Book Review: Half - Lion: How P.V Narasimha Rao Transformed India by Vinay Sitapati


In one of the episodes of the Seen and the Unseen podcast I have written about earlier, this author was interviewed few months back about this book. Interview was very good. My longtime friend & colleague Sanjay Padubidri and I were discussing the episode and thought we should read the book. Lo and behold, when I saw him last March, Sanjay gave me the book as part of our regular book exchange program. So, read it, liked it.

P.V.Narasimha Rao was the Prime Minister of India from 1991 to 1996 (5 years that form one full term). This book is about his time and administration. TBH, I am not much into biographies. I generally think more than someone's personal story, I should focus on and learn from their unvarnished contributions. Naturally there are exceptions, and those who like biographies may have different perspectives that could be justified. Though this book is mostly biographical, spotlight was on this gentleman's unusual administrative style, and so it was engaging, informative. 

For those who may not be familiar with Hindu mythologies, there is a story of a demon king (named Hiranyakashipu) who had a pious son (named Prahalatha). The king had boons from the Gods that said he can be killed neither by a human being nor an animal, neither in the daytime nor at night, neither inside the house nor outside the house. Thinking that he has conquered death, he becomes a tyrant. Finally answering his son's prayers, God appears in one Avatar called Narasimha that is half human (Nara) and half lion (Simha) and kills the demon king on the door sill, during the evening hour, meeting all the conditions stipulated in the boon! This Indian PM who had that name, ruled successfully for five years, by being a lion sometime and human being sometime and even a fox or a mouse as time/conditions required, as he headed a minority government throughout his term, that could have fallen down any day (as it was common in the multi-party democracy of India). While his hold on power was tenuous, he managed to herald the kind of economic reforms never seen in the Indian history, that has now lifted hundreds of millions of people out of poverty and has set India on a course to becoming an economic superpower in the coming years. While many other leaders around the world might have brought in economic reforms that transformed their country, all of them had either unassailable democratic majority mandate or were some form of dictators that didn't have to worry about their government falling apart. Doing great/difficult things while you don't have to worry about the stability of your Govt is comparatively easier. Doing it while you don't have such stability is completely different, visionary, courageous endeavor. P.V.N.R managed to pull this off and so deserves a lot of credit that he didn't get for a long time. Thankfully he is starting to be recognized for his contributions now, due to works like this one.

First chapter of the book starts with his death in 2004. Though he was Ex-PM, he wasn't accorded the kind of state funeral/respect in the country's capital New Delhi since his own party leaders (particularly Sonia Gandhi) didn't want him to get a lot of fame/name. He was cremated in his native state of Andra Pradesh, where he served as Chief Minister decades earlier. The book then goes back to his earlier days as a party worker. He was elected as CM (equivalent to State Governor in the US), mainly because he didn't have a lot of personal fandom/base and so the party elites thought he will be easy to manage. They did knock him off power before he completed his CM term and ostracized him for a while. Instead of forming a competing party or accusing the leadership of not supporting him, he remained loyal, focused more on literature, writing, etc. for years. 

Though he was born in 1921, he traveled outside India for the first time only in 1976 to visit his daughter living in the USA. That trip apparently changed some of his socialistic views. After the scion of the Nehru/Gandhi dynasty Rajiv Gandhi was assassinated in 1991, when the party came to power, he was made PM, again primarily because he was considered weak with no support base of his own. But decades of his experience in state and the central level had given him enough insights into the Indian politics. Leveraging these skills, he immediately took up major economic reforms with Dr. Manmohan Singh (who became PM more than a decade later himself) serving as his finance minister. Often the reforms were painted as initiatives forced on India by IMF since India needed loans, its foreign exchange reserves were so low, etc. But the ideas for reforms were there for several years without anyone at the helm willing to take them up. PVN made good use of the opportunity, blamed the IMF rolling them out and stuck to it, even after the finance crisis was over. There are lot of interesting stories, tactics related to his administration that are quite interesting. To give another example, India becoming nuclear power is mostly thanks to him. In many of these cases, he tactfully avoided taking credit for them or intentionally gave credit to Nehru, Rajiv Gandhi, etc. so that his party base will continue to support him, while most of the actual changes he brought in were totally opposite to the party's old policies! 

