(1) Srinivasa Ramanujan was a renowned Indian mathematician who made extraordinary contributions to mathematical analysis, number theory, infinite series, and continued fractions despite having little formal training in pure mathematics.
(2) He was born in 1887 in India and showed an extraordinary aptitude for mathematics from a young age, mastering advanced mathematical concepts including trigonometry at age 13.
(3) Ramanujan received recognition for his genius and was invited to study at Trinity College, Cambridge in England. However, he struggled with the climate and culture in England and his health declined, and he ultimately returned to India where he passed away in 1920 at the young age of 32.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

7. Srinivasa Ramanujan is known as an
all-time great Indian Mathematician
Born on 22 nd
December
1887,Erode,
Tamilnadu, India
7
8. Once his teacher said that when zero is
divided by any number, the result is
zero, Ramanujan immediately asked
his teacher, whether zero divided by
zero gives zero; This shows early signs
of his genius!
A thought of 7 years Old
Ramanujan

9. SCHOOL EDUCATION
Passed primary examination and
Stood first in the district at
Town high school-Kumbakonam
(1898).
Mastered advanced trigonometry
written by S. L. Loney at the age of
13 years.
9
10. Adulthood
He was a self-taught Mathematician.
He was really good at Maths so when he
took his exam, he passed in Maths, but
failed in other subjects because of his
disinterest. So , he couldn’t enter the
university of Madras for further studies.
He was married with a nine years old girl
named Janaki Ammal, when he was 22 but
he did not live with his wife till she reached
the age of 12.
Since he showed extraordinary talent by
himself, people around him helped to take
his achievements known to the other
Internationally renowned mathematicians .
10
11. He was invited to England to improve
his works by G.H.Hardy and J.E
Littlewood, who were great
mathematicians.
Hardy and Ramanujan had two
opposite personalities. As Hardy was
an atheist and believes mathematical
proof and analysis, Ramanujan was a
deeply religious guy and he believed in
his trustworthy intuition .
He was the first elected
Mathematician from India to the
London Mathematical society and he
became a Fellow of the Royal society.
11
12. Recognition of his
Genius
Initially, G. H. Hardy thought that the
works of Ramanujan were fraud because
most of them were impossible to believe.
But eventually ,they were convinced and
interested in his talent.

29. • Ramanujan and Hardy
arrived at Ramanujan’s
residence in a cab number
1729.
Hardy commented that the
number 1729 seemed to be
unintresting.
Ramanujan said that it is a
very intresting
mathematical number.

30. The smallest natural number can be
represented in two different ways as a sum
of two cubes:
1729=13 +123
=93 +103
It is also incidentally the product of three
prime numbers

36. TOUGH LIFE IN ENGLAND
Pure vegetarian meals was not
available.
Too busy with calculations and
very often neglected food and spent
till late night.
The cold and damp climate disturbed
his health.
He was attacked by Tuberculosis.
He returned to India.

37. We Miss a Great Mathmatician
• Ramanujan sailed to Indian on
27 February 1919 and arrived
on 13 march
However his health was very
poor.
He passed away on 26th April
1920 at Kumbakonam(Tamil
nadu)
