BENGALI THE LANGUAGE

Bengali languageBengali Bangla, member of the Indo-Aryan group of the Indo-Iranian branch of the Indo-European language family. It is spoken by more than 210 million people as a first or second language, with some 100 million Bengali speakers in Bangladesh; about 85 million in India, primarily in the states of West BengalAssam, and Tripura; and sizable immigrant communities in the United Kingdom, the United States, and the Middle East. It is the state language of Bangladesh and one of the languages officially recognized in the constitution of India.

History

There is general agreement that in the distant past OriyaAssamese, and Bengali formed a single branch, from which Oriya split off first and Assamese later. This is one reason that the earliest specimens of Bengali language and literature, the Charyapadas (Buddhist mystic songs), are also claimed by speakers of Oriya and Assamese as their own.
The Bengali linguists Suniti Kumar Chatterji and Sukumar Sen suggested that Bengali had its origin in the 10th century CE, deriving from Magahi Prakrit (a spoken language) through Magahi Apabhramsha(its written counterpart). The Bengali scholar Muhammad Shahidullah and his followers offered a competing theory, suggesting that the language began in the 7th century CE and developed from spoken and written Gauda (also, respectively, a Prakrit and an Apabhramsha).
Although Bengali is an Indo-European language, it has been influenced by other language families prevalent in South Asia, notably the Dravidian, the Austroasiatic, and the Tibeto-Burman families, all of which contributed to Bengali vocabulary and provided the language with some structural forms. In the 1960s and ’70s, Chatterji examined dictionaries from the early 20th century and attributed slightly more than half of the Bengali vocabulary to native words (i.e., naturally modified Sanskrit words, corrupted forms of Sanskrit words, and loanwords from non-Indo-European languages), about 45 percent to unmodified Sanskrit words, and the remainder to foreign words. Dominant in the last group was Persian, which was also the source of some grammatical forms. More recent studies suggest that the use of native and foreign words has been increasing, mainly because of the preference of Bengali speakers for the colloquial style.

Varieties

There are two standard styles in Bengali: the Sadhubhasa (elegant or genteel speech) and the Chaltibhasa (current or colloquial speech). The former was largely shaped by the language of early Bengali poetical works. In the 19th century it became standardized as the literary language and also as the appropriate vehicle for business and personal exchanges. Although it was at times used for oration, Sadhubhasa was not the language of daily communication.
Chaltibhasa is based on the cultivated form of the dialects of Kolkata(Calcutta) and its neighbouring small towns on the Bhagirathi River. It has come into literary use since the early 20th century, and by the early 21st century it had become the dominant literary language as well as the standard colloquial form of speech among the educated. The pronouns and verb forms of the Sadhubhasa are contracted in Chaltibhasa. There is also a marked difference in vocabulary.
Although distinctions in the use of Bengali are associated with social class, educational level, and religion, the greatest differences are regional. The four main dialects roughly approximate the ancient political divisions of the Bengali-speaking world, known as Radha (West Bengal proper); Pundra, or Varendra (the northern parts of West Bengal and Bangladesh); Kamrupa (northeastern Bangladesh); and Bangla (the dialects of the rest of Bangladesh; see also Bangladesh: history). In addition, two cities, Sylhet and Chittagong, have developed dialects with lexical and phonological characteristics that are mostly unintelligible to other speakers of Bengali.

Grammar

A simple Bengali sentence usually follows subject–object–verb word order. When present, the negative particle comes at the end of the sentence. The copula, or verb linking the subject and predicate, is often omitted. Six cases are generally recognized. Compound verbs, comprising a stem or root and a suffix, are a special feature. There are 3 verb tenses, but their subdivisions make them 10. There are two moods, indicative and imperative, and two numbers, singular and plural. The first, second, and third persons are expressed through six forms because they have both ordinary and honorific referents. Gender is natural, and there is no special declension for feminine and neuter. Adjectives are usually not modified according to the number or case of the nouns they qualify.

