Brahmagupta Biography:--
Brahmagupta was a famous Indian mathematician and astronomer who made invaluable contributions to the field of science and mathematics through his important works in the 7th century. His works not only influenced Indian science but also inspired Islamic and European scholars. His works, especially "Brahmasphutasiddhanta" and "Khandakhaddaka", establish fundamental principles in the field of mathematics and astronomy. In this article we will discuss in detail about the life of Brahmagupta, his works, and his contributions.
Early life and background:--
Brahmagupta was born in 598 AD. His birthplace is believed to be in Bhinmal (then Bhillammal) in present-day Rajasthan. Bhinmal was an important center of the Gurjar Empire at that time and there was a lot of activity in the field of education and science here. Brahmagupta's father Vishnugupta was also a scholar, who played an important role in his early education.
Brahmagupta, the great mathematician of the Gupta period who first explained zero, was born in Bhinmal in western India, which is today in Bhinmal district Jalore, Rajasthan. At that time it was the capital of Gujarat. His father's name was Vishnugupta and grandfather's name was Jishnugupta. His workplace was Ujjain city, which was a major center of education and knowledge at that time.
Before Brahmagupta, there were many theory texts in India and one of them was 'Brahma Siddhant'. But many of its things had become outdated, which did not match the new research of that time. Brahmagupta gave a new form to this theory and composed a great text, titled 'Brahmasphuta Siddhant'.
The word 'Sphuta' means-spread or modified. His second text was 'Khand Khadyak'. A glimpse of Brahmagupta's talent, scholarship and research is seen in his 'Brahmasphuta Siddhant', in which various branches of mathematics and astrology have been discussed in detail.
It has 25 chapters and 1,008 verses. Its twelfth chapter i.e. 'Ganitadhyaya' contains information on topics related to arithmetic and mensuration and the eighteenth chapter i.e. 'Kukkutadhyaya' discusses algebra. In one verse of this book, he has also given a very brief introduction of himself, according to which he wrote this book at the age of 30 in the reign of King Vyaghramukh of the Chaap dynasty in the Shaka Samvat 550. Brahmagupta's contribution was invaluable. He first used algebra, but he named it 'Kukkuta Ganit'.
Prithudak Swami (860 AD), the commentator of his 'Brahmasphuta Siddhanta', first used the word 'algebra'.
In the time of Aryabhatta itself, the system of expressing all numbers with ten symbols including zero, which is currently called the decimal system, had been developed; But Brahmagupta was the first to explain it and said, “Adding or subtracting zero to a number does not change that number. Multiplying or dividing a number by zero makes it zero.
He showed the following properties of zero – x-o = x -x-o = -x o-o = o x x o = o o x o = o o ÷ o = o Out of these o ÷ o o is not correct. He called x ÷ o as ‘Tatched’. ‘Tatched’ means – Kha-ched i.e. infinity. Today the credit for many of Brahmagupta’s discoveries is given to Western mathematicians.
He developed formulas to find the area of a circular quadrilateral. He also did many types of research in the field of astronomy and gave new knowledge to the world. He believed that the earth is stable and in ‘Brahmasphuta Siddhanta’ he told the duration of a year as 365 days, 6 hours, 5 minutes and 19 seconds. He prepared his second work 'Khand Khadyak' at the age of 67, which has eight chapters. In this, he has explained in detail the method of making a Panchang.
In this also, he calculated the duration of a year and told it to be 365 days, 6 hours, 12 minutes and 36 seconds. Such a subtle difference shows how anxious he was to move towards accuracy. But it seems, Brahmagupta was not that courageous. He not only ignored the courageous new ideas of Aryabhatta but also opposed them in many matters. It is surprising that he considered solar eclipse and lunar eclipse as the effect of Rahu-Ketu. But he was a great observer. In his 'Brahmasphuta Siddhanta', he also described many astrological instruments in Yantraadhyaya. It is believed that he must have invented the Turiya Yantra.
Indian mathematicians and Arabic mathematicians of later times mentioned him respectfully in their works. When Kukkutadhyaya was translated into English in 1817, European scholars came to know that modern algebra is actually based on Indian algebra. It is believed that Brahmagupta also wrote a book called 'Dhyana Guhopadesha'; but it is not available now.
According to estimates, he died in 680 AD. Both his texts were translated into Arabic, which strengthened the foundation of Arabic mathematics.
Education of Brahmagupta:--
Brahmagupta received his education in Bhinmal itself and later he went to study at the famous astronomical center of Ujjain. Ujjain was the main center of astronomy and mathematics at that time, where great scholars like Aryabhata also studied.
