Truth behind sinking of Titanic

On 10 April 1912, when the largest ocean liner in service at that time, RMS Titanic, started its maiden voyage from Southampton, it was a new beginning in the history. With at least 2,224 people on board, including a number of prominent personalities, the luxury ship that nicknamed as ‘Millionaire’s Special’ was en route to New York City on that day.

Designed to be the epitome of style and safety, the vessel featured many advanced luxury and safety features. Moreover, the ‘unsinkable’ RMS Titanic was commanded by a senior captain, 62-year-old Captain Edward Smith, again ensuring the safety of the vessel and its passengers.

However, the destiny of this spectacular ship was already made. On the 14th of April, the world witnessed what could easily be considered as its most deadly civilian maritime disaster – the sinking of the great Ship Titanic. On that fateful night, at ­­around 11.40 PM Titanic struck an iceberg off the coast of Newfoundland and began to sink.

Over the course of the next few hours, people witnessed the biggest catastrophe to hit the world, and at 2.20 AM on the morning of the 15th, the biggest ship that the world had seen settled to the bottom of the North Atlantic.

The sea, the sinking of the ship and the cold weather were enough to take the lives of 1517 passengers and crew on board. Just 706 of them survived the ordeal to tell the horrific and sad tale to the world.

Why the ‘unsinkable’ Titanic sunk?

As the news of the Titanic disaster reached land, there was shock and outrage directed against several issues that possibly led to the accident. Many legends and conspiracy theories arose almost immediately after the accident on those who died and survived, and also on the reasons behind the sinking of the vessel.

How did the Titanic sink in spite of having the best technical design available at the time seemed a mystery for a long time? This was the question that baffled many scientists and engineers for days after the disaster.

Immediately after the sinking, the investigations into the matter began and in fact, two separate inquiries had been set up – one by the United States Senate and the other by the British Board of Trade.

The U.S inquiry was headed by Senator William Alden Smith and the British one by Lord Mersey. The surviving passengers and the very crew who managed to escape from the clutches of death gave their versions of the tragedy and the investigations were concluded quickly, though the initial questioning and detail gathering took more than a few months.

The results of the investigations revealed that many of the safety measures and regulations of the international maritime were outdated and required a second look. The ship itself was found short on a few of the standards

Subhash Chandra Bose-an unsung hero

Subhash Chandra Bose was a great Indian nationalist. People even today know him by love for his country. This true Indian man was born on the 23rd of January in 1897. Most noteworthy, he fought with bravery against the British rule. Subhash Chandra Bose was certainly a revolutionary freedom fighter.

Contribution of Subhash Chandra Bose in the Indian Independence

The participation of Subhash Chandra Bose took place with the Civil Disobedience Movement. This is how Subhash Chandra Bose became part of the Indian Independence movement. He became a member of the Indian National Congress (INC). Also, in 1939 he became the party president. However, this was for a short time only because of his resignation from this post.

The British put Subhash Chandra Bose under house arrest. This was because of his opposition to British rule. However, due to his cleverness, he secretly left the country in 1941. He then went to Europe to seek help against the British. Most noteworthy, he sought the help of Russians and Germans against the British.

Subhash Chandra Bose went to Japan in 1943. This was because the Japanese gave their agreement to his appeal for help. In Japan Subhash Chandra Bose began the formation of the Indian National Army. Most noteworthy, he did the formation of a provisional government. The axis powers during the Second World War certainly recognized this provisional government.

The Indian National Army attacked the North-eastern parts of India. Furthermore, this attack took place under the leadership of Subhash Chandra Bose. Also, the INA was successful in capturing a few portions. Unfortunately, there was the surrender of INA due to weather and Japanese policies. However, Bose made his Refusal to surrender clear. He escaped on a plane but this plane most probably crashed. Due to this, Subhash Chandra Bose died on 18 August 1945.

Ideology of Subhash Chandra Bose

First of all, Subhash Chandra Bose strongly supported the complete independence of India. In contrast, the Congress Committee initially wanted independence in phases, through Dominion status. Furthermore, Bose was elected president of Congress for two consecutive terms. But due to his ideological conflicts with Gandhi and Congress, Bose took resignation. Bose was against Mahatma Gandhi’s approach of non-violence. Subhash Chandra Bose was a supporter of violent resistance.

Subhash Chandra Bose saw 2nd World War as a great opportunity. He saw this as an opportunity to take advantage of British weakness. Also, he went to USSR, Germany, and Japan to seek help. He led the INA to the fight against the British.
Subhash Chandra Bose was a strong believer in Bhagwat Gita. It was his belief that Bhagwat Gita was a great source of inspiration for the fight against the British. He also held Swami Vivekananda’s teachings in high-esteem.

In conclusion, Subhash Chandra Bose is an unforgettable national hero. He had tremendous love for his country. Furthermore, this great personality sacrificed his whole life for the country.

Jagannath Rath yatra

Jagannath Rath yatra is one of the oldest rath yatra taking place in india.It is also known as The Charoit Festival.Every year on shukla paksha Dwatiya of Ashada month ,the festival commemorates Lord Jagannath’s annual visit to Gundicha temple,Puri.

This year the yatra held on, July 12 with all the covid -19 protocol.

Transportation in India.

India’s transport sector is large and diverse; it caters to the needs of 1.1 billion people. In 2007, the sector contributed about 5.5 percent to the nation’s GDP, with road transportation contributing the lion’s share.

Good physical connectivity in the urban and rural areas is essential for economic growth. Since the early 1990s, India’s growing economy has witnessed a rise in demand for transport infrastructure and services.

However, the sector has not been able to keep pace with rising demand and is proving to be a drag on the economy. Major improvements in the sector are therefore required to support the country’s continued economic growth and to reduce poverty.

