Sam Pitroda: An Interview

This interview appeared in India Abroad, New York, Oct 21, 2011

"We need to redesign the nation"

 

Sam Pitroda has advised more than half a dozen prime ministers of India over the last three decades regarding technology applications and policy. Shivanand Kanavi captures the highlights of this rich experience in a conversation.


How did your engagement with government of India as a technology advisor start nearly thirty years ago?

In the early 80`s computers were just becoming more and more viable in terms of desktop, that was the time Rajiv Gandhi came into the mainstream of politics as a young MP in India. He was visionary and was himself technology savvy. He saw that computers could play very imp role. I had background in telecom, IT, and software in the US and I was also young and because of my background in telecom, I decided to look at telecom as an instrument of change in nation building. 

How did C-DOT come along?

Mrs Gandhi and Rajiv Gandhi gave me an opportunity to set up C-DOT (Center for Development of Telematics) to develop indigenous technology for India’s effort to digitize networks. Then we had electro-mechanicals [switches]. However we were going digital so we needed products, and one idea was to get products and technologies from MNCs like Alcatel and another approach was to develop indigenously using Indian talent  to meet Indian needs like rural telephony, smaller exchange that can withstand Indian climate; dust; high temp and all of that, so my entry into India was to essentially focus on digital networks, develop rural telecom through C-DOT.

Were you not part of the “computer boys” of Rajiv Gandhi’s era?

Collectively we all felt computers have a role to play not only in telecom but also in other areas and if we really want people to see the benefits of IT then we need to apply it quickly in areas where average Indian could see the advantage. Otherwise they would all say, look this is all fancy stuff only for the rich, urban, elite etc. Many used to say ‘what does this guy know about rural areas? Rural India is very different’. People used to tell me you should work on agriculture, drinking water and sanitation. I used to say ‘you are right, but I don’t know anything about it. You need to find an agriculture or a water expert. I happen to know about IT & telecom so I can only work on it, my knowledge is limited, but there are so many other things going on in the world like biotech, nanotech I don’t know anything about it so I have to focus on what I know and someone else has to focus on other areas’.

How did the idea of computerisation of Indian railways’ passenger reservation system, which celebrates s Silver Jubilee this year, originate? That actually changed people’s perceptions on the ground.

Rajiv was convinced that technology can be an instrument of change. We said we must look for area which affects large number of people. Many people wait at the railway stations e.g. a person is waiting at the railway station window no 6 to get a ticket to Nagpur and you get all the way up to the line and when you say you want a ticket to Nagpur you are told that you have to go to window no 7 and so you have to start all over again. The hassle of getting railway ticket, going to station for booking it etc all that was a painful experience for every citizen. So we thought how about using this for railway reservation.

Problem however were the unions. They were going to be against it as the general impression was that computers take away jobs and that automation is not good. ‘Automation is for the west not for India and India should not automate anything. We should focus on labour intensive technology. We have more people we need to create more jobs so manual is the only way to do it’.

How did you overcome the resistance to the idea?

Unions reacted saying ‘no way’ we will allow this to happen. We started dialogue with unions saying this is important in the long-run and in passengers’ interest. In one of the conversations somebody figured out that if we put computers we would need to have Air-Conditioned rooms so people will benefit from the better work conditions and environments. So we said let’s try it in some place and create a POC (Proof Of Concept). We told the board, ‘give us a slot to try and if you are not happy, unions are not happy then we will revisit’. So people agreed that we should try. Dr P P Gupta the then CMD of CMC was very happy. He was given the mandate to prove the concept. CMC was seen as a new organization; dynamic and innovative. We had the talent in CMC to do this kind of things. After a lot of effort, when we showed the unions that it can work, then we saw change.

In India  at that point in time we also didn’t have the capabilities, if there had been RFPs then they would have surely gone to the IBMs of the world but then the mood was ‘indigenous development’. When proved the concept, people saw it and said consumer would substantially benefit from it as they won’t have to go through the hassle, but then the challenge was how we did it. Even today revenue-wise freight is more important, but we wanted to look at benefit for consumer because then the acceptance for computers overall at a national level would be better, so in a sense it was a railway project but it was more than that. It was a project to prove to all stakeholders; our consumers in many fields and unions in many fields that automation is not bad. Computers are not bad. They will upgrade the jobs. Now your people will work in AC. All those things were critical.

What about wider adoption of IT in the railway operations?