It was heartening to note that the subsequent BJP PM Vajpayee, who was heading the country when India became a nuclear power, gave all the credit to PVNR saying, all the prep work was already complete during the previous administration, while he only exploded the device. PVNR spoke 10 different languages, learned to do computer programming on his own, knew Unix, wrote novels, could use very clever tactics suitable to Indian politics to get things done were all very well chronicled. The author being a an academic, certainly didn't write an all-appreciation ode, but points out his negative qualities, talks about marital infidelity, areas where he failed also well. But after about chapter 10, the initial chronological writing comes to an end and so it feels like the book is starting all over again to go back and discuss specific areas (e.g. nuclear detonation prep, Babri Masjid debacle) that drags the pace down. Still, it is not too boring, and the prose is quite accessible. Though I wasn't living in India during his PM years, along with the rest of the Indian diaspora and many economic scholars around the world, I did follow his reforms closely with a lot of enthusiasm and so was quite familiar with the period and the changes he brought in that were such a breath of fresh air. Current Indian PM has a cult like following in India and these days politicians all around the world have learned to leverage social media to get the limelight on them. But PVNR's admin style was quite the opposite and so it is good to see him getting the credit he deserves through works like this one. 

In case you don't think you can read this whole book, you can consider listening to this podcast episode that covers most of the details discussed in the book very well.

Book Review: The Idea Factory by Jon Gertner

When our family friend Sriram Tyagarajan mentioned this book titled "The Idea Factory Bell Labs and the Great Age of American Innovation" by Jon Gertner, it immediately piqued by curiosity since my first business card after my grad school days looked like the first picture attached! Of course, Sriram (and many other friends on my mailing list) are also Bell Labs alumni, that immediately amplifies the resonance for many of us. I should confess that the few years I served as an MTS (Member of Technical Staff) there were well past the glory years discussed in the book. Still, I remember being mesmerized by the small museum adjacent to the Murray Hill office's cavernous front lobby when I stepped in there for the first time while being there for the job interview, that displayed plaques describing six Nobel prizes the Bell Labs scientists had picked up in the previous decades. 

While I can summarize the book in few sentences saying it discusses the flood of innovations that came out of this institution (that forms the foundations of the modern communication system, and thus has touched practically every human being on the planet), the book is even more than that. So, I'd strongly encourage you to put it on your reading list. Though there were tens of thousands of employees who worked for Bell Labs at its peak, the author has intentionally chosen the approach of telling the story via a selected set of characters that ran the labs or were the leading scientists that delivered the stunning array of innovative products and ideas out of the lab. Mervin Kelly, Jim Fish, William Shockley, Claude Shannon, John Pierce and WIlliam Baker are the main characters that stand in for more than 1,200 PhDs and 15,000 workers it employed as early as in the 1960's. (Reminds me of the 4-part HBO miniseries Chernobyl I saw last year, in which hundreds of engineers & scientists were represented by one fictional female scientist to make the story telling easier. Interesting troupe.) 

In the early parts of the 20th century, the American Telephone & Telegraph (AT&T) was a US Govt approved monopoly that provided telephone service to customers all over the country. It was vertically integrated with Bell Labs at the bottom and Western Electric company in between, with AT&T at the top. Bell Labs did the research to design & develop the needed equipment, right from telephone cables/poles all the way up to the various incarnations of the switching systems. Western Electric is the manufacturing arm of the conglomerate that produced everything from individual telephone sets to switches, cables to provide an end-to-end telephone system solution, while AT&T ran the operation. The DoJ (Department of Justice) of the US Govt often looked at this monopoly with suspicion and had sued it to break it up periodically, i.e., every other decade. But the company will appease the Govt with some changes/concession to allow it to continue as this one massive organization. As a result, the money generated from the business could fund Bell Labs to support its research efforts exceedingly well, with stellar characters managing the labs and producing inventions that certainly benefited the public that wouldn't be possible otherwise. 


