which look similar to wind turbines but are smaller and much stronger to withstand ocean currents. As tidal water flows past the blades, it turns the turbine, which powers a generator to produce electricity.

Another method involves tidal barrages. These are large barriers built across bays or estuaries. Water is trapped behind the barrage at high tide and then released at low tide, flowing through turbines to generate power.

Advantages of tidal energy:

● Highly predictable and reliable

● Produces clean, renewable electricity

● Long-lasting infrastructure

Limitations:

● Expensive to build

● Can affect marine ecosystems

● Suitable only in areas with strong tidal currents

What Is Wave Energy?

Wave energy comes from wind blowing across the surface of the ocean. The stronger and longer the wind blows, the larger the waves become. Unlike tides, waves vary depending on weather conditions.

Wave energy is captured using machines called wave energy converters. Some of these devices float on the ocean surface and move up and down with the waves. This motion drives pistons or hydraulic systems connected to generators. Other designs trap waves inside a chamber, forcing air through a turbine to generate electricity. Some wave energy systems are placed near the shore, while others operate offshore.

Advantages of wave energy:

● Large energy potential

● Does not produce pollution

● Can be installed near coastal areas

Limitations:

● Less predictable than tidal energy

● Technology is still developing

● Can be damaged by storms

Future of Ocean Energy

Scientists and engineers around the world are still improving these technologies to make them cheaper, safer, and more efficient. Countries with long coastlines, such as the UK, Portugal, Australia, and India, have great potential to benefit from ocean energy.

If developed successfully, wave and tidal energy could play a major role in reducing our dependence on fossil fuels, helping to fight climate change and provide clean, renewable power for future generations.

The Hidden Power of Endurance

THE POWER OF PERSISTENCE 

Life is rarely a smooth road. No matter who you are, where you come from, or what you are trying to achieve, obstacles are inevitable. Many people give up too early because they expect success to arrive quickly and effortlessly. When difficulties appear, they assume something is wrong with them or with their path. This belief is mistaken. Struggle is not a sign of failure—it is a natural part of progress.

Persistence is the ability to continue despite setbacks, failures, criticism, and exhaustion. It is not blind stubbornness, but the quiet decision to keep going when things become uncomfortable.

History, culture, and human experience repeatedly show that success belongs to those who can endure pain, delay, and disappointment without losing direction.

Fighting the Same Battle More Than Once

Margaret Thatcher once said, “You may have to fight a battle more than once to win it.” This simple statement reflects a hard truth about life. Very few victories are achieved in a single attempt. Whether it is a career goal, a business idea, a relationship, or a personal habit, failure often comes before success—and sometimes more than once.

Losing once does not mean the battle is over. It means you have learned something. If you quit after the first failure, defeat becomes permanent. If you return with experience, better preparation, and stronger resolve, your chances of success increase. Persistence gives you multiple opportunities to succeed.

In everyday life, this truth is easy to observe. You may fail an exam once, yet pass later. You may lose a job, only to find a better opportunity. You may make mistakes in a project, but correcting them can lead to stronger results. Winning often comes after several losses, not before them.

Fall Seven Times, Stand Up Eight

A Japanese proverb wisely says, “Fall seven times, stand up eight.” Falling is not the problem—staying down is. Every human being fails, stumbles, and feels defeated at some point. What separates those who succeed from those who do not is what they do after they fall.

After failure, you always have a choice. You can remain stuck, complain, and blame circumstances. Or you can stand up, adjust yourself, and move forward. Standing up one more time than you fall is what creates progress.

Practically, this means accepting mistakes without self-hatred, learning without self-pity, and trying again without fear of embarrassment. Each fall builds experience. Each recovery builds confidence. Over time, failure becomes less frightening because you know you can always rise again.

Keep Going Through the Hardest Phase

There are moments in life when difficulties surround you from all sides. Everything feels painful, confusing, and overwhelming. During such times, quitting may seem like relief. But this is exactly when endurance matters most.

Winston Churchill’s advice remains timeless: “If you are going through hell, keep going.” Stopping in the middle of suffering does not end it—it prolongs it. If you are already in a difficult situation, moving forward is often the fastest way out. Pain has an endpoint, but only if you continue.

