The House that Chisholm built

Chisholm01CF06mar2019

We often read and hear of the history of Chennai’s Senate House — but what of its present and future?

I am delighted to see that some use has at last been made of the University of Madras’ Senate House as was promised, when this magnificent “Work of Genius” was restored in 2008 to celebrate the 150th Anniversary of the founding of that premier educational institution.

Parts of the Chennai Photo Biennale exhibition were mounted here recently and had visitors once again admiring the interior of this bit of architectural splendour.

The story of this building goes back to July 1864. It was suggested at the time that the first office buildings of the University, then located in Presidency College, be established in a building called Senate House to be raised on Marshall’s Road. However, Governor Lord Napier, in his Minute dated November 28, 1867, stated his views categorically. He wrote:

“The site on Marshall’s Road stands at a great distance from the Presidency College, the College of Civil Engineers, the Medical College, the principal schools and the quarters which supply the greatest number of students and persons concerned in literary pursuits. But it is hoped that the University buildings will not be circumscribed to a mere hall or Senate House for the offering of Degrees and other rare solemnities. We expect that, eventually, University Professorships will be established and that University lectures will be delivered (emphasis mine). Even at the present moment it is most desirable that a University library should be founded, which would serve as the General Public library for the studious classes in the capital, a library in which the valuable Manuscripts belonging to the Government may be lodged and in which the past and current publications of the Presidency (which we are now directed to register and preserve) may be deposited and, as I trust, united with an ample collection of works useful to the general student and particularly interesting to the educated inhabitants of Southern India. If such should be the eventual character of the University buildings, it is obvious that nothing is more desirable than to place them in some degree of juxtaposition with the principal haunts of education and to provide them with cheerful attractive aspects as well as a good supply of air… (emphasis mine).

Chisholm02CF06mar2019

“The proposals which I accordingly submit to Council are comprised under the following heads:-

(i) To affirm that the proper site for a University building is the ground between the Marine Villa and the Revenue Board office” (off the beach).

Work then began 150 years ago, in 1869, at a site where the Nawab’s Artillery Park fired gun salutes to greet visiting dignitaries, and in the style of The Nawab’s Octagon, Nawab Wallajah’s bathing pavilion. The University offices moved into Senate House in 1879.

The design of the building was by Robert Fellowes Chisholm. The designs of Chisholm, a young engineer who had joined the Bengal PWD in 1859, were chosen the winners of two competitions in 1864. A 21-year-old Chisholm arrived in Madras in 1865 to supervise the building of both sites. In 1872, he was appointed Consulting Architect to the Government of Madras, an appointment pushed through by Governor Lord Napier who virtually became his patron. In 1877, he was also appointed the Superintendent of the Government School of Industrial Arts (now the College of Arts and Crafts). He retired in 1889 to take up similar positions with the Gaekwad of Baroda. He left India in 1902 to practice in London. Apart from his work in Madras he was responsible for designing some of the finest 19th Century buildings in India. Amongst them are the Lakshmi Vilas Palace and the Museum in Baroda, the Napier Museum, Trivandrum, the Lawrence (Asylum) School and Town Library in Ootacamund, and the Rangoon Cathedral. He was also responsible for the restoration of the Tirumala Nayak’s Palace in Madurai. During his twenty years in Madras, he not only changed the city skyline, but he spread the Indo-Sarcenic architectural style he was considered master of throughout India. Senate House was planned to integrate with Chepauk Palace, to which he made several additions and amendments.

Chisholm03CF06mar2019

In 2006 a committee was formed at the University to celebrate in 2008 the 150th anniversary of the Institution. This committee, together with the Indian National Trust for Art and Cultural Heritage, Chennai chapter, as well as several corporates raised around ₹7,00,00,000 to restore Senate House and ready it for the sesquicentenary celebrations. Restoration completed, promise was made that the building would, as in the past, be put to good public use.

This never really happened and Senate House became virtually a godown. Fortunately the Chennai Photo Biennale has lit a candle that may yet prove the lamp to lead the way to regular public use of this magnificent building.

