Around 1400 there lived an Indian astronomer and mathematician by the name of Madhava of Saṅgamagrāma. He was the greatest mathematician of his time and, among other mathematical feats, he and his followers managed to discover a lot of calculus 200 years before Newton and Leibniz did their thing. While preparing a video about this Indian calculus it occurred to me that some of Madhava's discoveries can be used to give a nice intuitive explanation of Powell's Pi Paradox, a very counterintuitive property of the famous Leibniz formula
that Martin Powell stumbled upon in 1983. In the end, giving an introduction to Madhava's discoveries and giving that intuitive explanation is what I ended up doing in this video. ("Leibniz formula" should really be "Madhava formula"!)

The Wikipedia articles about Madhava, his school and his discoveries are excellent starting points if you are interested in more details:
My explanation of how Madhava may have discovered his correction terms is based on this article by Hayashi, T., T. Kusuba, and M. Yano. "The Correction of the Madhava Series for the Circumference of a Circle." Centaurus 33 (1990): 149-174. This article is sitting behind a paywall. However, the wiki article linked to above is a good summary.
The original article by Powell in which he reports on his observation and asks for an explanation is here: www.jstor.org/stable/3616550
Five explanations were subsequently given in this article published in the same math journal: www.jstor.org/stable/3617175 (note on JSTOR this collection of articles is broken up into four parts. This link is only to the first part).
The most in-depth article about the Powell's Pi Paradox is this one here by the Borwein brothers and K. Dilcher on "Pi, Euler Numbers, and Asymptotic Expansions": www.maa.org/sites/default/fil...
In this article they also analyse similar paradoxical behaviours of closely related series like ln(2)=1-1/2+.1/3-1/4+1/5-...
The photo of that palm leaf manuscript page shown at the end of the video was sourced from the slideshow of the 2022 International Congress of Mathematicians invited lecture by K. Ramasubramanian. • Krishnamurthi Ramasubr... . Also check out his website for LOTS of information about ancient Indian mathematics. www.kramasubramanian.com/ I have no idea what it says on this palm leave page, but I trust my colleague to have shown us the right thing here :)
The picture of Madhava in the thumbnail is what Google is pushing. However, this image is not a true likeness of the actual person: commons.wikimedia.org/wiki/Fi...
A couple more links to check out:
The Discovery of the "Series Formula for π by Leibniz, Gregory and Nilakantha" by Ranjan Roy: www.jstor.org/stable/2690896 Goes into a lot of detail in terms of proofs.
Some bugs:
3:36 one of the digit difference towards the end not highlighted
14:39 In the 121 terms sums the correction terms features a minus in the place of a plus.
18:36 In the fourth correction term it should be ...N+9/(4N)

@higherbeingX 9 aylar önce
Madhava, Neelakanda, Chomathiri, etc, mathematicians belong to the 13th and 14th-century Kerala School of Mathematics. The math at that time was very advanced touching the basics of calculus and infinite series, but most were written as 'Shlokas' in Sanskrit or old malayalam. ie as poems. Kerala was the epicenter of global spice trade and it's possible that many of the original ideas were transferred to Europe which benefitted European mathematicians. Taylor series expansion and various other infinite series were discovered by Kerala mathematicians
It's possible Fermat knew of the work of the Kerala school. It's even more likely that Cavalieri did. Although there's no direct evidence, his mind seemed to run down very similar lines. But I think there's a very concrete way to show Europeans did not know the results of that work at all. It became fashionable in the 16th Century for Mathematicians to show their prowess at calculation by working out the digits of pi using Archimedes's method and polygons with ridiculous numbers of sides. If any of them had known of Madhava, then we would expect someone to make use of it or attempt to reverse engineer it, and yet, no one does so until Newton, Gregory, and Leibniz.

One correction to the above. Yuktibhasha written by Jyeshthadeva from where we know these discoveries and their proofs was written in Malayalam and not Sanskrit and in fact that is one of the reasons why these exploits of Madhava was slow to percolate (lots of Sanskrit scholars were scouring Sanskrit books because well all knowledge was supposed to have been recorded in Sanskrit missing out on other stuff)

Well, it's really like this. Because of the lack of computing power in those ancient times, it would have been very unlikely for mathematicians to observe that paradox. On the other hand, if Powell had travelled back in time and told Madhava about this paradox, Madhava would have been able to come up with the explanation in this video straightaway. Having said that, as far as I know I am the first to make the connection between Madhava's correction terms and the paradox :)

To be fair, the lack of recognition of the ancient Indian and Chinese mathematicians' work is probably not all because of a Western colonial mentality or sense of superiority, although that undoubtedly plays a role as well, don't get me wrong. However, I think it's also simply the result of a cultural and linguistic barrier. In their time, Western scholars like Leibniz and Gregory had little chance of even looking at a medieval Indian manuscript within their lifetime. But even if they could, hardly anyone in Europe would have been capable of reading it, yet alone realising that it contains a mathematical discovery that predated their own by two hundred years.

