!!Something about GOOGLE!!



Google Inc. is a publicly traded company. Their stock is listed on Nasdaq under the symbol GOOG.Google is a play on the word googol, which was coined by Milton Sirotta, nephew of American mathematician Edward Kasner, and was popularized in the book, Mathematics and the Imagination by Kasner and James Newman. It refers to the number represented by the numeral 1 followed by 100 zeros. Google's use of the term reflects the company's mission to organize the immense, seemingly infinite amount of information available on the web.

Back before Google? Aye, there's the Rub.

According to Google lore, company founders Larry Page and Sergey Brin were not terribly fond of each other when they first met as Stanford University graduate students in computer science in 1995. Larry was a 24-year-old University of Michigan alumnus on a weekend visit; Sergey, 23, was among a group of students assigned to show him around. They argued about every topic they discussed. Their strong opinions and divergent viewpoints would eventually find common ground in a unique approach to solving one of computing's biggest challenges: retrieving relevant information from a massive set of data.

By January of 1996, Larry and Sergey had begun collaboration on a search engine called BackRub, named for its unique ability to analyze the "back links" pointing to a given website. Larry, who had always enjoyed tinkering with machinery and had gained some notoriety for building a working printer out of Lego™ bricks, took on the task of creating a new kind of server environment that used low-end PCs instead of big expensive machines. Afflicted by the perennial shortage of cash common to graduate students everywhere, the pair took to haunting the department's loading docks in hopes of tracking down newly arrived computers that they could borrow for their network.

A year later, their unique approach to link analysis was earning BackRub a growing reputation among those who had seen it. Buzz about the new search technology began to build as word spread around campus.

The search for a buyer

Larry and Sergey continued working to perfect their technology through the first half of 1998. Following a path that would become a key tenet of the Google way, they bought a terabyte of disks at bargain prices and built their own computer housings in Larry's dorm room, which became Google's first data center. Meanwhile Sergey set up a business office, and the two began calling on potential partners who might want to license a search technology better than any then available. Despite the dotcom fever of the day, they had little interest in building a company of their own around the technology they had developed.

Among those they called on was friend and Yahoo! founder David Filo. Filo agreed that their technology was solid, but encouraged Larry and Sergey to grow the service themselves by starting a search engine company. "When it's fully developed and scalable," he told them, "let's talk again." Others were less interested in Google, as it was now known. One portal CEO told them, "As long as we're 80 percent as good as our competitors, that's good enough. Our users don't really care about search."

Touched by an angel

Unable to interest the major portal players of the day, Larry and Sergey decided to make a go of it on their own. All they needed was a little cash to move out of the dorm - and to pay off the credit cards they had maxed out buying a terabyte of memory. So they wrote up a business plan, put their Ph.D. plans on hold, and went looking for an angel investor. Their first visit was with a friend of a faculty member.

Andy Bechtolsheim, one of the founders of Sun Microsystems, was used to taking the long view. One look at their demo and he knew Google had potential - a lot of potential. But though his interest had been piqued, he was pressed for time. As Sergey tells it, "We met him very early one morning on the porch of a Stanford faculty member's home in Palo Alto. We gave him a quick demo. He had to run off somewhere, so he said, 'Instead of us discussing all the details, why don't I just write you a check?' It was made out to Google Inc. and was for $100,000."

The investment created a small dilemma. Since there was no legal entity known as "Google Inc.," there was no way to deposit the check. It sat in Larry's desk drawer for a couple of weeks while he and Sergey scrambled to set up a corporation and locate other funders among family, friends, and acquaintances. Ultimately they brought in a total initial investment of almost $1 million.

Everyone's favorite garage band

In September 1998, Google Inc. opened its door in Menlo Park, California. The door came with a remote control, as it was attached to the garage of a friend who sublet space to the new corporation's staff of three. The office offered several big advantages, including a washer and dryer and a hot tub. It also provided a parking space for the first employee hired by the new company: Craig Silverstein, now Google's director of technology.

Already Google.com, still in beta, was answering 10,000 search queries each day. The press began to take notice of the upstart website with the relevant search results, and articles extolling Google appeared in USA TODAY and Le Monde. That December, PC Magazine named Google one of its Top 100 Web Sites and Search Engines for 1998. Google was moving up in the world.


