Nobody ever claimed a visit to the doctor was a pleasant way to pass the time. But if you're timid about diving onto a psychiatrist's couch or paranoid about popping pills, remember: It could be worse. Like getting-a-hole-drilled-into-your-skull worse.

1. INSULIN COMA-THERAPY

The coma-therapy trend began in 1927. Viennese physician Manfred Sakel accidentally gave one of his diabetic patients an insulin overdose, and it sent her into a coma. But what could have been a major medical faux pas turned into a triumph. The woman, a drug addict, woke up and declared her morphine craving gone. Later, Sakel (who really isn't earning our trust here) made the same mistake with another patient—who also woke up claiming to be cured. Before long, Sakel was intentionally testing the therapy with other patients and reporting a 90 percent recovery rate, particularly among schizophrenics. Strangely, however, Sakel's treatment successes remain a mystery.

Presumably, a big dose of insulin causes blood sugar levels to plummet, which starves the brain of food and sends the patient into a coma. But why this unconscious state would help psychiatric patients is anyone's guess. Regardless, the popularity of insulin therapy faded, mainly because it was dangerous. Slipping into a coma is no walk in the park, and between one and two percent of treated patients died as a result.

2. TREPANATION

Ancient life was not without its hazards. Between wars, drunken duels, and the occasional run-in with an inadequately domesticated pig, it's no surprise that archaic skulls tend to have big holes in them. But not all holes are created with equal abandon. Through the years, archaeologists have uncovered skulls marked by a carefully cut circular gap, which shows signs of being made long before the owner of the head passed away. These fractures were no accident; they were the result of one of the earliest forms of psychiatric treatment called trepanation. The basic theory behind this "therapy" holds that insanity is caused by demons lurking inside the skull. As such, boring a hole into the patient's head creates a door through which the demons can escape, and—voila!—out goes the crazy.

Despite the peculiarity of the theory and lack of major-league anesthetics, trepanation was by no means a limited phenomenon. From the Neolithic era to the early 20th century, cultures all over the world used it as a way to cure patients of their ills. Doctors eventually phased out the practice as less invasive procedures were developed. Average Joes, on the other hand, didn't all follow suit. Trepanation patrons still exist. In fact, they even have their very own organizations, like the International Trepanation Advocacy Group.

3. ROTATIONAL THERAPY

Charles Darwin's grandfather Erasmus Darwin was a physician, philosopher, and scientist, but he wasn't particularly adept at any of the three. Consequently, his ideas weren't always taken seriously. Of course, this could be because he liked to record them in bad poetic verse (sample: "By immutable immortal laws / Impress'd in Nature by the great first cause, / Say, Muse! How rose from elemental strife / Organic forms, and kindled into life"). It could also be because his theories were a bit far-fetched, such as his spinning-couch treatment. Darwin's logic was that sleep could cure disease and that spinning around really fast was a great way to induce the slumber.

Nobody paid much attention to Darwin's idea at first, but later, American physician Benjamin Rush adapted the treatment for psychiatric purposes. He believed that spinning would reduce brain congestion and, in turn, cure mental illness. He was wrong. Instead, Rush just ended up with dizzy patients. These days, rotating chairs are limited to the study of vertigo and space sickness.

4. HYDROTHERAPY

If the word "hydrotherapy" conjures up images of Hollywood stars lazily soaking in rich, scented baths, then you probably weren't an early 20th-century psychiatric patient. Building off the idea that a dip in the water is often calming, psychiatrists of yore attempted to remedy various symptoms with corresponding liquid treatments. For instance, hyperactive patients got warm, tiring baths, while lethargic patients received stimulating sprays.

Some doctors, however, got a bit too zealous about the idea, prescribing therapies that sounded more like punishment than panacea. One treatment involved mummifying the patient in towels soaked in ice-cold water. Another required the patient to remain continuously submerged in a bath for hours or even days—which might not sound so bad, except they were strapped in and only allowed out to use the restroom. Finally, some doctors ordered the use of high-pressure jets. Sources indicate that at least one patient was strapped to the wall in the crucifixion position (never a good sign) and blasted with water from a fire hose. Like many extreme treatments, hydrotherapy was eventually replaced with psychiatric drugs, which tended to be more effective.

