Romanticizing studying/education

While I am not currently enrolled in college, something I found incredibly helpful when it came to studying and taking notes was fully romanticizing it. And by that I mean going all the way in— I would put on a classical music playlist and set my LEDs to a warm orange tone and pretend I was a young scholar in ye olden days studying by candlelight, and a couple hours later I’d have half a notebook filled with color-coded notes. Another time I put on some film noir jazz and rain ambience and imagined I was a tired, grizzled detective working tirelessly on a cold case that just wasn’t making sense. And sure enough, I would have pages upon pages of notes and work completed by the end of the night. It sounds really silly but I shocked myself with how well it worked, and I wanted to share my experience with it in case it can help anyone else!

What We Learned from Flying a Helicopter on Mars

The Ingenuity Mars Helicopter made history – not only as the first aircraft to perform powered, controlled flight on another world – but also for exceeding expectations, pushing the limits, and setting the stage for future NASA aerial exploration of other worlds.

Built as a technology demonstration designed to perform up to five experimental test flights over 30 days, Ingenuity performed flight operations from the Martian surface for almost three years. The helicopter ended its mission on Jan. 25, 2024, after sustaining damage to its rotor blades during its 72nd flight.

So, what did we learn from this small but mighty helicopter?

We can fly rotorcraft in the thin atmosphere of other planets.

Ingenuity proved that powered, controlled flight is possible on other worlds when it took to the Martian skies for the first time on April 19, 2021.

Flying on planets like Mars is no easy feat: The Red Planet has a significantly lower gravity – one-third that of Earth’s – and an extremely thin atmosphere, with only 1% the pressure at the surface compared to our planet. This means there are relatively few air molecules with which Ingenuity’s two 4-foot-wide (1.2-meter-wide) rotor blades can interact to achieve flight.

Ingenuity performed several flights dedicated to understanding key aerodynamic effects and how they interact with the structure and control system of the helicopter, providing us with a treasure-trove of data on how aircraft fly in the Martian atmosphere.

Now, we can use this knowledge to directly improve performance and reduce risk on future planetary aerial vehicles.

Creative solutions and “ingenuity” kept the helicopter flying longer than expected.

Over an extended mission that lasted for almost 1,000 Martian days (more than 33 times longer than originally planned), Ingenuity was upgraded with the ability to autonomously choose landing sites in treacherous terrain, dealt with a dead sensor, dusted itself off after dust storms, operated from 48 different airfields, performed three emergency landings, and survived a frigid Martian winter.

Fun fact: To keep costs low, the helicopter contained many off-the-shelf-commercial parts from the smartphone industry - parts that had never been tested in deep space. Those parts also surpassed expectations, proving durable throughout Ingenuity’s extended mission, and can inform future budget-conscious hardware solutions.

There is value in adding an aerial dimension to interplanetary surface missions.

Ingenuity traveled to Mars on the belly of the Perseverance rover, which served as the communications relay for Ingenuity and, therefore, was its constant companion. The helicopter also proved itself a helpful scout to the rover.

After its initial five flights in 2021, Ingenuity transitioned to an “operations demonstration,” serving as Perseverance’s eyes in the sky as it scouted science targets, potential rover routes, and inaccessible features, while also capturing stereo images for digital elevation maps.

Airborne assets like Ingenuity unlock a new dimension of exploration on Mars that we did not yet have – providing more pixels per meter of resolution for imaging than an orbiter and exploring locations a rover cannot reach.

Tech demos can pay off big time.

Ingenuity was flown as a technology demonstration payload on the Mars 2020 mission, and was a high risk, high reward, low-cost endeavor that paid off big. The data collected by the helicopter will be analyzed for years to come and will benefit future Mars and other planetary missions.

Just as the Sojourner rover led to the MER-class (Spirit and Opportunity) rovers, and the MSL-class (Curiosity and Perseverance) rovers, the team believes Ingenuity’s success will lead to future fleets of aircraft at Mars.

In general, NASA’s Technology Demonstration Missions test and advance new technologies, and then transition those capabilities to NASA missions, industry, and other government agencies. Chosen technologies are thoroughly ground- and flight-tested in relevant operating environments — reducing risks to future flight missions, gaining operational heritage and continuing NASA’s long history as a technological leader.

You can fall in love with robots on another planet.

