Why did UTC replace Greenwich Mean Time?

The Coordinated Universal Time (UTC) replaced the Greenwich Mean Time (GMT) as the world standard of time on January 1, 1972. For 50 years now, UTC has been the standard that is used to set all time zones around the globe.

Time is now an integral part of our lives every day. We wake up at a particular time, go to schools or offices at a set time, have our classes or meetings scheduled to take place at a given time… there is an endless list like this. Every aspect of life is now driven by time.

It wasn’t always like this though. Until some centuries ago, there wasn’t any need to measure time as accurately as we do today. There was basically daytime and nighttime in all the different places on Earth as the sun, moon, and the stars dictated time. But then, as the world grew smaller, and more connected with increasingly better technology, things changed.

Need for standardisation       

When rail and shipping lines started connecting the world, economic activity started requiring standardised timetables to coordinate activities. The idea for a universal time stemmed from this requirement and it was first conceived late in the 1800s.

A way to synchronise clocks across the world was first discussed in 1884 by the members who met at the International Meridian Conference in Washington D.C. While latitudes running east to west had always been measured from the equator, there was no such consensus around longitudes, or lines running north to south around our planet.

The prime meridian

It was at this conference that delegates from 25 countries chose to set the prime meridian or the zero point for longitude lines as that which passes through Greenwich, England. Time standards and time zones were built around this line, and hence came to be known as Greenwich Mean Time (GMT).

The advent of the atomic clocks after World War II enabled time to be measured with astounding accuracy in the second half of the 20th Century. These atomic clocks were able to show that Earth’s rotational period actually varied ever so slightly on an everyday basis, owing to tectonic movements, melting ice sheets, and natural oscillations in our planet’s movements.

Atomic time vs solar time

The idea behind Coordinated Universal Time or UTC (though it wasn’t yet known by that name) was thus born in the 1960s. It was a way to accommodate the differences in timekeeping that arise between atomic time and solar time. While atomic time refers to the time derived from atomic clocks and is hence extremely accurate, solar time is the time arrived at using astronomical measurements of the rotation of the Earth on its axis relative to the sun, and is hence, variable. UTC is not only kept within an exact number of seconds of International Atomic Time (TAI), but is also kept within 0.9 second of solar time or astronomical time, denoted as UT1.

Result of a compromise

UTC started being used in the 1960s, but it wasn’t until January 1, 1972 that it became the world standard for time, serving as the international basis of civil time as well as scientific time. This meant that UTC had effectively become the successor of GMT, providing for the basis of time worldwide. In case you are wondering how Coordinated Universal Time is abbreviated to UTC, then you will be pleased to learn that it is the result of a compromise. The acronym is a compromise between English and French speakers. While the English name for it, Coordinated Universal Time, would normally be abbreviated as CUT, the French name for it, Temps Universel Coordonne, would have been TUC. Instead of having it as CUT or TUC, a compromise was reached, and the acronym UTC was born.

Every time zone in the world is now given in terms of UTC. The Indian Standard Time (IST), for instance, is UTC+5:30. This means that IST is 5 hours and 30 minutes ahead of UTC. Irrespective of where you are on Earth, the time in that region can be given in terms of UTC.

What’s special about spratly Islands ?

For several years, there has been an ongoing territorial dispute among China, Taiwan, Vietnam, the Philippines, and Malaysia over the ownership of the Spratly Islands. Let us know more about these islands.

 

Spratly Islands

 The Spratly Islands consists of over 100 small islands or reefs, shoals, atolls, and small islets in the South China Sea of the Pacific Ocean. The islands are surrounded by rich fishing grounds, and gas and oil deposits.

While a great number of islands of Spratlys are now submerged, of the 12 main naturally occurring islets, the largest is the 90-acre Itu Aba. Another, called Spratly Island or Storm Island, measures 900 by 1,500 feet. Turtles and seabirds are the only wildlife on these islands. There is no permanent human habitation.

The Spratlys is significant due to their strategic location. During World War II, Japan occupied the archipelago and developed it as its submarine base. After the war, the Chinese Nationalist government established a garrison on Itu Aba and the government maintained it even after their exile to Taiwan in 1949.