Writing Systems

The Bengali script is derived from Brahmi, one of the two ancient Indian scripts, and particularly from the eastern variety of Brahmi. Bengali script followed a different line of development from that of Devanagariand Oriyan scripts, but the characters of Bengali and Assamese scripts generally coincided. By the 12th century CE the Bengali alphabet was nearly complete, although natural changes continued to take place until the 16th century. Some conscious alterations were also made in the 19th century.
Bengali is written from left to right. There are no capital letters. The script is characterized by many conjuncts, upstrokes, downstrokes, and other features that hang from a horizontal line. The punctuation marks, save one, are all taken from 19th-century English.
Bengali spelling was more or less standardized through a set of reforms that were initiated by the University of Calcutta in 1936. However, the standardization process continued throughout the 20th and into the early 21st century. For instance, the Bangla Academy in Dhaka prefers a set of alternatives offered by the 1936 reforms, while the Bangla Academy in West Bengal has proposed new reforms. Visva-Bharati, the university founded by the Bengali poet and Nobelist Rabindranath Tagore, has also effected several spelling variations. Finally, some newspapers and publishers have their own house styles. Not surprisingly, these independent efforts to standardize Bengali orthography have helped to create a degree of confusion.

A team led by Kolkata-born scientists has found that a special sweet spot in the eye called 'fovea' plays a crucial role in humans being able to to focus on computer screens and also read, an ability which is unique to Homo sapiens.
The findings decipher the mechanism that lets humans reading this text, recognising faces, enjoying colours, say the scientists.
Raunak Sinha and Mrinalini Hoon describe themselves as a 'scientist couple' who push the frontiers of neuroscience to better understand vision.


Ready for dinner 16 feet underwater?

If you're bored of your regular dining options and are looking for something new and exciting, consider trying out a new restaurant called 'The Pearl' in Brussels. 
However, to eat here, you have to put on scuba gear and flippers.
Why? Because, this place is located underwater at the bottom of a swimming pool, five metres (16 feet) below the surface.
Once you make it to the restaurant, you and your dinner companion will remove your equipment and climb inside a two-metre wide pod.
The underwater capsule has a little table inside where you'll sit and enjoy your food. Just like at regular restaurants, the food is brought to you by waiters who are expert scuba divers.
The waiters deliver foie gras, lobster salad and champagne in waterproof cases before leaving the diners peering out of the portholes, enjoying the strange tranquility of eating in an air pocket, completely submerged.
It’s also fairly exclusive, with room for just four people. 
The Pearl is described as looking like a golf ball with windows. It is also supplied with oxygen by NEMO33, which is important for breathing.
After reading all this you may tempted to experience this unusual restaurant. Right?
So pack your bags and travel to Brussels, Belgium where ‘The Pearl’ is located. Also pay around $106 per person to get a reservation and enjoy the food underwater.

Gurugram Traffic Is So Bad That Kidnappers Let Go Of An Abducted Man

You may never have thought that the killer traffic jam at Gurugram may turn out to be a blessing in disguise for someone. In a fortunate (and amusing) turn of events, miscreants who tried to abduct the toll plaza official at Kherki Daula, Gurugram, let go of him after getting stuck in a traffic jam.
The incident took place at around 10:15 am, when a man driving a Mercedes car refused to pay the toll tax of Rs 60.
The accused also presented a fake driving licence, following which the accused and Manoj Kumar, the toll booth’s assistant manager ended up in a heated argument.
Toll Plaza
An hour later, the same Mercedes returned with three more men and another 15 men riding a Toyota Fortuner. They then abducted Manoj Kumar at gun point. 
The gang, however, refrained from opening fire as they were inching closer to the toll booth. They chose to drive off some 150 metres away from the booth and thrash Kumar black and blue.
Here's the CCTV footage:

As the traffic at the toll plaza kept increasing, the abductors had no other choice but to let go off the manager. Speaking to HT, Manoj Kumar said, ‘They feared being seen or caught trying to take me away.’
The Kherki Daula police have registred a case for assault and abduction under IPC section.
Just a few days ago, a Congress leader refused to pay the toll fee and assaulted an operator at the same booth, however, no action has been taken so far. 