That’s how the CRIS (Centre for Railway Information Systems) was born. Besides reservation there are lots of other things but it took 20yrs for people to embrace this whole idea in a big way. Reservation and ticketing was an instant success. People thought it was a miracle and I would say this was the first grand success for IT in India. By then C-DOT was rolling and exchanges and telecom modernisation were seen as the important.

Going back to the railways story, don’t you think we could use technology to make them safer?

In the Indian Railways, we have huge possibility to use IT for travelling, traffic billing, we have built the highway we want satellite based or GSM based real time monitoring anti-collision device etc. All of that it is very simple. Indian Railway has 40,000 kms of its own optical fibre they are trying to put another 10000 so IT is becoming important in railways in traffic building. Many people die at railway crossings everywhere. We could give the person manning it this little device, which listens to the train coming in and gives an alarm signal that train coming so get off the track. Technology should be used to prevent such deaths. Very soon many technology initiatives of Indian railways are going to be announced.

There were also other technology missions….

Yes more technology missions came in where we could take technology to address the routine problems of people related to water, literacy, immunization, edible oil, and telecom. These were the 5 missions to which we added dairy development as the 6th mission. Then we started changing the mindsets. That was a big accomplishment in a country of then 800 million people-to convince people that technology is something that is positive. Technology is not bad it is not urban, exotic, fancy. To me in those 5 years this was the main accomplishment and it will benefit our young.

What are your current preoccupations?

Today we are nation of connected millions, unfortunately people don’t quiet appreciate this big revolution that has happened in the history of India. So far we were a nation of unconnected millions, now we are all connected in some fashion. You can reach Kashmir, Mizoram, Kanya Kumari just like that. So what does it mean for a nation going forward? How do you redesign the strategies  based on connectivity for development? Should we go around doing the same thing that we have done in the past and not notice the fact that we are a nation of a billion connected now? Something huge happened in last decade let’s sit back and take advantage of it. How do we do everything we do today, differently? I think that’s the main challenge how do we examine governance, public services.

So what it means is that now we need to redesign the nation, if I may use that word. How do we get birth certificate, how do we get land record, how we can file a police report. Today when I file a police report in kerala somebody in Maharashtra can’t read it due to different format, different column, and names do we standardize that so that when a police report is filed in Kerala  it is available in Maharashtra i.e. anybody in Maharashtra can read it and can we do it online because we are connected? Everything we do has to be rethought.

In a sense everything we do today is obsolete; people say we don’t have enough professors, with connectivity we can take a great professor from IIT Kharagpur and broadcast to 2000 colleges. All of that is possible now, distance learning, e-governance all of this can be a reality.  Can we provide for video conferencing so that people don’t have to travel hours for a 5 mins meeting? What we are doing now, could have been done on Skype. So we can avoid you travelling for an hour and half to reach this place to see me. All of these things are possible but this will take time to change the mindset of people. I was once telling PM, “a lot of people come to see you. You could schedule a 10 min interview with a person in Kerala that individual gets up in the morning takes a flight goes to PM’s house where 15 people are waiting he is always hassled it’s going to be 7:30 then 7:45 then you meet for 5 mins and he says “Sir ye problem hai”( Sir, such and such is a problem).. Poor guy has lost whole day so much petrol so much time... you could do the same on video conferencing”.

So going back to the original thought we are nation of connected million and we need to do things differently we need to use cameras, videos, scanning to reduce travel you know to manage our cities better. We cannot manage our cities the way we have been managing. For example, today everybody is focused on urbanisation but their idea is Mumbai has 18 million people and it will become 26 million in........ But we don’t want extrapolation. We need restructuring. How will I use GIS (Geographical Information System) to make Mumbai better. How to use scanners to make Mumbai secure? We really need to make our cities smarter. Come up with different ideas how we improve our slums.

Where is the resistance now?

The government in a sense is not technology friendly. There are young individuals like Jayaram Ramesh’s of the world, who are tech savvy, but there are secretaries in IT who don’t use computers. The Department of Electronics uses manual files to make decisions; they should computerize their files, how many people in Department of Electronics use computers to make decisions. They are taking decisions on technology but they are using manual files. But that’s the system we have. You never see people in Indian government taking notes on a laptop, how many ministers know how to use laptops. You have to be connected you have to be able to read your e-mails, you can’t write or call your secretary and say “dictate karta hoon note likho” (will dictate a letter note it down) and then mail it and then wait for the reply. Those days are over, we are a connected people. We have built this nation in the last 20 years based on technology. Today if we have over $300 billion forex reserve it is only because of technology. IT has given us great deal of global recognition, lots of global companies of our own, lots of success stories, our advantage is we are in large numbers.