Its really sad how conquest and colonialism affect scientific progess. India went from one of the few bright spots in the scientific world to a mediocre country after centuries of destruction. Not to mention the texts that were literally destroyed during invasions. Its scary to think how much knowledge humanity has lost just because of wars and plundering.

Previously the article stated that it was not clear how Madhava had found the three correction terms in polynomial form he had provided. They happened to be the first three approximants of that continued fraction. I have found the pattern of the continued fraction numerically, using pi to 34 digits rather than the few given by 355/113. (Edited to fix a couple of typos)

I have come up with a third continued-fraction that works as a correction factor for the Wallis Product, which unlike the previous ones appear to be something really new. In the WolframAlpha notation the complete expression can be written as “ Product((4k^2)/(4k^2 - 1),{k,1,n})*(2 + 4/(8n + 3 + ContinuedFractionK[4k^2 - 1,8n +4,{k,1,n}])) ” This produces 25n/12 correct decimals of pi, however a proof is still missing.

Past scientist would have been happy and proud of us seeing the collaboration and joy.

Kindly search for more Mathematicians like Bhaskaracharya and you'll be amazed to discover most of the discoveries of Maths as modern world know of ... Thanks once Again sir
For more than 1000 years India was under foreign rule. You can imagine how much cultural, economic, scientific, literature etc damage had happened. So much so that Indians themselves don't believe such geniuses were their ancestors. Thank you so much for showing the world about Madhava. There are so many other people who require special attention and mention. The world will only benefit by this exploration.

I've read about or seen videos about this extremely-slowly converging series for Pi (or for Pi/4) many times. Why did the idea of an error correction term never occur to me? This is brilliant, and it's amazing that this mathematician figured this out in the 1400s!

@anujmishra4412 9 aylar önce
Thanks a lot, Mathaloger! I have studied some works of Madhava but didn't know about these beautiful correction terms. Our textbooks in India still reflect a post-colonial mindset, resulting in a significant lack of awareness and ignorance. Unfortunately, many important contributions from Indian scholars are overlooked or not adequately highlighted. For instance, Baudhayana, who authored the world's first geometry textbook, including the Pythagorean theorem long before Pythagoras, is rarely mentioned. Similarly, Pingala's profound insights into permutations and combinations within the context of literature are often disregarded, despite their beauty and significance. Aryabhata's foundational work in trigonometry, which forms the basis of our modern understanding, also receives insufficient attention. Furthermore, there's no mention of Madhava, or any mathematician from the Nila school, in our great textbooks. They only perpetuate a subtle sense of inferiority complex by failing to acknowledge these remarkable achievements. It is high time for a change in our educational curriculum. One aspect I particularly admire is India's significant contributions to philosophy and spirituality. These traditions are not only highly logical but also explore the limitations of logic itself, as evident in the concept of non-dualism. Additionally, architectural marvels like the Kailash temple exemplify India's profound knowledge in the field of architecture. Regrettably, we have lost a great deal of knowledge due to constant invasions, including the destruction of the precious Nalanda University, the world's first residential university. There is so much more to be said about India's marvelous contributions to the world. It is my hope that our generation recognizes and appreciates the immense legacy left by our ancestors. Thank you so much again. Keep up the amazing work that you do!!

This is the reason I love to read and learn about Indian History, but the problem is that, in my achool, classes, college, I was the only one who loved history ... Other people are of the opinion that history is boring and cannot help us in any way, but we say na "bandar kya jaane adrakh ka swaad !"😄 I really think everyone should learn Indian History it is really interesting and never fails to make us proud of what India was before colonization!

@amkamath 9 aylar önce
Such a lovely insight! This explains the error term in any base, but certainly easier to notice in base 10. I wonder if Madhava also considered series for Pi based on the series expansion for arctan(1/sqrt(3)) = Pi/6, which converges faster. It is hard to imagine how they discovered these results without using our present day notation.
@Mathologer 9 aylar önce

Far from taking away from Newton's and Leibniz's achievements, who surely were unaware of their distant predecessors, it's an astonishing testament to the wonderful unity and universality of mathematics; one of the few human exploits in which all cultures have contributed equally. Historians of mathematics, we want to hear more from you, and louder!
