Dr. rajendra Prasad, first citizen of independent India.

Dr. Rajendra Prasad was the first President of independent India. He was the President of the Constituent Assembly that drafted the Constitution. He had also served as a Cabinet Minister briefly in the first Government of independent India. Dr. Rajendra Prasad was one of the foremost disciples of Gandhiji and he played a crucial role in Indian freedom struggle.
Dr. Rajendra Prasad, son of Mahadev Sahai, was born in Zeradei, Bihar on December 3, 1884. Being the youngest in a large joint family "Rajen" was greatly loved. He was strongly attached to his mother and elder brother Mahendra. In Zeradei's diverse population, people lived together in considerable harmony. Rajendra Prasad's earliest memories were of playing "kabaddi" with his Hindu and Muslim friends alike. In keeping with the old customs of his village and family, Rajen was married when he was barely 12 years old to Rajvanshi Devi.
Dr. Rajendra Prasad was a brilliant student. He stood first in the entrance examination to the University of Calcutta, and was awarded a monthly scholarship of Rs.30. He joined the famous Calcutta Presidency College in 1902.
Having made his choice, however, he set aside the intruding thoughts, and focused on his studies with renewed vigor. In 1915, Rajen passed the Masters in Law examination with honors, winning a gold medal. Subsequently, he completed his Doctorate in Law as well.
In July 1946, when the Constituent Assembly was established to frame the Constitution of India, Dr. Rajendra Prasad was elected its President. Two and a half years after independence, on January 26, 1950, the Constitution of independent India was ratified and Dr. Rajendra Prasad was elected the nation's first President. Dr. Prasad transformed the imperial splendor of Rashtrapati Bhavan into an elegant "Indian" home. Dr. Prasad visited many countries on missions of goodwill, as the new state sought to establish and nourish new relationships. He stressed the need for peace in a nuclear age.
In 1962, after 12 years as President, Dr. Prasad retired, and was subsequently awarded the Bharat Ratna, the nation's highest civilian award. With the many tumults of his vigorous and accomplished life, Dr. Prasad recorded his life and the decades before independence in many books, among the more noted of which are "Satyagraha at Champaran" (1922), "India Divided" (1946), his autobiography "Atmakatha" (1946), "Mahatma Gandhi and Bihar, Some Reminisences" (1949), and "Bapu ke Kadmon Mein" (1954).

Chanakya: the pioneer economist of the world.

Chanakya, a magnificent persona, was full of determination in accomplishing any objective. This expert economist and a statesman par excellence was also well versed in all `Shastras` or branches of knowledge. Chanakya was very full-grown master in the four methods - of persuasion, enticement, sowing dissension, and punishment or war. For anybody it was hard to makeup what was going on his mind. He was so tightlipped in his method and far-sighted that in any venture, his calculations never went wrong in order to reach his aim.

Chanakya, also known as Kautilya or Vishnugupta, was born in Pataliputra, Magadh (modern Bihar), and later moved to Taxila, in Gandhar province(now in Pakistan). He was a professor (acharya) of political science at the Takshashila University and later the Prime Minister of the Emperor Chandragupta Maurya. He is regarded as one of the earliest known political thinkers, economists and king-makers. He was the man to envision the first Indian empire by unification of the then numerous kingdoms in the Indian sub-continent and provide the impetus for fights against the Greek conqueror Alexander.
He compiled his political ideas into the 'Arthashastra', one of the world's earliest treatises on political thought and social order. His ideas remain popular to this day in India. In Jawaharlal Nehru's Discovery of India, Chanakya has been called the Indian Machiavelli. Three books are attributed to Chanakya: Arthashastra, Nitishastra and Chanakya Niti. Arthashastra (literally 'the Science of Material Gain' in Sanskrit) is arguably the first systematic book on economics. It discusses monetary and fiscal policies, welfare, international relations, and war strategies in details. Many of his nitis or policies have been compiled under the book title Chanakya Niti. Nitishastra is a treatise on the ideal way of life, and shows Chanakya's in depth study of the Indian way of life.

Aryabhatta : greatest contribution, given ZERO to the world.

Aryabhatta (476-550 A.D.) was born in Patliputra in Magadha, modern Patna in Bihar. Many are of the view that he was born in the south of India especially Kerala and lived in Magadha at the time of the Gupta rulers; time which is known as the golden age of India. There is no evidence that he was born outside Patliputra and traveled to Magadha, the centre of education and learning for his studies where he even set up a coaching centre. His first name “Arya” is hardly a south Indian name while “Bhatt” (or Bhatta) is a typical north Indian name even found today specially among the great “Bania” (or trader) community of Bihar.

Whatever this origin, it cannot be argued that he lived in Patliputra where he wrote his famous treatise the “Aryabhatta-siddhanta” but more famously the “Aryabhatiya”, the only work to have survived. It contains mathematical and astronomical theories that have been revealed to be quite accurate in modern mathematics. For instance he wrote that if 4 is added to 100 and then multiplied by 8 then added to 62,000 then divided by 20,000 the answer will be equal to the circumference of a circle of diameter twenty thousand. This calculates to 3.1416 close to the actual value Pi (3.14159). But his greatest contribution has to be zero. His other works include algebra, arithmetic, trigonometry, quadratic equations and the sine table.

He already knew that the earth spins on its axis, the earth moves round the sun and the moon rotates round the earth. He talks about the position of the planets in relation to its movement around the sun. He refers to the light of the planets and the moon as reflection from the sun. He goes as far as to explain the eclipse of the moon and the sun, day and night, the contours of the earth, the length of the year exactly as 365 days.

He even computed the circumference of the earth as 24835 miles which is close to modern day calculation of 24900 miles.

This remarkable Bihari was a genius and continues to baffle many mathematicians of today. His works was then later adopted by the Greeks and then the Arabs.