Archaeo-Metallurgy, Dr Baldev Raj, A Conversation


From: Ghadar Jari Hai, Vol 5, Issue 2

Dr Baldev Raj

Archaeo-metallurgy: Where Gods come alive

 
Dr Baldev Raj is a highly distinguished metallurgist and nuclear scientist. He was till recently the Director of Indira Gandhi Centre for Advanced Research of the Department of Atomic Energy at Kalpakkam. He is the current President of the prestigious Indian National Academy of Engineering and has a very large number of research publications to his credit and has been honoured by many countries. He has also co-authored, “Where gods come alive: A monograph on the bronze icons of South India” (2000, Vigyan Prasar). Shivanand Kanavi met him at the Prototype Fast Breeder Reactor facility, Kalpakkam recently and spoke to him about how he got to employ his considerable skills as a metallurgist in studying some objects from our ancient and medieval past and what we can learn from it.

How did you get interested in archaeo-metallurgy? When did it start?

It is a strange coincidence. Prof. C V Sundaram was our director at Indira Gandhi Centre for Advanced Research. There was a fellow of IISc, Dr Paramsivan, who did his PhD in archaeo-metallurgy six decades back! He came to C V Sundaram and said he was interested in the characterisation of bronzes. Prof Sundaram called me (it was the late seventies-early eighties) and said you are doing non-destructive testing, why don’t you work with Prof Paramsivan? I said yes. We then went to the south Indian temples where the bronzes are, and also went to museums which gave us permission to bring them to the lab. The very first results were welcomed and appreciated. Dr V S Arunachalam was the scientific advisor to Raksha Mantri (Defence Minister) at the time and had keen interest in that. He was encouraging and said that good science should be done and that just saying that we have a great heritage does not help. That was the trigger point. Then I got interested in the iron pillar, I got interested in icons, in the temple at Mahabalipuram, and so on. Now I am interested in the characterisation of Ajanta and Ellora using Raman spectroscopy. We also studied the musical pillars of Madurai, which appeared in the cover of the Accoustic Journal of the USA. Now I am as interested in archaeo-metallurgy as nuclear metallurgy.

SK: To begin with, can you explain what is archaeo-metallurgy and why it is important?

BR: Those metal objects were made a long time back, maybe 2000 years or 700 years or 200 years ago.
The very conceptualisation of those objects happened with the knowledge base of that time, and the inspiration was even greater than the knowledge base. Today there may be a much greater knowledge base, but how many things are done with that kind of inspiration? Only such things stand the test of time. We get the knowledge of technology of that time from the scriptures but everything is not mentioned. It is a broad description. They had mastered the technology without the characterisation tools or modelling. So, archaeo-metallurgy is digging into the past metallurgy through reverse engineering. It is very fascinating.
When you still find gaps, you leave the hypotheses open. Sometimes the historians, sometimes the experts in arts, bridge the gap but you provide them the component of S&T (Science & Technology). It becomes useful to them also. In India fortunately there are a number of artefacts for archaeo-metallurgy. In fact one needs to broaden metallurgy to include materials science. Then you cover almost everything — stone, paintings and so on.

SK: In terms of Indian heritage there is a lot of ignorance and, because of colonisation, an inferiority complex also. One tends to think that Europe produced everything. This type of scientific research into our past which describes complex technologies being employed in ancient and medieval India changes that perception.

BR: Earlier nobody was interested in India but today people take you seriously. Of course nobody is interested in hearing claims which have epics as the basis. But if you can use scientific methods then people in the outside world listen. Then even the enlightened tourists would be interested. Take Yoga for example. Because a lot of serious people took up writing, teaching, popularising Yoga (and a few might have misused it also) it enhanced the position of Yoga internationally. Even our work on a scientific basis of Indian science and technology would lift the reputation of India from a low cost centre of cheap manufacture to a people who are capable of innovative and inspirational work. One can then have a robust story to engage the rest of the world with confidence. Even when we studied the south Indian bronzes it was from that point of view.

SK: What did you learn and conclude from that? What got you interested in the south Indian bronzes?