Whether it is a demanding phase at work, learning a difficult skill, or dealing with a temporary personal crisis, persistence protects the effort you have already invested. Progress may be slow, but slow movement is still movement.

When Hardship Makes You Stronger

An Arabian proverb says, “Blows that do not break your back strengthen it.” Not every hardship is destructive. Many challenges are lessons in disguise.

Surviving pressure, criticism, failure, or loss builds emotional strength, mental endurance, and practical wisdom. Just as muscles grow by resisting weight, character grows by resisting adversity. Comfort may feel pleasant, but struggle builds resilience.

This does not mean you should seek suffering. It means you should not fear it. When difficulties arise, treat them as training rather than punishment. Each challenge prepares you for greater responsibility ahead.

Why Persistence Matters More Than Talent

Persistence does not guarantee instant success, but it guarantees growth. Growth leads to better decisions, stronger confidence, and higher chances of long-term success. People who persist develop patience, discipline, and emotional balance—qualities that often matter more than talent alone.

In personal life, persistence helps build healthy habits, stronger relationships, and self-respect. In professional life, it helps withstand competition, criticism, and uncertainty. Over time, persistence turns ordinary effort into extraordinary results.

You may feel tired. You may feel discouraged. You may feel like giving up. But remember—you do not need to win today. You only need to continue. Fight the battle again. Stand up one more time. Keep moving through the difficult phase. Let hardship strengthen you instead of breaking you.

Persistence is not loud or dramatic. It is quiet, repetitive, and often unnoticed. Yet it remains one of the most powerful forces shaping human success.

Do you know

WHY DOES A CLOCK GO ONLY UP TO 12?

Have you ever wondered why most clocks show numbers only from 1 to 12, even though a full day has 24 hours? The answer takes us back thousands of years, to ancient civilisations and their early understanding of time.

The Ancient Love for the Number 12

Long before modern clocks existed, ancient cultures—especially in Mesopotamia and Egypt—considered the number 12 very special. Historians believe this may have been because:

● There are 12 lunar cycles (months) in a year

● There are 12 prominent constellations in the night sky

● The number 12 is easy to divide (by 2, 3, 4, and 6)

Because of this, 12 became a convenient and meaningful number for measuring time.

Sundials: The First Clocks

One of the earliest timekeeping devices was the sundial. It worked using the Sun’s movement across the sky.

A sundial had:

● A flat surface marked with divisions

● A vertical stick or pillar called a gnomon

● As the Earth rotated, the Sun’s position changed, causing the shadow of the gnomon to move. Ancient sundials often divided the daylight—from sunrise to sunset—into 12 parts. The middle point marked midday, when the Sun was highest in the sky.

Dividing the Night

When people later learned to measure time at night using water clocks (clepsydra) and oil lamps, they divided the night into 12 parts as well. This led to the idea of a 24-hour day:

● 12 hours of day

● 12 hours of night

However, these early hours were not equal in length, because days are longer in summer and shorter in winter.

The Birth of Accurate Timekeeping

With the invention of mechanical clocks in medieval Europe, timekeeping became more accurate. By then, the 24-hour framework was deeply rooted, so people kept it—even though they now had better technology.

To make clockfaces easier to read, clockmakers continued using 12 numbers, allowing the hour hand to go around the dial twice a day.

AM and PM Explained

In countries like India, time is commonly shown using the 12-hour system, divided into:

AM (Ante Meridiem) – Before midday

PM (Post Meridiem) – After midday

So, 7:00 AM means morning, while 7:00 PM means evening.

What About the 24-Hour Clock?

Many countries use the 24-hour time system, especially in:

● Military

● Railways

● Aviation

● Hospitals

In this system:

● 1:00 PM becomes 13:00

● 8:00 PM becomes 20:00

In India, the 24-hour system is mainly used in transport schedules and defense services.

Why Not 24 Numbers on a Clock?

Although 24-hour clockfaces do exist, they are less popular. Why?

● The numbers are crowded and harder to read

● The 12-hour clock is simpler and more familiar

● People are used to dividing the day mentally into morning and evening

After all, no one wants a clock that causes a real time crunch!

Did You Know?