5. MESMERISM

Much like Yoda, Austrian physician Franz Mesmer (1734-1815) believed that an invisible force pervaded everything in existence, and that disruptions in this force caused pain and suffering. But Mesmer's ideas would have been of little use to Luke Skywalker. His basic theory was that the gravity of the moon affected the body's fluids in much the same way it caused ocean tides, and that some diseases accordingly waxed and waned with the phases of the moon. The dilemma, then, was to uncover what could be done about gravity's pernicious effects. Mesmer's solution: use magnets. After all, gravity and magnetism were both about objects being attracted to each other. Thus, placing magnets on certain areas of a patient's body might be able to counteract the disruptive influence of the moon's gravity and restore the normal flow of bodily fluids.

Surprisingly, many patients praised the treatment as a miracle cure, but the medical community dismissed it as superstitious hooey and chalked up his treatment successes to the placebo effect. Mesmer and his theories were ultimately discredited, but he still left his mark. Today, he's considered the father of modern hypnosis because of his inadvertent discovery of the power of suggestion, and his name lives on in the English word mesmerize

6. MALARIA THERAPY

Ah, if only we were talking about a therapy for malaria. Instead, this is malaria as therapy—specifically, as a treatment for syphilis. There was no cure for the STD until the early 1900s, when Viennese neurologist Wagner von Jauregg got the idea to treat syphilis sufferers with malaria-infected blood. Predictably, these patients would develop the disease, which would cause an extremely high fever that would kill the syphilis bacteria. Once that happened, they were given the malaria drug quinine, cured, and sent home happy and healthy. The treatment did have its share of side effects—that nasty sustained high fever, for one—but it worked, and it was a whole lot better than dying. In fact, Von Jauregg won the Nobel Prize for malaria therapy, and the treatment remained in use until the development of penicillin came along and gave doctors a better, safer way to cure the STD.

7. CHEMICALLY INDUCED SEIZURES

Nobody ever said doctors had flawless logic. A good example: seizure therapy. Hungarian pathologist Ladislas von Meduna pioneered the idea. He reasoned that, because schizophrenia was rare in epileptics, and because epileptics seemed blissfully happy after seizures, then giving schizophrenics seizures would make them calmer. In order to do this, von Meduna tested numerous seizure-inducing drugs (including such fun candidates as strychnine, caffeine, and absinthe) before settling on metrazol, a chemical that stimulates the circulatory and respiratory systems. And although he claimed the treatment cured the majority of his patients, opponents argued that the method was dangerous and poorly understood.

To this day, no one is quite clear on why seizures can help ease some schizophrenic symptoms, but many scientists believe the convulsions release chemicals otherwise lacking in patients' brains. Ultimately, the side effects (including fractured bones and memory loss) turned away both doctors and patients.

8. PHRENOLOGY

Around the turn of the 19th century, German physician Franz Gall developed phrenology, a practice based on the idea that people's personalities are depicted in the bumps and depressions of their skulls. Basically, Gall believed that the parts of the brain a person used more often would get bigger, like muscles. Consequently, these pumped-up areas would take up more skull space, leaving visible bumps in those places on your head. Gall then tried to determine which parts of the skull corresponded to which traits. For instance, bumps over the ears meant you were destructive; a ridge at the top of the head indicated benevolence; and thick folds on the back of the neck were sure signs of a sexually oriented personality. In the end, phrenologists did little to make their mark in the medical field, as they couldn't treat personality issues, only diagnose them (and inaccurately, at that). By the early 1900s, the fad had waned, and modern neuroscience had garnered dominion over the brain.

