THE HEART OF FLAME - BROMELIA BALANSAE




It has been a scorching summer this year in Namm Ooru Bengaluru and bidding adieu to the summer are these stunning blooms of the “Bromelia balansae” or the “Heart of Flame”, plants.

 These plants are often grown as hedge plants because of their almost impenetrable razor sharp leaves, because of which they often referred to as the "Barbed-Wire-Fence-Bromeliad".






 Come summer and these often ignored hedge plants begin to blossom with the leaves turning bright vermillion red and from the center rises, the inflorescence filled with lovely lavender colored flowers, truly a stunning sight to behold.

A CENTURY AND MORE MAY 27, 2020 INDIAN INSTITUTE OF SCIENCE TURNS 111

A CENTURY AND MORE
MAY 27, 2020
INDIAN INSTITUTE OF SCIENCE TURNS 111


Architectural Plan of the IISc Main Building (Architect Charles F Stevens)




May 4th 2020 was a landmark day for the Indian Institute of Science (IISc), Bangalore,
IISc opened its Covid-19 testing laboratory, the first Research and Educational Institute in the Country to do so. A happy coincidence, since IISc was founded in May, to be precise on May 27, 1909.
Leading from the front, IISc has initiated several timely research and technology development projects to address the problems arising from the current Covid-19 pandemic. These include the development of - 3D printed Valves for split use of Ventilators to serve multiple patients, Oxygen Generator, Drones for disinfection, CovidWatch a monitoring tool for regions with low smartphone penetration and many more. A complete list of innovations are available at IISc's Covid-19 website.
Mr. Jamsetji Nusserwanji Tata would have been proud of the contributions of the Faculty and Students of the Indian Institute of Science, Bangalore, for their efforts in furthering the frontiers of Science and Technology for the benefit of humankind.

The Beginning: Indian Institute of Science

Jamsetji Nusserwanji Tata (1839-1904) was a true visionary, who even before the dawn of the 20th century, understood that the progress of this country depended crucially on higher education. Almost alone in his generation, he realized that if the economic foundations of Indian society were to be secure, science and technology must be harnessed to utilize the vast natural resources of our country.

The Indian Institute of Science owes its origin to the patriotic and far-sighted businessperson who was convinced of the need for a national level institution devoted to original investigations in all branches of learning and their applications for the benefit of humanity in general and India in particular.
A century and more later, IISc has evolved into India’s premier center for research and postgraduate education in science and engineering in the Country, an Institute tempered by history and time and yet retained its position as an “Institution of Excellence”.
The Institute occupies nearly 400 acres of prime land in Bangalore, generously donated by the His Highness Nalawadi Krishnaraja Wodeyar the then Maharaja of Mysore in March 1907.

Indeed the contribution from the Princely State of Mysore was the decisive element in determining the location of J.N.Tata’s proposed Institute in the city of Bangalore. Mention must be made of the contribution of Dewan K.Seshadri Iyer who ably assisted the Maharaja on this issue. Among the many factors that favoured Bangalore were its salubrious climate, availability of abundant natural mineral resources and unlimited power from the Shivasamudram Power Station.

            J.N.Tata did not want his name to be associated with the Institute; his dream was to create an institution that would contribute to the development of India. The name Indian Institute of Science was finally chosen, reflecting in every way the wishes of its Founder.


Morris Travers First Director of IISc

With the appointment of Morris Travers as the Institute’s First Director in 1906, the process of implementing Jamsetji’s vision began in full swing and the dream of one man with a vision in the 1890’s, finally came true when the Vesting Order of the establishment of the Institute was issued on May 27, 1909.


The Institute began with two departments (1) General and Applied chemistry and (2) Electro Technology and the first batch of students were admitted into the Institute in 1912.

The departments of Organic Chemistry and Biochemistry were soon added. Early research work in these departments focused on several local industrial problems – such as sandalwood oil extraction, setting up of an Acetone factory and a Lac manufacturing unit and more.

The Growth:
             As the Institute has grown, several new areas of research have been added in tune with changing times. The Institute’s departments in fields ranging from Aerospace Engineering and High Voltage Engineering to Biochemistry have served to nucleate research and development in both the public and private sectors in the country. The Central Power Research Institute (CPRI) Bangalore, the Hindustan Aeronautics Limited (HAL) Bangalore, the National Aerospace Laboratories (NAL) Bangalore, the National Centre for Biological Sciences (NCBS), the Central Food and Technological Research Institute (CFTRI) Mysore,  and the Karnataka Soaps and Detergents Limited, Bangalore, to name a few, owe their origin to the Institute.

The faculty and alumni of the Institute have been responsible for establishing and spearheading many new Institutions and programs across the country.  Homi Bhabha conceived of the idea of the Tata Institute of Fundamental Research (TIFR) while working at IISc’s Department of Physics.  Vikram Sarabhai, the founder of India’s space program worked under Prof C V Raman at IISc.

The indigenously developed Light Combat Aircraft (LCA)-TEJAS had its origins at IISc. Scientists at the Aerospace Engineering Department designed, developed and tested the first Radio Controlled model of the LCA at IISc’s airfield.

Many of India’s most distinguished scientists have been associated with the Institute.  Notable among them are G. N. Ramachandran, Harish Chandra, Satish Dhawan, Arcot Ramachandran, Roddam Narasimha and C. N. R. Rao. A large number of the alumni of the Institute have gone on to head several major Organizations, Institutions and Companies both in India and abroad.

            In the century that has passed since its inception. IISc has grown to become India’s premier centre for Research and Post-Graduate Education in Science and Engineering. The evolution of the Institute over the past one hundred and Eleven years has mirrored the development of Science and Technology in India.

