High-Sensitivity Fiber Interferometer for Gravitational Phase Shift Measurement on Entangled States
In this contribution, we describe the status of our experiment aimed at measuring the gravitationally induced phase shift on path-entangled photons. We use a kilometer-scale fiber interferometer whose arms are vertically displaced in the Earth gravitational potential, allowing photons propagating at different heights to accumulate different phases. To date, this is the first experiment to measure this effect on massless particles, thereby experimentally combining general relativity and quantum …

"Patricia #Espenak announced in an email that Fred passed away yesterday afternoon," Michael Zeiler just wrote on the Solar Eclipse Mailing List: "Fred was in hospice at their home in Portal, Arizona. Pat was holding his hand when he passed away and is devastated.
Fred had an extremely consequential life and was a giant in the solar eclipse community. Let‘s remember his enthusiasm for nature‘s greatest spectacle, his warm friendship to many of us, his generosity in sharing his knowledge, and his impact on all of us."

The US supreme court on Friday permitted DOGE, the so-called ‘department of government efficiency’, broad access to personal information on millions of Americans in Social Security Administration data systems while a legal challenge plays out.
At the request of the Justice Department, the justices put on hold US district judge Ellen Hollander’s order that had largely blocked Doge’s access to “personally identifiable information”
in data such as medical and financial records while …

Pretty amazing. And yet, the majority of Americans won’t see this story because the truth is paywalled but the bullshit is free. Which feels more and more to me like one of the world’s most important problems.

Getty Images spending millions to battle a 'world of rhetoric' in AI suit, CEO says
Getty Images is spending "millions and millions of dollars" on its legal case against Stability AI, the photo licensing company's CEO Craig Peters told CNBC.

1/N Ylistäkäämme Maailman polkupyöräpäivänä polkupyörän monipuolista vastuullisuutta, josta ei puutu oikeastaan mitään elementtiä:
SOSIAALINEN VASTUULLISUUS: Polkupyörän ansiosta työväki pääsi aamulla töihin tai vaikka illalla mielenosoituksiin aamulla vaikkei omistanut hevosta, tai vähän myöhemmin autoa. Naisetkin pääsivät pois kotoa hellan ja pyykkäyksen äärestä singahtamaan kylille tarpeesta ja vaikka ilman tarvetta.
