Studying the Stomach

In his awesome book, The Body: A Guide for Occupants, Bill Bryson says that for a very long time, almost everything we knew of the stomach was due to an unfortunate accident in 1822. A rifle being examined went off accidentally tearing a hole in the lower chest of a bystander, Alexis St Martin. While the man survived, the wound never healed giving him the “most famous stomach in medical history”.

 

His doctor, William Beaumont, realized the inch-wide hole gave him an “unusual window” into his patient’s insides and a “direct access to his stomach”. Back then, nobody knew what happened to food once it went down the throat. So Beaumont would suspend different foods on lengths of silken thread into St Martin’s stomach, leave them for different time periods, then “pulling them out to see what had happened”.

 

At times, in the interest of science (of course):

“(Beaumont) tasted the contents (of the extracted food) to judge their tartness and acidity, and by doing so deduced that the principle digestive agent of the stomach is hydrochloric acid.”

 

It reminded me of Hobbes’ line in the last panel of this strip:

Student of the Year

Image
As a toddler, my daughter loved Alia Bhatt’s songs, esp. the ones from Student of the Year . (That movie did have many good songs and well-choreographed dances). Fast forward to present day, when she is 12 yo. She rarely watches Hindi movies now, but one of the few ones she likes of late, Raja aur Rani ki Prem Kahani has, yes, Alia Bhatt.   If I had any hopes that there was anything to be read in the name of her toddler-time favorite ( Student of the Year ), they have been dashed. Our conversations come exam time are perfectly captured by this photo and its caption: In fact, the pic below captures how she and I look at her answer sheets – me intently, she with an expression of “It’s over, so why are you even looking at it?”   Of late, we pull her leg and tell her that she isn’t showing any signs of academic prowess, she’d better find a rich guy to marry. Some time later, she showed us this meme on the Internet: “Me No Study, Me No Care Me Go Marry Millionaire If He Die

Why we Deceive Ourselves

In their book, The Elephant in the Brain , the authors describe this weird aspect of deception that we practice: deceiving ourselves! That is so weird: “If our minds contain maps of our worlds, what good comes from having an inaccurate version of these maps?” The Sigmund Freud school of thought treats self-deception as a defense mechanism, “a way for the ego to protect itself”. The mind seeks to protect itself from anxiety and other negative emotions. Many object to this reasoning: since accurate information is so critical to our survival, surely distorting information would be dangerous. Wouldn’t the goal of protecting our self-esteem have been better achieved by making the brain’s self-esteem mechanism stronger instead? The new school of thought explains self-deception as “primarily outward-facing, manipulative, and ultimately self-serving”. This is based on Thomas Schelling’s work on game theory: “In a variety of scenarios, limiting or sabotaging yourself is the winn

Handling of the Satyam Scam

The Satyam scam. How does that fit into Montek Singh Ahluwalia’s book on reforms in India, Backstage ? The reason is that, as both NASSCOM and the government of India felt: “(Satyam’s) collapse would create a great deal of disruption for clients worldwide and seriously damage India’s reputation as a reliable source of software services.”   Therefore, the government decided to work with the private sector to “organize a quick takeover by a reputable new buyer, who would quickly restart the company”. But that could not be done overnight. In the meantime, the new board would have to reach out to Satyam’s clients and “reassure them that the company would survive”.   For the new board to have credibility when it made that statement, it had to be staffed with people who understood the private sector, the IT sector in particular, and commanded respect and trust. Deepak Parikh from HDFC was made chairman, and other members of the board included a former NASSCOM chairman, CII member,