Major works of Brahmagupta:--
Brahmagupta composed two major texts in his lifetime, which reflect his knowledge and dedication to science. These texts are:
Brahmasphutasiddhanta (Brahmasphut Siddhanta):--
This text was written in 628 AD and is considered to be the most important work of Brahmagupta. This text is divided into 25 chapters and discusses various aspects of mathematics and astronomy. The principle of zero, the use of negative numbers, and the basic principles of algebra are explained in detail in this text.
Khandakhadyaka:--
This text was written in 665 AD and focuses on astronomical calculations. This text is famous for its simple and accurate calculations and is considered an important contribution in the field of astronomy.
Contribution to Mathematics
Brahmagupta established many fundamental principles in the field of mathematics, which are still relevant today. His major contributions are as follows:
Theory of Zero:--
Brahmagupta defined zero as a number and explained its properties. He explained that adding or subtracting zero to a number does not change that number. Apart from this, he also clarified the rules of multiplication and division by zero.
Negative Numbers:--
Brahmagupta made significant contributions in using negative numbers and explaining their properties. He explained how to add and subtract negative numbers.
Algebra:--
Brahmagupta gave formulas for solving quadratic equations. He developed various methods for solving equations, which are still useful for mathematics students today.
Geometry:--
Brahmagupta gave a formula for calculating the area of a cyclic quadrilateral, which is called "Brahmagupta's formula". This formula is still important in the field of geometry.
Contribution in Astronomy:--
Brahmagupta also made significant contributions in the field of astronomy. He developed various theories for the motion of planets, calculating eclipses, and predicting celestial events. Following are some of his major contributions:
Motion of planets:--
Brahmagupta developed mathematical models to explain the motion of planets. He explained how the motion of planets can be measured and how their position can be calculated.
Calculation of eclipses:--
Brahmagupta developed accurate methods for calculating solar and lunar eclipses. He explained when and how eclipses occur and how their duration can be measured.
Astronomical instruments:--
Brahmagupta developed various instruments for astronomical calculations. Using these instruments astronomers could study celestial phenomena.
Legacy of Brahmagupta:--
Brahmagupta's works influenced not only Indian science but also inspired Islamic and European scholars. His texts were translated into Arabic and Persian and were studied in medieval Europe. The theories he gave laid the foundation of modern mathematics and astronomy.
Brahmagupta's legacy is still inspiring for students of mathematics and science. His works proved how much advancement was made in the field of science and mathematics in ancient India.
What are negative numbers?
Negative numbers are numbers that are less than zero. They are represented with a minus sign (-). For example, -1, -2, -3, etc. are negative numbers. These numbers are useful in real life to represent debt, decrease in temperature, or decrease in any quantity.
History of Negative Numbers:--
Negative numbers have been used since ancient times, but the credit for defining them mathematically and explaining their properties goes to Brahmagupta. Brahmagupta wrote in detail about negative numbers in his book "Brahmasphutasiddhanta" in the 7th century. He clarified the rules of addition, subtraction, multiplication and division of negative numbers.
Properties of Negative Numbers:--
Brahmagupta defined the following properties of negative numbers:
Addition:--
The sum of two negative numbers is a negative number.
Example: (-3) + (-2) = -5
The sum of a positive and a negative number is equal to their difference.
Example: 5 + (-3) = 2
Subtraction:--
Subtracting a negative number from a positive number gives the result.
Example: 5 - (-3) = 8
Subtracting a positive number from a negative number gives the result even more negative.
Example: (-5) - 3 = -8
Multiplication:--
The product of two negative numbers is a positive number.
Example: (-3) × (-2) = 6
The product of a positive and a negative number is a negative number.
Example: 3 × (-2) = -6
Division:--
The quotient of two negative numbers is a positive number.
Example: (-6) ÷ (-2) = 3
The quotient of a positive and a negative number is a negative number.
Example: 6 ÷ (-2) = -3
Use of negative numbers:--
Negative numbers are used in various fields, such as:
Finance:--
To show debt or loss.
Example: If someone's bank balance is -500 rupees, it means that he has borrowed 500 rupees.
Temperature:--
To show the decrease in temperature.
Example: -10°C means that the temperature is 10 degrees below zero.
Physics:--
To show the direction of motion or force.
Example: If the velocity of an object is -5 m/s, it means that the object is moving in the opposite direction.
Mathematics:--
In solving equations and inequalities.