Roads. Roads are the dominant mode of transportation in India today. They carry almost 85 percent of the country’s passenger traffic and more than 60 percent of its freight. The density of India’s highway network — at 0.66 km of roads per square kilometer of land – is similar to that of the United States (0.65) and much greater than China’s (0.16) or Brazil’s (0.20). However, most roads in India are narrow and congested with poor surface quality, and 33 percent of India’s villages do not have access to all-weather roads.

Rural Roads-A Lifeline for Villages in India: Connecting Hinterland to Social Services and markets

Railways. Indian Railways is one of the largest railways under the single management. It carried some 19.8 million passengers and 2.4 million tonnes of freight a day in year 2009 and is one of the world’s largest employer. The railways play a leading role in carrying passengers and cargo across India’s vast territory. However, most of its major corridors have capacity constraint requiring capacity enhancement plans.

Ports. India has 13 major and 199 minor and intermediate ports along its more than 7500 km long coastline. India’s seaborne foreign trade being 95% by volume and 67% by value, the ports play a very significant role in improving foreign trade in a growing economy. These ports serve the country’s growing foreign trade in petroleum products, iron ore, and coal, as well as the increasing movement of containers. Indian ports handled cargo of 850 million tonnes and about 9.0 million TEU container traffic in year 2010. Over the last decade, the average annual growth rate of port cargo volume has been about 10%.. The future potential for port sector, particularly container ports is huge considering that the container traffic is projected to grow to 40 million TEU by 2025. Inland water transportation also remains largely undeveloped despite India’s 14,000 kilometers of navigable rivers and canals.

Aviation. India has 128 airports, including 15 international airports. Indian airports handled 142 million passengers in 2010-11 and 1.6 million tonnes of cargo in year 2009-10. The CAGR for the domestic passenger and freight growth over the last decade has been 14.2% and 7.8% respectively. The dramatic increase in air traffic for both passengers and cargo in recent years has placed a heavy strain on the country’s major airports. Passenger traffic is projected to grow more than 15% annually over 2011-13 and it is estimated that the aviation industry, currently 9th largest in the World, will require 30 billion USD investment in the next 15 years to keep pace with the growing demand.

Urban Transport. India is experiencing rapid urbanization with the present urbanization levels at 30% translating to a population of roughly 340 million living in urban areas. The number of million plus cities is presently at 42 and the urban economy accountd for roughly 60% of the GDP. Motorisation rates in India are in double digits as in most developing economies. Only about 20 cities out of 87 cities with a population in excess of 500,000 and state capitals have any kind of organized transport and only 3-4 cities could lay claim to a mass rapid transit system. The share of public transport in cities with population sizes over 4 million has declined from 69% to 38% between 1994 to 2007. Accident and fatality rates are one of the highest in the world affecting primarily the poor and vulnerable without their own means of transport.

Transport infrastructure in India is better developed in the southern and southwestern parts of the country.

The major challenges facing the sector are:

• India’s roads are congested and of poor quality. Lane capacity is low – majority of national highways are two lanes or less. A quarter of all India’s highways are congested. Many roads are of poor quality and road maintenance remains under-funded. This leads to the deterioration of roads and high transport costs for users.

• Rural areas have poor access. Roads are significant for the development of the rural areas – home to almost 70 percent of India’s population. Although the rural road network is extensive, some 33 percent of India’s villages do not have access to all-weather roads and remain cut off during the monsoon season. The problem is more acute in India’s northern and northeastern states which are poorly linked to the country’s major economic centers.

• The railways are facing severe capacity constraints. All the country’s high-density rail corridors face severe capacity constraints. Also, freight transportation costs by rail are much higher than in most countries as freight tariffs in India have been kept high to subsidize passenger traffic.

• Urban centers are severely congested. In Mumbai, Delhi and other metropolitan centers, roads are often severely congested during the rush hours. The dramatic growth in vehicle ownership during the past decade – has reduced rush hour speeds especially in the central areas of major cities.

• Ports are congested and inefficient. The average annual growth of cargo volume in the ports in the last decade was close to 10%, However, capacity utilization in some of the major ports remain as low as 58-60% Both bulk and containerized traffic is expected to grow at a much faster pace in future and by some estimate the container traffic is projected to grow to about 4.5 times of the current volume by 2025. India’s ports need to significantly ramp up their capacity and efficiency to meet this surging demand.

• Airport infrastructure is strained. . Air traffic has been growing rapidly leading to severe strain on infrastructure at major airports, especially in the Delhi and Mumbai airports which account for more than 40 percent of nation’s air traffic.

Kang Yatze

Kang Yatze or Kang Yatse (elevation 6,496 metres (21,312 ft)) is a mountain located at the end of the Markha Valley in the Himalayas in Ladakh. It is located in the Hemis National Park, not long away from the capital Leh.

The mountain has two summits. The true eastern summit is higher at 6,400 m but requires an extremely technical traverse across a knife-edge ridge for the mountaineers wishing to conquer it. The lower western peak (Kang Yatze II) is easier and more frequently climbed, although it is lower at about 6270m.

Kang Yatze II

The lower peak is mainly done from mid-June till September end. There are two approach routes to this peak. One is from Chilling and trekking through the Markha Valley, passing the villages of Skyu, Markha and Hankar. There is another approach that starts from the village of Shang-Sumdo and steeply climbs up the Markha Gorge passing by the campsite of Chyuskirmo, Lartsa and then climbing the Gongmaru La(Pass), a 5130 meter high pass to reach Nimaling. This peak is easier compared to the main lower western peak and does not require any technical mountaineering skills. From the very top, distant peaks of East Karakoram ranges are visible on a clear day.