Then and Now:

IISc in its new avatar emphasizes “Discover and Innovate; Transform and Transcend; Serve and Lead” and towards this endeavor, IISc has initiated many new academic programs; notable among them are the interdisciplinary Ph.D. programs in Mathematical Sciences, Chemical Biology, Earth Sciences, Nanoscience, Nanotechnology and Nano-engineering for Integrated Systems. An M.Tech program in Climate Science and new Centers for Earth Sciences and Climate Change and an M.Tech in Artificial Intelligence (AI), A Centre for Science and Policy and a Department of Computational and Data Sciences.
IISc has a Faculty/Scientific Staff strength of around 500 and a student population of around 4200, of which there are about 2700 doctoral students, 1000 Master’s students in the engineering disciplines, and about 450 students pursuing BSc (Research), a four-year, research-oriented undergraduate programme in the sciences.
IISc has several on-going research collaborations with Universities/Institutions/Companies, both from within the Country and Abroad and is one of the premier institutions in the world with more than a hundred illustrious years of history in the creation of original knowledge for furthering the frontiers of Science and Technology for the benefit of humankind.

A silken connection to Bangalore and IISc was established early in its history with the setting up of the Tata Silk Farm and when the elder son of J. N. Tata – Mr. Dorab Tata, married a Bangalore girl - Meherbai the daughter of H. J. Bhabha the then Inspector General of Education in  Mysore and Coorg.

BUTTERFLY FLOWER ORCHID - Papilionanthe teres - IISc



BUTTERFLY-FLOWER ORCHID

Papilionanthe teres



The 400 acre wooded campus of the Indian Institute of Science in Bangalore, India, is “A Botanist’s Delight” and during a recent visit, I captured this image of a rare Orchid blooming at the Horticultural Nursery and Gardens there.



Unable to identify the Orchid, I sent in a couple of photographs to The Orchid Society of Karnataka (TOSKAR) and bingo came the reply from Ravee of TOSKAR, who identified it as the Papilionanthe orchid. Thank you Ravee.


Searching the internet, I gathered that this is the Papilionathe teres species and was first described by German Botanist, Taxonomist and Orchid expert Friedrich Richard Rudolf Schlechter in 1915. He derived the name from the Latin – papilio (for butterfly) and anthe (for flower), to describe the colorful butterfly like flowers of this plant.


Papilionanthe teres


Papilionanthe teres occurs widely in Southeast Asia, East of Nepal, Bhutan and North East India, Anandaman and Nicobar Islands, Myanmar, Thailand, Laos, Vietnam and southern China.
The Papilionanthe blooms in summer with showy fragrant flowers. The flowers vary in size (5-10 cm in diameter) and color. They are usually pale pink or pink with a dark pink lip and a yellow center.

THE AMAZING FLOWERS IN THE NATURAL WORLD: THE NAGALINGA PUSHPA

THE AMAZING FLOWERS  IN THE NATURAL WORLD:
THE NAGALINGA PUSHPA 


It’s summer here in Namma Ooru Bengaluru and it’s that time of the year when the air is filled with the heavenly fragrance of one of Nature's most beautiful of flowers the Nagalinga Pushpa - the flowers of the Cannonball tree (Botanical Name: Couroupita guianensis). These tall trees are in full bloom with hundreds of attractive sweet smelling flowers. 






Nature is not in LOCKDOWN and for those lucky residents in Malleshwaram, Basavanagudi, RMV (Raj Mahal Vilas) Second Stage, Infantry Road and of course the Lalbagh Botanical Gardens (temporarily closed), the IISc campus and many other localities in the city, it’s a sight to behold.

The Cannonball Tree:
Couroupita guianensis is native to the rainforests of  Central and South America and it is cultivated in many other tropical areas throughout the world because of its beautiful, fragrant flowers and large, interesting fruits There are medicinal uses for many parts of Couroupita guianensis, and the tree has cultural and religious significance in  India Sri Lanka, and Southeast Asia.
Couroupita guianensis grows up to 35 meters in height, flowers are born in large bunches up to 10 meters in length, most trees flower profusely, until the entire trunk is buried in flowers, one tree can bear 1000 or more flowers.



The odd feature of the Cannonball tree is that its flowers and fruits grow from woody extrusions from the trunk of the tree and carry bulbous buds and fragrant six-petalled scarlet/orange flowers.
Another oddity are the fruits of this tree, which are spherical with a woody shell and reach diameters up to 25 centimeters or about 10 inches in diameter, giving the species the name Cannonball tree. 



          The tree was named Couroupita guianensis by the French botanist Jean Baptiste Christophore Fusée Aublet in 1755. 

The Nagalinga Pushpa:





A rarity in nature are the flowers of the Cannonball tree, no other flower has such a stunning formation of its Stigma, Stamens and Petals.               The Stamens of the flower seem to represent the 1000-headed Cobra Snake in Hindu Mythology, protecting the Shiva Linga - the Stigma; the flower base comprises of pink or red petals that resemble the Lotus. The petals are scarlet on the inside with a white base and yellow inside. There are two sets of stamens. The first is the infertile set and the second is the fertile set. The flower has no nectar and uses the pollen in the infertile exposed stamens to attract bees.

In India the flower is known by many names:
In Hindi - Shiv Kamal/Shivaling/Kailaspati. Nagalingam in Tamil and Nagkeshar in Bengali. Nagalinga Pushpa in Kannada; Nagalingam in Malayalam; Nagamalli flowers or Mallikarjuna flowers in Telugu.
Hindus revere it as a sacred tree because the petals of the flower resemble the hood of the Naga, a sacred snake, protecting a Shiva Lingam, the stigma.  These trees are extensively grown in Shiva temples in India.
