SRINIVASA RAMANUJAN HISTORY


Srinivasa Ramanujan Biography







Born: December 22, 1887
Died: April 26, 1920
Achievements: Ramanujan independently discovered results of Gauss, Kummer and others on hypergeometric series. Ramanujan's own work on partial sums and products of hypergeometric series have led to major development in the topic. His most famous work was on the number p(n) of partitions of an integer n into summands.

Srinivasa Ramanujan was a mathematician par excellence. He is widely believed to be the greatest mathematician of the 20th Century. Srinivasa Ramanujan made significant contribution to the analytical theory of numbers and worked on elliptic functions, continued fractions, and infinite series.

Srinivasa Aiyangar Ramanujan was born on December 22, 1887 in Erode, Tamil Nadu. His father worked in Kumbakonam as a clerk in a cloth merchant's shop. At the of five Ramanujan went to primary school in Kumbakonam. In 1898 at age 10, he entered the Town High School in Kumbakonam. At the age of eleven he was lent books on advanced trigonometry written by S. L. Loney by two lodgers at his home who studied at the Government college. He mastered them by the age of thirteen. Ramanujan was a bright student, winning academic prizes in high school.

At age of 16 his life took a decisive turn after he obtained a book titled" A Synopsis of Elementary Results in Pure and Applied Mathematics". The book was simply a compilation of thousands of mathematical results, most set down with little or no indication of proof. The book generated Ramanujan's interest in mathematics and he worked through the book's results and beyond. By 1904 Ramanujan had begun to undertake deep research. He investigated the series (1/n) and calculated Euler's constant to 15 decimal places. He began to study the Bernoulli numbers, although this was entirely his own independent discovery. He was given a scholarship to the Government College in Kumbakonam which he entered in 1904. But he neglected his other subjects at the cost of mathematics and failed in college examination. He dropped out of the college.

Ramanujan lived off the charity of friends, filling notebooks with mathematical discoveries and seeking patrons to support his work. In 1906 Ramanujan went to Madras where he entered Pachaiyappa's College. His aim was to pass the First Arts examination which would allow him to be admitted to the University of Madras. Continuing his mathematical work Ramanujan studied continued fractions and divergent series in 1908. At this stage he became seriously ill again and underwent an operation in April 1909 after which he took him some considerable time to recover.

On 14 July 1909 Ramanujan marry a ten year old girl S Janaki Ammal. During this period Ramanujan had his first paper published, a 17-page work on Bernoulli numbers that appeared in 1911 in the Journal of the Indian Mathematical Society. In 191,1 Ramanujan approached the founder of the Indian Mathematical Society for advice on a job. He got the job of clerk at the Madras Port Trust with the help of Indian mathematician Ramachandra Rao.

The professor of civil engineering at the Madras Engineering College C L T Griffith was interested in Ramanujan's abilities and, having been educated at University College London, knew the professor of mathematics there, namely M J M Hill. He wrote to Hill on 12 November 1912 sending some of Ramanujan's work and a copy of his 1911 paper on Bernoulli numbers. Hill replied in a fairly encouraging way but showed that he had failed to understand Ramanujan's results on divergent series. In January 1913 Ramanujan wrote to G H Hardy having seen a copy of his 1910 book Orders of infinity. Hardy, together with Littlewood, studied the long list of unproved theorems which Ramanujan enclosed with his letter. Hardy wrote back to Ramanujan and evinced interest in his work.

University of Madras gave Ramanujan a scholarship in May 1913 for two years and, in 1914, Hardy brought Ramanujan to Trinity College, Cambridge, to begin an extraordinary collaboration. Right from the start Ramanujan's collaboration with Hardy led to important results. In a joint paper with Hardy, Ramanujan gave an asymptotic formula for p(n). It had the remarkable property that it appeared to give the correct value of p(n), and this was later proved by Rademacher.

Ramanujan had problems settling in London. He was an orthodox Brahmin and right from the beginning he had problems with his diet. The outbreak of World War I made obtaining special items of food harder and it was not long before Ramanujan had health problems.

On 16 March 1916 Ramanujan graduated from Cambridge with a Bachelor of Science by Research. He had been allowed to enrol in June 1914 despite not having the proper qualifications. Ramanujan's dissertation was on Highly composite numbers and consisted of seven of his papers published in England.

