Duolingo recently rolled out a new feature that includes a dynamic list of vocabulary terms as new lessons are completed. I love this feature and its way of keeping track of words and phrases that are getting rusty, but I want a way to categorize the terms based on subject. Until a feature like that rolls out (if ever), I’m going to start posting subject- and lesson-specific vocabulary lists for Duolingo Spanish.

Jellyfish Sprite
Red sprites or the tentacle-like spurts of red lightning in the sky during a storm are sometimes referred to as Jellyfish Sprite (because of their shape). There are also some that are vertical columns of red light and those are called carrot sprites.
They are ultra fast electricity traveling through the atmosphere towards space and are extremely rare (they last a tenth of a second). They can also be seen from space.

Here it is folks:
My definitive ranking of my least favorite bodies of water! These are ranked from least to most scary (1/10 is okay, 10/10 gives me nightmares). I’m sorry this post is long, I have a lot of thoughts and feelings about this.
The Great Blue Hole, Belize
I’ve been here! I have snorkeled over this thing! It is terrifying! The water around the hole is so shallow you can’t even swim over the coral without bumping it, and then there’s a little slope down, and then it just fucking drops off into the abyss! When you’re over the hole the water temperature drops like 10 degrees and it’s midnight blue even when you’re right by the surface. Anyway. The Great Blue Hole is a massive underwater cave, and its roughly 410 feet deep. Overall, it’s a relatively safe area to swim. It’s a popular tourist attraction and recreational divers can even go down and explore some of the caves. People do die at the Blue Hole, but it is generally from a lack of diving experience rather than anything sinister going on down in the depths. My rating for this one is 1/10 because I’ve been here and although it’s kinda freaky it’s really not that bad.
Lake Baikal, Russia
When I want to give myself a scare I look at the depth diagram of this lake. It’s so deep because it’s not a regular lake, it’s a Rift Valley, A massive crack in the earth’s crust where the continental plates are pulling apart. It’s over 5,000 feet deep and contains one-fifth of all freshwater on Earth. Luckily, its not any more deadly than a normal lake. It just happens to be very, very, freakishly deep. My rating for this lake is a 2/10 because I really hate looking at the depth charts but just looking at the lake itself isn’t that scary.
Jacob’s Well, Texas
This “well” is actually the opening to an underwater cave system. It’s roughly 120 feet deep, surrounded by very shallow water. This area is safe to swim in, but diving into the well can be deadly. The cave system below has false exits and narrow passages, resulting in multiple divers getting trapped and dying. My rating is a 3/10, because although I hate seeing that drop into the abyss it’s a pretty safe place to swim as long as you don’t go down into the cave (which I sure as shit won’t).
The Devil’s Kettle, Minnesota
This is an area in the Brule River where half the river just disappears. It literally falls into a hole and is never seen again. Scientists have dropped in dye, ping pong balls, and other things to try and figure out where it goes, and the things they drop in never resurface. Rating is 4/10 because Sometimes I worry I’m going to fall into it.
Flathead Lake, Montana
Everyone has probably seen this picture accompanied by a description about how this lake is actually hundreds of feet deep but just looks shallow because the water is so clear. If that were the case, this would definitely rank higher, but that claim is mostly bull. Look at the shadow of the raft. If it were hundreds of feet deep, the shadow would look like a tiny speck. Flathead lake does get very deep, but the spot the picture was taken in is fairly shallow. You can’t see the bottom in the deep parts. However, having freakishly clear water means you can see exactly where the sandy bottom drops off into blackness, so this still ranks a 5/10.
The Lower Congo River, multiple countries
Most of the Congo is a pretty normal, if large, River. In the lower section of it, however, lurks a disturbing surprise: massive underwater canyons that plunge down to 720 feet. The fish that live down there resemble cave fish, having no color, no eyes, and special sensory organs to find their way in the dark. These canyons are so sheer that they create massive rapids, wild currents and vortexes that can very easily kill you if you fall in. A solid 6/10, would not go there.
Little Crater Lake, Oregon
On first glance this lake doesn’t look too scary. It ranks this high because I really don’t like the sheer drop off and how clear it is (because it shows you exactly how deep it goes). This lake is about 100 feet across and 45 feet deep, and I strongly feel that this is too deep for such a small lake. Also, the water is freezing, and if you fall into the lake your muscles will seize up and you’ll sink and drown. I don’t like that either. 7/10.
Grand Turk 7,000 ft drop off
No. 8/10. I hate it.
Gulf of Corryvreckan, Scotland
Due to a quirk in the sea floor, there is a permanent whirlpool here. This isn’t one of those things that looks scary but actually won’t hurt you, either. It absolutely will suck you down if you get too close. Scientists threw a mannequin with a depth gauge into it and when it was recovered the gauge showed it went down to over 600 feet. If you fall into this whirlpool you will die. 9/10 because this seems like something that should only be in movies.
The Bolton Strid, England
This looks like an adorable little creek in the English countryside but it’s not. Its really not. Statistically speaking, this is the most deadly body of water in the world. It has a 100% mortality rate. There is no recorded case of anyone falling into this river and coming out alive. This is because, a little ways upstream, this isn’t a cute little creek. It’s the River Wharfe, a river approximately 30 feet wide. This river is forced through a tiny crack in the earth, essentially turning it on its side. Now, instead of being 30 feet wide and 6 feet deep, it’s 6 feet wide and 30 feet deep (estimated, because no one actually knows how deep the Strid is). The currents are deadly fast. The banks are extremely undercut and the river has created caves, tunnels and holes for things (like bodies) to get trapped in. The innocent appearance of the Strid makes this place a death trap, because people assume it’s only knee-deep and step in to never be seen again. I hate this river. I have nightmares about it. I will never go to England just because I don’t want to be in the same country as this people-swallowing stream. 10/10, I live in constant fear of this place.
Honorable mention: The Quarry, Pennsylvania
I don’t know if that’s it’s actual name. This lake gets an honorable mention not because it’s particularly deep or dangerous, but it’s where I almost drowned during a scuba diving accident.
Edit: I’ve looked up the name of the quarry, it’s called Crusty’s Quarry and is privately owned and only used for training purposes, not recreational diving.

