Any fellow Jewslims here? As in, a parent who's a Jew, and one who's Muslim (regardless of your actual faith/lack thereof)? I've been told I'm weird and it doesn't feel good. RT if you think I'm not weird, and (pls) like/comment if you're a Jewslim too. I know I'm not alone πŸ•ŒπŸ• Disclaimer: I'm not religious like AT ALL. I love bacon and there's nothing I can do to change that. (Although kosher/halal meat actually does taste better, but πŸ– is forbidden for Jews and Muslims but, like, BACON HELLO πŸ€·πŸ»β€β™€οΈ)

Academics! Do you know of any organizations that offer travel grants to grad students to go to a conference to present their work? Please let me know if you do, I *really* want to go to this conference! (It's IPA 2018, Interplay between Particle and Astroparticle Physics, btw) It's like the perfect conference for me to gear up for PHENO, my ultimate.

"Jo, let's go."
"Nah I think I'm gonna wait till I quantum tunnel through the car door."
"Jo, the probability of that happening is e^-10^35, you'd have to wait longer than the age of the Universe for it to happen!"
Progress: only a few Universe ages left, but Jo will never know. The things you run into in the parking lot of a Ralphs in Los Angeles. Sigh.

One reviewer decimated me for not having publications when I applied for @NSF GRFP. Yesterday, 2.5 hours w/my team and we've divided up writing of my first paper. Plus *another* paper in the works. I'll have two as a 2nd year grad student. Take that! πŸ‘Š
#ShareYourRejections To be clear: I had *just begun* grad school when I applied for the fellowship. So, yeah, they pummeled me for not having a paper as a first year grad student, although I clearly outlined the research that's coming together into a publication (coming soon to a journal near you πŸ˜€)

620 ly away, a planet 3x the mass & 2x the diameter of Jupiter orbits so close to its star that temps reach 4600 K. That's ~1000 K higher than most stars! This heat allowed astronomers to, for the 1st time, find atomic iron & titanium in its atmosphere.

This should *never* have to happen to a PhD student. Quals are the most stressful part of grad, and mean shit. If you want to make sure your students have their core courses down, no test do this. Make core courses adequate, and students will have them down w/o needless stress. The only reason a PhD student should be prevented from obtaining their PhD is for failing to defend appropriately or not having the minimum GPA required. But quals on top of that? Bullshit. Once I'm done my courses I'm coming down and advocating for their removal *hard*.

This is the kind of stuff Gaia is doing---giving us unprecedented precise measurements so that sometimes, we find out a binary isn't quite what it seems, but rather, just close enough to *look* like one, but are actually really far apart. Actual binary stars are gravitationally bound, dancing about each other in their mutual gravitational pull. Visual binaries, however, might not actually be binaries, but instead appear to be because of how close they appear to each other in the night sky.

Let's clarify some things. I'm all about outreach (specifically physics), intersectional feminism, equality, inclusivity, justice, rights of women/POC/URM/LGBTQIA+.
I will not condone sexism, racism, anti-Semitism, anti-LGBTQIA+, Islamophobia, or any form of hate.
Thank you ✌ You will hear a lot about physics from me, because it's something I love more than anything. But, as a woman, and a woman in STEM, the above mentioned things matter to me, and they matter *a lot*. So you'll hear about those, too.

This white male raped a 14-year-old girl. This rapist, *because* he's *white*, will serve no jail time. NO. JAIL. TIME.
Logan Michael Osborne is a rapist and has gotten away with it because HE'S WHITE. He raped a 14 year old girl and will do NO TIME. Fuck this. Okay. For those who have doubts about the fact that this rapist didn't get time because he's WHITE, you're either fooling yourselves, or simply want to keep this shattered system intact where white men get away with everything and the only ones who do time aren't white.

I just spoke with my aunt about this abortion issue in Argentina, and, perhaps from ignorance, was absolutely *shocked* to discover that Poland is the country with the *strictest laws* in *all of Europe* with regards to abortion. I'm shook. Here, possibilities are if you've been raped, or if your life is in danger of you keep your pregnancy, and even *then*, you may not be granted an abortion.

