Reinvent, Regroup and Re-think


I came upon a very insightful and inspiring speech  by Anand Mahindra, vice chairman and managing director of Mahindra & Mahindra. While this speech was delivered  in 2008 at Nasscom Leadership Summit, it still holds and will continue to hold relevance for Indian economy in the time to come, as we step into 2012. I am reproducing the complete speech below -


In order to walk the talk, every time I’m asked to speak at a conference, I have made it a default option to ask what the audience–my customers–might expect of me. And so I found myself wondering what this conclave of IT wizards expects from a predominantly right-brained character like myself. You certainly haven’t called me here to deliver a sermon on technology. And I wouldn’t even risk doing that with Nandan (Nilekani) and Kiran (Karnik) sharing the dais!

Of course, I might have been able to do that by getting one of my IT colleagues to write this speech, but then it would have been comprehensible to you, but incomprehensible to me!

And although the title of this session is ‘Building a Knowledge Economy for Growth’, I believe that a) All of you out there have helped build the foundations of a knowledge economy, so again, you don’t need me to pontificate to you about that and b) I think there are some urgent pressures and imperatives the industry has to deal with at this point.

So, I’m going to talk about something completely different: I will talk about the Trimurti.

Most of the Indians in this audience will know the Trimurti – the trinity in Indian mythology of Brahma the creator, Vishnu the sustainer and Shiva the destroyer. There is a wonderful depiction of this in stone, just ten kilometers across the bay, at Elephanta. Both as a businessman, and as someone who tends to see life in visual images, the Trimurti reminds me of India’s IT industry. Think of it.

You people have gone through a stage, where like Brahma, you created something out of nothing. You created a new and global industry. You created a service sector that is today, a major pillar of our GDP. But most importantly, you created a perception of a new India, both in the world and in Indian hearts and minds.

CK Prahalad once told me that in universities in America today, there are almost unfairly high expectations from Indian students, because there is a huge perception that all Indian students are brilliant, outstanding. You created that perception. And within India, what you created was self-belief. You showed us what Indians could do, and now the rest of India believes that Indians can do anything. Brahma created a physical landscape; you sowed the seeds of a new mental and psychological landscape. In that sense, you are truly the Brahmas of the age of liberalisation.

But creation is only the first phase. You then have to move on to the next phase of sustaining that creation – to the realm of Vishnu the preserver. Creation is a one-time affair. Sustaining that creation is obviously a longer haul, subject to many attacks and crises. Perhaps that is why Vishnu comes not in one, but in ten incarnations.
Every time there is a new danger, he changes his avatar to a form best suited to meet that danger. At various times he has come as a fish, as a tortoise, as a dwarf. But his most interesting avatar came when he had to fight the demon Hiranyakashyap. Hiranyakashyap was a bad guy, who had obtained an amazing boon from the gods. Neither man nor beast could kill him; he could not be killed by daylight or at nighttime, within his home or outside it, on the ground or in the sky. All this made him pretty invincible – he went on a rampage, and only Vishnu could tackle him.

The IT industry today faces challenges every bit as complex as those Hiranyakashyap posed for Vishnu. It is hit by a macroeconomic tsunami of adverse currency changes, rapidly escalating costs in both salaries and infrastructure and inadequate talent pools below the tier 1 and 2 institutions.

At the Company level, firms are begin to feel the penalties of poor differentiation and lack of focus (trying to be all things to all people); and an over-emphasis on high volumes and price competition. Suddenly, the industry seems to have fallen off its pedestal; You are facing your very own Hiranyakashyap.

It’s interesting to see how Vishnu dealt with him. How do you destroy someone who can’t be killed by man or beast, inside or outside, by day or night etc etc. The demon pretty much had all bases covered. So Vishnu took on the Narasimha avatar to bypass the boon. Narasimha was a hybrid creature, half man half lion, and therefore neither man nor beast. He killed Hiranyakashyap at twilight, which is neither day nor night. He killed him in the courtyard, which is neither inside a house nor outside it. And he killed the demon by placing him across his knee and tearing him apart, thus circumventing the terms of the boon that he could not be killed
either on the ground or in the sky. Now that’s what I call an innovative algorithm!