Ramanujan fell seriously ill in 1917 and his doctors feared that he would die. He did improve a little by September but spent most of his time in various nursing homes. On February 18, 1918 Ramanujan was elected a fellow of the Cambridge Philosophical Society and later he was also elected as a fellow of the Royal Society of London. By the end of November 1918 Ramanujan's health had greatly improved.

Ramanujan sailed to India on 27 February 1919 arriving on 13 March. However his health was very poor and, despite medical treatment, he died on April 6, 1920.

MEGHNAD SAHA HISTORY


Meghnad Saha Biography







Born: October 6, 1893
Died: February 16, 1956
Achievements: Made outstanding contribution to the field of Astrophysics. He put forward an "ionization formula" which explained the presence of the spectral lines.

Meghnad Saha was an outstanding Indian scientist. He made remarkable contribution to the field of Astrophysics.

Meghnad Saha was born on October 6, 1893 in Sheoratali, a village in the District of Dacca, now in Bangladesh. He was the fifth child of his parents, Sri Jagannath Saha and Smt. Bhubaneshwari Devi. His father was a grocer in the village. Meghnad Saha had his early schooling in the primary school of the village. As his family could hardly able to make both ends meet, Meghnad Saha managed to pursue his schooling only due to the generosity of a local medical practitioner, Ananta Kumar Das, who provided him with boarding and lodging in his house.

In 1905, British Government took the decision of partition of Bengal. There was great political unrest in Bengal as popular opinion was against the partition. Sir Bampfylde Fuller was governor of East Bengal at that time. One day he came to visit the Collegiate school. Meghnad Saha along with other students boycotted his visit. As a result he was suspended from the school and his scholarship was terminated. He took admission in the Kishorilal Jubili School and passed the Entrance Examination of the Calcutta University in 1909, standing first among the student from East Bengal obtaining the highest marks in languages (English, Bengali and Sanskrit combined) and in Mathematics. In 1911, he ranked third in the ISc exam while the first position went to another great scientist Satyendranath Bose.

Meghnad Saha took admission in Presidency College Calcutta. In 1913 he graduated from Presidency College with Mathematics major and got the second rank in the University of Calcutta while the first one was taken by S.N. Bose. In 1915, both S.N.Bose and Meghnad Saha ranked first in M.Sc. exam, Meghnad Saha in Applied Mathematics and S.N. Bose in Pure Mathematics.

While studying in Presidency College, Meghnad got involved with Anushilan Samiti to take part in freedom fighting movement. He also came in contact with nationalists like Subhash Chandra Bose and Rajendra Prasad.

In 1917, Meghnad Saha joined as lecturer at the newly opened University College of Science in Calcutta. He taught Quantum Physics. Along with S.N. Bose, he translated the papers published in German by Einstein and Minkowski on relativity into English versions. In 1919, American Astrophysical Journal published - "On Selective Radiation Pressure and it's application" - a research paper by Meghnad Saha. He put forward an "ionization formula" which explained the presence of the spectral lines. The formula proved to be a breakthrough in astrophysics. He went abroad and stayed for two years. He spent time in research at Imperial College, London and at a research laboratory in Germany. In 1927, Meghnad Saha was elected as a fellow of London's Royal Society.

Meghnad Saha moved to Allahabad and in 1932 Uttar Pradesh Academy of Science was established. He returned to Science College, Calcutta in 1938. During this time Saha got interested in Nuclear Physics. In 1947, he established Institute of Nuclear Physics which later was named after him as Saha Institute of Nuclear Physics. He took the first effort to include Nuclear Physics in the curriculum of higher studies of science. Having seen cyclotrons used for research in nuclear physics abroad, he ordered one to be installed in the institute. In 1950, India had its first cyclotron in operation.

In 1952 he stood as an independent candidate for Parliament and was elected by a wide margin. He died on February 16, 1956 due to a heart attack.

JAGDISH CHANDRA BOSE HISTORY


Jagdish Chandra Bose Biography







Born: November 30, 1858
Died: November 23, 1937
Achievements: He was the first to prove that plants too have feelings. He invented wireless telegraphy a year before Marconi patented his invention.

Jagdish Chandra Bose was an eminent Indian scientist. He was the first to prove that plants and metals too have feelings.

Jagdish Chandra Bose was born on November 30, 1858 in Mymensingh (now in Bangladesh). His father Bhagabanchandra Bose was a Deputy Magistrate. Jagadish Chandra Bose had his early education in village school in Bengal medium. In 1869, Jagadish Chandra Bose was sent to Calcutta to learn English and was educated at St.Xavier's School and College. He was a brilliant student. He passed the B.A. in physical sciences in 1879.

