Evolution

When you think of evolution the first name that comes to one’s mind is that of Charles Darwin. However, the fact is that he was not the first person to put forward the idea of evolution. Lamarck had suggested it earlier but the concept was not popular. In fact zoology professor Robert Grant lost his job because he supported Lamarck theory! An anonymous work titled, ‘The Vestiges of creation’ was ridiculed. It was Charles Darwin who first made the theory acceptable and he was able to do so because he supported it with a huge amount of evidence. Darwin, an English naturalist put forward his theory in a book titled ‘On the origin of the species’. He established that all species descended from common ancestors and that the different species evolved through a process he called natural selection. Darwin’s theory gained acceptance because it was able to explain the diversity of life.


Ramapithecus belongs to an extent group of primates that lived from about 12 to 14 million years ago. Fossils of Ramapithecus were discovered in India and Africa beginning in 1932. Fossil evidence suggested that it had a short face, heavy jaws and enamelled teeth like hominids. Its importance lies in the fact that it was regarded as a possible ancestor of Australopithecus and therefore of modern humans. Later for sale finds indicated that Ramapithecus was more closely related to the orangutan and Ramapithecus is now regarded by many as a member of a group known as Sivapithecus.


It has been long known that humans share a common ancestor with apes but it was only in the last 30 years that techniques for develop to provide strong evidence in support of the theory that humans are more closely related to chimpanzees than they are to gorillas orangutans or Gibbons. The DNA of a chimpanzee is 98% identical to that of a human being. However our bodies adapted for walking on 2 legs. This is possible because the lower portion of the human body evolved to facilitate load bearing and balancing while walking upright. Chimpanzees not only share most of our genes they seem to be able to handle tools and they are able to grasp language pretty well too. Now researchers have found that we share a similar brain pattern when communicating. But in spite of these similarities there are clear differences in body structure intellect and behaviour.


Australopithecus was an early hominid which is now extinct. Fossil evidence suggests that these individuals lived from approximately 4- 2 million years ago after evolving on the continent of Africa. Sense the fossils were recovered from south Africa they were called south African man apes or australopithecines. Australopithecines are believed to have been around 1 to 1.5 metre tall and probably fed on leaves fruits and the remaining of dead animals. Their brains were larger than those of apes but smaller than human brains while their teeth would like human teeth it is believed that Australopithecus eventually evolved into modern humans.


Neanderthal man first appeared in Africa about 200,000 years ago and migrated to the rest of the world around 100,000 years ago. The name Neanderthal comes from Neander valley where an early skull was found. Neanderthals would different from other species of early man. They were much taller and very strong for stop the brains were actually larger than ours are today. They were marvellous hunters. They often used caves as their homes. They were adept at fire making and probably cooked their food routinely. Neanderthals buried their dead. The Neanderthals died out by around 30,000 BC.
Cro-Magnon man lived some 40,000 -10,000 years ago. Their remains were first found in France in 1868 and then throughout other parts of Europe.

Cro-Magnon man was anatomically identical to modern humans and deferred significantly from Neanderthal man who disappeared in the fossil record shortly after Cro-Magnons appearance. Cromagnon man was tall and had an erect posture. He had a prominent chin a surprising forehead and skull shaped like hours. These man was killed hunters toolmakers and artists. Cro-Magnon man was a true human and looked just like us. He is represented by the remains of 5 individuals found in March 18683 adult males one adult female and one child.


•First family.
In 1975 Donald Johansson discovered the remains of at least 13 individuals of all ages at her there in Ethiopia. The sizes of the specimens varied greatly and Johansson believed that they all belong to a single species Australopithecus afarensis in which men were much larger than the females.

Paradox…

A logically self contradicting statement is a paradox. Also known as antinomy. You can say it is a sentence that runs contrary to one’s expectations. Actually it’s just a smart mess. It does have valid reasoning but leads to a self contradictory or a logically unacceptable conclusion. It might seem absurd but is kind of the ultimate truth. That’s what makes it all the more interesting.

Let’s see some of the many interesting paradoxes that exist and try to understand them.

•Achilles and the tortoise 🐢🏃

One of the “greatest” there is. It was put forward by the Greek philosopher Zeno of Elea in the 5th century BC. It so happens that the great hero Achilles challenges a tortoise to a footrace. Being the hero that he is, he allows the tortoise a headstart of 500m. No doubt, when the race starts, Achilles is at a must faster speed than the tortoise such that by the time he has reached the 500m mark, the tortoise has only walked 50m further than him. When he has reached 555m mark, the tortoise has walked another 0.5m, then 0.25m, then 0.125 m and so on. It is a chain of such infinite small distances with the tortoise always moving forwards while Achilles always has to catch up. Now, logically, Achilles can never overtake the tortoise. Except, of course, intuitively he can overtake.

Don’t think of it in terms of distances and races but rather as an example of how finite value can always be divided an infinite number of times, no matter how small its divisions might become!

•Birthday paradox 🎉🎂

This is personal favourite. It is maths based by the way. Probability to be specific. You have already heard of this probably. It goes like this that in a group of 23 randomly selected people there is a 50% chance two of their birthdays match. Interesting? Wait. In a group of 367 random people there is a 100% possibility atleast two of their birthdays match. Sounds like such a small number. It counts as a paradox because we can’t handle such numbers.