Huge business houses that are supported by Govts is not that unusual. From many public sectors companies (including telephone companies) in India to Chaebols in South Korea can be sighted as examples of this model. But none of them come anywhere close to the level of inventions/products Bell Labs delivered over the years. Can you believe vacuum tubes, transistors, electronic telephone switching systems, lasers, Telstar satellite, the whole field of Information Theory, Unix operating system, the programming language C, cell phone system, were a small subset of just this one institution's contributions to the world? Book tells this story amazingly well. Chapter where a very primitive satellite (that is just a spherical structure covered in a thin metallic wrapper to reflect any electrical signal coming in back towards earth) circling the planet is being tracked for the first time by Bell Labs scientists to test its viability to serve as a communication channel gave me goosebumps! It is humbling to realize ideas like cell phones should NOT have a dial tone like landline phones, so as to make more efficient use of the cell phone bandwidth, originated from here and subsequently proved to be a great fit for SMS texting. Naturally the transistor invented in Bell Labs is the backbone of the semiconductor industry even today and so I also saw my current employer Intel mentioned in multiple parts of the book (e.g. latest Intel devices that are size of a postage stamp come with about 2 billion transistors, and Intel manufactures about 10 billion transistors every second of every day!).

Eventually in the 1980s the conglomerate was split up. The local telephone companies formed what are called Baby Bells, while AT&T focused on the long-distance telephone service. The Western Electric company along with Bell Labs became Lucent Technologies that I joined after grad school. During my time, its stock price dropped from a high of about $80 to less than $2, which is all solemnly covered in the last chapter, including the formation of the spin off company Agere Systems that I belonged to in the early 2000's. Though it is sad to see such a great institution practically vanishing (now the name Bell Labs belongs to Alcatel-Lucent) along with most of its staff, with its buildings where I have worked in Murray Hill, NJ practically empty (and even worse the Holmdel, NJ facility, which was architecturally stunning when I had worked  occasionally, totally abandoned), author argues that the model had served its purpose and is not sustainable in today's age for various reasons. Concluding chapters are touching. Even if you are not in the field of telecom/computers, the content/prose/narration are all extremely accessible for anyone interested in reading this book. As the author says in the acknowledgments, the material, time span, stories are all unwieldy but have been put together in a nice and balanced manner. 

The organization I belong to in our office sends out internal email newsletter discussing interesting details/factoids about one team each month. Just by happenstance, yesterday they asked me for titbits about my team/site that they can include in next month's newsletter that would interest other employees in our company dispersed all over the world. I provided this small write-up closely tied to this book, along with the attached photos of a brick I have at home!
--------------------- 
Allentown, PA is a smaller Intel site with about 230 team members. Two decades back, the division we belonged to in Lucent Technologies (called Lucent Microelectronics) got spun off as a separate company called Agere Systems (in 2002). After few more M&A, some of us belong to Intel for the past 8 years, with blue blood running in our veins! The Western Electric manufacturing facility, which was part of AT&T/Lucent conglomerate had a manufacturing facility located in Allentown. It was the first facility to produce transistors on a large scale in the entire world. Silicon Valley in CA followed. About 15 years back when that building was taken down for new construction, the bricks were given out as souvenirs (and pen holder) to employees. Many of the old timers, like yours truly, have one of these at home!

Book review (Encounters with Einstein), movie trailer, podcast..


My friend Amit and I are longtime admirers of the early parts of 20th century that formed the Einstein era in Physics. We are certainly not unique since those decades are still considered the golden years of R&D in Physics and wax eloquently as such by many in several books and articles. So, earlier this year when he read & raved about this book titled "Encounters with Einstein And Other Essays on People, Places and Particles" by Werner Heisenberg, promptly ordered a paper copy. It is a short book of only about 140 pages and is made up of a small collection of essays, and transcription of some of his speeches. It is engaging/entertaining, particularly if you like reading about the development of physics during that time. 


This version is published by Princeton Science Library, which seems to have changed the original title of the book "Tradition in Science", perhaps to cash in on Einstein's fame! Amusing. Hence the first chapter still remains the old title of the book and discusses how progress in science tends to be extremely cumulative over decades and centuries. Starting from Greek philosophers and gliding through Copernicus, Galileo, author argues that Einstein wouldn't have been a great scientist if he had lived in the twelfth century, since the building blocks needed for his work wouldn't have been available to him then. Thus, even what problems we get to work on, is quite constrained by the time/history that precedes us. In a way, it reminded me of the notion of Overton Window in social sciences. 