When Japan renounced its claim to the islands in 1951, Taiwan, mainland China, and Vietnam declared themselves the rightful owners. The Philippines made a claim based on proximity in 1955.

The United Nations Convention on the Law of the Sea, which came into effect in the early 1980s, established the concept of exclusive economic zones (EEZ) extending 200 nautical miles from a country’s coast. This resulted in the Spratlys becoming more desirable for their potential resources.

Dispute

By the late 20th Century, Vietnam, China, Taiwan, Malaysia, and the Philippines had laid claims to the Spratlys. However, the United States, which has kept a dominant presence in the Pacific region since the early 20th Century, has not recognised the claims of any country on the Spratlys. It insisted that the Spratlys are in international waters.

Meanwhile, China has asserted that its claim to the Spratlys dates back centuries. According to the Chinese government, almost the entire South China Sea, including the Spratlys and other island groups, is within its sphere of influence. However, these claims have been disputed by others, especially the Philippines and Vietnam.

What are the interesting facts about Croatia?

Croatia is located in the northwestern part of the Balkan peninsula. The country declared its independence from Yugoslavia in 1991. However, it faced four years of war and a decade of authoritarian nationalism under President Franjo Tudjman.

History

Historically, Croatia was a bridge connecting the central European and Mediterranean worlds.

The first Croats settled here around 500 AD. From 1868 till the end of World War II, it was ruled by Hungary and then it became a part of Yugoslavia.

In the early 1990s, Communism collapsed in eastern Europe. While being part of Yugoslavia, different ethnic groups in the Croatian region began to fight for power and independence.

After Croatia declared its independence in 1991, a civil war began between the Croatians and Serbians. The war came to an end with the signing of the Dayton Agreement in December 1995.

After the fall of Communism in Croatia, the government converted the economy from the Yugoslav system of socialist self-management to market-oriented capitalism.

Geography

The country is small, crescent-shaped, and geographically diverse. It has low mountains and highlands near the Adriatic coastline.

There are flat plains near the Hungarian border. Near the mountainous regions, winters are snowy and the summers are mild. The coastal areas have hot, sunny summers and mild winters. The highest mountain here is Dinara, located in the central mountain belt.

Flora and fauna

Due to the country’s diverse geography, the flora and fauna are also varied. While on the Dalmatian coast, grapes and olives are grown, Istria is covered with firs, and Slavonia has oak forests.

The country has wolves, bears, hares, foxes, boars, wildcats, and mouflons (wild sheep). The sea life in the Adriatic includes several coral reefs, and underwater caves serve as habitats.

People

There are several ethnic groups in the country. Croats are the largest ethnic group. Serbs are the largest minority group though their population decreased after the 1990s war of independence.

The other populations include Bosnian Muslims, Hungarians, Italians, and Slovenes as well as some Albanians, Austrians, Bulgarians, Czechs, Germans, and other nationalities.

The diversity in population has influenced its cuisine. Along the coast, fish is served with blitva, which is a Swiss chard mixed with potatoes and garlic in olive oil.

The country’s literary history dates back to about 1100. The first book in the Croatian language was Hrvoje’s Missal, a liturgical text printed in 1483.

UNESCO has included several sites on its World Heritage List, such as the old city of Dubrovnik and Split, which contains the ruins of the palace of Roman emperor Diocletian.

Sports in Croatis dates back to the Roman times (medieval knights’ tournaments). The organised sport began in the country in late 19th Century, when the first sports associations were founded. In 1874, Hrvatski Sokol (Croatian Falcon) was founded. It soon became the largest organisation in the country promoting modern gymnastics and other branches of sports such as cycling, fencing, equestrianism, athletics, skating, tennis, etc.

Government

By early 2003, Slovenia became the second former Yugoslav republic to have applied for membership in the European Union (EU). On July 1, 2013, the country became the 28th member state of the EU.

The President is elected by a popular vote to a five-year term. However, his role is mainly ceremonial. Though the President appoints the Prime Minister, the parliament approves the nomination.