•Crocodile paradox 🐊

A crocodile snatches a young boy from the riverbank. Pretty common situation right? Anyways, his mother pleads with the crocodile to return the boy. The crocodile being in a fun mood, wants the mother to guess if he will return the boy or not. Takes one guess to get the boy out safely. It looks simple – the mother guesses he will return the boy, if she is right she gets the boy, if she is wrong, the crocodile gets the boy. If she answers that the crocodile will not return him, however, we end up with a paradox!

If she is right and the crocodile never intended to return her child, then the crocodile has to return him but in doing so breaks his word and contradicts the mother’s answer. And if she is indeed wrong and the crocodile did intended to return the boy, the crocodile must then keep him even though he intended not to, thereby also breaking his word. It’s a brain twisting dilemma.

•Paradox of fiction 🎟️📕

Are you fixated with the harry potter characters? You ofcourse have a crush on the Marvel or DC comic characters. Oh or did you cry when Augustus died?

So here is the paradox. Point 1 People have emotional responses to characters, objects, events etc. which are fictitious. Point 2 In order to be emotionally moved, we must believe that these characters or events by no way exists in real. Point 3 No person who takes characters to be fictional at the same time believes that they are real. All three of these points one at a time can be true. If any two points are considered to be true then the third must be false or else produce a contradiction. There exist various proposed solutions to this paradox such as pretend theory or thought theory or illusion theory.

•The card paradox 🃏

This one is a little bit similar to the crocodile paradox. A little. So I say we have a card with us. On one side, the front side, “the sentence on the other side of this card is TRUE” written on it. You flip and “the sentence on the other side of this card is FALSE”. You take one as true and it leads to a paradox!

Anniversaries (as of 2019)

150th birth anniversary

•Mahatma Gandhi, the father of our nation is an inspiring person, who shaped world history. Gandhiji stands out among the great men of the world as a symbol of non violent resistance to political and social repression. Mohandas Karamchand Gandhi was born on October 2nd, 1869 in Gujarat. He became the leader of a movement that attracted millions in the struggle for freedom. He was strong advocate of non-violence. India got freedom on August 15th, 1947. Gandhiji was assassinated on January 30th, 1948.

100th birth anniversary

• The year 2019 marks the 100th birth anniversary of Dr. Vikram Sarabhai, the father of the Indian space programme. He was born on 12th August, 1919. Dr. Sarabhai has put India on the international map in the field of space research. In 1962, he became chairman of the Indian National committee for space research. The establishment of the Indian space research organisation, also known as ISRO, was one of his greatest achievements. Dr. Sarabhai died on 30th December 1971.

500th death anniversary

• Leonardo da Vinci was perhaps the most widely talented person ever to have lived. He was a consummate painter and sculptor, a great inventor, military engineer, scientist, botanist and mathematician! He lived during the Renaissance in Italy and while working in Milan as an artist, he began writing texts for his students and apprentices. His notebooks covered more than 1000 pages of observations and illustrations. They remained unpublished for more than a century and were printed only after his death. He was born on April 15th 1452 and died on May 2nd 1519.

150th anniversary

• The period table gives us information about element symbols and atomic weights. It brings order to information about the chemical elements and helps chemists to understand why elements react as they do. The milestone in the development of the periodic table was set by the Russian chemist Dmitri Mendeleev in 1869, who is acknowledged as the ‘father’ of periodic table though the title is also claimed by the German scientist Lothar Meyer. Today, the periodic table organizes the elements by order of increasing atomic number.

150th year of publication

• 2019 marks the 150th year of one of the greatest novels ever written – Leo Tolstoy’s ‘War and Peace’. This classic work from Russia was first published in the book form in 1869. Tolstoy took almost 7 years to finish this epic work and a Russian magazine named ‘Messenger’ serialised some portions of it during 1865-67. But the full novel came out as a book only in 1869. The story woven around Napoleon’s invasion of Russia covers a period of over 15 years. The unique literary style and the historical context make ‘War and Peace’ a monumental work.

125th year of publication

• Is there anyone who isn’t familiar with the famous character ‘Mowgli’? Hopefully none. The main character of the evergreen ‘Jungle Book’, a collection of stories written by Rudyard Kipling is a huge part of our childhood. ‘The Jungle Book’ was first published in 1894.

100th anniversary

• The Jallianwala Bagh massacre was a turning point in our freedom movement. The British troops under the command of Colonel Reginald Dyer, opened fire on unarmed Indians on 13th April 1919. This event took place in the heart of Amritsar. Hundreds were killed and thousands injured. This was followed by widespread protests across a grieving country. Many Indians became convienced that the British had to be paid back in their own coin that violence has to be met with violence. The 100th anniversary of that cruel incident fell last year.

300th year of publication

• Daniel Defoe’s ‘Robinson Crusoe’ has fascinated readers around the world for the last 300 years. Daniel Defoe was an English writer, famous for his novel Robinson Crusoe that was published in 1791. One reason for it’s popularity is that it us packed with excitement and adventure, with sailing ships, stormy seas and guns. Without doubt, Defoe’s ‘Robinson Crusoe’ established a realistic style of fiction and set the tone for modern novels.

Small yet distinct

The word ‘country’ makes one think of a large land mass. However, not every country is huge. There are some countries that are really small in size. They are so tiny, that some of them can even be covered by foot! Some of these countries can fit entirely within the city of another country. The smallest country in the world, the Vatican City, for example, can fit into the city of Rome, capital of Italy. Many of these countries are only small in size. With their wealth and natural resources, they can even compete with any of the larger countries. So, here’s a showcase of some of the small, yet distinct countries.