So what are the lessons for the IT industry in this story? Well, the first thing Vishnu did was to reinvent himself. It was not the gentle and contemplative Vishnu who fought Hiranyakashyap – it was the fearsome Narasimha avatar. Vishnu reinvented himself to suit the circumstances. The circumstances have changed drastically. Reinvent yourselves.

Do I have all the answers on the modes of re-invention? No, obviously not, otherwise I’d be out there filing patents, although I can suggest two broad approaches.

First, why don’t we design business models that challenge traditional industry approaches and then transform our organizations, people and processes to execute. If we simply keep knocking on the doors of clients with our traditional offshoring options, we’ll meet the fate of hearing aid salespersons: our best customers won’t hear the doobell!

For example, software-on-demand and open source models changed the rules of the software game. Can we not try to change the rules of the game this time around? Why didn’t we invent Zoom technology or Virtualisation? Thus far, India’s brand of innovation has been identified with the IT industry, but is it truly innovative. Is it really game changing? Ironically, you can now look to the old smokestack industries for inspiration.

A few weeks ago, an Indian car company made a game-changing move. Maybe the Nano will ultimately not retail for a hundred thousand rupees. Maybe it won’t have great margins, or replace as many motorcycles as it would like to, but it was a game changing move; it fired a shot that was heard around the world. Can the IT world make any such claim?

There was an old saying, apparently adopted by the IT industry, that the secret of success is to jump every time opportunity knocks. And how do you know when opportunity knocks? You don’t, you just keep jumping!

So when are we going to stop simply jumping every time a client seems to sneeze, and actually create products and IP that become their own opportunities?

Let’s look at new areas where India may have natural advantage. I remember C.K Prahlad telling us that we didn’t realize how important it was to leverage emerging innovation ecosystems in our country. He gave us the example of how, due to a fortunate coincidence, India’s IT and automotive industries were situated in roughly the same geographic clusters. So why wasn’t, according to Michael Porter’s competitive theories, a world beating automotive telematics industry taking shape here.

Why aren’t IT companies using the massive potential of India’s soft power, the film and TV business to exploit technological dominance of what Telco’s call the ‘last mile’ but is actually the ‘first mile’ in the brave new interactive world?

Secondly, why don’t we try to focus on a vertical industry (e.g., telecom) or horizontal domain (e.g., supply chain management) selecting the key dimensions of competitive differentiation – product vs. service, breadth vs. depth, speed of delivery, customer service responsiveness, fixed or outcome-based pricing, proprietary technology or intellectual property, and so on.

And let’s be prepared to make hard decisions along the way – change people who don’t fit, walk away from businesses that doesn’t fit.

It’s essential, while attempting this, however, to recognize that focus, differentiation and brand building require time and investment. Selling value or doing business differently than the norm tends to elongate sales cycles, which tends to put pressure on cash flow and we need to resist the temptation to broaden our offerings or slash prices just to win the business and keep people busy.

Along with re-invention, during the course of reinventing himself, Vishnu figured out the loopholes in the boon, and regrouped his physical and mental aspects to take advantage of these loopholes. That’s something the IT industry can do as well. Its often been pointed out that in the Chinese word for crisis is also the Chinese word for opportunity I love that mindset. I truly believe that the adverse rate of the dollar can be viewed as the glass half empty or the glass half full. Sure it affects margins. But it’s also a chance to take advantage of the loophole and buy yourselves what you don’t have, so that you can regroup your structure to meet the challenge.

To me the fact that our currency is more valuable and our price earnings ratios are still higher than average, means that we can acquire the front-ends and the large IT businesses that we never thought we could before. And the bigger the better. If people are egging us on to leapfrog, then they should also cheer as you bid for companies that seem bigger fish than you. It’s happening all the time today in the manufacturing sector-Tata Corus being the stellar example-and we at Mahindra, while starting from scratch, have inorganically compiled together a portfolio of acquisitions that make us the fourth largest steel forging company in the world today.
This is not without historical precedent. If you look at Japan and South Korea, both of them went through a phase of enduring the worlds’ skepticism, then painstakingly building strong and competent domestic businesses, and then on the back of global liquidity support and strong price earnings ratios, compressing time by acquiring global firms and their customer credibility.

