What does it cost to carry a brilliant idea? Ludwig Boltzmann gave us the statistical foundations of entropy and the famous S = k log W, yet his life was marked by relentless skepticism, isolation, and personal struggle. In this episode, we weave Boltzmann’s story with the modern mental health crisis in academia, where anxiety, depression, and burnout affect scientists at alarming rates. We’ll explore how probability explains not only the arrow of time, but also why community, resilience, and care are essential for science to thrive. 3 Things Listeners Will Learn: How Ludwig Boltzmann’s statistical mechanics shaped modern physics and why his ideas met fierce resistance. The scale of today’s mental health crisis in academia — from graduate students to faculty. Practical tools like cognitive behavioral therapy (CBT) and community support that can help foster resilience in science.

We use maps all day, including Google Maps, Waze, Apple Maps. We use them without even noticing that every one of them distorts reality. In this episode, Gabrielle explains why flattening a round Earth always bends the truth, how classic projections (like Mercator) live inside today’s apps, and why those distortions shape our mental picture of the world. Practical, visual, and myth-busting, this is cartography you can feel on your daily commute.  To hear the podcast on Marie Tharp, visit: Math Science History with Gabrielle Birchak Three Coordinates to Remember Why distortion is unavoidable when projecting a 3D globe onto a flat screen (thanks, Gauss). How Web Mercator powers Google Maps/Waze, great for street-level navigation, misleading at global scales.

Whether it's the silent symmetry of Islamic domes or the loud clatter of skyscrapers rising, construction is the sound of applied mathematics — past and present. Three take-aways: How ancient builders used geometry, Pythagorean triples, and astronomy to align massive structures like the pyramids. The mathematical innovations behind historical architectural marvels like Brunelleschi’s dome and the Roman Pantheon. How modern construction relies on physics, calculus, AI, and computer simulations — and what those sounds mean today.

In this episode of Math! Science! History!, Gabrielle explores the unexpected origin story of the word scientist. It all started with Mary Somerville’s 1834 book On the Connexion of the Physical Sciences, which sparked a humorous yet historic review by William Whewell. From ridicule to resistance, the term evolved amid fierce linguistic debate, public mockery, and eventual global adoption. Discover how one word came to define a profession, and why that battle still matters today. Key topics: The origin of the word "scientist," and why it was initially mocked by 19th-century intellectuals. How Mary Somerville’s work unified the physical sciences and inspired a linguistic revolution. Why scientists still face resistance, and why naming, truth, and peer-reviewed research matter more than ever.

In this Flashcard Friday episode of Math, Science, History, host Gabrielle Birchak takes you into the steamy jungles of the 19th-century Malay Archipelago, where a fever-stricken explorer had a revelation that would change biology forever. Meet Alfred Russel Wallace, the naturalist whose fieldwork and tropical travels led to the theory of natural selection, at the same time as Darwin. From his challenging journey to his humility in the face of discovery, Wallace’s story reminds us that science doesn’t always happen in a lab. It sometimes happens in a mosquito-filled hut, guided by sheer determination and a passion for nature. Do you know?!  - How Alfred Russel Wallace independently developed the theory of natural selection during his expedition? - The significance of the "Wallace Line" and its impact on biogeography? - Why Wallace’s collaboration with Darwin remains a model of scientific integrity and humility?