by Laure S
emeritus: a well-meaning retired professor who still frequents the department. occasionally seen jogging up and down the halls of the lab. it’s how he gets his daily exercise. his field of research is obsolete and he spends most of his days making art based on physics equations. asks all of the female undergrads if they plan to teach high school physics.
star child: no one will measure up to this alumnus. they started research in high school, graduated from undergrad a year early with a few papers already under their belt, and finished their phd (at a very prestigious university) in two years. they visit occasionally to present their research and talk to the undergrad physics students. very down to earth and kind. undergrads, grad students, and professors alike are in awe.
father figure: this prof’s lectures are full of dad jokes, metaphors comparing the behaviors of particles with sugared-up three-year-olds, and digressions about something that’s more fun to talk about than the subject matter. says “i’m not angry, just disappointed” when the class does poorly on an exam. when you go to his office hours there is almost always a child or two underneath his desk or drawing on his whiteboard (the bottom third of which is always covered in stick figures and scribbles). intensely watched the construction from his office window as a new laboratory was being built.
academic rival: you were friends over the summer when you were both doing research but they became distant. small talk always turns into bickering about the importance of your respective research when you run into each other getting coffee in the common room. begrudgingly you admit to yourself, they’re really good at what they do. thank god you don’t belong to the same research group.
harsh but kind: brilliant researcher with high expectations of their students. will offer and make you tea as they grade your problem sets (with commentary) in front of you. after your semester in their class, you buy a bag of loose-leaf jasmine green tea because they got you hooked on it.
the politician: buddies with some higher-ups in university admin and the heads of other colleges. your peers derail class by bringing up current events. has a fixation on swords and genealogy. a bit of an anglophile. you took apart a transistor radio with them once. will make formal complaints to the math department on your behalf.
melancholy teaching professor: very cynical from a career in academia but here to have fun. one of the friendliest faces in the department. organizes the students and faculty to do outreach and lugs physics demos all around the tri-county area. talks to the undergrads like they are people. always kind of sad, it makes you wish you could fix all of the ills of academia for them.
