6 Reasons Today's Olympic Swimmers are Breaking so many World Records

For some reason every swim event in this Olympics is a record smasher. And it isn't just Michael Phelps who's seconds ahead of that daunting green world record line. Curious what's making this year's athletes so much faster? Here are 6 possible answers.

1. Tech Doping

Picture 46.pngThe new Speedo LZR RACER suit, which was developed by scientists from NASA, "feels like a rocket coming off the wall," said Phelps in a team interview. "The water just runs off the suit." The suit has "ultrasonically welded" seams that mimics a shark skin, holds in the swimmer's abdomen in the best position, allowing him to take in 5% more oxygen, and takes an athlete 30 minutes to get into!

2. The Pool Depth Matters

The pool in Beijing, known as the "Water Cube," is 3 meters deep, instead of the previous depth of 2 meters. This allows swimmers to dive deeper and continue their push off "dolphin kicks" for a longer period of time. Olympic medalist and commentator Rowdy Gaines says, "It's just deep enough to where the waves dissipate (and) the turbulence dissipates down to the bottom."

3. Empty Pool Lanes

There are ten lanes in the Water Cube, instead of the usual eight, leaving the outside lanes open. This reduces turbulence and enables swimmers to go faster. "It's by far the fastest pool in the world," Gaines says.

4. More Time to Practice

Sponsorship for swimming has increased massively, which allows athletes to practice more. Mark Spitz, the Olympic swimmer with the most gold medals before Phelps, retired at 22 due to his inability to make a living as an amateur athlete. Back then, the Olympics only allowed amateur athletes to compete. Phelps, on the other hand, is now 23 has an estimated annual earnings of $5 million, and will be awarded an extra $1 million dollar bonus from Speedo if he reaches or beats Spitz's record.

5. Old-fashioned Doping

Gary Hall Jr., previous Olympian 50-m freestyle champion, seems to think so. "Can suit technology distract from another issue?... I'm telling you this, I train with an international group of swimmers and all of them have stories and a few of them have had offers." Hall likens today's "blame it on the suit" situation to that of the '76 East German women's Olympic swimming team. Though, he seems to be the only one speaking out about this so perhaps he's just bitter he didn't qualify for Beijing.

6. The Secret Benefits of Math

Professor Timothy Wei, of Rensselaer Polytechnic Institute in Troy, N.Y., helped develop top-secret, state-of-the-art equipment and mathematical techniques that USA Swimming coaches have been using to help to make swimmers go faster. He uses water flow diagnostic technologies to see how each swimmers' motion affects the flow of water. The whole thing is explained here in this video.

Is There a Limit to How Many Balls You Can Juggle?

In 2017, a juggler named Alex Barron broke a record when he tossed 14 balls into the air and caught them each once. The feat is fascinating to watch, and it becomes even more impressive once you understand the physics behind it.

As WIRED explains in a new video, juggling any more than 14 balls at once may be physically impossible. Researchers who study the limits of juggling have found that the success of a performance relies on a number of different components. Speed, a.k.a. the juggler's capacity to move their hands in time to catch each ball as it lands, is a big one, but it's not the most important factor.

What really determines how many balls one person can juggle is their accuracy. An accurate juggler knows how to keep their balls from colliding in midair and make them land within arm's reach. If they can't pull that off, their act falls apart in seconds.

Breaking a juggling world record isn't the same as breaking a record for sprinting or shot put. With each new ball that's added to the routine, jugglers need to toss higher and move their hands faster, which means their throws need to be significantly more accurate than what's needed with just one ball fewer. And skill and hours of practice aren't always enough; according to expert jugglers, the current world records were likely made possible by a decent amount of luck.

The great Yogi Berra—a 10-time World Series champion and three-time MVP—was one of baseball's best catchers, but he's remembered just as much for his wit and wisdom as his Hall of Fame career. Here are some of the quotes attributed to Yogi (who was born on May 12, 1925), even if he didn't always say them first.

1. "Always go to other people's funerals, otherwise they won't go to yours."

2. "The future ain't what it used to be." (Yogi later clarified, saying, "I just meant that times are different. Not necessarily better or worse, just different.")

3. "A nickel ain't worth a dime anymore."

4. "It ain't over 'til it's over."

5. "When you come to a fork in the road, take it." (See Quote Investigator)

6. "Nobody goes there anymore. It's too crowded." (See Quote Investigator)

7. "We have a good time together, even when we're not together."

8. "It's déjà vu all over again." (See Quote Investigator)

9. "Baseball is 90 percent mental. The other half is physical."

10. "I really didn't say everything I said."

11. "Then again, I might have said 'em, but you never know."