9. HYSTERIA THERAPY

Once upon a time, women suffering from pretty much any type of mental illness were lumped together as victims of hysteria. The Greek physician Hippocrates popularized the term, believing hysteria encompassed conditions ranging from nervousness to fainting fits to spontaneous muteness. The root cause, according to him, was a wandering womb. So, whither does it wander? Curious about Hippocrates's theory, Plato asked himself that very question. He claimed that if the uterus "remains unfruitful long beyond its proper time, it gets discontented and angry and wanders in every direction through the body, closes up the passages of the breath, and, by obstructing respiration, drives women to extremity." Consequently, cures for hysteria involved finding a way to "calm down" the uterus. And while there was no dearth of methods for doing this (including holding foul-smelling substances under the patient's nose to drive the uterus away from the chest), Plato believed the only surefire way to solve the problem was to get married and have babies. After all, the uterus always ended up in the right place when it came time to bear a child. Although "womb-calming" as a psychiatric treatment died out long ago, hysteria as a diagnosis hung around until the 20th century, when doctors began identifying conditions such as depression, post-traumatic stress disorder, and phobias.

10. LOBOTOMY

Everybody's favorite psychiatric treatment, the modern lobotomy was the brainchild of António Egas Moniz, a Portuguese doctor. Moniz believed that mental illnesses were generally caused by problems in the neurons of the frontal lobe, the part of the brain just behind the forehead. So when he heard about a monkey whose violent, feces-throwing urges had been curbed by cuts to the frontal lobe, Moniz was moved to try out the same thing with some of his patients. (The lobe-cutting, not the feces-throwing.) He believed the technique could cure insanity while leaving the rest of the patient's mental function relatively normal, and his (admittedly fuzzy) research seemed to support that. The accolades flooded in, and (in one of the lower points in the Karolinska Institute's history) Moniz was awarded the Nobel Prize in 1949.

After the lobotomy rage hit American shores, Dr. Walter Freeman took to traveling the country in his "lobotomobile" (no, really), performing the technique on everyone from catatonic schizophrenics to disaffected housewives. His road-ready procedure involved inserting a small ice pick into the brain through the eye socket and wiggling it around a bit. While some doctors thought he'd found a way to save hopeless cases from the horrors of life-long institutionalization, others noted that Freeman didn't bother with sterile techniques, had no surgical training whatsoever, and tended to be a bit imprecise when describing his patients' recovery.

As the number of lobotomies increased, a major problem became apparent: The patients weren't just calm—they were virtual zombies who scarcely responded to the world around them. Between that and the bad press lobotomies received in films and novels such as One Flew Over the Cuckoo's Nest, the treatment soon fell out of favor.

15 Facts About Nicolaus Copernicus

Polish astronomer and mathematician Nicolaus Copernicus fundamentally altered our understanding of science. Born on February 19, 1473, he popularized the heliocentric theory that all planets revolve around the Sun, ushering in the Copernican Revolution. But he was also a lifelong bachelor and member of the clergy who dabbled in medicine and economics. Dive in to these 15 facts about the father of modern astronomy.

1. He came from a family of merchants and clergy.

Some historians believe that Copernicus's name derives from Koperniki, a village in Poland named after tradesmen who mined and sold copper. The astronomer's father, also named Nicolaus Copernicus, was a successful copper merchant in Krakow. His mother, Barbara Watzenrode, came from a powerful family of merchants, and her brother, Lucas Watzenrode the Younger, was an influential Bishop. Two of Copernicus's three older siblings joined the Catholic Church, one as a canon and one as a nun.

2. He was a polyglot.

Growing up, Copernicus likely knew both Polish and German. When Copernicus's father died when he was around 10, Lucas Watzenrode funded his nephew's education and he started learning Latin. In 1491, Copernicus began studying astronomy, math, philosophy, and logic at Krakow University. Five years later, he headed to modern Italy's Bologna University to study law, where he likely picked up some Italian. During his studies, he also read Greek, meaning modern historians think he knew or understood five languages.

3. He wasn't the first person to suggest heliocentrism ...

Copernicus is credited with introducing heliocentrism—the idea that the Earth orbits the sun, rather than the sun orbiting the Earth. But several ancient Greek and Islamic scholars from various cultures discussed similar ideas centuries earlier. For example, Aristarchus of Samos, a Greek astronomer who lived in the 200s BCE, theorized that Earth and other planets revolved around the Sun.

4. … but he didn't fully give credit to earlier scholars.