• Vatican City

Vatican City is the world’s smallest fully independent nation state. It is also the smallest by population. Situated on the western bank of the Tiber river, the Vatican City’s 3.2 kilometre border is landlocked by Italy. The Vatican City has served as the official home of the pope of the Catholic church since 1377. However, Vatican City was not declared an independent state until the Lateran treaty of 1929 which created the independent state of Vatican City for the Catholic church. Today nearly 75% of the Vatican’s citizens are members of the clergy. Along with the centuries old buildings and gardens the Vatican maintains its own banking and telephone systems post office pharmacy newspaper and radio and television stations. Its 600 citizens include the members of the Swiss guard a security detail charged with protecting the Pope since 1506. The most significant building in Vatican City is Saint Peter’s Basilica. It is the Italian language that is used by most of those located within the state however the official documents are written in Latin.

• South Korea

Compared to the giants of Asia like India and China, South Korea is much smaller in size. Its total area is 100,032 square kilometres. South Korea has one pf the most homogeneous populations in the world which are thought to be descended from several Mongol tribes that migrated from central Asia. Tourism is a fast growing industry in South Korea.

• Portugal

Portugal is a sovereign state in Western Europe. It comprises of the continental part of Portugal on the western coast of the Iberian Peninsula and the small archipelagos of Madeira and the Azores in the Atlantic Ocean.

• Hungary

The name “Hungary” may very well come from the medieval Latin word ‘Hungaria’ which translates as “Land of Huns”. Another source states that the name is derived from the Turkish words on ‘Ogur’ meaning ‘ten arrows’ or ‘ten people’

• UAE

The United Arab Emirates is a constitutional federation of seven Emirates; Abu Dhabi, Dubai, Sharjah, Ajman, Umm al-Quwain, Ras al-Khaimah and Fujairah. The federation was formally established on 2nd December, 1971. The UAE’s oil reserves are the seventh largest in the world while its natural gas reserves are the worlds seventeen largest. The Dubai police fleet includes Lamborghini, a Ferrari and a Bentley. This is to allow them to catch speeders who can outrun other cars.

• Dominican republic

The island of Hispaniola, the second largest island of the Antilles in the Caribbean contains two separate countries, the Dominican republic and Haiti. The Dominican republic is the only country in the world to have an image of the Holy Bible on its national flag.

• Panama • Georgia • Ireland • Iceland • Sri Lanka • Costa Rica • Bhutan • Switzerland • Belgium • Israel • Fiji • Qatar • Jamaica • Singapore • Maldives …to name a few others.

Mysteries (II)

Part one was : http://eduindexnews.com/2020/09/14/bermuda-triangle-and-other-mysteries/

• Indian rope trick

India is a land of countless mysteries that have puzzled the rest of the world. Perhaps the most enduring of these mysteries is that of the ‘Indian rope trick’. In the classic version of Indian rope trick, a rope is thrown into the air where it remains rigid. A young boy then climbs the rope, only to disappear at the top. The performer quickly follows him only to disappear when he reaches the top of the vertical rope! Shortly after, pieces of the boy’s body fall from the sky and land on the ground at the bottom of the rope. A few seconds later, the performer is seen climbing down the rope with a blood stained knife in his hand. On reaching firm ground, the performer utters a magic word and the rope falls limp to the ground. He then gathers up the pieces of the boy’s body and bundles them under a sheet. Within seconds, the sheet is lifted and the boy appears completely whole and unharmed! Travellers to India have described this amazing trick for over 600 years, but there is considerable doubt as to whether the trick is fact or fantasy.

• Shroud of Turin

The shroud of Turin is reputedly the cloth in which Jesus Christ was wrapped and buried. The shroud is 4.34 meters long and it bears the image of a man with wounds similar to those suffered by Jesus Christ. The shroud is unquestionably old. Its history is known from the year 1357, when it surfaced in the tiny village of Lirey, France. Today, it is kept in a silver chest in the Cathedral of Saint John, the Baptist in Turin, Italy, where it has been since 1578.

Does the shroud really show the face of Jesus? No one really knows. Although, many scientists have expressed doubts about the accuracy of the image, millions believe it to be divine and it has been a religious relic since the middle ages.

• Loch Ness monster

As far back as the 17th century, people have reported seeing a monster in the Loch Ness in Scotland. Loch means lake in Scotland. This is the largest freshwater lake in the UK. But, rather than being known for its size, it is famous for the mysterious legend of the Loch Ness monster or Nessie.

For thousands of years, people have reported catching glimpse of a huge creature. This creature is said to have a small head, a long neck and an immense body with flippers. Some people have shared photos they claim to have taken of this huge creature. The legend is so great that even scientists have been intrigued and many have conducted experiments and come up with theories to try and explain what people could be witnessing.

One explanation is that the monster could be a prehistoric creature called plesiosaur, an animal that has been considered to be extinct. Maybe one of these creatures managed to survive in the Loch Ness Lake, who knows?

Curiosity (science)

• Why do we wake up from sleep?

Sleep is essential to give the brain and nerves some rest. While we sleep, our bodies too, get a chance to recover from the fatigue caused by daily activities. When we are well rested, both physically and mentally, we wake up. Sometimes, we wake up because we feel cold or hungry or because a bad dream has made us afraid.

To sum up, we all have an internal body clock that tells our brain to wake our bodies up after a certain amount of time. However, some things or situations such as noise, temperature in the room or sunshine interrupt our sleep and wake us up too.

