Let's join Bhavisha and Dhruv with their time machine in the time of the Guptas. You are getting an opportunity to meet Āryabhaṭa and Varāhamihira—what would you ask them? Divide the class into two groups and create a series of questions for an interview with them.
Sample interview questions for Āryabhaṭa:
-
How did you determine that the Earth spins on its axis when most people believed the Sun moved around the Earth?
-
What methods did you use to calculate the length of the year so accurately?
-
How do you explain solar and lunar eclipses to people who fear them as supernatural events?
-
What inspired you to write the Āryabhaṭiya, and who were your teachers?
-
How can your mathematical techniques help students today?
Sample interview questions for Varāhamihira:
-
How did you combine astronomy, astrology, weather forecasting, and architecture in one work?
-
What is the connection between celestial observations and earthly events?
-
How did Ujjayinī's tradition of learning influence your work?
-
What practical applications does the Bṛhat Samhitā have for farmers and city planners?
-
How do you blend traditional knowledge with logical reasoning?
Explanation
The chapter provides detailed information about both scholars on Pages 14-15. Āryabhaṭa lived in Kusumapura around 500 CE, authored Āryabhaṭiya, proposed Earth's rotation, calculated the year's length, and explained eclipses. Varāhamihira lived in Ujjayinī and wrote Bṛhat Samhitā covering astronomy, astrology, weather, architecture, and farming. Students should formulate questions based on these contributions.
