SPONGEBOB WAS RIGHT!
is it not common knowledge that the creator of spongebob is also a marine biologist
Nope.

+3 to Intellect
If anybody’s wondering what’s happening here, this clip made it onto Outrageous Acts of Science, and they explained that this teacher was demonstrating the Leidenfrost effect, which is basically when you place a droplet of a liquid on a surface that’s far hotter than its boiling point. The part of the drop touching the hot surface turns into vapor and forms a cushion that the rest of the drop rests on top of, which causes it to skid across the floor so quickly. The substance the teacher uses in the video is liquid methane. But methane has a really low boiling point. Like, about −160 °C low. So once it touches the comparatively hot floor, the Leidenfrost effect comes into play, and it slides across the floor. The issue is though, methane is colorless, so you can’t normally see it. Thankfully (in this demonstration), methane is also very flammable, so he sets it on fire before dumping it onto the floor so you can see it as it moves. Definitely a cooler demonstration of the Leidenfrost effect than dropping a little water in a hot pan. Or hotter, if you like puns.

Are you sure?
These pictures make me so happy. They’re so full of unconditional love and family. That’s what family is about.
I really like the idea of an immortal being who loves memes
‘You’re 1008 years old why are you laughing so hard’
‘My friend, i have been alive countless human lifetimes and seen many things. I have seen the original production of hamlet, seen the king of rock himself perform, even rode horses with the king henry the 8th but i have never seen anything as entertaining as a surreal meme’
‘Wtf you’re like an ancient vampire and your favourite fucking joke is dat boi are you serious’

