As we've noted before, there's no fundamental right to algorithmic amplification. There's no free reach in free speech b/c social media isn't a town square. It's more akin to a shopping mall. The public is invited, but if the owner doesn't like what you're doing, security will escort you out.

We do already crowdfund research. It is called "taxes".

Oft dürfte krampfhaftes Propagieren schlechter Arbeitsbedingungen (entgrenzte Arbeitszeiten, Überstunden, mies behandelt werden usw.) auch daran liegen, dass Leute den Gedanken nicht ertragen, es könnte anderen besser gehen, während sie selbst es nicht hingekriegt haben, das für sich einzufordern.

The cuts "would kill the much-anticipated Nancy Grace Roman Space Telescope, an observatory seen as on par with [Hubble & JWST] that is already fully assembled and on budget for a launch in two years." Would also apparently close NASA's Goddard Space Flight Center. Huge, HUGE loss for science.

Curtailing people’s ability to read widely and carefully, to locate, assess, and compare different sources for themselves, and to write in their own voice about what they find and what it means, is arguably more effective than censorship. It is also one of the most obvious effects of generative AI.

Our goal is to publish this in Bioengineered to inform their readers. However, we are not willing to pay the APC of over $3000 and asked for a waiver. @tandfresearch.bsky.social has offered us a 50% discount but that's not good enough. They promised to respond within 3 days, 10 days ago....

The whole #MyanmarEarthquake rupture in one interferogram! This is three consecutive wide swath frames of ALOS-2 data, provided by JAXA through agreement with NASA. The line-of-sight (LOS) is ~perpendicular to fault strike, so most of what you see is vertical motion at bends and steps of the fault.

It's #1stApril but this is no joke. The clock is most definitely ticking. A catastrophic chain reaction of space debris causing collisions, each creating more debris, is not just a possibility, it's already under way. In some orbits, we really could run out of space. Is it a crisis?

Very nice entry > If some bit of folks wisdom cures diseases conventional pharmaceuticals won’t touch, get some trials set up and let’s figure out how and why, and use it for the benefit of all humanity. There’s no greater sign of respect than that. 👍

I thought it would be cool to take a #microCT scan of romanesco broccoli that came in my meal kit this week, and I was not disappointed! What a stunningly beautiful vegetable 🤯 The scan was taken with our Rigaku HX130 (@rigakucorporation.bsky.social) here at Beckman (@beckmanillinois.bsky.social)

My call is to @spie.org and @optica.org to consider this as well 💡

Lets replace search with "AI" then! Totally logical if you ask me. Even more worth it when you know they're exponentially overtaking the airline industry in their carbon footprint. Study: www.cjr.org/tow_center/w...

So here is the Heiligenschein raytracing, where we see that retroreflection with a smooth reflectorshows a clear caustic and separation between red and blue! This will be washed out with randomness in reflected angles using a diffuse reflector. @johncnaylor.bsky.social

Can we call this a delta-pulse and have someone already looked at market response functions? Do we see relaxation oscillations? How do we do things go GIANT PULSES? I guess this is what they're after, at the end. 💡🧪

A friend included this anti-acknowledgement section on her PhD thesis. She also added the proposition: “Systematic bullying and undermining of girls and women in STEM starts early on and is the reason why they do not stay in science and related fields.” Absurd we still need to go through this 🧪👩‍🔬