● Ancient Egyptians also divided the year into 360 days, another number linked to 12

● Some modern watches combine both 12-hour and 24-hour markings

● Digital clocks still follow ancient ideas, even with modern technology

Conclusion

A clock goes only up to 12 because of ancient beliefs, early tools like sundials, and human preference for simplicity. Even with advanced technology, we continue to use this age-old system—a perfect example of how history shapes everyday life.

Time may move forward, but its design still ticks to an ancient rhythm!

The one who became Khatu Shyam

THE DIVINE STORY OF BARBARIK 

In the sacred age of the Mahabharata, there lived a warrior whose valor was unmatched and whose devotion was pure. His name was Barbarik, the beloved grandson of mighty Bhima and the son of the valiant Ghatotkacha. Gifted by the Divine Mother herself, Barbarik possessed three celestial arrows, each filled with divine power. With these three arrows alone, he was capable of ending the great war of Kurukshetra in a single moment.

As the conch shells echoed across the battlefield, Barbarik arrived at Kurukshetra and stood calmly beneath a peepal tree, right between the armies of the Kauravas and the Pandavas. With folded hands and unwavering faith, he declared,

“I shall fight from the side that is losing.”

This vow, born out of compassion, stirred deep concern in the heart of Lord Krishna, the knower of all destinies. Krishna foresaw that such unmatched power, bound by an innocent promise, could destroy both sides and disrupt the divine purpose of the war.

To understand the depth of Barbarik’s strength, Krishna approached him along with Arjuna. Smiling gently, Krishna pointed to a tree and said,

“If you can pierce every leaf of this tree with a single arrow, I will accept your greatness.”

With humble reverence, Barbarik released his arrow. Miraculously, the arrow pierced every leaf, one after another. A single leaf fell to the ground unnoticed. Seeing this, Krishna softly placed His foot upon it. Yet the arrow, obedient to its master’s command, halted near Krishna’s feet.

Barbarik bowed and said,

“O Lord, there is still one leaf beneath Your foot. Please remove it. I instructed the arrow to pierce leaves—not Your divine feet.”

At that moment, Krishna understood that Barbarik’s power was not merely martial—it was governed by divine discipline and unwavering intent.

Knowing the danger that lay ahead, Krishna adopted the gentle form of a Brahmin and visited Barbarik’s camp at dawn. In a humble voice, He asked for alms. Barbarik welcomed Him with devotion and said,

“Ask for anything, revered one.”

The Brahmin smiled and replied,

“I shall ask for something you may not be able to give.”

Yet without hesitation, Barbarik agreed.

Then came the divine request: his head.

Without fear, without sorrow, and without hesitation, Barbarik bowed before Krishna. For the victory of dharma and the welfare of his ancestors, the Pandavas, he willingly offered his head in supreme sacrifice.

Before doing so, Barbarik expressed one final wish—to witness the great war. Moved by his devotion, Lord Krishna granted him divine vision and placed his sacred head upon a high place from where he could see the entire battlefield.

After bathing, praying, and singing hymns through the night, Barbarik offered his head to Krishna on Phalguna Shukla Dwadashi, attaining immortality through sacrifice.

As the war ended and the Pandavas debated over who deserved credit for victory, Krishna smiled and said,

“Let Barbarik decide.”

From his divine vantage point, Barbarik spoke the eternal truth:

“It was only Krishna’s Sudarshan Chakra that fought on both sides, and Draupadi herself appeared as Goddess Kali, drinking the blood of the unrighteous.”

Pleased beyond measure, Lord Krishna blessed Barbarik and said,

“In the age of Kaliyuga, you shall be worshipped in My own name. Whoever remembers you with faith shall never be defeated by despair.”

Thus, Barbarik became Khatu Shyam—

the God of the defeated,

the protector of the helpless,

the eternal symbol of sacrifice, devotion, and grace.

Even today, devotees bow before Khatu Shyam Ji, knowing that where hope fades, Shyam Baba stands as eternal support.

India’s Digital Payment Revolution

UNIFIED PAYMENTS INTERFACE (UPI)

India’s Unified Payments Interface, popularly known as UPI, has transformed the way people send and receive money. What began as a simple idea to make digital payments easier has today become a global benchmark for fast, secure, and inclusive payment systems.

