The Library of Alexandria: What Really Happened?

Shownotes
After nearly seven years and more than 200 episodes, this is where I say goodbye to Math! Science! History!. The podcast began with my book Hypatia: The Sum of Her Life and grew into something far beyond what I imagined. Thank you for listening, for following me through all of these stories, and for giving me the opportunity to explore the history behind mathematics, science, and the people and ideas that changed our understanding of the world. The podcast may be ending, but the archive, the research, and the stories will remain here for you to explore.
And perhaps it's fitting that our final story is about the Library of Alexandria. The Library didn't survive as an institution, but its ideas survived because people copied them, studied them, translated them, and passed them on. I hope Math! Science! History! can do something similar. As I move into whatever comes next, I'll leave you with the original meaning of carpe diem: to pluck the day, to savor what is ripe and ready, and then use that harvest to plant the seeds for the next season. Thank you for seven incredible years. Carpe diem, my friends.
3 Things You'll Learn
1. The Library of Alexandria was not necessarily destroyed by Caesar. Caesar's fire in 48 BCE certainly destroyed books, but the ancient evidence does not establish that it destroyed the entire Library. Alexandria's scholarly institutions and collections continued afterward.
2. The Library disappeared through a much longer and more complicated process. The Royal Library, Mouseion, Serapeum, and other collections existed in different forms and at different times. Political instability, changing patronage, violence, destruction, and institutional decline all played roles in the gradual disappearance of Alexandria's great scholarly institutions.
3. Knowledge can survive even when institutions disappear. The books of Alexandria did not remain together as one intact collection, but ideas survived through copying, translation, and transmission. Centuries later, scholars working across the Byzantine, Syriac, Persian, and Islamic worlds helped preserve and transmit Greek knowledge into Arabic and beyond.

Shownotes
René Descartes is famous for Cogito, ergo sum and his revolutionary approach to philosophy and mathematics. But he also left behind a mysterious 16-page manuscript written in code.
In this episode, we uncover the story of Descartes' hidden notebook, the waterlogged manuscripts that nearly disappeared, and Gottfried Wilhelm Leibniz's dramatic attempt to decipher the coded pages.
At the center of the mystery is a mathematical relationship involving the vertices, edges, and faces of three-dimensional shapes. Today expressed as V − E + F = 2, this relationship became associated with Leonhard Euler and is closely connected to the development of topology.
We'll explore why this mathematics mattered in the seventeenth century, why Descartes may have feared revealing his ideas, and how the mathematics of shapes and connectivity eventually became relevant to our modern digital world.
3 Things You'll Learn
1. Why Descartes wrote in code The story behind Cogitata Privata, Descartes' "I proceed masked" philosophy, and the secret manuscript that disappeared after Leibniz examined it.
2. How V − E + F = 2 works Using cubes and pyramids, we'll see how vertices, edges, and faces combine to produce a remarkably consistent mathematical relationship.
3. Why this old mathematics still matters The episode connects the history of polyhedra to topology and modern applications such as 3D computer graphics and digital modeling.

Shownotes
Scientists have officially identified a new wild cat species in Bolivia and a new snake species from New Guinea—and one of them is named after Guns N' Roses guitarist Slash. But these discoveries are about much more than a cute cat and a rock-star snake.
In this episode of How Did We Get Here? Science News Tuesday, we look at how scientists identify new species, why some animals can remain hidden in plain sight for centuries, and how modern genetics and genomics are changing our understanding of the tree of life.
From Carl Linnaeus and the origins of scientific classification to DNA analysis and museum specimens, we explore how scientists went from naming what they could see to uncovering evolutionary relationships that aren't visible to the naked eye.
And there's a bigger question: How many species are still out there waiting to be recognized—and could some disappear before we even know they exist?
Three Things You'll Learn
1. How a "new" species can hide in plain sight.
2. Why a snake was named after Slash, and how Slash rocks out for animals!
3. How DNA changed the way we classify life
4. Why discovering species matters for conservation
Welcome to the jungle: newly-discovered snake named after Slash from Guns N' Roses - Field Museum

Shownotes
GH Hardy was a character. He had qualities that were odd, yet endearing. He was a rigorous mathematician. Yet, when he received a letter from Srinivasa Ramanujan, he changed. He learned a new way of equating mathematics, and developed a deep and loving respect for an individual who was never formally educated in math.
This is the story of a man who had the ability to see genius in another person, even when that person couldn't see it in themselves.