During the Bubonic Plague, doctors wore these bird-like masks to avoid becoming sick. They would fill the beaks with spices and rose petals, so they wouldn’t have to smell the rotting bodies.
A theory during the Bubonic Plague was that the plague was caused by evil spirits. To scare the spirits away, the masks were intentionally designed to be creepy.
Mission fucking accomplished
Okay so I love this but it doesn’t cover the half of why the design is awesome and actually borders on making sense.
It wasn’t just that they didn’t want to smell the infected and dead, they thought it was crucial to protecting themselves. They had no way of knowing about what actually caused the plague, and so one of the other theories was that the smell of the infected all by itself was evil and could transmit the plague. So not only would they fill their masks with aromatic herbs and flowers, they would also burn fires in public areas, so that the smell of the smoke would “clear the air”. This all related to the miasma theory of contagion, which was one of the major theories out there until the 19th century. And it makes sense, in a way. Plague victims smelled awful, and there’s a general correlation between horrible septic smells and getting horribly sick if you’re around what causes them for too long.
You can see now that we’ve got two different theories as to what caused the plague that were worked into the design. That’s because the whole thing was an attempt by the doctors to cover as many bases as they could think of, and we’re still not done.
The glass eyepieces. They were either darkened or red, not something you generally want to have to contend with when examining patients. But the plague might be spread by eye contact via the evil eye, so best to ward that off too.
The illustration shows a doctor holding a stick. This was an examination tool, that helped the doctors keep some distance between themselves and the infected. They already had gloves on, but the extra level of separation was apparently deemed necessary. You could even take a pulse with it. Or keep people the fuck away from you, which was apparently a documented use.
Finally, the robe. It’s not just to look fancy, the cloth was waxed, as were all of the rest of their clothes. What’s one of the properties of wax? Water-based fluids aren’t absorbed by it. This was the closest you could get to a sterile, fully protecting garment back then. Because at least one person along the line was smart enough to think “Gee, I’d really rather not have the stuff coming out of those weeping sores anywhere on my person”.
So between all of these there’s a real sense that a lot of real thought was put into making sure the doctors were protected, even if they couldn’t exactly be sure from what. They worked with what information they had. And frankly, it’s a great design given what was available! You limit exposure to aspirated liquids, limit exposure to contaminated liquids already present, you limit contact with the infected. You also don’t give fleas any really good place to hop onto. That’s actually useful.
Beyond that, there were contracts the doctors would sign before they even got near a patient. They were to be under quarantine themselves, they wouldn’t treat patients without a custodian monitoring them and helping when something had to be physically contacted, and they would not treat non-plague patients for the duration. There was an actual system in place by the time the plague doctors really became a thing to make sure they didn’t infect anyone either.
These guys were the product of the scientific process at work, and the scientific process made a bitchin’ proto-hazmat suit. And containment protocols!
reblogging for the sweet history lesson
Reblogging because of the History lesson and because the masks, the masks are cool
Humans, you all know historical medicine ain’t my Thang™, but if any of you have any interest about plague times or just want to understand these bitchin’ get ups, this post is for you!
What a great lesson :D
I’m screaming??? So my cat knows I get upset when he steps on my paintings (not yelling or anything I think he just sees me spend hours trying to cover up what his paws do) in my “studio” which is a crammed small storage closet with painting all over the floor drying , so like I’m in there rn and I saw him try to get to point A to point b but it was impossible for him to jump over so like he realized the matte parts were dry and like he was stepping on the corners of the painting and every step he’d look at his paw to see if he fucked up and honestly it was the most thoughtful thing ever I don’t ever wanna hear anyone ever say that cats don’t care
I beg you, if this ever happens again, get a video
An SR-71 Blackbird once flew from LA to Washington DC in 64 minutes. Average speed of the flight: 2145mph.
“There were a lot of things we couldn’t do in an SR-71, but we were the fastest guys on the block and loved reminding our fellow aviators of this fact. People often asked us if, because of this fact, it was fun to fly the jet. Fun would not be the first word I would use to describe flying this plane. Intense, maybe. Even cerebral. But there was one day in our Sled experience when we would have to say that it was pure fun to be the fastest guys out there, at least for a moment.
It occurred when Walt and I were flying our final training sortie. We needed 100 hours in the jet to complete our training and attain Mission Ready status. Somewhere over Colorado we had passed the century mark. We had made the turn in Arizona and the jet was performing flawlessly. My gauges were wired in the front seat and we were starting to feel pretty good about ourselves, not only because we would soon be flying real missions but because we had gained a great deal of confidence in the plane in the past ten months. Ripping across the barren deserts 80,000 feet below us, I could already see the coast of California from the Arizona border. I was, finally, after many humbling months of simulators and study, ahead of the jet.
I was beginning to feel a bit sorry for Walter in the back seat. There he was, with no really good view of the incredible sights before us, tasked with monitoring four different radios. This was good practice for him for when we began flying real missions, when a priority transmission from headquarters could be vital. It had been difficult, too, for me to relinquish control of the radios, as during my entire flying career I had controlled my own transmissions. But it was part of the division of duties in this plane and I had adjusted to it. I still insisted on talking on the radio while we were on the ground, however. Walt was so good at many things, but he couldn’t match my expertise at sounding smooth on the radios, a skill that had been honed sharply with years in fighter squadrons where the slightest radio miscue was grounds for beheading. He understood that and allowed me that luxury.
Just to get a sense of what Walt had to contend with, I pulled the radio toggle switches and monitored the frequencies along with him. The predominant radio chatter was from Los Angeles Center, far below us, controlling daily traffic in their sector. While they had us on their scope (albeit briefly), we were in uncontrolled airspace and normally would not talk to them unless we needed to descend into their airspace.
We listened as the shaky voice of a lone Cessna pilot asked Center for a readout of his ground speed. Center replied: “November Charlie 175, I’m showing you at ninety knots on the ground.”
Now the thing to understand about Center controllers, was that whether they were talking to a rookie pilot in a Cessna, or to Air Force One, they always spoke in the exact same, calm, deep, professional, tone that made one feel important. I referred to it as the “ Houston Center voice.” I have always felt that after years of seeing documentaries on this country’s space program and listening to the calm and distinct voice of the Houston controllers, that all other controllers since then wanted to sound like that, and that they basically did. And it didn’t matter what sector of the country we would be flying in, it always seemed like the same guy was talking. Over the years that tone of voice had become somewhat of a comforting sound to pilots everywhere. Conversely, over the years, pilots always wanted to ensure that, when transmitting, they sounded like Chuck Yeager, or at least like John Wayne. Better to die than sound bad on the radios.
Just moments after the Cessna’s inquiry, a Twin Beech piped up on frequency, in a rather superior tone, asking for his ground speed. “I have you at one hundred and twenty-five knots of ground speed.” Boy, I thought, the Beechcraft really must think he is dazzling his Cessna brethren. Then out of the blue, a navy F-18 pilot out of NAS Lemoore came up on frequency. You knew right away it was a Navy jock because he sounded very cool on the radios. “Center, Dusty 52 ground speed check”. Before Center could reply, I’m thinking to myself, hey, Dusty 52 has a ground speed indicator in that million-dollar cockpit, so why is he asking Center for a readout? Then I got it, ol’ Dusty here is making sure that every bug smasher from Mount Whitney to the Mojave knows what true speed is. He’s the fastest dude in the valley today, and he just wants everyone to know how much fun he is having in his new Hornet. And the reply, always with that same, calm, voice, with more distinct alliteration than emotion: “Dusty 52, Center, we have you at 620 on the ground.”
And I thought to myself, is this a ripe situation, or what? As my hand instinctively reached for the mic button, I had to remind myself that Walt was in control of the radios. Still, I thought, it must be done - in mere seconds we’ll be out of the sector and the opportunity will be lost. That Hornet must die, and die now. I thought about all of our Sim training and how important it was that we developed well as a crew and knew that to jump in on the radios now would destroy the integrity of all that we had worked toward becoming. I was torn.
Somewhere, 13 miles above Arizona, there was a pilot screaming inside his space helmet. Then, I heard it. The click of the mic button from the back seat. That was the very moment that I knew Walter and I had become a crew. Very professionally, and with no emotion, Walter spoke: “Los Angeles Center, Aspen 20, can you give us a ground speed check?” There was no hesitation, and the replay came as if was an everyday request. “Aspen 20, I show you at one thousand eight hundred and forty-two knots, across the ground.”
I think it was the forty-two knots that I liked the best, so accurate and proud was Center to deliver that information without hesitation, and you just knew he was smiling. But the precise point at which I knew that Walt and I were going to be really good friends for a long time was when he keyed the mic once again to say, in his most fighter-pilot-like voice: “Ah, Center, much thanks, we’re showing closer to nineteen hundred on the money.”
For a moment Walter was a god. And we finally heard a little crack in the armor of the Houston Center voice, when L.A. came back with, “Roger that Aspen, Your equipment is probably more accurate than ours. You boys have a good one.”
It all had lasted for just moments, but in that short, memorable sprint across the southwest, the Navy had been flamed, all mortal airplanes on freq were forced to bow before the King of Speed, and more importantly, Walter and I had crossed the threshold of being a crew. A fine day’s work.
We never heard another transmission on that frequency all the way to the coast.”

