I was thinking the other day about we tend to scroll and look idly between things online. I’m wondering if we do that as a foraging instinct, looking for the ripest of content, instead of food. I’m not an evolutionary biologist though, so instead I’m throwing this into the void hoping that Science Tumblr answers

Anyone got fun sci-fi recs? Emphasis on Fun.
Murderbot are my comfort books and I loved The Long Way to a Small Angry Planet. That's really the ideal vein that I'm looking for. I've read some Scalzi books and enjoyed them and same with the Martian, but beyond that I'm still pretty fresh to sci fi. I'm a big fantasy person, so I'd appreciate any and all ideas of what I can explore next. Thanks!!!

Okay it's finally done.
Hello, people of Tumblr! Please, please spread this survey. Send it to your kids, your classmates, your niblings. Help me out here. I need people who did their GCSEs in 2022 in England to do this survey on the impact of COVID on GCSE results. It's for my EPQ. I need 100 respondents. Please, Tumblr... The fate of my grade rests in your hands.
Here is the survey: https://forms.office.com/e/tYkks2UfHe
Also, if you got this far, here's some GIFs from superwholock below the cut.
Also, I know y'all like polls, so here.
Listen: Sam Winchester may not have been able to complete his education, but he'd want someone else to complete theirs and do well, so do this for him:
Tumblr media
And for you Lockers? You know your guy Sherlock is smart and autistic, like me. He'd want another smart autistic person to succeed and get into a good uni (did I mention this EPQ is my big grab for a top university?). Then I can become a top detective or whatever idk I didn't watch the show I'm sorry but if you do this survey and tell me you're a Sherlock fan who saw this in the tags then I swear, I'll watch it. For you. And my grade. Please.
Tumblr media
Finally, doctor who, my beloved fandom. I love you all so much- well, maybe not all of you, but I appreciate the fandom as a whole for everything you've done for me. The word count of ff I've contributed to this fandom (AO3: z_in_a_blue_box for proof) should tell you all how much I love this show. Here, have gay people, and go do my survey. Please. I'm begging you.
The Doctor would say to always help people when you can. This can be your kind act of the day. "Always try to be nice, never fail to be kind". Please.
Tumblr media
Thank you, fandoms of Tumblr. I appreciate you all.

ok this is super irrelevant but
this was just a thought floating in my head bc i’m writing a Hanahaki au in a relatively modern setting and started thinking, “so what would this disease fall under if you were to study it?”

