Love this (No) Limits story about Natalie Grabow who has continued to learn new sports over the course of her life and at the age of eighty completed the Kona Ironman. Amazing mentality, amazing role model.

Ah, no, neither Modi and the Indians nor anyone else has the right to surveil me in my home and watch me in my bathroom.

(Since when do US diplomats get to use American women in their bathrooms as bait or tools of appeasement.)

Wondering what your view is @govmlg.bsky.social on a person‘s right to privacy in his or her home, and especially when it involves multi-year high resolution video surveillance her bedroom and bathroom, not to mention a civilian committee of discussants.

Tomás Sánchez is a Cuban painter. His works are often in my mind. This painting, I believe, is from his 1948 “Enchanting Forrests” series.

For science related issues, I can be reached at the email on my website. In addition, I post often abt my work, and that of others, on Babel Blog.

The latest post is on Borges, Oulipo + the impoverishing power of being able to see everything everywhere all at once.

After ~23 years at the Institute—as grad student, postdoc, + professor—I’ve elected not to pursue renewal of my faculty contract. My last day was August 1st.

There are fundamental science advances on the horizon. . .more @ Babel Blog.

On Babel Blog—Borges, Oulipo, and the impoverishing power of being able to see everything everywhere all at once.

This post isn’t abt Oulipo per se but abt value in boundaries + constraints, when self-imposed or cooperatively adopted, rather than imposed by others.

Any potential project is at least a year off + there are no guarantees given continuous petty nonesense.

Delays serve to aggravate, undermine confidence in skills, + push start dates further into the future.

Had decision-making been intelligent, projects could be starting now. 🤨

delight I felt as a child watching an evening performance of Midsummer's Nights Dream at Virginia's Lime Kiln Theater.

Santa Fe Opera is truly magical. On my to-do list is the Oregon Shakespeare Festival in Ashland (as well as a visit to the nearby Rogue Brewery).

Thinking this morning about memorable + enjoyable performance venues. I loved watching Buena Vista Social Club on a warm summer night while picnicking in Atlanta's Chastain Park ampitheater (I lived in Little Five Points).

I often recall the total...

Fitness—including walking outside in 'natural' areas—is likely the most underused yet effective medical intervention available—and for a range of ailments from mental health to cancer. Want to improve public health while decreasing healthcare costs? Start thinking outside box abt food + fitness.

1. Subfivisions and other housing projects that backup against National Forests increase fire + flood risk. Playing fields, dog parks, and small, produce-producing farms could provide multi-functional buffers. Think about how space might be intelligently reorganized +

Fermented coconut thickened with tapioca. This is store bought (as my kitchen is ill equipped at the moment for more serious cooking).

It can be used with or in place of cream and eggs to make ice cream. One of the best textured ice creams I've made was a fennel pollen ice cream that used this...