On the road again

We quickly outgrew the confines of our Menlo Park home, and by February 1999 had moved to an office on University Avenue in Palo Alto. At eight employees, the staff had nearly tripled, and the service was answering more than 500,000 queries per day. Interest in the company had grown as well. Red Hat signed on as its first commercial search customer, drawn in part by Google's commitment to running its servers on the open source operating system Linux.

On June 7, the company announced that it had secured a round of funding that included $25 million from the two leading venture capital firms in Silicon Valley, Sequoia Capital and Kleiner Perkins Caufield & Byers. In a replay of the convergence of opposites that gave birth to Google, the two firms - normally fiercely competitive, but eye-to-eye on the value of this new investment - both took seats on the board of directors. Michael Moritz of Sequoia and John Doerr of Kleiner Perkins - who between them had helped grow Sun Microsystems, Intuit, Amazon, and Yahoo! - joined Ram Shriram, CEO of Junglee, at the ping pong table that served as formal boardroom furniture.

In short order, key hires began to fill the company's modest offices. Omid Kordestani left Netscape to accept a position as vice president of business development and sales, and Urs Hölzle was hired away from UC Santa Barbara as vice president of engineering. It quickly became obvious that more space was needed. At one point the office became so cramped that employees couldn't stand up at their desks without others tucking their chairs in first. No beta search engine
The gridlock was alleviated with the move to the Googleplex, our new headquarters in Mountain View, California. And tucked away in one corner of the two-story structure, the Google kernel continued to grow - attracting staff and clients and drawing attention from users and the press. AOL/Netscape selected Google as its web search service and helped push traffic levels past 3 million searches per day. Clearly, we had evolved. What had been a college research project was now a real company offering a service that was in great demand. So on September 21, 1999, the beta label came off Google.com.

Still we continued to expand. The Italian portal Virgilio signed on as a client, as did Virgin Net, the UK's leading online entertainment guide. The spate of recognition that followed included a Technical Excellence Award for Innovation in Web Application Development from PC Magazine and inclusion in several "best of" lists, culminating with Google's appearance on Time magazine's Top Ten Best Cybertech list for 1999.
Built-in innovation
At the Googleplex, a unique company culture was evolving. To maximize the flexibility of the work space, large rubber exercise balls were repurposed as highly mobile office chairs in an open environment free of cubicle walls. While computers on the desktops were fully powered, the desks themselves were wooden doors held up by pairs of sawhorses. Lava lamps began sprouting like multi-hued mushrooms. Large dogs roamed the halls - among them Yoshka, a massive but gentle Leonberger. After a rigorous review process, Charlie Ayers was hired as company chef, bringing with him an eclectic repertoire of health-conscious recipes he developed while cooking for the Grateful Dead. Sections of the parking lot were roped off for twice-weekly roller hockey games. Larry and Sergey led weekly TGIF meetings in the open space among the desks, which easily accommodated the company's 60-odd employees.

The informal atmosphere bred both collegiality and an accelerated exchange of ideas. Google staffers made many incremental improvements to the search engine itself and added such enhancements as the Google Directory (based on Netscape's Open Directory Project) and the ability to search via wireless devices. Google also began thinking globally, with the introduction of our first 10 language versions for users who preferred to search in their native tongues.

We love you, Google users!Google's features and performance attracted new users at an astounding rate. The broad appeal of Google search became apparent when the site was awarded both a Webby Award and a People's Voice Award for technical achievement in May 2000. Sergey's and Larry's five-word
Google Search, Gmail, Google Documents and all other Google services are owned by a company called Google Inc. It is a company with stocks, you can buy a part of Google Inc. yourself.

Some Famous Scientist of INDIA.