A Cut Above the Rest

✂️ THE HISTORY OF SCISSORS 

With just a little squeeze, scissors can cut paper, string, fabric, and even hair. They are so common today that we hardly think about them—but scissors have a fascinating history that stretches back thousands of years. In fact, they are among the oldest tools still in everyday use.

✨ The First Snip: Ancient Beginnings

The earliest known scissors appeared in Ancient Egypt around 1500–1000 BCE. These early scissors were quite different from the ones we use today. They were made from a single piece of bronze, shaped like two blades joined by a flexible strip of metal. To cut something, the user had to squeeze the blades together and then let them spring back apart. These are known as spring scissors.

Because bronze was expensive, such scissors were mostly used by craftsmen for cutting cloth, leather, or papyrus.

🏛️ A Roman Revolution in Design

A major improvement came from the ancient Romans around the 1st century CE. They introduced pivoted scissors, where two separate blades were joined in the middle with a pin or screw. This allowed the blades to rotate smoothly, making cutting faster, easier, and more precise.

This design was so effective that it became the foundation for nearly all modern scissors. In many ways, the scissors you use today still follow the Roman idea!

🔨 Handmade Masterpieces of the Middle Ages

During the Middle Ages, scissors were handcrafted by skilled blacksmiths, especially in Europe. These scissors were made of iron or steel and were often beautifully decorated. Some had engraved handles or unique shapes, making them both tools and works of art.

At this time, scissors were expensive and valuable. Only tailors, barbers, weavers, and gardeners usually owned them. Many families passed scissors down from one generation to the next.

⚙️ The Industrial Age: Scissors for Everyone

The biggest change came in the 18th century. In 1761, an Englishman named Robert Hinchliffe became the first person to mass-produce scissors made entirely of cast steel. Using moulds allowed scissors to be made faster, cheaper, and with consistent quality.

This innovation made scissors affordable for ordinary households, and their use spread rapidly across the world.

✂️ Scissors Today: Tools for Every Task

Today, scissors come in countless shapes, sizes, and styles, each designed for a specific job:

● Safety scissors with rounded tips for children

● Hair-cutting scissors for barbers and stylists

● Fabric scissors for tailors and designers

●Shears for gardening and cutting thick materials

● Surgical scissors used by doctors

● Left-handed scissors, designed to fit comfortably

● Modern scissors are made from stainless steel, plastic, titanium, or ceramic, and many have soft grips for comfort.

Despite all these changes, the basic principle remains the same: two sharp blades working together to create a clean cut.

🤔 Did You Know?

✂️ The world’s largest pair of scissors is over 3.6 metres long—taller than a giraffe’s neck!

✂️ The word scissors comes from the Latin word “scindere”, meaning to cut.

✂️ Even though we say “a pair of scissors,” it is treated as a plural noun in English.

🌟 Conclusion

From ancient bronze spring scissors to today’s high-tech cutting tools, scissors have come a long way. Their simple yet clever design has stood the test of time, proving that sometimes the best inventions don’t need much changing at all. The next time you pick up a pair of scissors, remember—you’re holding a piece of history in your hand!

The Scientist Who Heard the Whisper of Plants

JAGDISH CHANDRA BOSE 

Sir Jagdish Chandra Bose (1858–1937) was one of India’s greatest scientists, whose work bridged physics, biology, and botany at a time when such interdisciplinary research was unheard of. He was a pioneer who proved that plants are living, sensitive beings, and he laid foundations for modern wireless communication—long before it became mainstream.

Early Life and Education: Jagdish Chandra Bose was born on 30 November 1858 in Mymensingh (now in Bangladesh), then part of British India. His father, Bhagawan Chandra Bose, believed strongly in Indian culture and education. Bose’s early schooling in a vernacular school helped him remain deeply connected to Indian traditions.

He later studied at St. Xavier’s College, Calcutta, under the guidance of Father Eugene Lafont. Bose went on to England, where he studied at Cambridge University, earning degrees in natural sciences.

Contributions to Science:

1) Pioneer of Wireless Communication

Before Guglielmo Marconi became famous for radio transmission, Bose demonstrated wireless communication using microwaves in the 1890s. He invented several instruments, including the mercury coherer, used for detecting radio waves.

