The Gupta Empire reaches its scientific zenith as we meet one of the greatest mathematicians of Late Antiquity.

Aryabhata (476–550 CE) helped transform astronomy and mathematics in India through a remarkable combination of elegant algorithms and practical computation. In this episode we explore his Aryabhatiya, from recursive square and cube root algorithms to the famous Kuttaka ("Pulveriser") method for solving indeterminate equations. Along the way we investigate his astonishingly accurate value of π, some of the earliest trigonometric tables, numerical methods that hint at calculus over a thousand years before Newton, and his important role in the long, collective story of the invention of zero.

We also take a tour through the Gupta Empire, discuss why astronomy drove so much mathematical innovation, and ask whether Aryabhata deserves his reputation as one of history's greatest mathematicians.

As always, there are terrible puns, historical tangents, and probably more discussion of Huns than anyone expected.

The Silk Road carried spices, gemstones, ideas... and, occasionally, trigonometry.

In this episode of The Mathematicians Podcast, we follow the mysterious figure known as Yavanesvara, the "Lord of the Greeks," whose translation of Greek astronomical and astrological knowledge into Sanskrit helped spark a mathematical transformation in ancient India.

Along the way, we explore merchant trade across the Indian Ocean, the origins of sine tables, spherical astronomy, navigation, observational error, and the surprisingly rich mathematics hidden inside astrology. We also take a brief detour through gem shops, Roman trade deficits, and the everyday mathematics of merchants using techniques such as double false position and casting out nines.

History remembers Yavanesvara only dimly, but the mathematical journey he represents would help bridge the gap between the early Indian traditions and the age of Aryabhata.

Because sometimes the most important travellers don't carry goods; they carry ideas.

Why is a 2nd-century BCE Indian grammarian being featured on a mathematics podcast? Because centuries before the "Founding Fathers" of Western mathematics were born, Pingala was already encoding the universe.

In this special rhythmic episode, I step out of the traditional lecture hall and into the world of spoken word. After a transformative experience at the 'Beat up the Poets' conference, I will explore the Chandaḥśāstra; Pingala’s ancient treatise on prosody.

We look into how the study of Sanskrit poetic meters led to the earliest known descriptions of:

• Binary Number Systems: How stressed and unstressed syllables created a mathematical logic long before Turing.

• The Concept of Zero (Shunya): The "original gap" in the poetic flow.

• The Fibonacci Sequence: Why the "Man from Pisa" was actually a few centuries late to the party.

• Pascal’s Triangle: Uncovering the "Meru Prastāra" hidden in ancient Vedic verses.

From "off-by-one" errors to the combinatorics of rhythmic beats, this episode is a lyrical journey into the seismic foundations of ancient Indian mathematics.

Note from me:This is my final pre-recorded episode before I head off on paternity leave! Thank you all for your incredible support. I’ll be taking a short writing break to welcome the new addition to the family, but the podcast will return soon.

In this special book club episode of 'The Mathematicians Podcast', I sit down with author, maths communicator, and museum learning consultant, Thomas K. Briggs. Join us for a glass of wine and a deep dive into Tom's book, 'The Mathematicians Library', a title so intriguing it was a must-have for the show.

This 'Injectives' sub-series episode is a one-to-one conversation; today exploring the vast history of mathematical literature. Discover the oldest book in Tom's personal collection and unravel the criteria for what truly constitutes a "book of mathematics". Tom paints a vivid picture of ancient mathematical works, describing the evolution of writing media before the age of flat sheets and ink.

The discussion navigates through the emergence of authorship in the Mediterranean, Indian, and Chinese traditions, and Tom shares his favourite example of a significant mathematical work without a known author. He also recounts the fascinating journey of a particular mathematical text through the ages, a story of translation and transcription that has preserved ancient knowledge.

In a new segment of "Desert Island Codex," Tom reveals which ancient mathematical document he would choose to study in solitude and which ancient lecture he would love to have heard.