• Why doesn’t glue stick to the insides of the bottle?

The regular white glue that we use is made up of a variety of chemicals that are either sticky or stretchy. White glue also contains water. Water acts as a solvent that keeps the glue liquid until you want it to stick. When you put glue on a piece of paper, the water in it is exposed to air. The water eventually evaporates and as it does so, the glue dries and hardens and holds the things that need to be glued, stuck together.

When the glue is inside the bottle, there’s not enough air inside the bottle to cause the water to evaporate to make the glue sticky. The bottle protects the glue from the air and keeps the glue runny. This is also why if you’ve ever left the top off a glue bottle for a while, the next time you try to use the glue, it would have dried up.

• Why do the lights of a distant town appear to twinkle?

When you are traveling at night, the lights of towns in the distance appear to twinkle. This is because of the constant movement of air above towns. The air above towns is warm, as a result of the heat given off from buildings. Warm air keeps moving up to be replaced by cold air which then gets heated and rises. This constant movement of air is known as turbulence.

When we are near a town or in it, we don’t notice the turbulence because it is quite small and the lights are nearly. However, when we are some distance away, the lights are far away too. They appear as only pinpricks. The warm and cold air that make up the turbulence above the town have different densities and light passing through the layers is bent at different angles because of this difference. As a result it appears as though the lights of the distant town are twinkling.

• Why do clouds have different shapes?

Clouds are made up of tiny droplets of water vapour or ice particles or both. The shape of the cloud depends on its height and temperature. Cumuliform clouds are shaped liked mushrooms and are formed when rising warm air cools as it goes up. Stratiform clouds come in flat, dull layers and are formed when air sinks in a high pressure area, creating a layer of cold air near the ground that doesn’t rise or rises only very slowly. Cirriform clouds are clouds that have risen on a front or tropical cyclone and frozen into ice crystals at very high altitude. They look like thin hair. The shape of cloud also depends on the time of the day.

Towards evening, clouds tend to be thinner and flatter than during daytime. Changes in wind patterns also change the shapes of cloud.

Curiosity (animals)

• Why don’t woodpeckers get a headache?

Have you ever seen woodpeckers striking trees with its long beaks? Woodpeckers hit the trees 20 times per second. Yet they don’t get a headache or any other head injury. The reason for thus is that woodpeckers are born with a helmet for the brain, which is formed of strong, thick muscles and sponge like bones in their skull. A woodpecker’s body too is specially designed to absorb the impact of the hit.

A millisecond before a woodpecker’s bill strikes on a tree dense muscles in the neck contract. Some of the force radiates down the neck muscles and protect the skull from a huge impact. A compressible bone in the skull offers a cushion effect too.

• Why aren’t spiders caught in their own webs?

Spiders spin their webs in a circular pattern that is spotted with sticky glue. When an insect brushes against these drops – each thread can carry several dozen per millimetre – it gets stuck and the spider rushes over to inject it with venom or cocoon it in silk. The question of course is how does the spider escape its own glue tracks? The answer lies in the fact is that the web is the spider’s home and it knows its way around the glue traps. There are some threads in the web that have no glue on them and the spider is careful to move only on these threads. It is also believed that spiders use an oily coating on their legs to protect themselves from getting stuck in their own webs!

Colourless rainbow

There are some rainbows that are colourless. They are called fogbows and are formed when the sun shines through a fog. The drops of water in the fog are too small to split up light into it’s different colours, so the fogbow is white in colour.

• What do we know about left handed animals?

Most people are right handed, though about one in ten among us is left handed. Animals like chimps, hump back whales and even toads favour one hand, paw, claw or fin over the other. Chimpanzees use both hands with ease, but have a preference for the right hand. Toads also prefer their right side to perform differ functions. Polar bears on the other hand, are left handed.

Some species of parrot such as the sulphur- crested cockatoo are entirely left handed, while others, including the king parrot are mainly right handed. The majority of parrots – including the budgie, galah and rainbow lorikeet use both claws comfortably. Female cats are more inclined to be right handed while male cats favour their left paws. The same is true for dogs. Interestingly, dogs wag their tails to the right when relaxed and to the left when agitated!

Vaccination and COVID-19

How long has it been since we went to school met our friends or had a family dinner at some restaurant? Since March 2020, we have all been advised to stay home and sanitise ourselves in order to stay safe. Sanitizers and masks have been added to our daily use products, all because of one tiny yet dangerous virus Covid-19!

The world is now waiting anxiously for a vaccine against this dreaded virus. Researchers around the world are working round the clock to develop vaccines to combat the pandemic. Currently, more than 165 vaccines against the corona virus are under process and 27 vaccines are undergoing human trials. Vaccines typically require years of research and testing before reaching the clinic. Today, scientists all over the world are racing to produce a safe and effective vaccine by next year.

• When did the efforts start

Efforts to make a successful Covid-19 vaccine began in January 2020 with the deciphering of the SARS-CoV -2 genome. The first vaccine safety trials in humans started in March but the road ahead remains uncertain. Some trials will fail and others may end without a clear result. But a few may succeed in stimulating the immune system to produce effective antibodies against the virus.

• India and vaccine against Covid-19

Like many other countries, India too is immersed in the efforts to develop successful vaccines to counter Covid-19. Thirty different Indian companies are trying to produce a vaccine to fight the infection. 7 out of these have received approval from the World Health Organization. These vaccines are in different stages of testing and clinical trials now.