To be clear, Copernicus knew of the work of earlier mathematicians. In a draft of his 1543 manuscript, he even included passages acknowledging the heliocentric ideas of Aristarchus and other ancient Greek astronomers who had written previous versions of the theory. Before submitting the manuscript for publication, though, Copernicus removed this section; theories for the removal range from wanting to present the ideas as wholly his own to simply switching out a Latin quote for a "more erudite" Greek quote and incidentally removing Aristarchus. These extra pages weren't found for another 300-some years.

5. He made contributions to economics.

He's known for math and science, but Copernicus was also quite the economist. In 1517, he wrote a research paper outlining proposals for how the Polish monarch could simplify the country's multiple currencies, especially in regard to the debasement of some of those currencies. His ideas on supply and demand, inflation, and government price-fixing influenced later economic principles such as Gresham's Law (the observation that "bad money drives out good" if they exchange for the same price; for example, if a country has both a paper $1 bill and a $1 coin, the value of the metal in the coin is higher than the value of the cotton and linen in the bill, and thus the bill will be spent as currency more because of that) and the Quantity Theory of Money (the idea that the amount of money in circulation is proportional to how much goods cost).

6. He was a physician (but he didn't have a medical degree).

After studying law, Copernicus traveled to the University of Padua so he could become a medical advisor to his sick uncle, Bishop Watzenrode. Despite spending two years studying medical texts and learning anatomy, Copernicus left medical school without a doctoral degree. Nevertheless, he traveled with his uncle and treated him, as well as other members of the clergy who needed medical attention.

7. He was probably a lifelong bachelor …

As an official in the Catholic Church, Copernicus took a vow of celibacy. He never married and was most likely a virgin (more on that below), but children were not completely absent from his life: After his older sister Katharina died, he became the financial guardian of her five children, his nieces and nephews.

8. … But he may have had an affair with his housekeeper.

Copernicus took a vow of celibacy, but did he keep it? In the late 1530s, the astronomer was in his sixties when Anna Schilling, a woman in her late forties, began living with him. Schilling may have been related to Copernicus—some historians think he was her great uncle—and she worked as his housekeeper for two years. For unknown reasons, the bishop he worked under admonished Copernicus twice for having Schilling live with him, even telling the astronomer to fire her and writing to other church officials about the matter.

9. He attended four universities before earning a degree.

Copernicus spent over a decade studying at universities across Poland and Italy, but he usually left before he got his degree. Why skip the diplomas? Some historians argue that at the time, it was not unusual for students to leave a university without earning a degree. Moreover, Copernicus didn't need a degree to practice medicine or law, to work as a member of the Catholic Church, or even to take graduate or higher level courses. 

But right before returning to Poland he received a doctorate in canon law from the University of Ferrara. According to Copernicus scholar Edward Rosen this wasn't exactly for scholarly purposes, but that to "show that he had not frittered his time away on wine, women, and song, he had to bring home a diploma. That cost much less in Ferrara than in the other Italian universities where he studied."

10. He was cautious about publicizing his views.

During Copernicus's lifetime, nearly everyone believed in geocentrism—the view that the Earth lies at the center of the universe. Despite that, in the 1510s Copernicus wrote Commentariolus, or "the Little Commentary," a short text that discussed heliocentrism and was circulated amongst his friends. It was soon found circulating further afield, and it's said that Pope Clement VII heard a talk about the new theory and reacted favorably. Later, Cardinal Nicholas Schönberg wrote a letter of encouragement to Copernicus, but Copernicus still hesitated in publishing the full version. Some historians propose that Copernicus was worried about ridicule from the scientific community due to not being able to work out all of the issues heliocentrism created. Others propose that with the rise of the Reformation, the Catholic Church was increasingly cracking down on dissent and Copernicus feared persecution. Either way, he didn't make his complete work public until 1543.

11. He published his work on his deathbed.

Copernicus finishing writing his book explaining heliocentrism, De Revolutionibus Orbium Coelestium (On the Revolutions of Celestial Orbs), in the 1530s. When he was on his deathbed in 1543, he finally decided to publish his controversial work. According to lore, the astronomer awoke from a coma to read pages from his just-printed book shortly before passing away.