#1.Sir Jagadish Chandra Bose (1858-1937): 
J a g a d i s h C h a n d r a B o s e w a s b o r n o n 3 0 N o v e m b e r 1 8 5 8 , i n Myemsingh, Faridpur, a part of the Dhaka District now in Bangladesh. He attended the village school till he was 11. He then moved to Kolkata where he enrolled in St. Xavier’s. He was very much interested in Biology. However, Father Lafont, a famous Professor of Physics, inspired in Bose a great interest in Physics. Having obtained his B.A. in physical sciences, twenty two year old Bose left for London, to obtain a medical degree. However, he kept falling ill and had to discontinue his plans to be a doctor. He then obtained his B.A. degree from Christ College, Cambridge.He returned to India in 1885 and joined Presidency College, Kolkata as an Assistant Professor of Physics, where he remained till 1915. There was a peculiar practice in the college at that time. The Indian teachers in the college were paid one third of what the British eachers were paid! So Bose refused his salary but worked for three years. The fourth year he was paid in full! He was an excellent teacher, extensively using scientific demonstrations in class. Some of his students, such as S. N. Bose went on to become famous physicists themselves.During this
iod, Bose also started doing original scientific work in the a r e a of mi c rowave s , c a r rying out expe r iment s involving r e f r a c t ion, diffraction and polarization. He developed the use of galena crystals for making receivers, both for short wavelength radio waves and for white and ultraviolet light. In 1895, two years before Marconi’s demonstration, Bose demonstrated wireless communication using radio waves, using them to ring a bell remotely and to explode some gunpowder. Many of the microwave components familiar today - waveguides, horn antennas, polarizers, dielectric lenses and prisms, and even semiconductor detectors of electromagnetic radiation - were invented and used by Bose in the last decade of the nineteenth century. He also suggested the existence of electromagnetic radiation from the Sun, which was confirmed in 1944.

Bose then turned his attention to response phenomena in plants. He showed that not only animal but vegetable tissues, produce similar electric response under different kinds of stimuli – mechanical, thermal, electrical and chemical.Bose was knighted in 1917 and soon thereafter elected Fellow of the Royal Society, London, (both as physicist and biologist!). Bose had worked
all along without the right kind of scientific instruments and laboratory. For a long time he had been thinking of building a laboratory. The result was the establishment of the Bose Research Institute in Kolkata. It continues to be a famous centre of research in basic sciences.

#2.Prafulla Chandra Ray (1861-1944): Prafulla Chandra was born on 2 August 1861 in Raruli-Katipara, a village in the District of Khulna (in present day Bangladesh). His early education started in his village school. He often played truant and spent his time resting comfortably on the branch of a tree, hidden under its leaves. After attending the village school, he went to Kolkata, where he studied at Hare School and the Metropolitan College. The lectures of Alexander Pedler in the Presidency College, which he used to attend, attracted him to chemistry, although his first love was literature. He continued to take interest in literature, and taught himself Latin and French at home. After obtaining a F.A. diploma from the University of Calcutta, he proceeded to the University of Edinburgh on a Gilchrist scholarship where he obtained both his B.Sc. and D.Sc. degrees.

In 1888, Prafulla Chandra made his journey home to India. Initially he spent a year working with his famous friend Jagadish Chandra Bose in his laboratory. In 1889, Prafulla Chandra was appointed an Assistant Professor of Chemistry in the Presidency College, Kolkata. His publications on mercurous nitrite and its derivatives brought him recognition from all over the world. Equally important was his role as a teacher - he inspired a generation of young
chemists in India thereby building up an Indian school of chemistry. Famous Indian scientists like Meghnad Saha and Shanti Swarup Bhatnagar were among his students. Prafull Chandra believed that the progress of India could be achieved only by industrialization. He set up the first chemical factory in India, with very minimal resources, working from his home. In 1901, this pioneering effort resulted in the formation of the Bengal Chemical and Pharmaceutical Works Ltd.

He retired from the Presidency College in 1916, and was appointed as Professor of Chemistry at the University Science College. In 1921 when Prafulla Chandra reached 60 years, he donated, in advance, all his salary for the rest of his service in the University to the development of the Department of Chemistry and to the creation of two research fellowships. The value of this endowment was about two lakh rupees. He eventually retired at the age of 75. In Prafulla Chandra Ray, the qualities of both a scientist and an industrial entrepreneur were combined and he can be thought of as the father of the Indian Pharmaceutical industry.

#3.Srinivasa Ramanujan (1887-1920): Ramanujan was born in Erode, a small village in Tamil Nadu on 22 December 1887. When he was a year old his family moved to the town of Kumbakonam, where his father worked as a clerk in a cloth merchant’s shop. When he was nearly five years old, Ramanujan enrolled in the primary school. In 1898 he joined the Town High School in Kumbakonam. At the Town High School, Ramanujan did well in all subjects and proved himself an able all round scholar. It was here that he came across the book Synopsis of Elementary Results in Pure Mathematics by G. S. Carr. Influenced by the book, he began working on mathematics on his own, summing geometric and arithmetic series. H e w a s g i v e n a s c h o l a r s h i p t o t h e G o v e r n m e n t C o l l e g e i n Kumbakonam. However his scholarship was not renewed because Ramanujan neglected all subjects other than mathematics.