COVAXIN

COVAXIN is developed by Hyderabad based Bharat Biotech International Limited in collaboration with ICMR and NIV, Pune. This is the first vaccine from India to get regulatory approval. The vaccine makes us an inactive version of a virus to spike up production of antibodies in the host body. It recently initiated Phase I and Phase II of clinical testing.

ZyCoV-D

ZyCoV-D is being developed by Zydus Cadila based in Ahmedabad. The Phase I trials of the vaccine have already begun. Extensive research was done regarding the same in collaboration with medical labs in Europe and US.

• Russia and vaccine against Covid-19

Russia is one of the countries worst affected by Covid-19. The country has been pushing extensively for a Covid-19 vaccine for quite some time now; Russia too is a part of the race to produce the world’s first Covid vaccine. It is possible that Russia would be ready with its first domestic corona virus vaccine soon. The clinical trials were conducted by the Gamaleya National Research centre of Epidemiology and microbiology. There seem to be no reports of side effects on the volunteers. All the participants showed immunity and the country is planning for the serial production of the vaccine by September. By the beginning of next year, Russia hopes to manufacture several million doses of corona virus vaccines per month.

• Oxford University’s efforts to develop a vaccine

The university of Oxford has partnered with AstraZeneca, a British-Swedish pharmaceutical company to develop an adenovirus vector vaccine to combat Covid-19. The vaccine prototype is currently in Phase III of testing. Trials of the vaccine developed by Oxford University show it can trigger an immune response. The vaccine which has so far been found to be safe and effective is expected to be made available for the masses by the end of 2020. This vaccine would also be the first such vaccine to have a large scale testing in India. The observatory data for this vaccine is expected to be available by November this year. The company has tied up with Pune based serum institute of India to mass produce the vaccine once the company gets required approvals and licensing from medical boards.

• Some methods used to make vaccines for Covid-19

Different scientists across the world try different techniques and formulas to develop vaccines. The Oxford researchers have put small sections of the corona virus genetic code into a harmless virus that infects chimpanzees. They appear to have developed a safe virus that looks enough like the corona virus to produce an immune system. Some other scientists have used pieces of raw genetic code, either DNA or RNA. When these are injected into the body it would start producing bits of viral proteins which the immune system can learn to fight. There is also work on corona virus vaccines called ‘plug and play’ vaccines. This method is new and less tested.

Beverages from scratch…

• Wine

Wine is as old as civilization itself and it has a significant place in many ancient cultures. Many experts agree that wine probably dates to 6000 B.C., to Mesopotamia where wild vines grew in abundance. The popularity of wine eventually spread to Egypt, along the Nile Delta. Wine came to Europe with the spread of the Greek civilization around 1600 B.C. It was an important article of Greek commerce and Greek doctors including Hippocrates, were the among the first to prescribe it. The Greeks also learned to add herbs and spices to mask spoilage.

Starting about 1,000 B.C., the Romans made major contributions in classifying grape varieties and colours, observing and charting ripening characteristics, and popularizing the growing of vines and manufacturing of wines. As time progressed, the wealthy enjoyed the fruits of the vine. After the collapse of the Roman Empire, Europe’s wine industry was saved by the church as monks planted vines to provide wine for Mass. Before long, France emerged as a leader, with some of the world’s finest wines.

Did you know that an ancient Persian fable credits a lady of the court with the discovery of wine? This princess lost favour with the king and attempted to poison herself by eating some table grapes that had ‘spoiled’ in a jar. She became intoxicated and fell asleep. When she awoke, she found that she felt much more relaxed and stress free and wine was discovered!

• Coffee

According to legend, an Arabian shepherd named Kaldi found his goats dancing joyously around a dark green leafed shrub with bright red cherries in the southern tip of the Arabian Peninsula. Kaldi soon determined that it was the cherries on the shrub that were making them act this way. After trying the cherries himself, he learned of their powerful effect. These were coffee berries and monks at a local monastery started using a drink made of these berries to stay awake during extended hours of prayer. And so, coffee was born.

The ancient Ethiopians made balls of crushed coffee beans and fat to give them energy during long journeys. The coffee we are familiar with originated in Arabia, where roasted beans were first brewed around A.D. 1,000. Later, coffee was brought to the rest of Asia from where it was taken to Europe by a merchant from Venice.

Did you know that the name coffee is derived from the Arabic term ‘gahwa’ which means ‘that which prevents sleep’?

• Tea

Did you know that tea is 5000 years old? According to legend, it was discovered in 2737 B.C., by a Chinese emperor when some tea leaves accidently blew into a pot of boiling water. The emperor was interested in the new liquid, drank some, found it very refreshing, and tea was created!

Tea consumption spread throughout Chinese society reaching into every strata. In time, drinking tea became part of the social and cultural life in the far East and India. Tea was introduced to India by the silk caravans travelling from the Orient to Europe. It was a Buddhist priest who brought the first tea seeds from China to Japan. In Japan, tea received almost instant imperial sponsorship, and spread rapidly from the royal court and monasteries to the other sections of Japanese society. Dutch traders and Portuguese missionaries brought tea into Europe and tea became an extremely fashionable drink in the court of Charles II of England. Tea has played a very important role in the history of England for it brought fortune to the British empire and at the same time, it was a tax levied on tea that led to the loss of her colonies in the New World.