In effect, by acquiring the strengths and skill sets you need, you will regroup your profile and create a new entity, which can vanquish your challenges as effectively as Vishnu vanquished Hiranyakashyap.

And finally, while reinventing yourselves, you will have to bring in some of the aspects of the third element of the Trimurti – that of Shiva the destroyer. Destroy for example the premise that cost arbitrage is the way to go.  Recognize that the low cost, high volume offshore outsourcing battle has already been fought and won. Often, when strategic frames grow rigid, companies, like countries, tend to keep fighting the LAST war. If you are not already on the winners list, you need to think of other ways to compete  on value and differentiation, rather than price and scale.

Destroy the premise that success comes only from size, and desist from comparisons with other Indian companies. There are still many IT companies in India who define success as “we want to be one of the top ten Indian IT companies”. Why not, for example, “we want to be the world’s #1 banking back office solutions provider”?

And lastly, perhaps the time has come to destroy the notion that the world may be your oyster but India is not. There is a huge domestic market in middle class and corporate India that has not been plumbed. Even selling to the bottom of the pyramid is profitable today. But it needs a creative destruction of the current mindset and a re-think on many of the assumptions we hold dear.

So, in conclusion, perhaps there really isn’t that much distance between avatars in the mythological sense and avatars in the technology sense. Perhaps they are both symbolic expressions of the same reality. In their different ways, they both underline the same message – that it is necessary in any situation to reinvent, regroup and re-think our way out of whatever challenges confront us.

I’d like to close with one of my favourite quotes-such a favourite, that I can’t even remember where I first read it:

My father thought the world would be same;
My children, however, wake up EVERY day thinking the world will be different.
Let’s begin emulating our children. Time to wake up and make the world different.

Between Perception and Reality

Don't we remember seeing shapes in the clouds morphing into a human face or recognizable objects? something like this.
Or, do you recall the chill that ran up your spine when you saw a lingering human figure in the black silhouette of the swaying tree branches? You might pass this up as mere illusion, something that occurs when your mind plays tricks on you. Then consider more of such cases. Do you remember a game in our childhood where we use to spot abstract figures or objects in the messy ink splatters formed between two pages of our notebooks (the famous Rorschach Inkblot test)?.  
I am sure you won't forget this one. The famous 'Face on Mars' - a part of its Cydonia region. The picture was taken by the Viking 1 orbiter spacecraft and was released by NASA/JPL on July 25, 1976 upon seeing which people mistaken it for existence of Alien civilization on Mars. Lastly, not to forget the several instances of UFO sightings and numerous reportings on appearances of ghost images in videos and photos.

Wonder what are these? Simple illusions or cases of pathological disorders in the brain? No, don't worry you haven't lost your wits yet. I chanced upon this interesting article by Dr. John W. Hoopes, Ph.D., an Associate Professor in the Anthropology Department at the University of Kansas, and was astonished to learn that this is a quite common phenomenon and is attributed to our error of perception, called Apophenia. Based on the recent researches and experiments, specialists in the field of Psychology, psychoanalysis and neurobiology are trying to understand this condition and its related effects. Apophenia is a tendency to interpret or see patterns or connections in a random or meaningless data. In fact the examples we just described are a special case called Pareidolia. which is visual Apophenia. Dr. Hoopes tells that Apophenia is a result of process of Human Cognitive evolution. In words of Carl Segan, Human mind is hard-wired to recognize faces from birth and this ability allows us to use only minimal details such as outline of an object or a shape to recognize or interpret random images or patterns as faces from a distance, and even in poor visibility conditions.

