Pinned toot

Hey everyone! I juggle roles being a Postdoc at MISU (Stockholm University), research software developer, blogger and a person. Scientifically, I am trained in , fresh out of PhD a few months ago. I study geophysical flows and turbulence.

I also maintain a:

What is a living being? Are we:

- blobs of organic chemicals capable of rational thought?
- heat engines capable of taming the otherwise natural order of growing entropy?
- self correcting and replicating machines?
- one unit in the sprawling ecosystem of planet Earth, a superbeing?

PhD vacancies 

3 positions open at MISU, in science and . Topics include: arctic climate processes, coastal upwelling dynamics, extreme storms.

For better or for worse, I've put my entire Machine Component Design course online. All 9.5 hours spread over 55 videos.

Do you know when global population *growth rate* peaked? "The answer may surprise you" (Forward to all your Matlhusian edge-buddies)

I added addon to my browser, and it has been pretty effective so far: because I have not been posting here so often.

In an upcoming @ieeesoftware #paper I've conducted a longitudinal #genderstudy of authors of #publiccode commits from @swheritage, analyzing 1.6 billion commits contributed by 33 million distinct authors over a period of 50 years. Short thread w/ links at the end 👇 #FOSS [1/6]

❝Since her death in 1979, the woman who discovered what the universe is made of has not so much as received a memorial plaque. Her newspaper obituaries do not mention her greatest discovery. […] Every high school student knows that Isaac Newton discovered gravity, that Charles Darwin discovered evolution, and that Albert Einstein discovered the relativity of time. But when it comes to the composition of our universe, the textbooks simply say that the most abundant atom in the universe is hydrogen. And no one ever wonders how we know.❞ — Jeremy Knowles, discussing the complete lack of recognition Cecilia Payne gets, even today, for her revolutionary discovery. (via alliterate)


• Cecilia Payne won a scholarship to Cambridge.

• Cecilia Payne completed her studies, but Cambridge wouldn’t give her a degree because she was a woman, so she said to heck with that and moved to the United States to work at Harvard.

• Cecilia Payne was the first person ever to earn a Ph.D. in astronomy from Radcliffe College, with what Otto Strauve called “the most brilliant Ph.D. thesis ever written in astronomy.”

• Not only did Cecilia Payne discover what the universe is made of, she also discovered what the sun is made of (Henry Norris Russell, a fellow astronomer, is usually given credit for discovering that the sun’s composition is different from the Earth’s, but he came to his conclusions four years later than Payne — after telling her not to publish).

• Cecilia Payne is the reason we know basically anything about variable stars (stars whose brightness as seen from earth fluctuates). Literally every other study on variable stars is based on her work.

• Cecilia Payne was the first woman to be promoted to full professor from within Harvard and the first woman to head a science department at Harvard. She also inspired entire generations of women to take up science.

• Cecilia Payne is awesome and everyone should know her.

Earth science adjacent 

A meta-research question. In , I often see as a noun in titles of articles and talks. Engineering, in contrast, rarely uses this word and instead Statistical description or Uncertainty or Dynamics are used instead. Variance and probability density functions may appear in the results and discussion but rarely in the title

Why do you think that is so? Is Variability often a central research question in meteorology that it is emphasized in the title?

i camt really art but if anyone wants to take this and run with it go ahead

Communicating science and its impacts is a key priority of the meteorological community #scicomm

Influences on rainfall patterns across the US from ENSO and the MJO can sometimes enhance or cancel each other out. Learn more in our latest ENSO Blog by @mbarcodia, PhD candidate at @UMiamiRSMAS and writer at the climate blog @seasonedchaos.


Earth vs Mars 

Great moment for NASA and space exploration of our neighboring planet Mars. I hope they keep such missions realistic for the foreseeable future and don't distract us too much by giving high hopes of colonizing Mars.

There is no Planet B.

about "Megadiverse countries".

I am not sure how comparable these countries are in ethnic- and bio-diversity.