Dear New York Times Do You Still Think ISRO Should Be Kept Outside The 'Elite Club'

For the past couple of years, every time the ISRO registers a success, The New York Times has been on the receiving end of being trolled by Indians.
This is because in October 2014 the NYT did an utterly tasteless job of mocking India's Mangalyaan success with a cartoon.
It depicted an Indian, with a cow knocking on the doors of the 'Elite Space Club'.
The New York Times

As expected, the cartoon which came at a time when ISRO's space mission was at its peak didn't go down well with Indians.
They trolled the NYT for days until they issued an apology.
But the cartoon has not gone away from the memory. And it has once again come back to haunt them.

So dear NYT, here is some reply!

TOI

Now, how does that feel?

Here Are The Men Who Made ISRO’s World Record 104 Satellite Launch Possible

ISRO is one of the smallest space agencies in the world in terms of budgets. A mere $1.1 billion compared to NASA’s nearly $19 billion. And when you consider the achievements, it really makes you wonder how ISRO does it. Well, we’ll tell you, it’s the men and women of ISRO who make it possible.

Dr K Sivan, Director VSCC

The Vikram Sarabhai Space Centre in Trivandrum is where design and development activities for all the launch vehicles take place. The centre conducts research on everything, from design of rockets to fuels and composite materials and guidance systems.
The PSLV rocket that put all the 104 satellites in orbit was designed here. The centre is headed by Dr K Sivan who has been with ISRO since 1982. He designed software called SITARA, which ISRO uses for simulating trajectories of rockets.
He also led the RLV-TD project and was involved in its design qualification, aerodynamic characterisation and hardware development. The PSLV-C37 launch carried innovative experiments such as using the IRNSS navigation system for predicting the orbit of the satellites.

An expert in launch vehicle design, S Somnath joined ISRO back in 1985. He got associated with PSLV program early on during its design stages and led the team during the first two developmental flights of the PSLV. Later, as the Project Manager of the vehicle engineering and launch services management of PSLV Project, he was responsible for the mechanisms and pyro-technique systems of the launch vehicle. Under him, the Liquid Propulsion Systems Centre built the liquid rocket stages for the PSLV rocket and the bigger GSLV. He was also responsible for the successful sub-orbital test flight of the GSLV Mk3 LVM3-X mission.

Having joined ISRO in 1986, Kunhikrishnan was responsible for the flight certification of all the avionics systems of launch vehicles like the PSLV and GSLV. Under his leadership since 2010, the PSLV project completed more than 13 successful flights without any glitches.
These missions include the Mars Orbiter Mission, a launch of PSLV-C19 that carried the heaviest Indian remote sensing satellite launched by PSLV. Now as the Director at Satish Dhawan Space Centre (SDSC) SHAR, Sriharikota all the launches taking place come under his command.
Yesterday’s launch of PSLV-C37 was the shortest for a PSLV mission which translates to quicker launches.

The Space Applications Center is where all the systems that go into the Indian satellites are made. The centre is led by Tapan Misra, who has been with ISRO since 1984. Back in 1990 as a guest scientist at German Space Agency, he wrote an algorithm for the real-time processing of Synthetic Aperture Radar data. He also invented the algorithm called track steering algorithm for high-resolution processing of SAR data for Disaster Management.
Under his leadership, the centre built the Cartosat 2D satellite and for the first time used a 3D printed mirror supporting structure to hold the lens of the multispectral camera. Innovation by his team led to the lens taking up less space within the satellite. He also led the development of an indigenous solid state data recorder. He has two patents to his name, 6 pending patents, 5 copyrights and 25 papers to his name.

Dr M Annadurai, Director ISAC

The ISRO Satellite Centre is where all the satellite sub-systems come together to form the final product. The Cartosat 2D, the biggest payload on the PSLV-C37 was completed by ISAC. Dr Annadurai had been asked by the Chairman of ISRO to build the satellite by January 26, but Annadurai’s team did it well before time. Usually, a repeat satellite (previous Cartosat launch was in June) usually takes a year. He and his team are also preparing the GSAT series of satellites that will be launched in the coming months from Sirharikota.
