Fields Medal Winner Manjul Bhargava On the Pythagorean Theorem Controversy

prajendran writes There were a lot of controversies generated at the Indian Science Congress earlier this month, including claims of ancient aircraft in India, the use of plastic surgery there, and ways to divine underground water sources using herbal paste on the feet. One argument that could be tested using some form of evidence was the assertion by Science Minister Harsh Vardhan that the Pythagorean theorem was discovered in India. Manjul Bhargava, a Princeton University professor of mathematics and a Fields Medal winner describes why the question is not defined well.

      (**) I'm talking of course of the logical structure, not the actual geometrical results.

This is how future generations of mathematicians are able to completely assimilate, and then surpass, in a very short time, the discoveries of their teachers.

      The only good point he made is that by mathematical standards the question is who proved the theorem.

      I disagree. Proofs aren't the only important element of mathematical creation/discovery. Conjectures are also crucial, and there are lots of important conjectures which are notable long before they're proved. The Pythagorean theorem is clearly one such, because it's extremely useful even if you can't prove it. For that matter, as noted by the article, the Egyptians found it very useful, and they not only didn't have a proof, they didn't even fully understand the relation. They merely knew that some certain combinations of proportions made right triangles... and then used that fact all over the place. The Babylonians also probably understood the principle, and the Pythagoreans likely learned it from them or the Egyptians.

      In addition, even a proof is irrelevant if it just gets lost, or buried. Communication of proofs, especially as part of a systematic theory is even more important and -- as you correctly noted -- that achievement is indisputably Greek. How much of it was due to the Pythagorean mystics and how much to Euclid is a matter of much debate; some historians of mathematics argue that the Pythagoreans discovered essentially everything in the first two books of Elements. Euclid's main achievement with respect to the theorem may well have been mostly just to record it and remove all of the references to beans and the rest of the Pythagorean mysticism. What the truth is we'll likely never know, but the Greeks attributed the knowledge of the theorem to Pythagoras, which I think is quite meaningful.

      All of these stages in the development, proof, formalization and dissemination of important ideas are crucial. The best point to be made here is that the question is inherently meaningless. Any attempt to pick an "origin" must fail because the theorem originated over millenia, and was likely independently discovered in different regions at different times. Even if it's a Chinese manuscript that contains the earliest proof, it seems unlikely that the Greeks got it from the Chinese, and it appears that the Chinese proof in question had little effect on history, Eastern or Western, while the Greek proof, alongside the rest of Elements, fundamentally shaped Western civilization.

      That last claim may seem a little too strong, but it's not. Greek Mathematics didn't so much influence Greek philosophy as create it, and Greek philosophy similarly founded Western philosophy as a whole.

      Plato's philosophy in particular, was essentially mathematical, and his notion of Forms, the central element of his ideas, is clearly an attempt to relate the pure, abstract beauty of geometry to the world as a whole, and to use it as a vehicle for understanding reality and man's relationship with it. Aristotle was, in many ways, the anti-Plato, but he also deeply honored mathematics. All of the rest of Western philosophy, including its deep influence on social and political structures, can be viewed, as Russell said, as a series of footnotes to Plato and Aristotle, they were that important. And a large part of the powerful influence of Greek ideas on Roman, medieval Christian, Renaissance and modern philosophy derived from the elegance and power of Greek mathematics. Although it wasn't often stated so clearly, the indisputable clarity and power of Greek mathematics impressed later generations and convinced them that the rest of Greek wisdom might well be equally profound.

      The Pythagorean version, as presented by Euclid, mattered.

      There may have been a half-dozen proofs of the Pythagorean theorem created, recorded and lost, in many locations around the world, perhaps long before Pythagoras. But none of them mattered. The one that did is the Greek proof, and the Greeks credited the Pythagoreans.

    There is really no doubt that ancient India (even starting around 2500 BC or earlier) had made a lot of discoveries and technology advances. The same is true of ancient China. Don't forget that over 4000 years have elapsed so, naturally, a lot of information will have been lost along the way. The state of our world today owes a lot to these ancient civilizations, along with others such as Egyptians etc.

