Pratidhvani - Humanizing Science

Science EN ↓ 126 episodes

Namaste, Hola, & Welcome from G.V. Pavan Kumar. Pratidhvani (ಪ್ರತಿಧ್ವನಿ/प्रतिध्वनि) means reflection or resonance (of sound). Here, the aim is to resonate with knowledge & humanize science. The podcast conversation has two themes:1) Intellectual journey of scientists, philosophers and historians of science;2) History & Philosophy of Physical Sciences & Technology I am a Professor of Physics at the Indian Institute of Science Education and Research, Pune, India. I run this podcast in my personal capacity. Main feed of the podcast: https://historyofscience.in/
