The bomb (part 1): were nuclear weapons inevitable?

The bomb (part 1): were nuclear weapons inevitable?

Where did the world’s most devastating weapon come from? In a four-part series, we go behind the scenes at America's nuclear laboratories to understand how a scientific-mystery story about the ingredients of matter led to a world-changing (and second-world-war-ending) bomb less than five decades later.


Nuclear weapons have been central to geopolitical power ever since. Now America is seeking to modernise its stockpile and, in doing so, its scientists are pushing the frontiers of extreme physics, materials science and computing.


In episode one, we look at the birth of nuclear physics—the science that emerged early in the 20th century to answer a mystery: what is an atom actually made of?


Host: Alok Jha, The Economist’s science and technology editor. Contributors: Frank Close, a physicist and author of “Destroyer of Worlds”, a history of the birth of nuclear physics; Cheryl Rofer, a chemist who used to work at the Los Alamos National Laboratory (LANL); and Nicholas Lewis, a historian at LANL.

And then, silence: a Paris icon burns

Emmanuel Macron, France’s president, was already battling the flames of national protest when fire broke out at the Notre Dame cathedral. Will the tragedy, and Mr Macron’s leadership, bring the country together? America’s armed forces often don’t know how many civilians are killed in its air-strike campaigns—but that’s changing, thanks to help from some of the Pentagon’s loudest critics. And, the Trump administration’s cancellation of a deal for Cuban baseball players won’t stop them making their way, perilously, to the big leagues. Hosted on Acast.

And, the human family tree got bigger this week, but as new data flood in the murkier the human-evolution story seems to get. Hosted on Acast. See acast.com/privacy for more information.

Brussels’ doubts: another Brexit delay

Brussels’ doubts: another Brexit delay

Britain now has a new Brexit deadline: the end of October. But those negotiations magnified divisions within the European Union that Brexit is revealing—and causing.

Bibi got back: Israel’s election

Binyamin Netanyahu looks set to win a fifth term as prime minister. How will his policies affect negotiations about some of the most contested land on Earth? Meanwhile in space, Israel’s Beresheet probe is set to land on the Moon—but the recent spate of lunar landings is more about national flag-planting than it is about science.

The new mediocre: the world economy

The new mediocre: the world economy

The International Monetary Fund releases its global-growth forecast today. Expect news of a downgrade, but not recession: low growth has become the status quo.
