Meghnad Saha: Decoding the Stars, One Equation at a Time
Have you ever gazed at the night sky and wondered what makes stars shine so brightly? The answer, it turns out, lies in the incredible work of Indian astrophysicist Meghnad Saha. Today, we delve into the life and legacy of this scientific giant who cracked the code of stellar composition. Born in 1893 in Dhaka, then part of British India, Saha displayed a keen interest in science from a young age. He excelled in mathematics and physics, eventually earning his doctorate from the University of Calcutta. But it was his groundbreaking research on stellar atmospheres that truly catapulted him to fame.