Shownotes
What happens when women gather?
Throughout the eighteenth century, women across Europe began creating intellectual communities where they could discuss science, mathematics, philosophy, politics, literature, and medicine. During the Enlightenment, these gatherings helped women challenge the idea that intellectual discovery belonged exclusively to men.
Women such as Laura Bassi, Maria Gaetana Agnesi, Émilie du Châtelet, Catharine Macaulay, Caroline Herschel, and many others built on one another's work and created a path for future generations of women in science.
And that path matters far beyond science. When women gather, exchange knowledge, encourage one another, and make room for the next woman, they can change science, politics, education, and society.

Shownotes
Your job is what you do, not who you are - and that distinction could change your life. Gabrielle Birchak spotlights the astonishing story of Paul Tannery, a daytime engineer in the French tobacco administration whose after-hours curiosity helped reshape the history of mathematics and science.If you've ever felt like your work has started to define your entire identity, this episode offers a powerful reset. Gabrielle makes the case for building a second life around curiosity, hobby, and learning - not as a luxury, but as a source of well-being, purpose, and even legacy.You'll discover:
· Why meaningful interests outside work are linked to lower stress and higher life satisfaction
· How hobbies and non-work activities can strengthen mental health across cultures
· Why curiosity matters even when it never becomes "productive"
· The surprising power of sharing what you learn with other people
· A simple 20-minute weekly practice to become more than your job title
Gabrielle connects Tannery's life to modern research, including findings on psychological detachment from work and global studies on hobby engagement and mental well-being. The result is a short episode with a big message: the things you pursue for joy may end up shaping your life more than the work that pays the bills. Perfect for anyone feeling stuck in their role, hungry for a fuller identity, or looking for permission to follow their curiosity again. If you need a reminder that learning for its own sake still matters, this one will leave you thinking differently about your time, your talents, and your future.
Notable Quotes· "Your job is what you do, but it does not have to be who you are."
· "Curiosity is not a distraction from life. It is one of the things that makes life richer."
· "Knowledge grows when it is shared."

Shownotes
Paul Tannery didn't begin his career intending to become one of the most influential historians of mathematics. He trained as an engineer at the École Polytechnique and spent much of his professional life working in France's state tobacco administration. But after work, Tannery pursued a very different passion: ancient mathematics, astronomy, philosophy, and the history of science.
What began as an intellectual interest became a lifetime of scholarship.
3 TAKEAWAYS:1. How Paul Tannery transformed a personal passion into groundbreaking scholarship 2. Why Tannery believed historical claims needed evidence, not repetition 3. Why your "side interest" may matter more than you realize

Shownotes
I'm revisiting one of my first episodes: the story of John Dalton, the self-taught Quaker schoolteacher who never attended university yet gave modern atomic theory its first real momentum. Barred from English universities for his faith, Dalton turned stubborn curiosity into world-changing science, mapping colorblindness before anyone understood it and sketching the first table of elements in a notebook. This is how one weaver's son carried science from a Cumberland village to the Large Hadron Collider.
You'll learn:
• How a Quaker weaver's son barred from university built the foundation of atomic theory
• The stockings mix-up that led Dalton to discover, and later name, colorblindness
• Why his five-element notebook sketch from 1803 still echoes inside the Large Hadron Collider

For Pride Month, I profile eight scientists across eight identities in the 2SLGBTQI+ community. From the equations underpinning modern physics to the brain cells once dismissed as filler tissue, these researchers shaped the world we live in, often while hiding, fighting for, or paying dearly for who they were. Today I trace the lives of Sofia Kovalevskaya, Alan Turing, Margaret Mead, Ben Barres, Christopher Strachey, Magnus Hirschfeld, Paul Erdős, and Lozen, eight stories of brilliance that history tried, and failed, to erase.
3 Things You'll Learn in This Episode- How a forged marriage opened the door to modern physics. Sofia Kovalevskaya couldn't attend university as a woman in Russia, so she found another way in, and ended up proving foundational theorems that every engineer and physicist still relies on today.
- Why the man who helped win WWII was punished by the country he saved. Alan Turing's codebreaking work is credited with shortening the war by years and saving millions of lives. Decades later, that same government prosecuted him for being gay, then put him on its currency.
- How "supporting" brain cells turned out to be running the show. Ben Barres's research overturned decades of neuroscience consensus about glial cells, and his own experience transitioning gave him a firsthand look at gender bias in science that became one of the most cited accounts of its kind.

