Why Won't Team USA Dip the Flag at the Opening Ceremonies?

For the last 110 years, Olympic spirit has come with an asterisk for the United States, as we're the only country that refuses to dip its flag when passing the host country during the Opening Ceremonies.

Let's back up: During the Opening Ceremonies, every nation’s team parades in behind one member who holds the country’s flag. In the stands sit the governing officials of the host country. As the team marches past this section, the flag bearer lowers the flag as a sign of respect. Every country does the dip, except for the United States. The small move of respect has been a thorn in the sides of host countries since the U.S. first snubbed the tradition at the 1908 London Games.

The story goes that the 1908 U.S. flag bearer, shotputter Ralph Rose, kept the flag erect as an act of nationalism, proclaiming, "This flag dips to no earthly king.” However, according to Penn State professor Mark Dyreson, that story may not be exactly true. In 2012, Dyreson—who studies the Olympics—told the Los Angeles Times that America's refusal to participate in the flag-dipping tradition is a bit more complicated.

Rather than being a matter of good old American pride, Dyreson said that the Irish-American athlete’s actions were more about disdain for the British. In that era, Irish athletes riled at competing under the Union Jack. And there's no hard evidence the "no earthly king" quip was ever even muttered.

Until 1936, the practice to dip or not to dip flip-flopped. King Gustav V received a dipped flag in the 1912 Games, but 1936 was an easy call: The U.S. nearly didn’t participate in the Berlin Summer Olympics, let alone dip a flag in respect to Adolf Hitler. The decision to not dip was announced beforehand, and the U.S. was joined in protest by Bulgaria, Iceland, and India, according to contemporary media reports. The move wasn't even the athlete's decision—it was a top-down call from the United States Olympic Committee and, as traditions often begin, it just stuck. (In the 1940s, the tradition was formalized in the flag code, which reads “the flag should not be dipped to any person or thing.”)

So when we don't dip our flag, it's not pride. It's not hubris. It's not nationalism. It's just a big middle finger to Hitler.

Why Are Sloths So Slow?

When it comes to physical activity, few animals have as maligned a reputation as the sloth. The six sloth species, which call Brazil and Panama home, move with no urgency, having seemingly adapted to an existence that allows for a life lived in slow motion. But what makes sloths so sedate? And what horrible, poop-related price must they pay in order to maintain life in the slow lane?

According to HowStuffWorks, the sloth’s limited movements are primarily the result of their diet. Residing mainly in the canopy vines of Central and South American forests, sloths dine out on leaves, fruits, and buds. With virtually no fat or protein, sloths conserve energy by taking a leisurely approach to life. On average, a sloth will climb or travel roughly 125 feet per day. On land, it takes them roughly one minute to move just one foot.

A sloth’s digestive system matches their locomotion. After munching leaves using their lips—they have no incisors—it can take up to a month for their meals to be fully digested. And a sloth's metabolic rate is 40 to 45 percent slower than most mammals' to help compensate for their low caloric intake. With so little fuel to burn, a sloth makes the most of it.

Deliberate movement shouldn’t be confused for weakness, however. Sloths can hang from branches for hours, showing off some impressive stamina. And because they spend most of their time high up in trees, they have no need for rapid movement to evade predators.

There is, however, one major downside to the sloth's leisurely lifestyle. Owing to their meager diet, they typically only have to poop once per week. Like going in a public bathroom, this can be a stressful event, as it means going to the ground and risking detection by predators—which puts their lives on the line. Worse, that slow bowel motility means they’re trying to push out nearly one-third of their body weight in feces at a time. It's something to consider the next time you feel envious of their chill lifestyle.

Are Any of the Scientific Instruments Left on the Moon By the Apollo Astronauts Still Functional?

C Stuart Hardwick:

The retroreflectors left as part of the Apollo Lunar Ranging Experiment are still fully functional, though their reflective efficiency has diminished over the years.

This deterioration is actually now delivering valuable data. The deterioration has multiple causes including micrometeorite impacts and dust deposition on the reflector surface, and chemical degradation of the mirror surface on the underside—among other things.

As technology has advanced, ground station sensitivity has been repeatedly upgraded faster than the reflectors have deteriorated. As a result, measurements have gotten better, not worse, and measurements of the degradation itself have, among other things, lent support to the idea that static electric charge gives the moon an ephemeral periodic near-surface pseudo-atmosphere of electrically levitating dust.

No other Apollo experiments on the moon remain functional. All the missions except the first included experiment packages powered by radiothermoelectric generators (RTGs), which operated until they were ordered to shut down on September 30, 1977. This was done to save money, but also because by then the RTGs could no longer power the transmitters or any instruments, and the control room used to maintain contact was needed for other purposes.

Because of fears that some problem might force Apollo 11 to abort back to orbit soon after landing, Apollo 11 deployed a simplified experiment package including a solar-powered seismometer which failed after 21 days.
