Science side of tumblr how do I become a jellyfish

Jellyfish have no brains. You’re already pretty close.

Okay WOW

My mom has started using terms like ‘partner’ and ‘mate’ when dropping hints about me finding a significant other.

I am both touched and annoyed.

The familiar trigonometric functions can be geometrically derived from a circle.
But what if, instead of the circle, we used a regular polygon?
In this animation, we see what the “polygonal sine” looks like for the square and the hexagon. The polygon is such that the inscribed circle has radius 1.
We’ll keep using the angle from the x-axis as the function’s input, instead of the distance along the shape’s boundary. (These are only the same value in the case of a unit circle!) This is why the square does not trace a straight diagonal line, as you might expect, but a segment of the tangent function. In other words, the speed of the dot around the polygon is not constant anymore, but the angle the dot makes changes at a constant rate.
Since these polygons are not perfectly symmetrical like the circle, the function will depend on the orientation of the polygon.
More on this subject and derivations of the functions can be found in this other post
Now you can also listen to what these waves sound like.
This technique is general for any polar curve. Here’s a heart’s sine function, for instance

These functions make the most calming gif.

Anonymous said: 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.

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:

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:

"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…?

So yeh anon, you’re wrong and very very very outdated in your opinions 

image

Sorry, anon:  I’d love to stay and chat, but I’m afraid I’m too busy living in the future.

image

Dang anon by the time I was 22 I had already worked for a geology department at a museum, a lab at a university, and was a lab technician for a hospital.

Oh and my girlfriend interned for a cancer research facility before graduating from high school.

^ Said girlfriend. I also interned at a bioprocessing lab in high school, and I am going study biochemistry/molecular biology at a top liberal arts college.

Way to go ladies! I love how proud everyone is to be in the sciences!

Oh, just busy saving lives over here. And before that I scienced at the zoo, where I published about stereotypic behaviors in beavers. Proud chemistry club carrying member too. Women have been awesome at science for centuries. Gtfo misogynist. Your views aren’t just offensive, they’re ignorant in the highest degree. Go learn what women have done for the world.

I have many things to say. Let me just start off with disclosing that throughout high school, my peer-given nickname was “trailerpark”, mostly because that’s where the bus let me off to go to our mobile home.

My entire family for many generations are generally blue collar workers- loggers, truck…

Assessment statements are so fucking hard. 

You seriously want me to just judge this patient, this entire human being, and summarize them down to one sentence?

I noticed that I hadn’t seen some of my favorite blogs on my dash for a while, so i went and checked my ‘following’ list and they weren’t on there (and I definitely didn’t unfollow them). I had to go through and refollow, but I don’t know if it unfollowed others and I just haven’t realized it. This has never happened before I started using the app version. Is this a thing that happens with the app? How do I make it stop?

Teen scientist harnesses sun power to help Navajo community
New Mexico teen Raquel Redshirt uses everyday materials and the sun to build solar ovens, fulfilling a Navajo community need and winning an award at the Intel ISEF competition.
Growing up on New Mexico’s Navajo Nation, Raquel Redshirt was well aware of the needs of her community. Many of her impoverished neighbors lacked basics such as electricity, as well as stoves and ovens to cook food.
Though resources in the high desert are limited, Raquel realized one was inexhaustible: the sun. “That’s where I got the idea of building a solar oven,” the teen says.
She researched solar ovens and found that most incorporate mirrors or other expensive materials. Raquel wanted to create a design that anyone could easily afford and replicate, using readily available materials.
