Robert Krulwich

Robert Krulwich works on radio, podcasts, video, the blogosphere. He has been called "the most inventive network reporter in television" by TV Guide.

Krulwich is a Science Correspondent for NPR. His NPR blog, "Krulwich Wonders" features drawings, cartoons and videos that illustrate hard-to-see concepts in science.

He is the co-host of Radiolab, a nationally distributed radio/podcast series that explores new developments in science for people who are curious but not usually drawn to science shows. "There's nothing like it on the radio," says Ira Glass of This American Life, "It's a act of crazy genius." Radiolab won a Peabody Award in 2011.

His specialty is explaining complex subjects, science, technology, economics, in a style that is clear, compelling and entertaining. On television he has explored the structure of DNA using a banana; on radio he created an Italian opera, "Ratto Interesso" to explain how the Federal Reserve regulates interest rates; he has pioneered the use of new animation on ABC's Nightline and World News Tonight.

For 22 years, Krulwich was a science, economics, general assignment and foreign correspondent at ABC and CBS News.

He won Emmy awards for a cultural history of the Barbie doll, for a Frontline investigation of computers and privacy, a George Polk and Emmy for a look at the Savings & Loan bailout online advertising and the 2010 Essay Prize from the Iowa Writers' Workshop.

Krulwich earned a Bachelor of Arts degree in history from Oberlin College and a law degree from Columbia University.

On Thanksgiving, Everybody Needs A Friend — And That Means Everybody

Last December, a website called The Morning News asked me to describe the most important and unimportant events of my year. So I sent them a story that felt like both to me, something slight but at the same time deeply rich. Now that it's Thanksgiving, I'm going to post it here because it's about two girls who want the best for everybody — and that can get complicated.

Born Wet, Human Babies Are 75 Percent Water. Then Comes Drying

Robert Krulwich NPR

Look at this baby.

Lovely, no? Now think of this baby abstractly — as a sack of hundreds of millions of atoms. Here's the atomic formula for a new human being, arranged by elements, according to scientist Neil Shubin.

What We Can Never, Ever Know: Does Science Have Limits?

Originally published on Fri September 6, 2013 1:10 pm

I got two books in the mail that, if they could have, would've poked, scratched and ripped each others' pages out. I don't know if Martin Gardner and Patricia Churchland ever met, but their books show that there are radically, even ferociously, different ways to think about science. Gardner died last year. He was a science writer whose monthly "Mathematical Games" column in Scientific American was wildly popular. Patricia Churchland is a philosopher who teaches at U.C. San Diego.

The issue between them is: How much can we know about the universe?

Wild Things Hanging From Spruce Trees

Robert Krulwich NPR

Originally published on Thu September 5, 2013 10:45 am

Stanley Kunitz, one of our great poets, planted a spruce tree next to his house in Provincetown, Mass., and over the years that tree attracted some tenants, a family of garden snakes. I didn't know garden snakes climb trees, especially needly ones like a spruce, but they do.

Drone It To Me, Baby

Spies used them first, then the Air Force, then cops, then mischievous civilians; drones, for some reason, are what gawkers use to gawk. They're spy accessories. But not only spy accessories. Thanks to Jasper van Loenen, drones are about to expand their repertoire. The word "drone" is about to become a verb, as in "Drone it to me"...

Watch Me Do Something Impossible In Three Totally Easy Steps

Robert Krulwich NPR

Originally published on Fri August 9, 2013 7:19 pm

Here's what the Swedish artist Oscar Reutersvard did. In 1934, he got himself a pen and paper and drew four cubes, like this.

Then he drew some more, like this.

And, then — and this is where he got mischievous — he drew one more set, like this.

He called this final version "Impossible Triangle of Opus 1 No. 293aa." I don't know what the "293aa" is about, but he was right about "impossible." An arrangement like this cannot take place in the physical universe as we know it.

The Subtle Mysteries Of Dinosaur Sex

Robert Krulwich NPR

Originally published on Tue August 6, 2013 11:33 am

They dominated our planet for 130 million years. You can't do that without having babies, and to have babies, dinosaurs had to have sex. The mystery is — and this is still very much a mystery — we don't really know how they did it.

The key problems being:

First, dinosaur ladies and dinosaur gentlemen were roughly the same size. No big/little asymmetry as with spiders. With spiders, the little fellow mounts the big lady. There are no body-crushing weight issues.

Mysterious Dancing Lights In Afghanistan

Courtesy of Michael Yon

This isn't a painting. It's not from a movie. It's not a strange astronomical event. This is real — what you can see when certain helicopters in Afghanistan touch down on sandy ground, raising dust, causing mysterious arcs of light to loop and dance through the air.

This doesn't always happen. "The halos usually disappear as the rotors change pitch," wrote war photographer Michael Yon. "On some nights, on this very same landing zone, no halos form." How come?