Moving beyond the book, the episode looks into Tom's work as a museum consultant. He sheds light on the origins of encryption and the methods ancient leaders used to send secret messages. The discussion also explores the vast, untranslated collection of Babylonian tablets and what they might still reveal about Mesopotamian mathematical understanding.

Finally, Tom offers his own insightful, pithy definition of what mathematics truly is. He also reveals which mathematician he is most excited to see featured on a future episode of the podcast.

Tune in for a captivating conversation that journeys through the annals of mathematical history, from ancient texts to modern museum exhibits.

In this episode of The Mathematicians Podcast, I am jumping ahead 800 years and travelling 5,000 km back to India to pick up the threads of a fascinating mathematical tradition. I’ll be introducing you to Umaswati, a pivotal figure from around the 2nd Century CE who helped systematise the teachings of Jainism, a religion where "Right Knowledge" and the study of the cosmos made maths a fundamental pursuit.

Together, we explore the four broad periods of Indian religious development: Vedic, Śhramana, Puranic, and Bhakti, and see how the Jain tradition carved out a unique space for mathematical inquiry. We’ll discuss:

• The approximation of \pi : Why the Jains used \sqrt{10} and how they handled circular segments.

• The power of place value: How ancient Indian poets and scholars were comfortably using numbers as large as 10^64 while the Greeks were still stuck at the Myriad

• The Five Types of Infinity: Long before Georg Cantor revolutionised set theory in the 19th century, Umaswati and the Jain scholars were already classifying different scales of the infinite and the transfinite.

Join me as I navigate the intersection of faith, philosophy, and the infinite.

When is an approximation "good enough"? This week on The Mathematicians Podcast, host Benjamin Cornish opens the doors to his gem and fossil shop to discuss why a polished piece of glass, or a clever mathematical shortcut, can sometimes be just as effective as the real thing.

We are shifting our focus toward the sprawling, shifting history of Mesopotamia. Today, we tackle a double bill of Babylonian titans: Nabu-rimanni and Kidinu. Though separated by two centuries and a revolving door of empires (from the Persians to the Greeks), these two temple astronomers foresaw the blossoming of predictive science.

In this episode, we explore:

• The "Feet of Clay" History: A whirlwind tour of Babylon, from the Tower of Babel and Hammurabi’s Code to the rise of the Persians and the lightning conquest of Alexander the Great.

• System A vs. System B: How Nabu-rimanni’s constant velocity model evolved into Kidinu’s sophisticated "zigzag" acceleration system.

• The Two-Second Error: How ancient mathematicians using little more than water clocks calculated the synodic month with a precision that rivals modern satellite data.

• The Babylonian Legacy: Why the Greeks (including Hipparchus) owe their greatest discoveries to the meticulous clay tablets of the East.

Episode 52 of The Mathematicians Podcast, takes us deep into the world of ancient Indian mathematics with a focus on Apastamba and his contributions to the Sulvasutras. Following in the footsteps of Baudhayana, Apastamba codified and clarified Vedic ritual geometry, transforming abstract rules into practical, modular construction techniques. We explore his mathematical approach, the subtle differences between his Sulvasutras and those of Baudhayana, and his work on the Dharma Sutra, which laid out ethical and social laws with remarkable precision.

In this episode a journey back to 800 BCE to explore the life and work of Baudhayana, one of the earliest known mathematicians from the Indian tradition.

This episode also offers context on the Vedic tradition, the role of mathematics in ritual practices, and the broader connections between ethical, social, and technical knowledge. We discuss how mathematics was a practical, problem-solving craft in ancient India, designed to be memorized, teachable, and repeatable, an engineering mindset long before modern formalizations. Listeners will gain a rich understanding of the spiritual, cultural, and mathematical landscape in which Baudhayana worked, and why his contributions remain significant today.

Finally, the episode touches on questions of historical credit, colonial narratives in mathematics, and how we name mathematical discoveries, challenging us to reconsider what we think we “know” about the history of ideas.
