What is Mercury in Retrograde, and Why Do We Blame Things On It?

Crashed computers, missed flights, tensions in your workplace—a person who subscribes to astrology would tell you to expect all this chaos and more when Mercury starts retrograding. In 2018, that means March 23-April 15, July 26-August 19, and November 17-December 6. But according to an astronomer, this common celestial phenomenon is no reason to stay cooped up at home for weeks at a time.

"We don't know of any physical mechanism that would cause things like power outages or personality changes in people," Dr. Mark Hammergren, an astronomer at Chicago's Adler Planetarium, tells Mental Floss. So if Mercury doesn’t throw business dealings and relationships out of whack when it appears to change direction in the sky, why are so many people convinced that it does?

THE HISTORY

Mercury retrograde—as it's technically called—was being written about in astrology circles as far back as the mid-18th century. The event was noted in British agricultural almanacs of the time, which farmers would read to sync their planting schedules to the patterns of the stars. During the spiritualism craze of the Victorian era, interest in astrology boomed, with many believing that the stars affected the Earth in a variety of (often inconvenient) ways. Late 19th-century publications like The Astrologer’s Magazine and The Science of the Stars connected Mercury retrograde with heavy rainfall. Characterizations of the happening as an "ill omen" also appeared in a handful of articles during that period, but its association with outright disaster wasn’t as prevalent then as it is today.

While other spiritualist hobbies like séances and crystal gazing gradually faded, astrology grew even more popular. By the 1970s, horoscopes were a newspaper mainstay and Mercury retrograde was a recurring player. Because the Roman god Mercury was said to govern travel, commerce, financial wealth, and communication, in astrological circles, Mercury the planet became linked to those matters as well.

"Don’t start anything when Mercury is retrograde," an April 1979 issue of The Baltimore Sun instructed its readers. "A large communications organization notes that magnetic storms, disrupting messages, are prolonged when Mercury appears to be going backwards. Mercury, of course, is the planet associated with communication." The power attributed to the event has become so overblown that today it's blamed for everything from digestive problems to broken washing machines.

WHAT IS IT ACTUALLY?

Though hysteria around Mercury retrograde is stronger than ever, there's still zero evidence that it's something we should worry about. Even the flimsiest explanations, like the idea that the gravitational pull from Mercury influences the water in our bodies in the same way that the moon controls the tides, are easily deflated by science. "A car 20 feet away from you will exert a stronger pull of gravity than the planet Mercury does," Dr. Hammergren says.

To understand how little Mercury retrograde impacts life on Earth, it helps to learn the physical process behind the phenomenon. When the planet nearest to the Sun is retrograde, it appears to move "backwards" (east to west rather than west to east) across the sky. This apparent reversal in Mercury's orbit is actually just an illusion to the people viewing it from Earth. Picture Mercury and Earth circling the Sun like cars on a racetrack. A year on Mercury is shorter than a year on Earth (88 Earth days compared to 365), which means Mercury experiences four years in the time it takes us to finish one solar loop.

When the planets are next to one another on the same side of the Sun, Mercury looks like it's moving east to those of us on Earth. But when Mercury overtakes Earth and continues its orbit, its straight trajectory seems to change course. According to Dr. Hammergren, it's just a trick of perspective. "Same thing if you were passing a car on a highway, maybe going a little bit faster than they are," he says. "They're not really going backwards, they just appear to be going backwards relative to your motion."

Earth's orbit isn't identical to that of any other planet in the solar system, which means that all the planets appear to move backwards at varying points in time. Planets farther from the Sun than Earth have even more noticeable retrograde patterns because they're visible at night. But thanks to astrology, it's Mercury's retrograde motion that incites dread every few months.

Dr. Hammergren blames the superstition attached to Mercury, and astrology as a whole, on confirmation bias: "[Believers] will say, 'Aha! See, there's a shake-up in my workplace because Mercury's retrograde.'" He urges people to review the past year and see if the periods of their lives when Mercury was retrograde were especially catastrophic. They'll likely find that misinterpreted messages and technical problems are fairly common throughout the year. But as Dr. Hammergren says, when things go wrong and Mercury isn't retrograde, "we don't get that hashtag. It's called Monday."

Why Do Ants Die After the Queen Dies?

Eduardo Fox:

A fundamental fact about social Hymenoptera (wasps, ants) that most people, including entomologists, are unaware of: They cannot live without their larvae.

Next time you see an ant’s nest, a bee hive, or a hornet’s nest, remember: That structure is essentially a neonatal ICU!

Why? Look at an ant’s body below:


Clker.com via Quora

Did you notice the waist? I tell you: The individual’s stomach is located after the thin waist. That means an ant cannot eat solids.

Now, take a look at an ant’s larva (a & b, below):


Notice the waist? There’s none. It means larvae eat solid food!

So, this is what happens: Ants are working hard together in that nest mainly to bring up hundreds of babies. They come out to get food and bring it back to the nest, then they chew it up and place it on their larvae. Larvae will swallow and digest the food for them. Especially protein. Larvae secrete nutrient-rich liquids back to the ants, which is their main source of amino acids and fatty acids.

Who lays eggs to produce larvae? Queens.*

What happens when queens die? No eggs, hence no larvae.

What happens when there are no larvae? Bad nutrition, ultimately no reason for the nest. Ants gradually get disorganized, and after a few weeks they die.

Wasps and more "primitive" ants can more easily produce a new queen who will be the next mated female in the hierarchy. However, if none of them is fertile enough and mated, the nest won’t last long. Bees work differently.

* Important technical notice: Queens normally live longer than workers. Nowhere in this answer did I mean to imply that larvae can somehow enable workers to live as long as queens!

How Much Is Game of Thrones Author George RR Martin Worth?

Unsurprisingly, Game of Thrones took home another Emmy Award earlier this week for Outstanding Drama Series, which marked the series' third time winning the title. Of course, George RR Martin—the author who wrote the books that inspired the TV show, and the series' executive producer—celebrated the victory alongside ​the GoT cast.

For anyone who may be unfamiliar with Martin's work, he is the author of the A Song of Ice and Fire series, which is the epic fantasy series that led to the Game of Thrones adaptation. Basically, we really we have him to thank for this seven-year roller coaster we've been on.

At 70 years old (his birthday was yesterday, September 20th), Martin has had a fairly lengthy career as an author, consisting of a number of screenplays and TV pilots before A Song of Ice and Fire, which, ​according to Daily Mail he wrote in the spirit of The Lord of the Rings.

Martin sold the rights to his A Song of Ice and Fire series in 2007, and he truly owes the vast majority of his net worth to the success of his novels and the Game of Thrones TV series. So how much exactly is this acclaimed author worth? According to Daily Mail, Martin makes about $15 million annually from the TV show, and another $10 million from his successful literary works.

According to Celebrity Net Worth, that makes Martin's net worth about $65 million.

Regardless of his millions, Martin still lives a fairly modest life, and it's clear he does everything for his love of writing.

We'd like to extend a personal thank you to Martin for creating one of the most exciting and emotionally jarring storylines we've ever experienced.
We wish Game of Thrones could go ​on for 13 seasons, too!
