IF YOU BUILD A BIKE LANE THAT DOESN'T CONNECT TO ANOTHER BIKE LANE THEN YOU DIDN'T BUILD A BIKE LANE

There is no line connecting "chaos"
(popular realization that since 1947 physics has had 3 legs: experiment, simulation, theory) and the day's techno fascists (any advance in our understanding of the world can be used to better or lives, or to commit new kinds of crimes).
None.

Preceding "chaos" there was "gauge invariance" in quantum field theory, to many of us as important as "chaos". But guess what, that never became a popular craze 😂

Artifact of our colleague Jim Yorke using "Chaos" in a title of a math article that had nothing to do with chaos.
Things about fads is that they come an go, but good science is forever. It motivated a few smart kids to become scientists, and that we are grateful for.

This week is infertility awareness week.

Kallmann Syndrome. More rounds of fertility treatment than I can count (high double digits). Six pregnancies. Losses from 8-22 weeks. One amazing five year old.

This journey is really hard, but you are not alone 🧡

This composite black-and-white photograph with an inset movie poster honors Baroness Karen Christenze von Blixen-Finecke (née Dinesen; 17 April 1885 – 7 September 1962), the Danish author who wrote under the pen name Isak Dinesen. In the main portrait, Blixen appears in her later years, seated indoors against patterned wallpaper with a framed painting visible behind her. She wears a dark ribbed cardigan over a light turtleneck sweater, her hair neatly styled. With a gentle, knowing half-smile and direct gaze toward the viewer, she holds a small dark object in both hands, her expression conveying quiet intelligence, warmth, and literary poise. Overlaid in the upper right is the iconic poster for the 1985 Academy Award-winning film Out of Africa, starring Meryl Streep and Robert Redford, directed by Sydney Pollack and based on her bestselling 1937 memoir.The layered composition blends personal portrait with cinematic legacy, evoking a mood of elegant reflection and enduring storytelling. Blixen’s key achievements include her vivid accounts of running a coffee plantation in colonial Kenya (1914–1931), captured in Out of Africa as well as Seven Gothic Tales and the story “Babette’s Feast” (later an Oscar-winning film). Her lyrical prose, written in both English and Danish, made her an international literary icon and two-time Nobel Prize nominee. This image powerfully symbolizes her life bridging Africa and Europe, forever linking her to themes of love, loss, and the African landscape that defined her voice.

A black and white photo of Fermilab’s first Director, the physicist Robert R. Wilson. He is seen from the shoulder’s up, resting his head against his hand as if he was looking up from working on a hard problem at his desk. Wilson has glasses, a while collared shirt, and a dark necktie.

Robert Wilson, Fermilab's first director, testified in front of the Congressional Joint Committee on Atomic Energy #OTD in 1969.

In making the case for building Fermilab he delivered a lovely and memorable justification for a national commitment to funding basic science. 🧪 ⚛️ (1/n)

I probably spend way too much time laboring over things like photo selection, but when you have a playground like AIP's Segrè collection it's irresistible. I've always thought young JRO has a Bob Dylan vibe, and this parallel was too good to pass up.

A vibrant color studio portrait of Carolyn Widney Greider, the American molecular biologist and Nobel laureate who discovered the enzyme telomerase and shared the 2009 Nobel Prize in Physiology or Medicine for revealing how chromosomes are protected from shortening during cell division. In this warm, professional head-and-shoulders photograph, she faces the camera directly with a bright, genuine smile that reveals her teeth and lights up her eyes, conveying warmth, intelligence, and quiet confidence. Her shoulder-length, wavy blonde hair frames her face softly. She wears a bright turquoise ribbed knit cardigan with a draped collar over a black top, accented by small blue stud earrings. The background is a soft, out-of-focus gradient of blues and greens that keeps the focus entirely on her approachable presence. The overall composition is clean and intimate. The mood is one of joyful accomplishment and scientific dedication, powerfully symbolizing Greider’s groundbreaking contributions to molecular biology, our understanding of aging, cancer, and cellular immortality, and her role as a trailblazing woman in STEM.

A black and white photo of Stanislaw Ulam. He is seated, visible from the chest up, wearing a light gray suit and holding a cigarette to this lips with two finger on his right hand. Ulam is looking directly at the photographer. The left half of his face is partly in shadow, he has dark eyes, and there is a slight wave to his short hair. The photo is tilted a bit, off-kilter.

Mathematician Stanislaw Ulam was born #OTD in 1909. He co-discovered cellular automata with von Neumann, proposed the idea of nuclear pulse propulsion behind Project Orion, and, regrettably, pitched the idea that led Teller to the hydrogen bomb. 🧪 ⚛️

NEW: We’re joined by 75 organizations in calling on Meta to cancel plans to install facial recognition technology on their “smart” glasses.

This tech would allow anyone who wears the glasses to identify and spy on those around them.

Meta must stop this all-out assault on our privacy and safety.

Definitely excited to see European governments pushing Linux adoption, but what I *really* want to see some government or institution do is fund a really good open-source alternative to the Google Office suite. (Yes I know there are some existing office solutions, no they don't suit my needs).