Did you know Norway is the natural habitat of reindeer?

Or that the animals are perfectly adapted to life in the Arctic Circle? Here is an account of a wildlife conservationist that throws light on the snow-covered landscape and the animals owned and cared for by the traditional Sami people.

Many years ago, I joined a team of wildlife experts and travelled to Norway, near the Arctic Circle. This is the natural habitat of reindeer. Apart from wild reindeer or caribou, there were hundreds of almost tame ones that were herded by a traditional community called the Sami.

It was the most amazing snow-covered landscape-the entire ground was white as far as the eye could see. It was freezing cold and though all of us wore several layers of sweaters and jackets, our hosts gave each of us a full snowsuit with a hood, snow boots and thick gloves.

The reindeer herd was out grazing in a pasture far away. We travelled in motorised sleds to see them. It was a thrilling but scary ride. The young Sami man driving the vehicle took us at breakneck speed over the powdery snow, swerving expertly between trees and almost flying up and down slopes. I held on tight, grateful for the snowsuit that protected me from the chilly wind and icy spray of snow that blew up in our wake.

From a distance, the reindeer looked like dark shadows against the almost blinding whiteness of the snow-covered open meadow. As we approached, they continued to graze peacefully. They were semi-domesticated, allowed to roam free without being tied up or confined, yet owned and cared for by the Sami families. There were about a hundred reindeer in the herd with many fawns. The adults looked majestic with their crowns of beautiful branching antlers.

Cone-like tents or Lavvus

Sami families move along with their herds and camp in huge inverted cone-like tents called ‘lavvu’ wherever they want to stop. Reindeer are big animals-almost like horses. Both males and females have antlers and they are sturdy and strong with long legs to help them walk in deep snow.

Reindeer have two layers of fur to keep out the cold-a fluffy inner layer and a hairier outer one. Even their hooves are hard and horny to enable them to walk easily on ice and snow.

Interestingly, the fawns are born in winter. They have extra fat in their bodies which insulates them against the intense cold.

In short, they are perfectly adapted to life in the Arctic Circle, where the temperature is below zero for much of the year.

Looking for lichen

I wondered what they were eating, because there was not a blade of grass or leafy bush to be seen anywhere! Then I noticed the big reindeer were digging the ground with their forelegs. They were looking for lichen or ‘reindeer moss’ growing on the rocks underneath. This was the only food available to them in winter. Lichens are a combination of a fungus and an alga. Usually they are found on the bark of trees or on stones and rocks. The reindeer use their sharp hooves to scrape it off from rocks and boulders that lie beneath the snow.

When the snow thaws in summer, the ground becomes marshy and spongy, so the reindeer’s hooves develop pads to help them to walk and run. In the few months of the short Arctic summer, grasses and plants grow quickly and abundantly. The reindeer then feed on the lush, fresh vegetation till winter returns.

Dressed in woollen fabric

After showing us the herd, our host took us to a group of tents belonging to Sami families. A few women and men came out to greet us, dressed in colourful red and blue traditional coats made of embroidered woollen fabric and wearing elaborate reindeer fur hats and thick boots also made of fur. They invited us to have dinner and spend the night in their home which was a typical lavvu. The snow all around was so soft and deep that I sank up to the knees with every step. I envied the reindeers long, strong legs!

In the centre of the lavvu, I was surprised to find a log fire burning with a huge pot of steaming stew on it! After a meal of delicious stew, bread and jam served by our hosts. I crawled into a sleeping bag as near the glowing fire as possible. I was still wearing the full snowsuit with its fur-lined hood to cover my head, as well as thick gloves and wool socks, yet the bitter cold had me shivering and sleepless all night. I was filled with admiration for the Sami, as well as for the reindeer, who had both adapted to such a harsh climate.

Japan: Where tradition meets modernity

Sushi, ikebana, cherry blossoms, haiku, sumo and more… Japan is a rich showcase of heritage. But hold on, modern Japan reflects Western cultural influences too.