The forgotten plaque

It was a fairly prominent story the other day and its headline read “Facelift for Saidapet Bridge”. A fresh coat of paint and new grills at a cost of ₹43 lakh were promised. Not a word about heritage significance here.

The Saidapet Bridge is officially called the Maraimalai Adigal Bridge and connects Saidapet with Guindy. But from ancient times it has been called the Marmalong Bridge, though those with a sense of history remember it as Coja Petrus Uscan’s Bridge, recalling that that legendary Armenian, “John Company’s most loyal friend”, developed a causeway here into a bridge linking Saidapet with St. Thomas’ Mount. He also endowed its maintenance as well as that of the steps to the Mount.

Chisholm04CF06mar2019

A stone plaque at the northern end of the bridge remembers the munificence of the Armenian who left a fortune for the public good, particularly the Roman Catholic Church. For years, heritage enthusiasts have campaigned to save this historic memorial stone and it is only good fortune that has still kept it in sight despite all the Metro work around it. What is surprising is that in the most recent news story no mention has been made of the Uscan memorial and saving this listed heritage monument for posterity.

My picture today shows the plaque in position during the last week of February 2019. Surely a facelift to Saidapet Bridge must include giving prominence to this plaque and narrating the story of the city’s benefactor who died in 1757.

I hope that during the facelift for the Marmalong / Saidapet / Maraimalai Adigal / Petrus Uscan Bridge, more attention will be paid to the plaque than there is in the news story or in real life.

IIT-Madras and Sankara Nethralaya bring out path-breaking treatment for retinoblastoma

According to the statement, the research will help in ensuring better treatment for retinoblastoma that affects one in every 1,500 children across the world.

Chennai :

The IIT-M and Sankara Nethralaya researchers have identified pathways by which diseased cells in retinoblastoma, a form of eye cancer, obtains energy for growth and survival, said a statement issued by the institute.

According to the statement, the research will help in ensuring better treatment for retinoblastoma that affects one in every 1,500 children across the world.

The research study has led to the identification of five more new drug targets that can be used for treating the eye cancer. The research will offer the potential for developing new and more effective drugs with minimal side-effects.

The published work is the first study to use Constraint-Based Modeling (CBM) to predict metabolic biomarkers for diagnosis of Retinoblastoma in Indian patients and to suggest novel drug targets for its treatment.Their work has recently been published in the Journal of Federation of European Biochemical Societies letters. Leading medical and genomics research organizations in India and the US have contributed to this research.

In India alone,1,500 new cases of Paediatric Retinoblastoma are reported daily, adding tremendously to the socio-economic burden of cancer care. Most common symptoms of this disease are appearance of a white dot in the retina and squint. As with most forms of cancer, the key to retinoblastoma management is early detection and treatment.

Chennai’s Senate House opens its doors to the public

Senate01CF27feb2019

The beauty of its Moorish-themed walls and exquisite high ceiling is no longer hidden behind shuttered windows — Senate House is one of the venues of Chennai Photo Biennale

It stands at the site of what was once the Nawab of Arcot’s artillery park. From its shady boulevard guns were fired to greet visitors. Today, Senate House stands a silent sentinel gazing at the Marina as students mill about its grounds, pigeons roost in its eaves and visitors throng the Chennai Photo Biennale’s exhibition held in its ornate halls.

Shuchi Kapoor, founding member, CPB, who was also instrumental in getting permission for venues, says, “We had heard about how beautiful Senate Hall was and how it would lend itself to the Biennale. We started work on getting permissions to host exhibitions in 2017 and through The Hindu, Goethe Institut and the Head of the Department of Journalism were able to access the office of the Vice Chancellor. It took us a year to get the permission. It had been renovated recently but hadn’t been used. Despite low maintenance it was impressive when opened up and we knew it would make for a perfect venue. We hope this will push our ‘adopt a venue’ programme, going forward, that will involve corporates lending support to upkeep these lovely spaces.”

