November 7, 2013 is the 125th birth anniversary of one of India's most prominent scientists CV Raman and Google has highlighted on its India home page the work for which the physicist won a Nobel. The postage-stamp-like Google doodle celebrating CV Raman's birthday has Sir Chandrasekhara Venkata Raman's (his full name) face appearing behind the letter G and on the adjacent stamp to the right the other letters in the Google logo demonstrate the Raman effect.
It was in 1928 that he discovered the phenomenon now called Raman scattering that is the result of the Raman effect.
Definition of Raman effect on Encyclopedia Britinnica: When a beam of light traverses a dust-free, transparent sample of a chemical compound, a small fraction of the light emerges in directions other than that of the incident (incoming) beam. Most of this scattered light is of unchanged wavelength. A small part, however, has wavelengths different from that of the incident light; its presence is a result of the Raman effect. Raman was knighted by the British monarch in 1929. He received the Nobel Prize for Physics in 1930, becoming the second Indian Nobel laureates after Rabindranath Tagore. In 1933 CV Raman joined the Indian Institute of Science, at Bangalore and headed of the department of physics. He was named director of the Raman Research Institute in 1947.
After India's Independence CV Raman was instrumental in setting up of other prominen.

Google doodle celebrates C V Raman birthday (Sir Chandrasekhara Venkata Raman)
Biography of C V Raman:-
Chandrasekhara Venkata Raman was born at Trichinopoly in Southern India on November 7th, 1888. His father was a lecturer in mathematics and physics so that from the first he was immersed in an academic atmosphere. He entered Presidency College, Madras, in 1902, and in 1904 passed his B.A. examination, winning the first place and the gold medal in physics; in 1907 he gained his M.A. degree, obtaining the highest distinctions.
His earliest researches in optics and acoustics - the two fields of investigation to which he has dedicated his entire career - were carried out while he was a student.
Since at that time a scientific career did not appear to present the best possibilities, Raman joined the Indian Finance Department in 1907; though the duties of his office took most of his time, Raman found opportunities for carrying on experimental research in the laboratory of the Indian Association for the Cultivation of Science at Calcutta (of which he became Honorary Secretary in 1919).
In 1917 he was offered the newly endowed Palit Chair of Physics at Calcutta University, and decided to accept it. After 15 years at Calcutta he became Professor at the Indian Institute of Science at Bangalore (1933-1948), and since 1948 he is Director of the Raman Institute of Research at Bangalore, established and endowed by

Educational tools adorn the Google home page on Friday in honour of the Italian educator Maria Montessori on her 142nd birth anniversary.
Montessori is best known for developing an educational system that bears her name and is practised in thousands of schools around the world. The Montessori system of education tries to uncover a child's creative potential and gives emphasis on independence.
Born on August 31, 1870, Maria Montessori was the first Italian woman to get a degree in medicine. She graduated from the University of Rome in 1896.
In 1907 she opened her first preschool for children and its success led to the opening of other Montessori schools. She travelled to different countries, including India, to disseminate her educational system. Maria Montessori was in India from 1939 to 1946.
On May 6, 1952, Montessori died of a cerebral haemorrhage in the Netherlands. She was 81.

To mark the 193rd birth anniversary of Clara Schumann, the German musician and composer, Google has posted a new doodle on its homepage.
The doodle features Clara Schumann playing the piano, with her eight children clinging to her, thereby replacing the two O's and the second G of the Google logo. The colours of the doodle are in sync with Google's official logo colours - blue, red, yellow and green.
Born on 13 September 1819, Clara Schumann was raised by her father. Her parents divorced when Clara was only four years old.
In March 1828, whe she was eight years old, Clara performed at the Leipzig home of Dr Ernst Carus, director of a mental hospital at Colditz Castle, and met Robert Schumann, who was nine years older than her. Schumann admired Clara's performance and so much that he asked permission from his mother to discontinue his studies of the law, and take music lessons with Clara's father, Friedrich Wieck. She later married him.
Clara made her public debut in a concert in the Leipziger Gewandhaus at the age of 9. She was acknowledged throughout Europe as a phenomenally talented child prodigy. She was also instrumental in transforming the kind of programs expected of concert pianists.
At the age of 18, Clara Wieck performed a series of recitals in Vienna from December 1837 to April 1838. Clara Schumann's reputation brought her into contact with the leading musicians of the day.
In 1839, Robert Schumann a

Google's latest doodle celebrates the 165th birthday of Bram Stoker, the Irish novelist and short story writer best known as the creator of Dracula, despite writing 19 books.
Born in Dublin in 1847, Stoker studied at Trinity College while working as a civil servant in Dublin Castle and moonlighting as a newspaper drama critic.
He moved to London in 1878 with his new wife, Florence Balcombe, and became an administrator of the Irving Company at the Lyceum theatre.
Stoker's first full-length book, written earlier in Dublin, was a piece on non-fiction entitled The Duties of Clerks of Petty Sessions in Ireland, and was followed by novels, lectures, short stories, articles, serials and a two-volume memoir of Irving.
Dracula, his fifth novel, was published in 1897 after Stoker spent several years researching European folklore and mythological stories of vampires.
He died in London in 1912 after suffering a number of strokes. One hundred years after Stoker's death, Dracula continues to fascinate and forms the basis for a film and literary industry based around vampires.
A new edition, with an introduction by the Irish writer Colm Tóibín, was published this year to mark the centenary of Stoker's death.