Following in the tracks of beloved Martian rovers, the Ingenuity Mars Helicopter built up a worldwide fanbase. The Ingenuity team and public awaited every single flight with anticipation, awe, humor, and hope.

i could never associate myself with any other form of academic aesthetics than chaotic academia. this is literally the only 'aesthetic' i can abide by, because why are there so many books scattered on my bed, i sleep alone on a whole queen size bed but cannot fit in because after a whole day of studying,books.are.everywhere.

and for some odd reason i refuse to arrange them, it somehow makes it harder for me to find them so i just don't, i have the tendency to make the most important notes on scraps of paper??? though i end up collecting all of them and now i have a stash of notes only i can understand because they are so damn context less.

i always wanted to associate myself to dark academia, because omg i wanna be mysterious so bad, but omfg when i start speaking :D there's literally no stopping me.

my hands, ALWAYS STAINED WITH INK, like i'm EMBARASSED so so embarassed, that i'm a legal adult with pen stains on my clothes, blankets, pillow covers, body and what not.

it is not as pretty or put together as it seems when you study, but it's fun, there's fun in learning i literally just had a mental breakdown over physics but it's a privilege, a privilege that the only thing i'm stressing over is acads, we should probably enjoy the process of learning more than raving over the outcomes, hopefully that makes the process more enjoyable and well, easier to an extent.

anyway, it's 5:20 PM and am off for a nap, b-bye :3

On National Poop Day, we share ancient poop! Can you guess which animal made this well-preserved mess? A giant ground sloth! This specimen was found in Mylodon Cave in Chile. Bones of giant ground sloths have been found near those of early humans, hinting that ground sloths and early humans used the same caves, though not necessarily at the same time.

look, I know I've talked about this essay (?) before but like,

If you ever needed a good demonstration of the quote "Any sufficiently advanced technology is indistinguishable from magic", have I got an exercise for you.

Somebody made a small article explaining the basics of atomic theory but it's written in Anglish. Anglish is basically a made-up version of English where they remove any elements (words, prefixes, etc) that were originally borrowed from romance languages like french and latin, as well as greek and other foreign loanwords, keeping only those of germanic origin.

What happens is an english which is for the most part intelligible, but since a lot everyday english, and especially the scientific vocabulary, has has heavy latin and greek influence, they have to make up new words from the existing germanic-english vocabulary. For me it kind of reads super viking-ey.

Anyway when you read this article on atomic theory, in Anglish called Uncleftish Beholding, you get this text which kind of reads like a fantasy novel. Like in my mind it feels like it recontextualizes advanced scientific concepts to explain it to a viking audience from ancient times.

Even though you're familiar with the scientific ideas, because it bypasses the normal language we use for these concepts, you get a chance to examine these ideas as if you were a visitor from another civilization - and guess what, it does feel like it's about magic. It has a mythical quality to it, like it feels like a book about magic written during viking times. For me this has the same vibe as reading deep magic lore from a Robert Jordan book.

Y'all, the world is sleeping on what NASA just pulled off with Voyager 1

The probe has been sending gibberish science data back to Earth, and scientists feared it was just the probe finally dying. You know, after working for 50 GODDAMN YEARS and LEAVING THE GODDAMN SOLAR SYSTEM and STILL CHURNING OUT GODDAMN DATA.

So they analyzed the gibberish and realized that in it was a total readout of EVERYTHING ON THE PROBE. Data, the programming, hardware specs and status, everything. They realized that one of the chips was malfunctioning.

So what do you do when your probe is 22 Billion km away and needs a fix? Why, you just REPROGRAM THAT ENTIRE GODDAMN THING. Told it to avoid the bad chip, store the data elsewhere.

Sent the new code on April 18th. Got a response on April 20th - yeah, it's so far away that it took that long just to transmit.

And the probe is working again.

From a programmer's perspective, that may be the most fucking impressive thing I have ever heard.

NASA Data Sonification: Black Hole Remix

In this sonification of Perseus. the sound waves astronomers previously identified were extracted and made audible for the first time. The sound waves were extracted outward from the center. (source)

I find this Antonov An-74 plane hilarious. Not just because of the weird engine placement, everyone finds that hilarious. This (and the related AN-72) are nicknamed "Cheburashka", after this cartoon character:

But no, the even funnier thing, to me, is how they've labeled this plane. Lemme zoom in:

THEY PUT THE PLANE'S FAX NUMBER ON IT

who sees a fucking plane and goes "hey, maybe I should send that plane a fax"?
