Weekend Edition

Let me take a second here.

Not very long, was it?

But a second tied up delegates to the UN's International Telecommunication Union, who postponed a decision this week on whether to abolish the extra second that's added to clocks every few years to compensate for the earth's natural doddering.

The earth slows down slightly as we spin through space. No one falls off, but earthquakes and tides routinely slow the earth by a fraction of a fraction of a second, which makes clocks minutely wrong. If not corrected, it could make a minute of difference a century.

SCOTT SIMON, HOST:

Time now for your letters.

(SOUNDBITE OF TYPING AND MUSIC)

SIMON: Last week, we spoke with Clay Johnson, an open-source advocate and digital strategist, about his new book, "The Information Diet: A Case for Conscious Consumption."

CLAY JOHNSON: You know, our minds are really wired to be affirmed and to be told that we're right. And that's the central premise of "The Information Diet." It's really, who wants to hear the truth when they can hear that they're right?

One hundred years ago this week, British explorer Robert Falcon Scott reached the South Pole with a small crew of men. They all perished on the return trip. In 2008 on Weekend Edition, NPR's Daniel Zwerdling reported from the South Pole on Scott's tragic journey. To mark the 100th anniversary, we reprise that story.