In 1905 he appeared for the First Arts examination which would have allowed him to be admitted to the University of Madras. Again he failed in all subjects other than mathematics, a performance he repeated in 1906 and 1907 too. In the following years he worked on mathematics, with only Carr’s book as a guide, noting his results in what would become the famous Notebooks.
He got married in 1909 and started looking for a job. His search took him to many influential people, among them Ramachandra Rao, one of the founding members of the Indian Mathematical Society. For a year he was supported by Ramachandra Rao who gave him Rs. 25 per month. He started posing and solving problems in the Journal of the Indian Mathematical Society.


His research paper on Bernoulli numbers, in 1911, brought him recognition and he became well known in Chennai as a mathematical genius. In 1912, with Ramachandra Rao’s help, he secured the post of clerk in the accounts section of the Madras Port Trust. He continued to pursue mathematics and in 1913 he wrote to G. H. Hardy in Cambridge, enclosing a long list of his own theorems. Hardy immediately recognized Ramanujan’s mathematical ability. On the basis of Hardy’s letters, Ramanujan was given a scholarship by the University of Madras in 1913. In 1914, Hardy arranged for him to go to Trinity College, Cambridge. Ramanujan’s work with Hardy produced important results right from the beginning. In 1916 Ramanujan graduated from Cambridge with a Bachelor of Science by Research. In 1918, he was elected a Fellow of the Cambridge Philosophical Society, a Fellow of the Royal Society of London, and a Fellow of Trinity College, Cambridge, all in the same year! However, from 1917 onwards he was seriously ill and mostly bedridden. In 1919 he returned to India, in very poor health. Ramanuj an made out s t anding cont r ibut ions to ana lyt i c a l number theory, elliptic functions, continued fractions, and infinite series. His published and unpublished works have kept some of the best mathematical brains in the world busy to this day. 


#4.Sir Chandrasekhara Venkata Rama (1888-1970) : Chandrasekhara Venkata Raman was born at Tiruchirapalli in Tamil Nadu on 7 November 1888. His father was a lecturer in mathematics and p h y s i c s s o f r om t h e v e r y b e g i n n i n g h e wa s imme r s e d i n a n a c a d emi c atmosphere. Raman’s academic brilliance was established at a very young age. He finished his secondary school education at the tender age of thirteen
and entered the Mrs. A.V.N. College at Vishakapatnam, Andhra Pradesh. Two years later he moved to the prestigious Presidency College in Chennai.When he was fifteen, he topped his class to receive his B.A. degree with honours in Physics and English. Raman continued his studies at the Presidency College and when he was barely eighteen, graduated at the top of his class and received his M.A. degree with honours. Raman joined the Indian Audit and Accounts Service and was appointed the Assistant Accountant General in the Finance Department in Kolkata. In Kolkata, he sustained his interest in science by working in the laboratory of the Indian Association for the Cultivation of Science, in his spare time studying the physics of stringed instruments and Indian drums. In 1917, Raman gave up hi s gove rnment job to be come the Sir Taraknath Palit Professor of Physics at the Science College of University of Calcutta (1917-33). He made enormous contributions to research in the areas o f    v i b r a t i o n , s o u n d , m u s i c a l i n s t r u m e n t s , u l t r a s o n i c s , d i f f r a c t i o n ,photoelectricity, colloidal particles, X-ray diffraction, magnetron, dielectrics, etc. In particular, his work on the scattering of light during this period brought him world-wide recognition.

In 1924 he was elected a Fellow of the Royal Society of London and a year later was honoured with the prestigious Hughes medal from the Royal Society. Four years later, at the joint meeting of the South Indian Science Association and the Science Club of Central College, Bangalore, he announced his discovery of what is now known as the Raman Effect. He was knighted in 1929, and in 1930, became the first Asian scientist to be awarded the Nobel Prize for Physics for his discoveries relating to the scattering of light (the Raman Effect). In 1934, he became the Director of the newly established Indian Institute of Science at Bangalore, where he remained
till his retirement. After retirement, he established the Raman Research Institute at Bangalore, where he served as the Director. The Government of India conferred upon him its highest award,the Bharat Ratna in 1954.