Senate02CF27feb2019

Senate House was completed in 1879. The library and teaching departments were built in similar style to lend it continuity. The fragile beauty of Senate House was the result of the genius of Robert Fellowes Chisholm who as a young engineer at 21 won a contest and was chosen to design Presidency College and a building to house the offices of the University. Chisholm is also credited with designing the Lakshmi Vilas Palace and the Museum in Baroda, Lawrence school in Ooty and the Rangoon Cathedral. In a way, he changed the skyline of Madras and by the end of his tenure in India in 1902 was considered the master of Indo-Saracenic architecture .

The main door of Senate House faces the Centenary buildings and opens to the Great Hall (150 feet long, 60 feet wide and 50 feet high from boarded floor to ornate, canvas ceiling). It was here that convocations were once held, here that students in robes and academic caps celebrated in jubilation before the University expanded and convocations were held at the Centenary auditorium across the road. When the first Assembly was constituted in 1937, it was here that it met.

Senate03CF27feb2019

Light from the evening sun filters through the arcaded verandahs supported by stone capitals with Indian figurines. The red hand-pressed brick is firm to the touch and cool despite the searing heat. Broomhall’s tiles cover the roofs from where pigeons fly out to wheel over the Bay and back. Windows — shuttered, vertical and circular — covered in stained glass and woodwork lend it the solemn air of a cathedral. Mooresque colours dominate the walls and lecture halls on the floor above are accessed through grand stairways. The minarets and porches lend it a fabled feel. From the star-embossed stone porches one can see the almost-forgotten statue of Queen Victoria seated shrouded under a canopy of wild bushes. Gazing at the sea and the cars parked in front of it with its back to Senate House is the statue of S Subramania Aiyar, first Indian Vice Chancellor.

On the day I visit, work is in progress for the Biennale. The clickety-clack of a typewriter from the Publications office on the ground floor echoes through the hall. Workers erect installations and artists are at work. Dust dances in the sunbeams that light up the floor and lends Senate Hall a touch of fast-fading old world grace. Go before its doors close and its beauty blushes unseen.

‘Free kick’ and a social goal

Kicking their way to a better future; (inset) Ajit Sigamani.
Kicking their way to a better future; (inset) Ajit Sigamani.

By offering a no-cost programme, mixed martial arts trainer Ajit Sigamani seeks to improve the lot of underprivileged youngsters

Ajit Sigamani equips underprivileged youngsters for the battles ahead of them. How does he do that? By helping them deliver a punch here and a kick there. Punches and kicks usually don’t enter polite conversations, and so, before you let your imagination run away with you, here is the drift of it.

Ajit is a combat sports coach and the founder of a combat training club called Combat Kinetics (CK), and he provides free training in mixed martial arts (MMA) to such youngsters so that they carve out a career in martial arts, as coaches or as competition-level fighters.

Thirty-five years old now, Ajit was initiated into combat training at age eight, when he was enrolled for a Karate programme and from there, he went on to train in boxing, sambo, judo and Indian martial arts. (Ajit is the vice-president of the Sambo Federation of India)

With such grounding in mixed martial arts, Ajit started Combat Kinetics in 2011. The training at CK, Ajit says, is mobility-based and combines many sports. “Fitness and weight-loss are an natural by products,” he adds.

“Under a programme ‘Fight For Your Future’, we take care of not just the coaching, but also the nutritional needs of the students,” he says.

Ajit says that at the end of the programme, students either choose to become coaches or participate in tournaments around the world; and many have also been selected to University programmes and even landed jobs under the sports quota, on account of their MMA background.

Syed Abdul Nazzeur (Abu), started his MMA career at a time when his family was facing a financial crisis.

“I didn’t even eat properly during that time and my coach helped me get good food, the needed nutrition, the best training and now I have risen to a level where I train police officers and they call me ‘coach’. I even acquired English and soft skills training for free.”Abu won the first International medal for India in MMA in China in 2016, and now serves as a coach at CK.

Navya Rao, a graphic designer, tattoo artist and a former coach at CK, states that training in MMA builds one’s confidence.

