22 December - Guru Gobind Singh born in 1666

 

 

Guru Gobind Singh born Gobind Das or Gobind Rai (22 December 1666 – 7 October 1708) was the tenth and last human Sikh Guru.He was also a warrior, poet, and philosopher. At the age of nine—after his father (Guru Tegh Bahadur) was executed by Emperor Aurangzeb—he was formally installed as the leader of the Sikhs.His four biological sons died during his lifetime – two in battle and two executed by the Mughal governor Wazir Khan.

Among his notable contributions to Sikhism are founding the Sikh warrior community called Khalsa in 1699 and introducing the Five Ks, the five articles of faith that Khalsa Sikhs wear at all times. Guru Gobind Singh is credited with the Dasam Granth whose hymns are a sacred part of Sikh prayers and Khalsa rituals.He is also credited as the one who finalized and enshrined the Guru Granth Sahib as Sikhism's primary scripture and eternal Guru

22 December - Srinivasa Ramanujan birth anniversary

 

Srinivasa Ramanujan was an extraordinary Indian mathematician who made groundbreaking contributions to the field of mathematics. Here's a short write-up about him, including his birth and death dates:

• Birth Date: Srinivasa Ramanujan was born on December 22, 1887, in Erode, Tamil Nadu, India.

• Early Life: Ramanujan displayed an early aptitude for mathematics and developed a passion for the subject during his childhood. Lacking formal training, he relied on self-study and exploration of mathematical texts.

• Mathematical Genius: Ramanujan's mathematical insights and discoveries were truly exceptional. His work primarily focused on areas such as number theory, infinite series, and mathematical analysis. He had an innate ability to intuitively grasp complex mathematical concepts and formulate elegant theorems.

• Collaboration with G.H. Hardy: Ramanujan's talent was recognized by British mathematician G.H. Hardy, who invited him to the University of Cambridge in England. Their collaboration resulted in groundbreaking research and theorems. Ramanujan's work on partition functions, mock theta functions, and modular forms, among others, was particularly noteworthy.

• Contributions: Ramanujan's contributions to mathematics continue to be of immense importance. His formulas and theorems have applications in various areas of mathematics, including number theory, analysis, and algebra. Mathematicians around the world still study and build upon his work.

• Death Date: Tragically, Srinivasa Ramanujan's life was cut short. He passed away on April 26, 1920, in Kumbakonam, Tamil Nadu, India, at the young age of 32.

• Legacy: Ramanujan's legacy is celebrated worldwide, and he is considered one of the greatest mathematicians in history. His story is a testament to the power of human curiosity, talent, and perseverance in the pursuit of knowledge.

Srinivasa Ramanujan's life and work continue to inspire mathematicians and students, and his contributions to the field of mathematics are remembered and revered to this day.

 

22 December - National Mathematics Day India

 

National Mathematics Day is celebrated in India on December 22nd each year to honor the birth anniversary of the renowned Indian mathematician, Srinivasa Ramanujan. This day was established to recognize his exceptional contributions to the field of mathematics and to promote mathematics as a subject of importance and interest.

Key points about National Mathematics Day:

1. Srinivasa Ramanujan: Srinivasa Ramanujan was born on December 22, 1887, in Erode, Tamil Nadu, India. He was a self-taught mathematical genius known for his extraordinary mathematical insights and discoveries. His work has had a profound and lasting impact on various areas of mathematics, including number theory and mathematical analysis.

2. Recognition of Talent: Ramanujan's mathematical talent was recognized by British mathematician G.H. Hardy, and he traveled to England to work with Hardy at the University of Cambridge. His collaboration with Hardy led to significant mathematical breakthroughs.

3. Contributions: Ramanujan made substantial contributions to areas such as infinite series, modular forms, and elliptic functions. Many of his formulas and theorems continue to be studied and applied in mathematics and related fields.

4. Celebrations: On National Mathematics Day in India, various educational institutions, mathematicians, and math enthusiasts organize events, seminars, workshops, and mathematical competitions to celebrate the beauty and importance of mathematics. The day also aims to inspire students to pursue mathematical studies and research.

5. National Mathematics Day Resolution: In 2012, the Indian government declared December 22nd as National Mathematics Day to recognize Ramanujan's contributions and to promote the development of mathematics in India.

National Mathematics Day serves as an occasion to remember and celebrate the achievements of Srinivasa Ramanujan and to promote the study and appreciation of mathematics among the youth of India.

22 December - Samrat Vikramaditya commemorative stamp issued in 2016

 

Vikramaditya was an emperor of ancient India, considered the legendary king. He is well known for his generosity, courage, and patronage of scholars. Samrat Vikramaditya began his rule after defeating Shakas in the VikramSamvat era in 57 BCE.

Samrat Vikramaditya is a feature in several traditional stories including BaitalPachisi and SinghasanBattisi. Some scholars claim that King Vikramaditya was probably based on the Gupta king Chandragupta II. Based on coins and the Supia pillar inscription, it is believed that Chandragupta II adopted the title Vikramaditya.

The government of India issued this commemorative stamp of SamratVikramaditya, on 22nd December 2016 to commemorate him.