Yay - I get to share my love for tidbit Hazbin lore while sharing knowledge that makes me look like a millennial boomer XD ahem... Alastor, our favorite overlord, for all intents and purposes, is a fucking elemental. His abilities are absolutely terrifying from a scientific standpoint. Okay, so remember how during the "Stayed Gone" number, Vox starts glitching out and "loses his signal" - and then the Pride ring subsequently has a blackout? That is entirely Alastor's (or whatever the fuck is benefactoring him) doing. Radio can do that. No horseshoe magnet required. IRL stuff. Despite being digital enough to render a bluescreen when compromised, Vox may still have older hardware from his former days as a rabbit-eared, thick cathode-ray tube.
Tumblr media
And Alastor is our radio demon. Keep this in mind. IRL, once upon a time, during the 1940s - before digital television - there was no "Channel 1". That's because in the US, a very long time ago, both radio and TV shared the band that we call "Channel One":
"Until 1948, Land Mobile Radio and television broadcasters shared the same frequencies, which caused interference. This shared allocation was eventually found to be unworkable, so the FCC reallocated the Channel 1 frequencies for public safety and land mobile use and assigned TV channels 2–13 exclusively to broadcasters. Aside from the shared frequency issue, this part of the VHF band was (and to some extent still is) prone to higher levels of radio-frequency interference (RFI) than even Channel 2 (System M)." (https://en.wikipedia.org/wiki/Channel_1_(North_American_TV))
Then for a short stint, Channel One was exclusively reserved for radio:
Channel 1 was allocated at 44–50 MHz between 1937 and 1940. Visual and aural carrier frequencies within the channel fluctuated with changes in overall TV broadcast standards prior to the establishment of permanent standards by the National Television Systems Committee. In 1940, the FCC reassigned 42–50 MHz to the FM broadcast band. Television's channel 1 frequency range was moved to 50–56 MHz. Experimental television stations in New York, Chicago, and Los Angeles were affected. (https://en.wikipedia.org/wiki/Channel_1_(North_American_TV))
Every local TV channel and radio station has a frequency range on the electromagnetic spectrum. For those who still listen to radio on non-internet-reliant radios devices, those funny little numbers next to a station's name are a ballpark number for the frequency the station broadcasts in the Hertz unit. A Hertz (Hz) is one wave per second. A KiloHertz (KHz) is 1,000 waves per second. A GigaHertz (GHz) is 1 billion waves per second. Modern AM radio stations are 535-1605 kHz Modern FM radio stations are 88-108 MHz  TV VHF Channels 2 thru 13 are 54-216 MHz TV UHF Channels 14 thru 36 are 470-608 MHz And no, that's not a discrepancy between VHF and FM radio: the frequencies designated for FM radio are nestled right in there with TV ones. FM radio is between Channels 6 and 7.
Tumblr media
(chart from http://hyperphysics.phy-astr.gsu.edu/hbase/Audio/radio.html) Even today, radio and TV are slightly shuffled in there in regards to designated frequencies. That implies that depending on Alastor's band of preference, Vox could theoretically hear Alastor's broadcasts of screaming victims without an actual radio nearby. This would be especially true if Vox still has some of his older hardware. In fact, in older televisions where a knob is used to change channels, much of the static you'd hear in-between channels is actually background radiation from deep space - along with any interference from man-made sources. No wonder Vox is obsessed with Alastor. Alastor can torment him in an in-between realm-channel like Freddy Kruger.
Tumblr media
Yet, if radio signals were only a Vox problem, why did nearly every light and electronic device go out in the Pride except the emergency lights at the Heaven embassy?
Tumblr media Tumblr media Tumblr media Tumblr media
It might depend on how we define the word "radio". Is it radio, as in "those radio stations we can listen to without the internet"? Maybe radio, as in any frequency utilized in modern communications, including TV and Radio? Or is it radio, as in "almost any signal on the electromagnetic spectrum with a frequency lower than friggin' heat?" People, below is an over-simplified chart of the electromagnetic spectrum and usages.
Tumblr media
When radio is defined as a specific part of the electromagnetic spectrum, it is literally any frequency below infrared. *** Cellphone service and WiFi use radio signals within this range. Most cellular services are between 600 MHz and 39 GHz WiFi routers are about 2.4-5 GHz (6 GHz in newer models)  That's where the "G" in "4G" and "5G" come from - the "G" stands for "Gigahertz" Radio, local television, cellphone service, WiFi, and basically any point in the internet that isn't linked by a landline - these are all safely within the part of the electromagnetic spectrum that the scientists would call "radio". If Hell's technology mirrors the real world, all electronic devices need radio frequencies in order to communicate. The VVV's empire is truly fucked, should Alastor so choose. The only plot hole I'm seeing in this explanation is why all the lights went out. These devices don't run on radio - they communicate using it. My best-educated guess is that the on/off switch for Hell's power grid is on an open network and at least part of it wireless. Or maybe Alastor's radio attack work like general EMP and just breaks stuff. I'm not an expert on these sorts of things. I politely ask that someone in the comments, please enlighten me U.U ------------------------------------- Also, when taking screenshots, I realized that Cannibal Town and the Heaven Embassy were the only places with lights on during the blackout.
Tumblr media
is that...?
Tumblr media
Cannibal Town?
Tumblr media
If this is, in fact, Cannibal Town, then my only guess is that the Cannibals are so hipster, that most of them light their homes and businesses with candlelight and leviathan whale oil. Neither of which rely on wifi. Only some of their region's light was lost in the blackout. They might use some electricity, but they don't rely on it. This suggests that Alastors friendship with Rosie might be less of an organic friendship and more like a strategically slick alliance. Rosie's territory is one part of Pride that Alastor can't completely shut down (other than the Embassy). But, who knows?
Tumblr media
Alastor's derision of modern tech now seems to have more merit than just being "hipster" or avoiding a digital footprint (which I used head-canon). Alastor can literally just shut that crap down. This might also suggest why Alastor is homies with Zestial - another old-timey prick.
Tumblr media
Alastor makes alliances with demons he can't easily overpower with his abilities. This might look self-contradictory considering Alastor felt comfortable teasing Lucifer - until you realize Alastor did so only after he knew angels could be killed. (And yes, I know what I wrote about Alastor a couple of notes back with the "popsicle" evaluation. I don't consider flip-flopping a moral issue if done so by epiphany. That one stays, because it's funny XD ) ----------------------- Another theory! Ok, so this theory isn't entirely my own-own, I'm just building off of it based on what I've said (mostly Roo stuff). So, IRL scientists decided to take an image of the observable universe in the microwave range. Microwave energy is in the upper ends of radio, but just below infrared in frequency. What they found was cosmic background radiation - a lot of energy which isn't coming from the stars themselves.
Tumblr media
(Image source: https://www.space.com/33892-cosmic-microwave-background.html) Some scientists theorize this is because this particular energy is left over from the formation of the universe. So about Roo:
In the first non-pilot episode, The Story of Hell as read by Charlie, states that the angels of pure light "worshipped good and shielded all from evil." During this line, imagery of two faces are shown before the angels: one face of light and another face of twisted red and black.
Tumblr media
Subsequent lines and imagery in the episode suggest that this "evil" existed before Lucifer fell or Eve allowed this evil to enter the world - even before the Earth was created. Some Tumblrs who have been in this fandom longer than I have will know of Roo, a character that appears in VivziePop's older works. Some of Roo's monikers include "The Root of All Evil" and the "Tree of Knowledge". I'm wondering if in the Hellaverse, cosmic background radiation of the universe is a manifestation of Roo when she isn't bound to a tree. Did Alastor bite the apple the second third time for mankind? XD
------------------------------------------------- While researching for this paper, I learned that microwave ovens and 2G cell phones operate within the same frequencies at around 2 GHz. Apparently, the only reason the cell phone doesn't cook your brain is because the wattage is too low. I dunno what that means. I'm not a scientist. But now, Alastors singing lines in S1E8 have me thinking: "The constraints of my deal surely have a back door  Once I figure out how to unclip my wings,  guess who will be pulling all the strings" Knowing what Alastor's abilities are capable of, this has me wondering whether Alastor is being empowered by one cosmic entity, while being chained by someone else entirely. Someone might have gone out of their way to get Alastor into a contract, if only to keep him from cooking the universe for his viewing pleasure... on a glass plate.
Tumblr media
Cooking souls in microwaves would require that they be at least partially made of water, however. Buuuut... I guess if there are working ACs in Hell, I really shouldn't read too much into it XD -------------
Do you think the mad scientists from Helluva Boss ever chat over coffee about the abilities of the overlords based on casual observation? Then one time, Alastor's name comes up... ...and after four minutes, they're both just like "Nope"?
{END} *** Note: Googling "Electromagnetic Spectrum charts" will yield different results. Some charts will have different designations frequencies lower than radio, like Extremely Low Frequencies (ELF). I do not know whether this difference is a reflection of a newer categorization, or if most charts online are made for laymen such as myself. Most charts I saw years ago only designated "radio" as "everything below microwave". I want to assume that the "only radio below microwave" categorization went into the writer's designing of Alastor's character simply because it is more common while making for a more interesting power scaling.
______________ Disclaimer: I am composed of chauffeur knowledge. I know nearly nothing about communication science little about radiation stuff. I just took an astronomy elective once, so I sorta knew where to look. I have no idea what the fuck I'm talking about. I know that I confused frequency and wavelength somewhere. Please, #sciencesideoftumblr feel free to correct me. ----------------- TLDR: Most tech IRL use radio waves to communicate. That Includes TVs, WiFi and cell phones. Radio Demon can make the Pride Ring go kaploowee just looking at it funny.

