What I love about grace is that this is a man whose science nerd impulses outweigh his sense of self preservation and duty to Earth. You think if the rest of the crew had survived they'd be on board with putting everything aside to dedicate precious time to learning to communicate with the alien spider? Would they even be willing to follow through past first contact? The best part is that this could easily be treated as a fatal flaw but instead it is the key to his success.

I will never get over the fact that project hail mary is a story about a guy who goes from having no one - no family, no close friends, no one he has to tell when he gets forced onto an aircraft carrier in the middle of the ocean for several years, no one to mourn him when he is forced into a suicide mission, and perhaps most significantly, no one he is prepared to die for, to having one person who he is prepared to die for again and again and again.

You had to go lightyears across space to a different solar system and learn a new language you can't even speak unaided to find the platonic love of your life but when you did you burnt and starved and hurt for them without hesitation. Ryland Grace saves the world, but more importantly, he finds something bigger than himself to believe in and it's loving a lil alien crab dude.

Wonderful.

Hey All,

I've been away for some time, as we've been working really hard on something quite exciting:

let me present to you the world's first ever global ocean drainage basin map that shows all permanent and temporary water flows on the planet.

This is quite big news, as far as I know this has never been done before. There are hundreds of hours of work in it (with the data + manual work as well) and it's quite a relief that they are all finished now.

But what is an ocean drainage basin map, I hear most of you asking? A couple of years ago I tried to find a map that shows which ocean does each of the world's rivers end up in. I was a bit surprised to see there is no map like that, so I just decided I'll make it myself - as usual :) Well, after realizing all the technical difficulties, I wasn't so surprised any more that it didn't exist. So yeah, it was quite a challenge but I am very happy with the result.

In addition to the global map I've created a set of 43 maps for different countries, states and continents, four versions for each: maps with white and black background, and a version for both with coloured oceans (aka polygons). Here's the global map with polygons:

I know from experience that maps can be great conversation starters, and I aim to make maps that are visually striking and can effectively deliver a message. With these ocean drainage basin maps the most important part was to make them easily understandable, so after you have seen one, the others all become effortless to interpret as well. Let me know how I did, I really appreciate any and all kinds of feedback.

Here are a few more from the set, I hope you too learn something new from them. I certainly did, and I am a geographer.

The greatest surprise with Europe is that its biggest river is all grey, as the Volga flows into the Caspian sea, therefore its basin counts as endorheic.

An endorheic basin is one which never reaches the ocean, mostly because it dries out in desert areas or ends up in lakes with no outflow. The biggest endorheic basin is the Caspian’s, but the area of the Great Basin in the US is also a good example of endorheic basins.

I love how the green of the Atlantic Ocean tangles together in the middle.

No, the dividing line is not at Cape Town, unfortunately.

I know these two colours weren’t the best choice for colourblind people and I sincerely apologize for that. I’ve been planning to make colourblind-friendly versions of my maps for ages now – still not sure when I get there, but I want you to know that it’s just moved up on my todo-list. A lot further up.

Minnesota is quite crazy with all that blue, right? Some other US states that are equally mind-blowing: North Dakota, New Mexico, Colorado, Wyoming. You can check them all out here.

Yes, most of the Peruvian waters drain into the Atlantic Ocean. Here are the maps of Peru, if you want to take a closer look.

Asia is amazingly colourful with lots of endorheic basins in the middle areas: deserts, the Himalayas and the Caspian sea are to blame. Also note how the Indonesian islands of Java and Sumatra are divided.

I mentioned earlier that I also made white versions of all maps. Here’s Australia with its vast deserts. If you're wondering about the weird lines in the middle: that’s the Simpson desert with its famous parallel sand dunes.

North America with white background and colourful oceans looks pretty neat, I think.

Finally, I made the drainage basin maps of the individual oceans: The Atlantic, the Arctic, the Indian and the Pacific. The Arctic is my favourite one.

I really hope you like my new maps, and that they will become as popular as my river basin maps. Those have already helped dozens of environmental NGOs to illustrate their important messages all around the world. It would be nice if these maps too could find their purpose.

So the Temeraire series doesn’t do the Pern-derived magic/telepathic bond thing, and it’s nice to have some variety on that count since the telepathy thing is pretty widespread. But there’s this passage in crucible of gold that’s like—

Wait, my thriftbooks order arrived, let me go grab the quote

Or, Temeraire thought, he might as easily have gone alone--more easily, in fact; he had to carry Forthing cupped in his talons, and it was not at all convenient to always be looking to make sure he had not dropped out; Temeraire was not aware of him in quite the same way as of Laurence.

(Emphasis mine)

And this combined with the number of times it’s mentioned that (Russians aside) aviators just don’t seem to be capable of fearing their own dragons (and not just aviators who raised the dragons from the egg—it’s the same with inherited dragons) indicates to me that there’s something really interesting psychologically/biologically going on “under the hood,” there, so to speak.