Those of you who have read the famous book 'Fooled by Randomness' by Nassim Nicholas Taleb would recollect that Taleb talks about the cognitive biases, which is a general term used to describe may distortions in human mind that result in the errors in its judgmental capabilities. We are all victims of cognitive biases. We stake our life-savings in the Stock Market trusting on the hunches of an investment analyst who claims to "foresee" the upcoming market drift in its random movements. This is an example of hindsight bias. The analyst constructs financial models that claim to predict the market movements based on historical data which in a way "seem" to fit a pattern. Or a 'confirmation bias' which makes us see only that information which confirms our preconceptions or hypotheses regardless of whether the information is true. This shows that there is some common footing between Apophenia and cognitive biases. Dr. Hoopes apparently hold that "Apophenia is not usually pathological but can become so in schizophrenia, when pattern recognition and interpretation run wild".

Hollywood has exploited this idea in movies such as " A Beautiful Mind" about John Nash, the nobel laureate mathematician and founder of the field of Game theory, who is tricked by his mind into believing that he has been hired by US department of defense to detect and decode patterns in magazines and newspapers which supposedly is the clandestine mode of communication for Russians. In pursuit of doing so he becomes preoccupied with it and loses his sanity. Similarly, in psychological thriller "Pi", a debut movie by Darren Aronofsky, the protagonist, a number theorists, strongly believes in the premise that every thing in this nature can be understood by numbers. He becomes obsessed with finding predictable patterns within the stock market movements inevitably lingering on the verge of madness.

Pattern recognition and interpretation is fundamental to human existence. Conditions such as Apophenia or Pareidolia gives us a glimpse of the eerie propensities of Human mind which pushes us to the fringes of our understanding of perception and reality.

Indian TV Soaps - Serial killers

Falling prey to an onslaught of Indian Television Soap-operas could proved to be the single life sucking experience for an average Indian male. Watching an Indian TV soaps could well be both mentally harrowing and emotionally draining experience. This is completely from my own humble experience after having left with no option but to watch them for fairly substantial no. of hours of their airing time everyday. Mentally harrowing because your gray cells would want to explode as you watch it and feels like you are eternally stuck  with a "WHY ME" syndrome. Emotionally draining as you are exposed to insistent barrage of appalling, out of the world histrionics packed with melodrama and conversational non-sequiturs that leave people scratching their heads or make them numb with emotional distress. If you are one of such victims, you would empathize with it more as your own agony plays out before your eyes while reading this.

Indian Soaps are examples of intelligent TV programming addictive for those who want to watch it,with never ending story plots, each one deceiving to offer a fresh storyline with an embedded social message in their promos but only to fallback on the same old cliches after few episodes. As my version of the slogan of one channel says "Rishta Nahin, Soch Wohi" literally "no relation, same cerebration". This is nothing but an old trick to let the viewers especially housewives fall prey and remain glued to the TV sets in anticipation of something new and interesting.

Every soap supposedly portrays a middle class family that would have mansions with bright ornate walls, marble flooring, and giant decorative pillars, inter-spread with silken curtains impelling Indian economists to revisit their poverty line threshold estimates. TV channels have started a irritating new trend to rope in Salman Khan in every other promotional venture for new reality shows, or Soaps. I freak out whenever see this guy with his perpetually swollen puffy eyes, terribly bad Hindi skills and utterly disgusting hip-gyrating movements.

These soaps would have carefully chosen unusually long titles preferably lines from a popular Hindi song, with first line played up and rest displayed in cleverly indistinguishable case affixed in the end during the promos and the song is repeatedly played in the background. The female characters in these soaps are incredulously made up and decked up everytime and everywhere (including unusual places as kitchen, bedrooms, while sleeping!!). While this buffoonary being enacted on screen, one could spot some peculiarly distinctive background sounds which adds to this dramatic effect -
  1. For all the wicked wives, bahus and sister-in-laws, a signature tune plays out in the background whenever they enter the scene or when their evil, conniving thoughts set into motion (a lot of thinking aloud goes with it!!). Here there is a unusually heavy emphasis on use of indian percussions with characteristically repetitive thumping which builds up in a huge crescendo and then collapses
  2. then goes a peculiar crashing cymbal sound for occasional accents or shocking revelations accompanied by camera swooshing and swishing movements from all directions with every possible angles converging into the contorted and over-expressive faces of casts. Sudden camera zooms,  awkwardly abrupt fast and slow motions (usually within a second from each other) will follow.
  3. finally the virtuous bahu signature background tune that would have probably a piece of violine or sitar with lot of chorus effect (something like lalla la lala)
No doubt that all these 'subtle refinements' would requires equally monumental efforts and commitment from actors.

