it's science but not rocket science

23 Black Female Scientists Who Changed The Damn World

Okay so prior to Alice, people had known for hundreds of years that a potential treatment to leprosy existed in the form of something called Chaulmoogra oil. It was too thick to effectively circulate through the body, but Alice Ball, science prodigy and chemist extraordinaire, was the one who FINALLY figured how to turn it into a working treatment. It’s thanks to her that a leprosy crisis was avoided in the early 1900s. Bless you, Alice.

Stay with me for a second because this is actual rocket science. Centaur is a second-stage rocket launcher: the workhorse of the rocket world used to propel countless probes and satellites into space. It’s been invaluable to NASA since its creation, first allowing the U.S. to catch up to the Soviet Union during the space race, and eventually propelling spacecrafts to land on the moon and fly by other planets in the solar system.

So yes: Annie Easley helped DO that. She also contributed energy research to power plants and electronic batteries, which enabled the creation of hybrid vehicles. Go ahead and thank Annie for those, too.

Prior to Jeanne, the impact of discrimination and its accompanying stress factors were rarely explored or acknowledged in relationship to health. She also researched the impact of racism on childhood development and ways to approach therapy that addressed the needs of people of color. And Jeanne broke a ton of ground for black psychologists through her roles in academia and her publications.

Jewel researched ways to alter cell growth AND experimented with growing human tumor tissue outside of the human body to use for cancer treatment tests (instead of testing on living people). As if that wasn’t enough, she also helped to form the National Science Foundation’s Committee on Women and Minorities in Science.

The chair of the U.S. Nuclear Regulatory Commission monitors the byproduct of nuclear reactors, so it’s a pretty big deal. Shirley also served on a bunch of advisory boards for international security and energy, AND she was the first black woman to get a Ph.D from MIT.

23 Black Female Scientists Who Changed The Damn World

every time i hear someone talk about lwymmd like “i don’t like how she’s blaming her actions on other people like oh someone made her do something” i just want to yell at them that they’re missing the entire point and “look what you made me do” isn’t talking about how she did things and it’s the media’s fault but rather the point is that every character in lwymmd represents stuff she’s been blamed for…. like yeah look what you made her do as in look what you pretended she did, she’s just embodying the craziness everyone pretended she was and the fact that people think it’s ridiculous is literally the point

something that always struck me as odd about the prequels is how palpatine was able to forge a relationship with anakin in the first place.

this is definitely my biggest problem with the jedi, in relation to anakin: they let palpatine, a middle aged man, get anakin, a child, alone. the fact that palpatine’s even insistent on it at all should be ringing alarm bells. there should be Stranger Danger warnings going off, people! you’re dropping the ball, men!

and i understand that, according to the comics, palpatine threw his political weight around, saying that the senate has total control over the jedi. that you can’t deny the chancellor. but that’s incorrect - the republic is corrupt, but it’s not a dictatorship yet. as anakin’s legal guardians, the council has the full right to refuse palpatine access to anakin - it doesn’t matter who’s knocking at your door, you’re supposed to protect your charge. 

but the jedi handed him over. the second palpatine pressed, they folded; and no one tried to curb anakin’s interaction with palpatine, even though it should be clear that an old man wanting to talk with a minor day after day after day is suspicious. especially since the jedi were suspicious of palpatine anyway

Yes, sure its fun to see a lady spin around like that, but I had one of my friends ask me - “Where do you even use this mate?”

Here’s one application that I know very well off.


Spin Stabilization

If you have ever seen a rocket launch, you might know that sometimes the rockets are given a spin while launching. This is known as spin stabilization.

Basically, the rotational inertia of the rotating body will stabilize the rocket against any disturbances and help maintain its intended heading.

The same principle is used in rifling of firearms as well. **


YoYo DeSpin

Okay, now there is the question how to “De-spin” the rocket:

Well, you do what the lady does: stretch out your arms and you will slow down !

The rocket has weights connected to a cable that stretch out and almost immediately the rocket slows down. This maneuver is known as the YoYo DeSpin. ( Damn good name ! )

All thanks to the conservation of angular momentum !

Have a good one !


* Another method to stabilization : 3-axis stabilization

do you ever think about the fact that you sat in front of your computer screen and watched one direction do skits, try and spectacularly fail at world record attempts, make pottery, and have a wrestling match and a runway show, and other random shit overrun with technical difficulties and a dash of jerry springer for 8 hours straight 

and then do you ever start crying when you think about how you’d literally give one of your own organs to have a 2k17 repeat

anonymous asked:

I feel kind of embarrassed asking this, but I am an MJ fan and I never fully understood his vitiligo. I know he didn't bleach his skin, so how did he become lighter each era? Did he just let the vitiligo take over??

“Did he just let the vitiligo take over?”

You ask that as if vitiligo was something he could control. It was not. He had no choice but to let it take over.

How did he become lighter each era?

The vitiligo started to intensify during Thriller era (though it could be seen  during the Off The Wall era too). 