#5.Meghnad Saha(1893-1956):  Meghnad Saha was born on 6 October 1893 in Sheoratali village near Dhaka in present day Bangladesh. His father Jagannath Saha was a grocer in the village. After primary education, he was admitted to a middle school that was seven miles away from home. He stayed with a doctor near the school and had to work in that house to pay for his boarding and lodging. Overcoming all these difficulties, he stood first in the Dhaka middle school test, thus securing a Government scholarship and joined the Dhaka Collegiate school.

in 1905.Great political unrest was prevailing in Bengal, caused by the partition of the province by the British against strong popular opinion. Meghnad Saha was among the few senior students who staged a boycott of the visit by the then Governor, Sir Bampfylde Fuller and as a consequence forfeited his scholarship and had to leave the institution. He then joined the Kisori Lal Jubilee School where he passed the entrance test of the University of Calcutta standing first among students from East Bengal. He graduated from Presidency College with mathematics as his major. He then joined the newly established Science College in Kolkata as a lecturer and pursued his research activities in physics. By 1920, Meghnad Saha had established himself as one of the leading physicists of the time. His theory of high-temperature ionization of elements and its application to stellar atmospheres, as expressed by the Saha equation, is fundamental to modern a s t rophys i c s ; subs equent deve lopment of hi s ide a s ha s l ed to inc r e a s ed knowledge of the pressure and temperature distributions of stellar atmospheres.

In 1920, Saha went to Imperial College, London and later to Germany.Two years later he returned to India and joined the University of Calcutta as Khaira Professor. He then moved to the University of Allahabad and remained there till 1938, establishing the Science Academy in Allahabad (now known as the National Academy of Science). In 1927, he was elected a Fellow of the Royal Society of London. He returned to the University of Calcutta in 1938 where he introduced nuc l e a r phys i c s into the pos t -gr adua t e phys i c s cur r i culum. In 1947 he established the Indian Institute of Nuclear Physics (now known as the Saha Institute of Nuclear Physics). Later in his life, Saha played an active role in the development of scientific institutions throughout India as well as in national economic planning involving technology.




#6.Satyendra Nath Bose(1894-1974): Satyendra Nath Bose was born on New Years day, 1894 in Goabagan in Kolkata. His father was an accountant in Indian Railways. Satyendra Nath popularly known as Satyen Bose, did his schooling at Hindu School, Kolkata,and then joined Presidency College. He excelled in academics throughout his education – Intermediate, B.Sc. and M.Sc. with applied mathematics. His teacher at the Presidency College was Jagadish Chandra Bose - whose other stellar pupil was Meghnad Saha. Bose took his B.Sc. examination in 1913 and his M.Sc examination in 1915. He stood first in both the examinations, the second place going to Meghnad Saha. He worked as a lecturer of physics in the Science College of the University of Calcutta (1916-21) and along with Meghnad Saha, introduced postgraduate courses in modern mathematics and physics. He derived with Saha, the Saha-Bose equation of state for a nonideal gas.

In 1921, Bose left Kolkata to become a Reader at the Dakha University. It was during this eriod that he wrote the famous paper on the statistics of photons. It was named Bose statistics after him and is now an integral part of physics. Paul Dirac, the legendary physicist, coined the term boson for particles obeying these statistics. Apart from this he did theoretical work on the general t h e o r y o f r e l a t i v i t y a n d a l s o e x p e r i m e n t a l w o r k o n c r y s t a l l o g r a p h y, fluorescence, and thermoluminescence. Bose spent about 10 months in Paris in 1924, doing research with Madame Curie and Louis de Broglie. Later he went to Berlin where he met Einstein. He returned to Dhaka in 1926 and became Professor. Shortly before Independence, Bose returned to Kolkata to become the Khaira Professor of Physics, a post he kept till 1956. He was elected Fellow of the Royal Society in 1958, and the government of India named him a National Professor and awarded him the honor of Padma Vibhushan. 