Unlike many scientists of his time, Bose refused to patent his inventions, believing that scientific knowledge should benefit humanity freely.

2) Proving That Plants Feel

Bose’s most revolutionary work was in plant physiology. He invented a sensitive instrument called the Crescograph, which could measure tiny movements in plants.

Through experiments, Bose showed that plants: respond to heat, cold, light, noise, and chemicals; experience stress and fatigue; show reactions similar to pain and pleasure

His research challenged the belief that plants were lifeless and earned him international recognition.

Challenges and Recognition: As an Indian scientist under British rule, Bose faced discrimination and skepticism. Initially, he was paid less than his British colleagues. Despite this, his brilliance could not be ignored.

He was elected a Fellow of the Royal Society (FRS) in 1920 and knighted in 1917, after which he became known as Sir Jagdish Chandra Bose.

The Bose Institute: In 1917, Bose founded the Bose Institute in Calcutta, India’s first interdisciplinary research centre. It remains a leading scientific institution today and stands as a testament to his vision of independent scientific research in India.

Legacy: Jagdish Chandra Bose was more than a scientist—he was a thinker, philosopher, and patriot. He proved that Indian minds could lead global science, even during colonial times. His work continues to inspire scientists, environmentalists, and students across the world.

Conclusion: Sir Jagdish Chandra Bose’s life teaches us that true science is driven not by fame or profit, but by curiosity, courage, and compassion for life. By listening to nature and respecting knowledge, he left behind a legacy that still speaks to the modern world.

A Story of Dreams, Loss, and Resilience

THE STORY OF WASHING POWDER NIRMA 

In the late 1960s, washing clothes in India was expensive. Most families could not afford branded washing powders, and people mostly used soap bars to wash their clothes. At that time, a young man named Karsanbhai Patel decided to change this.

Karsanbhai Patel was working as a chemist in the Gujarat government. In his free time, he started making his own detergent powder at home. He carefully mixed chemicals in his backyard and tested the powder himself. Once he was satisfied with the quality, he packed it in small bags.

Every morning before going to work, he would take his bicycle and go door-to-door selling his detergent. He sold it for just ₹3 per kilogram, while other popular brands cost around ₹15. Many people were surprised that a good detergent could be so cheap.

At first, shopkeepers and big companies did not take him seriously. But housewives loved the product because it cleaned clothes well and saved money. Slowly, word spread from one home to another, and the demand grew.

Karsanbhai named his detergent “Nirma,” after his daughter. With the profits he earned, he set up a small factory. Over time, Nirma became one of India’s most popular detergent brands.

Tragically, she passed away later in a road accident, and after her death, the name Nirma took on a deeper emotional meaning for him. He continued to grow the brand, and it became both a business success and a lasting memory of his daughter.

In the 1980s, Nirma challenged big multinational companies and became a household name. Its catchy jingle—

“Washing Powder Nirma, Washing Powder Nirma…”

made it famous across the country.

The success of Nirma showed that hard work, innovation, and understanding the needs of common people can create something extraordinary. Karsanbhai Patel’s simple idea changed the way millions of Indians washed their clothes.

WHAT HAPPENS TO THE BODY WHEN A PERSON GETS ELECTROCUTED?

Electrocution occurs when electric current passes through the human body. Since the body itself functions through delicate electrical signals—especially in the nerves, muscles, and heart—an external electric shock can severely disrupt normal bodily functions. The effects of electrocution can range from mild injuries to fatal consequences, depending on factors such as the strength of the current, duration of exposure, and the path the electricity takes through the body.

Disruption of the Nervous System: The nervous system is highly sensitive to electricity. When an electric current enters the body, it interferes with normal nerve signals. This can result in sudden muscle spasms, loss of control over body movements, confusion, or even unconsciousness. In many cases, the muscles contract so tightly that the person is unable to let go of the electrical source, prolonging exposure and increasing injury.

Severe Muscle Contractions: Electric current causes involuntary and powerful muscle contractions. These contractions may lead to temporary paralysis, locking of the jaw or hands, and in extreme cases, fractures or dislocations caused by the sheer force of the muscle movement.

