Plasma physics, mostly via kinetic simulations on supercomputers. I occasionally (but not actually every day) post a "Paper of the Day" #potd that may or may not be related to my work.

Donald Trump is not a king β€” and his administration is not above the law.

Today, the court confirmed what we all know: there is no credible evidence of a rebellion in the state of Illinois.

And no place for the National Guard in the streets of American cities like Chicago.

Yesterday brought us 5.19" of rain, putting it in the top 10 rain days. This did not come in a storm, but in a steady soaking rain. Increased rainfall and heavier rain events is a result of climate change in the Bluegrass.
Last night we had a spectacular dense bird migration (yellow on the map).

The papers will be "lost" by police in the same way homeless sweeps regularly destroy all of a homeless person's ID.

Then they will deport anyone without citizenship papers.

To properly reach the Jupiter system in July 2031, #ESAJuice relies on ephemerides - predicted positions of celestial objects at specific times.

Mid October, you have a chance to help improve those ephemerides.

Trump is now calling for the arrest of elected representatives checking his power.

Some really interesting ideas here (pre-print) from Michael Kramer and Simon Johnston (SJ works with us!).

Unlike the conventional concept of radio emissions in millisecond pulsars coming from polar caps, could they also be coming from regions where gamma-rays are emitted?!

Good news from the other place: Ham radio operators have detected Juno's carrier signal. We don't know if the mission will be continued (its funding expired Oct 1) but it at least wasn't plunged into Jupiter without our knowledge.

About 1 in 3 US Nobel prize winners are immigrants.
About 1 in 4 were government employees at some point.
About 44% of all Nobel prize winners were educated in US higher education.
As Trump demands a Nobel prize, he is destroying the means by which America came to dominate the prizes.

Valuable info about the Physics Nobel Prize today from Prof. Joseph Barranco at SFSU on Martinis and Devoret being a grad student and postdoc in Clarke's lab at UC Berkeley & Clark and Devoret being immigrants. "California *public* education made this happen. Immigration made this happen." βš›οΈ

Canceling energy projects like this, including wind farms, is an immense waste of money.

Additionally, of course, it takes the US out of the technology competition.

Lose-lose.

Flying cars are the perfect example of a point solution: trying to solve a systemic problem (traffic) with an individual product (fly over the traffic).

But traffic is not a technology problem; it's a social problem. Remote work, congestion fees, and dense transit-connected housing solve it better.

There is no budget "deal" to be made President Trump has so broken the constitutional framework as to make joint normal, responsible government impossible.

How do you find a compromise budget that reflects the priorities of 535 members of the House and Senate when Trump will just withhold any money he doesn't want to spend? A representative democracy cannot function as Trump has broken the US system this year. www.doomsdayscenario.co/p/there-is-n...
