I wonder whether the digital age has led to a decline in the use of atlases, which in turn might be expected to imbue a false sense of increasing objectivity as scientific practitioners of become less acquainted with analog methods.

It's strange and frustrating that most AI researchers don't seem interested in natural intelligence.
In the early days, when "neural networks" were seen as models of brains, many people seemed at least superficially interested in neuroscience. It's not like that now. I'm sure some folks would say "yeah, and aerospace engineers don't worry about bird flight, either!" but that feels wrong to me.
If all you care about is moving cargo, then sure, flight is solved, and who cares if our designs are "biologically realistic". Similarly, if all you care about is recognizing images, playing video games, and generating slop, then AI is solved. We'll just make the current solutions better.
But I think we've barely scratched the surface of what intelligence actually is! Current AI is so narrow and so shallow by comparison, yet I think people don't even notice that because they haven't actually thought about how intelligent living things are, and in how many different ways!
🧵As AI systems grow in sophistication, some people are supposing chatbots are moving toward being conscious entities.
This is incorrect, but we should be more precise about what consciousness and perception are.
If we are, we realize that minds do not create experience; experience is what creates minds. https://plus.flux.community/p/its-like-this-why-your-perception

A proposed White House rule would give political appointees unprecedented control over scientific funding.
One physicist, who helped discover the Higgs boson, the so-called “God particle,” explains how the move would’ve stifled that breakthrough.

I'm flat-out amazed that we can monitor the currents of molten metal in Earth's outer core, 2200 kilometers underground--but we can. Lately, part of that flow has reversed direction, for reasons unknown.
There's a whole other dynamic world inside the world we see.

It's really simple: if you cannot explain what is in your paper in sufficient detail for your argument to be plausible and understandable, then you are NOT doing #science:

Yes, you may be killed by falling human made space junk, but the odds remain small(ish) that will occur. The (almost inevitable) #KesslerSyndrome may also prevent future #space flights if all those #satellites in Low Earth Orbit start colliding, creating countless debris.
However, we *ALL* have to worry about the ‘chemical problem’ being created by SpaceX et al in the upper atmosphere. I have been banging on about this for a while and the attached article summarises the science in an easy to understand way - I have pasted the bit about the ‘chemical problem’ below because we *ALL* need to understand what the billionaires are doing to the planet while we are watching.

Debris on the ground attracts immediate attention, but atmospheric scientists are tracking a slower process with potentially larger consequences. When satellites vaporize in the mesosphere, 50 to 80 kilometers above Earth, they release clouds of vaporized metals that condense into aerosol particles. Those particles descend into the stratosphere, where Earth’s protective ozone layer resides.
Aluminum is the element of greatest concern. Upon reentry, aluminum oxidizes into aluminum oxide nanoparticles. A single 250 kilogram satellite generates roughly 30 kilograms of these particles. Unlike chlorofluorocarbons, which directly destroy ozone, aluminum oxide acts as a catalyst. One particle can facilitate chemical reactions that destroy thousands of ozone molecules over decades without being consumed.
Researchers from the University of Southern California’s Department of Astronautical Engineering documented an eightfold increase in atmospheric aluminum oxides between 2016 and 2022, directly correlating with the proliferation of satellite constellations, a finding reported in detail by CNET. In 2022 alone, reentering satellites released an estimated 41.7 metric tons of aluminum, approximately 30 percent more than the natural input from micrometeoroids.
Projections based on current deployment schedules suggest annual aluminum oxide emissions could reach 360 metric tons, a 646 percent increase over natural background levels, according to research highlighted by Popular Mechanics. Because these particles take 20 to 30 years to descend into the ozone layer, the atmospheric chemistry of today’s satellite fleet will not manifest as measurable ozone loss until the 2040s. By then, the upper atmosphere could already be saturated with catalysts.
NASA high altitude sampling flights over Alaska in 2023 detected the signature of this process. At approximately 60,000 feet, instruments found that 10 percent of stratospheric sulfuric acid particles larger than 120 nanometers contained aluminum and other metals traceable to spacecraft reentries, according to data presented at the American Astronomical Society meeting that year. The atmosphere now bears a permanent chemical marker of human activity in space.

If you're curious what causes that stuff threatening Garden Grove, Orange Co., CA to heat up while sitting in a tank, this EU data sheet details how things can go wrong and what can be done.
To summarize - it’s complicated.
It’s unstable material with a shelf-life that needs babying all along, and it's tricky to arrest a runaway reaction once it gets going.
Finding root cause of this failure will be a whole other game.

My NSF CAREER proposal got recommended by the review panel and PO, but denied by “upper management” who has serious misgivings on the proposed research. Will hear more from the PO tomorrow.
This has been devastating, as we have worked so hard on this, and have put on so much hope/stake on it.
I work as a scientist in the US because I believed academic freedom, but it seems not existing anymore.
I guess it’s time to really move on… I will seriously look for an alternative career.

I'm not going to go over my entire comprehensive medical history in a way that may reveal any sensitive information about me, or go into detail regarding any stressful or other adverse events (if any) that may or may not have happened to me in reality. I would prefer to resolve my own health issues without the interference of those who don't know me very well, and I don't want anyone to think I'm making others do all the hard work for me.