I found that sometimes male characters in these serials even would have effeminate tendencies. In one such soap, the only Son of an orthodox Marwadi family has been brought up in a overly protective environment and we are made to realize this during the episodes when his mother cries out and calls him an abominably annoying "MUNNA" several times. Sometime it becomes difficult to tell if it is "MUNNA" or "MUNNI" she is addressing to...

Well, this is eternally unending saga of buffoonery which has potential to bring forth an entire blog in itself. I hope some of you would have gotten some clue about my condition and would commiserate with my feelings.


For those of you who are not deterred but rather felt sufficiently motivated after reading this post and please have a look at guide on "UNDERSTAND INDIAN SOAP OPERAS"

A Hollow Eulogy

Government is celebrating 125th anniversary of Indian Mathematician Srinivasa ramanujan and observing his birthday as the National Mathematics Day. PM has also declared year 2012 as the National Mathematics Year. Reportedly, Robert Kanigel who is the author of The Man Who Knew Infinity (1991), first ever complete biography by an American author, was in India on an invitation from the Indian Academy of Sciences to give lectures as part of Ramanujan's birth  anniversary celebrations. The Hindu has published his interview here. I happened to read this book when I was pursuing post graduation. With due respect to Kanigel & all those foreign authors who painstakingly research and publish about India and Indians, I somehow not comfortable with this fact of a foreigner writing  so authoritatively about an Indian talent while we Indians remain alarmingly ignorant of our own scientific legacy.

Notwithstanding the amount and quality of research in such works, they still lack the cultural and social perspectives and remain confined to being nothing more than a skewed portrayal through a western lens.This arouses deeper questions. Why we Indian's are so poor in recognizing our own cultural legacy, our own historical achievements? Why do we need west to make us realize the true value of our accomplishments? What prevents us to be the first to write about our geniuses and our history and let the world know about it? Understand that We Indians have always been miserable in keeping the record of our own history. This is why Prof ramachandra Guha aptly raises this concern when he explored the central question of why historians of Asia do not write biographies and why they should duing a seminar in JNU.His main argument was that Asia has produced an interesting range of personalities and has a very rich literary tradition, but it is paradoxical why historians of Asia have not indulged in writing biographies. Among the probable reasons cited by Guha was the burden of  religious inheritance in Hinduism and Buddhism and the belief in the cycle of rebirth. He further adds that an indifference to record keeping also precluded the writing of biography.

I wonder why do we always need a western cultural, literary or scientific yardstick to benchmark our accomplishments? Why couldn't a Ramanujan recognized by local authorities when he endured such hardships at home. Why did it take a GH Hardy sitting in England to recognize the talent in him? Understand that real talent needs right conditions at home to flourish. Only in stable economic and social conditions would they be able to seek recognition for their work.If such conditions are hard to come by in a politically, socially and economically unstable milieu, they migrate. We witnessed this during second WW when  an overwhelming number of scientists and artists migrated from European countries of German occupations.This is not a new phenomenon for India too. Could this be exactly the reason why a Sun micro systems or a Hotmail got set up outside India? Or is this the reason why we have so many reasons to vehemently eulogize Non-resident Indian talents and their achievements while back home our scientific or artistic talent remains largely  unacknowledged?

A Racy Debate

Whenever India set out to achieve something out of the ordinary such as hosting a Formula I sporting events, you are bound to hear voices and opinions that swing from eulogistic or laudatory to downright caustic and debasing. Every voice, every opinion mirrors a different India.This is bound to happen in a democratic country like india where everyone has a right to voice an opinion. But it is also true that the its equally difficult to see those opinions converging into  a singular unanimous voice. As it is said, if something is true about India, then the opposite is also true. And these contradictions glare out at you and become more apparent whenever an attempt such as Formula I is made to project an image of India that is too far from reality.