Ranu Joardar

Japan, a string of islands, has achieved remarkable success since the devastating Second World War. It is now the world’s third-largest economy, a major aid donor, and plays a major role in the Asia-Pacific region. Let us know more about the country.

History

Though it remains unknown when humans first settled on the Japan archipelago, the excavations since the Second World War have unearthed a wide variety of Paleolithic tools. Japan’s first emperor Jimmu Tenno came to power in 660 BC. Emperors continued to rule the country till the 12th Century AD when military rulers (shoguns) took over.

Europeans came to the country in 1543, introducing guns and Christianity. In 1635, shoguns banned the entry of foreigners, and citizens were not allowed to travel abroad. The isolation continued for 200 years until the shoguns were overthrown in 1868. This political revolution that brought an end to the military government was known as the Meiji Restoration. During the First World War, Japan fought alongside the U.S. After the bombing of the United States Navy fleet at Pearl Harbor in Hawaii by Japan on December 7, 1941, the U.S. joined the Second World War. From 1941-1945, Japan’s military leaders fought against the U.S. and the Allied forces. In 1945, the U.S. army dropped atomic bombs on the Japanese cities of Hiroshima and Nagasaki, killing about 1,15,000 people. Japan surrendered a few days later.

Geography

Japan consists of a string of islands in a northeast-southwest arc that stretches for about 2,400 km in the western North Pacific Ocean. Though there are numerous small islands, the four main islands from north to south are – Hokkaido, Honshu, Shikoku, and Kyushu. Honshu is the largest island of the four. The national capital, Tokyo, in Honshu is one of the world’s most populous cities.

The country’s four-fifth portion of land is covered with mountains. It has about 200 volcanoes, 60 of which are active. Its highest peak is Mount Fuji, a dormant volcano since its last eruption in 1707. The mountain is part of the Fuji-Hakone-Izu National Park and is at the centre of a UNESCO World Heritage site designated in 2013.

The country is extremely prone to earthquakes as tectonic plates that form the Earth’s crust meet nearby and they often move against each other. Every year, the country faces about 1,000 tremors, most of them minor. The major earthquakes in the country included the Tokyo-Yokohama in 1923 and Kobe in 1995. In 2011, the country witnessed a major earthquake that caused widespread damage on land and initiated a series of large tsunami waves. The tsunami caused the Fukushima nuclear accident, the second worst nuclear accident in the history of nuclear power generation. Some rivers flowing from the volcanic areas of northeastern Honshu are acidic and hence cannot be used for irrigation and other purposes.

Flora and fauna

Most of the original vegetation in Japan has been replaced by agriculture or foreign species. The Ryukyu and Bonin archipelagoes are covered by semitropical rainforest and have various kinds of mulberries, camphor, oaks, and ferns (including tree ferns). The cherry tree is one of the symbols of Japan.

According to the ancient Shinto religion, features like mountains and forests have their own spirits (souls).

The mammals in Japan are mostly found in the remote, heavily forested mountain regions. These animals include bears, wild boars, raccoon dogs (tanuki), foxes, deer (including sikas), antelope, hares, and weasels. The Japanese macaque or snow monkeys are important figures in myths and folktales. For instance, they are represented in the Buddhist adage “See no evil, hear no evil, speak no evil.”

People

The Japanese are known as hardworking people. At a very early age, children are taught self-discipline, respect, and cooperation.

The Japanese language is similar to Korean, though the Vocabularies are different. According to some linguists, Japanese contains some elements of the Southeast Asian languages. Earlier, the Japanese had no written form. The Japanese language was enriched with the introduction of the Chinese writing system and Chinese literature around the 4th Century AD.

One of the well-known forms of Japanese poetry is Haiku, which first emerged in Japanese literature during the 17th Century. It is an unrhymed poetic form of 17 syllables.

The native religion of Japan, Shinto, coexists with various sects of Buddhism, Christianity, and some ancient shamanistic practices, as well as a number of new religions that emerged since the 19th Century. Though children usually do not receive formal religious training, many Japanese homes have a Buddhist altar where various rituals are held to commemorate deceased family members.

