Brooke Buddemeier and Jessica S. Wieder: Can you survive nuclear fallout?

Nuclear weapons are some of the most powerful tools of destruction on Earth, and the full scope of a nuclear detonation is almost unimaginable. However, there is a scientifically supported plan of action that could save thousands of lives. What is this plan, and what exactly would it protect us from? Brooke Buddemeier and Jessica S. Wieder explo...

Emma Belcher: 3 questions we should ask about nuclear weapons

There are more than 10,000 nuclear weapons in existence today, each one capable of causing immense destruction. Why don't we talk about this threat as much as some other major issues? In this practical talk, nuclear security expert Emma Belcher shares three questions you can ask your elected officials to gain a better understanding of nuclear we...

Erika Gregory: The world doesn't need more nuclear weapons

Today nine nations collectively control more than 15,000 nuclear weapons, each hundreds of times more powerful than those dropped on Hiroshima and Nagasaki. We don't need more nuclear weapons; we need a new generation to face the unfinished challenge of disarmament started decades ago. Nuclear reformer Erika Gregory calls on today's rising leade...

Alex Rosenthal: Can you solve the rogue submarine riddle? Difficulty level: Master

Smuggling yourself aboard the rogue submarine was the easy part. Hacking into the nuclear missile launch override — a little harder. And you've got a problem: you don't have the override code. You know you need the same numbers that were used to authorize the launch, but one wrong answer will lock you out. Can you figure out what numbers to ente...

Taylor Wilson: Yup, I built a nuclear fusion reactor

Taylor Wilson believes nuclear fusion is a solution to our future energy needs, and that kids can change the world. And he knows something about both of those: When he was 14, he built a working fusion reactor in his parents' garage. Now 17, he takes the TED stage at short notice to tell (the short version of) his story.

Holly Morris: Why stay in Chernobyl? Because it's home.

Chernobyl was the site of the world's worst nuclear accident and, for the past 27 years, the area around the plant has been known as the Exclusion Zone. And yet, a community of about 200 people live there -- almost all of them elderly women. These proud grandmas defied orders to relocate because their connection to their homeland and to their co...

Diana Adams: Why US laws must expand beyond the nuclear family

The nuclear family model may no longer be the norm in the US, but it's still the basis for social and economic benefits like health care, tax breaks and citizenship. Lawyer and LBGTQIA advocate Diana Adams believes that all families, regardless of biological relationship or legal marriage, are deserving of equal legal rights and recognition. The...

TED-Ed: How much land does it take to power the world?

No matter how we make electricity, it takes up space. Coal requires mines, and plants to convert it into electricity. Nuclear power takes uranium mines, facilities to refine it, a reactor, and a place to store the spent fuel safely. Renewable energy needs wind turbines or solar panels. So how much space would it take to power the whole world? Ex...