CK has eight centres in Chennai and expansion plans are on the cards.

How Chennai-based Nutpam is using virtual reality to upskill professionals

Nutpam builds virtual reality-driven training content for people working in large corporations and sectors like healthcare and education. Its VR simulators train people to not just learn but also get used to machines. 

When we hear the term virtual reality (VR), our first thought might be of a sci-fi movie or a video game. However, many people are now realising the application of immersive technology to skill people in various sectors such as healthcare and other industries to train people. With platforms such as IBCricket, which brings the popular sport to your living room, and VRDevotee, which lets you immerse yourself in devotion at any place, VR is also garnering a lot of attention in India.

Meanwhile, Senthil Sarguru and Karthik Bavanandan, both 28 years old, set up Nutpam in 2016 at Mylapore, a suburb in Chennai, which builds solutions using VR. Its product uses immersive technologies to train industrial labour, doctors and students. The team says it uses AR, VR, internet of things (IoT) and artificial intelligence (AI) to bring immersive experiences into the app or even into the physical world.

“We strongly believe that our strength is in content making for immersive experiences. We have been developing VR/AR content in healthcare, enterprise, education, and other immersive experiences based on the client’s requirement,” says Senthil.

Nutpam’s 10-member team has expertise in scripting, modelling as well as programming for virtual reality.

The early inspiration (and setbacks)

The founders say they were very inspired by Google and Facebook’s VR work. However, the team initially started off by offering 360-degree videography services for companies. But their common interest was VR technologies.

In 2016, when they were marketing their skills and looking for new projects, they were discovered by a client from Brazil. The project was about Human Anatomy VR training for medical students in Brazil. Hence, the trio bought their first VR hardware and began building modules, which they sold to the client in Brazil.

“For a year we were able to work on various 360 degree projects, and then we started using VR for companies,” says Senthil.

Simultaneously, they also started focusing at NGOs to deliver training and education to students using VR. Unfortunately, it did not work, and they ended up burning most of the money. Their first success came from one of the corporates, which asked the team to build a VR module to train employees to collaborate effectively. The results were good, and this deal proved to be lucky for Nutpam and it started making profits.

It is currently focusing on medical and industrial training with VR simulators. The founders claim that their unique selling proposition is integration of VR content, and leasing of VR headsets. The company presently competes with Tesseract, a Delhi-based startup which specialises in AR experiences.

The founders say it was challenging for them to find the right talent to build the technology, create image recognition, processing the content and regenerating a real world in the virtual world.

The training product 

Nutpam’s product aims to simplify the effort for its clients and builds virtual reality-driven content for training. For example, it provides simulators to people to get used to machines in a thermal power plant, and avoids the risk of training them in a live thermal station.

“This kind of simulator-based training will make a huge impact on the society because it can take risks off industrial training, and make people perfect with their skills,” says Senthil.

Similarly, in healthcare, if a trainee doctor needs to understand the different cases of polyps that grows in the gut, it can be created using virtual reality and the doctors can be trained to insert an endoscope and guided to lift tissues for biopsy.

The company also operates in industrial training, facility management training and construction. Some of its prominent clients include L&T, Uber and Swiggy. Apart from India, it has clients in the US and Brazil.

The numbers game in VR

According to the founders, Nuptam is yet to gain substantial revenues as it believes the market for virtual reality will only pick up from 2020. The company’s revenue at present is less than Rs 50 lakh, said one of the founders. “Our revenue model is a services model. For any client who wants R&D services for VR, we manage that,” says Senthil.

The company has so far raised $500,000 from an undisclosed angel investor. It aims to double its clients by 2020, and plans to increase its revenues to Rs 3 crore or more and also turn profitable in the coming years.

According to research firm Statista, the VR industry is growing at a fast pace globally. The market for virtual reality hardware and software is projected to increase from $2.2 billion in 2017, to more than $19 billion by 2020.

The world of virtual reality is filled with opportunities as it is a new area of interest for corporates to train its employees, to connect with consumers and also build immersive content. As India is brimming with ideas about changing the nature of reality itself, it is only a matter of time before people end up living their digital avatars, and less of their human self.