BR: One factor was beauty. The artists were involved in producing more than the daily necessities. How could they produce something which was so inspirational? Bronze technology was mature but nobody had produced such aesthetic objects. They were inspired by the scriptures. Castings at that time were made using bee wax but how did they give them such perfect shape and shine? I think they probably did not realise at that time that they were creating something almost perfect. Material was also not very abundant at that time — they had to re-melt when things went wrong. But if they created something beautiful they incarnated it and installed it in a temple. When I studied the bronzes, I found that they had very few defects whereas even in today’s 21st century investment casting there are so many defects in small pieces! The conclusion I drew is that there are certain things in human creation which come by commitment, which do not come from the technology or machines you use!
They were inspired by the fact that they were creating images of god, and second was the fear of the king who had commissioned the work. In the process they created perfection. They did not even have ways to check for defects that we have. The products were an unparalleled combination of beauty and technology. We have compared with many other things of that time in the world.

SK: What did you learn from the study of the Iron pillar?

BR: Nowadays we are talking about cost effective technology and actually the iron pillar is one such example. It is ordinary iron of no fancy alloy composition, but it has survived 2000 years! That is great science. The anti-corrosion property has been studied well. It is primarily because of the phosphide layer, which regenerates in a few months even if you remove it.

SK: It is said that during Alexander’s time India had steel technology.

BR: Yes, Wootz steel.

SK: Have they figured out how Wootz steel was produced?

BR: We have figured out its micro structure but not been able to reverse engineer it.

SK: Has enough field work been done to find any people with memories of these technologies?

BR: In the case of south Indian bronzes it has been done. The last of the persons who actually knew of it passed away a few years back. Fortunately, we recorded his interview with photographs etc. Dr Sharada Srinivasan and Prof S Ranganathan have done considerable work on Wootz steel.

SK: In building the story of Indian science and technology people have largely depended on epics and the Puranas etc., which many Indians also may not believe, but the material artefacts are indisputable. What we can reconstruct forensically from them would be sound and verifiable.

BR: Yes it would be verifiable by any country. Science has to withstand questions and has to be verifiable by anyone independently. If more and more people take this up as a hobby, it will bring them closer to their civilisation and culture also.
Today when we talk of being global, it sounds very vague. Nobody knows what that means. This kind of work would bind them to their culture and also look at global possibilities. I think this should be taken up by more and more good people as a hobby. Not that one should set up a big lab for archaeo-metallurgy. Every lab can do it wherever there is interest and specialists. Take the Taj Mahal for example, one can do a lot there from the archaeo materials point of view. It has been explored to a great extent from the point of view of architecture. For example, if I ask the question, what is the remaining life of the Taj, what is the answer? Are we expecting it to stand till eternity? Why can’t we explore it? We will learn along the way. We need to put together a small group of 10-20 people comprising civil engineers, material scientists, experts in characterisation etc. That kind of work would attract the attention of anybody in the world!

SK: When I first visited the Taj Mahal what struck me was not its beauty but the technology involved in it. The minarets are conical. The angle of the cone is so small that only when you look at it from far do you notice it. So how did they machine the marble which has been kept in C-sections which are cylindrical but also have a small conical slope? This has been done with such high accuracy that each one sits perfectly on the next one. Obviously this cannot be done by hand burnishing. So what kind of machining did they do to those marbles? Moreover it is over 300 years old. In the period since then there must have been several serious seismic shocks, then how has this structure with-stood it? How did they earthquake proof it?

BR: One should study its foundation, using non-destructive testing methods. Also during seismic events one can measure the vibrations and calculate in reverse and estimate what kind of foundation it must be sitting on. There are a whole lot of issues.

SK: When I visited some caves in Maharashtra in Lonavala, in Ajanta, in Sahyadris or even in Mumbai in Mahakali, Jogeshwari or Elephanta etc.- I had many questions. Some of them were built 1500 years ago in the Satavahana period. I have always wondered how they cut the hard rock. What kind of metallic tools were used? I have asked archaeologists but have not got answers. Similarly, how was the Kailash temple at Ellora built from a monolith? What kind of project management and planning did they do to achieve the outcome?

BR: There are a lot of questions. It is very exciting and one does not know the answers. One has to spend quite a bit of time and research in a step by step manner to get plausible answers.

SK: Thank you Dr Baldev Raj. This has been a very stimulating conversation.