Modern Japanese culture is a mix of both East and West influences. It has familiar elements of the West and also powerful and distinctive traditional cultural aesthetic. Western art forms have been embraced by the Japanese. The Japanese are one of the most literate peoples in the world.

Japanese food mostly contains rice, fish, and vegetables. Their cuisine is often served raw or only lightly cooked but is famous for its subtle and delicate flavours. Their best known dish sushi is cooked vinegared rice served with a variety of vegetables, sashimi (raw seafood), and egg garnish, and formed into various shapes. Another popular part of Japanese food is green tea, which is cultivated on or near the slopes of Mount Fuji in Shizuoka prefecture.

Due to their healthy diet, the Japanese people live a very long life (longer than any other people in the world). In March this year, the world’s oldest person Kane Tanaka passed away at the age of 119.

Japan has a rich tradition of arts such as tea ceremony, calligraphy, ikebana (flower arranging), gardening, architecture, painting, and sculpture. Their performing arts are distinguished by their mix of music, dance, and drama, rooted in different eras of the past.

Japan is home to over a dozen UNESCO World Heritage sites. Historic monuments like Kyoto and Nara (designated in 1993 and 1998 respectively) reflect the country’s rich tradition. Meanwhile, the Atomic Bomb Dome at Hiroshima and the silver-mining area in Honshu are part of recent history.

Though several sports are played in Japan, its traditional sport is sumo (its origins date back to the 8th Century). Six major professional tournaments are held annually and they are avidly followed throughout the country.

Government

Japan is one of the world’s most successful democracies and largest economies. Its constitution was formed in 1946 and came into force in 1947, which superseded the 1889 Meiji Constitution. Interestingly, Article 9 of the constitution states that Japan has renounced war forever as a sovereign right of the nation. This clause had been under much debate.

Though the country still has an emperor, he is only the symbol of the state and of the unity of the people. His major role includes appointing the Prime Minister (who is first designated by the Diet, the national legislature) and appointing the chief justice of the Supreme Court.

In 2019, the father of current emperor Naruhito, Emperor Akihito, became the country’s first monarch to step down from the Chrysanthemum Throne in two centuries.

What is the first Wild River National Park in Europe?

Just a few months ago, the Albanian government declared the river Vjosa and its tributaries a national park. With that it became Europe’s first wild river national park, and it was called a “historic moment. Why so? Come, let’s find out.

Claimed to be “one of the last wild rivers in Europe”, Vjosa runs 270 km from Greece to Albania, and then joins the Adriatic Sea. It is said that the river became part of this significant move after nearly a decade-long campaign by environmental NGOS in the region, now placing the country “at the forefront of river protection”. Unlike many rivers in central Europe, Vjosa flows freely and is wild, in that, it is largely untouched by infrastructure projects. This makes it similar to a natural wildlife habitat on land, without any human interference. By becoming a national park, it can be compared to protected wildlife areas on land. The national park covers over 32,000 acres, including the 190-km-long Albanian part of the river, where more than 60,000 people live.

But why it truly needs to be protected is because of this – “The river and its surrounding areas are ecosystems of substantial biodiversity and home to over 1,100 species of animals. Two of the plant species and 13 of the animal species are assessed as globally threatened by the International Union for Conservation of Nature” (IUCN). Not just that. As a national park, the focus will be on concerns such as “water and land pollution, waste management”, etc. Further, it “will create economic opportunities for local communities through responsible tourism”.

It is noteworthy that the Albanian government ended plans to have eight hydropower stations on the river and its tributaries, which could “have caused serious damage to the river’.

Meanwhile, a half-built hydropower station on the river and a new, multimillion-euro international airport being built where Vjosa flows into the Adriatic are concerns, especially since the latter could cause “irreparable damage to the fragile ecosystems of protected lagoons that host flamingos, pelicans and millions of other migratory birds”.

While there are marine reserves globally and rivers flowing within national parks, instances of a wild river itself as a national park are not as common. As countries globally battle climate change and many other challenges, Albania’s move is perhaps a crucial necessity worthy of emulation.
