I'm teaching calculus based physics for the first time this semester. Usually, I get the trig/algebra based intro course. I feel parts of my brain waking up that haven't been roused in many years.
I like it. Hope my students do too.

Observations of the thermal energy in a baby galaxy cluster 12.4 billion light years away are at least five times greater than theories predict, suggesting much more energetic early cluster growth than predicted by current models. 🧪⚛️ physicsworld.com/a/hot-ancien...

If you haven't heard anything from Die Spitz yet, look them up and have a listen. Reminds of the best of punk/metal/cathartic screaming that I would listen to in college. Adding them to the list of live shows I would love to get to see once I get my kidney transplant.

I have a dialysis (home, PD) treatment tonight and a lecture and lab to teach tomorrow. Do I still try driving for 90+ minutes to get somewhere far enough north of LA to see aurorae?

N95s offer superior protection against flu and Covid.
They can protect your health and the health of those around you.
Many people also find them much more comfortable than surgical masks.
If you can’t afford them, look for your local mask bloc.
If you can afford them, please donate!

For tax year 2018, I filed to increase my withholding exemptions from 4 to 22 to keep money that I knew I would be getting as a tax credit. Maybe it's time for workers in affected states to do something like that to keep part of their paychecks out of federal hands.
Here's the full list, according to a DOJ press release dated August.
In effect, every blue state except for Hawaii, Maine, Maryland, and Massachusetts (all except HI had Republican statewide electeds at some point since 2018) will have their funding withheld:

WELL NOW, would you look at that? A massive, 24-YEAR-LONG study of MORE THAN 1.2 MILLION people in Denmark found NO LINK between aluminum in childhood vaccines and autism, asthma, OR chronic disorders.

Don't try the "once they're out of sunlight, they're not visible" argument. With a big enough aperture, you're still getting data corrupted. 🤬🖕
What’s that in the sky? Satellite light trails could corrupt images captured by space telescopes like Hubble and potentially make some data unusable. #physics #astronomy
As satellite population surges, so does the impact on astronomy
Images captured by ground telescopes are getting contaminated by sunlight reflected off satellites. Space telescope data can get compromised too.

So far, we have too much oxygen in some early galaxies. We have evidence of direct collapse SMBH. We have other indicators of rapid galactic evolution. Also, discrepancies in speeds measured relative to the CMB and distant radio galaxies. Now this finding.

‘Profound impacts’: record ocean heat is intensifying climate disasters, data shows
Oceans absorb 90% of global heating, making them a stark indicator of the relentless march of the climate crisis
The world’s oceans absorbed colossal amounts of heat in 2025, setting yet another new record and fuelling more extreme weather, scientists have reported.
More than 90% of the heat trapped by humanity’s carbon pollution is taken up by the oceans. This makes ocean heat one of the starkest indicators of the relentless march of the climate crisis, which will only end when emissions fall to zero. Almost every year since the start of the millennium has set a new ocean heat record. Continue reading...

"Secret police" is often misunderstood to mean a force that operates covertly, with all their operations secret.
But a secret police force's actions are often public. The secret part is hiding their identities, because they're breaking laws to hurt politically disfavored people, and fear reprisals.

It’s almost like green energy is the only way forward and a handful of oil barons are doing everything in their power to keep that from happening so they can get even richer at the cost of literally everything else in the world.
Wall Street’s biggest banks made more money financing green projects than they did from working with fossil fuel companies for a fourth straight year, even as they faced ongoing pressure to pull back from the business

If you can't stay home, you will mask around others until there is no possibility you are contagious.