The perception of the reality is this. Indian society is made up of haves and have nots.  The "haves" will always be the ones who are the major stakeholders in such events and would eventually be benefitted by it. They would be the ones who would ride on the "India coming of age" wave. The "have nots" wouldn't have time beyond their daily act of survival and would probably pass this as another quirky affair of the "haves". No wait, then there is a third category, who are a confused lot. They do not know what is meant by priority for a developing nation, they have not yet developed mental faculty to understand the pro and cons of such events and their cultural fitment.They just want to seize the moment and perpetually be in a state of delirium.

There is a lot of generalization in there and a deluge of mis-information. Events such as formula I, supported by private players, should be welcomed in India. No two ways about it. It is a biggest brand building exercises we can undertake. But the harm is not as much in hosting such events, but in what surrounds it. By utterly disregarding public sentiments and convinience, when such events are organized, and we see a breakdown of already lacking basic infrastructure and sanitation, whom should we run to?. When they out forward demand  that the sport should be granted tax exemption because of the high costs and the consequent lack of viability of the investment, then shouldn't it  need a closer inspection?... If in return of the lands acquired by the private from the farmers, they do not get their fair share, whose problem is this?...and more subtle and farreaching...a sudden and unnatural shift in the lifestyle of the farmers due to acquisition of wealth as part of land compensation leaving them unprepared for this change and thus begetting social problems....

We cannot create Brand India by creating a hype about an event. This is too simplistic and stupid an assumption. Equally true is we should not try to build brand India simply by window dressing an event as happened during CWG when the whole world knows what the reality is. Cause when we do that, it does more harm to our image and we end up doing the opposite. Also, while such initiatives on one hand do have the potential to change the perception about india in the world, they are also vulnerable to leave gaping holes out in the open for world to see, the all pervasive disparity in India.

We must not be too naive to simply hop into the bandwagon and join the jamboree, nor should we generate strong berating reactions about such events without recognizing the raison d'ĂȘtre for such event. Agree that these events are certainly an exciting indulgence for those who can afford to pay for it. However, they cannot simply be rejected based on an argument of social or cultural relevance to India. In India such disparities are bound to coexist. The solution is embark on initiatives which makes for a greater common good.

A War To Remember

Exactly forty years ago, a new nation was born. Connected through a continuous landmass and closely entwined with its destiny, undoubtedly, without India there would be no Bangladesh. The dream of Mohammad Jinnah of  a united Pakistan proved to be short lived. Since its creation Pakistan had been an unquiet and uneasy cohabitation of two regions seperated by Indian landmass - East pakistan  which erstwhile called east bengal (before1947) and West Pakistan with Sindh, Balochistan, Pujab and NWFP. Both regions though shared a common religion were far apart in cultural ethos and identities.This proved to be enough of a reason to create a rift in them. What more evidence that religion can not a be the sole unifying factor. For an individual's meaningful existence, there are other identities which are far more important than just a religious one.

Bangladesh's birth was painful and bloody. A concise account here says that a political turmoil had sparked from the sweeping victory of Mujibur Rahman's Party  over Zulfikar Ali bhutto in the first general election which susequently prompted Yahya Khan to suspend the election results and send army to occupy east pakistan. India was closely watching all the developments in the region and was prepared for this. What she was not prepared for was the utter brutalilty with which it was carried out.

In a single most daring Blitzkrieg operation, Indian forces launched a multi-pronged offensive involving all three services (land, water, air) first time in the history. Not only this, Indian army also trained thousands of refugees from east pakistan in the military combat techniques and formed "Mukti Bahini" which also faught the war along with them. Severely battered on both the fronts, Pakistan forces lost their ground and finally on December 16, 1971, they surrendered unconditionally.