Historian’s contributions to T.N.’s social history hailed

HistoryCF10feb2019

Speakers discuss A.R. Venkatachalapathy’s writings

Tracing the journey of historian and author A.R. Venkatachalapathy, speakers discussed his contributions to the social and cultural history of Tamil Nadu at a seminar on Saturday.

Organised jointly by KalachuvaduKadavu, and The Hindu Lit for Life, the second day of ‘Viruvum Aazhamum’ seminar had sessions on Mr. Venkatachalapathy’s many avatars as historical researcher, translator, author, teacher and scholar.

Tamil writer Perumal Murugan said Mr. Venkatachalapathy had compiled and brought out 17 books, including ones on freedom fighter V.O. Chidambaram Pillai, poet Bharathiyar and Tamil writers Maraimalai Adigal and Pudhumaipithan, to fill gaps in historical accounts. He also threw light on lesser-known personalities like A.K. Chettiyar, a Tamil travelogue writer, and contributed to new perspectives in history, he added.

Style of writing

Speakers also discussed his style of writing and his contributions to the literary field through prefaces and Dalit writings. His prefaces were distinct and could be compiled and published as books, some of the speakers said. Describing his captivating style of writing as more typical of fiction, speakers suggested that he write a book tracing the history of Tamil proverbs.

Mr. Venkatachalapathy has published 41 books in English and Tamil and has authored about 200 articles in various newspapers and magazines.

He is currently a professor at the Madras Institute of Development Studies.

IIT-M research generates lasers from carrots

Carrots cooked in alcohol may soon be a popular source of lasers.

Chennai :

Carrots cooked in alcohol may soon be a popular source of lasers. Researchers from the Indian Institute of Technology-Madras (IIT-M) have demonstrated the possibility of generating laser in an eco-friendly way, by using carrots as a lasing material, according to a statement issued by the institute.
The laser, generated through this technique, has immense potential in the field of bio-imaging.

Currently, the most common lasing materials, such as Indium-Gallium-Arsenic and Gallium-Nitrates, are manufactured using toxic chemical processes which are harmful to the environment. The new technique that the researchers have come up with uses just minimally processed carrots.“We fondly call this kitchen laser,” exclaimed Sivarama Krishnan, one of the guides of the research.

The research was undertaken by a team comprising Prof C Vijayan, Assistant Professor Sivarama Krishnan, and Venkata Siva Gummaluri, a PhD research scholar, from the Physics department of IIT-M.
The discovery itself was a result of the after-work-hours fun experiment, said Sivarama Krishnan. “We were pumping light through various organic materials and found that carrots have lasing properties. For example, we also tried orange juice and tomato juice,” he said. What set the humble carrot apart was the optically active bio-pigment called carotenoids present in the vegetable.

Although the fluorescence quantum yield of carotenoids is much less, compared to standard organic laser dyes, the vibrational spectra can be obtained even with extremely low concentrations of carotenoids, said Sivarama Krishnan. “We could easily increase the concentration of caretenoids on the surface of the carrots, by simply cooking it in alcohol. Then we pump light through a slice of the surface to get laser,” he said.

While the traditional polymers used were toxic and non-biodegradable, there has been search for more eco-friendly fluorescent polymers. In this search, the team looked at biological molecules as probable lasing sources.

Speaking about the importance of this research, Vijayan said, “There is now a move towards development of green, sustainable materials for various applications, including in photonics. The need for green photonic technologies is obvious in the current times where sustainability, bio-compatibility and degradability are of paramount importance.”

Carrots, in addition to having carotenoids, also have cellulose fibres that contribute to multiple scattering of photons and resultant optical amplification for Raman random lasing. The demonstration uses a process, first discovered by CV Raman, who won the Nobel Prize for Physics in 1930.

The researchers plan to advance their research to make the material more commercially viable. Currently, this material has potential as it is natural, bio-compatible, safe to handle and highly reliable.