Kang Yatze I

Kang Yatze I or the Eastern summit requires an intermediate Camp to be set up. The climb to Camp 1 is a short one but over a steep scree and cliffs zone. There is an alternative route following the Glacier where Camp 1 can be set as well. From Camp 1, the climb gets technical. The last 500 meters of the peak is very steep and mandatory fixed ropes.

LIBRARIES: A BOON TO THE SOCIETY

THE HARD COPY OF LIBRARY

According to WIKIPEDIA, “A library is a collection of materials, books or media that are easily accessible for use and not just for display purposes. It is responsible for housing updated information in order to meet the user’s needs on a daily basis. A Library provides physical (hard copies documents) or digital access (soft copies) materials, and may be a physical location or a virtual space, or both. A library’s collection can include printed materials and other physical resources in many formats such as DVDs, CDs and Cassette as well as access to information, music or other content held on bibliographic databases.”

IMPORTANCE OF LIBRARIES TO MAN

Libraries are said to be the storehouse of culture. If a man is to be known by the company he keeps, society is to be known by the number of good libraries it has. Man’s craving for knowledge is eternal. He wants to know more; he wants to enjoy more. But he cannot always move about for various reasons. He goes to a library and reads books of his choice. Libraries preserve books of various types, old and new. There are also periodicals and daily papers to meet the demands of the people. In all ages, libraries have been considered to be the best medium of public instructions.

The doors of library are exposed to everyone for rewarding the requirement for information. They are run by the government, schools, colleges, and universities. The society members of the neighbouring locality can visit these libraries to boost their information and complete their research.

TYPES OF LIBRARIES

There are different types of libraries, such as public libraries, circulating libraries, private or personal libraries. Of these, public libraries are most important. These are financed either by Government or by public institutions. All readers are allowed to read here. These libraries have two sections-lending and reference. Books are lent out to those who deposit money. Others are allowed to sit a id read books during the period, these are kept open. As libraries spread education, the Government of India have taken up a scheme to establish rural libraries for the benefit of rural people. They sanction annual grants to these libraries in cash or kind. In these libraries, books are stocked to suit the half-literate people of villages.

A FRIEND IN NEED

Government-managed libraries are well equipped and well manned. Only technical men are employed here to help the readers. Quite a large number of scholars, students and members of the public daily attend such libraries for reading and making notes. There are public libraries organised by public institutions. These libraries cater to the needs of a large number of people living in particular localities. Students of schools and colleges also utilise these libraries and derive benefit from them. But these libraries are in bad shape. Government grants to these libraries are not adequate. Public-spirited men now-a-days, are rare. Development of libraries is an important task of a welfare Government. Common people and students get opportunities to read in these libraries. In our country where the percentage of illiteracy is high, these libraries help in expanding the facilities for reading. Public libraries and rural libraries do a lot of good to the localities where they are established. Now the Government has established primary unit libraries, town libraries etc. The Government gives regular grants for the purchase of books and equipment. But still the grants are not adequate. However, they help the public libraries to satisfy the needs and aspirations of the local people.

CONCLUSIONS

So, if we can see deeply a library Builds and helps to connect Community, it Provide Access to the full range of information resources needed to live, learn, govern, and work. It Promote Literacy to both children and adults. It Protect Your Rights to read and offers freedom of information gathering and sharing. People becomes innovative and smart in the company of library, which enhances creation and collaboration.

Derinkuyu-The Underground city

We know the term “city “that is on the ground,but there is another term when associated with the term city gives of a thrilling vibes and piques the curiosity of people and the term is “UNDERGROUND”

“Underground city” it is a city which is literally as the name says underneath the ground.
So today we are going to discuss about a city called “Derinkuyu”.

From viator.com

It is an ancient multi-level underground city in Turkey.

It is the deepest excavated underground city in Cappadocia and a stunning wonder.

The city is said extends to a depth of 200 feet and could have sheltered as many as 20,000 people together.

Derinkuyu city is famous for its capacity to hold thousands of families that is one of the highest among many underground cities that were found.

It’s said that this city dwelling not only could hold thousands of people, but also contained everything an entire population would need to survive any crises.

There are numerous subterranean dwellings and secret tunnel passages that were used as shelters.

From:Getyourguide

The underground city at Derinkuyu could be closed from the inside with large stone doors enhancing the security measures up a notch and each floor could be closed off separately.



It had aminities such as wine and oil presses, stables, cellars, storage rooms, refectories, and chapels.

On the second floor is a spacious room with a barrel-vaulted ceilings ,and rooms were used as a religious school and for study purposes.


There is a series of vertical staircases between the 3rd and 4 th floor leading to the church located at lowest level.

From:Shutterstock


There is a large 55-metre ventilation shaft a which seemed to provide water to both the villagers above and, if the outside world was not accessible, to those in hiding.

What fascinates me is how did they build this city without having any access to the technology and designed it beautifully and they took all kinds off possibilities into account making a city which is anytime ready to face any kind of problem.

It is said to be one of the top most tourist destinations in Turkey. You can also visit this by booking tickets in a trusted website.

Thankyou^^.

Bridal Mysticism Across Religions

Photo by Arina Krasnikova on Pexels.com

Mysticism is a word derived from the Greek word ‘Mysticos’ which refers to the belief that a person has the potential to achieve oneness with the god. Spirituality and mystics have been around for a long time. It’s a part of humanity that defines a diviner affinity to the belief that God is watching over us and our ultimate goal in this life is to achieve oneness with God. Over the years, there have been several religions that have emerged all over the world, but one of the key differences that separates a spiritual mystic from the others is the fact that they have the tendency to break away from tradition and hence, other forms of religious practices which were considered the norm.