From the first program that Ada Lovelace created for the Analytical Engine to present day laptops and tablet PCs, Google has doodled the evolution of computers on the occasion of the world's first computer programmer's 197th birth anniversary.
The doodle shows Ada Lovelace writing the pioneering computer program with a quill pen seated on a desk and the paper scroll she is writing her algorithm on twirls in the shape of the letters of the Google logo.
Ada King, the countess of Lovelace, was born on December 10, 1815 in Piccadilly Terrace, Middlesex, England and was the daughter of the famous poet Lord Byron, but as her parents separated soon after her birth and she did not get to know her father well.
Her original name was Augusta Ada Byron and on her marriage to William King she became Ada King and later her husband became an earl, she became the countess of Lovelace.
While she was educated at home by tutors, her mathematical skills were further honed by Augustus De Morgan, the first professor of mathematics at the University of London, who helped her in advanced studies.
Her association with Charles Babbage, father of the computer, began when she translated an article by Italian mathematician and engineer Luigi Federico on Babbage's proposed Analytical Engine. She not only translated the work but added her notes that were more elaborate and longer than the work she was translating.
Ada Lovelace died at the young age o

Google, today, commemorates Mary Leakey's 100th birthday anniversary with an attractive doodle. Leakey, a renowned British archaeologist and anthropologist, was born on February 6, 1913 in London, England and is well known for her significant discoveries and exploring the fossils of the ancient hominines. She collaborated with her husband Louis Leakey through a large part of her career and her three sons also entered the same field. She died on December 9, 1996 at the age of 83.
Leakey's discoveries included the fossilised Proconsul skull, an extinct ape that is believed to be ancestor to humans. Another discovery was that of the Zinjanthropus skull, an early hominin, at Olduvai Gorge. She is also credited with developing a system to classify stone tools found at Olduvai as well as discovering Laetoli footprints. Over the course of her career, Leakey wrote four books.
Her passion towards unearthing the fossils was somewhat influenced by John Frere, an antiquarian, and Sheppard Frere, an archaeologist. Moreover, she had a chance to accompany Elie Peyrony during an excavation at Les Eyzies, where she came across collection scrapers and other tools from the dump. It is believed that at this phase her interest in prehistory gradually sparked.

Commemorating the 100th birthday of the British archaeologist and anthropologist Mary Leakey, Google has posted a doodle on its homepage. The doodle features Mary Leakey on an archaeological site, who looks busy with her excavation work.
The doodle features two Dalmatians as Mary was an animal lover who was almost always accompanied in the field by three or four dalmatians. It also exhibits one of her major discoveries 'the Laetoli footprints', and some tools used in archaeology.
The first and last two letters of the word Google are seen in the backdrop, while Mary Leakey and one of the Dalmatians replace the second O and second G of the word Google, respectively.
Born on February 6 1913, Mary Leakey is widely known for discovering the first fossilised Proconsul skull, an extinct ape now believed to be ancestral to humans, and the robust Zinjanthropus skull at Olduvai Gorge.
Along with her husband Louis Leakey, Mary uncovered the tools and fossils of ancient hominines. She is also credited for developing a system for classifying the stone tools found at Olduvai, and discovering the Laetoli footprints, which received recognition by the public for providing convincing evidence of bipedalism in Pliocene hominids.
In 1933, she was a 20-year-old archaeological illustrator in London when she met Louis Leakey. A married man with two children, Leakey left his family to begin a new life with Mary that revolved around the search for the orig

n one of its best doodles so far, Google has honoured ace graphic designer Saul Bass on what would have been his 93rd Birthday. Bass is the name behind some of Hollywood and the Western world’s most iconic logos and designs.
The doodle is animated elaborately and features sections on some of Bass’ most loved and remembered credit sequence designs including Anatomy of a Murder and Vertigo. The video is set to the tune of a jazz piece, reminiscent of the old world charms of American cinema.
Why opening sequences? Bass was responsible for revolutionising the way credits were shown before movies in the US. Before Bass, credits were usually simply projected on to the screen. With his innovative designs, he put up credits against an animated backdrop, changing the way opening sequences were perceived in Hollywood.
Bass worked with some of the biggest names in Hollywood like Alfred Hitchcock, Stanley Kubrick, Martin Scorsese and Billy Wilder. In his career that spanned over 40 years, he designed opening sequences for North by Northwest, Psycho, Vertigo, Ocean’s 11 and Goodfellas.
He also designed iconic logos for AT&T Corporation, Girl Scouts of the USA, NCR Corporation, Quaker Oats and more.
Born into a Jewish immigrant family in New York in 1920, Bass studied art part-time at the Art Students League in Manhattan. He started off in Hollywood by doing print work for ads at the age of 20 until he collaborated w