12. Galileo was punished for agreeing with Copernicus.

Copernicus dedicated his book to the Pope, but the Catholic Church repudiated it decades after it was published, placing it on the Index of Prohibited Books—pending revision—in 1616. A few years later, the Church ended the ban after editing the text to present Copernicus's views as wholly hypothetical. In 1633, 90 years after Copernicus's death, the Church convicted astronomer Galileo Galilei of "strong suspicion of heresy" for espousing Copernicus's theory of heliocentrism. After a day in prison, Galileo spent the rest of his life under house arrest.

13. There's a chemical element named after him.

Take a look at the periodic table of elements, and you might notice one with the symbol Cn. Called Copernicium, this element with atomic number 112 was named to honor the astronomer in 2010. The element is highly radioactive, with the most stable isotope having a half life of around 30 seconds.

14. Archaeologists finally discovered his remains in 2008.

Although Copernicus died in 1543 and was buried somewhere under the cathedral where he worked, archaeologists weren't sure of the exact location of his grave. They performed excavations in and around Frombork Cathedral, finally hitting pay dirt in 2005 by finding part of a skull and skeleton under the church's marble floor, near an altar. It took three years to complete forensic facial reconstruction and compare DNA from the astronomer's skeleton with hair from one of his books, but archeologists were able to confirm that they had found his skeleton. Members of the Polish clergy buried Copernicus for a second time at Frombork in 2010.

15. THERE ARE MONUMENTS TO HIM AROUND THE WORLD.

A prominent statue of the astronomer, simply called the Nicolaus Copernicus Monument, stands near the Polish Academy of Sciences in Warsaw, Poland. There are also replicas of this monument outside Chicago's Adler Planetarium and Montreal's Planétarium Rio Tinto Alcan. Besides monuments, Copernicus also has a museum and research laboratory—Warsaw's Copernicus Science Centre—dedicated to him.

11 Spectacular Facts About the Moon

The Moon is Earth’s closest satellite in our solar system, but in many ways, we hardly know our neighbor. Scientists aren’t entirely sure how it formed, and other facts, like its shape (more egg-like than spherical), and the consistency of its surface (dusty but firm), were confirmed only recently. With the 50th anniversary of the Apollo 11 Moon landing this year, and NASA preparing to return to the lunar surface for the first time in decades, it’s time to brush up on these facts about the Moon—from colorful names for full moons to the first landing on the dark side of the Moon.

1. The Moon may have formed when a giant object in the solar system hit Earth.

Scientists aren't in total agreement on how the Moon formed, but the most widely accepted theory is the giant impact hypothesis. According to this theory, an object the size of Mars called Theia collided with Earth 4.5 billion years ago when the solar system was still new and chaotic. The impact dislodged matter from Earth’s crust, and the debris attached to whatever was left of Theia through the force of gravity.

This scenario would explain why the Moon is made up of lighter elements found in Earth’s outer layer, but it still leaves some questions unanswered. If the giant impact hypothesis is correct, about 60 percent of the Moon should consist of the impact object. Instead, its composition is almost identical to that of Earth. There are alternative explanations: one posits that the Moon is a space object that got caught in Earth’s orbit, and another one suggests the Moon and Earth formed at the same time, but none is as popular as the giant impact theory.

2. The Moon is the perfect size for solar eclipses.

A lucky set of circumstances make total solar eclipses, as seen from Earth, possible. The Moon is just the right size and distance from our planet to appear as the same size as the Sun in the sky. When the Moon passes between the Sun and the Earth, it covers the Sun perfectly with an impressive corona illuminating its edges. If it were any smaller or farther from Earth, it would look like a blot on the Sun during a solar eclipse.

3. A full Moon has different nicknames in different seasons.

A full moon can have many colorful names, but they don’t always describe a special celestial phenomenon. Some are used to refer to a full moon that appears during a certain time of year. A harvest moon, which is the full moon closest to the autumn equinox, is the best-known example, but there are many others, including a wolf moon (first full moon of January), strawberry moon (June), and sturgeon moon (August).

