As a student, Chemistry was not my favourite subject – I scored 98% in my 12th Standard exam (school leaving exam) but that was thanks to a great teacher I had, and not due to me. Even then, reading the periodic table I was amazed by its elegance and rhythm. It just felt like a divine truth and I had not thought of the history behind its invention. Last week, The Economist had this wonderful article (just four pages) tracing the people and the journey behind Periodic Table – from “French” Antoine-Laurent de Lavoisier in 1789, “French” Louis-Joseph Proust in…

Today, VarahaMihira Science Forum had organised a talk at Tamil Virtual Academy, Chennai titled “A brief history of gravity”, delivered by Dr Satish Kumar Saravanan, Riemann Fellow of Riemann Center for Geometry and Physics. Dr Satish started with the well-known (fiction?) story of a falling apple into the lap of Newton, who went on to discover the force of Gravity. Followed this was the fictitious(?) story of Galileo dropping two balls of varying mass and volume from the top of the leaning tower of Pisa. Then was a BBC video by Brian Cox on how in a vacuum if we…

There are few living scientists today who are known outside their field of work,  well recognized throughout the world and are an inspiration to students to take to science. That credit goes to Dr.Stephen Hawking, who has done phenomenal contribution to general theory of relativity, his work on Hawking radiation, our understanding on quantum mechanics and cosmology. The little bit of interest I developed in Physics, Cosmology was after I read Dr.Hawkings book “The Brief History of Time” in late 80s, around the time I was in Junior college. Dr.Hawking’s have achieved all this in defiance to his crippling illness…

Hanuman was written and directed by V. Sreevathson, who also has played the main character of ISRO Chairman Dr.Lakshman. The reusable Rocket (Hanuman) was  build by sheer determination…

Last week “The Economist” in its Intelligent life feature carried an interesting article titled “Some like it very hot”. It talks about extremophiles. Wikipedia defines them as “organism that thrives in physically or geochemically extreme conditions that are detrimental to most life on Earth”. This biological category was discovered only 40 years back. We seem to think, as the Human race we know everything to know about Planet Earth’s life forms and what’s left is to explore life on other planets like Mars. But the truth is that our last 200 years of scientific progress covers the surface land we…
