The story behind the invention of the Stethoscope


Rene Laennec’s 235th Birthday

René Laennec - How he invented the Stethoscope !


In 1816, shyness led Laennec to invent the stethoscope. He was examining a young woman complaining of heart problems. At that time, doctors generally listened to patients' heartbeats by resting an ear against the patient's chest, but the conservative Laennec thought this improper under the circumstances, especially as she was overweight. He rolled a piece of paper into a tube and pressed it to her chest, allowing him to hear the sounds of her heart. Some believe he was inspired by the flute, which he used to play.

Why & How we should study AI & Machine Learning (6 Easy Steps)

AI & ML are fundamental new technologies that can create immense value to humankind. It is very important for us to learn AI & ML and apply this knowledge in our work.  If you are somebody like me without prior exposure to computers, you may wonder where to begin the journey – I did some homework and found an easy step-by-step using online resources . It takes only 6 easy steps to gain mastery in AI & ML. I will start with sharing with you the talk that Risto Siilasmaa (Chairman, Nokia) gave in Nov, 2017 – “Why you should study AI and Machine Learning and how I did it”. Step # 1 - Risto Siilasmaa started his journey into AI & ML by asking, “Where could I find good material explaining how machine learning works in terms that would speak to an engineer who loves to understand how things work?” Step # 2 - “ Why not study machine learning myself and then explain what I learned to others who are struggling with the same questions. Perhaps I could mo...

Archimedes' Bathtub, Newton's Apple and Einstein's Chair

When do Great Ideas come ? .... after Incubation  Archimedes had his bath, Galileo had his leaning tower,  Newton had his apple, and Einstein had his chair. All these Inventors were (a) intensely focused on solving specific physics problems (b) they had each looked at a variety of promising ideas, but reached an impasse after some stage (c) they smartly decided to move away from the scene - took a break (d) after some time, a fresh idea popped into their Mind (e) they recognized the potential of the idea and held on to it (f) they diligently worked on it  and finally developed a real breakthrough concept. Many Inventors have shared the vale of incubating their idea and described specific instances where the incubation phase is followed by a sudden enlightenment. We have heard the stories of Archimedes, Galileo and Newton too often - so let us focus on Einstein's story. You might have heard of Einstein's Violin but not about his chair - the chair that gave...

Future Mobility Technology Trends - Insights from Paul Masceranas

Future Mobility Technology Trends a fire-side chat session with Mr Paul Masceranas, President SAE International at Mahindra Research Valley. When the SAE International President Mr Paul Masceranas visited Mahindra Research Valley on 24 June 2019, a small group of Inventors and Innovators had a fire-side chat session with Paul. The topics discussed covered a wide spectrum – from new-gen technologies like electric, autonomous, connected vehicles to the future of current technologies internal combustion engine (ICE) technologies, Diesel etc. Since Paul’s views on these topics could be of interest to a larger community of engineers, we thought of sharing a summary of the discussion here. Dr Shankar Venugopal (Vice President, Mahindra & Mahindra), Mr Paul Masceranas (President, SAE International) and Mr Murli Iyer (Executive Advisor – Global Affairs, SAE International) at the Mahindra Research Valley, Chennai (24 June 2019) The session started with the modera...
