In this fascinating conversation, I interview theoretical physicist Dr. Ronald Mallett to explore one of humanity's most extraordinary scientific pursuits: time travel. From the influence of Einstein's general theory of relativity to quantum mechanics and parallel universes, Dr. Mallett shares the story of how his personal loss inspired a lifetime of discovery. Listeners will hear how his work connects the geometry of spacetime, wormholes, and cosmic strings to the real mathematics of time loops, and how time travel to the past is theoretically possible. The discussion also takes an emotional and philosophical turn, as Dr. Mallett reflects on his book Time Traveler: A Scientist's Personal Mission to Make Time Travel a Reality and the hopes of seeing his father's memory brought to life on the big screen. Three Things You'll Learn: Einstein's Relativity and the Mechanics of Time Loops: How frame dragging, rotation, and gravity could allow time to twist back on itself. Quantum Mechanics and the Multiverse Solution: Why physicists like Hugh Everett and David Deutsch believe time travel could avoid paradoxes through parallel universes. Real-World Implications of Time Travel: From predicting natural disasters to advancing communication and transportation, Dr. Mallett explains how this science could one day reshape our future.

In this Halloween-special episode of Math! Science! History!, your host Gabrielle Birchak explores the strange world where superstition meets science. We dive into why machines sometimes bow to the mere presence of an engineer (the "Engineer Proximity Effect") and how one of the greatest physicists of the 20th century, Wolfgang Pauli, became the subject of an odd legend: wherever he went, lab equipment failed (the "Pauli Effect"). Join us for a spooky, fun, and surprisingly rational journey into the magical aura of tech support and haunted machines. Three Take-aways Why machines seem to fix themselves when the engineer enters the room, and the psychological and procedural forces behind the so-called Engineer Proximity Effect. The story behind the Pauli Effect, the absurd, amusing, and true folklore of Wolfgang Pauli and failing lab apparatus when he was nearby. How you can use a "spellbook for engineers" to break the cycle of tech gremlins, practical, science-based "spells" you can actually use to feel like you're doing a bit of Halloween magic while being perfectly logical.

In this episode of Math! Science! History!, Gabrielle Birchak speaks with Professor Gillen D'Arcy Wood, author of The Wake of the HMS Challenger: How a Legendary Victorian Voyage Tells the Story of Our Ocean's Decline. Together, they uncover how a nineteenth-century Royal Navy warship transformed into a floating laboratory and gave humanity its first global snapshot of the oceans. From discovering thousands of new species to inspiring NASA's Challenger shuttle, the expedition shaped modern oceanography and continues to inform today's conservation science. Wood's biocentric storytelling reminds us that to save our planet, we must first fall in love with it again, to be, as he says, re-enchanted by the living ocean that sustains us all. Three Things Listeners Will Learn How the HMS Challenger (1872–1876) became the first global oceanographic expedition, collecting temperature, depth, and biological data still used today. Why Gillen D'Arcy Wood's "biocentric" approach reframes history through the perspective of marine life rather than human explorers. What the voyage teaches us about modern ocean crises: from overfishing and warming seas to microplastics—and how species like the green turtle show that recovery is possible.

Publish or Purrish: The Cat Who Co-Authored Physics Episode Overview: In this episode of Math! Science! History!, we uncover the remarkable story of F.D.C. Willard, the Siamese cat who became a published co-author in a world-renowned physics journal. What began as a workaround for rigid authorship conventions turned into a beloved legend in science history. But Willard wasn't alone. We also take a closer look at other non-human co-authors, from a dog in immunology, to a hamster in physics, and even bonobos in language research, while exploring what these unusual stories reveal about the culture of scientific publishing and the pressures of the "publish or perish" system. Three Takeaways:  The real physics behind Willard's paper and why the study of helium-3 was serious science, not just a playful prank. Other cases of animals as authors—including a dog, a hamster, and three bonobos—and what those choices meant.

In this Flashcard Friday follow-up to Tuesday's interview with Dr. Kanisorn Wongsrichanalai of the Massachusetts Historical Society, we revisit the numbers that changed the course of history. During the Revolutionary War, smallpox was more dangerous to the Continental Army than the British. By comparing mortality rates, George Washington made a bold, science-driven choice: inoculate his troops. The math was simple but profound, 30% risk of death without inoculation versus just 2% with it. This decision helped save the Revolution. In this episode, we reiterate Dr. Wongsrichanalai's quote: "do the math, believe the science, and learn your history." From spotting misleading anecdotes to recognizing reliable sources, and from Washington's decision to Edward Jenner's breakthrough, today's lesson is that evidence and history are our best guides when confronting fear and misinformation. Three Things You'll Learn How arithmetic saved an army — Why the difference between 30% and 2% mortality mattered more than opinions. How to vet science today — Which sources are reliable and why consensus matters more than a single flashy headline. What history teaches us about vaccines — From smallpox inoculation to global eradication, the past shows us how trust in evidence safeguards survival.

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.

In this urgent episode of Math! Science! History, Gabrielle Birchak exposes how the United States is dismantling its scientific foundation through lawsuits, defunding, censorship, and intimidation. From shuttered labs to banned books and silenced climate scientists, Gabrielle connects today's attacks on knowledge to historical examples of authoritarian suppression—from Galileo's house arrest to the German Reich's university purges and Stalin's pseudoscience. This is more than a culture war; it's a battle for truth itself. If science falls, society falters. History has shown us the red flags—will we recognize them before it's too late? Three key takeaways Historical Warnings – How past regimes like Germany's Third Reich, Stalin's Soviet Union, and Mao's China crippled their own futures by silencing science. Present-Day Threats – The U.S. government's defunding of universities, dismantling of climate research, and politicization of curricula. How to Act – Practical ways to defend truth, support at-risk scholars, protect data, and safeguard scientific integrity globally.