Today, tea is grown on tea estates, and 70% of the tea we drink is grown in Sri Lanka, India, Indonesia, Kenya, Argentina and China. Amazing, we drink virtually the same tea today that the Chinese emperor drank the day he discovered it!

• Carbonated soft drinks

Do you love fizzy soft drinks? Well, even the ancient Romans loved to drink the bubbling waters of mineral springs and they believed that this water was very good for health as well. Later, scientists discovered that it was the carbon dioxide in the water that caused these bubbles and tried to find a way to introduce this gas into plain water to give the same effect. Thanks to the efforts of such scientists as Joseph Riestley and John Nooth, this feat was accomplished and carbonated water was available for sale by the end of the 1700.

The next step was to flavour this sparkling water. In 1784, citric acid was developed from lemon juice and by 1833, carbonated lemonade was on sale in England. Soon, other flavours were introduced and in 1886, Coca Cola entered the market and created soft drink history.

Food from scratch…

• Noodles

A 4000 year old bowl of noodles unearthed in China is the earliest example ever found of one of the world’s most popular foods. Noodles have been a staple food in many parts of the world for at least 2000 years. But who inverted the noodle? This is a hotly contested topic – with the Chinese , Italian and Arabs all staking a claim.

•Ice cream

The first ice cream was probably made by chance when someone left some milk outside on a cold night and it froze!

Alexander the great enjoyed ice cream made with milk, fruit juice, honey and snow in the 4th century B.C. and the Roman emperor Nero ordered ice to ne brought from the mountains and combined it with fruit toppings. The Chinese also had a method of making ice creams and some believe that ice cream came to Europe from China.

It was Quintus Maximus, a roman general, who first wrote down a recipe for ice cream. Marco Polo brought the Chinese recipe to Venice after his visit to Peking. The king of England, Charles I is supposed to have offered his chef a handsome reward to keep his ice cream recipe a secret!

You favourite ice cream cone was invented by a pastry maker Ernest Hamwi in 1904, at the World Fair in St. Louis. He put a scoop of ice cream on his pastry when an ice cream seller in a neighbouring stall ran out of dishes- and it became an instant hit!

• Chocolate

Cocoa, from which chocolate is made is said to have originated in the Amazon atleast 4000 years ago. The origins of chocolate can be traced back to the ancient Mayan and Aztec civilization in central America, who first enjoyed ‘chocolatel’, a much prized spicy drink made from roasted cocoa beans, the Aztecs believed that the cocoa tree was a gift from their God, Quetzalcoatl. According to legend, He had been banished by the other gods for giving the tree to mankind, but he promised to return to them one day.

The Spanish, led by Hernando Cortez, invaded Mexico in the 16th century. When the Aztecs saw Cortez, they believed their god had returned and welcomed him with a golden cup of chocolate! When Cortez returned to Spain in 1528, he loaded his galleons with cocoa beans and equipment for making the chocolate drink. Soon ‘chocolate’ became a fashionable drink enjoyed by the rich in Spain.

It was in 1847 that solid chocolate, as we know of today, was made by Fry and sons of Bristol by mixing sugar with cocoa powder and cocoa butter and your favourite treat was born.

• Chewing gum

Thousands of years ago people chewed gum in it’s natural form. The most common ancient chewing gum was tree resin lumps, but people chewed various sweet grasses, leaves, grains and waxes also. The first commercial Chewing gum was made and sold in 1848 by John Bacon Curtis. He made a sticky, rubbery material from the spruce tree which could be chewed. In the 1860’s, Thomas Adams began selling chicle, a gum from the sapodilla tree of Mexico’s Yucatan desert.

Story of the two most expensive spices

• Saffron

One pound of saffron costs you $5000. It is the most expensive spice next comes vanilla. Saffron is a complicated spice to harvest. Harvesting saffron needs a lot of hand work to pick up the flowers, separate the saffron that is the dried stigma or the female part of the flower. Saffron comes from the saffron crocus flower and each flower has 3 stigmas. The yield of saffron is very low. One pound of saffron requires 170000 flowers. These flowers bloom over a six week period from late September to early December. There is a specific time to day to harvest them. High relative humidity and sunlight can break the chemical structure in the saffron. Early morning is preferably the best time to harvest them.

90% of the world’s saffron is grown in arid fields in Iran. It is so because workers are available and for cheap. But it’s mostly like slavery. Most workers are women getting five dollars a day. Not only Iran, it’s grown in Morocco, Spain, Italy, the Netherlands, Afghanistan, India and even in United States. Though many Americans have never eaten saffron, the US imports large amount of saffron. Saffron has a resistance to cold weather.

Over centuries saffron has proven useful in many situations. Most commonly used in cooking. Middle east Asian countries have a lot of food containing saffron. When saffron is broken down it creates a golden dye. Which is how when used in cooking it gives a different kind of colour and taste and smell to it.

Saffron contains some chemical components which are really expensive like picrocrocin, crocin and safranal. These are the main components responsible for the taste, smell and colour.

People have tried passing turmeric, red marigold petals, and lily flower stigma as saffron. But the flavour and dye is totally different. In large quantities, saffron can be a potent happiness inducing narcotic. Research suggests it may help reduce the symptoms for Alzheimer’s, depression and PMS.