Behind the scenes of Captain EO (1985-86), he’s rehearsing without makeup and you can see huge blotches on his face (can’t find video of it rn but here’s a pic where it’s on his hands)


Then we get to Bad era (1987), and his skin got a lighter still. His vitiligo was a gradual thing, that made him lighter over time. The reason people during that time thought he “all of a sudden” got lighter is because 1) Michael never publicly said anything about his disease and 2) quite simply put, the man wore makeup to cover what would have made those people realize he had something wrong with his skin: the blotches. Also 3) though Vitiligo was attacking his face during OTW/Thriller era, it did not fully cover his entire face. But you could tell it was starting to cover his entire face in late 1984, basically when Say Say Say was being filmed (and even before Say Say Say was filmed). In fact you could tell because his makeup looked a little funny

(a.k.a. He was trying to cover the vitiligo using darker makeup—which didn’t work in the end and brings us to why he was so light-skinned in BAD (1987). It was because in BAD and Captain EO, he finally realized he could no longer use darker makeup and had to use makeup that matched his Vitiligo progression at the time).

If you’re covering up the blotches with makeup every time you’re out in public, without explaining what’s happening to you, you get what MJ got: people assuming that he either just became light-skinned out of the blue, or assuming that he bleached his skin. So between 1982 to 1987, which is 6 years of Vitiligo progression, MJ went from this

to this


Then at the VERY start of the Dangerous era (when he was still recording for the album), it progressed further. In The Dilip Mehta photoshoot (early 1991), Michael still looked like he did during Bad era.

But between the period of that photoshoot and when the video for Black or White came out (late 1991), the vitiligo progressed a LOT.

The Dilip Mehta photoshoot was done in January of 1991. The video for Black or White was shown in November of 1991 (and filmed a few months before that). That’s 9 to 10 months of Michael’s skin getting lighter because of Vitiligo. 9 to 10 months of Vitiligo further attacking his face and hands with blotches.


The rest of Michael’s Dangerous era videos were released in 1992, like Remember The Time (filmed in January of 1992; shown to the public in February of 1992). Again, that’s 3 to 4 months of the Vitiligo progressing more. 

(obviously he’s wearing makeup here, but without makeup this is what was really going on in 1992):


Essentially, I’m trying to get you to understand that Vitiligo is a progressive disease, that usually shows up in a person’s childhood as very small, unnoticeable blotches, then gradually progresses into bigger blotches and a much more noticeable and lighter complexion. And Michael was so embarrassed by this disease he had that not only did he wear makeup to cover it, but he also forever wore long sleeved shirts and long pants to hide all the blotches that were slowly but surely taking over his body.

With all that being said, what we got was his skin appearing porcelain in appearance toward the end of his life. 

So yes, he got lighter year after year after year because of the disease he had. Here’s a final look at what I’m trying to get at.

MJ in 1977:

MJ in 1987:

MJ in 1997:

MJ in 2007:

That’s 10 years in between photos and 40 years overall that Vitiligo was gradually taking over MJ’s body, turning his skin tone from brown to porcelain white (don’t get that confused with the skin tone of actual white people). 40+ Years of blocthes, various discolorations and him covering it up with makeup

MCU characters as quotes from me while at school
  • Tony: Pluto is a fucking planet. It orbits a star and has an axis, and gravity, it's a fucking planet. It's not rocket science. it only becomes rocket science when you want to visit it.
  • Rhodey: [someone notices the 'gay af' on his shirt] Yes thank you. Finally someone noticed my hard work
  • Natasha: I hate Satan because he's the one that made Eve eat the fucking apple and give her periods so I hope he's rotting in hell for making my week a hell on earth
  • Clint: [sees everyone eating their lunch and remembers its lunch time] OH YEAH FOOD [runs to the lunch line to get food]
  • Bucky: cutting off your dick would be easier than cutting off your arm
  • Sam: i wish i could just say 'fuck this shit' and fly out the window
  • Steve: Hurt my friend, I hurt you, with a SPOON
  • Scott: i don't know shit about biology I failed it
  • Sharon: I'm a badass but even I won't fight a spider. That's idiotic and I'm just gonna hide around the corner.
  • Thor: AAAAAHHHH [runs and jumps on friend] I LOVE YOU
  • Bruce: That's not probable at all why are you doing that, no, no. don't do that. for right now i'm the mom friend and i'm saying No.
  • Wanda: if one more teacher tells me to do homeWORK I"M GONNA probably do it because it's senior year and i want out of here so fucking bad
  • Pietro: [everytime someone runs by] RUN FOREST RUN [pauses as freshmen stare in confusion] fuck i'm old kill me

Why do people have such issue with raising their dog?

I have to walk this one, a super hyperactive keeshondje. He’s not allowed too many treats because otherwise he doesn’t eat his food - but guess what, because he is so hyperactive, moving forward is super reinforcing to him. So you can solve his pulling issue simply by halting, catching his attention, and then allowing him forward again.

After a 10-minute refresher course of what ‘sit’ and not-pulling are, he gave me a nice loose-leash walk the rest of the time, with an occasional reminder.

I’m OK with people not liking ItaSaku because it’s not their cup of tea, but the hostility needs to stop. Wishing death on those who ship it and wanting to dissolve in acid over it is NOT the sane thing to do. It’s a FICTIONAL pairing.
