Since search is dead, how soon do you think Google Scholar is headed for the Google Graveyard? I'm betting it's soon, and academia is NOT prepared
Google Scholar Is Doomed
Academia built entire careers on a free Google service with zero guarantees. What could go wrong?

New preprint!
Simulating the dynamics of open quantum systems is a major computational bottleneck, largely due to the exponential scaling of density matrices. We're tackling this challenge head-on. 🧪

Fearing yet more war;
hoping for peace.
May war-mongering leaders be removed, and innocents everywhere be safe. What else is worth saying?

Quantum tunnelling may be common at the tiniest scales, but no one had ever observed the phenomenon in fluorine - the element was simply thought to be too heavy. Now, this accepted wisdom has been upended in new experiments that observe fluorine tunnelling

The conceptual consequences of Noether’s theorem are hard to overstate.
How Noether’s Theorem Revolutionized Physics | Quanta Magazine
Emmy Noether showed that fundamental physical laws are just a consequence of simple symmetries. A century later, her insights continue to shape physics.

These are real images of exoplanets.
Four super-Jupiters, imaged 10 times over 12 years around a star 133 lightyears away.
These are real, giant worlds, out there in the dark.
And we can see them.

Git was 20 years old this week. Written by the creator of Linux as a tool to streamline his workflow - it shows the importance of making tools. If you have a better way of doing something, write and share it. It's possible that few others understand the problem, let alone have the solution you do!
Linus Torvalds knew what developers wanted for their SCM: Performance, safeguards against data corruption and distributed workflow.

We just need to turn the negative productivity of scientists at NASA and IRS auditors that DOGE fired to gainfully making shoes in Nike factories reshored from Vietnam.
This is the groundbreaking economic thinking of communist purges from Mao to Pol Pot with a sprinkle of American Exceptionalism.

In 25 years of covering national security, I’ve never seen a story like this: Senior Trump officials discussed planning for the U.S. attack on Yemen in a Signal group--and inadvertently added the editor-in-chief of The Atlantic. www.theatlantic.com/politics/arc...
The Trump Administration Accidentally Texted Me Its War Plans
U.S. national-security leaders included me in a group chat about upcoming military strikes in Yemen. I didn’t think it could be real. Then the bombs started falling.

1. For the past thirty years I've had the best job in the world.
I've had the opportunity to follow my curiosity; explore the workings of nature and society; mentor students and junior colleagues in the same process; and teach generations of students about it all.

Remake of an old animation about quantum tunnelling in the time domain.
🧪⚛️💡
A few details:
* The incident and reflected wavefunctions interfere, creating fringes when it hits the barrier.
* Even when far away from the barrier, the wavefunction is slowly broadening.

"a remarkable 14% admitting that they put in significantly more than four hours — sometimes a full eight-hour day or even more"
First, "admitting"? This is not a source of shame!!
Second, the only remarkable thing to me is that it's so low. I can't imagine reviewing a theory paper in <4 hours.