I watch the clouds rupture.
Mira says, nothing can harm him.
This passion has yet
to be slaked.
-Mirabai (Clouds)

A mystic might take on any sort of relationship with the God and it is not restricted to the traditional hierarchical relationship where God is the supreme force who rules over the devotees. The devotees might choose friendship, teacher-student bond, familial bonding or even romantic companionship with their God. Thus, the concept of Bridal mysticism isn’t a new one. It has been around for several ages and is a true form of devotion where a devotee loves their god as they would love their beloved.

Let him kiss me with the kisses of his mouth! For your love is more delightful than wine.
-Song of Solomon (1:2)

The mode of bridal mysticism is so unique, for it negates all the humane all the societal constraints that denies sexuality to women. Bridal Mysticism has no such earthly constraints, it celebrates and even glorifies the bodily union between a devotee and their god, for sexual union is considered to be one of the divinest methods of indicating oneness with God. In this relationship, it is not just the devotee who expresses love, they also understand that their God loves them similarly, just as passionately.  The love that persists between the devotee and the heavenly one is pure and true.

If I adore You out of fear of Hell, burn me in Hell!
If I adore you out of desire for Paradise,
Lock me out of Paradise.
But if I adore you for Yourself alone,
Do not deny to me Your eternal beauty.”
-Rabia Al Basri

Bridal mysticism is a practice that can be seen all over the world across all religions. In Christianity, the most explicit, yet the purest form of Bridal mysticism can be found in ‘Songs of Solomon’; a collection of love poems that has been included in the first testament. In it, two lovers go through a series of events that includes periods of blissful union as well as separation. It has been interpreted in several ways over the years, but the love that is cherished between the lover and her beloved is pure. In Hinduism, we see clear indications of Bridal mysticism in the poems of Mirabai from northern India and Antal from southern India. Both of the women adored and loved the Hindu God Lord Krishna. Like any couples, they express their love, grief, jealousy and fiery passion to their beloved God and relish in the devotion that flows through them. In Islam, the Sufi mystics are known for their poetic works which are brimmed with their love for God. Sufi saints like Rabia spoke of a divine selfless love for God which criticised those who loved God out of fear.

Bridal mysticism is also not gender specific. There are numerous instances of devotees from all genders expressing a romantic love, despite the conventional norms. Bridal Mysticism is thus one of the purest forms of devotion that solidifies the bond between a God and their devotee.

HISTORY OF ” THE KHOISAN TRIBE”

Khoisan people represent ‘earliest branch off human family tree. The Khoisan people of southern Africa have been recognised as one of the earliest formed distinct human genetic groups.Some 22,000 years ago, they were the largest group of humans on earth,the Khoisan, a tribe of hunter-gatherers in southern Africa. Today, only about 100,000 Khoisan, who are also known as Bushmen, remain.

The Khoisan people from Southern Africa maintained ancient lifestyles as hunter-gatherers or pastoralists up to modern times, though little else is known about their early history. Here we infer early demographic histories of modern humans using whole-genome sequences of five Khoisan individuals and one Bantu speaker. Coalescent analysis shows that the Khoisan and their ancestors have been the largest populations since their split with the non-Khoisan population ~100–150 k yr ago. In contrast, the ancestors of the non-Khoisan groups, including Bantu-speakers and non-Africans, experienced population declines after the split and lost more than half of their genetic diversity. Paleoclimate records indicate that the precipitation in southern Africa increased ~80–100 k yr ago while west-central Africa became drier.

ORIGIN OF KHOISAN TRIBE :

In around 2300 BP (Before Present), hunter-gatherers called the San acquired domestic stock in what is now modern day Botswana. Their population grew, and spread throughout the Western half of South Africa. They were the first pastoralists in southern Africa, and called themselves Khoikhoi (or Khoe), which means ‘men of men’ or ‘the real people’. This name was chosen to show pride in their past and culture. The Khoikhoi brought a new way of life to South Africa and to the San, who were hunter-gatherers as opposed to herders. This led to misunderstandings and subsequent conflict between the two groups.

The Khoikhoi were the first native people to come into contact with the Dutch settlers in the mid 17th century. As the Dutch took over land for farms, the Khoikhoi were dispossessed, exterminated, or enslaved and therefore their numbers dwindled. The Khoikhoi were called the ‘Hottentots’ by European settlers because the sound of their language was so different from any European language, and they could not pronounce many of the words and sounds.

The Khoikhoi used a word while dancing that sounded like ‘Hottentots’ and therefore settlers referred to the Khoikhoi by this name – however today this term is considered derogatory. The settlers used the term ‘Bushmen’ for the San, a term also considered derogatory today. Many of those whom the colonists called ‘Bushmen’ were in fact Khoikhoi or former Khoikhoi. For this reason, scholars sometimes find it convenient to refer to hunters and herders together as ‘Khoisan’.

When European settlement began, Khoikhoi groups called the Namaqua were settled in modern day Namibia and the north-eastern Cape; others, including the Korana, along the Orange River; and the Gonaqua, interspersed among the Xhosa in the Eastern Cape. But the largest concentration of Khoikhoi,numbering in the tens of thousands inhabited the well-watered pasture lands of the south-western Cape. These ‘Cape’ Khoikhoi would be the first African population to bear the brunt of White settlement.

NOMADIC HERITAGE :

The Khoikhoi kept herds of animals such as goat, cattle and sheep and had to move around to find enough grazing land for their animals. They moved according to the seasons and only stayed in one place for a few weeks. This meant that they had to be able to carry all their belongings themselves, or load them onto the backs of their animals.

Houses had to be very light and easy to erect and take apart. For this reason they were made of thin poles covered with reed mats. Even pots and buckets were made of wood with small handles to make them easier to tie to animals’ backs. They also wore clothes made of leather, like the San.