i think i officially set my sights on a therapist and i'll be contacting her very soon?? therapy was legitimately not on my 2024 bingo card (or in the cards for me at all) but here we are????
#this blog always had a focus on social science and detangling feelings and experiences. like it's basically been serving as my diary#bc this blog has always been my main outlet for it. i hate talking feelings to anyone irl. it's a bad habit but i hate it#so it was a game changer and helped me grow up sooo much. esp supplemented w other people's experiences.#being raised by a stoic engineer mother who's very much warm but also not very good at feelings at times has caused me to suppress SO much#compounded w being the eldest daughter. like that is a damning sentence in and of itself#tumblr just gave me an outlet for stuff like this. and every social media is essentially a highlight reel of ppl's best moments.#tumblr is the opposite. i've always loved that too whether it was in the form of humor or more earnest posts#could i work through my own issues by myself? yes probably#and my blog will always have that facet even if i get a therapist#but a therapist's input. just a professional's input. will expedite a lot of improvement for me i think#this has been a critical time period for me anyway bc i'm budgeting my whole schedule for once vs being handheld by uni deadlines#and it's just gonna keep getting more and more intense from here bc i'm truly pushing my comfort zone more than ever before#it just feels like the right call even tho i'm lowkey nervous ab it bc i HATE talking feelings in person.#this therapist will not fall for my trying to deflect by asking her about her life. which. usually works on my friends <3#we will see. a therapy arc is coming very soon basically#p

Ch. 13 "Rebirth"
Tumblr media
This is fanart of Cave Johnson from the lovely @sciencewife's "Schrödinger's Cave" !
I couldn't stop thinking about the newest chapter and I just had to start drawing this scene.
-- closeup of Cave below the cut --
Tumblr media
(sorry if anything is blurry, click on it and it should be better)
Not gonna lie, this is probably the best drawing of light effects I have done so far, I am very happy with this! although I'm not sure about the rest of the drawing (it feels almost too cluttered)
btw cave's eyes are static. but it doesn't show up very well
(side notes: I tried doing some other effects but I couldn't get the plugin in krita to work. I also planned to have a glitched out cave with the jumpsuit and portal gun looking angry but I felt it wouldn't fit without it being confusing. Still have the drawing tho)

SCIENCE SIDE OF TUMBLR PLEASE TELL ME THINGS ABOUT COPPER
I'm creating an OC that is made of copper, so they can absorb energy and redirect it but stronger, and they rust as a weakness, but I don't know much else about how copper works, so I'd like some help plz.
