You Won’t Believe How the Sun Moves Through the Galaxy! ☀️
Earth takes one year to orbit the Sun. The Sun needs about 230 million years to complete one orbit around the center of the Milky Way. That’s one “galactic year.”
At roughly 4.6 billion years old, our star has completed only about 20 of these enormous orbits.
Nothing in space stands still. As the Sun moves around the galaxy, the planets keep orbiting the Sun. Earth’s yearly journey happens within a much larger journey through the Milky Way — both motions happen at the same time.
And the two orbits don’t line up: the plane of Earth’s orbit is tilted by about 60° relative to the galaxy’s disk. The familiar flat diagrams of our Solar System show only part of how we move through space.

☎️ Calling all students:
You can now access hundreds of textbooks directly in Notebook, for no charge. From publishers like S Chand Publishing, OpenStax, and Open Textbook Library— browse, select and upload them as sources to ace all of your upcoming exams (no more excuses, ok?)

In my role as PhD advisor, I'm nowadays just telling my students to pick an important problem:
1. That is not trivially solvable by AI today
2. That is not theoretically unsolvable
3. For which a solution technique will just get better with AI advancements, not obsolete.

Raghu Mahajan, back in June: quantum gravity isn’t the right target for AI yet. Maths problems are well-defined and checkable. In quantum gravity, the concepts themselves are still evolving.
TheoPhysEval this month fits his picture. Agents solved 49 of 50 unpublished physics problems, and the authors still point to “the current lack of agent-led breakthroughs in theoretical physics.”
Maybe the bottleneck in quantum gravity was never solving the problem. It’s knowing what the problem is.

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! 😉

A phone is more than just technology. It’s minerals, too.
Minerals are essential to the devices we use, the infrastructure we depend on and industries across the country. Getting those materials from the ground to the products we use, however, involves complex global supply chains.
USGS scientists track mineral production, demand and trade around the world. Where minerals come from, how concentrated their supply is and how easily supplies could be disrupted all help reveal potential risks to U.S. industries and the economy.
Each year, the USGS publishes Mineral Commodity Summaries, which brings together data on more than 90 mineral commodities across 180 countries. The report covers U.S. production, imports, exports, consumption and recycling, as well as global production, reserves, prices and market trends.
These data also help inform the Nation’s List of Critical Minerals, which identifies minerals essential to economic and national security that are vulnerable to supply chain disruptions. The 2025 list includes 60 mineral commodities.
The next time you pick up your phone, remember that the minerals inside it are part of a global supply chain. USGS science helps decision makers understand these connections and prepare for potential disruptions.

Terence Tao warns that the race to AGI is becoming toxic, and OpenAI’s massive paper dump wiped out junior research projects overnight.
Some parts of his most recent interview:
“They were willing to toss understanding to the side so that they could prove more theorems, get more press releases [...] and test their latest toys.
These AIs are depleting our pool of questions and not replenishing them with anything new.
only looked at about 10 of the 300 odd papers. I mean, so this is part of the thing. There's just so many to look at.
[...] There's a whole bunch which are still incomprehensible. And no one's really gone through them, and one or two even have some errors and [were] retracted.
So we don't have a clear picture of what's going on. And no one from OpenAI is helping us. As far as they're concerned, they're done.
[...] We have this pile of stuff to go through which we didn't ask for, but we have it anyway. And there will be some good stuff in there and some rubbish, but we don't know what the percentages are yet.”
