Partition of Bengal 1905: Reasons, Consequences, Objectives, When the Partition was Canceled, Partition Movement, Swadeshi Movement

CV Raman was a prominent scientist in contemporary India who made significant contributions to science. As a result of his unique discoveries, he gave India a new identity in science. The 'Raman Effect' was one of the most notable and important discoveries of CV Raman, for which he was awarded the Nobel Prize in 1930.

 

Biography of CV Raman

 

“When light travels through any transparent medium such as a solid, liquid or gas, it is said to modify its nature and behavior.”

If CV Raman had not made this discovery, we would never have understood "why the color of seawater is blue," and we would never have known about the "nature and behavior of light." Hold on for now as we will look into more aspects of his work, contribution, and journey later in this article.

Early life

V Raman was born on November 7, 1888 in Tiruchirappalli, Tamil Nadu. Chandrasekhara Iyer and Parvathi Amma were the names of his mother and father. CV Raman is the second child of his parents. CV Raman's father Chandrasekhara Iyer was a science and mathematics instructor at AV College. Narasimha Rao College, Visakhapatnam (modern Andhra Pradesh). His father was very fond of reading, so he built a small library in his house. At an early age, Raman was attracted to science books and English literature. His love for music began at an early age and developed into the subject of his scientific studies. His father was an accomplished veena player whom he would watch for hours while his father practiced the instrument. As a result, Raman started off in a good learning environment.

Education

Raman went to Visakhapatnam in his childhood. He went to St. Aloysius Anglo-Indian High School there. Raman was a brilliant student who received many honors and scholarships in his class. At the age of 13, he passed matriculation in 11th and completed +2/intermediate with a scholarship only in 13.

After that in 1902, he enrolled in the Presidency College, Madras. In 1904 CV graduated with a B.A. Passed. Examination He was awarded the 'Gold Medal' for coming first in Physics. Thereafter, he did his MA from Presidency College, with Physics as his primary subject. MA Raman rarely attended class during this period, preferring to spend his time experimenting and making discoveries in the college laboratory.

His lecturers were fully aware of his abilities and allowed him to study at his own convenience. Professor R Ali. Jones recommended that he should write the results of his experiments and studies in the form of a "research paper" and send it to the London-based "Philosophical Journal". In November 1906, their study report was published in the November edition of the journal. At that time his age was only 18 years. He completed his M.A. in 1907. Got excellent marks on the exam.

Livelihood

Raman's coaches recommended that his father send him to England for higher studies, but he could not do so due to ill health. He had no choice at this time, so he appeared in a competitive exam conducted by the British government. Raman stood first in this examination and was appointed as an officer in the finance department of the government. In Kolkata, Raman was promoted to the post of Assistant Accountant General and set up a small laboratory in his home.

 

He continued his work in the laboratory of the Indian Association for Cultivation of Science in Kolkata. He used to do scientific studies on anything that caught his attention. He used to reach the council laboratory every morning before work. After work at five in the evening, he would return to the laboratory and work there until ten. Even on Sundays, he spends the whole day in the laboratory working on his studies and research.

Raman left his government job in 1917 to take up the Palit Chair in Physics from the 'Indian Association for Cultivation of Science'. In 1917, he was appointed as a Professor of Physics at the University of Calcutta. Raman was elected as a member of the 'Royal Society' of London in 1924 for his contribution to the subject of 'Optics', a great distinction for any scientist.

The 'Raman Effect' was established on February 28, 1928. The next day, Raman disclosed this to the international press. The famous scientific journal 'Nature' published it. He gave a speech on his new discoveries on March 16, 1928, at the South Indian Science Association in Bangalore. After this, research on 'The Raman effect' started in all the laboratories around the world.

Venkata Raman also presided over the Indian Science Congress in the year 1929. He was awarded the prestigious Nobel Prize in Physics in 1930 for his discovery of the scattering of light and the Raman effect.

In 1934, Raman was made the director of the Indian Institute of Science, Bangalore. He was the one to uncover the harmonic nature of Tabla and Mridangam. He also researched the spectral nature of stills, fundamental issues of still dynamics, the structure and properties of diamonds, and the optical behavior of many colorless substances. In 1948, he retired from the Indian Institute of Science (IIS). Thereafter, he established the Raman Research Institute in Bangalore.

Personal Life: Wife and Children

CV Raman was attracted to a girl named Lokasundari while playing the veena and expressed his intention to marry her. With the consent of the family, he married her on May 6, 1907. They have two sons Radhakrishnan and Chandrasekhar. His son Radhakrishnan became a famous astronomer.

Awards and honors

India's greatest scientist Chandrasekhara Venkata Raman (CV Raman) was also honored with many honors for his significant contribution to science, which we will discuss below:-

•       In 1924, scientist CV Raman was elected as a member of the 'Royal Society of London'.

•       On February 28, 1928, CV Raman discovered the 'Raman Effect' and the Government of India declared that day as 'National Science Day'.

•       CV Raman received several medals, prestigious degrees, and royalties from various institutions in 1929 for his various experiments and achievements.

•       For scientific breakthroughs such as dispersion and the 'Raman Effect', he was awarded the Nobel Prize in 1930, an outstanding and prestigious honor.

•       He was also awarded India's highest civilian award, the Bharat Ratna in 1954 for his heroic death.

Death

The brilliant scientist CV Raman spent most of his time in the laboratory making new discoveries and gathering information. Probably at the age of 82, he was working in his laboratory at the Raman Research Institute in Bangalore, when on November 21, 1970, he suddenly suffered a heart attack, fell unconscious, and passed away.

Conclusion

CV Raman The scientist who brought India-wide fame in the field of science, Raman may not be with us anymore, but his essential discoveries will always be with us; His extraordinary findings are still used extensively today. The way he helped in the development of science through his efforts and hard work through discoveries like the 'Raman Effect', is a matter of joy for all Indians. The personality of CV Raman will be carried on for generations to come.
