Hello new followers! I’m Ritter. If you found me through my fiction and would like to see more of it, there’s more of that under the tag #fiction i guess. my spur-of-the-moment variable-quality writing is under #latefic. I also occasionally write non-fiction, although that is regrettably not tagged (though my better half @togglesbloggle usually reblogs them and has a more searchable blog).

My current long-term writing project is a modern translation of the Loom of Hours, a collection of meta-fables which have their origin in oral folklore from a world not quite our own. For this translation, I’ve chosen the style of Borges and Dunsany, for reasons which should be obvious when you read it.  As of 18 May 2023, seven out of sixteen stories are more or less in presentable shape, not including a foreword to go along with the finished reader. (As of December 6, all stories are now on AO3, including an all-new entry for Glass!)

As for this blog: I tend to reblog stuff I like (which is often but not limited to: cute dogs and cute boys), and stuff I find cool (including Art and Science and History). I’m a classical musician by trade, so I will sometimes shitpost about music, and even talk about it if I’m in the mood.

Thanks for your interest! Have a great day ^_^

The answer is 1, why is everyone a delinquent?

Y'all please, learn your pemdas (or bodmas or whatever you learned it as)

It's 16

*sigh*

Parentheses equation is 2+2, which is 4.

Now we multiply by 2 to get 4x2 which is 8

8 DIVIDED BY 8 is 1.

I have no fucking clue how you can get 16 out of this. I don’t think you’re bad at math, I think you just need glasses.

It’s 1.

It’s 16.

8 / 2 * (2+2) = 

8/2 * (4) = 

4*4 = 16

You do the parentheses, then you go left to right.

That isn’t how this works.....

PEMDAS

8/2*(2+2) (P = Parentheses)

8/2*(4) (M = Multiply)

8/8=1 (D = Division)

@kingoftartesoss​

Use Mathpapa calculator if you still don’t believe me.

No, Riley.

M isn't in the original problem but 8÷2 still needs a resolution. You have to solve 8÷2 as-is after (2+2) no matter what.

So you're not following PEMDAS by factoring x4 into 8÷2.

It's literally this simple.

I, uh, I think it’s 1, actually.

Plug it into a searchbar, or a scientific calculator that waits until the whole thing is input & that's the answer.

1

No need.

Everyone on this post:

@nonanalogue can you solve this for us because I swear to goodness the answer is 1 but this post is making me doubt my brains

Happily!

So the problem is two-fold: first, order of operations as most people are taught it is a lie, and second, the original problem is written very ambiguously.

Let’s drill down into that first point.

PEMDAS! Parentheses, exponents, multiplication, division, addition, subtraction. Everyone’s taught to do operations in that order! Except that’s not really right. As a math teacher of mine put it, “it works for now, but you’ll find out I was lying in a few years.”

The problem is that multiplication and division are the same operation, and addition and subtraction are also the same operation. Division is really just multiplying by a fraction, and subtraction is just adding a negative. With that in mind, it doesn’t necessarily make sense to do some multiplication arbitrarily early in the problem before the rest! As a result, here’s the bottom line for that point:

Both 1 and 16 are right.

How can that be?

Well, that brings me to the second point: the expression is written very ambiguously, so as to maximize confusion! It’s also why I don’t like using the division symbol when a fraction will do just nicely.

Observe two other ways we could write this expression:

The first one resolves to 8/8, which is 1. The second resolves to 4(4), which is 16. Both are right, only because the original expression is vague.

The sad thing is that everyone hates fractions, when actually they make life so much nicer!

I will never get over how brilliant this comic is. The artist could have just drawn a single image in response, but instead we have this masterpiece. The world doesn’t deserve @iguanamouth.

In a monumental discovery for paleontology and the first of its kind "Mummy of a juvenile sabre-toothed cat Homotherium latidens from the Upper Pleistocene of Siberia"

Abstract The frozen mummy of the large felid cub was found in the Upper Pleistocene permafrost on the Badyarikha River (Indigirka River basin) in the northeast of Yakutia, Russia. The study of the specimen appearance showed its significant differences from a modern lion cub of similar age (three weeks) in the unusual shape of the muzzle with a large mouth opening and small ears, the very massive neck region, the elongated forelimbs, and the dark coat color. Tomographic analysis of the mummy skull revealed the features characteristic of Machairodontinae and of the genus Homotherium. For the first time in the history of paleontology, the appearance of an extinct mammal that has no analogues in the modern fauna has been studied. For more read here: https://www.nature.com/articles/s41598-024-79546-1

I always knew it was possible, but I never dared to hope.

OH MY GOSH OH MY GOSH OH MY GOSH OH MY GOSH OH MY GOSH OH MY GOSH OH MY GOSH OH MY GOSH LOOK AT THIS WE HAVE A SABERCAT MUMMY AAAAAAA

We now have concrete evidence for what saber-toothed kittens (well, at least one species) looked like in real life, and that can in turn help inform what the adults looked like!

To summarize the main points from the paper:

  1. Seems like they were dark brown, with longer fur on the neck and back than on the legs; some of the photos make the mummy look almost shaggy. I don't see any obvious spots or other patterning, but the muzzle and paws look to be a little lighter in colour.
  2. They had what seems to be a "moustache" of longer fur at the corners of their mouth (Or maybe "sideburns", more like a lynx; it's hard to tell from the photos, and the paper just says "In the region of the mouth corner, the hair is significantly elongated". It also looks to me like there's a bit of a beard going on in the chin region, but I can't say for sure).
  3. The ears were small and round, as would be expected from an animal from a cold climate. The nose was typically feline, but the upper lips were more than twice as long as a lion's, proportionally; maybe there's something to the "bulldog" hypothesis after all.
  4. The paws are short and rounded, with no carpal pad (wrist bean). The paper doesn't bring it up (and it might just be an artifact of preservation) but in the figure the toe beans look like they're covered in fur, like a lynx? I could be wrong, though. In any case, the shape and structure of the foot look like adaptations to walking on snow.
  5. Everything else about its proportions and muscle distribution was about what you'd expect based on the skeletons of the adults; powerfully built neck and arms,

In conclusion, this is the most exciting thing I've seen all year and I NEED to find the time to draw a mama Homotherium caring for her babies in the middle of winter

The thai for “5″ is pronounced roughly “Ha”, and so where english internets would generally put “lol” or something, they put “555555555″.

I was looking for this post for so long

I have come into possession of an ornithology book from the 1930's and they had such a way of describing birds back then, modern publishers of birding booking should take note! Here are some of the bangers.

yes, this book refers to the anhinga as a water-turkey

biologists will be like this is a very simplified diagram of a mammalian cell

chemists will be like this is a molecule

okay but this is what the best render of a human cell looks like

They are not kidding

We are full of so many fuckign guys

This is actually a full on interactive map! You can put your cursor over any structure to focus on it and see its name, you can focus on all the structures that are part of a specific pathway and, when you click on proteins, you open it up on PhosphoSitePlus, which is a curated database of proteins and their post-translational modifications. It has a helpful description and summary for each protein!

This is a HUGE complementary resource for learning molecular biology! It really helps to make sense of each individual pathway and it puts everything into perspective. It only focuses on human, rat and certain other animal cells, so it won’t have all the pathways one would wish to see… But for the pathways it does include, consider opening the image and accompanying it as you learn or revise them!

oh wow, thank you for the additional information, i had no idea, that’s so much cooler than just the flat picture.
