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!

I can’t stop laughing at Harry running the fuck awaythe boy who lived ladies and gentlemen.

….You realize, of course, that Hermione Granger lit a teacher on fire when she was eleven, and kept a person alive in a jar for a year when she was fourteen, and studies dark and forbidden magics for kicks, and is one of the brightest and strongest witches of her era. If she came at me, even wandless, I would aparate to Neptune to get away from her.

Hermione Granger also: 

  • punched Draco Malfoy in the nose for being an idiot 
  • purposefully performed a confundus charm on whatshsface WHILE HE WAS FLYING just so Ron would win (omfg that is so fucking dangerous) 
  • literally pulled a fucking Bourne Identity on her parents and managed to set them up in fucking Australia (jesus christ she literally made it so that she NEVER EXISTED wtf that’s so fucking 007)
  • Convinced the Ministry of Magic to give her an incredibly dangerous and volatile device that allowed her to ALTER TIMELINES COMPLETELY (just because she was so smart, literally, that is the reason, her “potential”) 
  • Has enough basic survival skills and badass magic to literally disappear to the middle of nowhere and flourish AND figure out Voldemort’s plot with Harry 
  • Hermione also figures out not only what Voldemort’s plan is, but generally how to beat it, WAY BEFORE VOLDEMORT EVER DOES. Why? because she is just that much smarter and better at magic than everybody else

in conclusion: Voldemort wishes he could be as awesome as Hermione, that’s why he wants to kill her so bad. 

Can we rehave this series with hermione as the protagonist.

Hey Shychemist. I've been following your blog for awhile and I want to bring up something that seems dated but nonetheless holds to be accurate today. I feel like the girls who consider themselves to be on the science side of tumblr to be horribly mistaken. It's statistically proven that women applicants struggle to get into stem doctorate programs, and rightfully so, they don't belong there. examples- atomic-o-licious, brainsx , adventuresinchemistry, i can't fit anymore but you get it

It doesn’t seem dated, your attitude is dated. This is the 21st century.

Women deserve to be in STEM programs just as much as men. I’d wager they deserve to succeed in the Sciences even more than men because of the sexism and misogyny they experience.

They struggle to get in because they’re the minority, and a lot of people who could admit them are sexist (regardless of gender) because of the society they grew up in. Its not through any intellectual weakness. These women are amazing and just as smart as the men in their fields.

You have no right to say these things to these amazing women, many of whom I consider to be friends.

Wow. That seems like really fucking wrong. And offensive.
And I would love to take some more time out of my day to be pissed about it.
But…
image

It seems that I have a lot of fucking science to do. 
So, uh, screw that.
If anybody needs me, me and my lady bits will be getting some fucking science done.

I’m oddly excited to have been name checked by this shitty anon. Because it means that the very fact that I got into an Ivy League, top 15 science PhD program (where I fucking belong) is a giant fuck you to shitty anon. Also, shitty anons make Lewis sad. Because Lewis is a feminists science hippo.

imageBest way for me to deal with shitty nonnies who think women can’t do science? DO MORE SCIENCE!!!! MWAHAHAHA

Crap, I’m a woman biologist. I’d go get another career but I have a groundbreaking thesis on rapid evolution of reproductive isolation between seed beetle populations to finish. 

I’m not a well-known tumblr scientist…but I am a scientist all the same. And while I could probably obtain a more gender-appropriate occupation… I’m pretty content with the fact I’m an atmospheric chemist Additionally, I am also one of the few women who have managed to be selected to intern at NASA’s airborne research program.

Do I not deserve a place in the STEM fields, anon? 

Hey ladies! Mind if some physicists join in?

Oh, me? What do I do? I try to understand why superbursts happen in neutron stars! This is important because: they shouldn’t happen but they do. And the implications could be astoundingly helpful for things like, oh I don’t know, nuclear fusion.

Oh, just me, at a conference after presenting this:

So yeh anon, you’re wrong and very very very outdated in your opinions 

oh wow this anon thinks that women don’t belong in STEM—

better throw my archaeology B.A. in the trash, burn my thesis and stop teaching biology, chemistry and physics to the 8-12th grades.

OH WAIT

I’ve got image 

SCIENCE TO DO

NO TIME FOR SEXIST MAN CHILD ANONS

oh I guess I should burn the cheque I got for guest lecturing in grad school too—

image

Sorry, no time to answer douchey anon. To busy getting paid handsomely to do research things like this

image

While dressed fabulously like this

image

Because unlike the bullshit movies would tell you, geologists don’t wear white lab coats. Something to do with all that dirt. 

I’d tell my grad school and all the funding bodies that gave me a fellowship and research grants that they were totally mistaken because girls don’t science well except OOPS ALREADY GOT MY MS IN GEOLOGY, TOO LATE. 

Well darn. Guess I better just get back to doing science instead.

Okay, one last post for Math and Science Week/Future of STEM because it’s just too good, and I didn’t officially end the week yesterday as I meant to. Enjoy! You can read all the Week’s posts here.

The Ebola Outbreak: ‘A Dress Rehearsal For The Next Big One’

Until this year, the world had recorded 1,640 deaths from Ebola since the virus was discovered in 1976.

Then Ebola appeared in West Africa.

So far this year, 887 people have died of Ebola in West Africa, the World Health Organization said Monday.

To put that into perspective, more than a third of all people known to have died from the Ebola virus have died in the current outbreak.

And the outbreak is still spreading at a frightening rate. Last week, there were more than 200 new cases reported across four countries.

To find out more about the origins of Ebola — and what may lie ahead — we talked to author David Quammen. He wrote the book Spillover, which traces the evolution of Ebola, HIV and other diseases that move from animals to people.

Here’s an excerpt from our conversation, which has been edited for clarity.

The title of your book is Spillover. What does this term mean?

Spillover is the event when a disease, or the agent that causes it, moves from one species to another.

In particular, there’s a group of diseases, called zoonotic diseases, which pass from nonhuman animals into humans. And spillover is the moment when a new virus has the opportunity to leap from a bat, monkey or rodent into its first human victim.

We’re pretty sure that’s what happened with the Ebola outbreak in West Africa.
