"it’s astonishing how many contemporary takes on classic works of fantasy and science fiction fly in the face of both common sense and authors’ known views of the world."

"Intriguingly, while people with little education are often zero-sum thinkers, people with PhDs may be more zero-sum than anyone, which speaks volumes about the scramble for scarce scholarships and research positions in elite education."

As a guy who simulates Earth’s core flow for a living, all the simplifications made by people are wrong and simplistic. Except I made them. Then they are fine and completely justified.

9 runs in the 11th inning! Wearing my giants hat with pride today. www.mlb.com/news/justin-...

the end of an era

🤮 NASA has fired people, closed their diversity offices, threatened to kill nearly-completed projects, threatened to massively reduce funding, and made everyone working with NASA over the last 100 days an anxious, emotional wreck. NASA should be ashamed of themselves for writing this. 🤮 🔭 🧪

Well worth a read

Zenith moment between the tropics!

I wrote a research note about the recent publication of the MIRI/LRS spectrum of K2-18b. The authors had claimed the detection of potential signs of life. I find the data to be consistent with a flat line 🔭🧪

This thread is an *excellent* break down of the latest results. TL;DR- don’t get your hopes up

Check out our latest published study! We find that imposing continuity of the electric field at a sliding interface can be tricky, and advice caution in numerical simulations 🧪🌎🧲

Je participe au printemps des sciences demain!

🪐 Ce samedi 29 mars à 20 h, Jérémy @[email protected] de l' @ORB_KSB donnera à Louvain-la-Neuve (Place des Sciences) une conférence sur les océans cachés sur les lunes de glaces de #Jupiter et de #Saturne. 👁️ Plus d'infos sur ce lien: www.printempsdessciencesucl.be/evenement/8/...

Happy equinox everybody! Today at 9:01 a.m. GMT, the Sun will be at the vernal point: one of the two points of intersection of the Earth’s orbital plane (aka the ecliptic) and the equator. Daytime and Nighttime are evenly split 12h/12h everywhere on Earth today (hence the name ‘equi’-‘nox’).

Clouds parted just in time for maximum totality at 1:58 a.m. here. The total lunar eclipse as viewed from my front door:

During the ESA Hera #Mars flyby on March 12, scientists of the @orb-ksb.bsky.social took pictures 📸 of Mars and its moons Phobos and Deimos with the TIRI camera onboard Hera. 🤩 Look at this photo of Deimos from the far side, with Mars in the background ℹ️ www.astro.oma.be/en/hera-clos... 🔭🧪📷

About fifty years ago, NASA strapped a message in a bottle to a rocket and flung it into the deep dark It wasn’t supposed to go this far, but it did. Long past its mission, it’s still out there so far away now that a simple hello takes a day to reach it, and another day to hear if it says hello back

Call to action: Stand Up For Science rallies organized world wide for March 7. #3E #USProtests #March7Science If you aren't near the site of a #StandUpForScience rally, join the nationwide campus and workplace walkout at 12:00 PM. More information here: standupforscience2025.org/local-event-...

WTF??

Science (and science policy, and conservation) friends, I need your help! We are collecting *specific, clear* examples of harms caused by the Trump administration's attacks on science, to be included in an open letter. Can be links to news stories/social media posts. 🧪🦑🌎 #SciComm #SciPol

The breadth and scope of cowardice amongst our scientific leadership is staggering.

#economics in a nutshell: the poor don’t wanna work because they earn too much money. The rich people don’t invest because they earn too little.

“So why would I go through the pretense of peer review if the process is ultimately outsourced to an algorithm? I do not care for the aesthetics of peer review. We are not children playing academics. We are supposed to be doing substantive, not performative work.”

The main DEI page from @agu.org has been modified to take diversity out of the title. Glad to see it's not deleted entirely, but hey AGU, we're watching what you do and remembering the big game you once talked about supporting your diverse membership. Today vs. January

Baseball is back ⚾️

There’s no mystery there. You rise up to the high spheres of education mostly by complying with imperatives and discipline from a young age. When absurd rules are set up (bibliometrics, cut throat grants selection, …), you survive if you can navigate them but you don’t change them.

'In Germany in the 1930s, scientific institutions and societies failed at every level to offer any significant resistance to Nazism,' writes @philipcball.bsky.social. 'Donald Trump’s United States is not Hitler’s Germany. But the point is surely to learn from it anyway.'

I saw @daveherreromusic.bsky.social at Rosa’s, by chance, one night of December 2022 in Chicago. I can’t thank my friend Steve enough for taking me out that night. This song from last year also slaps ass. open.spotify.com/track/1pOd74...
