Show Notes
It’s been 60 years, to the day, since Soviet cosmonaut Yuri Gagarin was the first human to travel to space in a tiny capsule attached to an R-7 ballistic missile, a powerful rocket originally designed to carry a three- to five-megaton nuclear warhead. In this new episode marking the 60th anniversary of this historic space flight—the first of its kind—Scientific American talks to Stephen Walker, an award-winning filmmaker, director and book author, about the daring launch that changed the course of human history and charted a map to the skies and beyond.
Walker discusses his new book Beyond: The Astonishing Story of the First Human to Leave Our Planet and Journey into Space, out today, and how Gagarin’s journey—an enormous mission that was fraught with danger and planned in complete secrecy—happened on the heels of a cold war between the U.S. and the Soviet Union and sparked a relentless space race between a rising superpower and an ailing one, respectively.
Walker, whose films have won an Emmy and a BAFTA, revisits the complex politics and pioneering science of this era from a fresh perspective. He talks about his hunt for eyewitnesses, decades after the event; how he uncovered never-before-seen footage of the space mission; and, most importantly, how he still managed to put the human story at the heart of a tale at the intersection of political rivalry, cutting-edge technology, and humankind’s ambition to conquer space and explore new frontiers.

On this show, we’ve been talking about uncertainty from a variety of different angles. We’ve heard how uncertainty can be a spark for creativity and scientific discovery. We’ve discussed how uncertainty can go unseen and make science really difficult. And we’ve explored some of the research techniques and habits of mind that researchers use to deal with uncertainty. Today we’re going to end with two final questions: If science is always uncertain, how can we ever know anything? How can we have confidence in science if there’s always underlying uncertainty?

Science is an iterative process. Progress comes from people coming up with ideas that are sort of right and then new evidence and ideas coming in to update them to become even more correct. Underlying this process is a willingness by scientists to accept that they might be wrong and be open to updating their ideas. It turns out that social scientists have a term for this mindset. To find out more, I talked with two researchers who are studying this thing they call “intellectual humility.” Learn more about your ad choices. Visit megaphone.fm/adchoices
Today’s episode of Uncertain is about the ways that studies can leave us overconfident and how “just-so stories” can make us feel overly certain about results that are still a work in progress. And sometimes studies get misleading results because of random error or weird samples or study design. But sometimes science gets things wrong because it’s done by humans, and humans are fallible and imperfect. Learn more about your ad choices. Visit megaphone.fm/adchoices
In this episode, we’ll talk with two researchers whose work probes the uncertainty surrounding how we perceive the world around us. It turns out that what we see may not always be a perfect reflection of reality.
Welcome to Uncertain, a five-part podcast miniseries from Scientific American. Here we will dive head first into the possibilities of the unknowing. Over the next five episodes, I’ll be talking with people like her: explorers who work in the realm of uncertainty. Through them, we’ll discover the ways that uncertainty can spark curiosity and scientific breakthroughs. But we’ll also find out how uncertainty can bite us in the butt and make science really hard. We’ll see how neglecting uncertainty can lead to overconfidence and how embracing uncertainty can allow for a more nuanced and accurate understanding of the world. We’ll finish by examining how it’s possible to have confidence in scientific findings, even with their uncertainties.
