I'm a scientist studying fluid dynamics in the cores of rotating planets and stars. I mostly post pics of clouds and timelapses. All media by me. He/him.

Tonight, two of the white nationalists I reported on in this piece showed up to attempt to intimidate me on a private night out at a small music venue.

I’ll have more to say tomorrow. I’m safe.

They also didn’t pay cover 🖕

Keeping time between the equinoxes I compute the eccentricity of the Earth's orbit based on the observation that there are more days between spring and fall than between fall and spring.

Ever noticed how there are more days between spring and fall than between the fall and spring (in the northern hemisphere)? That is due to the eccentricity of the Earth's orbit. I talk about it and do the math in this blog post ⚛️ 🧪

The painting "Night in the Steppe" shows a vast plain under a bright full moon, the light being distributed over the landscape and the water in an almost magical way.

The painting "Night in the Steppe" shows a vast plain under a bright full moon, the light being distributed over the landscape and the water in an almost magical way.

This work is made by the renowned Ukrainian artist Ivan Marchuk, who invented the unique painting style called "plyontanism" (from the Ukrainian word plyontaty, meaning "to braid"). This technique consists of hundreds of fine, intertwined lines that create depth and an almost textile-like texture.

Picture of the sun, without any filters, but through a heavy mist. It’s mostly gray except by a slightly brighter disc in the center. A few sunspots can be seen.

The #sun this morning as seen through a heavy #Belgian #mist. No filters. You can even see some #sunspots. 🔭

Discovering exoplanets with machine learning Develop a machine-learned model of stellar spectra and instrumental quirks, and use it to discover exoplanets in radial velocity data.

Do you already have a Masters? Do you want to do a PhD in exoplanet radial velocity surveys with me at Macquarie University in Sydney?

Then have I got an ad for you!

You know what I love about Sterling K. Brown?

He’s one of the few (maybe only correct me if I’m wrong) Black Actor who vocally acknowledges and gives love to his Number One fan base - Black Women.

AI is like guns - the very real and baked in harms outweigh the possible acceptable use cases so much that it should be ok to just say ‘ok we can’t have those use cases’ or find other ways

Greyscale picture of Jupiter through a backyard telescope. It's round, with alternating bright and dark bands. Also a dark spot, the Great Red Spot, a storm raging for at centuries. The bright dots near the planet are  three of its moons.

I am an astrophysicist, but looking at Jupiter through a telescope invariably takes my breath away. Never gets old. Here you can see the Great Red Spot and three of the galilean moons. 🔭 🧪

Amplifiers of Epistemic Posture Essays and writing on AI

I'm a cognitive scientist with an interest in epistemic vigilance, and this essay that's been going around gave me pause.

I don't think it's straightforward to apply the concept of epistemic vigilance to interactions with LLMs, as this essay does.

Greyscale image of the surface of the moon showing two of the "Mare's"  and a mountain range that separates them. A number of craters can be seen too.

My telescope with its camera pointing at the moon a bit before sunset. You can see the moon against the blue sky in the background.

Clear sky over Belgium today. The #moon looked great! here a pic of the mountains between Mare Imbrium and Mare Serenitatis. Very old, formed around 3.9 billion years ago. And reaching up to 5km high!

Yes! De eerste grootschalige vogeltrek verscheen afgelopen nacht (24/25 feb) op de weerradar! Opvallend: intensieve trek over de Noordzee vanuit Engeland. Vogels die daar overwinteren, kiezen duidelijk hun moment voor de oversteek: droog weer en een gunstige windrichting. Bye bye winter!

Research scientists have no shot at having a permanent position, ever. But at my university, we're now required to send annual reports of our activity in order to be evaluated. For what exactly? Just to be able to keep our jobs? 🧪⚛️

Sometimes only a part of a ship is launched. Flotation tests are performed on individual pieces and then the vessel gets assembled. This on the @Fincantieri shipyard in Castellammare di Stabia. The Regio Cantiere di Castellammare di Stabia was founded in 1783.

Does academia select for sociopaths, or does it reward sociopathic behavior?

F.D.A. Refuses to Review Moderna Flu Vaccine

Being in New Zealand has been glorious, and I’ve been trying to bring joy to our world that needs more joy and less rage posting.

But this is a rage post. You need to read this gift article because you need to be enraged.

I’m fine with *exploring* the solar system, with robotic probes and some crewed vehicles.

But that’s not the same as trying to live there…

Thread is absolutely correct. The "fooled you" dollars are not good and will only get worse as the MLM scam spreads. It won't displace established authors, but is a denial of service attack on new authors finding an audience, their new gem in a sea of slop as readers stick to known authors.

AI "impedes [theory because we're] interested in human-understandable theory and theory-based models, not statistical models which provide only a representation of the data. Scientific theories and models are only useful if [we understand them and] they connect transparently to research questions."
