107 years ago today (May 29, 1919), Arthur Eddington photographed a solar eclipse from a remote island off Africa — and proved Einstein’s General Relativity was right, overturning 250 years of Newtonian physics, and showing again that unconventional idea many times changes the arch of discovery. One of the greatest moments in discovery history 🌑✨

For my six @NavalAcademy classmates who gave their lives in military service, on the Memorial Day.
Below is Memorial Hall at the Academy, which was completed in 1906, and the “Don’t Give Up the Ship” flag was hung there in 1924:
"Dedicated to the honor of those alumni
who have been killed in action defending the ideals of their country.
With immortal valor and the price of their
lives these proved their love of country
and their loyalty to the high traditions
of their alma mater by inscribing with
their own blood the narrative of their deeds
above, on, and underneath the sevens seas.
They have set the course. They silently
stand watch wherever navy ships ply
the waters of the globe. "

Congrats to my friend and colleague @DeputySecState Chris Landau!
I’m honored that @POTUS @realDonaldTrump has named me Acting Director of the @PeaceCorps in addition to my responsibilities at the @StateDept. Volunteers serve in more than 60 countries, including Paraguay 🇵🇾 where I grew up and Mexico 🇲🇽 where I served as US Ambassador. Today I introduced myself to the team at headquarters in Washington and invited comments on how we can improve the organization. I similarly welcome input from users on this platform, especially those who have had experience (whether positive or negative) with the organization. 🇺🇸

With support from @CommerceGov, @IBM is announcing its plans for Anderon, America’s first quantum foundry that will accelerate American quantum leadership and enable advanced quantum wafer manufacturing.
This initiative marks one of the most significant commitments from the U.S. government in quantum R&D to date, and is poised to fuel American economic growth and quantum innovation. Learn more here: ibm.co/6010EMDli

Today President Trump, @CommerceGov and Secretary Lutnick announced the signing of 9 letters of intent to provide $2.013 billion in federal incentives under the CHIPS and Science Act in the quantum computing and first quantum chip foundaries sectors.
These funds will support a portfolio of quantum companies, including two domestic quantum foundry companies and 7 quantum computing companies to accelerate solving the most critical technology challenges in the race to develop utility scale, fault-tolerant quantum computers.

IBM wants to turn its captive quantum fab into an industry fab. A proposed $1B CHIPS award $1B @IBM cash plus IP and workforce spins out "Anderon", what could be America's first foundry purpose-built solely for quantum manufacturing.
Not greenfield. IBM has been fabricating Loon and Nighthawk on 300mm at NY CREATES Albany since November 2025. Anderon is the corporate spinout, capitalized for merchant scale. Superconducting qubits and supporting electronics first, with stated intent to expand modalities.
When I toured Albany NanoTech a couple of years ago, the read was R&D campus, not high-volume manufacturing.
It's a Letter of Intent. The $1B is proposed, not awarded. Definitive agreements still to come.
CHIPS Act scope expansion is the right call. National security and economic value don't stop at 2nm.
Three U.S. paths to quantum manufacturing are now in motion. SkyWater (IonQ-owned) takes third-party work as a general-purpose foundry. PsiQuantum runs photonic at GlobalFoundries. Anderon enters as the only dedicated, focused, and government-backed. The U.S. quantum merchant market just got more serious.

My mother Pearl Dabbar was one of the first women in the @StateDept foreign service after passage of the Foreign Service Act of 1946. Here is a picture of her in ~1948 as a part of the State detachment to Army Occupation Command, Tokyo. Her second assignment was Bonn, FRG. Motivated my many years of service, including today

Today, thanks to President Trump’s AI Action Plan, @CommerceGov and @NIST’s Center for AI Standards and Innovation have released a groundbreaking evaluation of American vs. adversary AI.
Result: American AI models dominate. Our systems outperform DeepSeek across nearly every benchmark.
The report is clear: DeepSeek lags far behind, especially in cyber and software engineering. These weaknesses aren’t just technical. They demonstrate why relying on foreign AI is dangerous and shortsighted.
Allowing our adversaries to control AI poses serious risks to our security. By setting the standards, driving innovation, and keeping America secure, the Department of Commerce is helping ensure continued U.S. leadership in AI.
