The Vedas are timeless. Indic scholars do not ascribe a particular time to its origin because it has always "been there" - the Vedas are considered to be a constantly evolving treasure of knowledge, wisdom, science, math, and 'best practices' since time immemorial. Modern researchers' requirement to assign a measurable date to an event and slot it into their finite history model results in a 'start date' for some random snapshot of the Vedas that is anywhere between 2-5K years prior to the common era.
The Vedas are in Sanskrit
The Vedas contains a wealth of useful guidelines and ethical principles to ensure a productive lifestyle that is in harmony with the surroundings. Indeed, the word as well as the religion 'Hinduism' that is in use today is an inaccurate artifact created by colonizing Europeans (update, 2013: Term 'Hindu' is much more ancient). The correct term is Sanathana Dharma, a phrase that very roughly translates as "the right way for good guys (and gals) to lead their life". There is no equivalent for Dharma in English, and there is no word for organized religion in Sanskrit to the best of my knowledge (update, 2013: highly limited knowledge).
Fidelity of the Vedas
From an algorithmic and modeling perspective, an amazing fact is that the Vedas have been orally transmitted and remembered using Vedic Chants across millennia, and what we hear today is probably what was first chanted a very, very, long time ago. In a world that is so accustomed to written proof, this approach and it's implications can be a bit tough to grasp initially.
Vedic Chants and its Impact
Per Wikipedia "The UNESCO proclaimed the tradition of Vedic chant a Masterpiece of the Oral and Intangible Heritage of Humanity on November 7, 2003." The Vedas are to be listened to, and not primarily intended to be a reading text. The textual meaning of the Sanskrit words in the Vedas are but a part of its benefit, but the way it is combined together and chanted in a specific manner is equally if not more important. It is this entire structure that has been remarkably preserved across eras and onslaughts including Greek, Mongolian, Central Asian, and European invaders. There were no "heretic" writings for them to easily destroy and thanks to these error codes, India has been able to maintain an unbroken chain of culture and thus retain the most ancient of its connections to its roots.
Here's a digital sample of a Vedic chant. Some may notice a passing resemblance to mystic pagan, Gaelic, or Gregorian Latin chants.
I'm betting those wise old Rishis (Indian sages) would have dug OR for its practicality, so they sure would have loved to chant:
"operations research is the science and engineering of better". We'll drop the 'engineering' part for the sake of brevity.
The meaning and pronunciation of each Sanskrit word stands unambiguously by itself and is written just like it sounds (unlike, say English). Sanskrit is characterized by precision. It requires no punctuation marks. Orally, this is accomplished by chanting each word in the passage distinctly, one after the other (a "/" indicates a brief pause).
Code 1: operations/research/is/the/science/of/better
However, even a few hundred cycles is likely to induce errors (In English: where's the comma, pause, syllable emphasis, etc), so they must have decided to add a second layer that chains a word to the next one:
Code 2: operations research/research is/is the/the science/science of/of better
Each word is now spoken twice in order, thereby introducing some redundancy, while also explaining how pairs of words are to be spoken in combination. Remember, the pitch and tone for a particular word may depend on one or more words that precede or follow any given word. Sure enough, another Rishi decided to take this a step further by chaining three words to introduce further redundancy and handle cases where the ebbs and flows in the chants persist a bit longer.
Yet another Rishi put words together in an apparently strange way to create:
Braid Code: operations research research operations operations research/research is is research research is /is the the is is the/the science science the the science/science of of science science of/of better better of of better
The number of times a particular word is repeated is 6. The phrases seem to be chanted in a forward/reverse/ forward format. However, this is a moot point in Sanskrit because switching the order of the words in a sentence does not change the meaning! In other words, each section in Code 2 is chanted thrice in different orders, but they reinforce the exact same meaning each time. Indeed, this also ensures that Rishis who loved to swap words around could now do so (even inadvertently) without fear of messing up the cadence. Pretty cool. Those who've followed this tab for a while would have noticed that the words in this tab are often hopelessly out of order. It's not easy to downgrade to English and write acceptable OR journal papers :)
There are a few more codes, but the pièce de résistance is this particular "bell code" which also happens to be the most pleasing to the ear:
Bell code: operations research research operations operations research is is research operations operations research is/
research is is research research is the the is research research is the/
is the the is is the science science the is is the science/
the science science the the science of of science the the science of/... and so on
The number of times a particular word is spoken in this code is 10, i.e. a factor of 10 redundancy. A sample of the Bell-code chant (the example chosen is the "peace mantra") can be found toward the bottom of this site. Search for the phrase "Ghana Paatha". The first 2.5 minutes is the same mantra that was chanted in the first example, but is now done by a different individual. Comparing the variations in the two performances gives us an idea of the challenge faced by those Rishis eons ago.
If the order of words doesn't matter, there's going to be an exponential number of ways of speaking a sentence correctly without altering the meaning (although some choices are more preferable and popular). But this also serves as a natural fault-tolerant mechanism. Each ordering is an alternative feasible solution that results in at least the correct decoding of the meaning of the passage; yet another reason why the treasures of the Vedas would have been lost to the world without the magical medium of Sanskrit. The Rishis appear to have managed these permutations by carefully designing the chants in sync with phrases to make it easier to orally encode and decode a massive amount of information across generations without a single written note. Indeed, they may have thought of this as an infinite horizon problem given the cyclical time concept of Indian philosophy. They appear to have converged on a limited number of simple encoding rules that appear to be quite effective as well as practically robust. It is estimated that it would take a month or two of continuous chanting to cover the entire bell-code version of the Vedas!
We know that there's an inherent connection between linguistics and computer science. If Jeopardy were to be played in Sanskrit, would IBM's Watson have been more accurate and less dependent on guesswork?
These ideas also seem to be used in reinforcing learning among kids. Songs and rhymes with repetitive themes appear to be relatively easier to remember over long time periods. The holiday song in the previous post is a good example. If we ever wondered what drives otherwise fun-loving Indian kids to memorize entire lexicons to collect endless Spelling Bee trophies, and why there is so much emphasis on rote learning in India, now we know its because of Shruti and her dual, Smriti.
It would be nice if our business customers were to present all their business rules, priorities, and goals in bell-code Sanskrit verse on a CD rather than Word text and Power-point charts to avoid the endless headaches arising from the inevitable losses in translation!
