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.

As President Donald Trump delays further tariffs on $200bn-worth of Chinese goods, there are hints of an end to the trade war.

Alms held up: Venezuela

Alms held up: Venezuela

Venezuela is in dire need of humanitarian aid, and Juan Guaidó, the interim president, has pledged to deliver it tomorrow. Will Nicolás Maduro, the dictatorial leader still formally in power, let him? Ahead of Warren Buffett’s annual letter to shareholders, we look back on a half-century’s-worth of wisdom from the “Sage of Omaha”. And in Japan, longer lives are leading to more books by and for the elderly. Hosted on Acast. See acast.com/privacy for more information.

Sins of the fathers: the Vatican and child abuse

Sins of the fathers: the Vatican and child abuse

The Vatican is hosting a high-profile meeting on child abuse by the clergy. It’s a topic that has been woefully overlooked, and one that threatens to define the tenure of Pope Francis. We visit the world’s largest building, in the city of Chengdu. Inside there’s a giant wave pool, thirty thousand workers, free cats—and a glimpse of the state of China’s economy. And, an effort to resurrect the native language of Hawaii has brought unexpected benefits. Hosted on Acast. See acast.com/privacy for more information.

Prince on tour: Muhammad bin Salman

Prince on tour: Muhammad bin Salman

Muhammad bin Salman, the Saudi crown prince, is on a tour of Asia, striking deals and trying to polish his image. What kind of influence will he have in the region? Every year as much as a quarter of the global corporate-tax bill is avoided—legally. We take a look at where all that money is going. And we speak to Nadine Labaki, the first female Arab film-maker nominated for an Oscar. Hosted on Acast. See acast.com/privacy for more information.

Labour’s love lost: British politics

Labour’s love lost: British politics

Seven parliamentarians have split from Britain’s opposition Labour party. That could change the calculus of Brexit, and just might be the nucleus of a new movement. There’s a little-noticed shift in the relationship between Islam and the West; a new generation is lighting the way. And our Russia editor has a bit of a hobby—one that puts him at the nexus of language, drama and truth. Hosted on Acast. See acast.com/privacy for more information.

We examine the aftermath of the online behemoth’s withdrawal of its New York expansion plans, and speak with its Midwestern workers about growing talk of unionising. President Emmanuel Macron hopes to quell protests across France with a series of “town halls”; we drop into one. And mezcal is on the rise, but can tequila’s more-traditional cousin survive if the whole world wants a shot?Music credit: "Chez Space" by The Freeharmonic Orchestra (CC-BY) Hosted on Acast.

Emergency measures: America’s border deal

Emergency measures: America’s border deal

President Donald Trump is expected to declare a national emergency today, to fund his southern-border wall. We ask why that would be an uncomfortable constitutional precedent. Nigeria’s general election this weekend will be a nail-biter, and allegations of electoral fraud are already flying; the only certainty is that the result will be contested. And, we bid farewell to Opportunity, a Mars rover that vastly exceeded what was expected of it. Hosted on Acast. See acast.com/privacy for more information.
