Chai and Why?

Negating the genuine
Exaggerated claims of the past: Undermining the achievements of Indian science

Mayank Vahia

Sunday, 2nd September, 2018
11:00 am
Prithvi Theatre

In recent times one hears several exaggerated claims about scientific and technological achievements in ancient India. In this session we will discuss some outstanding examples of ancient Indian science and then focus on why many of the recent claims are not tenable. We will show that many of the said achievements could not have been possible, based on their own basic knowledge as discussed in the description of their lifestyle.
About the speaker: Prof. Mayank Vahia, Dept. of Astronomy and Astrophysics, TIFR has worked in diverse areas from high-energy astrophysics to archaeo-astronomy.

*** PLEASE BE AT THE VENUE BY 10:50 AM to ensure a seat. Prithvi Theatre has a strict no-late-entries policy ***

D.G. Ruparel College, Matunga (W), Mumbai
Room 7-Arts

Sitting at the centre of almost every galaxy is a supermassive black hole, somewhere between a million and a billion times the mass of our Sun. In our galaxy, this black hole is thankfully relatively calm, but in others, it is feeding on vast quantities of matter and releasing enourmous amounts of energy. These so-called "active galactic nuclei" are the brightest objects we see in the universe. What exactly is going on at the centres of galaxies? How are these exotic objects powered? What can we learn from studying them? Come to Chai and Why? to find out more...

About the speaker: Lankeswar Dey works on Active Galactic Nuclei (AGN), supermassive binary black hole systems and Pulsar Timing Array (PTA) in the Dept of Astronomy and Astrophysics at TIFR.

ENTRY FREE! No pre-registration required. Please be on time. We start punctually.

Seven Small Bridges, One Giant Graph Problem

Harita Rawal
TIFR

In this session, we will try to solve some childhood puzzle like complete a figure without lifting a pen or the famous Koenigsberg bridge problem. We will try to find creative ways to solve these puzzles. The process of solving these problems will also help us understand mathematically why some puzzles can't be solved.