The animals, especially cattle, were a sign of wealth and the Khoikhoi only ate cattle that had died or had been stolen from their enemies. They only killed their own animals for important occasions like funerals or weddings. The women milked the animals and gathered wild plants from the veld and the men killed game for everyday food. This shows that the Khoikhoi hunted and gathered, but also herded animals.

Hottentot (racial term) - Wikipedia

KHOIKHOI SOCIETY AND LANGUAGE :

Khoikhoi society consisted of both rich and poor, as animals – which were a sign of wealth – could belong to individuals. This is because animals provided food, clothes and transport. This was completely different from the San, who were all considered equal and shared everything. Wealthier Khoikhoi people would share their milk with poorer members of their group, but would still be considered more important. They would also rub animal fat over their bodies to show their wealth.

THE KORA :

The Korana or Kora were a nomadic Khoikhoi group that probably derived their name from a chief called Kora (or Gora), who was originally a leader of the Gorachouqua (`-qua’ meaning ‘people of’). This leader detached himself from this group with his followers and became the first great chief of the Korana.

Initially there were two main groups, the Great Korana and the Little Korana. Each of these broke into splinter groups that divided until there were many groups whose names have been slowly forgotten or were not recorded. Quarrels over water and grazing rights, or the ownership of women or livestock usually caused the divisions amongst groups. When parties split up they usually assumed the name of their leader. But sometimes they took the name of a place where they had stayed for a long time.

One such case was the name Hoogekraal (`High Kraal’), the original name for Pacaltsdorp, near George. Korana family names tended to signify a special characteristic or occupation such as the Towenaars (Sorcerers) and the Regshande (Right-handers). Where the first Chief Kora lived is unknown, but in early times, most Korana lived near the Gariep, Vaal and Harts rivers and others moved into the Overberg and the Karoo.

The last great Korana trek took place during the late 17th century, when they trekked from their chiefdoms in the south-western Cape to escape pressure from White settlers. These Korana trekkers travelled along the western trading routes as far north as the great river that they called Gariep, which means ‘river’. The early pioneers added ‘Groot’ (Great) to it, and after that, it was simply known as the Groot Rivier. A Dutch soldier of Scottish extraction, Robert Jacob Gordon, who was commander of the garrison at the Cape in 1777, renamed it the Orange after the Prince of Orange. However, many still referred to it as the Groot Rivier. After the 1994 change of government, it was given back its original name, Gariep.

For many centuries the early people lived along this river and its tributaries because game was able to graze in the vleie and the berry trees and bulbous plants grew in profusion. There, the Korana settled among the Nama herders and groups of San hunter-gatherers. By then, the Korana had become well-armed and some sources cite that they lived very much in the style of the ‘Wild West’. They knew how to ride horses, understood the value of keeping their mounts in prime condition, and frequently raided the farms south of the great river and the Baster communities.

They also settled in what is today the Free State, the district that became known as Koranaland (Gordonia). Many small conflicts over hunting and plundering took place between these groups and the Bantu-speaking peoples and White trekkers in the area. It is important to note however, that livestock raids were carried out by a minority group of Korana.

GROUPS IN TO RAIDERS :

The small conflicts over cattle and land raids came to a head in 1868, when the colonial government created a special magisterial district. The Northern Border Protection Act was passed to permit action against the Korana. A special border unit was stationed at Kenhardt, but the handful of police and burghers were too few to protect a 330 km stretch of land. This eventually led to the Korana wars of 1869 and 1878.

In 1869, the Frontier Armed and Mounted Police and a small detachment of the Royal Artillery arrived in the area – led by Sir Walter Currie. Later, a prolonged drought forced White settlers and Coloured farmers, as well as the Korana, to move closer to the Gariep River. Such a conglomeration of herds close made it easy for Korana ‘raider’ groups to prey on the herds, and their activities aroused the ire of the district.

Klaas Lukas, who was initially neutral, gathered together 1,000-armed men to defend their livestock. His supporters included the majority of the Korana. The Korana ‘raider’ groups were defeated and came under the control of the Cape Government. Those Korana who rejected a future under colonial rule trekked further into the Kalahari. The Cape Government settled the Basters near Upington to form a buffer between the Boers and the Korana. Today, the Korana have almost completely disappeared as a separate group through assimilation with the population in the area.‘Bastaards’ or ‘Baster’ was a derogatory referred to offspring of liaisons between Europeans, slaves and Khoikhoi. The term was also used to refer to subordinate Blacks who could speak Dutch, ride and shoot.

THE KORANA WERE THE “SOCIAL GLUE ” OF THE GHAAP:

There were often close and complex relationships between the Bushmen and the Korana. When the Korana made war on the Bushmen, they captured Bushman women and children – who were then integrated into the Korana community as wives. Bushmen would sometimes assist Korana in raiding parties, or as messengers and herdsmen. Korana groups traded dagga and tobacco for honey and the Bushmen’s honey and honey beer. Some Bushmen would pay reciprocal visits to Korana kraals.

The Bushmen are hunters and food-gatherers, the Hottentots are also herders. The latter work iron, which the Bushmen have never learned to do. The Bushmen, on the other hand, have a graphic art that stands out as one of the achievements of man- kind, while the Hottentots have no art at all.

​Some of the Korana clans also had close relationships with the Tswana. The Koranas called the Thlaping the “Briquas”, and exchanged products from them, such as tobacco and sibilo.  Of great importance is that several key Tswana chiefs took Kora wives. When the Tlhaping came to the Langberg in the 1770s, they, and some southern communities, developed close relationships with the Kora who were settled along the Orange. Maswe, the Tlhaping chief at this time, took a Kora wife.

The Untold story of Begum Hazrat Mahal

Begum Hazrat Mahal’s name was Muhammedi khanum, born in Faziabad, Awadh, India. She was sold by her parents, and became a courtesan by profession. 

