Dark energy, the mysterious phenomenon that causes our universe to expand, appears to be weakening over time. A new formulation of string theory predicts a value that closely matches this observation.
String Theory Can Now Describe a Universe That Has Dark Energy | Quanta Magazine
In an unprecedented step, researchers crafted a detailed model compatible with the universe’s accelerated expansion.

Castor, one of the stars marking Gemini's twins — and one of the brightest in the sky — is actually a sextuple star, a *six*-star system! Now, for the first time, astronomers have split some of those tightly bound stars.

Very sorry to hear of his passing. The Computer Chronicles archive on the Internet Archive is one of the most essential records of tech history there is. Demos of so many products, from the iconic to the forgotten.
A goodbye to Stewart Cheifet, who hosted Computer Chronicles and Net Cafe, two critical computer news programs through the 80s and 90s. His entire collection was handed to the Internet Archive a couple years back. They are being re-digitized where needed.

Yeah, kept looking online and couldn't find anything that could read these ICQ files. Kinda gave up hope. Luckily I'm a digital pack-rat and keep everything. Just had to wait for the technology to advance to the point where this data was accessible again.

One fun project I gave Opus is to reverse engineer these old ICQ proprietary binary log files I had lying around from the late 90s (which it did after a few tries), store them in a db, then build a slick webapp for me to browse, search, etc, my message history. Super impressive.

Our team has been using Cursor for the past month, and we’ve been blown away by it. It has significantly changed our roadmap for what we can deliver in the coming months. Opus 4.5 is our go-to choice. However, we went through our token budget fairly quickly, so we try to use it wisely.

We are pleased to announce our discovery of #GW241011 and #GW241110
Both come from binary black holes where one black hole is much larger than the other. The larger black holes have large spin. Could these black holes have formed in a previous merger?

“It’s hard to overestimate the influence of Fourier analysis in math,” said mathematician Leslie Greengard. “It touches almost every field of math and physics and chemistry and everything else.”
What Is the Fourier Transform? | Quanta Magazine
Amid the chaos of revolutionary France, one man’s mathematical obsession gave way to a calculation that now underpins much of mathematics and physics. The calculation, called the Fourier transform,…