Effects on the Heart: One of the most dangerous consequences of electrocution is its impact on the heart. Electricity can disrupt the heart’s normal rhythm, causing conditions such as ventricular fibrillation, where the heart beats erratically, or cardiac arrest, where the heart stops altogether. Even relatively small amounts of current passing through the chest can be life-threatening.

Breathing Difficulties: Electrocution can paralyse the muscles responsible for breathing or interfere with the brain centres that control respiration. This may result in respiratory arrest, leading to a lack of oxygen supply to vital organs, particularly the brain.

External and Internal Burns: Electrical injuries often cause burns at the points where the current enters and exits the body. However, the most serious damage may occur internally. As electricity passes through tissues, it generates heat that can burn muscles, nerves, and organs beneath the skin. These internal burns are not always immediately visible but can be extremely dangerous.

Damage to Organs and Tissues: Electric current can destroy muscle tissue, leading to a condition known as rhabdomyolysis. The breakdown products of damaged muscles can enter the bloodstream and potentially cause kidney failure. Blood vessels and nerves may also be permanently damaged.

Effects on the Brain: Depending on the severity of the shock, electrocution can cause seizures, memory loss, long-term neurological problems, coma, or death. Brain injury may result either from the direct effect of electricity or from oxygen deprivation due to breathing or heart failure.

Factors That Determine Severity

The seriousness of electrocution depends on several factors, including:

● The voltage and strength of the current

● The duration of contact

● Whether the skin is wet or dry (wet skin conducts electricity more easily)

● The path taken by the current through the body

Conclusion : Electrocution is unpredictable and can cause serious internal injuries even when external signs appear minor. Immediate medical attention is essential in all cases of electrical shock. Understanding how electricity affects the body highlights the importance of electrical safety in everyday life.

A Thousand Years of Faith, Destruction, and Renewal

SOMNATH TEMPLE, GUJARAT 

The Somnath Temple, located at Prabhas Patan near Veraval on the coast of Gujarat, is one of the most sacred shrines of Hinduism. Dedicated to Lord Shiva, it is revered as the first among the twelve Jyotirlingas. Over the centuries, Somnath has come to symbolise not only devotion, but also the enduring spirit of Indian civilisation.

In recent times, the temple has been in the news for completing 1,000 years since the first recorded attack in 1026 CE, a milestone that highlights its extraordinary historical journey.

Sacred Origins and Importance: The name Somnath means “Lord of the Moon.” According to legend, Chandra (the Moon God) worshipped Lord Shiva at this site to be freed from a curse that caused him to wane. Pleased by his devotion, Shiva restored his brilliance and manifested here as a Jyotirlinga.

Ancient Hindu scriptures such as the Rig Veda, Shiva Purana, and Skanda Purana mention Somnath, indicating that it was regarded as a sacred site from very early times.

Early History and Rise to Prominence: Historically, Somnath grew into a grand and wealthy temple during the early medieval period. Under the Chaulukya (Solanki) rulers of Gujarat, especially King Bhima I, the temple was magnificently rebuilt in stone in the early 11th century, becoming an important centre of pilgrimage, learning, and culture.

The First Recorded Attack – 1026 CE

The first historically documented attack on the Somnath Temple occurred in January 1026 CE, when it was raided by Mahmud of Ghazni, ruler of the Ghaznavid Empire.

Despite resistance by local defenders, the temple was heavily damaged and plundered.

This event marks a turning point in Somnath’s history and is now widely recognised as the beginning of a long cycle of destruction and reconstruction. The year 2026 marks 1,000 years since this first recorded attack, bringing renewed attention to the temple’s legacy of resilience.

Cycles of Destruction and Reconstruction

After 1026 CE, Somnath was rebuilt several times by Hindu rulers and devotees:

● Reconstructed by Chaulukya kings after Mahmud of Ghazni’s raid

● Attacked again in 1299 CE by forces of Alauddin Khilji

● Rebuilt by the Chudasama rulers of Gujarat in the 14th century

● Damaged again in 1395 CE under Zafar Khan, founder of the Gujarat Sultanate

● During the Mughal period, especially under Aurangzeb, the temple faced further destruction and neglect

Each time, Somnath rose again—earning its reputation as a shrine that refused to disappear.

Rebirth in Independent India: After India gained independence, the reconstruction of Somnath became a matter of national pride. Sardar Vallabhbhai Patel strongly advocated rebuilding the temple as a symbol of cultural self-respect and renewal.