• Vanilla

From ice cream to cakes and even perfume, vanilla is the go-to flavour of the world. In recent years, the price of natural vanilla has shot up. At one point it was more expensive than silver by weight. 80% of the world’s vanilla is grown in the perfectly suited climate of the north east region of Madagascar. It’s the country’s primary export crop. In 2014, vanilla was $80 a kilo. Three years later it was $600. Today its around $500. The price rise is due in part to global demand. The trend of eating naturally means that food companies have shunned synthetic flavouring in favour of the real deal.

Price fluctuations affect producers of agricultural commodities everywhere but vanilla is particularly volatile. In just a few weeks the price can jump or plummet by over 20%. Liberalisation is one reason for such movements. The Malagasy government once regulated the vanilla industry and it’s price. But now the price is negotiated at the point of sale which makes for a freer market but a more volatile one. It’s also a tiny industry. A single cyclone can knock up the entire crop within Madagascar. It’s also a difficult and delicate crop to grow.

Vanilla is an orchid that needs to be hand pollinated. This is a really labour intensive practice. It takes roughly six months to grow it on the vine and then six months of manual post harvesting. The interesting thing about vanilla is that it needs to be taken off the vine when it is almost rotted!

The growers have to contend with another problem. Thieves are targeting vanilla crops. So Malagasy now have to sleep out in their vanilla fields. They can’t rely on those who are changed from the state to protect them or their crops. Some farmers have resorted to harvesting the beans before they’re ripe but this produces a poorer quality vanilla and ultimately pushes down the price. The combination of deteriorating quality and high prices is having an effect. The vanilla price bubble may burst. If the price continues to stay high there’s a number of scenarios that will play out. Continuation of current situation will cause an unstable market. Otherwise the corporate sectors step in, try to regulate the market in some way that may stabilise prices and also quality. Or the market may crash out.

Big buyers that provide vanilla are now working directly with farmers in a bid to gain greater control over quality. Other companies have started to look elsewhere for their natural vanilla. Indonesia, Uganda and even the Netherlands are growing the crop. For a century Madagascar has enjoyed a near monopoly on vanilla. But this industry maybe in line for radical overhaul.

Bermuda triangle and other mysteries

•Bermuda triangle

The Bermuda triangle is a region of the Atlantic Ocean between Bermuda and Florida, where ships and planes have mysteriously disappeared. Vincent Gaddis, who wrote about the disappearance named the region: ‘the deadly Bermuda triangle’.

The legend of the Bermuda triangle was uncovered when E.V.W. Jones, a reporter penned an article on a strange occurrence he had stumbled across. It seemed that an unusual number of planes and ships had been disappearing in the ocean between Florida and Bermuda. Over the years more than 200 separate mysterious disappearances have been attributed to the Bermuda triangle. No trace was ever found of the crafts or their passengers. The disappearance of Flight 19, ranks at the very top of Bermuda triangle lore. In 1945, five Navy planes vanished while on a routine training mission over the Atlantic. The media really went over board putting forward theories as to what might have happened at Bermuda triangle. The theories range from attacks by sea monsters to freak killer waves and kidnappings by aliens. However, later studies reveal that most of the incidents have been inaccurately reported and many agencies have declared the number and nature of disappearances in the region is similar to any other area of the sea.

•Islands that vanished mysteriously

Have you heard of the Aurora islands? Even if you have, you are unlikely to ever see them, for they have vanished from the face of the Earth! The story begins in the 18th century when the captain if the ship sailing in the South Atlantic waters saw three small islands called the Aurora Islands after the name of the first ship. They soon became a common landmarks for the Spanish ships that routinely went to south America and then suddenly, the islands disappeared!

Since most islands are produced through volcanic activity, they can appear and disappear just as quickly over time and leave no trace for sea explorers to find. This maybe the explanation why another phantom island, Isla Grande, which lay just to the North of Aurora islands, has now vanished too. However, this explanation does not hold good for the disappearance of islands called Davis’ Land. There is even an island named the Isle of Brasil, which keeps appearing off and on near the coast of Ireland.

• Uniqueness of Stonehenge

On the misty green plains of Salisbury, in southern England, stands one of the most mystical of the megaliths- Stonehenge. The beauty of these stones take one’s breath away. The 3.96 meters high stones are unique in that unlike the other megaliths, each stone has been artificially shaped into a curve. As a result, when they were assembled, they formed the outer line of a circle, when seen from above. At the same time, each stone has a slight bulge, so that when seen from below, they appeared to be in a straight line! Amazing isn’t it?

The astonishing scale and beauty of the stones, the great care and labour in construction and the mystery that surrounds their original purpose are just some of the reasons why Stonehenge is one of the most popular sights in England. Stonehenge is a magical experience indeed.

Should commercial surrogacy be banned in India?

Commercial surrogacy is the process by which an individual or couple pays a fee to a woman in exchange for her carrying and delivering a baby. At birth the child, homo-sexual couples, and single people who wish to be parents are the most common types of people who seek surrogate mothers.

Commercial surrogacy has been legal in India from 2002 onwards but due to unethical practices, a bill has been approved by the Union Cabinet in August 2016. This one lapsed when Parliament adjourned without taking the measure for a vote.

The new proposal came in 2019 that is to ban commercial surrogacy. The Indian minister of health has called the 2019 bill a “need of the hour” citing a rough estimate that between 2000 to 3000 unregulated clinics currently operate in the country. Under the new law anyone who performs or promotes this would be punished with up to 10 year of imprisonment and a fine up to one million rupees. The surrogacy bill’s provision restricting surrogacy to married heterosexual couples within strict age ranges also discriminates against members of L G B T community, older couples and unmarried people who might seek to have a child. The bill goes against the principles of equality provided under Article 14 of the Indian constitution.

