National Mathematics Day 2022 celebrates on 22 December
National Mathematics Day 2022:
National Mathematics Day is celebrated on December 22 across the nation every year. The National Mathematics Day is marked to recognise and celebrate the works of Srinivasa Ramanujan. Srinivasa Ramanujan, the Indian mathematical genius, was born on this day in 1887. This year nation celebrates his 135th birth anniversary of Ramanujan. The main objective behind the celebration of National Mathematics Day is to make people aware of the development of mathematics and its importance in the growth of humanity.
National Mathematics Day: History
The day was announced on 26 February 2012 by the then Prime Minister Manmohan Singh to mark the 125th anniversary of the birth of the Indian mathematical genius Srinivasa Ramanujan (22 Dec 1887- 26 Apr 1920). 2012 was also observed as National Mathematics Year. Ramanujan had a wealth of ideas that have transformed and reshaped 20th-century mathematics. These ideas continue to shape the mathematics of the 21st century.
Important points on life and work of the Srinivasa Ramanujan:
- Srinivasa Ramanujan was born on December 22, 1887, in Tamil Nadu’s Erode to a Brahmin Iyengar family. He had developed a liking for mathematics at a very young age, mastering trigonometry at 12 and was eligible for a scholarship at the Government Arts College in Kumbakonam.
- He studied at the Government College in Kumbakonam in 1903. Due to his dislike for non-mathematical subjects, he failed exams there. He had enrolled in Madras’ Pachaiyappa College at the age of 14.
- In 1912, Ramanujan started working as a clerk in the Madras Port Trust. There, his mathematical genius was recognised by some of his colleagues and one of them referred him to Professor GH Hardy of Trinity College, Cambridge University. He met Hardy in 1913, after which he went to Trinity College.
- In 1916, Ramanujan received his Bachelor of Science (BSc) degree. He went on to publish several papers on his subject with Hardy’s help. The two even collaborated on several joint projects.
- Ramanujan was elected to the London Mathematical Society in 1917. Next year, he was elected to the prestigious Royal Society for his research on Elliptic Functions and theory of numbers. He was also the first Indian to be elected a Fellow of the Trinity College.
- Despite not receiving any formal training in pure maths, Ramanujan made impactful contribution to the discipline in his short life. His areas of work include infinite series, continued fractions, number theory and mathematical analysis.
- He also made notable contributions like the hypergeometric series, the Riemann series, the elliptic integrals, the theory of divergent series, and the functional equations of the zeta function. He is said to have discovered his own theorems and independently compiled 3,900 results.
- In 1919, Ramanujan returned to India. A year later, on April 26, he breathed his last owing to deteriorating health. He was just 32 years old. His biography ‘The Man Who Knew Infinity’ by Robert Kanigel depicts his life and journey to fame.
- A film of the same name was released in 2015 in which British-Indian actor Dev Patel played Ramanujan. The 2015 movie ‘The Man Who Knew Infinity” was released based on Srinivasa Ramanujan’s biography. The film shed light on Ramanujan’s childhood in India, his time in Britain, and his journey to becoming the great mathematician.
World Bank hints that Global Economy on a steep Slowdown
Global Economy on a steep Slowdown: According to the most recent World Bank study, the global economy is experiencing a sharp decline after almost a year of uncertainty in 2022. The World Bank report noted that the COVID-19 pandemic’s repercussions are still being felt today in the form of education losses, worldwide inflation, supply chain disruptions, and other issues on a global scale.
Global Economy on a steep Slowdown: Key Points
- The global economy is currently experiencing its steepest slowdown after a post-recession recovery since 1970, according to the report 2022 in Nine Charts, which also discussed growth.
- Global consumer confidence has already fallen significantly more sharply than it did in the years leading up to previous global recessions.
- The economy of the three biggest economies in the world—the United States, China, and the euro zone—have been rapidly slowing.
- It went on to say that given the situation, even a slight blow to the world economy over the course of the ensuing year may send it into a recession.
- In its study, the World Bank also noted that the escalating intensity of natural disasters continues to shed light on the social and economic effects of climate change.