The present temple was completed and consecrated in 1951, marking one of the earliest large cultural reconstruction projects of independent India.

Architecture and Setting: The current Somnath Temple is built in the Chalukya style of architecture, noted for its balance, elegance, and intricate carvings.

● The shikhara (spire) rises over 150 feet

● It is crowned with a golden Kalash

● The temple faces the Arabian Sea, creating a powerful and serene backdrop

● An inscription near the shore famously states that there is no land between Somnath and the South Pole, reflecting ancient India’s geographical understanding.

Living Traditions and Festivals: Somnath remains a vibrant centre of worship. Daily Abhishek, Aarti, and Darshan rituals attract thousands of devotees. Major festivals such as Mahashivratri, the month of Shravan, and Kartik Purnima see large pilgrimages.

The sound of temple bells blending with ocean waves gives Somnath its unique spiritual atmosphere.

Nature’s Skilled Tree Drummers

WOODPECKERS 

Woodpeckers are fascinating birds best known for their strong beaks and rhythmic drumming sounds. They use their sharp, powerful beaks to peck holes into trees and wooden surfaces. This pecking is so fast and forceful that it produces a loud tapping or drumming sound, which can often be heard from far away.

Physical Features

Woodpeckers show great variety in appearance depending on their species. Their feathers come in many colours such as red, white, grey, green, and brown. Some species have striking red or yellow markings on their heads, making them easy to identify.

One remarkable feature of woodpeckers is the presence of special feathers near their nostrils. These act like filters and prevent tiny wood particles from entering their nose while pecking. They also have a long, sticky tongue that helps them pull insects out from deep cracks in trees.

Their stiff tail feathers play an important role too. When a woodpecker pecks at wood, these strong tail feathers act like a support or prop, helping the bird balance against the tree trunk.

Another unique feature is their feet. Woodpeckers have two toes pointing forward and two pointing backward on each foot. This toe arrangement helps them grip tree trunks firmly and stay steady while climbing and pecking.

Habitat and Distribution

Woodpeckers are found in many parts of the world, including forests, woodlands, and even parks and gardens. Most species prefer forested areas where trees provide food, shelter, and nesting spaces.

Scientists believe there are more than 180 species of woodpeckers worldwide. Some well-known species include the Gila woodpecker, red-headed woodpecker, and white woodpecker.

Food and Feeding Habits

Woodpeckers mainly feed on insects such as termites, beetles, ants, and grasshoppers. By eating harmful insects, they help keep forests healthy. Apart from insects, some woodpeckers also eat nuts, seeds, fruits, and berries. Certain species drink sap—the sweet, juice-like substance found inside trees.

Woodpecker Habits and Behaviour

Woodpeckers usually live in holes in trees. Often, they carve these holes themselves using their beaks.

Most species make their homes in forests, though some adapt well to human surroundings.

They use a variety of sounds such as drumming, chattering, and twittering to communicate.

Some woodpecker species are territorial and protect their nesting areas from other birds and animals.

Drumming is not only for finding food—it is also used to attract mates and mark territory.

Conservation and Threats

Due to large-scale deforestation, several woodpecker species are now endangered. The imperial woodpecker and the ivory-billed woodpecker are among the most threatened. In fact, some scientists believe the imperial woodpecker may have already become extinct.

Did You Know?

● Woodpeckers can peck wood up to 20 times in a single second.

● Their skulls are specially designed to absorb shock, protecting their brains from injury.

● A woodpecker’s tongue can be longer than its beak and wraps around its skull when not in use.

Conclusion

Woodpeckers are truly remarkable birds with unique adaptations that help them survive and thrive in their environment. From their powerful beaks and sticky tongues to their strong feet and tails, every feature has a purpose. Protecting forests is essential to ensure that these skilled tree drummers continue to be a part of our natural world.

WHAT ARE BIOMETRICS?

In an increasingly digital world, verifying identity accurately and securely has become essential. From unlocking smartphones to accessing bank accounts, biometrics play a vital role in modern authentication systems. But what exactly are biometrics, and why are they considered so reliable?

Meaning of Biometrics: The term biometrics comes from two Greek words: bios (life) and metron (measure).