In 1880, Jagdishchandra Bose went to England. He studied medicine at London University, England, for a year but gave it up because of his own ill health. Within a year he moved to Cambridge to take up a scholarship to study Natural Science at Christ's College Cambridge. In 1885, he returned from abroad with a B.Sc. degree and Natural Science Tripos (a special course of study at Cambridge).

After his return Jagadish Chandra Bose, was offered lectureship at Presidency College, Calcutta on a salary half that of his English colleagues. He accepted the job but refused to draw his salary in protest. After three years the college ultimately conceded his demand and Jagdish Chandra Bose was paid full salary from the date he joined the college. As a teacher Jagdish Chandra Bose was very popular and engaged the interest of his students by making extensive use of scientific demonstrations. Many of his students at the Presidency College were destined to become famous in their own right. These included Satyendra Nath Bose and Meghnad Saha.

In 1894, Jagadish Chandra Bose decided to devote himself to pure research. He converted a small enclosure adjoining a bathroom in the Presidency College into a laboratory. He carried out experiments involving refraction, diffraction and polarization. It would not be wrong to call him as the inventor of wireless telegraphy. In 1895, a year before Guglielmo Marconi patented this invention, he had demonstrated its functioning in public.

Jagdish Chandra Bose later switched from physics to the study of metals and then plants. He fabricated a highly sensitive "coherer", the device that detects radio waves. He found that the sensitivity of the coherer decreased when it was used continuously for a long period and it regained its sensitivity when he gave the device some rest. He thus concluded that metals have feelings and memory.

Jagdish Chandra Bose showed experimentally plants too have life. He invented an instrument to record the pulse of plants and connected it to a plant. The plant, with its roots, was carefully picked up and dipped up to its stem in a vessel containing bromide, a poison. The plant's pulse beat, which the instrument recorded as a steady to-and-fro movement like the pendulum of a clock, began to grow unsteady. Soon, the spot vibrated violently and then came to a sudden stop. The plant had died because of poison.

Although Jagdish Chandra Bose did invaluable work in Science, his work was recognized in the country only when the Western world recognized its importance. He founded the Bose Institute at Calcutta, devoted mainly to the study of plants. Today, the Institute carries research on other fields too.

Jagdish Chandra Bose died on November 23, 1937.

Add caption
     C.V RAMAN LIFE STORY
Born: November 7, 1888
Died: November 21, 1970
Achievements: He was the first Indian scholar who studied wholly in India received the Nobel Prize.

C.V. Raman is one of the most renowned scientists produced by India. His full name was Chandrasekhara Venkata Raman. For his pioneering work on scattering of light, C.V. Raman won the Nobel Prize for Physics in 1930.

Chandrashekhara Venkata Raman was born on November 7, 1888 in Tiruchinapalli, Tamil Nadu. He was the second child of Chandrasekhar Iyer and Parvathi Amma. His father was a lecturer in mathematics and physics, so he had an academic atmosphere at home. 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, C.V. Raman passed his M.A. obtaining the highest distinctions.

During those times there were not many opportunities for scientists in India. Therefore, Raman joined the Indian Finance Department in 1907. After his office hours, he carried out his experimental research in the laboratory of the Indian Association for the Cultivation of Science at Calcutta. He carried out research in acoustics and optics.

In 1917, Raman was offered the position of Sir Taraknath Palit Professorship of Physics at Calcutta University. He stayed there for the next fifteen years. During his tenure there, he received world wide recognition for his work in optics and scattering of light. He was elected to the Royal Society of London in 1924 and the British made him a knight of the British Empire in 1929. In 1930, Sir C.V. Raman was awarded with Nobel Prize in Physics for his work on scattering of light. The discovery was later christened as "Raman Effect".

In 1934, C.V. Raman became the director of the newly established Indian Institute of Sciences in Bangalore, where two years later he continued as a professor of physics. Other investigations carried out by Raman were: his experimental and theoretical studies on the diffraction of light by acoustic waves of ultrasonic and hypersonic frequencies (published 1934-1942), and those on the effects produced by X-rays on infrared vibrations in crystals exposed to ordinary light. In 1947, he was appointed as the first National Professor by the new government of Independent India. He retired from the Indian Institute in 1948 and a year later he established the Raman Research Institute in Bangalore, where he worked till his death.

Sir C.V. Raman died on November 21, 1970.
