President Trump has often accused the news media of not covering terrorist attacks adequately. In a speech in February he said, "Radical Islamic terrorists are determined to strike our homeland as they did on 9/11, as they did from Boston to Orlando to San Bernardino [...] It's gotten to a point where it's not even being reported."

Magic.

That's what it feels like when you bump into your childhood friend on the first day of college ... or meet someone at a party in Paris, only to discover she lives in your dad's childhood home in Poughkeepsie, N.Y. But mathematician Joseph Mazur says these coincidences are not as extraordinary as we might think.

"People think that their address book is essentially the people they know, and it turns out any address book is about one percent of the people they know in some way," Mazur explains.

So we know that a picture speaks a thousand words, but NPR's Shankar Vedantam is here to tell us how it also gives us really strong impressions of people that we can't seem to shake. Hi, Shankar.

We heard a lot during the presidential campaign about the wage gap, the fact that women often earn less than men for the same kinds of work. Hillary Clinton pushed that issue, and she lost. But it remains a reality in many people's lives.

"Clean up this mess!"

This is a command you've probably given or received in your life. Perhaps in the last day, or even the last hour.

To many of us, the desire to bring order to chaos – to tidy up our kids' toys, organize an overstuffed closet, or rake the leaves covering the lawn – can be nearly irresistible. And it's a desire that extends to other aspects of our lives: Managers tell employees to get organized. Politicians are elected on promises to clean up Washington. And so on.

It's no secret that this presidential campaign season has been tense, with disagreement and rancor even louder than usual.

You might know slow motion from watching sports, showing collisions between cars, maybe football players taking hits. Well, there's social science research about the effect slow motion has on us, and we are joined by NPR's Shankar Vedantam. Hey, Shankar.
