The smallest species of ray in the world is the finless sleeper ray, a species of electric ray. The smallest individual recorded was just 8.2cm (3.2in) long and weighed just 13g (0.46oz), potentially making it the smallest cartilagenous fish.
The finless sleeper ray gets its name from the fact, unlike other electric rays, it has no dorsal fin (the top fin).
This short story by Junji Ito is about a fault that appears in Amigara mountain after an earthquake. The earthquake exposes countless human-shaped holes in the mountain which seem to have been made about a thousand years ago. People, intrigued by these silhouettes, gather at the site and that’s when things get creepy.
It’s about a 15-20 min read, but if you haven’t read this before, you’re in for a treat. Link above.
i mean it’s not like i can just NOT reblog amigara fault. what if one of my followers is one of the lucky ten thousand who HASN’T been unutturably altered for life by it yet? go read it! it’s creepy, but trust me, it was made for you.
Why playing with algebraic and calculus concepts—rather than doing arithmetic drills—may be a better way to introduce children t
The familiar, hierarchical sequence of math instruction starts with counting, followed by addition and subtraction, then multiplication and division. The computational set expands to include bigger and bigger numbers, and at some point, fractions enter the picture, too. Then in early adolescence, students are introduced to patterns of numbers and letters, in the entirely new subject of algebra. A minority of students then wend their way through geometry, trigonometry and, finally, calculus, which is considered the pinnacle of high-school-level math.
But this progression actually “has nothing to do with how people think, how children grow and learn, or how mathematics is built,” says pioneering math educator and curriculum designer Maria Droujkova. She echoes a number of voices from around the world that want to revolutionize the way math is taught, bringing it more in line with these principles.
The current sequence is merely an entrenched historical accident that strips much of the fun out of what she describes as the “playful universe” of mathematics, with its more than 60 top-level disciplines, and its manifestations in everything from weaving to building, nature, music and art. Worse, the standard curriculum starts with arithmetic, which Droujkova says is much harder for young children than playful activities based on supposedly more advanced fields of mathematics.
“Calculations kids are forced to do are often so developmentally inappropriate, the experience amounts to torture,” she says. They also miss the essential point—that mathematics is fundamentally about patterns and structures, rather than “little manipulations of numbers,” as she puts it. It’s akin to budding filmmakers learning first about costumes, lighting and other technical aspects, rather than about crafting meaningful stories.
the thing about misogyny is that nothing makes apparent how prevalent it is faster than just pointing out misogyny, which will have people scuttering out of the damn sewers like ninja turtles to accuse you of being an overly sensitive shit-stirring know-nothing who's making up things to be offended about. which is actually also pretty misogynistic, but if you point it out people will come scuttering out of the damn sewers—

Maybe I have to savor cups of coffee, soak in the golden light of sunsets, get lost in the arms of my friends, in their laughter. Maybe I have to live in the moment and let the past go. Maybe I have to let go of the idea that there is anything in the world that fills the void, that gives me back all the things that I’m missing because there isn’t. I am only truly fulfilled when I am grateful for everything that I already have. Maybe I need people more than anything else. People who understand me. Maybe I have to feel the rain with every inch of my body. Maybe I have to memorise every kiss, every look into my eyes. Maybe I have to remember their eye colour and the way they said my name. Maybe those are the things that make me feel truly alive. Maybe it’s rainy days, maybe it’s listening to old songs that make me feel nostalgic. Maybe it’s days spent in bookshops and cafés. Maybe it’s buying fresh flowers. Maybe it’s hot cups of coffee early in the morning. Maybe it’s falling asleep to the sound of rain. Maybe it’s nothing I own, maybe it’s experiences, maybe it’s memories.