#7.Shanti Swarup Bhatnagar (1894-1955): Bhatnagar was born on 21 February 1894 at Bhera, in the district of Shapur in Punjab (now in Pakistan). When he was barely eight months old,his father passed away. He spent his next thirteen years under the care of his maternal grandfather in Bulandshahar in Uttar Pradesh. Under the influence of his grandfather, young Bhatnagar not only developed a taste for engineering and science but also became interested at a very early age in geometry and algebra and in making mechanical toys. In 1911, Shanti published a letter to the editor, in The Leader, Allahabad, on how to make a substitute for carbon electrodes in a battery using molasses and carbonaceous matter under pressure and heat. Matriculating the same year, he joined the Dayal Singh College, Lahore. After finishing his intermediate examination in first division, Shanti joined the Forman Christian College and after his B.Sc and M.Sc degrees, he spent the next two years at the University of London earning his D.Sc. degree on the surface tension of oils, under the supervision of Professor F.G. Donnan. Returning to India in 1921, he joined the Benares Hindu University as a Professor, remaining there till 1924. From 1924 to 1940 he served as the Director of the University Chemical Laboratories, Lahore, addressing problems in industrial and applied chemistry.

In August 1940, Bhatnagar took over as the Director of the newly created Directorate of Scientific and Industrial Research. This organisation became the Council of Scientific and Industrial Research, with Bhatnagar as its Director. Bhatnagar’s tenure saw the setting up of 12 laboratories and the total number of CSIR laboratories today stands at 40. The British Government conferred on him the Order of the British Empire and in 1941, he was made the Knight Bachelor. In 1943 he was elected a Fellow of the Royal Society and received the Padma Vibhushan (1954) from the Government of India. Shanti Swarup Bhatnagar played a significant part along with Homi Bhabha , Pr a s ant a Chandr a Maha l anobi s , Vikr am Sa r abha i and othe r s in building of post-independence Science & Technology infrastructure and in
the formulation of India’s science policies.


#8.Homi Jehangir Bhabha (1909-1966): Homi Bhabha was born on 30 October 1909 in Mumbai. Son of a barrister, he grew up in a privileged environment. In Mumbai he attended the Cathedral & John Connon School and then Elphinstone College, followed by the Royal Institute of Science. After passing the Senior Cambridge Examination at the age of sixteen, he joined the Gonvile and Caius College in Cambridge with an intention to pursue mechanical engineering. His mathematics tutor
wa s P a u l Di r a c , a n d B h a b h a b e c ame f a s c i n a t e d wi t h ma t h ema t i c s a n d theoretical physics. He earned his engineering degree in 1930 and Ph.D. in 1934.

In 1937, together with W. Heitler, a German physicist, Bhabha solved the riddle about cosmic rays. Cosmic rays are fast moving, extremely small particles coming from outer space. When these particles enter the earth’s atmosphere, they collide with the atoms of air and create a shower of electrons. Bhabha’s discovery of the presence of nuclear particles (which he called mesons) in these showers was used to validate instein’s theory of relativity making him world famous. When the war broke out in Europe, Bhabha was on a holiday in India.

In 1940, C.V. Raman, then head of the Physics Department, Indian Institute of Science, Bangalore, persuaded Bhabha to join the institute as a Reader in Physics and Bhabha decided to stay back in India. In 1941, Homi Bhabha was elected Fellow of the Royal Society, London, in recognition of his contributions to the field of cosmic rays, elementary particles and quantum mechanics. Bhabha soon r e a l i z ed the ne ed for an ins t i tut e ful ly devot ed to fundamental research, and wrote to J.R.D. Tata for funding. This resulted in the establishment of the Tata Institute of Fundamental Research (TIFR) in Mumbai in 1945, with Bhabha as the Director, a position he held until his death. In 1948, Homi Bhabha was appointed the Chairman of the International Atomic Energy Commission. Under his guidance, nuclear reactors like the Apsara, Cirus and Zerlina were built. He gained international recognition for his excellent work and served as the President of the first United Nations Conference on the Peaceful Uses of Atomic Energy, which was held in Geneva in 1955. He was the President of the International Union of Pure and Applied Physics from 1960 to 1963. A multi-faceted personality, Bhabha was immensely fond of music, painting and writing. Some of his paintings are displayed in the British Art Galleries and the TIFR art collection today is rated as one of the best collections of contemporary Indian art in the country. He is the recipient of the Adam’s Award, Padma Bhushan, an Honorary Fellow of the American Academy of Arts and Sciences and Foreign Associate of the National Academy of Sciences in the United States.




