February 6 at 3pm (France) Marin Soljacic, a distinguished guest, will address the question: Can AI help/produce discoveries in photonics? An important question, even if it seems provocative. Free webinar by the GdR ONDES andComplexe, and the French Optical Society. www.sfoptique.org/pages/sfo/wa...

I think a lot about what Carl Sagan said in one of his final interviews.
"WE'VE ARRANGED A society based on science and technology, in which nobody understands anything about science technology. And this combustible mixture of ignorance and power, sooner or later, is going to blow up in our faces. Who is running the science and technology in a democracy if the people don't know anything about it?"
"Science is more than a body of knowledge, it's a way of thinking. A way of skeptically interrogating the universe with a fine understanding of human fallibility. If we are not able to ask skeptical questions, to interrogate those who tell us that something is true, to be skeptical of those in authority, then we're up for grabs for the next charlatan, political or religious, who comes ambling along."

This “Christmas tree” with the design incorporating Fresnel optics, was in operation at the Vilan Cap Lighthouse in Galicia from 1896 to 1964! the light reached 64 km. I wish you a wonderful holiday season with your family.

Mathematical physicist Cécile DeWitt-Morette was born #OTD in 1922. She made foundational contributions to Feynman functional integrals, organized the first American conference on general relativity (important for gravitational waves), and started the Les Houches Summer School. 🧪 ⚛️ 👩‍🔬 (1/n)