She entered the royal harem as a khawasin after having been sold to Royal agents, where she was promoted to a pari, and was known as Mahak Pari. She became a Begum after being accepted as a royal concubine of the King of Awadh, the last Tajdaar-e-Awadh, Wajid Ali Shah; became his junior wife and the title ‘Hazrat Mahal’ was bestowed on her after the birth of their son, Birjis Qadr. 

In 1856, the British annexed Awadh, and Wajid Ali Shah was exiled to Calcutta. She was eventually to take charge of the affairs of the state of Awadh despite her divorce from the Nawab. 

Begum Hazrat Mahal (1820 – 7 April 1879), also known as the Begum of Awadh, was the second wife of Nawab of Awadh Wajid Ali Shah, and the regent of Awadh in 1857-1858. She is known for the leading role she had in the rebellion against the British East India Company during the Indian Rebellion of 1857. 

After her husband had been exiled to Calcutta and the Indian Rebellion broke out, she made her son, Prince Birjis Qadr, the Wali (ruler) of Awadh, with herself as regent during his minority. However, she was forced to abandon this role after a short reign. She finally found asylum in Nepal onto Hallaur, she died in 1879 Nepal. Her role in the rebellion has given her a heroine status. 

Indian Rebellion of 1857 

During the Indian Rebellion of 1857, Begum Hazrat Mahal’s band of supporters rebelled against the forces of the British under the leadership of Raja Jalal Singh; they seized control of Lucknow, and she took power as the guardian of her minor son, Prince Birjis Qadr, whom she had declared as the ruler (Wali) of Awadh.[3] As regent, she automatically came to have a leadership role in the rebellion against the British. 

One of the principal complaints of Begum Hazrat Mahal was that the East India Company had casually demolished Temples and mosques just to make way for roads. In a proclamation issued during the final days of the revolt, she mocked the British claim to allow freedom of worship: 

To eat pigs and drink wine, to bite greased cartridges and to mix pig’s fat with sweetmeats, to destroy Hindu and Mussalman temples on the pretense of making roads, to build churches, to send clergymen into the streets to preach the Christian religion, to institute English schools, and pay people a monthly stipend for learning the English sciences, while the places of worship of Hindus and Mussalmans are to this day entirely neglected; with all this, how can people believe that religion will not be interfered with? 

Hazrat Mahal worked in association with Nana Saheb, but later joined the Maulavi of Faizabad in the attack on Shahjahanpur. 

When the forces under the command of the British re-captured Lucknow and most of Oudh, she was forced to retreat. 

Later life 

Ultimately, she had to retreat to Nepal, where she was initially refused asylum by the Rana prime minister Jang Bahadur, but was later allowed to stay. 

She died there in 1879 and was buried in a nameless grave in the grounds of Kathmandu’s Jama Masjid. 

After her death, on the occasion of the jubilee of Queen Victoria (1887), the British Government pardoned Birjis Qadr and he was allowed to return home.

|Ageing Dams|

India is ranked third in the world in terms of building large dams, of the over 5,200 large dams built so far, about 1,100 large dams have already reached 50 years of age and some are older than 120 years.

Minor and medium dam shelf-life is lower than large dams for example Krishna Raja Sagar dam built in 1931 is 90 years old and Mettur dam built in 1934 is 87 years old.

Implications of ageing dams:

In a paper ‘supply-side hydrology last gasp’ Rohan D’Souza writes the siltation rate of Bhakra dam is 130.86 % so at this rate it will function for merely 47 years as against the original estimate of 88 years.

When when the dams ages the soil replaces water, the supply of water decreases and this in turn leads to reduction in the cropped area as  less water is received and which increases dependency on on the rain which is erratic in nature and groundwater is overexploited, the crop yield increases and farmers income thereby decreases.

By 2050 this will pose difficulties such as scarcity of water to feed the ever increasing population.

The flawed siltation rates reinforce the argument that designed flood cushions within several reservoirs across many river basins may have already depleted substantially due to which floods become more frequent downstream of dams. For example the flooding of Bharuch in 2020, Kerala in 2018 and Chennai 2015 a few examples attributed to downstream releases from reservoirs.

Way forward:

The way forward in the situation can be the building of medium or minor irrigation based small storage structures, identifying mechanisms to recharge aquifers and store water underground.

Hence, India will eventually feel difficulty in finding sufficient water in the 21st century to feed the rising population by 2050, grow abundant crops, create sustainable cities, or ensure growth. Therefore all stakeholders must come together to address this situation urgently.

What is Astrophysics?

Hubble Snaps 'Monkey Head' Nebula
Astrophysics is a branch of space science that applies the laws of physics and chemistry to explain the birth, life and death of stars, planets, galaxies, nebulae and other objects in the universe. It has two sibling sciences, astronomy and cosmology, and the lines between them blur. 

In the most rigid sense:
Astronomy measures positions, luminosities, motions and other characteristics
Astrophysics creates physical theories of small to medium-size structures in the universe
Cosmology does this for the largest structures, and the universe as a whole. 

In practice, the three professions form a tight-knit family. Ask for the position of a nebula or what kind of light it emits, and the astronomer might answer first. Ask what the nebula is made of and how it formed and the astrophysicist will pipe up. Ask how the data fit with the formation of the universe, and the cosmologist would probably jump in. But watch out — for any of these questions, two or three may start talking at once!
Goals of astrophysics
Astrophysicists seek to understand the universe and our place in it. At NASA, the goals of astrophysics are “to discover how the universe works, explore how it began and evolved, and search for life on planets around other stars,” according NASA’s website.

NASA states that those goals produce three broad questions:

  • How does the universe work?
  • How did we get here?
  • Are we alone?

