Ira writes: In an edit of Gabriel Rhodes's story, I mistakenly asked him to insert erroneous information about sound waves and electromagnetic waves, and then acted so completely confident about it—misremembering a science show I worked on years ago—that nobody in the editing process bothered to fact check it. The people in the story were using electromagnetic waves, not sound waves, for their experiment. This was very much my mistake and not Gabe's, and I regret telling him to insert a mistake into his otherwise carefully researched and fact checked story. Thanks to the many listeners who wrote to point out the error. We've gone back and fixed this, so the versions aired in 2012 and posted here on the website have the correction.
- Host Ira Glass talks with science writer Paul Hoffman about a mathematician named Frank Nelson Cole, who demonstrated a groundbreaking idea at a conference in 1903. Paul explains that in addition to their celebrated breakthroughs, many of the greatest thinkers in history have entertained some very crazy ideas. Paul is the author of many books including The Man Who Loved Only Numbers, and is director of the Liberty Science Center in New Jersey. (7 minutes)
