11 Harry Potter Facts for His 33rd Birthday

Getty Images

In the Harry Potter universe, the famous boy wizard was born on July 31, 1980, which would make him a man wizard in his early thirties. (J.K. Rowling's birthday is also today.) To celebrate his 33rd birthday and her 48th, here are some Potter-related facts.

1. Michael Jackson wanted to do a musical version of Harry Potter and proposed the idea to J.K. Rowling. She said no.
*
2. Rowling created Quidditch in a pub after having a fight with her then-boyfriend. "In my deepest, darkest soul," she said, "I would quite like to see him hit by a bludger."
*
3. "Hogwarts Headache" is a thing. The New England Journal of Medicine ran a letter from a physician noting the unfortunate side effect of children reading more, and for longer periods, than they ever had in their lives.
*
4. Harry Potter and the Philosopher’s Stone became ...and the Sorcerer’s Stone in the United States. Other changes included “jumper” to “sweater,” “trainers” to “sneakers,” “car park” to “parking lot,” and “jacket potato” to “baked potato."
*
5. For years, an Onion article from 2000 titled “Harry Potter Books Spark Rise in Satanism Among Children” has been quoted as fact in chain emails. One oft-repeated fake quote: “Harry Potter books showed me that magic is real, something I can learn and use right now, and that the Bible is nothing but boring lies.”
*
6. Hermione Granger’s original surname was “Puckle.”
*
7. Hermione was originally going to have a younger sister, but Rowling never found the right moment to stick her into the books.
*
8. King’s Cross station is where young wizards hop on the Hogwarts Express to get to school. The station holds special meaning for J.K. Rowling: it’s where her parents met.
*
9. Not wanting her to be pigeonholed as a girls-only author, Joanne Rowling’s publisher asked her to write under androgynous initials. Not having a middle name, she picked “K” to honor her grandmother, Kathleen.
*
10. A retired professor from Eton College translated Harry Potter into Latin. Harry Potter and the Philosopher’s Stone became Harrius Potter et Philosophi Lapis. J.K. Rowling’s hope for the translations is that they “will help children overcome the common dread of studying" Latin.
*
11. Father Gabriele Amorth, the Vatican's former chief exorcist, says practicing yoga is Satanic. "It leads to evil—just like reading Harry Potter."

15 Confusing Plant and Animal Misnomers

People have always given names to the plants and animals around us. But as our study of the natural world has developed, we've realized that many of these names are wildly inaccurate. In fact, they often have less to say about nature than about the people who did the naming. Here’s a batch of these befuddling names.

1. COMMON NIGHTHAWK

There are two problems with this bird’s name. First, the common nighthawk doesn’t fly at night—it’s active at dawn and dusk. Second, it’s not a hawk. Native to North and South America, it belongs to a group of birds with an even stranger name: Goatsuckers. People used to think that these birds flew into barns at night and drank from the teats of goats. (In fact, they eat insects.)

2. IRISH MOSS

It’s not a moss—it’s a red alga that lives along the rocky shores of the northern Atlantic Ocean. Irish moss and other red algae give us carrageenan, a cheap food thickener that you may have eaten in gummy candies, soy milk, ice cream, veggie hot dogs, and more.

3. FISHER-CAT

Native to North America, the fisher-cat isn’t a cat at all: It’s a cousin of the weasel. It also doesn’t fish. Nobody’s sure where the fisher cat’s name came from. One possibility is that early naturalists confused it with the sea mink, a similar-looking creature that was an expert fisher. But the fisher-cat prefers to eat land animals. In fact, it’s one of the few creatures that can tackle a porcupine.

4. AMERICAN BLUE-EYED GRASS

American blue-eyed grass doesn’t have eyes (which is good, because that would be super creepy). Its blue “eyes” are flowers that peek up at you from a meadow. It’s also not a grass—it’s a member of the iris family.

5. MUDPUPPY

The mudpuppy isn’t a cute, fluffy puppy that scampered into some mud. It’s a big, mucus-covered salamander that spends all of its life underwater. (It’s still adorable, though.) The mudpuppy isn’t the only aquatic salamander with a weird name—there are many more, including the greater siren, the Alabama waterdog, and the world’s most metal amphibian, the hellbender.

6. WINGED DRAGONFISH

This weird creature has other fantastic and inaccurate names: brick seamoth, long-tailed dragonfish, and more. It’s really just a cool-looking fish. Found in the waters off of Asia, it has wing-like fins, and spends its time on the muddy seafloor.

7. NAVAL SHIPWORM

The naval shipworm is not a worm. It’s something much, much weirder: a kind of clam with a long, wormlike body that doesn’t fit in its tiny shell. It uses this modified shell to dig into wood, which it eats. The naval shipworm, and other shipworms, burrow through all sorts of submerged wood—including wooden ships.

8. WHIP SPIDERS

These leggy creatures are not spiders; they’re in a separate scientific family. They also don’t whip anything. Whip spiders have two long legs that look whip-like, but that are used as sense organs—sort of like an insect’s antennae. Despite their intimidating appearance, whip spiders are harmless to humans.

9. VELVET ANTS

There are thousands of species of velvet ants … and all are wasps, not ants. These insects have a fuzzy, velvety look. Don’t pat them, though—velvet ants aren’t aggressive, but the females pack a powerful sting.

10. SLOW WORM

The slow worm is not a worm. It’s a legless reptile that lives in parts of Europe and Asia. Though it looks like a snake, it became legless through a totally separate evolutionary path from the one snakes took. It has many traits in common with lizards, such as eyelids and external ear holes.

11. TRAVELER'S PALM

This beautiful tree from Madagascar has been planted in tropical gardens all around the world. It’s not actually a palm, but belongs to a family that includes the bird of paradise flower. In its native home, the traveler’s palm reproduces with the help of lemurs that guzzle its nectar and spread pollen from tree to tree.

12. VAMPIRE SQUID

This deep-sea critter isn’t a squid. It’s the only surviving member of a scientific order that has characteristics of both octopuses and squids. And don’t let the word “vampire” scare you; it only eats bits of falling marine debris (dead stuff, poop, and so on), and it’s only about 11 inches long.

13. MALE FERN & LADY FERN

Early botanists thought that these two ferns belonged to the same species. They figured that the male fern was the male of the species because of its coarse appearance. The lady fern, on the other hand, has lacy fronds and seemed more ladylike. Gender stereotypes aside, male and lady Ferns belong to entirely separate species, and almost all ferns can make both male and female reproductive cells. If ferns start looking manly or womanly to you, maybe you should take a break from botany.

14. TENNESSEE WARBLER

You will never find a single Tennessee warbler nest in Tennessee. This bird breeds mostly in Canada, and spends the winter in Mexico and more southern places. But early ornithologist Alexander Wilson shot one in 1811 in Tennessee during its migration, and the name stuck.

15. CANADA THISTLE

Though it’s found across much of Canada, this spiky plant comes from Europe and Asia. Early European settlers brought Canada thistle seeds to the New World, possibly as accidental hitchhikers in grain shipments. A tough weed, the plant soon spread across the continent, taking root in fields and pushing aside crops. So why does it have this inaccurate name? Americans may have been looking for someone to blame for this plant—so they blamed Canada.
