Question 3.
Discuss ancient India’s progress in Medical Science and Surgery.
Answer:
Maharishi Charak, Maharishi Sushruta and Vaghatta were the pioneers of ancient India’s medical and herbal science and surgery. These people did extensive research and reached great heights. Maharishi Charak wrote a book ‘Charak Samhita’ in which he has mentioned about over 2000 medicinal herbs. Maharishi Sushruta wrote a book ‘Sushruta Samhita’ in which he has mentioned instruments used in surgery. The instruments were so sharp that they could split a single in two parts vertically. Vagbhatta wrote a book Vagbhatta Samhita’. Even today, all these three books serve as a very important reference for doctors. Vaghatta also wrote ‘Ashtang Hriday’ which is an excellent book for diagnosis.

(a) Knowledge about medicines: Ancient Hindu culture’s herbal science is enriched with huge collection of minerals and medicines that can be made from plants and animals. Our ancient literature on these sciences explains in detail all the complicated processes of making medicines, classifying them and their usage inproper way. They could recognize symptoms and diagnose the disease. Based on this they used to provide ayurvedic medicines.

(b) Surgery: The ancient Indian doctors were so skilled that to perform surgeries they could stop blood circulation using a special type of bowl-shaped bandage. They could skillfully operate abdomen, kidney, cataract, hernia, stone, piles, bladder, etc. They were expert enough to classify our bones. They could also join the broken or displaced bones and extract things pierced into the body easily and skilfully. They were skilled in plastic surgery as well joining nose and ears. Our ancient doctors had a deep interest in teaching . students the method of surgery. They used to demonstrate surgeries to students either on dead bodies or on wax statues. They also conducted risky operations during delivery. They were also expert gynaecologists and paediatricians and could treat related problems.

Veterinary Science: Veterinary science (Science of treating animals) also developed in ancient India. Ancient India had books written on diseases related to the horses (Ashwa) and elephants (Hasti). Among them ‘Hasti Ayurveda’, Shalihotra and ‘Ashwashastra’, are well-known.

Answer:
India has an extremely rich heritage of science and technology. India has made enumerable contribution in the fields of metallurgy. Chemistry, mathematics, medicines and surgery, astrology and astronomy, Vastushastra, etc. The statue of Nataraja made during Chola period is a finest example of metallurgy in the world. Acharya Nagarjuna has made us pround with his immense and rich work in chemistry. ‘Rasa- ratnakar and ‘Arogya-manj ari ’ are two of his great books describing about various chemicals found in chemistry.

Due to his knowledge and legacy that Nalanda University had setup school of chemistry in the university campus for research and studies in ancient time. Several structures such as the copper statue of Buddha of Sultanganj, statue of Buddha at Nalanda, Vijay Stambha, are a few of the best examples of our excellence in chemistry.

Maharshi Charak, Maharshi Sushruta and Vagbhatta were the pioneers of ancient India’s medical and herbal science and surgery. These people did extensive research and reached great heights. Their books ‘Charak Samhita’, ‘Sushruta Samhita’ and Vagbhatta Samhita’ are still in use as reference by modem doctors. The ancient Indian doctors were so skilled that to perform surgeries they could stop blood circulation using a special type of bowl-shaped bandage.

They could skillfully operate abdomen, kidney, cataract, hernia, stone, piles, bladder, etc. Veterinary science also developed quite well in ancient India. India has made a notable contribution in the field of mathematics. India’s some of the finest gifts to the world are discovery of ‘0’ (zero), decimal system, algebra, theorem of Baudhayana, Geometry and Arithmetic. Aryabhatta discovered ‘zero’ (0), gave an approximate value of % (pi) as ‘3.14 or say 22/7’. Brahmagupta gave the knowledge about the types of equations in mathematics. Baudhayana gave another version of Pythagoras theorem. Many works related to astronomy have been written in India.

Ancient universities of India did systematic and deep study of astrology. Aryabhatta made a remarkable contribution in the field of astronomy. As a result, when India launched its first satellite, it named it ‘Aryabhatta’. He declared that the earth rotates on its own axis. Brahmagupta mentioned about the laws of gravitation in his book ‘Brahmasiddhant’. One of the greatest astrologers and astronomer Varahmihir divided astrology into three sections namely Tanta’, ‘Hor’ and ‘Samhita’. Ancient India had also made tremendous contribution in vastushastra. Brahma, Narad, Brahaspati, Bhrugu, Vashishtha and Vishwakarma have made unique contributions in the field of Vastushastra. Today, the western countries have also adopted Vastushatra in various aspects. Thus, India had a rich ancient heritage in science and technology which made India world famous.

II. Answer the following questions pointwise.

Question 1.
Write about the progress made by ancient India in mathematics.
Answer:
India has made a notable contribution in the field of mathematics. India’s some of the finest gifts to the world are discovery of ‘0’ (zero), decimal system, algebra, theorem of Baudhayana, Geometry and Arithmetic. Aryabhatta discovered ‘zero’ (0) whereas the knowledge of writing zero after figures was discovered by the sage named ‘Grutsamad’. The ancient Indian mathematicians gave the names of the numbers formed by placing up to 53 zeros after 1 (one). Archaeologists found out that the measuring and weighing instruments of Harappa’ and ‘Mohenjodaro’ used decimal system.

“Medhatithi’, the great mathematician, gave the concept of this decimal system. Bhaskaracharya wrote books ‘Lilawati Ganit’ and “By Ganit’ in 1150 AD. He discovered signs of addition (+) and subtraction (-). Brahmagupta gave the knowledge about the types of equations in Mathematics. Baudhayana gave another version of Pythagoras theorem. Around 800 BC., ‘Aapstambha’ wrote a book called ‘Shulba Sutra’. In this book, he gave the method to accurately calculate dimensions for constructing altars needed for sacrifice. These sacrificial pits were also called ‘yagyavedis’ and were used for Vedic yagyas. His book also contains analysis of several principles.

Aryabhatta is known as the ‘father of Mathematics’. He wrote a book called ‘Hryabhattiyam’. In this book, he gave an approximate value of x(Pi) as ‘3.14 or say 22/7’, He also suggested that rc(pi) is the consant which works as a multiplier in the equation of circumference and diameter of circle. He also gave information about Ashtang method of multiplication, addition, subtraction, square-root, cube-root, etc.

Aryabhatta also wrote books like ‘Dash Gitika’ and ‘Aryabhattiyam’. In his book ‘Aryasiddhanta’, he had described the main principles of astronomy. He also found the solution of various fundamentals of arithmetic and geometry. Apart from this, many scholars have contributed various aspects of mathematics in their works and books.