It began with Newton

While astronomy is one of the oldest sciences, theoretical astrophysics began with Isaac Newton. Prior to Newton, astronomers described the motions of heavenly bodies using complex mathematical models without a physical basis. Newton showed that a single theory simultaneously explains the orbits of moons and planets in space and the trajectory of a cannonball on Earth. This added to the body of evidence for the (then) startling conclusion that the heavens and Earth are subject to the same physical laws.

Perhaps what most completely separated Newton’s model from previous ones is that it is predictive as well as descriptive. Based on aberrations in the orbit of Uranus, astronomers predicted the position of a new planet, which was then observed and named Neptune. Being predictive as well as descriptive is the sign of a mature science, and astrophysics is in this category.

Milestones in astrophysics

Because the only way we interact with distant objects is by observing the radiation they emit, much of astrophysics has to do with deducing theories that explain the mechanisms that produce this radiation, and provide ideas for how to extract the most information from it. The first ideas about the nature of stars emerged in the mid-19th century from the blossoming science of spectral analysis, which means observing the specific frequencies of light that particular substances absorb and emit when heated. Spectral analysis remains essential to the triumvirate of space sciences, both guiding and testing new theories.

Early spectroscopy provided the first evidence that stars contain substances also present on Earth. Spectroscopy revealed that some nebulae are purely gaseous, while some contain stars. This later helped cement the idea that some nebulae were not nebulae at all — they were other galaxies! 

In the early 1920s, Cecilia Payne discovered, using spectroscopy, that stars are predominantly hydrogen (at least until their old age). The spectra of stars also allowed astrophysicists to determine the speed at which they move toward or away from Earth. Just like the sound a vehicle emits is different moving toward us or away from us, because of the Doppler shift, the spectra of stars will change in the same way. In the 1930s, by combining the Doppler shift and Einstein’s theory of general relativity, Edwin Hubble provided solid evidence that the universe is expanding. This is also predicted by Einstein’s theory, and together form the basis of the Big Bang Theory.

Also in the mid-19th century, the physicists Lord Kelvin (William Thomson) and Gustav Von Helmholtz speculated that gravitational collapse could power the sun, but eventually realized that energy produced this way would only last 100,000 years. Fifty years later, Einstein’s famous E=mc2 equation gave astrophysicists the first clue to what the true source of energy might be (although it turns out that gravitational collapse does play an important role). As nuclear physics, quantum mechanics and particle physics grew in the first half of the 20th century, it became possible to formulate theories for how nuclear fusion could power stars. These theories describe how stars form, live and die, and successfully explain the observed distribution of types of stars, their spectra, luminosities, ages and other features.

Astrophysics is the physics of stars and other distant bodies in the universe, but it also hits close to home. According to the Big Bang Theory, the first stars were almost entirely hydrogen. The nuclear fusion process that energizes them smashes together hydrogen atoms to form the heavier element helium. In 1957, the husband-and-wife astronomer team of Geoffrey and Margaret Burbidge, along with physicists William Alfred Fowler and Fred Hoyle, showed how, as stars age, they produce heavier and heavier elements, which they pass on to later generations of stars in ever-greater quantities. It is only in the final stages of the lives of more recent stars that the elements making up the Earth, such as iron (32.1 percent), oxygen (30.1 percent), silicon (15.1 percent), are produced. Another of these elements is carbon, which together with oxygen, make up the bulk of the mass of all living things, including us. Thus, astrophysics tells us that, while we are not all stars, we are all stardust.

Astrophysics as a career

Advertisement

Becoming an astrophysicist requires years of observation, training and work. But you can start becoming involved in a small way even in elementary and high school, by joining astronomy clubs, attending local astronomy events, taking free online courses in astronomy and astrophysics, and keeping up with news in the field on a website such as Space.com. 

In college, students should aim to (eventually) complete a doctorate in astrophysics, and then take on a post-doctoral position in astrophysics. Astrophysicists can work for the government, university labs and, occasionally, private organizations.

Study.com further recommends the following steps to put you on the path to being an astrophysicist:

Take math and science classes all through high school. Make sure to take a wide variety of science classes. Astronomy and astrophysics often blend elements of biology, chemistry and other sciences to better understand phenomena in the universe. Also keep an eye out for any summer jobs or internships in math or science. Even volunteer work can help bolster your resume.

Pursue a math- or science-related bachelor’s degree. While a bachelor in astrophysics is the ideal, there are many other paths to that field. You can do undergraduate study in computer science, for example, which is important to help you analyze data. It’s best to speak to your high school guidance counselor or local university to find out what degree programs will help you.

Take on research opportunities. Many universities have labs in which students participate in discoveries — and sometimes even get published. Agencies such as NASA also offer internships from time to time. 

Finish a doctorate in astrophysics. A Ph.D. is a long haul, but the U.S. Bureau of Labor Statistics points out that most astrophysicists do have a doctoral degree. Make sure to include courses in astronomy, computer science, mathematics, physics and statistics to have a wide base of knowledge.

Natalie Hinkel, a planetary astrophysicist who was then at Arizona State University, gave a lengthy interview with Lifehacker in 2015 that provided a glimpse into the rewards and challenges of being a junior astrophysics researcher. She described the long number of years she has put into doing her research, the frequent job switches, her work hours and what it’s like to be a woman in a competitive field. She also had an interesting insight about what she actually did day to day. Very little of her time is spent at the telescope.

“I spend the vast majority of my time programming. Most people assume that astronomers spend all of their time at telescopes, but that’s only a very small fraction of the job, if at all. I do some observations, but in the past few years I’ve only been observing twice for a total of about two weeks,” Hinkel told Lifehacker. 

“Once you get the data, you have to reduce it (i.e. take out the bad parts and process it for real information), usually combine it with other data in order to see the whole picture, and then write a paper about your findings. Since each observation run typically yields data from multiple stars, you don’t need to spend all of your time at the telescope to have enough work.”

