Scales

This is because Fahrenheit is based on a brine scale and the human body. The scale is basically how cold does it have to be to freeze saltwater (zero Fahrenheit) to what temperature is the human body (100-ish Fahrenheit, although now we know that’s not exactly accurate). Fahrenheit was designed around humans.Celsius and Kelvin are designed around the natural world.Celsius is a scale based on water. Zero is when water freezes, 100 is when water boils.Kelvin uses the same scale as Celsius (one degree, as a unit, is the same between the two), but defines zero as absolute zero, which is basically the temperature at which atoms literally stop doing that spinning thing. Nothing can exist below zero Kelvin. It’s the bottom of the scale.So.Fahrenheit: what temperatures affect humansCelsius: what temperatures affect waterKelvin: what temperatures affect atoms

Why didn’t my science teachers ever see fit to toss off this little fact?

Science.

I can’t tell what my favorite part is, but it’s either
scientists wasting budget and time to see if ants count their steps
the idea to put ants on stilts
there had to be a guy who made ant stilts and put them on the ants
confused ants

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.

image

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.

image

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?

At the CERN visiting the CMS part of the LHC where were were working for 8 months on both computational and experimental work:

Presenting our research at a conference on Physics of Living Systems:

And visiting the Wind Tunnel experiment after presenting our research at Max Planck Institute at a Advances in Cardiac Dynamics Workshop

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.

image

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

image

"don’t belong there"?! excuse you! 
Im not a science tumblr but i am a girl and a geologist so i kinda prove you wrong…?

On board the HMS Discovery, a state of the art scientific ship which anchors at the NOC (national oceanography centre Southampton)

Doing some geological mapping and fieldwork in Ingleton Yorkshire

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
image

I’ve got image 

SCIENCE TO DO

image

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 spread of the black death.

Poland

Poland, tell us your secret.

Poland is the old new Madagascar. 

If I remember correctly, Poland’s secret is that the jews where being blamed all over europe (as usual) as scapegoats for the black plague. Poland was the only place that accepted Jewish refugees, so pretty much all of them moved there. 
Now, one of the major causes of getting the plague was poor hygiene. This proved very effective for the plague because everyone threw their poop into the streets because there were no sewers, and literally no one bathed because it was against their religion. Unless they were jewish, who actually bathed relatively often. When all the jews moved to Poland, they brought bathing with them, and so the plague had little effect there.
Milan survived by quarantining its city and burning down the house of anyone showing early symptoms, with the entire family inside it. 

I reblogged this tons of times, but the Milan info is new.
Damn Italy, you scary.

Poland: “Hey, feeling a bit down? Have a quick wash! There, you see? All better”
Milan: “Aw, feeling a bit sick are we? BURN MOTHERFUCKER, BURN!!!!!”

Also, this might have something to do with it: from what I understand, O blood type is uncommonly… common in Poland. Something to do with large families in small villages and a LOT of intermarriage. The black plague was caused by a bacterium that produced, in its waste in the human body, wastes that very closely mimic the “B” marker sugars on red blood cells that keep the body from attacking its own immune system. Anyone who has a B blood type had an immune system that was naturally desensitized to the presence of the bacterium, and therefore was more prone to developing the disease. Anyone who had an O type was doubly lucky because the O blood type means the total absence of ANY markers, A or B, meaning that their bodys’ immune system would react quickly and violently against the invaders, while someone with an A may show symptoms and recover more slowly, while someone with B would have just died. Because O is a recessive blood type, it shows in higher numbers when more people who carry the recessive genes marry other people who also carry the recessive gene. Poland, which has a nearly 700 year history of being conquered by or partnering with every other nation in the surrounding area, was primarily an agricultural country, focused around smaller, farming communities where people were legally tied to, and required to work, “their” land, and so historically never “spread” their genes across a large area. The economy was, and had been, unstable for a very long period of time leading up to the plague, the government had been ineffective and had very little reach in comparison to the armies of the other countries around for a very very long time, and so its people largely remained in small communities where multiple generations of cross-familial inbreeding could have allowed for this more recessive gene to show up more frequently. Thus, there could be a higher percentage of O blood types in any region of the country, guaranteeing less spread of the illness and moving slower when it did manage to travel. Combine this with the fact that there were very few large, urban centers where the disease would thrive, and with the above facts, and you’ve got a lovely recipe for avoiding the plague.
Interestingly enough, as a result from the plague, the entirety of Europe now has a higher percentage of people with O blood type than any other region of the world. 

WHY IS THIS ALL SO COOL

When Tumblr teaches you more about the plague than 12 years of school ever did.

Just to throw a nod in, as a medieval historian, this is all credible, and is the leading theory as to the plagues effectiveness at this point. So. Enjoy your new knowledge!

Explosive pods launch seeds up to 20ft

Speaking of the evolutionary strategies of seeds, let’s all take a moment and appreciate this fantastic “exploding pod” maneuver, employed by a number of plants. Some varieties of Caigua (which I discussed last week), have to be harvested with goggles, just in case they pop!

Fantastic news for people who suffer regularly from migraine headaches. The FDA has just approved a wearable electrical stimulation device for sales in the United States — a headband that prevents the onset of migraines when worn for just 20 minutes each day.
A device like this is definitely long overdue. Some 10% of people worldwide suffer from migraines, a condition characterized by intense pulsing or throbbing pain in one area of the head, accompanied by nausea or vomiting and sensitivity to light and sound.
Developed by STX-Med in Beligum, Cefaly is a compact, portable, battery-powered, prescription device. It’s placed at the center of the forehead, just above the eyes, using a self-adhesive electrode. The headband then delivers transcutaneous electrical nerve stimulation (TENS) to the trigeminal nerve known to be involved in migraine headaches. The only known noticeable effect is a tingling or massaging sensation where the electrode is applied. It can only be used by people age 18 or older and should be used no more than once per day for 20 minutes. [x]

… huh.