Biometrics refers to the measurement and statistical analysis of unique physical and behavioural characteristics of individuals used to identify or verify a person’s identity.

Unlike passwords or ID cards, biometric traits are intrinsic to a person, making them difficult to steal, forget, or forge.

Biometrics was first used in ancient civilisations, long before modern technology existed.

Early Use of Biometrics:

● Ancient Babylon (around 500 BCE)

The earliest known use of biometrics is traced to ancient Babylon, where fingerprints were used on clay tablets for business transactions. People pressed their fingerprints into wet clay to seal contracts and confirm identity.

● Ancient China (around 300 BCE)

In China, fingerprints and handprints were used as marks of identification, especially in legal documents and criminal investigations.

● Modern Scientific Use

19th Century – British India

Modern biometric science began in British India.

Sir William Herschel, a British officer in Bengal (1850s), used fingerprints to prevent fraud in contracts and pension payments.

Later, Sir Francis Galton scientifically studied fingerprints and proved their uniqueness, laying the foundation of modern fingerprint identification.

Law Enforcement Adoption:

● Early 20th Century

Fingerprint identification was formally adopted by police forces in Europe and the United States, replacing earlier methods like anthropometry (Anthropometry is about measuring the human body, while biometrics focuses on identifying individuals using unique biological features.)

In Short

First known use: Ancient Babylon

Scientific development: 19th-century British India

Widespread adoption: 20th-century law enforcement

Biometrics, therefore, is both ancient in origin and modern in application, evolving from clay tablets to digital scanners.

Types of Biometric Identifiers: Biometrics are broadly classified into two categories.

1. Physical (Physiological) Biometrics

These are based on the physical features of the human body:

● Fingerprint recognition

● Iris and retina scans

● Facial recognition

● Hand geometry

● DNA analysis

Each of these traits is unique to an individual and remains largely stable over time.

2. Behavioural Biometrics

These are based on patterns of behaviour rather than physical appearance:

● Voice recognition

● Signature dynamics

● Typing rhythm (keystroke dynamics)

● Gait (walking style)

Behavioural biometrics may change slightly over time but still offer reliable identification when combined with other methods.

How Biometric Systems Work: A typical biometric system functions in three main steps.

● Enrollment – The individual’s biometric data is captured and stored in digital form.

● Storage – The data is converted into a biometric template and securely saved.

● Matching – During authentication, the live biometric sample is compared with the stored template to confirm identity.

Uses of Biometrics: Biometric technology is widely used across various sectors.

● Smartphones and personal devices (fingerprint and face unlock)

● Banking and financial services (secure transactions)

● Government identification systems (such as Aadhaar in India)

● Border control and immigration

● Attendance systems in schools and offices

● Healthcare and law enforcement

Advantages of Biometrics:

● High security – Unique to each individual

● Convenience – No need to remember passwords or carry cards

● Accuracy – Reduces identity fraud and duplication

● Efficiency – Quick and seamless authentication

Concerns and Limitations: Despite their benefits, biometrics also raise certain concerns.

● Privacy issues – Misuse or leakage of biometric data can have serious consequences

● Data security – Unlike passwords, biometric traits cannot be changed if compromised

● Cost and infrastructure – Advanced systems may be expensive to implement

● Errors – False acceptance or rejection can occur in some cases

Conclusion: Biometrics represent a significant advancement in the field of identification and security. By relying on unique human traits, biometric systems offer a blend of convenience, accuracy, and enhanced protection. However, their use must be balanced with strong data protection measures and ethical considerations to ensure trust and safety in the digital age.

As technology evolves, biometrics are set to become even more integrated into everyday life, shaping how we identify ourselves in a connected world.

Do You Know?

● Fingerprints begin forming before birth—around the 10th week of pregnancy—and remain unchanged throughout a person’s life.

● No two irises are alike, not even those of identical twins, making iris recognition one of the most accurate biometric methods.

● India operates the world’s largest biometric identification system, Aadhaar, which uses fingerprints and iris scans of over a billion people.

● Biometric data is stored as encrypted templates, not as actual images, to enhance security and privacy.

● Behavioural biometrics can identify a person even without touch, such as by analysing how they type or walk.
