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.

Call to Action:🔹 Try it this week: Pick one interaction where you'll apply one of these power-ups.

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

Quote from the Episode

"As far as I can see, there could be no theory of games without that theorem … I thought there was nothing worth publishing until the Minimax Theorem was proved." - John von Neumann

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

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

1. 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.
2. 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.
3. 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.

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

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)