Shownotes
What if the negotiation strategies, workplace rhythms, and relationship instincts you've relied on your whole life already had names in mathematics? In today's FLASHCARDS! episode of Math! Science! History!, I break down three foundational concepts from game theory: dominant strategy, tit for tat, and Nash equilibrium, and connect each one to the everyday decisions, compromises, and unspoken social contracts you navigate all the time. Whether you're a math enthusiast or someone who swore they "weren't a math person," this episode reveals that you've been doing game theory your entire life without even knowing it.
🃏 In This Episode, You Will Learn:- What a dominant strategy is and how to recognize when you're already using one, from sending that follow-up email to ordering your favorite dish at a restaurant.
- The fascinating history of tit for tat, the surprisingly simple strategy that beat out complex algorithms in Robert Axelrod's famous 1980s tournament, and how it mirrors the unspoken rules of your closest relationships.
- How a Nash equilibrium shows up in everyday conflict, and why the moment you and someone else silently agree to "stop pushing" is actually a mathematically stable outcome.
📚 Sources
- Von Neumann's 1928 minimax theorem is widely considered the founding document of modern game theory. https://en.wikipedia.org/wiki/Minimax_theorem
- John Nash received the Nobel Prize in Economic Sciences in 1994 for his pioneering analysis of equilibria in the theory of non-cooperative games. https://www.nobelprize.org/prizes/economic-sciences/1994/nash/facts
- Robert Axelrod's landmark book The Evolution of Cooperation (1984) explored how cooperation can emerge among self-interested agents, using his famous computer tournament in which tit for tat won. https://en.wikipedia.org/wiki/The_Evolution_of_Cooperation

In this episode of Momentum Monday, I cover the unexpected power of game theory, not just for economists or chess players, but as a practical toolkit for smarter decisions in work, relationships, and personal habits. I break down three game-changing strategies: 1) Know Your "Game" (mapping players, rules, and payoffs) 2) Build Your BATNA (your secret weapon for negotiation leverage) 3) Tilt the Game in Your Favor (shaping interactions for win-win outcomes)
Whether you're negotiating a raise, handling a tough conversation, or just trying to stick to your gym routine, these tactics will help you design your environment for success. Learn more about game theory's real-world applications here and how to apply BATNA in negotiations here.
What You'll Learn:
- How to map your interactions like a game, identifying players, rules, and payoffs to make smarter decisions. (Source: Stanford Encyclopedia of Philosophy)
- Why BATNA (Best Alternative To a Negotiated Agreement) is your negotiation superpower, and how to build one. (Source: Harvard PON)
- How to shape your environment and incentives to tilt outcomes in your favor, even in everyday situations.

Shownotes
In this episode, I'm covering the fascinating origin story of game theory, the mathematical framework that explains how we make decisions when our choices depend on what others do. From the chess board to the Cold War, from traffic jams to Nobel Prizes, game theory is hiding everywhere in plain sight. I explore the brilliant, sometimes tortured minds of John von Neumann and John Nash, walk you through the elegant math of the minimax theorem and Nash equilibrium, and show you how these ideas have shaped economics, artificial intelligence, biology, and even nuclear diplomacy. Whether you're a math lover or just someone who's ever wondered why traffic jams form out of nowhere, this episode will completely change the way you see strategy, competition, and cooperation in everyday life.
What You'll Learn· The historical and mathematical context of the early 20th century that made game theory possible
· What a "game" actually means in the mathematical sense, and why it's about far more than chess or poker
· Who John von Neumann was and how his 1928 minimax theorem became the cornerstone of game theory
· How John Nash, a young Princeton doctoral student, revolutionized the field with the Nash equilibrium
· Why the Prisoner's Dilemma shows that rational individuals can end up with collectively bad outcomes

Shownotes
What happens when the person who does the most essential work never gets the credit? In this episode of Math, Science, History, I tell the story of Rosalind Franklin, the brilliant, exacting chemist whose X-ray diffraction image, Photo 51, revealed the double helix structure of DNA. From the basement of King's College London to the Nobel Prize ceremony she never attended, this episode traces how recognition fades, gets redistributed, and sometimes takes seventy years to settle. It's a story about science, yes, but also about who gets to be remembered, and why the quiet ones doing the actual work so often disappear from history before history knows it has a debt to pay.
What You'll Learn· How Rosalind Franklin used X-ray crystallography to capture Photo 51, and what she derived from that single image
· How Watson and Crick accessed Franklin's data without her knowledge, and what it meant for the published record
· Why Franklin never shared in the 1962 Nobel Prize, and the ongoing debate about what would have happened had she lived
Quote from the Episode"Rosalind Franklin knew the shape of DNA from its shadow. We know the shape of this problem from its data. The question this podcast really asks is whether knowing is enough.", Gabrielle Birchak