Regulation, not ban, is needed. The commercial surrogacy in India needs a regulation and stricter rules that could ensure good care and pay to the woman alone and not agents or others. Good clinical facilities for the surrogate mother and a healthy environment where she could stay safely before and after delivery could lessen exploitation. There is no provision in the law about the custody of the child if the couple later refuse to accept it if the child is mentally challenged or born with a defect. People who hire surrogates have a need to do so due to medical reasons. It is not their choice. Regulation on this practice is very much needed and must be done to close loopholes due to which exploitation of surrogate mothers is taking place.

Indian society is yet to progress so much as to accept surrogate motherhood. The woman who rents her womb even if for the cause of humanity towards an unfortunate couple will never be accepted in society when she goes back to her normal life. People will look down on her and she may probably not be able to find a husband, if she was unmarried at the time of surrogacy. We need to be broad-minded and accept these women and respect their choice of renting their wombs.

Giving women a safe and free environment for surrogacy can help in curbing the evils attached and the industry could do well along with giving good money to such poor women so that they can make their lives better as well as give prosperity to their families.

Are Gandhian principles relevant today?

Gandhiji was a national leader of India who forced the Britishers to leave India without resorting to violence. He is regarded both as a transformational leader and a leader of the masses. Every year on 2nd October, we celebrate Mahatma Gandhi’s birth anniversary and recall his principles and philosophies. It is a fact that Gandhiji adhered to his principles of non violence, truth and satyagraha with utmost sincerity to achieve his goals. Many people argue that all his principles hold good in today’s world. We all have moved years ahead with lots of changes in lives, innovations in science and technology, vivid variety of lifestyles. Here the point is if the principles and ideologies of Gandhi are still relevant or practical in modern world or not.

YES

•Gandhiji’s principle are valid and everlasting His principles are based on truth and non-violence are the base of civilized human society. He practically proved to the whole world that a war can be fought without indulging in violence. In modern world violence is increasing rapidly. Nuclear weapons and terrorism are becoming common these days. More and more People are resorting to violence and divided into religious and ethnic compartments. We need guidance and the direction to save the world from this desperate situation.

• Gandhiji is an inspiration to international leaders also.

Gandhian principles are followed not only by national leaders but also by some eminent foreign leaders like Dalai Lama, Barack Obama, Martin Luther King Jr, Nelson Mandela etc.

• Gandhi’s principles of economic independence valid even today

Even today, our Prime minister has launched a programme ‘Make in India’ which very much reflects Gandhiji’s principles of spinning Khadi and giving employment to thousands of poor people.

NO

• Violence multiplies on being non-violent

In today’s era, violence can best be answered by violence. Those who remain silent when treated with violence suffer even worse if they do not fire back in the same way.

• Modern culture outplays Gandhian swawlambi philosophy

In today’s modern world, trends and fashion have taken a new shape and so people wear trendy outfits and by no means they are restricted to use self made khadi clothes as part of ‘Swawlambi’ philosophy of Gandhiji.

• Principle of truth not valid today

In a world where money is the most important part of life, big business houses and capitalists thrive on lies to make huge profits. Advertising agencies most of the time try to cheat people by projecting false claims. Today values and meaning of the success are far more different from the values of Gandhiji.

To conclude we can say that some of Gandhian principles are relevant even today, though some of them have become outdated and irrelevant. The principle of non violence cannot be ignored. Gandhiji’s vision cannot be ignored as they form the very base on which a new generation of decision makers must adapt in order to compete on the global level. If the energy of the youth can receive honest and selfless motivation and direction from the experienced then India can surely progress. Gandhi’s vision should not be lost in religious, political and emotional fervours. It must be reorganized and reconstructed for a brighter and logical future.

Should writers and artists have an unrestricted right to expression?

Freedom of expression means the right to express one’s own conviction and opinions freely by word of mouth, by writing, through painting or any other mode. In modern times it is widely accepted that the right to freedom of expression is necessary in a democratic society and this right must be safeguarded at all times. Liberty to express opinions and ideas without hindrance and especially without fear of punishment plays a significant role in the development of society. It is one of the most important fundamental liberties guaranteed against state suppression or regulation. However, this freedom needs to be tempered so that it does not hurt the sentiments of others.

• ‘Freedom of expression’ originally guaranteed by the Indian constitution Prior to 1972, Article 19 (1) of the Indian constitution guaranteed this freedom of expression. However, after 1972, Indian politicians felt this should be restricted as they feared that they will be ridiculed or otherwise harmed politically if it remained unrestricted. So, they enacted laws to limit the freedom of expression on various grounds under the garb of law and order, national security and other noble objectives.

• Restriction to freedom of speech causes suffering Many writers, speakers, cartoonists etc. belonging to different castes, creeds and social positions have suffered and are suffering due to the restrictions imposed by law. On most occasions they have been charged and arrested, causing them mental anguish and physical/financial suffering.

• Freedom of expression should be protected Important justifications for freedom of expression and speech are that they assist in the discovery of truth, help an individual to attain self fulfilment etc. ultimately results in the welfare of society and state and strengthen the capacity of an individual in participating in decision making in a democracy.

However, no freedom is absolute and unrestricted. It is necessary to exercise freedoms in order to have a democratic society, but their limitations are also needed for the maintenance of the democratic society. So, the freedom has to have suitable restrictions.
