Our series "Take A Number" looks at problems around the world — and the people trying to solve them — through the lens of a single number.

At the tiny public library in Winterport, Maine, 43-year-old Robert Hartmann bends over The Little Engine That Could and slowly sounds out the first line.

"Ch-chug, right?" he asks his volunteer tutor, Sandy DeLuck. "Yup," she encourages him. He presses on: "Puh-puff ... puff ... puff. Ding ... ding-dong?"

For Philip Schentrup, whose daughter Carmen was among the students killed at Marjory Stoneman Douglas High School in Parkland, Fla., each day brings the same, sharp pain. The same search for answers that don't come.

"To be honest, it's the same day I live over and over," he says. "Since February 14, this is every day. Every day of trying to hold yourself together."

"You search for normalcy, a 'new normal,'" he says, then pauses.

"I say those words. I don't really know what they mean yet."

It's been one month since the mass shooting at Stoneman Douglas.

The cauldron has been extinguished. The 23rd Olympic Winter Games has wrapped up in Pyeongchang, South Korea.

(SOUNDBITE OF ARCHIVED RECORDING)

CL: 2018, Korea. Let's go.

Olympic sports have their own special vernacular — colorful slang terms that are head-scratchers to an outsider.

Here in Pyeongchang, I've made it my mission to crack the code. So I cornered as many Olympic athletes as I could and asked them to divulge their terms of the trade.

When I asked U.S. biathlete Tim Burke for his best example, he didn't hesitate.

"If you have a bad crash, a lot of times we call that a 'yard sale,'" he told me.

Yard sale! I was intrigued.

Let's turn now to our team in Pyeongchang, South Korea. They have been spending time with a couple Olympic medalists in speedskating, both long and short track. Both of these formats can be pretty thrilling and also agonizing, as NPR's Melissa Block reports.

In the Winter Olympics, where races can be won or lost by thousandths of a second, tiny imperfections can make all the difference.

Nowhere is this more true than in the ice venues, where skilled technicians called "ice meisters" have honed their expertise over years of crafting the perfect surface.

Make that surfaces: It turns out that all ice is not created equal.

Depending on the sport, the ice might need to be softer or harder, colder or warmer, textured or smooth.

There are Olympic athletes, and then there are Olympic families. NPR's Melissa Block caught up with a famous former Olympian as she watched her daughter compete in South Korea.

UNIDENTIFIED CROWD: (Singing) We will, we will rock you.

Since she was a little girl, Ashley Caldwell has been in constant motion: jumping out of her crib, tumbling off the couch, leaping down stairs, flipping on a trampoline.

So it seems fitting that now, at 24, Caldwell is the reigning women's world champion in aerials skiing — a sport in which she somersaults and spins through the air, some 60 feet off the ground.