And maybe this is just me and all those anthropology classes I took in college but that actually makes a lot of sense?

The historical record in the series dates the intentional breeding of dragons to a couple thousand years in the past, in china, but there’s a lot of evidence that there’s been a looser symbiotic relationship between humans and dragons a lot longer than that. Namely the domesticated elephants and the dragons in the Americas being the same species and of the same attitudes towards humans as dragons in Eurasia. So that’s likely at least 20 thousand years of symbiosis/mutual domestication, (if we assume they migrated together, which I do because it’s the simplest explanation) and it could well be much longer than that. That’s a long ass time. Like. The spread of IRL lactase persistence took less time than this.

And much like the benefits of being able to drink milk as an adult, the benefits of mutualism with an intelligent dinosaur-sized flying predator would absolutely have selective pressure on human populations. That’s just a given. I would talk about early hominins being third-tier scavengers here and Pleistocene megafauna and the canonical prevention of malaria via dragon proximity as compared to sickle cell anemia, but nobody wants me to regurgitate my entire biological anthropology 215 class in a tumblr post. Just trust me on this one.

Basically, the entire human species in the Temeraire universe will have been under a lot of positive selective pressure to be good symbiosis buddies to the dragons, so it’s no wonder aviator attachment is so intense.

This is likewise true for the dragons. A lot can be put down to intentional breeding in the last couple thousand years, but the foundation of dragons being prosocial with humans would have to be laid before then. Humans have domesticated predators IRL, but dragons are like 2-3 orders of magnitude larger than wolves and it took a long time to get dogs. The romans wouldn’t have had any luck if the dragons weren’t already partially on board. My theory is that this would have started way back. Australopithecus times, way back, because— [Anth 215 sneaks up behind me whilst the jaws theme plays] ANYWAY there’s a few benefits I can guess at for dragons having assistance hunting from small bands of persistence predators on occasion. I also think this would have intensified post-Pleistocene as the megafauna that would have been the dragons’ main prey went extinct and eventually agriculture would be the only way to replace— [Jaws theme intensifies] JUST TRUST ME BRO.

All this to say that humans being able to very quickly lose all instinctive fear of the dinosaur-sized flying predators they spend their time around and said predators developing not only attachment to humans but particular awareness of their humans specifically so as to prevent any possible accidental harm makes a lot of sense from an evolutionary biology perspective. It’s evidence of the same mutualistic relationship biologically shaping both species across the broader time spans that the series hints at.

September 15

This one is technically not yet history, because at the time of posting, the little craft has about half an hour left to go.  That said, let’s proceed.

In 2017, NASA’s Cassini space probe ended its twenty-year mission at Saturn.  After a nearly-seven-year-long journey there, it orbited the ringed planet for 13 years and just over two months, gathering copious amounts of information about the planet, said rings, and many of its moons.  It landed an ESA probe called Huygens on Titan, the first-ever soft landing in the outer Solar System.  It discovered lakes, seas, and rivers of methane on Titan, geysers of water erupting from Enceladus (and passed within 50 miles of that moon’s surface), and found gigantic, raging hurricanes at both of Saturn’s poles.  

And the images it returned are beautiful enough to make you weep.

On this day in 2017, with the fuel for Cassini’s directional thrusters running low, the probe was de-orbited into the Saturnian atmosphere to prevent any possibility of any contamination of possible biotic environments on Titan or Enceladus.  The remaining thruster fuel was used to keep the radio dish pointed towards Earth so the probe could transmit information about the upper atmosphere of Saturn while it was burning up due to atmospheric friction.

This is us at our best.  We spent no small amount of money on a nuclear-powered robot, launched into space, sent it a billion miles away, and worked with it for two decades just to learn about another planet.  And when the repeatedly-extended missions were through, we made the little craft sacrifice itself like a samurai, performing its duty as long as it could while it became a shooting star in the Saturnian sky.

if you're from the USA, tag what you chose and what general region you're from (don't dox yourself, I don't need to know your hometown or any other security questions), using this map:

I'd also love to know if you were aware of the opposing connotation/definition or any of the various other pronunciations before reading this. I am not the least bit interested in what anyone thinks is ~correct~, only what they use and what they've heard before.

for non-USAmericans, I'm super curious if this linguistic difference exists outside the USA in any way, so I'd love it if you tagged your country as well.

reblog for sample size, you know the drill.

How many times can I stitch variations on colour wheels? At least a few more, anyway. My own design.

This is the second piece I've done that blends contrasting colours in blackwork, and I'm learning to trust the process. In both cases, it looked horribly messy while I was stitching, but then when it was finished and I could step back to look at it, I could finally see the gradient effect I was going for.
