In this lecture, Lawrence H. White — Professor of Economics at George Mason University and Senior Fellow at the F. A. Hayek Program for Advanced Study in Philosophy, Politics, and Economics at the Mercatus Center — offers a comprehensive reading of one of the most consequential books of the 20th century.

Published in 1944, Hayek's The Road to Serfdom marked a turning point in his career: from technical monetary economist to public intellectual. White traces the historical context that made the book necessary — the intellectual prestige of central planning in the 1930s, FDR's New Deal and its corporatist inspiration, and the chilling admiration some American progressives harbored for Mussolini's "efficient" state apparatus.

White walks through the book's core arguments: why central planning is not merely economically inefficient but inherently incompatible with the rule of law and individual liberty; why partial interventionism tends to escalate rather than stabilize (Mises's logic of interventionism); and why, in a centrally planned system, it is the least scrupulous who tend to rise to positions of power.

The lecture also examines how the book was received — from Churchill's rhetorical overreach in the 1945 British elections to Paul Samuelson's influential (and deeply flawed) misreading — and closes with Keynes's famous letter from the ship to Bretton Woods: enthusiastic agreement in principle, followed by the conviction that good planning by the right people would make Hayek's warnings moot.

In this remarkable conversation, physicist and author Brian Greene sits down with Edward Witten — widely regarded as the greatest theoretical physicist of our era and the only scientist ever to receive the Fields Medal, the highest honor in mathematics — picking up a dialogue that began 39 years earlier at Harvard in 1986.

The evening explores some of the deepest questions in fundamental physics: what is quantum mechanics, and why is it so difficult to reconcile with Einstein's general relativity? Why does gravity continue to resist quantization? And where do we stand today in the search for a unified theory of everything?

At the heart of the discussion is String Theory — its history, its genuine breakthroughs (including the revolution of the 1990s and Maldacena's celebrated duality between gauge theory and gravity), and its still-unanswered challenges. Witten is candid: physicists have uncovered a vast and mathematically breathtaking structure, but the unifying principles behind it remain unknown. Unlike Einstein, who developed the concepts of general relativity first and then found the mathematics to match, string theory was stumbled upon without anyone knowing what it really was — and in many ways, that mystery persists to this day.

Greene and Witten also reflect on the sociology of science: the early resistance to string theory within the physics community, the courage required to bet an entire career on a radical idea, and the long periods of waiting and uncertainty that define life as a theoretical physicist. Witten admits that much of the time, doing research simply feels like hanging around doing nothing.

Physics has achieved extraordinary things — it can explain the behavior of matter from subatomic particles to galaxy clusters, trace the history of the universe back to fractions of a second after the Big Bang, and predict experimental outcomes with stunning precision. And yet, says theoretical physicist Sean Carroll, the deepest questions remain stubbornly, fascinatingly open.

In this lecture delivered at the Darwin College Lecture Series at Cambridge, Carroll takes listeners on a tour of the frontiers of modern physics — not the textbook version, but the genuinely unsettled, contested, and mysterious one. Three big themes structure the talk: the nature of quantum mechanics, the nature of space, and the nature of time.

Along the way, Carroll unpacks why physicists still don't agree on what quantum mechanics actually means — not just how to use it. He explores the many-worlds interpretation, the puzzle of quantum entanglement, and why the measurement problem is far from solved. He then turns to space and time: why does time have a direction at all? What does entropy really tell us about the arrow of time, the origin of complexity, and the fact that we — conscious beings — exist right now, at what Carroll calls "the fun Friday night of cosmic history"?

Beard opens with Charlotte Perkins Gilman's 1915 utopian novel Herland — a peaceful, well-organized all-female society — as a springboard for exploring the relationship between women and power in Western culture.

Her central argument is that our mental template for a "powerful person" remains stubbornly male. Women who reach positions of authority must adapt to that male template (trouser suits, lowered voices) precisely because no established cultural image of a powerful woman exists in its own right.

Tracing things back to ancient Greece, Beard shows how powerful women in mythology — Clytemnestra, the Amazons — are always portrayed as illegitimate usurpers of power, bringers of chaos, who must ultimately be defeated or destroyed. Even Lysistrata, which looks feminist on the surface, ends with women reduced to objects. This pattern, she argues, is far from ancient history: the severed head of Medusa is still deployed as a symbol against women in politics today. The starkest example is the viral image of Trump as Perseus holding up Hillary Clinton's head as Medusa's.

The solution Beard proposes is not simply to get more women into existing structures, but to redefine power itself — to detach it from individual prestige and hierarchical models, and understand it instead as a collective capacity to make a difference and be taken seriously. She points to the founders of Black Lives Matter — highly influential yet largely nameless — as an example of this different kind of power.

She closes by returning to Gilman: the sequel to Herland ends with the birth of a son, and Beard notes that any reader attuned to Western tradition would know exactly who would be running things fifty years later. The point is bleak but clear — the old stories are remarkably hard to dislodge.

In this thought-provoking lecture, Sean Carroll challenges one of the most fundamental ideas in human history: the concept of God as an explanatory theory of the universe.

Drawing from modern cosmology, quantum mechanics, and philosophy of science, Carroll argues that invoking God does not provide predictive power or scientific explanatory value. Instead, he explores how contemporary physics—especially our understanding of the laws of nature, the origin of the universe, and the structure of reality—offers a more rigorous framework for explaining existence without resorting to supernatural assumptions.

What is the true nature of the universe? In this fascinating lecture, Roger Penrose explores the deepest questions of cosmology, black holes, entropy, the Big Bang, quantum mechanics, and the future of physics. Drawing from decades of groundbreaking research in mathematics and theoretical physics, Penrose challenges conventional ideas about space, time, consciousness, and the origins of reality.

Why do some civilizations thrive for centuries while others suddenly collapse? In this thought-provoking talk, Jared Diamond explores the forces that determine whether societies survive or fail.

Drawing from history, archaeology, environmental science, and economics, Diamond examines famous collapses such as Easter Island, the Maya civilization, and Norse Greenland, connecting them to modern global challenges including climate change, resource depletion, and political instability.

In this conversation, Yuval Noah Harari and Jared Diamond explore the impact of artificial intelligence, social media, technology, history, and human evolution on modern civilization.

From the dangers of misinformation and digital addiction to the rise of AI and the fragility of democratic societies, Harari and Diamond analyze the challenges facing humanity in the 21st century — and what history can teach us about surviving them.
