My notes have been scattered. It’s ok, most of them remind me of the same thing.

This week’s main story is about how more and more white nationalists, antisemites, and Nazi sympathizers seem to be integrating into the Republican Party, how some of them are currently running for office, and how old you can be for JD Vance to consider you “a very young boy.”

it's really, really fucking infuriating to be ruled by public officials so unbelievably, unfathomably, stupidly fucking racist such that you can't really finish your thoughts on the matter out loud because they are in fact public officials

you write 500,000,000 in ARABIC NUMERALS you slack-jawed brain-dead carbon sink of an undead racist, go try and prove germ theory wrong firsthand by huffing e. coli cultures

One of the biggest mysteries of the Wow! Signal is its exact location, with two possible positions in the sky. Our #AreciboWow team has solved this mystery using three independent methods. We’ll present our findings in 2027. We know! 😉

I was lucky enough to illustrate for @jmcelroy.bsky.social's new book and here they are if you'd like to see them!

Science is inherently political and when our government is actively hostile to science as a whole, publications should be able to write about it without being censored. Alas. www.thenation.com/article/soci...

Look at all the galaxies! This is an intermediate step in a process of an astro image I am doing. I removed the stars and inverted the image. Every one of those dots are a galaxy. 🔭

Never forget that when Seoul, Korea removed the Cheonggyecheon expressway in 2003 and replaced it with a restored stream, 1000 acre park and improved public transit, not only did it TRANSFORM the city’s public life and economic success, but the car traffic got better. The car traffic got BETTER.

Test images of the full Moon last night to determine exposure bracketing for the 8/2/26 total eclipse. I made a regular and mineral Moon with the 1/8000s exposure, ISO 100. My next step will be working out the max unguided exposure by imaging stars at the same 18 deg declination. #astrophotography

The claim nuclear is more reliable than renewables is a myth. WindWaterSolar has not only met a higher percent (12.8%) of demand during its worst 5 min in all of 2026 than nuclear during its best 5 min (12.0%), but has also met seasonal & daily demand better than nuc from 2023-26 on the CAISO grid

What if, centuries from now, we could look back at a time when we decided to clean up our atmosphere? In "The Day We Cleaned the Sky", CO2RE Artist Selina Wagner tells a story from the future that celebrates our choice 500 years earlier to use greenhouse gas removal to do just that. #SciArt

Incredible that the @bostonglobe.com looked at decades of dangerous driving conditions and deaths on the Jamaicaway/Arborway/Riverway and came to the conclusion that Frederick Law Olmsted's CURVES are the problem! Straightening out these parkways would only encourage speeding and dangerous driving.

New Mexico hit 50% climate-friendly energy in 2024 — well ahead of its 2030 target. The outlook is good for 80% by 2040, too: www.canarymedia.com/articles/cle... via @canarymedia.com

Sweet rock core closeup!

The ‘glass half full’ version is, CA is half way there! 20% reduction form 1990 levels and this year’s reduction was 3.9%, and improvement from last year. They’d still make the 40% goal by 2034 at this rate. Not perfect, but there would be 0% reduction if they didn’t try.

Elon Musk has spent more money on American elections in the last two years than George Soros has in his entire life.