Shownotes
In this episode of Monday Momentum, I tackle the silent force that stalls your week before it even starts: overthinking. Drawing on groundbreaking cognitive research, including a Princeton study that found financial stress can drop mental performance by the equivalent of a 13-point IQ loss, and Bluma Zeigarnik's landmark 1927 findings on unfinished tasks, I reveal why mental drag is the hidden tax on your time, focus, and forward motion. More importantly, I shows you exactly how to break the loop: because momentum doesn't begin with perfect clarity, it begins with initiation. Even five minutes of action can be enough to shift your entire week.
🎓 THREE THINGS YOU'LL LEARN- The neuroscience of overthinking, why financial stress and mental loops can drain your brain as much as losing an entire night of sleep, and what research says about the cognitive cost of worry.
- The Zeigarnik and Ovsiankina effects, how unfinished tasks hijack your mental bandwidth, and why starting,even for just five minutes,is the most powerful thing you can do to build momentum.
- Three practical steps to stop the loop this week, how to name your thought spiral, convert worry into one visible action, and use the five-minute launch to break through avoidance and build unstoppable forward motion.

Shownotes
Taxes feel like a modern invention, tied to governments, elections, and April deadlines, but their story stretches back over five thousand years. In this episode of Math! Science! History!, Gabrielle traces the origins of taxation from ancient Mesopotamian clay tablets and Egyptian grain levies to Roman tax farmers, medieval tithes, and the birth of the modern income tax. Along the way, she explores how taxation has always been more than economics, it is a reflection of power, fairness, and the cost of belonging to a society.
What You'll Learn- How taxation began in ancient Mesopotamia as a system tied to temples and survival
- Why ancient Egypt created one of the first structured tax systems
- How Athens and Rome approached taxation very differently, and what that reveals about politics
- The role of feudalism and the church in shaping medieval taxation
- Why the Magna Carta transformed the idea of taxation and consent
- How and why the modern income tax was introduced in Britain and the United States
- The origin of tax withholding and why it changed everything
- What "top marginal tax rate" actually means (and why it matters)
- How war, especially mass conscription, drove some of the highest tax rates in history
- Why debates about "fair share" have remained unchanged for thousands of years
"Who decides what you owe, and what does it cost to belong to a society?"

In this week's Monday Momentum, I explore how mentorship creates forward motion in both your career and your life. Inspired by the Maria Gaetana Agnesi episode, I discuss how seeking guidance and giving guidance in parallel acts like a flywheel, building momentum that carries projects, learning, and personal growth forward. I share actionable tips for finding a mentor, mentoring others, and observing the momentum that emerges when support flows in both directions.
Resources & Research:
- Less than half of professionals report having a mentor, yet those with mentors are much more likely to advance and feel engaged at work (Gallup)
- Mentored employees are promoted up to five times more often, and mentors themselves can see promotions up to six times more often (Mentorloop)
- Mentorship improves job satisfaction and organizational commitment
- Organizations with mentoring programs experience higher engagement and retention (Chronus)
- Long-term mentoring correlates with higher lifetime earnings, educational attainment, and leadership development (After School Alliance)

In this episode of Flashcards Friday, I break down a powerful diagnostic framework, the Six Gates of Access, that reveals why resources like healthcare, education, legal help, and business funding can exist on paper while remaining completely out of reach for millions of women. Moving far beyond the question of whether help exists, I map each gate, Awareness, Eligibility, Friction, Capacity, Continuity, and Safety, across four real-world scenarios: maternal health, advanced education, entrepreneurship, and workplace discrimination, giving listeners a practical tool to identify exactly which barrier is blocking progress and what to do about it.
Learn about:
- The Six Gates of Access framework, a diagnostic model that explains why "a resource exists" and "a resource is reachable" are two very different things, and how any single failing gate can make an entire system inaccessible.
- How the gates show up differently depending on whether you're seeking prenatal care, a college degree, a small business loan, or legal help for workplace discrimination, same model, entirely different doorways.
- Actionable gate-opening strategies, specific, real-world workarounds for each gate so you can stop asking "what's wrong with me?" and start asking "which gate is this, and how do I push through it?"