During Bangladesh crisis Indira Gandhi showed her qualities of decisiveness. Notwithstanding her controversial years in power, this was one such decision which gave her a permamnent place in the heart of Indians. In a penetrating article here on Indira Gandhi, Sudipta Kaviraj presents a picture of global balance of power around that time. She says that global powers such as USSR, america and UK had polarised the world in two factions due to Coldwar. Here I quote from the article - Soviet attitude towards India had changed considerably after Nehru's death, and their overtures with the Ayub regime sometimes created discernible strains with India.On the American side, the Nixon administration tilted US policy heavily against India, in an accentuation of the eternal paradox of American foreign policy—its steadfast preference for an avowed dictatorship to a democracy. China too could be expected to favour Pakistan. Risks of isolation were considerable and quite real. A possible war with Pakistan and the creation of a friendly state in the east could, however, alter the strategic balance considerably, and reduce the requirement for military preparedness and related costs, at least so it was believed at the time. Here Indira in one shrewd unexpected decicion, signed a treaty with the Soviet Union which proved remarkably effective in counter-balancing American support for Pakistan.

Such remarkable assertiveness and convincing victory that established India as the dominant power in the continent, was seen for the first time (and last?? alas) in history. India learnt its biggest lesson from this glorious victory that whatever had been the power equations, countries reacted to any critical developments strictly within the boundary of their perceived self-interests and not on any moral or objective ground.

Lunar Eclipse of 2011

We recently witnessed a total Lunar Eclipse, the splendid celestial phenomenon, on 10th of dec 2011 which was second and last such event in the year 2011. The first eclipse happened on June 15, 2011. This time around the Moon had been bigger and redder. A wonder ful video from NASA explains this effect


Couple of interesting facts that I am going to share about Lunar eclispe. We all know that an eclipse has two shadowy regions, Umbra and Penumbra. It is difficult to predict the exact brightness distribution in the umbra so observers use a scale called The Danjon value for estimating brightness at different times during totality of the eclipse.The Danjon scale of Lunar Eclipse brightness was proposed by the French astronomer André-Louis Danjon and is measured on a 5 point scale from L0 to L4, where L is the luminosity.

     L = 0     Very dark eclipse.Moon almost invisible, especially at mid-totality.

     L = 1     Dark Eclipse, gray or brownish in coloration.Details distinguishable only with 
     difficulty.

     L = 2     Deep red or rust-colored eclipse.Very dark central shadow, while outer edge of
     umbra is relatively bright.

     L = 3     Brick-red eclipse.Umbral shadow usually has a bright or yellow rim.

     L = 4     Very bright copper-red or orange eclipse. Umbral shadow has a bluish, very bright
     rim.
 
At, the time of eclipse, Moon was at an altitude of 30 degrees in the constellation of Taurus and 
was placed in the midst of other recongnizable constellations such as Auriga, Orion and Pleiades.
 
Eclipses follow a certain periodicity in their occurances. Every year there are at least two lunar 
eclipses. If one knows the date and time of an eclipse, it is possible to predict the occurrence of 
other eclipses using cycle measurements such as the saros. The saros is a period of 223
synodic months (approximately 6585.3213 days, or nearly 18 years 11 days), that can be used 
to predict eclipses of the Sun and Moon. After completing a saros in an eclipse, the Sun, 
Earth, and Moon return to approximately the same relative geometric positions, and a nearly 
identical eclipse will occur in an eclipse cycle. A one half of a saros is called a sar.According to 
NASA, december 10th total lunar eclipse was the 23rd member of Saros 135, a 
series of 71 eclipses occurring in the following order: 9 penumbral, 10 partial, 23 total, 7 partial,
and 22 penumbral lunar eclipses 

Another beautiful and rare celestial effect which was seen during Lunar eclipse is called 
selenelion. This occurs when eclipsed Moon andSun are observed in the sky at the same 
time. 
 
An active member of Bangalore Astronomy club took brilliant pictures of this eclipse
from Bangalore, India

Next year in 2012, a total solar eclipse has been predicted to occur on  Nov 13th. 
More information on that later.