Next two chapters delve into the development of Quantum Mechanics, particularly from Göttingen pov. It is impressive to read about all the interactions that went on between him, Neils Bohr, Pauli, Schrödinger, et al since we have heard of them only as historical legends that appear as larger than life figures in our high school physics classes. Copenhagen, Göttingen and Munich were the places where a lot of QM developments took place and they were all close to each other, allowing these researchers to exchange letters, travel to give lectures and so on. Before the age of Internet, how ideas evolved and people interacted to workout details of complex ideas is quite inspiring, that continues on the following two chapters related to elementary particle physics. The chapter actually describing his encounters with Einstein shows up only in the latter half of the book. Einstein was already a legend and so young Werner looks up to him, seeks his meeting/blessing for his ideas. But as we all know, Einstein was quite skeptical of QM and so though he invites Heisenberg to his home, has long discussions, expresses his doubts. 

As the WWII was ramping up, it is sad to see him describe as to how even Einstein's Theory of Relativity was opposed by Nazi regime, including some famous physicists claiming it as a Jewish conspiracy to which no major attention should be paid. At times Einstein even avoided giving lectures due to safety concerns and the author says he was even given a red leaflet when he went to attend a lecture, approved by the Govt., saying Theory of Relativity shouldn't be trusted since because of its Jewish origin. Heisenberg says he was so upset and disturbed by that smear campaign that he got very agitated and left the lecture, without even bothering to talk to Einstein. Subsequently Einstein had relocated to Princeton in the US, where Heisenberg meets him one more time in 1954 while he was on a lecture tour in the US. 

If we read up on Heisenberg himself, two kinds of images emerge. One is portraying him as a Nazi sympathizer, who worked for the regime. Other is that he is quite supportive of Jews and was against the Nazi regime, but naively thought it was just a party governing Germany for a while and will go away soon, while he continues his work in Physics. My take is the second one. 

Last couple of chapters on closed theories and scientist's journey into the abstraction, though written half a century ago, still gives some interesting insights into the process of scientific evolution. On the flip side, I found the prose to be quite stuffy and stilted. It was originally written in German. I was trying to find out who translated it into English but couldn't. Perhaps the author translated it himself. Sentences like, "The empirical correlate of compactness is the internal connectedness of many experiments, that is, the knowledge that a deviation of experience from theory in one experiment would also inevitably result in such deviation in many others." is quite off-putting by today's standards. 

Check it out if you are interested in this era/topic. I was looking at the cover image for a while to understand what it is. The back cover says it is "Nude Descending a Staircase No. 2". Oh, yes, nice cover!! Emoji
--------------------------------------- 
On a related note, check out this trailer for a new movie coming out in July of this year: 
Titled Oppenheimer, it is about the Manhattan Project. You all may know about director Christopher Nolan, who made Memento (badly copied as Gajini in Tamil/Hindi), Inception, Interstellar, Dunkirk, etc. He always plays with time, giving it a non-linear treatment in his scripts. He took it to an extreme in Tenet, making the movie a bit hard to follow. This trailer makes it look like the story telling is very linear in time, which is odd for him. Will have to see the movie to see how the script flows. I was also reminded of a low budget, made for TV documentary type movie on this topic titled Day One that I saw circa 1991, which was pretty good for its time.

On an unrelated note, since it is pleasant springtime in Pennsylvania, I went on a long jog this morning listening to an episode of Heavy Networking podcast (free to download/listen under the packetpushers.net umbrella of podcasts). It talked about WISP (Wireless Internet Service Provider) experiences that was simultaneously entertaining and reasonably technical. Consider listening to this episode if/when you get a chance: https://packetpushers.net/podcast/heavy-networking-679-mountaintop-networking-and-long-haul-wireless/

Even if you are not a nerd/hardcore techie, you may gather some interesting stories about the impact of wild horses on communication networks, and BATMAN protocol that will be good fodder for your next family get together or team lunch! 🙂
