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

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?

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 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
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—
Sorry, no time to answer douchey anon. To busy getting paid handsomely to do research things like this
While dressed fabulously like this
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.
Do yourself a favor and look up Ada Lovelace and realize you owe every single thing you’ve done on a computer in your entire life to her.

Warfarin is an anticoagulant normally used in the prevention of thrombosis and thromboembolism, the formation of blood clots in the blood vessels and their migration elsewhere in the body respectively. It was initially introduced in 1948 as a pesticide against rats and mice and is still used for this purpose. In the early 1950s, warfarin was found to be effective and relatively safe for preventing thrombosis and thromboembolism in many disorders. It was approved for use as a medication in 1954 and has remained popular ever since; warfarin is the most widely prescribed oral anticoagulant drug in North America.

“The Flow II" film by Bose Collins and colleagues features a ferrofluid, a magnetically-sensitive liquid made up of a carrier fluid like oil and many tiny, ferrous nanoparticles. Although ferrofluids are known for many strange behaviors, their most distinctive one is the spiky appearance they take on when exposed to a constant magnetic field. This peak-and-valley structure is known as the normal-field instability. It’s the result of the fluid attempting to follow the magnetic field lines upward. Gravity and surface tension oppose this magnetic force, allowing the fluid to be drawn upward only so far until all three forces balance. (Video credit: B. Collins et al.)
This is Pillomena…probably.
Land snails aren’t really my thing (meaning I don’t know much about them) but I’m quite fond of them; they’re diverse, easily found if you know where to look, and really quite lovely close up. This one is from Kallista in the Dandenong Ranges, on the outskirts of Melbourne. It belongs to the family Charopidae which is composed primarily of small species (this one is about 3-4 mm across) most commonly found in wet forest and rainforest habitats. Charopids are most diverse in New Zealand, on islands in the southwest Pacific and in Australia where there are around 75 described genera, hundreds of species, and many to be formally described.

MIT Finger Device Reads to the Blind in Real Time
“Scientists at the Massachusetts Institute of Technology are developing an audio reading device to be worn on the index finger of people whose vision is impaired, giving them affordable and immediate access to printed words.
The so-called FingerReader, a prototype produced by a 3-D printer, fits like a ring on the user’s finger, equipped with a small camera that scans text. A synthesized voice reads words aloud, quickly translating books, restaurant menus and other needed materials for daily living, especially away from home or office.”
Read more from Boston.com.
"The scientific man does not aim at an immediate result. He does not expect that his advanced ideas will be readily taken up. His work is like that of the planter — for the future. His duty is to lay the foundation for those who are to come, and point the way. He lives and labors and hopes."

Human cortical neural stem cells
Cortical neurons are located in the cerebral cortex of the brain, a region responsible for memory, thought, language, and consciousness. Neural stem cells are “immature” cells committed to become neurons and helper cells of the brain. Neurons are the liaison between our brain and the world. When we eat a lemon, neurons connected to our taste buds tell the brain that it’s sour. Messages from the brain can also be sent elsewhere, as when neurons command muscles to contract while lifting a heavy object.

Do beautiful sounds have especially appealing waveforms?
God, I love this question.
The answer is, kind of. Yes. A bit.
A pure tone, that beeeeeeeeeeeeep of, let’s say middle C is a sine wave with a frequency (pitch) of about 261 Hertz. That means 261 waves pass a point (like go into your ear) every second. The higher the frequency, the higher the pitch I like how they look, they’re so simplistic, but so mathematically powerful.
The notes of all instruments are based on sine waves. When a violin and piano both play middle C, the C sine wave is there, but so are other little quiet bits of other frequencies, these are called overtones and they’re different for each instrument. These change the waveform of the instrument and say why a C on a piano is different to a C on a guitar. That’s called the timbre of an instrument.
What are beautiful though, are harmonies.
Harmonies are when two notes have frequencies that are simple fractions, if one is twice as high as the other (2/1) it’s an octave. If the ratio is 3/2 it’s a perfect fifth. There’s a little more to it than that, but my musical knowledge doesn’t extend much further than playing Doctor Who on the ukulele.
Harmonies look really pretty, see:
See the way some of the bits that don’t move (the nodes) arrive at the same place at the same time. There’s a theory that our brains like that, that the two notes trigger neurons at the same time, so that’s why we like it.

It’s not uncommon to see small invertebrates hitching a ride on larger ones. Crabs in the intertidal zone will often have barnacles or limpets attached to their exoskeletons. In this wonderful example of commensalism, an anemone appears to have settled on the shell that this hermit crab calls home. The anemone (like all cnidarians) has stinging cells that help protect the crab from predators and benefits from having a free ride around the seafloor habitat. The anemone also receives scraps from the crab’s feeding activities. When the crab outgrows its borrowed shell, it finds a larger vacant shell … and brings the anemone along to share its new home.