Energy-harvesting design aims to turn high-frequency electromagnetic waves into usable power

Device for harnessing terahertz radiation might help power some portable electronics.

Terahertz waves are pervasive in our daily lives, and if harnessed, their concentrated power could potentially serve as an alternate energy source. Imagine, for instance, a cellphone add-on that passively soaks up ambient T-rays and uses their energy to charge your phone.

Terahertz waves are electromagnetic radiation with a frequency somewhere between microwaves and infrared light. Also known as “T-rays,” they are produced by almost anything that registers a temperature, including our own bodies and the inanimate objects around us.

Terahertz waves are pervasive in our daily lives, and if harnessed, their concentrated power could potentially serve as an alternate energy source. However, to date there has been no practical way to capture and convert them into any usable form.

Now physicists at MIT have come up with a blueprint for a device they believe would be able to convert terahertz waves into a direct current, a form of electricity that powers many household electronics.

Their design takes advantage of the quantum mechanical, or atomic behavior of the carbon material graphene. They found that by combining graphene with another material, in this case, boron nitride, the electrons in graphene should skew their motion toward a common direction. Any incoming terahertz waves should “shuttle” graphene’s electrons, like so many tiny air traffic controllers, to flow through the material in a single direction, as a direct current.

The researchers have published their results today in the journal Science Advances, and are working with experimentalists to turn their design into a physical device.

“We are surrounded by electromagnetic waves,” says lead author Hiroki Isobe, a postdoc in MIT’s Materials Research Laboratory. “If we can convert that energy into an energy source we can use for daily life, that would help to address the energy challenges we are facing right now.”

Isobe’s co-authors are Liang Fu, the Lawrence C. and Sarah W. Biedenharn Career Development Associate Professor of Physics at MIT; and Su-yang Xu, a former MIT postdoc who is now an assistant professor chemistry at Harvard University.

Breaking graphene’s symmetry

Over the last decade, scientists have looked for ways to harvest and convert ambient energy into usable electrical energy. They have done so mainly through rectifiers, devices that are designed to convert electromagnetic waves from their oscillating (alternating) current to direct current.

Most rectifiers are designed to convert low-frequency waves such as radio waves, using an electrical circuit with diodes to generate an electric field that can steer radio waves through the device as a DC current. These rectifiers only work up to a certain frequency, and have not been able to accommodate the terahertz range.

A few experimental technologies that have been able to convert terahertz waves into DC current do so only at ultracold temperatures — setups that would be difficult to implement in practical applications.

Instead of turning electromagnetic waves into a DC current by applying an external electric field in a device, Isobe wondered whether, at a quantum mechanical level, a material’s own electrons could be induced to flow in one direction, in order to steer incoming terahertz waves into a DC current.

Such a material would have to be very clean, or free of impurities, in order for the electrons in the material to flow through without scattering off irregularities in the material. Graphene, he found, was the ideal starting material.

To direct graphene’s electrons to flow in one direction, he would have to break the material’s inherent symmetry, or what physicists call “inversion.” Normally, graphene’s electrons feel an equal force between them, meaning that any incoming energy would scatter the electrons in all directions, symmetrically. Isobe looked for ways to break graphene’s inversion and induce an asymmetric flow of electrons in response to incoming energy.

Looking through the literature, he found that others had experimented with graphene by placing it atop a layer of boron nitride, a similar honeycomb lattice made of two types of atoms — boron and nitrogen. They found that in this arrangement, the forces between graphene’s electrons were knocked out of balance: Electrons closer to boron felt a certain force while electrons closer to nitrogen experienced a different pull. The overall effect was what physicists call “skew scattering,” in which clouds of electrons skew their motion in one direction.

Isobe developed a systematic theoretical study of all the ways electrons in graphene might scatter in combination with an underlying substrate such as boron nitride, and how this electron scattering would affect any incoming electromagnetic waves, particularly in the terahertz frequency range.

He found that electrons were driven by incoming terahertz waves to skew in one direction, and this skew motion generates a DC current, if graphene were relatively pure. If too many impurities did exist in graphene, they would act as obstacles in the path of electron clouds, causing these clouds to scatter in all directions, rather than moving as one.

“With many impurities, this skewed motion just ends up oscillating, and any incoming terahertz energy is lost through this oscillation,” Isobe explains. “So we want a clean sample to effectively get a skewed motion.”

One direction

They also found that the stronger the incoming terahertz energy, the more of that energy a device can convert to DC current. This means that any device that converts T-rays should also include a way to concentrate those waves before they enter the device.

With all this in mind, the researchers drew up a blueprint for a terahertz rectifier that consists of a small square of graphene that sits atop a layer of boron nitride and is sandwiched within an antenna that would collect and concentrate ambient terahertz radiation, boosting its signal enough to convert it into a DC current.

“This would work very much like a solar cell, except for a different frequency range, to passively collect and convert ambient energy,” Fu says.

The team has filed a patent for the new “high-frequency rectification” design, and the researchers are working with experimental physicists at MIT to develop a physical device based on their design, which should be able to work at room temperature, versus the ultracold temperatures required for previous terahertz rectifiers and detectors.

“If a device works at room temperature, we can use it for many portable applications,” Isobe says.

He envisions that, in the near future, terahertz rectifiers may be used, for instance, to wirelessly power implants in a patient’s body, without requiring surgery to change an implant’s batteries.

“We are taking a quantum material with some asymmetry at the atomic scale, that can now  be utilized, which opens up a lot of possibilities,” Fu says.

This research was funded in part by the U.S. Army Research Laboratory and the U.S. Army Research Office through the Institute for Soldier Nanotechnologies (ISN).
