Behold the man who shields his family from all suffering

Behold the man who shields his family from all suffering.
Has not his body become a willing vessel for affliction.
Without good men to hold it up, the family house will fall when misfortune descends.
— Tirukkural 103: 1029-1030

गणित
Ganita (Sanskrit: for mathematics; is derived from the root ‘gana’, which means to count or to enumerate.)
Mathematics in Ancient India
Mathematics in India has been cultivated in connection with
Astronomy. Like the other streams of knowledge, the early references of
mathematics, are also found in the vedic literature. The word
‘Rashividya’ is used for mathematics in Chhandogya Upanishad (7.1.2). Some hymns of Shuklayajureda reveal the knowledge of odd numbers and tables (18/24,25). The Brahmana texts like ; ‘ekaya svaha, dvabhyam svaha, tribhyah svaha’ reflect the vedic concept of arithmetical progressions. In Pingal Sutra there is a discourse on the calculation of squares and square roots.
The Indians; earlier than other nations; became familiar with the
system of place value of numerals. Undoubtedly the Europian system of
enumeration is of Indian origin. India is the birth place of several
mathematical concepts including zero, the decimal system, algebra,
algorithm, square root and cube root etc. The origin of calculus was in
India, even more than three centuries before Leibnitz and Newton
introduced their own theorems.
The concept of zero, i.e. shunya, which means ‘void’, a
figure to indicate the absence of a position of number is virtually
void. A round figure, symbol for zero, i.e. ‘0’ had emerged to represent
the philosophical concept of void.
Mathematics in India might have started more than five thousand years
ago. Since 1000 B.C. almost for a period of two thousand years, many a
number of mathematical works were produced in India. Since the 5th
centruay A.D., the method of graduated calculation had been introduced
in India. By that time, the geometric theories were known to the
Indians. We may see some displays of motifs on the walls of ancient
temples. Those motifs ideally reflect the patterns available in Indian
architecture, as we see the admixture of floral and wall pattern of
geometric method. These concepts, were collected and developed further
by the mathematicians like Aryabhata who flourished in the 5th Century
A.D. His work Aryabhatiyam is equally important for Mathematics and
Astronomy. The first part of the book explains the special system of
writing numerals that was introduced by Aryabhata alone. The Second part
gives a small anthology of mathematical teachings of Aryabhatta. He
deals in his work with evolution and revolution, area and volumes,
progressions and algebraic identities.
Brahmagupta’s work ‘Brahma-sphuta-siddhanta’ covers very briefly the
arithmetical operations, square and cube roots, interest, progressions,
geometry and simple algebraic identities.
Bhaskaracharya
the great astronomer, enjoys high reputation as a mathematician also.
His work Lilavati, in which a lovely maiden is addressed and problems
set to her, is a famous book on mathematics. The second book Bijaganita,
is the fullest and most systematic account of Indian algebra
Ganitasarasangraha of Mahaviracharya, Trishati of Shridhara, Bijaganita of Narayan are some prominent Sanskrit treatises on Indian Mathematics.

The ancient Hindus had given the world the idea of the smallest and
largest measuring units of Time. Astonishingly, the ancient Hindus used
the following units of time:

India gave the largest measurement of time as 8.64 billion years.
The Gregorian calendar on your desk simply adds on one day for every 4
years and is not in coherence with the movement of sun. But, Hindu
calendar is in coherence as the short fall is corrected in the month
itself by adding Adhikamasa as postulated by Maharshi Vishwamitra. Rig Veda
1.164.1, 2, 14 and 15 describe sun's motion, ritus and colours of
spectrum. Kalyana varma, Varahamihira, Jaimini, Vidyanatha Deekshita, Kalidasa,
Mantreshwara, Satyacharya, Venkatadri, Parashara, Ramadayalu and Garga
have immensely contributed for the development of Hindu astrology.