Six Saturnian wonders in one frame: Janus, a moon that gravitationally dances w/ another; Pandora, near a weaved F ring; Enceladus, a waterworld gushing spurts into space; Rhea, Saturn's second largest moon; Mimas, the "Death Star"; and Saturn's rings. Wow.
Credit: NASA/JPL/SSI What kind of dance does Janus do, and with whom, you ask? With Epimetheus! Here's a thread I wrote on it:

Most of you know I study particle dark matter. I find this stuff so interesting that I wanted to write a thread, all about this weird stuff, to tell you why it's so cool, and what other ideas exist to explain this unknown sector of our Universe! Dark matter is something we do not yet understand (dark energy is even *less* understood, and I don't see a resolution to dark energy in my lifetime, but I'd happily be proven incorrect if someone figures this stuff out! My money is on dark matter being figured out, first).

I've been told math and sciences weren't for me (because I'm a woman). Well, here I am, a woman, and I'm working on my PhD in physics. πŸ‘Š On behalf of all women in/ getting into STEM fields (and the are a *lot* of us):
We're here, and we're damn good at what we do. And we're not going anywhere, ever. πŸ‘Š

Hi @AirCanada, when you break someone's luggage, make sure you have a replacement. My luggage broke on your airline, and you have nothing for me but to send me to the other side of the GTA to get it replaced. I have a soft, *not* hard cover large luggage. I shouldn't have to either accept a smaller luggage or a hard cover, or go to the other end of the city for a replacement. I don't have a car here, and it's an area not accessible by TTC. @AirCanada.

Hey all, I spelt "Epimetheus" wrong in this tweet of some amazing image processing, so to make up for it, I'm gonna tweet a thread of little factoids about the moon. 1) it looks like a potato that's been swiss cheesed.

This right here is a *masterpiece* of processing by none other than Jason Major: Rhea and Epithemeus in front of Saturn 😍

Rhea (l) and Epimetheus (r) in front of Saturn and its rings made from #Cassini images captu… instagram.com/p/Bkqd4ghADNh/ Although you're probably already like "duh it's gorgeous, yeah it's a masterpiece!", it's more than that: those are moons, and moons are in constant motion. Color images are produced by combining images taken in the red, green, and blue filters.

It is with great displeasure that I present to you all a day in the life of a woman in science. Because, y'know, we're just too distracting to be taken seriously, EVER. πŸ™ƒ #sexism That's a comment in response to the photos of me taken in the feature by @TorontoVerve (if you didn't see the feature, my current avi is one of them, and I've added one to this tweet). This was posted on reddit, you can take a look, here: google.com/amp/s/amp.redd…

I got interviewed by @EmilyNRome, and here's a clip of a video where I talk about the Hartle-Hawking state which I helped bring to life as science advisor for @12MonkeysSYFY! Check the link for full video + article with quotes from me and @terrymatalas: inverse.com/amp/article/46… I should also note that I was totally not prepared for the video part of the interview, and I'm pleasantly surprised with how well it turned out πŸ™‚

#Sterlini: "#Axini, wanna try this together thing again? We could both be dark matter!"
Axini: "I dunno, you were mean last time. I'm a good dark matter candidate too!"
S: "I know. Let's try!"
A: "You CAN'T bully me around anymore, got that?!"
S: "okay I'll be good! MAAAYBE." Not quite there yet, but they've gone from squabbles to just sniffing each other intently! The quest to reunite the #darkmattersisters continues. #Progress

Let's talk the so-called need to "get women interested in science". The thing is: we *are* interested (HELLO πŸ™‹β€β™€οΈ). We're everywhere. That isn't the problem. The problem is *keeping us here*. Creating a safe environment for women, esp. women of color, is the problem. Now that we're (very slowly) moving away from the "women can't do science" narrative, it's become "we need to get women interested in science". There's *always* an excuse other than the truth, which is that the climate makes it difficult to keep women here.

Thought you all might like to know, say, the probability of a human passing through a wall. Yes? Yes, because #QuantumMechanics is fun! Let's begin! The set up: a barrier with a higher energy than an electron. Think a tall wall, and a ball that didn't get thrown high enough to go over. Classically, the electron scatters back, like the ball bounces back. But in quantum, that electron has a probability of passing through!
