The Most Astonishing Wave-Tracking Experiment Ever

Sean Gallup Getty Images

I'm standing on a beach and I see, a few hundred yards out, a mound of water heading right at me. It's not a wave, not yet, but a swollen patch of ocean, like the top of a moving beach ball, what sailors call a "swell." As it gets closer, its bottom hits the rising shore below, forcing the water up, then over, sending it tumbling onto the beach, a tongue of foam coming right up to my toes — and that's when I look down, as the wave melts into the sand and I say,

"Hi, I'm from New York. But what about you? Where are you from?"

They're odds. That's all they are. Not fate, just probabilities. Lauren Weinstein, cartoonist, is having a baby, and she's told — out of the blue — that she and her husband are both carriers of the gene that causes cystic fibrosis. They are sent to a genetic counselor. What happens next — told in five beautifully drawn, emotionally eloquent cartoons — tells what it's like to walk the edge for a few weeks. She's so many things (sad, funny, scared, puzzled), and then there's the ender. Take a look.

OK, I'm doing great science experiments. We've done sex (see previous post). On to lunch!

Robert Krulwich NPR

Originally published on Mon June 30, 2014 3:19 pm

Done right, a good science experiment is simple, clear and revealing. Done splendidly, it's a tale you don't forget. Let's do the sex one first. It took place in Italy, in the 1760s, when a Catholic priest and scholar, Lazzaro Spallanzani, was thinking about sperm — which is why he decided to dress frogs in pants, like this ...

We live in a sea of air. It holds us, weighs on us, keeps us tethered. The earth, of course, holds us too, keeps us pinned. But not all of us. I want you to meet Storyboard P, a dancer who floats.

Lights, Lights, Lights, Action! A Crazy New Light Projector

Originally published on Mon June 16, 2014 11:25 am

What can you do with a spotlight?

You can light a spot.

But what if you give yourself more options and invent a tool that lets light spill, splash or tighten into a beam as thin as a pencil line — a beam of light that can draw!

Draw what? Oh my God, so many things: a galloping unicorn, a friendly girl, a guy who kicks you in the face, a wormhole, a ball that splashes into a fluid, a cube, a spiral, a rabbit, a squid, a scribble.