#9.Subramaniam Chandrasekhar(1910-1995):Subramaniam Chandrasekhar, a nephew of Sir C.V. Raman, was born on 19 October 1910 in Lahore, (now in Pakistan). His father was an officer in the Department of Audits and Accounts of the Indian Government Services. Chandrasekhar received his elementary education from his parents and private tutors when he was in Lahore. In 1918 Chandra moved to Chennai where he attended the Hindu High School finishing his secondary school education with honours. He then joined the Presidency College, there taking his Bachelor of
Science degree in physics with honours. His first scientific paper, Compton Scattering and the New Statistics,was published in the Proceedings of the Royal Society in 1928. On the basis
of this paper he was accepted as a research student by R.H. Fowler at the University of Cambridge. On the voyage to England, he developed the theory of white dwarf stars, showing that a star of mass greater than 1.45 times the mass of the sun could not become a white dwarf. This limit is now known as the Chandrasekhar limit. He obtained his doctorate in 1933. Soon after receiving his doctorate, C h a n d r a s e k h a r wa s awa r d e d t h e P r i z e F e l l ows h i p a t Tr i n i t y C o l l e g e , Cambridge. In 1937, he accepted the position of Research Associate at the Unive r s i ty of Chi c ago. Chandr a s ekha r s t ayed a t Unive r s i ty of Chi c ago throughout his career, becoming the Morton D. Hall Distinguished Service Professor in Astronomy and Astrophysics in 1952. In 1952 he established the
Astrophysical Journal and was its editor for 19 years, transforming it from a local publication of the University of Chicago into the national journal of the American Astronomical Society. He became a US citizen in 1958. He was elected Fellow of the Royal Society of London and in 1962
received the Society’s Royal Medal. He also received the US National Medal of Science (1966). He was awarded the Nobel prize for Physics in 1983 for his theoretical work on the physical processes of importance to the structure of stars and their evolution. Chandra was a popular teacher who guided over fifty students to their Ph.D.s including some who went on to win the Nobel prize themselves!! His research explored nearly all branches of theoretical astrophysics and he published ten books, each covering a different topic, including one on the relationship between art and science.



#10.Vikram Sarabhai (1919-1971): Vikram Sarabhai was born on 12 August 1919 at Ahmedabad. He had hi s e a r ly education in a private school , ‘Retreat’ run by his parents on Montessori lines. This atmosphere injected into the young boy the seeds of scientific curiosity, ingenuity and creativity. With a natural inclination towards physics and mathematics, Vikram Sarabhai did not get into his family business.After school and college in Gujarat, he went to England and obtained his tripos at St. John’s College in 1939. He returned to India for a while and worked alongside Sir C.V. Raman in the field of cosmic rays, at the Indian Institute of Science in Bangalore, after which he returned to Cambridge, England for further research in the area and completed his Ph.D. in 1947. He established the Physical Research Laboratory in Ahmedabad in 1948, in a few rooms at the M.G. Science Institute with Professor K.K. Ramanathan as Director. In April 1954, PRL moved into a new building and Dr. Sarabhai made it the cradle of the Indian Space Programme. At the young age of 28, he was asked to organise and create the ATIRA, the Ahmedabad Textile Industry’s Research Association and was its Honorary Director during 1949-56. He also helped build and direct the Indian Institute of Management, Ahmedabad from 1962-1965. Sarabhai pioneered India’s space age by expanding the Indian Space Research Organization. India’s first satellite Aryabhata launched in 1975, was one of the many projects planned by him. Like Bhabha, Sarabhai wanted the practical application of science to reach the common man. Thus he saw a golden opportunity to harness space science to the development of the country in the fields of communication, meteorology, remote sensing and education.

The Satellite Instructional Television Experiment (SITE) launched in 1975-76, brought education to five million people in 2,400 Indian villages. In 1965,he established the Community Science Centre in Ahmedabad with a view to popularise science among children. His deep cultural interests led him, along with his wife Mrinalini Sarabhai, to establish Darpana Academy, an institution devoted to performing arts and propagation of ancient culture of India.He was the recipient of the Bhatnagar Memorial Award for Physics in 1962, the Padma Bhushan in 1966, and was posthumously awarded the Padma Vibhushan. He was the Chairman of the Atomic Energy Commission in 1966, Vice-President and Chairman of the UN Conference on peaceful uses of outer space in 1968, and President of the 14th General Conference of the International Atomic Energy Agency. The International Astronomical Union named a crater in the moon (in the Sea of Serenity) after him, in honour of his contributions to science.