    We should also recognize that today's world is Greek-Roman-centric, believing that logical thought, technology etc. originated with them. That is what most of us are taught in elementary/high-school in N. America and Europe. So, obviously that is what we believe. While the Greeks/Romans did come up with a lot of original thought and discoveries they were not the first in everything they are credited with. Many of their "original" ideas were already over a 1000 years or more older having been developed in either China or India. Do a little research and you will find that there were highly developed civilizations in the Indian sub-continent and China.

    How exactly did they get to be so advanced if they did not have advanced tools / technology / thinking etc. ? And all this many 1000's of years before the Greeks/Romans ?

    One needs to also understand that the West (Europe / N. America) is the power center of the world currently. This further's the status-quo of what we are taught. However, just a little research & Googling will demonstrate that not everything we are taught is correct or the truth.

    So, here is a bit of background on how we reached this state:
    It has a huge amount to do with 200 years of British rule of India, who, during that time, came up with systematic methods at wiping out indigenous technology/ processes / knowledge / thought, to attempt at establishing the superiority of European (not American) thought & techniques during their occupation from the 1700's up to mid 1940's. It all boils down at trying to break the psyche & spirit of the people for obvious goals (to rule over them etc.). They had to do this because when they originally arrived on the Indian subcontinent they found a fairly advanced civilization. So, now they needed a method to convince their population back home that the "locals" were in need of "civilizing". They did such a good job that many Indian leaders of the late 1800's / 1900's actually started believing in the inferiority of Indian thought (and superiority of Europeans). Naturally, these leaders had a knock-on effect on the population. To an extent the British did a pretty thorough job at killing indigenous technology/medicine etc.

    Additionally, on the religious side, in the 1800's / early 1900's there was a lot of revisionist history being written. Anything that did not fall in line with Christian dates "could not have happened". This resulted in dates in a lot of ancient Indian texts being re-written to suit the views of other people. A good example is the Aryan Invasion Theory and other ideas propagated by Karl Marx. The Indian's were then taught (by Europeans) that they did not understand their own history and were given the newly "revised" history. These history books continue to have influence today.

    Everything stated above can easily be verified via some simple Google searches so I am not listing specific references.

    7) Cut the string at the fold
    8) Adjust the 4 lengths such that the cut string stretches from one corner to the opposite corner.

    Congratulations, you have a square marked out for your building.

    If you can measure angles, it's even easier, and you *still* don't need the PT.
    You need:
    A) Four equal lengths of whatever you're going to use to mark where to put the walls of the building.
    B) A sufficiently long length of string.
    To make a square:
    1) Lay out the 4 lengths, end to end, so that they form a closed loop.
    2) Measure one angle
    3) Adjust until that angle is 90 degrees.

    Congratulations you have a square.

    Note: These instructions assume your marking lengths (A) are rigid. If they are not (such as being made of string themselves), it's a *bit* trickier, because you have to keep the lengths taught, but the process is fundamentally the same.

    I, too, am very proud of how the first single cell organisms survived to become multicellular. You go, Eoarchean awesome cells! At some point, don't we just have to call history the past and move on to create our own future??? If we humans want to continue to survive, we are going to have to start thinking much more about the future, and dwelling less on attributions of the past. Don't get me wrong, it is good to know what happened and learn from it. But, once you find your historical sources have run out and you are basing your conclusions on millionth hand anecdotal evidence, it is time to let the past be the past.

    You have to invent mathematics. It isn't a feature of the real world.

    Consider Euclid, for example. He has postulates, axioms, and definitions, and proceeds to deduce interesting things from these. He made things up: he knew of no physical examples of points or lines or circles, just approximations. He looked at real-life dots and almost-straight lines and almost-perfect circles, abstracted them, and ran with it.

    At that time, it was thought that geometry (earth-measure) was a description of reality, just like arithmetic. Many philosophers set themselves a goal of proving things about the world in a similar manner. Eventually, we figured out that we could invent other geometries, and much later that pretty much everything interesting has non-Euclidean geometries.