4. It’s the largest moon in the solar system relative to its planet.

Our Moon isn’t the largest in the solar system (that distinction goes to Ganymede, one of Jupiter’s 79 moons), but it is the biggest in relation to the planet it orbits. With a diameter of 2159 miles and a surface area of 14.6 million square miles, the Moon is a little more than one-fourth the size of Earth. The dwarf planet Pluto has an even smaller moon-to-planet ratio. Pluto’s largest moon Charon is nearly the size of its host body, leading some astronomers to refer to the pair as a double-dwarf planet.

5. The Moon is shaped like a lemon.

The Moon may look perfectly round in the night sky, but it’s actually more of an oval shape. It came out wonky billions of years ago when super-hot tidal forces shaped its crust, heating up some areas hotter than others to form a lemon shape rather than a perfect sphere. Gravitational forces from Earth have helped to exaggerate the Moon’s oblong appearance over eons.

6. Scientists thought Moon dust would cause lunar landers to sink.

When preparing to send missions to the Moon, some scientists feared that a thick layer of dust on the body’s surface would cause complications. One of the strongest proponents of the dust theory was Thomas Gold, an astrophysicist at Cornell University. He insisted that the Moon was covered in seas of dust soft and thick enough to swallow a lunar lander. Though the Moon’s surface is dusty, the layer is too thin to cause problems, as the successful landings of the Soviet Luna 9 and the American Surveyor spacecrafts proved in 1966.

7. The Moon is international property.

Astronauts Buzz Aldrin and Neil Armstrong may have planted an American flag on the Moon in 1969, but it belongs to the world. Countries like the Soviet Union and the U.S. made sure of that at the height of the space race in 1967 when they signed the Outer Space Treaty, a document declaring that the Moon would be a “global commons” and any resources discovered there would be used for the good of the world overall. In keeping with the spirit of the agreement, NASA shared soil samples taken from the Moon with Soviet scientists upon the Apollo 11 mission's return.

8. Humans have left strange things on the Moon.

Since the first people landed on the Moon in 1969, its surface has been home to more than just dust. Earth artifacts left on the Moon by astronauts include two golf balls, an obscene Andy Warhol doodle, and a message from Queen Elizabeth II. Eugene Cernan, Apollo 17 commander and one of the last people to walk on the Moon, traced his daughter’s initials into the soil when he visited in 1972. Without any wind or weather on the Moon, the letters TDC could remain there forever.

9. The "dark side of the Moon" is the result of synchronous rotation.

Even though the Moon is constantly rotating, only one side of it is visible from Earth. This is because the Moon is locked in synchronous rotation. It takes the Moon just as long to complete one full rotation as it does for the body to orbit around the Earth once, so the same side always faces our planet. This isn’t a coincidence—the Earth’s gravitational forces have gradually pulled the tip of the slightly oblong Moon to point toward the planet, creating something called tidal lock.

In January 2019, the Chinese space agency landed the first lunar probe on the unexplored dark side of the Moon. The Chang'e 4 spacecraft sent the first photographs of a massive impact crater on the dark side to Earth, giving scientists their first glimpse of that unknown region.

10. One astronaut was allergic to the Moon.

Apollo 17 astronaut Harrison “Jack” Schmitt discovered the hard way that some people are allergic to Moon matter. Following a survey of a valley in the Sea of Serenity, he climbed back into the crew’s lunar module and tracked in a lot of Moon dust with him. The dust affected him as soon as he removed his spacesuit, triggering red eyes, sneezing fits, and other symptoms that lasted two hours.

11. Humans are going back to the Moon soon.

After completing several manned missions to the Moon, NASA ended the Apollo program in 1972 as budgets tightened and public interest waned. That means most people alive today have never witnessed a manned lunar landing, but now, following a hiatus nearing 50 years, NASA is finally preparing to return to the Moon. The next manned lunar expedition will be ready to launch “no later than the late 2020s,” according to the space agency. One of the goals will be placing a command module, called Gateway, in the Moon’s orbit that astronauts can reuse over multiple missions.