Always reblog passive-aggressive Blackbird speed check
guys seriously tho what the fuck even was the SR-71 blackbird. That plane is like someone made a fucking bet. Like someone went “I have ten bucks that says you can’t make something that cruises at Mach 2.5″ and the aero folks scoffed and went hold our collective goddamn beers and then they cracked out a plane that CRUISES AT MACH 3 (for reference the much vaunted “supercruise” of the F-22 is only a few ticks above Mach 1). You need to understand how patently absurd this fucking vehicle is from nose to tail. Its original iteration, the A-12, was the successor to the U-2 when it became clear the USSR had developed missiles that could fly high enough to shoot it down so instead they built a new plane so fast you couldn’t fucking hit it. THAT WAS LITERALLY HOW THE SR-71 WORKED. By the time you realized what was goddamn happening at 80,000 feet it was already out of your fucking timezone. One time a pilot missed a turn by a second and ended up over Atlanta instead of DC. It flew so fast and got so hot that the entire fuselage stretched by several inches midflight which turned out to be a gigantic pain because all the fuel lines were hooked up assuming this stretching factor, so while on the ground it leaked like a goddamn sieve so at one point they decided to combat this BY STUFFING IT FULL OF KOTEX literally they had to shove tampons in this incredibly sophisticated aircraft so the fuel would stay in. It was the first serious aircraft built entirely out of titanium because no other metal could do the job, and at the time titanium wasn’t a widely-used metal so the world’s only major supplier WAS THE ACTUAL USSR SO THE US ACTUALLY BOUGHT THE MATERIAL TO MAKE THEIR SECRET SPY PLANE FROM THE PEOPLE THEY WERE SPYING ON.
TL;DR Every single thing about this fucking aircraft is fucking ridiculous.

ok i need to talk about this in more than just tags. first of all this is beautiful. jake has such great character development. but we need to talk more about his relationship with amy and how he reacts to it. when amy says things, jake takes them to heart. she’s not doing it in a controlling way or “trying to change him” the way that trope is normally portrayed either. jake wants to grow up and be better. it’s not “ugh i have to drink 8 glasses of water a day now bc of my nagging girlfriend” or “i’m pretending to do this thing to get her off my back” he’s really trying. it’s an attitude of “my girlfriend is trying to take care of me and i want to grow and be better so i’m letting her”. and with the books, she doesn’t say “you’re an idiot you should read more” she makes a passing comment about it or mentions a book she loves and jake wants to love it too. they spend time together and feed off of each other in a natural way. (of course amy starts doing the cool cool cool cool thing… he says it a lot. it’s a contagious speech thing.) they really just know each other and it’s so wholesome and not the typical sitcom “ball and chain” type of thing.
sorry for the rant.

This is a summary of college only using two pictures; expensive as hell.
That’s my Sociology “book”. In fact what it is is a piece of paper with codes written on it to allow me to access an electronic version of a book. I was told by my professor that I could not buy any other paperback version, or use another code, so I was left with no option other than buying a piece of paper for over $200. Best part about all this is my professor wrote the books; there’s something hilariously sadistic about that. So I pretty much doled out $200 for a current edition of an online textbook that is no different than an older, paperback edition of the same book for $5; yeah, I checked. My mistake for listening to my professor.
This is why we download.

Spreading this shit like nutella because goddamn textbooks are so expensive.
not necessarily art related but as someone who couldn’t afford their textbooks this semester this is a godsend
REBLOGGING because after a little digging, I found my $200 textbook for free in PDF form.
friendly reminder that this exists since I know we’re all going back to college soon
Will reblog every time I see it.
